In preparation for the strategic session with Council on Monday, October 3rd, 2011 please find
the following report attached:
• Kitchener's Urban Forest — A New Paradigm
Urban Forest Sustainability & Best Management Practices
The goal of this session is to inform Council about Kitchener's urban forest and the important
role it plays in a healthy, economically vibrant community. While there has been a growing
recognition of the importance of Kitchener's urban forest, the urban forest is still not given the
same budget requirements as other strategic assets.
In the spring of 2011 staff presented information on a sustainable urban forest to Kitchener's
Environmental Committee. Staff have also been working on a number of projects including:
Emerald Ash Borer, Street & Park Inventory, Pilot Management Plans supported by LEAF.
Recognizing the work being done, and its strategic connections it was felt this issue should be
brought to Council. In presenting this information at a Strategic Council Session staff are looking
for feedback on the information and urban forestry strategies presented.
On October 3rd staff will make a PowerPoint Presentation on the key themes, including:
• Economic, environmental and social benefits of the urban forest
• Urban forest management and best management practices
• Community support & engagement
• Emerald Ash Borer
• Urban Forest Budgets
The presentation by staff will be followed by a discussion of the issues.

Urban Forest Sustainability & Best Management Practices
Introduction
The goal of this session is to inform Council about Kitchener's urban forest and the important role it
plays in a healthy, economically vibrant community. While there has been a growing recognition of
the importance of Kitchener's urban forest, the urban forest is still not given the same budget require-
ments as other strategic assets.
In the spring of 2011 staff presented information on a sustainable urban forest to Kitchener's Envi-
ronmental Committee. Staff have also been working on a number of projects including: Emerald Ash
Borer, Street & Park Inventories, and Pilot Management Plans supported by LEAF. Recognizing the
work being done, and its strategic connections it was felt this issue should be brought to Council. In
presenting this information at a Strategic Council Session staff are looking for feedback on the urban
forestry strategies being presented.
Objectives
The objectives of this report are to make Council aware of:
the urban forest and the economic, environmental and social benefits it provides
the need to manage the urban forest sustainably using Best Management Practices
the community support for the urban forest
the City's street trees and natural areas
the City's urban forestry issues for street & park trees, and natural areas
Corporate Strategic Connections
The importance of Kitchener's urban forest is recognized in a number of the City's strategic initiatives,
including:
• Operations Business Plan - Service Priorities 2012 - 2014(Draft) identifies the development of a
sustainable urban forest plan in 2013, and implementation in 2014.
• City Asset Management Project - urban forest is one of 12 recognized city assets
• Parks Strategic Plan - Natural Areas Theme
• Strategic Plan for the Environment
• Draft New Official Plan
Managing Kitchener's Urban Forest
Serving the community today & tomorrow
Based on outdated myths about the urban forest (e.g. tree planting is easy, once planted trees take
care of themselves, once acquired natural areas take care of themselves) and a program that is driv-
en solely by customer complaints - the current state of the management of the public urban forest is in
crisis. While customer complaints are an important part of an asset management program they should
not be the sole driver where there is a desire to maximize benefits and minimize lifecycle costs. The
lack of an asset management system that can identify high value trees, current workloads, safety
risks, and the time it takes to resolve work orders (e.g. stumping, tree removal) is a serious problem.
With the arrival of Emerald Ash Borer the existing situation will get worse.
Recognizing the economic, environmental and social services that the urban forest provides and the
community support for the urban forest, a strong argument can be made that this asset be managed
in a sustainable manner for current and future generations. Implementing Best Management Practices
based on science within an asset \ ecosystem framework is the best way to achieve a sustainable
urban forest that provides maximum benefits to the community for the least cost. Engaging the com-
munity in planning, stewardship and education are important parts of a sustainable urban forest. To
achieve this, additional investments will need to be made into specific areas to reduce long -term costs
while increasing benefits. Research shows that additional investments in the urban forest is cost ef-
fective with a greater return in benefits through longer lifecycles.
From a City wide perspective, existing and future funding must be compared to other city priorities.
Decisions made from the old paradigm where trees only provide aesthetic beauty and take care of
themselves will always place requests for the urban forest below other priorities. Without ongoing edu-
cation many people will continue to view the urban forest as an area that does not require funding.
In managing the urban forest the City has three choices: 1) continue with the status quo, in a crisis
management state, 2) reduce the asset size by stopping all new tree planting and the acquisition of
natural areas until existing budgets can manage the resource, 3) become a leader in urban forest sus -
tainabiility where the benefits of the urban forest are maximized in a cost effective manner through
the implementation of Best Management Practices and an asset \ecosystem management framework.

