ForewordOn behal o the Presidio Trust, I would l ike to express our gratitude or EDAW's
excellent work on the Fort Scott Creek & Historic Gardens project. We were thrilled to
have the Presidio selected as the ocus o EDAW's "usion" initiative or this year, and our
expectations or both the design process and end product were more than exceeded.
As managers o an incredibly complex landscape, we are continually challenged to strike
a balance between competing demands -- rom ensuring that the park's environmental
and historic treasures endure to providing memorable opportunities or the public
experience [o] the Presidio. It was rereshing to have such a talented and dedicate d
team come to the park and help us creatively explore new opportunities to balance
and achieve these various mandates. It was a rigorous week, and we were all very
impressed by the process and the outcome.
In particular, I want to acknowledge the exceptional team that EDAW sent to the
Presidio including Alma Du Solier, Alex Felson, Leo Edson, Debra Bishop, and Dawn
Cunningham. They were an extremely dedicated and talented group o proessionals.
We very much enjoyed working [with] them and I continue to receive positive eedback
rom the many people who engaged with them over the course o the week.
We deeply appreciate the contribution EDAW made in helping progress plans or the
Presidio's uture, and we look orward to working with your talented sta again.
Sincerely,
Micheal Boland

In November 2006, a week-long workshop ocusing on both ecology and landscape
design was conducted at the Presidio o San Francisco. The goal o the workshop
was to develop conceptual design plans or the Fort Scott Creek + Historic Gardens
project that would bridge the divide between ecology and design, and identiy applied
techniques or this approach in the uture. We started with the assumption that
designers and ecologists working together could produce better design solutions
than those resulting rom more independent work patterns. We discovered that ourunderlying disciplinary assumptions, the tendency to rely on what we do best, and
limited opportunities or ecologists to participate in the design process, all create
challenges or usion among disciplines. At the conclusion o the workshop, the
team was able to identiy moments o successul integration as well as missed
opportunities or collaboration and develop a diagram depicting the dynamic. This
book presents ndings about ways to acilitate interdisciplinary design and ecology
work, describes the workshop collaboration and outcomes, and analyzes the process
o designers and ecologists working together.
Introduction
What is more valuable in an urban park setting: public access to water or riparian
wildlie habitat preservation and enhancement?
Can public use and recreation be integrated with both habitat enhancement and
controlled visitation?
What takes precedence in a historic national park: ecosystem unction or
historic preservation?
Key Questions
How can one ensure that opposing stakeholders reach a winning consensus rather
than everyone eeling that they have given up too much?

EDAWs Client + Practice Initiative on Design and Ecology ocused on building a
dialogue between practitioners o dierent disciplines within the rm. Ater extensive
discussions on how ecology and design might be integrated (Fig. 1-1), the team
sought either a client or a project that provided the right blend o circumstances to
apply an integrative design approach. The team ound this blend with the Presidio.

In the summer o 2006, two landscape
architects, a wildlie biologist, and a
restoration ecologist rom EDAW teamed
together to orm an initiative exploring
the usion o ecology and design. The
EDAW team approached the Presidio Trust
in search o a pilot project or the rmsEcology and Design Initiative. EDAW has
viewed the usion o ecology and design
as a undamental aspect o its work or
decades. This unded eort emerged rom
conversations between EDAW ecologists
and designers seeking to elevate ecological
design to a higher level throughout the
rm a level where meaningul ecological
unction and value is incorporated into the
design on multiple projects.
The Presidio Trusts commitment to
achieving a balance between the parks
environmental and historic treasures, and
its past success in completing projects that
incorporate meaningul restoration ecologywith public use and design elements. This
bridging o ecology and design indicated
a natural t or the initiatives pilot project.
For the ocus o the workshop, Presidio
Trust sta proposed the Fort Scott Creek +
Historic Gardens site. The site is slated to
become a uture Center o Engagement
ocused on sustainability.
With the goal o exploring the dilemmas
and opportunities o interdisciplinary
design, the team participated in a
one-week site-based visionary and
consensus-building workshop or the
Fort Scott Creek + Historic Gardens.
Collaborating with the Presidio Trust,EDAW sought to achieve a balance
between enhancing public uses
and conserving the parks valuable
environmental and historic resources.
This partnership with the Presidio Trust
enabled EDAW to explore the intricacies
o stakeholder dierences and site
constraints. Applying ecological and
design lenses to the Presidio, the EDAW
team exposed a number o key challenges
in the integration o these two disciplines,
and acilitated a process o exploration or
resolving these conficts.
A key goal on our part was to acilitatecommunication and idea exchange
through planned discussions and
inormal interactions such as site walks.
We organized the week's schedule to
oster a continual dialogue between
the designers and ecologists (Fig. 1-2,

