| FORESTRY DEPARTMENT
The Forestry Department is responsible for the design, planning,
planting and management of publicly owned trees along the streets,
parks, landscape green spaces, natural areas, woodlands, within
the City of Vaughan.
This includes tree removal of dead or hazardous trees, removal
of hazardous limbs and trimming for traffic and pedestrian hazards
and clearances.
The primary goal of is to effectively preserve and manage the Urban
Forest, thus providing a better quality of life for our residents.
We also serve as a resource for other departments and public in
streetscape design, tree preservation and community planting projects.
Tree Management
The City of Vaughan’s Forestry Department is responsible for the
care and maintenance of street, park and woodland trees.
They annually maintain and prune 20,000 trees as part of the block
pruning cycle.
Trees are pruned for public safety, to maintain adequate clearances
over public roads, sidewalks, traffic signage and streetlights.
Pruning is also done to remove hazardous branches that could cause
injury or property damage and to promote good branch structure.
All brush is chipped and re-cycled into mulch for parks and street
trees.
Inspection & Assessment
Hazard Trees
The City of Vaughan’s Forestry Department manages all street, parks
and woodland trees.
Whenever trees or parts of trees pose a threat to people or property,
they are classified as hazardous trees and receive
priority one attention.
Our Forestry Inspectors are responsible for inspection and assessment
of thousands of trees annually thus ensuring a safe urban forest.
All Forestry work is inspected and prioritized in the following
manner:
Priority 1. Immediate danger to life or property. Example: dead
tree in poor condition, serious traffic hazard, broken limbs, fallen
trees.
Priority 2. Hindrance or nuisance to traffic or right-of-way clearance,
but not an immediate danger to public safety. Example: dead trees
that are still solid, trimming of solid deadwood, low limbs, and
minor traffic hazards.
Priority 3. Routine maintenance that does not present a hazard.
Example: minor trimming and low branching, aesthetic pruning, trunk
removal.
Our Inspectors look for the following when checking hazardous tree:
- large dead branches in the tree
- hanging branches
- rotten wood or cavities in the trunk and main branches.
- cracks or splits in the wood that could lead to failure.
- root problems that could affect the structural stability of
the tree.
If you have concerns regarding your street tree, please contact
the Forestry Department at 905-832-8577.
Tree Pruning
Why Prune Trees?
Pruning is the most common and important tree maintenance practice.
Well pruned trees look better, are healthier, safer and lives longer.
Improperly cared for trees, shorten the life of the tree.
Trees are pruned for:
- public safety
- to provide height clearance for pedestrian and vehicular traffic
- remove dead branches
- eliminate hazards
- remove crowded & rubbing limbs
- increase air and light penetration into the trees crown
- remove multiple leaders and promote a strong central leader
- develop proper structure.
Pruning Cycle
The Forestry Department cares for street and park trees throughout
the city. The city uses a block pruning cycle to prune trees.
The block pruning cycle allows staff to maintain safe clearances
above roads and sidewalks and develop proper branch structure and
strong central leaders. The block pruning cycle is an efficient
system of tree maintenance.
Construction Management
The Forestry Department works with other agencies to prevent construction
damage to city trees during all construction activities, including
the installation and repair of utility services.
The Forestry Supervisor reviews both public and private construction
plans, advises alternatives to reduce tree damage, inspects works
in progress and cost recovery for damages to city assets.
FREQUENTLY ASKED QUESTIONS
1. I would like my boulevard tree pruned. Who do I contact?
The Forestry Department provides care for all the trees on city
owned property. This includes tree removal of dead and hazardous
trees, removal of hazardous limbs and the trimming for traffic and
pedestrian hazards and clearances.
Please contact Vaughan Forestry at 905-832-8577.
2. I would like a tree planted in front of my house? Who
do I contact?
The City of Vaughan’s Forestry Department is responsible for street
tree planting in established neighbourhoods, industrial areas, parks,
road reconstruction and beautification projects. The department
annually plants between 1000-1500 trees.
Trees are planted, to provide beauty, help to improve the air quality
and add economic value to your neighbourhood.
The City contracts out the supply and installation of trees. The
Forestry Supervisor visits the tree nursery and selects and marks
all trees.
Prior to planting, the Forestry Supervisor identifies and marks
all tree locations.
The following is a list of criteria used in selecting location
and tree species:
- underground and above ground utilities
- wet or dry site
- shady or sunny
- mature height and shape
- tree projected longevity
- flowers or fruit
- susceptibility to diseases or insects
- sensitivity to salt
Should you like a tree planted in the public boulevard, please
contact the Forestry Department at 905-832-8577.