Community Support For The Urban Forest
Investing in the urban forest for today & tomorrow
The value and importance the community puts on services is a key consideration at the time that
budgets are considered. Previous public studies, as indicated by the City's Strategic Initiatives, iden-
tify a healthy community, economic prosperity, the environment and parks as being important. All of
these issues can be directly linked to the urban forest.
As the community becomes more concerned about the environment and a healthy City, the concern
about the urban forest also increases. Increased media attention on the urban forest, expectations
by residents that trees will be protected during road reconstruction, and public participation in Kitch-
ener's Natural Areas Program are evidence of strong community support. This support also extends
to supporting financial investments into the urban forest shown by the survey results below.
As part of the pilot street tree management plan with the Westmount Neighbourhood Association (WNA) the
community was asked a series of questions. Similar questions were also asked during a presentation to the
Auditorium Neighbourhood Association. The results of two questions that focused on investments into the
urban forest are provided below.

Urban Forestry Myths
A new way of seeing the urban forest
There are many myths and outdated ideas about trees and the urban forest. The first myth is that
trees only provide aesthetic beauty. Pages 8 -10 of this report discuss the economic, environmen-
tal and social benefits of trees. Once the true value of the urban forest is accepted, the next step is
understanding that the urban forest requires active management. Three prevailing myths, which imply
active management is not required, are presented below.
Myth #1
Soil Assessment, Planting
9 Stev —A-t,:-
Tree planting is easy
Tree planting is the first physical investment in a community's future
forest. Practices and decisions made at this time have long term
consequences and directly impact future benefits and costs of the
urban forest. Historically, the tree's roots and surrounding soil have
been ignored, yet more than 75% of all tree problems are traced
back to below ground factors. Pre - planning, soil assess ments\res-
toration, proper tree planting techniques and aftercare are critical`' , r?
elements for communities that want to develop a sustainable urban
forest.

Myth #2
Once planted trees take care of themselves
Because trees are natural it is often assumed that they require little
maintenance after planting. Tree planting is only one of many steps
(e.g. planning, soil assessment, establishment, structural pruning,
tree protection) that are required to develop a sustainable urban for-
est that maximizes community benefits over the life cycle of the tree's
life. Research shows that these additional investments into the urban
forest are cost effective over the tree's lifecycle.
Myth #3
Once protected natural areas take care of
themselves
Based on outdated ecological ideas most people believe that natural
areas within a City will take care of themselves once protected from
development. In numerous ways (e.g. climate change, fragmentation,
encroachments, development impacts, recreation) humans affect the
structure and function of these areas. To maximize the benefits from
these areas and to conserve their natural heritage features active
management and stewardship is required.

The Urban Forest
The urban forest includes all of the planted and naturally
occurring trees on public and private lands. Viewed from
above, individual trees create a forest canopy that extends
across our city. As a living organism, trees are a key part of
the larger urban ecosystem, intricately connected to the sur-
rounding living and non - living parts of the urban ecosystem.
The public urban forest includes the City's street trees, active
parkland, natural areas, and other City & government agency
forested lands. The private urban forest includes all trees on
residential, commercial, industrial and agricultural lands.
Trees in the downtown, shown in the figure to the left, are
known to improve the areas economic prosperity.
Old Residential & Park Trees

itural Areas J
Image Copyright
Trees in the old residential areas and
parks are an important part of the urban
forest. On some streets you can find
trees that are over 100 years of age.
The large lot size and relatively undis-
turbed soils are good conditions for
growing large, old trees. In some areas
(e.g. Westmount, Auditorium) the street
trees are reaching the end of their
Iifecycle. People that live in these areas
put a high value on their mature treed
canopies.
Newer residential areas being more com-
pact in size limit the physical space and
opportunities for trees, especially along
residential streets. To grow trees in these
areas greater consideration must be given
to trees during the design process and the
altered soil must be restored. Most of Kitch-
ener's largest and most significant natural
areas are found in these areas. In addition
to conserving Kitchener's Natural Heritage
they are places where the community can
experience nature in the City
Environmental Benefits
A healthy community
The environmental benefits of urban trees are significant and can be quantified using a scientific
model (iTree) developed by the United States Forest Service. Using this model municipalities can de-
termine the replacement value and the annual environmental services that the urban forest provides.
The table below shows the results for London, Oakville and Toronto which are significant. Staff plan
to carry out an iTree Eco study for Kitchener in 2012.