Integrating Design
and Ecology
The increasing demand or sustainable
urban designs, green building, and
green inrastructure requires a deeper
ecological understanding o urban
environments. While ecologists currently
contribute to the design and construction
o cities as consultants on design teams,urban ecology remains a fedgling eld
with weak theoretical underpinnings and
a limited shared vocabulary.
Most ecologists today avoid human-
dominated environments, ocusing
instead on sites that are not primarily or
human use. Ecologists are happy i they
understand a system, while designers
aim to invent something new. When
ecologists do get involved in design,
such as through restoration ecology,
they typically employ a naturalistic design
aesthetic and work toward hiding any
evidence o the human hand. This
contrasts with the goal o designers, who
oten want to make a project visible.
One key issue to address in dening
urban ecology is what role people,
technology, and the political and socio-
economic aspects o human society play.
Most existing quantitative research
investigates ecology in cities, ocusing
primarily on plant, animal, water and
nutrient fows occurring in urban
settings, while avoiding the challenge
o translating political, cultural, social
and economic actions into ecological
terms. People and the city are viewed in
these cases as external orces aectingbiological conditions.
Ecology o cities takes a more holistic
view o human society and its interace
with biological processes, looking at the
ecological implications o socio-cultural,
political, and economic urban patterns.
Various methods used to measure inputs
and outputs o a city include system
metabolism at a variety o scales:
building, neighborhood, watershed, city,
or region. Urban ecology also examines
the spatial distribution o these scales and
the circulation o people and materials
(Spirn 1984).
Unraveling the ecology o urban
environments and translating people
and culture into ecological terms may
not be so easy. Unlike more natural
environments, cities are the result o
human design rather than the product
o millions o years o evolutionary and
biogeograph ic processes. EcologistsFigure1-3 Human-Nature Diagrams

investigating cities ace the dicult task
o incorporating the physical, cultural,
economic, and political urban terrain
into their research and analysis. This
requires not only grappling with a number
o variables never beore dealt with in
ecological research, but also developing aposition on what urban ecology includes
and excludes, and understanding to what
degree human patterns are ecological
(see Fig. 1-3, Human-Nature Diagrams).
Fundamental conceptual questions
remain. Should humans be thought
o (like other biological organisms)
as ecological actors? I so, can we
consider our manuactured systems
(such as HVAC or zoning) ecological?
What weight or value should human
and biological infuences that shape
urban spaces be given (see g 1-4
-- Mapping Urban Ecology)? Can natural
areas remain unctional as healthy
ecosystems while also allowing
human uses?
Without understanding interactions
and eedbacks between human and
ecological systems, our view o
ecosystem dynamics both at local and
global scales will be limited as will be
our ability to apply these insights to public
policy and land management.
(Grimm et al., 2000).
The ambiguity o "ecology" as it occurs
in human-populated environments, and
the lack o terminology or ecological datadescribing the ecology o buildings, urban
space, and other human constructed
landscapes thwarts eorts to bridge
disciplines. To help dene this usion
zone, a new vocabulary along with a
series o metrics based on viable empirical
data needs to be developed. Pre sently,
the lack o denition or documentation
o the new ecological conditions created
in urban environments make it dicult
or designers to absorb ecological
understanding into the design process.
In order to access a greater range o
ecological approaches, designers need
to go beyond environmentalism and
prescriptive design techniques, and take
greater advantage o ecological science.
While green design is becoming
increasingly important to government
agencies, clients, investors, developers, and
designers, all parties are still working with
limited knowledge o what actions will

lead to sustainable development. Once
implemented, questions still remain on
how to maintain and operate the systems
to provide prolonged sustainability.
Ecologists also lack extensive, rigorously
tested research about the unction
o urban ecosystems -- includingdense urban, suburban, exurban, and
browneld sites. Oten, in the absence
o sucient inormation, designers must
make educated guesses. Given the
uncertainty and diculty o predicting
uture outcomes o dierent strategies,
developing eective sustainable practices
requires testing and monitoring to ensure
accurate inormation about the success
o systems being implemented. More
rigorous and long-term research o urban
ecological processes and patterns is
necessary to evaluate the ecological
impacts o the various developments
occurring in managed sites.
Ecologists have the potential to make
signicant contributions to urban
design practices. They have already been
contributing to the design and construction
o cities through their roles as consultants
(applied or restoration ecologists and
ecological engineers) on design teams.
Still, addressing urban ecology remains a
new rontier, not least because current
theories that dene cities and human
activities in ecological terms are relatively
rare. Today, ecologists and designers
have an opportunity to bridge the gap
between ecological analysis and urban
design to reorient society towards a moresustainable uture.
Incorporating ecological research
components into urban development is
a crucial part o advancing sustainability.
Not only will it provide opportunities or
a growing population o ecologists to
establish research sites.
A key goal to this usion eort is to
develop enduring solutions. These
vibrant and long-lasting designs could be
evaluated or perormance and adapted
overtime or eciency.