3. Why should I not top trees?
Topping is the senseless practice of removing a majority of a trees
branches and is not an acceptable arboricultural practice.
Important facts to remember about topping:
- Topping will not make trees safe, it creates a hazardous tree.
- Topping makes a tree more susceptible to storm damage.
- Topping makes a tree more prone to insect and disease problems.
- Topping is a waste of money.
CORRECT PRUNING IS THE BEST THING THAT YOU
CAN DO FOR YOU TREE!
It is illegal to top public trees. If you would like your
City tree pruned, please contact the Forestry Department at 905-832-8577
4. Why does PowerStream trim trees?
Trees that grow into electrical lines are the leading cause of
power outages
Trees add significant beauty and value to our communities but they
can also pose hazards to property.
This is why you see PowerStream staff trimming trees on your streets
and in your neighbourhoods.
When staff evaluate trees for trimming, the utility’s primary objective,
is to prevent outages, as well as to maintain the aesthetic integrity
of the trees.
Sometimes it is necessary for staff to trim trees severely to maintain
adequate clearances around its wires. The PowerStream staff sometimes
removes large branches to train future growth of the tree away from
the wires.
If this cannot be achieved, the City’s Forestry Representative
will assess the tree and may opt to remove the tree rather than
create an eyesore.
The tree will be replaced during the regular planting season with
recommended trees for under power lines.
PowerStream staff follows established city and industry pruning
standards.
Should you any questions or require further information, please
contact the Forestry Department at 905-832-8577. For the hydro pruning
schedule, please contact PowerStream at 905-417-6900
5. The tree roots are damaging my sewer pipe. Who is responsible?
In the City of Vaughan, each property owner is responsible for
the entire sewer pipe up, to the property line.
Tree roots are often blamed for blocking sewer pipes; however,
tree roots only penetrate sewer pipes that were previously damaged
by other factors such as poor construction, aging and soil settlement.
When the small exploratory roots come into contact with cracked
or leaking pipe, they are stimulated to grow vigorously often into
the damaged pipe.
The combination of roots and solid wastes will usually develop
into a partial or complete blockage of the sewer line.
- The following is a list of treatments available to homeowners
to correct blockage problems in the sewer line.
- Plumbing contractors have equipment for removing blockages from
the sewer lines. This method provides short-term solution.
- Chemical root inhibitors are available to kill roots.
- Copper sulphate can be used to kill roots within sewer lines.
- Sewer pipe liners are inserted into the sewer and positioned
into the damaged area of the pipe.
- Replacement of the sewer pipe in severe cases is the only effective
solution.
TREE ROOTS AND SEWERS
ROOT FACTS:
Most roots grow horizontally and upward through soil.
Most roots are in the top foot of soil, few are deeper then 1metre
(3ft.).
Many roots extend radially far beyond the tips of the branches.
Roots grow best in the upper layers of the soil because the available
water and nutrients are concentrated in these layers.
Roots will not grow where moisture and oxygen are available.
Tree surface area of the root system is larger than that
of the leaves and branches.
6. Does the City have a memorial tree program?
The City of Vaughan has a Tree Dedication program that provides
an opportunity for trees to be planted in neighbourhood parks to
commemorate a birthday, anniversary, or other special occasions.
Please contact the Forestry Department at 905-832-8577 to obtain a Tree Dedication brochure.
7. Does the City supply mulch?
Wood chip mulch can be obtained from the Forestry Department by
calling 905-832-8577.
Residents can obtain mulch in the spring and fall, for a minimal
fee. Residents should bring sturdy bags, blue boxes, garbage cans
or other containers.
In special situations, the City can deliver large loads of mulch
directly to your property, a minimum one (1) yard minimum.
Remember to cover your load of using a pickup truck or trailer.
City staff is available to assist in bagging and loading mulch.
8. What to do with tree surface roots?
The surface roots of a tree can make cutting or growing grass extremely
difficult and frustrating
The roots of the tree, provides mechanical support as well as nutrients
and water uptake for the trees. Many species will naturally develop
surface roots; others develop surface roots because of soil compaction
and improper watering.
Roots naturally grow in the top 10-20 cm of the soil. They also
extend beyond the crown edge.
The City if Vaughan’s Forestry Department does not remove surface
roots on city street trees.
