1.0 OVERVIEW
This Tree Conservation Report has been prepared for The Wood Source (613‐822‐6800) in support of Site
Plan Application to permit the development of the 6178 Mitch Owens Road, Manotick, Ontario.
The approximately 4.5 hectares property at 6178 Mitch Owens Road, east of Manotick Station Road, consists
of one parcel of land currently developed with an existing two storey store and office building, a mill, and a
storage shed complete with asphalt parking areas and outside lumber storage areas. The site is described
legally as Part of the North ¾ of Lot 1, Concession 3, Township of Osgoode, now in the City of Ottawa. The
site is designated Rural Natural Features Area in the City of Ottawa Official Plan and designated Rural
Commercial Zone (RC4i[181r]) in the 2008 City of Ottawa Comprehensive Zoning By‐law.
This Tree Conservation Report will summarize the condition of the current vegetation and define which trees
will be impacted by the development of this project. The construction of this project is planned to happen in
2013‐2014, construction starting August 2013 and ending in December 2014.

2.0 INTRODUCTION
This Tree Conservation Report outlines the condition of all existing vegetation on site, the impact of
development on the vegetation and the mitigation measures recommended to preserve and minimize impact
on the conserved vegetation. The protection of a variety of trees on site will serve to improve the overall site
plan and promote a diverse vegetative landscape.
Vegetation field surveys were conducted on May 23 and September 7, 2012, by Heather Lunn, and Isabelle
Lalonde from McIntosh Perry Consulting Engineers to review the species and basic conditions of the trees and
large shrubs located at 6178 Mitch Owens Road in Manotick, east of Manotick Station Road.
The objectives of this Tree Conservation Report are:
To describe the existing woody vegetation (trees and large shrubs) growing on site including species
composition, size, vigour and health condition;
To assess the woody vegetation functions including environmental value, ecological function,
aesthetics, sensitivity to grade changes, drainage, sun and wind exposure, etc.;
To produce a document describing the forested area including stands of trees and individual trees
which may be candidates for consideration of conservation measures; and
To provide a professional opinion on the retention of woody vegetation.
2.1. Definitions
Some of the basic terms used within this document and on the plans have been defined below. Potential
protection techniques and remediation measures have been noted.
Critical Root Zone (CRZ): Zone under a tree where there should be no disturbance before, during
and after construction. The CRZ is established as being 10 centimetres
from the trunk of a tree for every centimetre of trunk diameter.
Diameter at Breast Height (DBH): Diameter of a tree trunk measured at 1.4 metre above ground,
standardized by the Council of Tree and Landscape Appraisers and the
International Society of Arboriculture.
Dieback: Condition in which the ends of the branches are dying.
Drip Line: Perimeter of the area under a tree delineated by the crown.
Leader: The primary terminal shoot or trunk of a tree.
Scaffold Branches: The permanent or structural branches of a tree.
6178 Mitch Owens Road Tree Conservation Report

Significant Tree: Tree / shrub deemed valuable because it is unusually beautiful or
distinctive, comparatively old, distinctive in size or structure for its
species, rare or unusual in the subject area, provides a habitat for rare
or unusual wildlife species in the subject area, or has an historical,
cultural, or landmark significance.
Significant Woodland: Woodland that contain mature stands of trees 80 years or older, have
interior forest habitat more than 100 metres from forest edge, and are
adjacent to a surface water feature.
Specimen Tree: Individual tree located in the middle of a field or open space. A
specimen tree is not automatically a significant tree.
Stress: Any factor that negatively affects the health of a tree.
Structural Defect: Flaws, decay, or other faults in the trunk, branches, or root collar of a
tree, which may lead to failure.
Topping (Topped): Cutting back a tree to buds, stubs, or laterals not large enough to
become a new leader on the tree.
Tree Sapling: Young tree measuring more than 1.50 metres high.
Tree Seedling: Young tree measuring less than 0.60 metre high.
Tree Shoots: Tree shoots are sprouts that emerge from dormant buds along the trunk
or branch of a tree. In an urban environment shoots are often
associated with stress to the tree. Trees with severe dieback due to
winter injury, drought and salt spray often produce many shoots as a
means of compensating for the loss of leaf surface due to stress or
injury.
Tree Suckers: Tree suckers are sprouts that form from the roots of existing trees and
tend to form new trees or shrubs. In an urban environment suckers can
be associated with stress to the tree and are prevalent after a
disturbance such as when mature trees are cut down. Some tree
species have the tendency to sucker.
Tree Whips: Young tree measuring between 0.60 and 1.50 metres high.
Vigour: Overall health; capacity to grow and resist stress.