Contrasts between the
Ecological Science and
Design Proessions
While there is growing interest in
bridging the gap between practices
to acilitate green design and urban
ecology, designers and ecologists dier
in signicant ways that could slow the
process. Designers and ecologists rely
on dierent skill sets, approaches, andtechniques to explore and comprehend
complex sites. The se dierences lead to
a lack o dialogue or to communication
breakdowns. While designers direct a
creative energy towards realizing human
experiences o a landscape, ecologists
typically use a quantitative process or
understanding specic environmental
processes and patterns (Fig. 1-5).
Despite the unique paradigms o these
two distinct proessions, todays land-
based challenges require integrated
approaches and inputs to solve complex
problems. Solutions need to arise not
only rom an overlapping o disciplines,
but rom a consistently integrated
dialogue between ecologists and
designers. This broadening scope o
opportunities demands new approaches
and input provided by interdisciplinary
teams. In particular, the study o
urban areas and other human-modied
landscapes requires knowledge o
ecosystem processes as well as o the
physical, cultural, economic, political, and
ecological complexities o urban systems.
Fig. 1-4 conceptually illustrates how high
design and rigorous science might overlap
to provide a usion zone. Integration
o these approaches requires a candiddialogue where dierences are exposed
and goals are revealed at the start.
Collaboration and commitment to dialogue
are essential. The usion zone represents
synergy, wherein all parties participate and
are prepared to discuss concerns or ideas
reely at any point.
Recognizing the need or an understanding
o how to acilitate design and ecology
collaboration, EDAWs Client + Practice
Initiative has provided support or a
multidisciplinary group to team with a
client and explore novel situations. The
Presidio Trusts need or consensus-
building among stakeholders provided
a perect partnership opportunity or
exploring how the synergy o design and
ecology could help overcome obstacles to
achieving interdisciplinary solutions.
Ecologists have traditionally avoided
human-inhabited environments.
Designers modiy the environment to
cater to human needs.

Applied Ecologists Approach
Process
Grounded in Scientic Method: A s a
science-based practice, ecologists attempt
to adhere to a more objective approach,
combining statistics, math, and computermodeling with biology, natural history,
experimental research, and observation.
Scale
Individuals to Population or System:
From micro-organisms to populations,
communities, and landscapes, ecologists
work at a broad range o scales in seeking
to understand ecological dynamics.
Scales are in part determined by where
ecologists can identiy and interpret
boundaries. The ecologists scale o work
has traditionally been limited to the extent
o the system or population studied. In
addition, ecologists are oten nancially
constrained or limited by the logistics o
setting up large-scale experiments.
Product
Findings/Conclusions: The output o the
scientic method is ndings or conclusions
which negate or support a hypothesis
based on the initial research question.
Researchers conclusions are generally
stated to specically answer the question
and address the hypothesis. Interpretation
and applicability o these ndings to other
scenarios requires scientists to step outside
o replicating experiments and to accept a
level o uncertainty. Due to the unding and
time constraints o conducting research,
ecologists must oten predict and render
judgment about likely outcomes
and conclusions.
Form
Driven by Science: Form is based on
statistical data and eciency. Experimental
strategies developed over time that identiy
boundaries raming complex systems, such
as watersheds. Experiments typically use
inexpensive materials with the simplest
processes or capturing desired data.
Restoration ecology is one o the ew
examples where ecologists make design
decisions. Oten the deault approach is to
design in a naturalistic manner. Designers
tend to view the naturalistic design and
strong environmental stances as obstaclesto bridging the divide between the practices.
Also, understanding the latest ecological
theories and nding ways o integrating
the scientic objective into design can be
complicated (Fig. 1-6A).

and environmental scientists are generally
interested in maintaining ecosystem
unction and processes. Traditionally,
ecosystem health and sustained operation
o plant, wildlie, water, and atmospheric
systems has been a dening goal o
ecological eorts. Increas ingly, human
systems and behaviors are being integrated
into the ecology process.
Designers Approach
Process
Making Concepts a Reality: Designs
emerge through a process o understanding
the site. Through a creative exploration o
potential site experiences, constraints, and
opportunities, designers produce solutions
that are realized in drawings, images, and
montages. Many scientists have diculty
understanding the value behind these
design methods, due to the use o
subjective language, a ocus on aesthetics,
and the design process (Fig. 1-6B).
Scale
A Parcel, Building, Park, or Regional Area:
The land-based, surcial scale o work is
dependent on the size and dened boundary
o land to be planned or designed. The
scales at which applied ecologists work
can dier widely rom the scales at which
designers work. A large project or a
landscape architect may a large-scale project
or an ecologist (Fig. 1-7).
Product
Representation: Design is a representation-
based approach, where designers utilize
various orms o diagramming, sections,
plans, computer modeling, and model-
making to analyze, explore, develop, and
build human-related spaces and buildings.
The exact and denite concept evolves
through the design process into a real orm.
A designers ability to adapt a concept to
meet the applied challenge is essential.
Form
Art/Design/Dialogue: Form captures
representative and symbolic interventions
infuenced by culture, history, politics,
environment, and social elements o a
site. Form is also driven by a designers
education and mentors as well as
interaction with various design dialogues.
Function
User Experience: Designers bring a
creative energy that is generally directed
towards achieving a desired human
experience o a particular landscape.
Landscapes can also be designed to
encourage particular processes.Figure 1-6B

