CITY OF SMYRNA TREE CANOPY COVER STUDY FINAL REPORT OF RESULTS
February 5, 2010
1
INTRODUCTION
In November 2009, as part of the city’s 2009 Urban and Community Forestry Grant, the City of
Smyrna conducted a measurement of its existing tree canopy and other land cover within the
city limits. The study was sponsored by the City of Smyrna and the Smyrna Tree Board and was
completed with the support of Ms. Sharon Harper, horticulture and agriculture teacher in the
Science Department at Campbell High School, and 60 of her students who analyzed and
measured the land cover. The study was coordinated by Connie Head, Consulting Urban
Forester with Technical Forestry Services, who also prepared this report.
The 60 student volunteers and Ms. Harper
collectively dedicated more than 420
hours, first in a 1-hour classroom
orientation exercise on Monday,
November 16 and then in a 6-hour analysis
and measurement session at the Smyrna
Community Center on November 18.
Additionally, Smyrna Tree Board volunteer
members Michael Streger, Gretchen
Musser, Carl Valenzano, and Mary Long
spent several hours preparing for the study and a total of 15.5 hours on the day of the study
guiding the students.
METHODOLOGY
The study was completed using aerial photography flown in February 2009. Printed aerial
photographs were produced by Mr. Clarence Blalock, GIS Manager in the Community
Development Department of the city of Smyrna. Mr. Blalock, with the assistance of the city’s
GIS intern April Herrett, designed and printed the 39 aerial photographs, each 18 by 18 inches
in size. The photographs were printed at a scale of 1 inch on the photograph equal to 300 feet
on the ground. Figure 1 shows an index map with the layout of the 39 photographs or “tiles”.
They are arranged in rows A through I, and numbered A1 beginning at the upper left to I1
located at the bottom.

Each photograph was covered with a grid of yellow dots, one-sixteenth inch in diameter and
placed one-half inch apart, equivalent to 150 feet on the ground, as shown in Figure 2. These
dots essentially represent measurement plots. The students, working in teams of two (2),

identified the land cover type beneath each yellow dot (within each plot), color coded the dot
directly on the photograph, then counted the dots by category, and finally recorded the results
on tally sheets. Each photograph was reviewed and the dots re-counted at least one (1)
additional time by another team of students. Then, the consultant reviewed, re-coded in some

cases, and recounted all dots on all photographs to ensure the consistency of the categorization
and accuracy of the dot counts.
Land cover was divided into five (5) categories, as described below.
Tree canopy. This category includes all trees, whether hardwoods or conifers, deciduous or
evergreen, and of any size as long as they were distinguishable on the photographs. Since the
land was photographed in February, the majority of the hardwood trees were without leaves,
but hardwoods were still recognizable. Dots that fell on tree shadows that projected beyond
the tree’s canopy were not counted as tree canopy cover, but were instead categorized
according to the land cover type beneath the shadow. Tree canopies intercept precipitation
and slowly release it, increasing penetration of water into the soil and decreasing overland
flow. Tree canopies also cool the air temperature through evaporative cooling (evapo-
transpiration) of water from their leaves, and reduce surface temperatures by shading them.
Trees improve air and water quality, sequester carbon, and reduce heating and cooling costs.
They contribute to a community’s economic base by enhancing quality of life and increasing
property values. They also provide recreational opportunities and wildlife food and habitat.
Their functions and benefits are many.
Other vegetation. Shrubs, turf grass, vines (such as kudzu), and herbaceous vegetation that is
not covered by tree canopy was categorized as other vegetation. This other vegetation occurs
on pasture land, in vacant lots, on cut-over sites, on lawns, and along roads and in road
medians. Very small trees that were not recognizable as trees and did not project a shadow
were also included in this category. This other vegetation intercepts some precipitation, but
overland flow is increased on these surfaces as compared to tree canopy. And similarly this
other vegetation helps to cool surface air temperatures, but to a considerably lesser extent
than trees. The more the layering and complexity, the greater the texture, and the greater the
total surface area of the vegetation, the more benefits it provides.
Impervious surfaces. Any surface that is impervious to water, such as concrete, asphalt, and
metal, and any structure covered with such surfaces, such as streets, parking lots, driveways,
sidewalks and buildings, was categorized as impervious surface. Impervious surfaces that are
directly covered by tree canopy were categorized as tree canopy, however. All of the
impervious surfaces and structures shed precipitation, increasing overland water flow and
potentially flooding. They also absorb radiant heat and increase surface air temperatures.
However, if theses surfaces are covered with tree canopy, these negative attributes will be
somewhat reduced.