3.0 CURRENT VEGETATION
The inventory and analysis was a visual inspection of the tree species and their condition. The species were
determined based on leaf, bark and buds identification. The vigour was assessed based on visible defects
only.
3.1. Methodology and Observations
The property consists of a commercial mill with a store/office building, a mill, storage sheds, parking areas
and outside lumber storage spaces. In general the site is flat and is vegetated with large wooded area where
there is no building or other uses. The lot east and south of the property is the Emerald Links Golf & Country
Club and the lot located west of the subject land is the Osgoode Link Pathway, a 21 kilometre pathway
running on an abandoned rail corridor from Leitrim Road to Buckles Street.
Two methods of field inventory were used during the vegetation assessments:
A general inventory was conducted on the entire property and adjacent properties to determine the
species compositions of the wooded areas. The wooded areas on site are a mix of mature trees with
a large number of small trees with a Diameter at Breast Height (DBH) of 15 centimetres or less.
Because of the number of trees and the size of the subject land the complete assessment of every
tree was not possible. For the purpose of this report and based on our field observations the wooded
areas were divided into vegetated zones. Each vegetated zone is distinct from another zone for its
species composition.
A detailed inventory was conducted in the north‐east portion of the property, where the
development of the site is proposed. In this area a complete assessment of every tree with a DBH of
10 centimetres in diameter or bigger was completed.
The list of all trees located in the north‐east portion of the property can be found in Appendix A – Individual
Tree Survey and the list of all wooded areas are described in Appendix B – Wooded Areas. Both tree surveys
are to be read in conjunction with the Overall Current Vegetation Plan (TC‐0) and Current Vegetation Plan
(TC‐1) accompanying this report. The approximate location of individual trees on the property was
established on site and is for reference purposes only. The location of these trees and their size should be
confirmed by a tree inspector.
In general the trees inventoried on this property appeared to be in healthy conditions, are a mix of saplings
and mature trees and show no apparent signs of disease. A total of 68 trees were assessed for their DBH.
The trees inventoried on this property are primarily a mix of deciduous and coniferous species including apple
trees (Malus spp.), white ash (Fraxinus americana), Manitoba maple (Acer negundo), American elm (Ulmus
americana), ironwood (Ostrya virginiana), white spruce (Picea glauca) and eastern white cedar (Thuja
occidentalis). The approximate DBH noted on the Overall Current Vegetation Plan, the Current Vegetation
6178 Mitch Owens Road Tree Conservation Report

Plan and in this report were measured on site during the tree inventory site visit. With the exception of the
trees located on the property line, the trees growing on this site have an average DBH of 20 centimetres to 30
centimetres.
3.2 Environmental Value of the Trees and Their Ecological Function
Overall the majority of the trees composing the wooded areas on this property are not of significance. As
indicated in Appendix A and Appendix B, trees found in larger number on the subject land are Manitoba
maple and white ash. The Manitoba maple is a fast growing tree that establishes itself independently and
flourishes on many inhospitable sites. This tree is considered a weed species. The white ash is a tree
commonly found in wooded areas throughout Ottawa and the rest of Ontario. A total of 32 white ash trees
(Fraxinus americana) were inventoried for their DBH in the north‐east portion of the property and a number
of saplings were also observed during our site inventories. Since 2008 ash trees located in the Ottawa region
are affected by the Emerald Ash Borer (EAB). The EAB is a non‐native, wood boring beetle attacking and
destroying all species of ash trees. Because of the impacts on ash trees and to limit the spread of EAB the
Canadian Food Inspection Agency has issued a ministerial order to prohibit movement of firewood and ash
tree products such as nursery stock, logs, branches and wood chips from areas of Ottawa to any other
surrounding regions. During our field investigation we did not observe any signs of EAB on any white ash
however special precaution will be required when removing and working around ash trees. Special mitigation
measures will be described in the following section of the report.
None of the trees on the site are considered to be species at risk but there is potential to preserve parts of
the wooded areas for aesthetic reasons and to provide a more mature character in keeping with the existing
character of the adjacent neighbourhood. All efforts should be made to protect and preserve trees located
on site during construction if they fit in with the proposed development. Factors influencing preservation will
be the amount of grading required at the base of the trees and the proximity of access roads, concrete curbs,
servicing and/or built structures. Care will have to be taken to reduce the impact of construction on any trees
that are to be preserved. Most of the construction impacts for this project will be in the form of new
buildings, new hard surfaces and the grade changes impacts on the roots of the trees.