Integrated Ecology and
Design Approach:
Opportunities or Fusion
Constraints are very oten the impetus
or innovation. Obstacles provide
opportunities or designers to acilitate
the progress o a team through design
challenges. Thus, designers ulll a
undamental role in building research into
urban sites and into social consciousness.
Scale
As cities become the subject o ecological
research, more opportunities arise or
designers and ecologists to communicate.
There is an increasing need or designers
and ecologists to work at multiple scales
to address the zone o usion between
their disciplines. Ecologists understand
complex systems, and can provide
multiple levels o analysis or designers.
Practitioners should search or scales that
complement one another.
Product
Integrated projects that incorporate design
and ecology will be long-lasting, dynamic,
and intimately tied to human society.
Form
A designers creativity and exploration
plays a unique and critical role in situating
ecological research and analysis within a
Process
Ecologists are increasingly interested
in experimentation, conservation, and
restoration on urban sites, expanding rom
their traditional presence in less human-
dominated landscapes.
Ecologists are broadening denitions
o ecosystems, and (recognizing that
ecological systems are continually being
infuenced by disturbances) revising
traditional vegetation theory to include
multiple processes, human infuences,
and spatial heterogeneity. Ecologists have
also moved rom considering populations
and ecosystems as relatively closed or
autonomous systems, independent o their
surroundings, to viewing both populations
and ecosystems as open and strongly
infuenced by input and output o material
and individuals across system borders.
Landscape architects have begun to take
on a larger role in understanding and
developing urban ecological systems.
They are beginning to appreciate an
ecological process-based understanding
o landscapes and environmental concerns,
and learning to access and incorporate
ecological knowledge into their design
processes (See Fig. 1-8).Figure 1-7

Utilizing designers creativity and
understanding o city composition,
evolution, orm, and unction, ecologists
could begin to grapple with the ecological
implications o urban space and culture
in their research. By uniying traditional
ecological research methods with urban
design, ecologists could take advantage
o designers ability to synthesize
multiple complex actors into cohesive
physical orms. This could in turn make
ecological research more public, visible,
and aesthetically ambitious, inusing
experiments with cultural meaning.

2. The Presidio: A Case Study in
Integrating Ecology and Design
Through a combination o presentations and site visits, the workshop began with a crash
course in the history and existing conditi ons o the site. The oundation being set, the
workshop progressed quickly rom discussions o interdisciplinary work, site analysis,
visioning with stakeholders, and design charrettes, to the creation o a conceptual
plan. Along the way lessons were learned about the integration o design and ecology,
although some were only apparent with the benet o hindsight. This chapter seeks to
take readers on our design and ecology integration journey.

Presidio as a Pilot Study
or Ecology and Design
The Presidio o San Francisco, a 1,490-acre
park located at the Golden Gate Bridge,
provides a rich context or exploring the
collaboration between designers and
ecologists. The Presidio is a distinct park
site located at the center o the world's
largest urban national park, Golden Gate
National Recreation Area (75,500 acres).
The Presidios mixture o land uses and
competing stakeholder demands within
an urban area has created a variety o
obstacles to reaching consensus on land
use decisions.
In use as an active military post rom
1776 to 1994, the Presidio was olded into
the boundaries o Golden Gate National
Recreation Area in 1972 ater being
designated a National Historic Landmark
District in 1962. Congress established The
Presidio Trust in 1996 as a leadership body,
and charged the Trust with preserving and
enhancing the Presidio as an "enduring
resource or the American public."
The parks 300-acre Historic Forest is a
designated historic landmark. The orest is
recognized by many as a cultural landscape,
shaped by the U.S. Army more than 100
years ago, that signicantly contributes to
the Presidios historic identity. Others view
the orest as a created, articial community
with limited diversity that replaced native
dunes, coastal prairie, and coastal scrub
communities. A highly charged discussion
on this topic has been ongoing or years.
Located in a highly urbanized center, the
vast green spaces at the Presidio seem to
be prime opportunities or diverse public
uses. However, historic designations
and stakeholders' interests oten create
opposing demands. For example, the
Presidio's buildings encompass 6 million
square eet. Many o the houses that
were once occupied by military amilies
are now occupied by civilian amilies; there
are nearly 3,000 people currently living in
these homes. These long-term site users
comprise a group o private stakeholders
inhabiting space within a public park.
Additional issues at the Presidio arise in
relation to other land management visions,
such as environmental restoration. These
projects prompt a series o questions.
What is the goal o restoration projects in
an urban context? Which is more important:
to restore a lands native ecosystem, or to
cater to human needs and try to allow or
some environmental value as well? In the
case o the Presidio, there are a number o
examples where restoration ecology proved
a useul tool in bringing dissenting voices

The Presidio Trust envisions the project
site becoming an important destination or
park visitors. Ultimately, the nearby historic
buildings may be used or conerences
and other events that could draw people
with a common interest in addressing
environmental and social issues. Historic
structures and artiacts, many o which
are yet to be restored, are common in and
around adjacent historic gardens. From
the gardens, a small spring-ed creek
emerges and meanders along a valley that
is itsel being restored to provide important
ecological unctions and values. Planned
native plant restoration will enhance
opportunities or park visitors to view
wildlie along Fort Scott Creek.
The Presidio Trust challenged EDAW to work
in a collaborative ashion with their technical
experts to develop a conceptual design
plan, which enhances, interprets, and
integrates the unique eatures o the projectsite. The initiative was originally ocused on
developing designs that incorporate ecology
and design into public use, education
and interpretation (Fig. 2-1A). As EDAW
prepared and participated in the charrette,
it became increasingly apparent that
historic actors were a major infuence. The
working model was expanded to integrate
ecology, design, and history with public
space (Fig. 2-1B).
Key Requests rom Client:
1. Develop a 21st-century approach that
is sustainable, integrates state-o-the-art
technology, and is respectul o the sites

2. Develop the restoration o Fort Scott
Creek and determine what role it might
play in relation to other riparian corridors,
as well as the historic landscapes.
3. Knit the district together, and tie the
historic garden and community garden to
the ideas o sustainability and stewardship.
4. Create an educational landscape with
evolving experiences.
5. Develop a landscape design that solves
issues and creates opportunities or
people moving through the site.
6. Childrens activities are key. Make this
a place where children in the Bay Area can

The Presidio Trusts mission (Fig . 2-3)
illustrates the inherent challenges o
planning, programming, and designing the
site. Natural areas, wildlie, and native

structures and designed landscapes
are also considered key resources to be
preserved or the public. Ideally there
will be diversity in the types o locations
preserved at Presidio: both natural areas
and designed landscapes. However, a
process or reaching consensus is required

Given site constraints, accommodating
stakeholder demands will be challenging.