Cutting roots is not recommended because cut roots, creates an
entry way for harmful insects and diseases.
Burying roots disrupts natural root functions and is a temporary
solution. The trees roots will resurface.
Solutions:
Mulching
Apply a 10cm(4") layer of mulch over the surface root. This
will benefit the tree by creating a better growing environment,
keep weeds suppressed and keeps lawn mowers and string trimmers
away.
TIPS:
- KEEP SURFACE ROOTS IN PLACE
- DO NOT CUT ROOTS
- DO NOT BURY ROOTS
- REMEMBER THE ROOTS ARE IMPORTANT FOR THE STABILITY AND HEALTH
OF THE TREES
9. Private Tree Failure on Public Property. Who is responsible?
If a private tree falls into a street, only that portion of the
tree that is on public property will be removed. The remainder of
the tree is the responsibility of the property owner.
10. Who do I contact for trees on York Region roads?
York Region Forestry is responsible for the maintenance of trees
on all regional roads, example: Hwy #7 & 27, Centre Street,
Yonge Street, Dufferin Street, Keele Street, Rutherford Road, Major
Mackenzie Drive.
For all enquiries, please contact York Region Forestry at 905-764-6346.
11. I live in a new subdivision, my street tree is dead.
Who do I contact to have it replaced?
The planting of all street and buffer trees in new subdivision
is the responsibility of the Developer/Builder. Please contact your
builder/developer directly for replacement of dead street trees,
new tree planting and refunds.
The City of Vaughan does plant trees in new subdivisions. Once
the subdivision is assumed by the City, all tree maintenance and
replacement plantings is the City’s responsibility.
12. Who is responsible for trees encroaching street lights?
The City of Vaughan Forestry Department is responsible for clearing
all vegetation from streetlights.
When a City tree encroaches a streetlight, the Forestry Inspector
will assess the tree and determine the best method of pruning that
clears the light but does not affect the health of the tree.
In some cases, the tree may be removed to achieve adequate light
levels.
All efforts are made to protect the trees.
Should you have a streetlight/tree conflict, please contact the
Forestry Department at 905-832-8577.
EDUCATIONAL
TREE PLANTING
How to Plant Your New Tree
1. Select the right tree for the right place. Proper tree planting
begins with planning.
2. Prepare a planting area as deep as the rootball and 2-5 times
wider than the rootball diameter by loosening the soil. Dig a hole
in the middle of the area and set the rootball even with the ground
level.
3. The bottom of the rootball should rest on solid undisturbed
soil. This prevents settling.
4. Make sure the sides of the hole are rough and uneven.
5. Place the tree in the hole. If the tree is in a container, remove
the container. Place the rootball in the centre of the hole and
adjust the tree so it s straight and at the proper level.
Note: Do not bury the trunk. It should be planted at the same level
as in the container.
6. Now is the time to make any adjustment.
7. Backfill with the original soil. Tamp gently with your foot
to firm up the soil. Apply clean water to settle the soil and remove
air pockets. Repeat this process until the hole is filled and the
soil is firm and can support the tree upright.
DO NOT MIX FERTILIZER, COMPOST OR OTHER
MATERIALS WITH THE ORIGINAL SOIL.
8. Construct a small dam or berm three feet in diameter around
the tree. The dam will hold water rather running off.
9. Cover the entire loosened area of soil with 10cm (4") of
mulch. The mulch will reduce competition from weeds and grasses,
moderate soil temperature and provide nutrients as the mulch decomposes.
Tree Care of Your Newly Planted Tree
Monitor your tree for insect and disease problems, dead or broken
limbs.
Regular watering is important. New trees need about 5-10gallons
of water per week for about two years if the rainfall is low. Do
not drown trees by over watering.
Do not apply fertilizer at time of planting. Sprinkle a balance
fertilizer over the planting area the following spring. Too much
fertilizer will injure the tree.
Always follow the manufacturers directions or contact a
local Arborist for proper diagnosis.
Keep a good mulch layer within the planting area. Keep the mulch
away from the base of the trunk.
Prune only dead, damaged, diseased or crossed or rubbing branches
Never prune tree near power lines. Contact a local Arborist for
this service.
MULCHING
Mulch serves a dual purpose of retaining moisture in the soil and
providing extra nutrients for the plants as the mulch decomposes.
Mulching helps young plants get established.
Mulching helps keep roots cool and moist in the summer and insulated
in the winter.
Mulch suppresses weeds and competing grasses.