TREES IMPROVE AIR QUALITY BY
• absorbing gaseous pollutants (e.g. sulfur & carbon dioxide, nitrogen oxides,
ozone, smog)
• intercepting particulate matter (e.g. dust, pollen) linked to disease
(e.g. asthma, cancer)
• reducing emissions from power generation required for heating and cooling
• reducing local air temperatures through transpiration and shading
• releasing oxygen through photosynthesis
TREES MITIGATE CLIMATE CHANGE THROUGH CARBON SEQUESTRATION & STORAGE
carbon sequestration increases with large, healthy trees
TREES CONSERVE ENERGY BY
shading buildings, providing evaporative cooling, and blocking winter winds
TREES REDUCE STORMWATER RUNOFF & EROSION
by intercepting precipitation
(e.g. 7% drop in runoff for a community with 22% tree canopy)
"A large tree with a diameter of 75cm can intercept up to
ten times more air pollution than a small tree with a
diameter of 15cm"
(Every Tree Counts, A Portrait of Toronto's Urban Forest, City of Toronto)
It's All About The Big, Old Trees
Urban forest benefits
Today's Urban Forest Benefits
The benefits a community gains from its urban for-
est today comes from the biggest and oldest trees.
In contrast to other assets the value and benefits
of trees increases with age. The image to the right
shows the tree benefits increase with the size of
the tree and total leaf area, Maximizing today's
benefits requires a focus on the communities large
trees.
Tomorrow's Urban Forest Benefits
Tree planting is a long -term investment that pro-
vides economic, environmental & social benefits to
the community in the future (e.g. 40, 60, 80, 100
years).
"A large tree in the Northeast will
provide $5,870 in environmental and
other benefits over its lifetime -
a 440% return on the investment"
Trees Pay Us Back - In the Northeast Region
Forest Service, USDA
"Keeping large stature trees healthy and
functional is one of the best investments
communities can make."
(Dr. McPherson, Centre for Urban Forest Research,
ML Pacific Southwest Research Station, Forest Service, USDA)
Social Benefits
The hidden value
With close to 40 years of social research there is very strong evi-
dence that urban trees play a key role in human function, health
and well- being. Once quantified social benefits will likely exceed
the value of environmental benefits. Social benefits include:
Symptoms of Attention Deficit Hyperactivity Dis-
ADHD
order (ADHD) are reduced after children have
been in contact with treed areas.
Cognitive, social and moral development im-
Children
prove where nearby nature provides opportuni-
ties for play and experimental learning.
Community
Treed parks have higher community use, in-
Building
creasing social interaction
and creating stronger communities.
Crime Reduction
Trees lower crime rates and provide a greater
sense of safety.
People with views of trees recover faster from
Health
surgery, require less medication and have less
complications.
Local Economics
Large trees add 3 -15% to home values, and
trees increase retail sales.
Poverty
Access to nature restores attention & everyday
pressures of living in poverty.
Safe Streets
Trees reduce road stress and improve safety
(e.g slow traffic, accidents).
Stress & Mental
Trees reduce mental fatigue, and reduce the ef-
Illness
fects of mental illness.
Work & Learning
Places near nature reduce mental fatique and
improve the ability to focus.

Maximize Benefits - Minimize Costs
Through lifecycle management
Trees and the larger urban forest are a long -term investment. Decisions and actions taken today have
long -term implications. Using the principles of asset & ecosystem management - Best Management
Practices (BMP) can be developed to focus work priorities and practices.
The figure below identifies BMP that the City should implement to maximize community benefits for
the least cost. Increased investments in the urban forest (e.g. stewardship watering programs, struc-
tural pruning, tree protection) are cost effective and provide a higher return on the investment.

