Lecture 9 GEOG3320 – Management of Wilderness Environments 2
Wilderness “A wilderness, in contrast with those areas where
man and his own works dominate the landscape, is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain.” US Wilderness Act (1964)
Lecture 9 GEOG3320 – Management of Wilderness Environments 3
“For some, wildernesses are desolate places outside of the humanized realm, either to be avoided or brought under some kind of human dominion, and for others, they are places to practice humility, experience a certain vulnerability and acknowledge the creative and even destructive powers of the natural world.” Peter Taylor in Beyond Conservation: a wildland strategy (2005, p.8)
Lecture 9 GEOG3320 – Management of Wilderness Environments 4
Self-willed land
“True wilderness is a land that has supreme naturalness and is free of any human control. It is a self-willed land because plants and animals can thrive there, in their own unfettered communities.” (Mark Fisher)
Lecture 9 GEOG3320 – Management of Wilderness Environments 5
Wilderness Britain? “Those regions or locations that are
remote, devoid of human features and with natural or near-natural ecosystems.
…wilderness is just one extreme on a continuum - a kind of sliding scale of human modification of the environment - from the 100% artificial buildings of the city centre through to the pristine nature found in remote locations. The position along this wilderness continuum at which wilderness occurs has perhaps more to do with individual perceptions than it does with ecological conditions.”
Carver (1996)
Lecture 9 GEOG3320 – Management of Wilderness Environments 6
Wild land
“Wildland in Scotland is relatively remote and inaccessible, not noticeably affected by contemporary human activity, and offering high-quality opportunities to escape from the pressures of everyday living and to find spiritual and physical refreshment”. NTS (2002)
Lecture 9 GEOG3320 – Management of Wilderness Environments 7
Question
What are the attributes which contribute to or detract from a
wildland experience
(i.e. “enhancers and detractors”)?
Lecture 9 GEOG3320 – Management of Wilderness Environments 8
Re-wilding
“In Britain, an ethos of wildland is emerging in which human intervention is minimal and natural processes are respected.” (Peter Taylor, 2005, p.14)
Lecture 9 GEOG3320 – Management of Wilderness Environments 9
“Self-willed land for its own sake will only exist in Britain if land is held inalienably in the public good and that legislation exists to define its natural character, and thus the limits to human intervention.” (Mark Fisher)
Lecture 9 GEOG3320 – Management of Wilderness Environments 10
Approaches to re-wilding “Letting go“
- if a landscape is left unmanaged for a long enough period, nature will take over and produce its own entirely natural landscape
- may not necessarily be the same landscape that existed before human settlement, but it will be natural
“Wild by design“- we may need to actively 'design' wild
landscapes by assisting the regeneration of native species to recreate a more natural looking landscape
- limited economic activity in the form of low intensity grazing and recreation is still possible and indeed desirable
From protectionism to strategic habitat creation
Lecture 9 GEOG3320 – Management of Wilderness Environments 11
Trees for Life
Vision: a large core area in the north-central Highlands of Scotland- Ecological principles – “Nature knows best”
- practical demonstration realities of ecological restoration
- including:• mix of planting programmes• keeping out the deer• natural regeneration• re-introduction of native mammals
Guest Lecture: Alan Watson Featherstone
Lecture 9 GEOG3320 – Management of Wilderness Environments 12
The Carrifran Wildwood
Vision: “…to re-create in the Southern Uplands of Scotland an extensive tract of mainly forested wilderness, with most of the rich diversity of native species present in the area before human activities became dominant.”- past conditions informing future
natural- no commercial exploitation- careful management of human
impacts• open access to all• inspirational and an educational
resource
Lecture 9 GEOG3320 – Management of Wilderness Environments 13
The Carrifran wildwood (cont’d) The site:
- eastern limit of Dumfries & Galloway in the Moffat Hills, Scottish Borders
- approx. 1600 acres (650 hectares)
- overgrazed sheepwalk, grouse moor and sitka spruce plantation
- relict broadleaf trees in steep gullies (cleuchs)
Lecture 9 GEOG3320 – Management of Wilderness Environments 14
Existing designations:- Regional Scenic Area under the local
authority Structure Plan
- Environmentally Sensitive Area (ESA)
- Moffat Hills Grade 1 Nature Conservation Review Site (NCC 1991)
- Moffat Hills Site of Special Scientific Interest
• original SSSI notification was in 1956 and re-notifications have taken place in 1972, 1974 and 1988
- candidate Special Area of Conservation (SAC) under European Union legislation.