A military presence can be traced to the
Presidio as early as 1776. In spite o this
human occupation o the site, until the
early 1800s the Presidio eatured extensive
sand dunes and coastal scrub extending
across the coastal blus (see Fig. 2-5).
Parts o the Presidio were also grazed
especially during the Spanish occupation,
leading to erosion and wind-blown sand,
which was carried and deposited across
the site. The US Army established a
military post at the Presidio in 1846.
In the 1890s, a decision was made to
modiy the existing landscape in order to
mitigate harsh winds, stabilize shiting
sands, and complement the natural
beauty o the land.
Over time, the demands on the land have

Community Gardens: Applying
Historical Methods to Secure
New Land Uses
The debates surrounding community
gardens at the Presidio are an apt
illustration o the conficting demands and
expectations placed on the land.
The Presidios role as a community where
people live and work, as a national park
at the edge o a highly urbanized area,
and its designation as a National Historic
Landmark District lead to inevitable
conficts. While community gardens are
uncommon in national parks, they are a
wonderul public use component o many
urban parklands. They provide a venue
or community members to invest in the
land, they create habitat or insects and
birds, and they can provide a means or
maintaining the land (although management
requirements may increase). The Nation al
Park System acts as a stakeholder at the
Presidio, oten nding its agenda in confict
with the surrounding homeowners, Presidio
inhabitants, and historic preservationists.
Historically, the site was established
as a pleasure garden or ocers and
their wives along with the Fort Scott
Creek area. Other gardens existed at
the Presidio during its military period,
including a victory garden and agricultural
gardens used to grow ood or the war
eort. The community gardens available
at the Presidio today include one historic
garden covering roughly a one-acre parcel
o land. The well-established Presidio
Native Plant Nursery also employs a
signicant number o volunteers, providing
avenue or community members to work
the land. The limited community garden
space at the Presidio does not satisy
existing public demand. There is a long
waiting list or users seeking garden plots.
Opportunities to expand the amount
o space or cultivation by community
gardeners are constrained by strict
guidelines and controls on the number o
gardens allowed to ensure maintenance o
an historic character. A variety o actors
including the Presidios historic district
designation which governs landscape
changes contribute to the limited gardens.
Competing land uses and the limited
availability o non-orested level land are
also actors.

In spite o these constraints, the
development o the current community
garden in the mid 1990s is a great
example o a way to move orward in
spite o stakeholder confict. Eager to
establish garden plots, the community
gardeners became historians by digging
out old aerials and images rom the
historical library to identiy possible
locations across the Presidio that had
once been used as pleasure gardens.
The original gardens within Fort Scott
were identied so that they could be
revived as gardens or the public.
Historic preservation o the landscape
makes increased public access and
public gardening interests dicult to
achieve. Some might view the lack o
community gardens as a lost public
benet. Histori c preservation limits
the realization o what many view as
an optimal land use allocation or public
involvement. The Presidio Native Plant
Nursery does provide some volunteer
opportunities to actively restore sites.
In several cases, the restoration
approaches may circumnavigate historic
preservation in order to both satisy
recreational needs and achieve a
beautiul landscape. The nurserys role
in providing land use opportunities,
which satisy urban residents demands
or community gardening while meeting
historic preservation constraints, is an
example o programming that can enable
additional public accessibility to the site.

Restoration Ecology: Providing a Way
to Align Stakeholders
Multiple restoration projects have been
undertaken since the U.S. Armys
closure o the Presidio base in 1994. A
review o these projects reveals the
planning and design challenges posed by
conficting and incompatible land uses,
precedent land management decisions,
evolving disciplinary, preservation, and
conservation approaches.
In 1994, The Army transerred the land
to the National Park Service, and with its
mission o preserving unimpaired the
natural and cultural resources and values
o the National Park System, the Park
Service began a airly broad restoration
eort (Fig. 2-8). In 1996, approximately
80% o the Presidio was transerred
to the Presidio Trust. Restoration can
be viewed as a undamental tool or
satisying both the National Park Systems
and the Presidios mission o enhancing
natural areas as enduring resources or
the public. The Natural Areas Program is
a program designed to preserve, restore,
and enhance San Franciscos natural
ecology and to develop community-
based site stewardship. The purposes o
Natural Areas stewardship are ecological,
historical, educational, aesthetic,
and spiritual.
Restoration ecology at the Presidio reveals
the challenges posed by conficting
interests and incompatible uses. It
raises the question: how can ecologically
appropriate restoration be compatible with
cultural and historic preservation interests?
In addition, it can be dicult to change
prevailing public perceptions o ecological
restoration. The public oten views
restoration as replacing a park-like setting
with a less user-riendly environment.
Mature trees are understandably a much-
loved component o parks, and restoring
areas o mature parkland to coast scrub or
grasslands, or example, may not always
mesh with the desires o urban residents in
need o respite.
The establishment o the Presidio Native
Plant Nursery provides a way or Presidio
Trust, community volunteer and ecological
goals to align. The Presidio Native Plant
Nursery supports habitat restoration,
creates a connection between the
park and the community, and helps
people understand the importance o
environmental sustainability, restoration,
and parklands stewardship. Sta and