An Essential Asset
Kitchener's urban forest
Recognizing the economic, environmental and social benefits the urban forest provides plays a key
role in creating and maintaining a healthy community.
Identified as one of the City's twelve corporate assets, a number of steps supported by Council have
already moved the City towards a sustainable urban forest, including: Street & Park Tree Inventory,
Natural Areas Stewardship, Kitchener's Natural Areas Program, Tree Services Review, Urban For-
est Technologist & Natural Area Coordinator {FTP }, Pilot Street & Natural Area Management Plans
{LEAF }).
For the City to have a sustainable urban forest staff have developed 8 principles.
Urban Forest Sustainability Principles
1. Recognize the urban forest as an important community asset contributing to a healthy city.
2. Engage the community in the conservation, management and stewardship of the urban for-
est.
3. Maximize the economic, environmental and social benefits in a sustainable manner for a
healthy city.
4. Optimize the urban tree canopy.
5. Manage the public urban forest infrastructure within an integrated asset and ecological
framework.
6. Use emerging science, technology and practices to create a sustainable urban
forest.
7. Protect, manage and renew the public tree resource and soil habitat.
8. Conserve and restore public natural areas while providing community access.

Community Support
Connecting back to the community
Community support for the urban forest has existed since the early years of the City. Examples in-
clude the conservation of Homer Watson Park (Cressman Woods) by community leaders when it was
to be logged, and early tree plantings along City streets.
Community concern over the impact that road reconstruction would have on City and private trees led
to the development of a progressive program to protect trees during these projects. This includes the
partial funding of the City's Urban Forest Technologist position through Engineering's Capital Projects
and significant changes in how work around trees occurs.
More recently, through public demand, Operations initiated two pilot management plans funded
through LEAF with neighbourhood groups (Westmount Neighbourhood Association and Friends of
Laurentian Wetland). Other community groups have expressed an interest in seeing management
plans developed for their nieghbourhoods (Auditorium Neighbourhood Association, Friends of Lake-
side Park). Surveys of the Westmount and Auditorium Neighbourhood Associations show a very high
level (> 90 %) of interest and support for the urban forest.

Engagement, Stewardship & Education
Key parts of a sustainable urban forest
Image Copyright Emily S. Damstra
Community Stewardship
Urban forest stewardship ranges from the care of
street trees (e.g. watering, mulching) to natural
areas (e.g. tree planting, invasive species, citizen
scientist). By volunteering, residents gain satisfac-
tion, while at the same time actively participating in
the long -term management of the resource. Addi-
tionally, in many situations(e.q. watering) commu-
nity volunteers can carry out actions in a more cost
effective manner than the city can.

Community Engagement
Community engagement is the cornerstone of a
sustainable urban forest. Successful plans are those that
include public participation throughout the process, and
where residents feel their concerns and opinions are being
considered. Unless the community buys into the plan the
plan will not succeed. Recognizing that significant parts of
the urban forest are on private lands, and that much of the
public urban forest (e.g. street trees, natural areas adjacent
to rear lots) are directly adjacent to private lands, commu-
nity support and trust must be built for the community to
develop a sustainable urban forest.
Image Copyright Emily S. Damstra
Community Education
Educating the community about the urban forest in-
cludes a broad spectrum of topics ranging from how
to care for a newly planted tree to the wildlife that
lives in their local natural areas. In the image to the
left residents participate in a nature walk. Once out-
dated myths are dispelled residents can take posi-
tive action that supports a sustainable urban forest.
A Significant Threat To The Urban Forest
Emerald ash borer
Emerald Ash Borer(EAB), a quarantined tree pest, was confirmed to be present in south Kitchener in
2010. With the exception of Mountain ash, this tree pest kills all ash trees.
Based on current knowledge, it is expected that EAB will be present throughout the City within 5
years and all ash trees will be dead or dying within 10 years. Without consideration to the lost benefits
and impact on the City's existing tree canopy, the financial cost to remove and replant will be in the
millions of dollars for City lands.
Ash Density Map of Kitchener's Street Trees
The presence of ash trees along
City streets varies. This map (as
indicated by the dark blue areas)
shows the residential streets that
will be most affected by EAB.