The Carrifran wildwood (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 15
History:- Project conceived by local grassroots
community action in early 1990s with a simple vision to create a near-natural woodland landscape where “there would be a chance – in years to come – of losing oneself in the woods”
- Money to purchase raised by private subscription (£450k) and charitable trusts (£150k) with support from JMT and SNH
- Purchased in 2000 and 30,000 trees planted
The Carrifran wildwood (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 16
Ethos:- maximise the role of natural processes –
minimise use of physical and chemical intervention… make the wildwood feel wild
- aim to create a functioning ecosystem that can evolve over centuries and where human influence will gradually decrease as nature takes over
• side-stepped ongoing debate on what is natural in favour of positive action
• maintain high level of volunteer participation through volunteer days and boundary warden scheme
• nature ultimately in charge, though no room for re-introductions or large herbivores or predators
The Carrifran wildwood (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 17
Scientific basis:- strong links with academics and
professional foresters• learn from experience elsewhere• discussion on what trees/shrubs appropriate
for establishment according to pollen record, NVC class and ESC analysis
• helped apply for WGS funding
- seed collection by volunteers from local sources within ancient woodland to ensure provenance
- planting patterns sensitive to habitat niche and landscape
The Carrifran wildwood (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 18
Unplanted for natural regeneration
Small enclosures planted as seed source for regeneration of montane scrub
Upland oak-birch woodland (Type W17) with Rowan, Holly, Hazel, Juniper and Shrub Willows
Upland oak-birch woodland (Type W11) with Rowan, Holly, Aspen, Hazel, Juniper and Shrub Willows
Juniper woodland (Type W19) with Birch, Rowan and Scots Pine
Upland broadleaved woodland (Types W7/9) with Birch, Ash, Rowan, Oak, Holly, Wych Elm, Birc Cherry, Alder, Aspen, Hwathorn, Blackthorn, Guelder Rose, Elder, Roses and Willow
Birch woodland (Type W4) with Alder and Willows
Lecture 9 GEOG3320 – Management of Wilderness Environments 20
Problems and challenges:- need to treat botanically rich flushes and rare
montane plants carefully
- avoid planting around archaeological features
- avoid obscuring view near to public highway
- removal of feral goats
- accidental loss of 10,000 recently planted trees to muirburn from adjacent farm
- problems establishing young trees in face of natural processes
• competition by grass and bracken• browsing by deer, voles, hares and stray stock• need to fence and maintain enclosures• need for initial herbicide treatment and vole
guards• need for some culling of deer
The Carrifran wildwood (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 21
Wild Ennerdale Vision: “to allow the
evolution of Ennerdale as a wild valley for the benefit of people relying more on natural processes to shape its landscape and ecology”- not about re-creating a
past landscape, but about allowing the character of the valley to develop into the future
- no fixed ‘end point’
Lecture 9 GEOG3320 – Management of Wilderness Environments 22
Wild Ennerdale (cont’d)
The site:- northwest corner of Lake District National Park
- 4,500 hectares in ranging 770m in altitude
- Dramatic scenery: Pillar (892m), the River Liza “one of the most wild and geomorphologically natural rivers in England” and Ennerdale Water SSSI
- Farming, commercial forestry and water supply
Lecture 9 GEOG3320 – Management of Wilderness Environments 24
Existing designations:- Ennerdale Water SSSI
• Designated for lakeshore habitats and flora & fauna (inc. Arctic Char)
- SSSI along southern watershed (Caw Fell, Haycock, Scoat Fell, Pillar, Kirk Fell and Great Gable)
- candidate SAC• designated one of the best examples of
altitudinal succession in England
Wild Ennerdale (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 25
History:- land owned by Forestry Commission, National
Trust and United Utilities• 1990 FC and NT agreement on need for shared vision
for the valley• 2002 FC and NT joined by UU to form Wild Ennerdale
partnership• supported with English Nature funding
- since 2002• period of information gathering• developing stewardship plan
Wild Ennerdale (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 26
Ethos:- two key philosophies:
• biocentric - encourage natural forces in long-term development of the valley to shape distribution, extent and variety of habitats and ecosystems
• anthropocentric – recognises that wildness is a human experience and so is need to increase sense of wildness by limiting visual impact of people at same time as encouraging involvement
- looking forward, not back
- reduce detracting features associated mainly with commercial forestry
Wild Ennerdale (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 27
Scientific basis:- set up advisory group
- information gathering• full NVC survey completed 2004• Historic Landscape Survey completed 2003• GIS extensively used to map valley including
spatial distribution of wild and detracting features and its use to help understand the ‘sense of wildness’ throughout the valley
- involve universities and students
- information used to draw up extensive stewardship plans for the valley
Wild Ennerdale (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 29
Problems and challenges:- commercial forestry
• mixed views – both ‘wild’ and detractor• careful management (thinning/planting) vs
dense spruce and self-seeded re-generation
Wild Ennerdale (cont’d)
Lecture 9 GEOG3320 – Management of Wilderness Environments 30
Problems and challenges:- Need for natural grazing patterns and move
away from grazing based on ownership, fenced stock and subsidies and towards large dynamic disturbance by cattle
• break up mats of dead litter and create pathways through tall, dense vegetation and promote varied mosaic
• small herd of Galloways introduced in 2006• monitoring by vegetation and photo surveys