volunteers grow 60,000 native plants
annually or habitat and orest restoration
projects throughout the Presidio, collect
seeds, care or plants, and construct
compost piles. There also exists in our
society a general lack o public knowledge
about the ecological merit o various
landscapes. Together these historic and
cultural actors position some stakeholders
against ecological restoration. The Presidios
highly urban context results in signicant
social demands on the land: or example,
residents want jogging trails and desirable
views rom houses. From a dierent
perspective, historians value the Presidio
landscape as historical documentation o
the past military presence.
Still, many environmentalists are calling
or the complete removal o the non-
native Historic Forest planted on site and
its replacement with what was originally
there, including sand dunes, coastal scrub
communities, and riparian habitats. The
riparian habitat restoration has more
easily garnered public acceptance, and
indeed there are now several successul
examples o Presidio restoration projects
that include coastal wetlands and creek
daylighting. The Presidio Trust also sees
value in ecological restoration as a strategy
restore a lands native ecosystem? Or
is it more essential to cater to human
needs, and allow or some environmental
value gained through public access to
natural areas? In the case o the Presidio,
there are a number o examples where
restoration ecology brought dissenting
voices together towards a common cause.
Establishing restoration projects on-site
attracts a substantial volunteer contingent
to help demolish, grade, and re-plant the
landscape. Public acceptance o and
participation in restoration projects can also
generate a sense o community ownership
and investment. While many restoratio n
projects at the Presidio have concentrated
on providing habitat or endangered plant
species such as Clarkia franciscanaand
Arabis blepharophylla, provisions have also
been made or public use, access, and
viewsheds. Thus, restoration has beneted
diverse interests, including historic
preservation, the natural environment, and
public access.
There are a number o concerns about
restoration ecology as an applied science.
How does a practitioner decide which
historical landscape is most appropriate
to reconstruct? The goals o restoration
to uphold its mission o providing resources
or public use. Extensive participation
by volunteers in restoration projects is
urther evidence o public acceptance o
ecological restoration.
Restoration at the Presidio provides an
interesting case study o the intersection o
planning, design, public use, ecology, and
history. In several cases at the Presidio,
ecological restoration circumnavigated
historic preservation to satisy recreational
criteria and public use. For the community
garden and other restoration sites,
gardeners and ecologists act as historians
or geographers, teasing apart the history
o the site through local knowledge, old
photographs, maps and knowledge o
what was once in the area. Ecologists
mine the evolutionary past to identiy
a prior landscape condition deemed
appropriate or restoration. Because o
the urban nature o the park, the resultant
built product may be a compromise
between an early landscape condition
and the needs o the present.
The battles at the Presidio reveal a larger
issue linked to environmental restoration:
what is the goal o a restoration project
in an urban context? Shoul d one aim to
such projects more dicult to und.
Additionally, because much o the projects'
systems are hidden, opportunities to
educate the public about the site
are curtailed.
Because this approach minimizes the role
o visible design, it discourages many
designers rom exploring congurations
and approaches that might have greater
ecosystem unction. An approach to the
built orms o restoration ecology that does
not always deault to the naturalistic would
promote a more dynamic relationship
between designers and ecologists.
maintained are naturalistic as opposed to
geometric in orm.
Somewhat predictably, ecologists and
designers have divergent views on
the orms that restoration should take.
Generally, ecologists want to create
something that looks like nature and does
not stand out, whereas designers want
to reveal the human hand. Naturalistic
design, by denition, brings little attention
to itsel. As a result, the public tends not
to recognize restoration projects, and
not to understand their place in human-
constructed environments. This can make
can oten be driven more by a desire
to establish historical conditions than to
instate a biological system that unctions
under current conditions. What orm
should a restoration project take?
Ecologists typically view nature as a model

the process o construction, maintenance,
and even the locations o many o these
projects are ar rom natural. Natural istic
design approaches may also be more
expensive. Many building materials are

The Historic Forest: an Ecological and
Cultural Conundrum
The 300-acre Historic Forest is composed
primarily o single-species groves
(eucalyptus trees, Monterey cypress,
and Monterey pine) planted in regiments
across the landscape. Today, this planted
orest has matured, creating a dense
canopy that inhibits the emergence o
understory vegetation.
A deeper understanding o the orest and its
history illustrates how it has been shaped
by preceding land management decisions
and historical preservation. New ecological
ideas are being explored and tested to
possibly retrot or enhance the Historic
Forest or improved ecosystem unction.
Major William A. Jones Plan or the
Cultivation o Trees upon the Presidio
Reservation (1883), one o the largest
landscape plans o its time, called or
thousands o eucalyptus, pine, andcypress groves to be planted in rows,

plantings were envisioned to accentuate
the posts size and create a clear visual
distinction rom the surrounding city. The