,
In 2011 EAB was confirmed to be present along Homer
Watson Boulevard and Hwy 401. Since then it has been
found in two other locations in south Kitchener.
Local EAB Impacts
A significant impact for some residential areas
Taken in the fall of this
year, the image to the
right shows a section of
Strathcona Crescent. This
street has mature ash
trees lining both sides of
the street. Beyond the
aesthetic beauty these
trees provide important
economic, environmental
and social benefits. All
of these ash trees will be
killed by EAB.
The image to the right has
been digitally manipulated
to show what Strathcona
Crescent will look like
once EAB kills all of the
street trees. For some
residential streets the
impact will be very signifi-
cant. The density map on

areas of the City where
there will be a significant
impact.
A Significant Financial Impact

Kitchener's Tree Canopy is 22%
Tree canopy and a healthy community
Tree canopy is the layer of leaves, branches and stems of trees that cover the ground when viewed
from above. It is one method that is used to measure and increase the benefits of the urban forest.
American Forests recommends communities work towards achieving 40% tree canopy. Some munici-
palities (e.g. Oakville 40 %, Toronto 35 %) have recently set canopy goals.
% Tree Canopy by Ward (2007)
Setting canopy goals needs to be done in
conjunction with consideration to tree mor-
tality, tree size, leaf surface area, soil habitat
and BMP. It is recommended that the City
not set a canopy goal until it has completed
an iTree - Eco study. Emerald Ash Borer
and the loss of ash trees will reduce Kitch-
ener's existing tree canopy

Key Issues - City Wide
Urban forest sustainability
ASSET MANAGEMENT & CITYWORKS
Asset management ensures that benefits are maximized while
minimizing lifecycle costs. The inventory of street trees has
been completed and the park inventory is underway. A natu-
ral area database is also being developed. Another important
step is integrating this information with Cityworks.
URBAN FOREST PLANNING
Planning for Kitchener's future urban forest is required to en-
sure that goals being set are achieved. Setting canopy goals,
monitoring mortality and tree planting are key steps.
BEST MANAGEMENT PRACTICES
Best Management Practices (BMP) are the actions taken to
achieve a sustainable urban forest. BMP will require changes
to work practices (e.g. Operations, other City Departments,
Community) and require investments (e.g. structural pruning) to
maximize benefits while reducing long -term costs.
EMERALD ASH BORER (EAB)
The impact EAB will have is identified on pages 15 -17.
STEWARDSHIP He EDUCATION
Engaging the community in stewardship is a key part of a
sustainable urban forest. The high level of public participation
in Kitchener's Natural Areas Program (hikes & stewardship),
and the success of Westmount's pilot watering program show
there is strong support for these programs.
PRIVATE LANDS
Trees on private lands are a key part of the urban forest,
and in many areas it is the most significant piece. By being a
leader in urban forest sustainability the City can also encour-
age good stewardship of the private urban forest.
CAPITAL & OPERATING FUNDING
Strategic assets require adequate and consistent funding.
Through Operations Service Priorities and the Capital \Operat -
ing Budget process new funding for the urban forest will be
requested to support a sustainable urban forest.

Much more than aesthetic beauty
The planting of trees along Kitchener's
streets has been a tradition since the late
1800's. Today more than 45,000 trees line
residential streets. Like other parts of the
urban forest, street trees provide much more
than aesthetic beauty.

Inventories provide a big picture view of the
urban forest. A look at the diameter classes
of the street trees shows 74% of the trees
are less than 30cm in diameter. As these
trees grow the benefits the community
gains from the street trees increase.
Species diversity data shows that four
genus (Maple, Basswood, Ash, Ivory Silk)
account for 75% of the street trees. With
the arrival of Emerald Ash Borer, 10% of
the population will be lost in the next ten
years. Increasing diversity is a key goal of
a sustainable urban forest.
The inventory of trees in active parks (e.g.
Victoria Park) is underway and should be
completed this fall. Current numbers show
there are more than 10,000 trees, and 15%
(1,484) of those trees are ash. Once the
inventory is complete a full report of the
City's street and park trees will be pre-
pared.