Bare soil and gravel. This category includes areas where the soil was exposed or gravel was
present, such as on graded land, unpaved roads, some parking areas, in quarries, and along
railroad tracks. While water does penetrate these surfaces to some extent, the more compact
the surface the more similar it becomes to paved or impervious surfaces.
Water. Open water was found on the photographs in ponds, creeks, marshes, and swimming
pools.
RESULTS
There were 18,790 dots within the city limits and all were categorized, color coded, and
counted. Each dot represents an area of 22,500 square feet (150 feet by 150 feet) or
approximately .5165 acre. The total area of the city, based upon the number of dots that fell
within the city limits, is estimated to be 15.165 square miles, equivalent to approximately 9,706
acres. This total area estimate is within .005 square mile of the GIS Manager’s estimate of
15.17 square miles.
As shown in the summary on the right and by the raw data
in Table 1, tree canopy covers 39 percent of the land
within the city limits of Smyrna. Other vegetation covers
25.2 percent. Impervious surfaces cover 34.4 percent of
the city. Bare soil or gravel and water each cover less than
1 percent of the area within the city.
The amounts of tree canopy cover and impervious surfaces greater than 50 percent by map are
highlighted in bold type and shading in Table 1. There are seven (7) aerial photographs with 50
percent or greater tree canopy cover, and nine (9) aerial photographs with 50 percent or
greater impervious surface.

The Natural Resources Spatial Analysis Laboratory (NARSAL) in the College of Agricultural and
Environmental Sciences at the University of Georgia, under the direction of Dr. Liz Kramer, has
measured Georgia land use trends using 1991, 2001, and 2005 satellite imagery and aerial
photography1. The data is available by county and metropolitan statistical area. While the data
developed using satellite imagery cannot be directly compared to the results from this study
using aerial photography, the findings from each study appear to support the findings from the
other.
The NARSAL data for Cobb County shows the following trends:
P In 1991 tree canopy in Cobb County was 53 percent and decreased to 47 percent in
2001 and to 44 percent in 2005, a loss of 19 percent of total acres of tree cover over the
period. Tree canopy cover in Smyrna in 2009 is 39 percent. The Smyrna results are
consistent with this downward trend in tree canopy cover across the county.
P In 1991 impervious surface was measured at 10 percent, and increased to 17 percent in
2001 and then to 21 percent in 2005, for a total increase over the period of 102 percent,
more than double. Impervious surface in Smyrna in 2009 is 34 percent. The Smyrna
results are consistent with this upward trend in impervious surface cover within the
county.