original vision never ully materialized.
Forest plantings were initiated on the
dunes in the 1890s and mostly completed
by 1906, but continued sporadically
over a 55-year period, ending in the early
1940s. The straight rows o trees planted
in groups have created a unique orest
o mature single-species growth with
a high canopy and minimal understory.
This planted orest is celebrated as a
cultural symbol o the Presidios military
past. The high canopy, which allows
extended views across the shaded orest
loor, is championed by pedestrians,
recreationists, and dog-walkers. Even
some environmentalists view the orest
as a special place, a green respite within
the city. The National Historic Landmark
District designation granted to the Presidio
in 1996 solidied the Historic Forest as a
key landscape eature.
Despite the intentions o the Army and
Major Jones to use the orest plantation as
an environmental management technique,
many ecologists and environmentalists
currently argue that the orest is a symbol
o an invasive and manipulated Presidio
landscape that has supplanted the native
habitats. They note that any ecological
value the Historic Forest might have is
diminished by the act that only 10 percent
o the Presidios land supports the native
plant community that existed prior to
landscape modications. Over time, the
planting o non-native, limited-species tree
stands has resulted in signicant native
habitat and wildlie losses. Consequently,
many ecologists and environmentalists are
calling or portions o the Historic Forest to
be modied and converted into a
native landscape.
Nonetheless, the existing orest does
have some signicant ecological merit,
as it supports nearly 200 bird species and
contains a ew mixed tree species stands.
It is also notable that a signicant portion
o public users view this orest as a natural
respite in the city. This perception, and the
value that people nd within the woods as
a natural amenity, gives the Historic Forestinherent worth regardless o its actual value
as an ecosystem.
A 2001 vegetation management plan called
or changes to portions o the Forest by
removing some mature stands in danger
o wind-all and replacing the stands with
native, diverse plantings (see Fig. 2-10).
Further discussion o reorestation can
be ound in the Restoration Ecology
section o Chapter 3.

Interdisciplinary
Collaboration
EDAW teamed with the Presidio
Trust in a collaborative workshop to
repurpose the Presidios Fort Scott Creek
Area. The interdisciplinar y exchange
brought together EDAW's technical
experts with multiple stakeholders
working with and/or within the
Presidio Trust. As the diagram (Fig.
2-11) illustrates, there were several
exchanges required or successul
collaboration. First, the EDAW team
members needed to communicate
internally; second, the Presidio Trust
and EDAW team needed to work
together; and third, this larger team
needed to understand and respond
to stakeholder viewpoints and concerns.
The EDAW team built an initial
relationship with the Presidio Trust
through conerence calls and planning.
Together, EDAW and the Presidio Trust
devised the workshop schedule. This
initial collaboration led to discussingand highlighting shared goals. The
resultant shared goals helped build
trust, and led to an exchange o critical
inormation. The Presidio Trust provided
guidance throughout the event, helping to
orient the team and enhance the results.
The week-long workshop was
organized as an ongoing dialogue
between the designers and ecologists.
Facilitating exchange, both in planned
discussions and through inormal
interactions such as site walks, was a
key goal. We created many situations
or interdisciplinary communication,
including evening events, lunchtime
discussions, and hands-on activities
to promote dialogue and to reveal the
underlying goals and intentions o the

into alignment.
At the heart o this challenge is the
need to explore how these dierent
interests can be brought together. I n
addition to the multiple stakeholder
views, the designers and ecologists also
bring varying perspectives to the table.
To create meaningul urban spaces,
designers, ecologists, the client, and the
stakeholders need to understand that

public use, natural areas, and historic
designs need not be physically separate.
In act, the meaning o space intensies
as its layers o use increase. An urban
park is the apotheosis o this synergy.
The Presidio is exactly this type o space,
combining ecological systems o plants,
water cycles, and nutrient exchanges with
the human ramework o walking trails,
historic preservation, community gardens,
playing elds, and picnic areas.
Our hope was that collaboration between
stakeholders could be used as a catalyst
or integrating the public use o natural
areas into an urbanized setting.
The Presidio Trusts practice o planning and
design strives to balance the competing
interests o public use and access (P),
natural areas/restoration needs (N), and
historical preservation (H). (see Fig.
2-12). The se three types o land uses are
essential to the Presidio Trusts mission, its
cultural identity, and its role as a public
parkland within an urban area. Each o
these drivers has shaped the Presidio up
until the present day.

stakeholders that one might nd within
each category. This variety o users
presents a primary challenge in reaching
decisions on planning, programming, and

Intent
Our goal or the site visit was to interpret
the land rom an integrated ecological
and design angle. The team intended to
discuss and plan the visit thoroughly with
an eort to integrate typical site analysis
strategies that ecologists use with designer
approaches. A brie initial slide show on
land-use history and site conditions helped
establish a shared baseline understanding.
A visit to key locations across the Presidio
allowed the team to experience the
landscape and assess its ecological
unctioning. We planned to document the
site together through mapping and analysis.
Intent
The convening o stakeholders was
intended as a rapid outreach approach to
understand constraints, learn about site
uses, and discuss potential opportunities.
The team hoped to appreciate the
stakeholders' multiple viewpoints and
develop a deeper understanding o
stakeholder needs. By the end o the
day, we planned to generate a list o
stakeholder goals and objectives or Fort
Scott Creek and synthesize these goals
into an overall approach.