Mulching provides an important barrier against lawnmowers
and string trimmers.
The larger the area mulched, the better for the tree.
Apply a 10cm (4") layer of organic mulch such as back mulch
or wood chips, around the trees and shrubs.
Do not pile mulch around the base of the tree. Over mulching trees
can lead to rot around the base of the trunk.
Keep mulch 5cm (2") away from the trunk.
Lawn clippings or leaves are poor mulch materials because they
compress and mat together restricting air and water movement.
By following these mulching steps, you will be able to
provide your tree the benefits of mulching but avoid the hazards
of over mulching.
BENEFITS OF THE URBAN FOREST
The urban forests are the lungs, air conditioners and natural filters
of our city.
It is important to recognize the trees within the city boundaries
that play a key role in our social, economic and environmental surroundings.
The urban forest adds natural beauty to our urban surroundings
and merges the habitat where people, plants, birds and animals live.
One acre of the forest absorbs 10 tones of carbon dioxide per year
which translates into less carbon dioxide build-up in the atmosphere.
People living in constant views of trees, parks, woodlands enjoy
better health.
The quality of the Urban Forest is a major factor in establishing
the quality of our community life.
BENEFITS OF TREES
- trees add beauty and natural character to our neighbourhoods
and communities.
- trees produce oxygen
- trees improve our air by capturing pollution in leaves and reduce
carbon dioxide
- trees trap and hold harmful pollutants
- trees provide shade and cooling in the summer months and windbreaks
in the winter months thus energy savings. Well placed landscaping
can reduce air conditioning costs up to 20 percent.
- trees provide privacy and help reduce noise pollution.
- trees have a psychological impact, thus reducing stress.
- trees provide economic value to our neighbourhoods and communities.
- trees provide food and shelter for wildlife connecting our rural
forests.
- trees improve water quality of our streams and rivers by capturing
rainfall and reducing erosion and runoff.
- trees make our streets feel safer
- trees increase property value and saleability
WINTER PREPARTION OF EVERGREENS
Preparing Your Conifer Tree
Winter is a difficult time for trees. Food reserves must be conserved
for the needs of spring. Strong winds during winter draw moisture
from the needles as a result some needles turn brown and die.
It is important to water evergreens well before winter because
evergreens lose moisture from their needles in the winter.
Deciduous trees lose their leaves in the winter and are less susceptible
to drying out.
All trees should be well watered in the fall as a routine practice.
In September, evergreens should be soaked once. This will assist
in the hardening-off of trees in preparation for winter.
Give the trees a soaking in late October, before the ground freezes.
Spread a thin layer of mulch to blanket the soil.
To protect low growing conifers, construct a burlap windbreak.
This will trap snow, which provides excellent protection.
HINTS FOR HEALTHY TREES
Do water your trees every week during the summer.
The best method of watering is to use a soaker hose.
Do take care not to hit tree trunks with lawnmowers
and string trimmers. Tree wounds provide entry points for harmful
pests and diseases.
Do handle lawn fertilizers with care.
Don’t drive nails into trees or attach wire to
trees.
Don’t allow vehicles or machines to be parked
on the soil around tree. Soil compaction decreases the oxygen and
water available to roots.
Don’t contaminate tree soil with de-icing salt.
Salt can harm trees.
How to Care For Your Tree
The trees planted on your street were carefully chosen and planted
to provide shade, windbreaks, and privacy, attract wildlife and
to beautify your neighbourhood. In an effort to keep the trees healthy,
the City’s Forestry experts ask you to help maintain your new tree
by following these tips:
- keep lawn mowers and string trimmers away from the stem of the
tree to avoid damage to the bark. Repeated bark damage can result
in the eventual death of the tree.
- please leave the wood chips in place as they reduce water loss
and add nutrients during decomposition.
- please do not pile soil or grass clippings over the mulch.
- do not remove the wood stakes. The stakes stabilize the tree.
The Citys tree planting contractor will remove the stakes at the
end of the warranty period.
- if you maintain a healthy lawn and boulevard, the tree will
receive sufficient amounts of water.
- during dry periods, water your tree twice a week. Please do
not over-water.
- we suggest fertilizing after the two year warranty period expires.
Please do not use a granular fertilizer/ weed control
mix. We recommend applications of 1 cup of 10-10-10 (slow
release) fertilizer in April and October for root and top growth.
Please report any problems (ie.Vandalism, insect, disease) to the
Forestry Department at 905-832-8577.