Pilot Street Tree Management Plan - Westmount Neighhourhood Assoc.
With funding through LEAF, Operations is developing a pilot street tree management plan with the
Westmount Neighbourhood Association. This project came about through the neighbourhood's
concern about their declining street trees and the City's recognition of the need for a sustainable
management plan.
Currently staff are working with the community to address their concerns while also setting in place a
long term plan. Several key strategies including: master tree planting plan, stewardship and educa-
tion, tree and soil habitat conservation, structural pruning, Norway maple management and removal
plan, and an implementation plan will be addressed in the plan. This pilot project will also provide the
framework for future plans. The Auditorium Neighbourhood Association has already expressed an
interest in seeing a similar plan developed for their area.
Key Issues - Street & Park Trees
Urban forest sustainability
STREET & PARK MANAGEMENT PLANS
Operations is responsible for the long -term management of this
resource. Building on the learned experiences and success of
the Pilot Westmount NA Street Tree Management Plan a strong
cost \benefit argument can be made to implement similar plans
across the City.
LARGE STATURE TREES (LST) & SOIL HABITAT
To maximize the benefits of the urban forest there needs to be
a greater focus placed on the planting and protection of LST In
addition to planting LST the required soil volume & quality for
LST must be provided and protected during the trees Iifecycle.
MATURING TREED NEIGHBHOURHOODS
In several parts of the City (e.g. Westmount & Auditorium NA)
mature street trees are reaching the end of their life cycle. The
impact when these trees are lost will be significant. Using the
model developed for the Westmount pilot project, areas of the
City that are experiencing this problem should be priority areas
for future street tree management plans.
TREE CONSERVATION & PROTECTION
Protecting trees on City streets and in parks is a key element of
a sustainable urban forest. Building on the success of the tree
protection program developed for the City's road reconstruc-
tion projects staff plan to expand the program to protect all City
trees(e.g. parks, streets, other city lands) across the City.
STRUCTURAL & LIFECYCLE PRUNING
Structural pruning is one of the most cost effective actions that
can be taken to reduce long -term maintenance costs while
increasing the benefits of trees. A series of Iifecycle pruning
workshops are currently being developed for field staff. Staff
also propose to introduce a new structural pruning program.
TREE PLANTING IN NEW SUBDIVISIONS
Poor quality soils and a lack of space makes the planting of
trees in subdivisions challenging. Work is underway to develop
new tree planting standards for subdivisions. Options being
considered include reducing the number of trees planted and
placing a focus on soil quality and volume.

Kitchener's Natural Areas
Nature in the city
Valued for their natural heritage and by the community, natural areas are one of the six strategic
themes in the Parks Strategic Plan. Natural areas are the most dominant piece of the City's park sys-
tem accounting for more than 60% (975 hec) of the park land base. Natural areas provide significant
benefits to the community. The primary goals are to conserve the City's natural heritage, while provid-
ing places where people can experience nature in the city.
Kitchener's Natural Areas Program
With the hiring of a full time Natural Area Coordinator there has been significant growth in Kitchener's
Natural Areas Program. Community interest in the programing continues to grow. Education and
stewardship are key elements of a sustainable urban forest program. As this program grows the
community becomes more aware of the natural environment and what they can do to help conserve
these areas for future generations.
Pilot Natural Area Management Plan
Volunteer Meadow Restoration - HNA
Friends of Laurentian Wetland
With funding through LEAF, Operations is developing a pilot natural area management plan for the
Laurentian Wetland. The project evolved from a teacher at WT Townsend School who had an inter-
est and concern about the local wetland. Kitchener's Natural Areas Program became involved with
an event hosted by the school and local neighbourhood. Since that time the interest has expanded to
include the Williamsburg Community Centre, John Sweeney School, Kitchener Waterloo Field
Naturalists and the community at large.
In developing a natural area management plan a number of issues must be addressed including: the
dual purpose of the wetland in terms of natural heritage conservation and storm water management,
conservation (e.g. turtles) and management of wildlife (e.g. Canada Geese), appropriate public
access, invasive species, habitat expansion and encroachments. Once completed this pilot project
will provide the framework for other plans. Other community groups have already expressed an inter-
est in seeing a project like this in their neighbhourhood(e.g. Residents of Lakeside Park).
Huron Natural Area(HNA)
Kitchener's premier natural area
First envisioned in the early 1980's when most of the land
was zoned for development, today HNA is Kitchener's larg-
est natural area. It is a partnership with the Waterloo Re-
gional District School Board (WRDSB) and Waterloo Catho-
lic District School Board ( WCDSB). All three partners have
made investments into HNA through land purchases.
The original vision for HNA was to create a place where
people could learn about urban nature and practice stew-
ardship. The vision also called for the building of an envi-
ronmental education centre for the community.
Today the City is responsible for the management of HNA.
In recent years there have been investments into HNA by
the City, Province and business (TD Friends of the Environ-
ment). This money has been used to construct a new front
entrance, washrooms, event space and trails. The WRDSB
has a school portable on site that is used for environmen-
tal education. Kitchener's Natural Areas Program holds
its yearly Earth Day Celebration and uses the park as its
primary place for educational and stewardship activities.
The recent discovery of the Neutral Nation village, which
includes at least ten long houses, is one of the most sig-
nificant archeological sites in the Region. A boardwalk and
educational signs allow the community to visit and learn
about this special place.
To complete the vision of HNA more investments and work
are required.