Day 1
Site Visit
Intent
We planned to bring in a large group o
stakeholders or a second day to conduct
a ull-day charrette, with the intention o
bringing conficting desires to the surace.
The goal o this session was to begin to
translate goals and visions into a physical
layout plan. Ideally, we would develop
some alternative approaches and acilitate
discussion to identiy key problems and
their potential.
Day 3
Design Charrette
Intent
The day was planned as a collaborative
work session to clariy a ew options
and then rene the vision concepts
into a proposal or Fort Scott Creek and
Fort Scott. Beorehand, we discussed
ways o working together to develop a
process to complete the work tasks.
The goal o the process was to acilitate
the development o a nal presentation
to the public that would capture the
experiences o the week, laying out the
solutions and compromises.

strategies. We attempted to get eedback
rom the invited guests on how they elt
the process went and the quality o the
outcomes produced. We tried to evaluate
how the public stakeholders responded
to the nal product o a collaborative
process. We wanted to hear concerns
expressed and alternative ideas oered.

Lessons Learned
rom the Presidio
The Presidio workshop yielded many
lessons about the viability o combining
ecology, public use, and history through
design. The process also exposed
the multitude o planning and design
challenges in addressing the Historic
Forest, community gardens, and
ecological restoration activities. Adeeper exploration o these challenges,
presented in the ollowing pages o
analysis, reveals a number o themes
infuencing planning and design at the
Presidio. These included: conficting
and incompatible land uses; precedent
land management decisions; evolving
ecological and historical disciplinary
approaches; and various preservation and
conservation approaches. The ollowing
pages aim to introduce the Presidio
site studied within the C + P Initiative,
and to educate ecology and design
practitioners about the challenges
o moving toward consensus or land
planning in an urban park.

Outcome
Participants learned about the larger vision
o the Presidio and saw examples o other
projects that had successully navigated
politics and ound solutions through
compromise. The tour o the Presidio
was especially useul because questions
came rom space ecological and designperspectives, so the team became more
educated as a whole.
The visit to Fort Scott Creek allowed us to
amiliarize ourselves with the site and to
document it through hand mapping and GIS.
The high points were the moments when
an ecologist and designer walked together
and discussed ideas rom both perspectives
about that particular area.
While executing the site visit with a mix o
ecologists and designers generated trust
across disciplines, the site visit needed
more direction, with specic activities
to acilitate communication. An early
concept that we explored in depth was
to develop a physical intervention as an
artistic gesture and scientic experiment
(see Fig. 2-17). For example. we discussed
ways o mapping ecology physically on the
landscape to make it more visible.
Objective
Our goal was to work collaboratively,
utilizing skills as designers and ecologists to
analyze the Presidio and to experience and
interpret the Fort Scott Creek project area.
Process
The group toured the Presidio with multipleexperts to understand existing land use
patterns and to see rsthand how the
Presidio Trust has been i mplementing
its missions o land stewardship. Michael
Boland and Allison Stone o the Presidio
Trust led the tour, which included a number
o destinations exhibiting site restoration or
native habitats. These included Inspiration
Point; the Mountain Lake restoration;
multiple neighborhoods; coastal blus;
a plant nursery; historic and community
gardens; Fort Scott; and the Creek. Other
participants included Betty Young, Mark Frey,
Laura Castellini, Damien Raa, Barb Co;
Johna Maeck, and Jean Koch.
Ater a long debate, we voted to rely on our
individual expertise and typical practices as
designers and ecologists. This diered rom
our original idea to pair an ecologist with a
designer in the eld and encourage dialogue
on-site. The idea was that using the methods
we would employ on any other project would
give the client the best results.

Objective
The goal o the stakeholder meetings
was to learn about the various visions
or the Fort Scott area and creek. This
was achieved through a process o public
engagement that ocused on stewardship
and sustainability. The team interacted
with the volunteer groups, historicpreservationists, restoration ecologists,
the maintenance and operations group,
and the architects working on the
sustainability building or the cen ter.
Process
The EDAW/Presidio Trust team worked
together to establish a clear workshop
schedule (Fig. 2-14).
The Presidio Trust organized stakeholder
groups or the EDAW team to intervi ew.
Each group met independently with
the EDAW team, allowing the team to
eciently and concisely understand
the concerns and desires expressed byeach group (Fig. 2-14). Key players rom
each stakeholder group were invited to
participate in a wrap-up strategy session
to develop goals and objectives.
Outcome
The stakeholder meetings were a
ormative part o the workshop. The
perspectives shared during the meetings
exposed the dynamic, complex, and
pluralistic nature o the Presidio. The all-
day dialogue proved to be a tremendous
success or both the EDAW team and thePresidio. The EDAW Team built trust with
stakeholder groups through the dialogue
process, and claried a working set o
goals and objectives.
In part, this exercise was valuable or
the stakeholder groups and Presidio
Trust because the workshop brought
some stakeholders together or the
rst time. This event gave them an
opportunity to learn more about each
other, to recognize opposing positions,
and to conceive o ways to move
orward in alignment.
The multidisciplinary discussion steeredthe energy o all participants toward a
common vision. The goals articulated and
agreed to by the stakeholder groups built
on the Presidio Trusts mission: to balance
historic preservation with sustained
ecological systems while ostering public
engagement. It is this attempt to satisy