Tree canopy cover studies using the same dot grid methodology used in Smyrna have been
completed by the consultant in the last 3 years in Cartersville, Rome, and Jefferson, Georgia.
The results from those studies are as follows:
P The amount of tree canopy cover in Cartersville, Bartow County, as of February 2007
was found to be 50 percent, and the amount of impervious surface was found to be 18
percent. A total of 34,292 dots were categorized, color coded, and counted.
P The amount of tree canopy cover found in Rome, Floyd County, as of February 2008 was
49 percent. The amount of impervious surface was 23 percent. A total of 38,401 dots
were coded and counted.
P The amount of tree canopy cover found in Jefferson, Jackson County, as of February
2009 was 56 percent, and the amount of impervious surface was 11 percent. A total of
26,990 dots were coded and counted.
Compared to these communities, Smyrna’s tree canopy cover of 39 percent is considerably
lower and the impervious surface cover of 34 percent is considerably higher.
DISCUSSION
In general the greatest amount of tree canopy cover in Smyrna is found on undeveloped land,
in rural areas, and in older residential neighborhoods. The least amount of tree canopy is found
in commercial districts, especially in parking lots, on industrial sites, and in new residential
subdivisions, where significant amounts of trees are removed and replaced with impervious
surfaces and turf. Table 2 provides information on the general land use and zoning within the
area covered by each photograph. The land use descriptions were developed from looking
both at the photographs themselves, and a zoning map for the city of Smyrna.
Older, traditional neighborhoods contain an abundance of trees, which partially cover the
houses, driveways, and streets. In new residential developments, significant tree cover is
lacking and much of the land cover is other vegetation, primarily turf as well as impervious
surfaces in the form of non-canopied streets, houses, garages, and driveways.

The table shows that except for photograph A5, the areas with the highest tree canopy cover
are single-family residential areas that also contain a substantial amount of wooded areas. The
development that has occurred within the photograph A5 area is less dense and there are
substantial wooded areas that exist within the developments. The areas with the greatest
amount of impervious surface, and often the lowest amounts of tree canopy, are general
commercial and industrial areas, and in some cases include multi-family residential use.
Where tree canopy covers pavement, summer temperatures are lower, the urban heat island
effect is reduced, the production of ground level ozone is reduced, and pavement life is
extended. The addition of more trees, especially near and throughout the impervious surfaces,
will further increase these benefits as tree canopies grow and extend over parking lot
pavement, buildings, walkways, and roadways. It should be noted that the amount of
impervious surface within the city is in fact greater than the 34.4 percent found in this study.
Some of the impervious surface is covered with tree canopy and counted as tree canopy.
Increases in tree canopy cover will occur as young and newly planted trees grow and can be
identified on the aerial photography. This growth will occur in new developments where trees
have been planted to meet tree ordinance requirements. It will occur in abandoned fields and

pastures where in-growth of trees takes place where mowing is eliminated. It will occur as
trees in general grow to reach maturity throughout the city. It will occur as the vacant street
tree planting sites identified in the 2008 and subsequent street and park tree inventories are
filled.
Decreases in tree canopy cover will take place where trees are removed and replaced with
substantially fewer trees, as is the case in most new developments. Decreases in tree canopy
cover will also take place as Smyrna’s aging large canopy trees decline and are removed along
street rights-of-way, in parks, in residential yards, and on commercial sites. If these trees are
not quickly replaced with an equivalent amount of large tree canopy, Smyrna’s tree canopy
cover in the future will be considerably less than it is today.
CONCLUSIONS
The amount of tree canopy cover found within Smyrna as of February 2009 is an alarmingly low
39 percent. It is below the 40 percent minimum recommended by American Forests, a non-
profit tree advocacy group that has been a pioneer in the measurement of tree canopy and its
benefits. Equally alarming is the amount of impervious surface found by the study, 34.4
percent. More than one-third of the area of the city is impervious surface and is not available
as rooting space for trees or any other vegetation.
Adding tree canopy cover in Smyrna and reducing the amount of exposed (not covered by tree
canopy) impervious surfaces, is critical. A policy of no net loss should be adopted immediately,
and then a long-term tree canopy cover percent goal should be established. Without a no net
loss policy and without the active conservation, maintenance, and replacement of trees in the
city, a loss of tree canopy cover will quickly occur. Every square foot of tree canopy cover that is
removed must be replaced for the current amount of tree canopy cover to be maintained.
The study results also show that tree canopy cover in Smyrna is not evenly distributed. It is
generally abundant on undeveloped land and in older neighborhoods, where impervious
surfaces are absent or limited in extent. Tree canopy is generally lacking in commercial districts
and on industrial properties, where impervious surfaces dominate the land cover, and in new
subdivisions where most trees are removed and replacement is minimal. A better distribution
of tree canopy is needed to take advantage of the environmental functions of trees and to
realize their many economic and social benefits.