NATURAL AREA MANAGEMENT PLANS
Operations is responsible for the long term management of
Kitchener's natural areas. Management plans for all natural areas
will be developed over time using an asset & ecosystem manage-
ment framework.
CONSERVATION \ ECOLOGICAL RESTORATION
Conserving the natural heritage (e.g. wetlands, rare species) for
today and future generations will be a key focus of the manage-
ment plans. Where required and appropriate ecological restora-
tion will be used to conserve Kitchener's natural heritage.
PUBLIC USE & TRAILS
Trails and public use are important components of the City's
natural areas. Unless managed and controlled impacts can be
significant. Natural area management plans will balance the
needs for conservation with public use.
WILDLIFE MANAGEMENT
With the increased number of natural areas in the City there are
increased opportunities to view and learn about urban wildlife.
Wildlife can have positive or negative impacts on an area(e.g
changes in vegetation structure). To achieve the desired goals in
some cases the management of wildlife will be required.
INVASIVE SPECIES
Invasive species are a threat to the health of natural areas. To
manage this issue three them es(education, stewardship, control)
will be included in the plans. The type of action taken will vary by
species (e.g. use of volunteers, chemical control).
NATURAL AREA EDUCATION & STEWARDSHIP
In 2011 Kitchener's Natural Areas Program(KNAP) offered 28
educational and stewardship events that were attended by 1,314
people. Connecting people with nature has important social ben-
efits and helps conserve Kitchener's natural heritage.
ENCROACHMENTS
Encroachments into Kitchener's natural areas are a serious prob-
lem that affects their long -term health. A new strategy of educa-
tion and enforcement is required to address this issue.
Council Feedback
Points of discussion
In the spring of 2011 staff presented information on a sustainable urban forest for Kitchener to the
Environmental Committee. Recognizing the work being done, and its strategic connections it was felt
this issue should be brought to Council. In presenting this information at a Strategic Council Session
staff are looking for feedback on the urban forestry strategies presented, six key themes are identified
below:
COMMUNITY SUPPORT AND ENGAGEMENT
Input and participation from the community shows the urban forest is a high priority. Recognizing
the economic, environmental and social benefits of the urban forest direct linkages can be made
to the City of Kitchener's Plan for a Healthy Community and Strategic Policies (e.g. Strategic
Plan for the Environment, Parks Strategic Plan, Corporate Asset Management Project).
URBAN FOREST AN ESSENTIAL ASSET
The scientific research provides a strong argument to recognize the urban forest as an essential
service. Once recognized the next step is to actively manage the resource in an asset \ ecosys-
tem framework that maximizes community benefits for the least cost.
OPERATIONS SERVICE PRIORITIES
Recognizing the benefits of the urban forest and community support staff have identified the de-
velopment of a sustainable urban forest plan as part of Operations Infrastructure Services Draft
Business Plan - Service Priorities (2012- 2014).
BEST MANAGEMENT PRACTICES
The development of Best Management Practices(BMP) based on scientific research is a key part
of a sustainable urban forest. Implementing BMP's will require a change in work practices for
Operations, other City Departments and the Community. It will also require focused investments
(e.g. structural pruning) to maximize community benefits while reducing long term costs.
EMERALD ASH BORER
The financial impact of Emerald Ash Borer (EAB) will be significant. Current information suggests
the full impact will not be felt for a few years. As tree mortality increases Operations will not be
able to address the increased workload while maintaining other service levels. To address this
issue new Capital (e.g. education, monitoring, removals, replanting) is identified in the 2012 Ten
Year Capital Budget Process. At this time the full cost of EAB is still not fully quantified.
URBAN FOREST BUDGETS
Based on outdated beliefs and the inability to quantify the benefits in the past, Kitchener's bud-
gets for urban forestry have been underfunded when compared to other strategic assets. As a
step towards developing a sustainable urban forest, staff have identified priority areas(e.g. tree
protection, management plans & implementation, structural pruning, large tree conservation,
natural area restoration) to be considered in the 2012 Ten Year Capital Budget Process.