RECOMMENDATIONS
P Using the current study results as a baseline, future measurements using aerial
photography and the same methodology should be done to monitor changes in tree canopy
cover and impervious surfaces. Using the same methodology from year to year will produce
reliable information on the trends in tree canopy and impervious surface cover, and will
provide feedback on the effectiveness of tree management policies and tree regulations.
P Adopt a baseline policy of no net loss of tree canopy cover to maintain a minimum tree
cover of 39 percent. Strategies for achieving no net loss should include tree conservation,
tree protection, proper and routine tree maintenance, and replacement tree plantings.
Offset any losses in tree canopy that occur on an individual property, along each street,
within each neighborhood, and throughout each zoning district.
P Hire an arborist to monitor tree canopy cover change within the city and develop a
comprehensive community tree management program to increase tree canopy cover. The
management program should focus on the maintenance and planting of city trees, promote
the conservation of existing trees through education and outreach on the functions and
benefits of trees, and engage all community partners in the planting of new trees wherever
vacant planting sites exist.
P The city should begin the process of filling vacant street tree planting sites identified in the
2008 tree inventory, focusing on the planting of sites suitable for large canopy trees. There
were 172 vacant sites identified that are suitable for large canopy trees, and another 40
sites identified that are suitable for planting medium canopy trees.
P Assign the responsibility of monitoring tree canopy cover change to the Smyrna Tree Board.
Monitoring will include additional tree canopy cover measurements conducted every 3
years using the same methodology used in the 2009 study.
P Assign the responsibility for tracking tree canopy cover loss and arranging for tree canopy
replacement on city property to the Public Works Director for trees on street rights-of-way
and around city facilities, and to the Director of the Parks & Recreation Department for
trees within parks. They should summarize the amount of tree canopy cover loss and
replacement as number of square feet of canopy, on property under their control on an
annual basis.

P Assign the responsibility for tracking tree canopy cover loss and replacement on new
private property developments to the Community Development Director and City Planner,
who should summarize the amount in square feet of loss and replacement on an annual
basis.
P Enforce the tree ordinance requirements for tree density, tree conservation and
replacement tree plantings. Review the tree ordinance periodically and visit completed
developments to determine if the tree ordinance requirements are resulting in their
intended outcome and adequate tree canopy cover on development sites.
P Focus tree planting in areas where tree canopy is needed over impervious surfaces. These
areas include street rights-of-way and medians, parking lots, and around buildings. Adopt a
policy of 50 percent coverage of all parking lots.
P Increase the amount of tree canopy cover to a maximum of 50 percent. This will require an
aggressive annual tree planting program by the city, the business community, the
development community, and residents. To increase tree canopy cover 11 percent overall,
from the current 39 percent to 50 percent, the community will have to plant enough trees
to cover an additional 1.67 square miles or 46,490,020 square feet. If each tree provides an
average of 2,000 square feet of canopy at maturity (a crown width of approximately 50
feet) then an additional 23,245 trees must be planted. To increase tree canopy cover by
only 6 percent to 45 percent, the community will have to plant an additional 12,687 large
canopy trees. These trees are in addition to those that must be planted for no net loss to
replace existing trees that are removed.
P Plant large maturing, canopy trees wherever and whenever possible in lieu of planting
small, ornamental trees.
P Engage all partners in the community in maintaining and increasing tree canopy cover by
conserving natural forested areas, protecting trees, properly maintaining existing trees, and
planting additional trees. Develop education and outreach programs to support
community-wide tree conservation and planting efforts.
P Regardless of the tree canopy cover target the city chooses, an aggressive, ongoing and
long-term annual tree planting program should be developed immediately to ensure that
the city maintains a healthy level of tree canopy cover throughout the city for current and
future generations of citizens.