4.0 PROPOSED DEVELOPMENT AND CONSERVED VEGETATION
The project for 6178 Mitch Owens Road involves the construction of a new mill warehouse and a new
showroom/warehouse with associated asphalt drive aisles, parking, gravel storage yard expansion and
landscaping areas. The proposed development shown on the Proposed Development and Conserved
Vegetation Plan (TC‐2) indicates the location of the proposed additions and affiliated infrastructures.
4.1 Conserved Vegetation
The proposed development of the subject land is contained in the northeast portion of the site. All wooded
areas located outside this zone is to be preserved at all time during construction. The limit of work and the
list of all trees to be conserved is indicated in Appendix A and B and on the Proposed Development and
Conserved Vegetation Plan (TC‐2) accompanying this report. Special mitigation measures will be required
when working around these trees. All conserved vegetation on site should be preserved at all times using the
mitigation measures indicated below.
4.2 Impacted Vegetation
Existing trees located in the northeast area of the subject land will be impacted by the development of this
site. A total of 64 trees will be impacted by the development of the project. The complete list of all trees to
be removed due to construction can be found in Appendix A – Individual Tree Survey. The Tree Survey is to
be read in conjunction with the Proposed Development and Conserved Vegetation Plan (TC‐2) accompanying
this report. Special precaution to adjacent vegetation to remain should be taken when removing any trees.
Impact on vegetation can be due to construction of new buildings and roads, grade change, changes to
drainage patterns, and effects of impervious surfaces.
4.3 Tree Protection Measures
Trees can be damaged in a number of ways during construction. The most common injury is to the crown or
trunk. These injuries are visible and permanent and in some cases can be fatal to the tree. The roots are
susceptible to physical injury through the cutting of the roots, soil compaction and/or smothering of the
roots. The roots of a tree are located in the top 150 to 250 millimetres of soil and can very easily be
inadvertently damaged. A vehicle parking under the root zone of a tree can compact the soil reducing the
roots ability to absorb nutrients and uptake water. A change in grade of more than 150 millimetres over the
roots will reduce its health and vigour. At any time no root system, trunk or branches of any tree should be
damaged.
Protection of the Root Systems 4.3.1
Within the critical root zone (CRZ) of trees to be retained / conserved and located within construction limits
there must be:
6178 Mitch Owens Road Tree Conservation Report
7
No disturbance or alteration of the existing grade of any kind without approval;
No addition of fill, excavating, or scraping to change the grade;
No signs, notices or posters to be attached to any trees;
No storage of construction materials or equipment;
No storage of surplus soil, construction waste, or debris over the root systems of the protected trees;
No disposal (dumping or flushing) of contaminants or liquids; and,
No movement of vehicles (personal or business), equipment or pedestrians.
At any time during construction, root systems should not be damaged. In the event that a tree has roots that
will be impacted by construction work, the Contractor shall only tunnel or bore when digging within the CRZ.
The roots should only be cut by hand with a sharp spade or knife at the limit of disturbance prior to any
construction activities. This will ensure that the roots are not disturbed more than necessary. Any root
pruning requires the service of a Certified Arborist or Qualified Tree Worker under the supervision of a
Certified Arborist. Any roots that are exposed must be covered with native topsoil immediately, to ensure
that the roots do not dry out or have any further damage occur to them. All remedial works must be
conducted by a certified care professional to ensure proper care is administered in order to enable the
continued health of the trees.
Fencing 4.3.2
Before construction, fencing should be erected at the critical root zone (CRZ) of trees located in the
construction area to ensure that this protection is achieved. Tree protection barriers shall be installed
according to information on the Proposed Development and Conserved Vegetation Plan (TC‐2). Fencing shall
be maintained erect and in good repair at all times during construction operations, and shall be removed
upon completion when agreed by City staff. Temporary removal of fencing will not be considered without
approval.
Additional Protection Measures 4.3.3
When working near vegetation the Contractor shall ensure that exhaust fumes from all equipment are NOT
directed towards any tree’s canopy.
The Contractor shall take every precaution necessary to prevent damage to the trees to be retained /
conserved.
Where limbs or portions of trees are removed to accommodate construction work, they will be removed
carefully in accordance with accepted arboricultural practices.
Where necessary, the trees will be given an overall pruning to restore the appearance of the trees. Not more
than one‐third of the total branching shall be removed at a single operation.
6178 Mitch Owens Road Tree Conservation Report
8
Trees that have died or have been damaged beyond repair by the Contractor shall be removed and replaced
by the Contractor at their own expense with trees of equal size and species or as directed by City staff.
Damages will include:
Any physical damage on tree bark;
Any broken branches;
Equipment and materials stored within the protected areas and beyond the limits of the contract;
and
Refueling of equipment within the protected areas.
Special Measures for the Removal of Ash Trees 4.3.4
During the field inventories, we did not see any signs of EAB on any ash trees growing on site; however this
does not confirm the insect is not present. Because of the potential of EAB on site and since the City of
Ottawa is located inside the EAB Regulated Areas by a Ministerial Order the Contractor will be required to
follow special measures when removing or pruning ash trees. Any non‐processed (not debarked) ash
products (logs, branches, etc.) can only be moved freely inside the jurisdiction of the City of Ottawa. In order
to limit the movement of ash products for long distances within the City of Ottawa limit, different options are
available for the Contractor when processing ash products:
Moving logs and firewood from large branches (more than four inches in diameter) as close to
Manotick as possible;
Bringing a portable sawmill on site to process the timber;
Chipping and disposing all small branches (less than three to four inches diameter) on site;
Moving all ash products to the Trail Road Waste Disposal Facility.
When cutting ash trees the Contractor shall separate ash products from other timber species on site to
ensure the products are easily identified for processing. The Owner and Contractor shall also ensure that any
ash products will not be move outside the EAB Regulated Areas / Ministerial Order Area.
4.4 Tree Planting Recommendations
Tree planting recommendations for 6178 Mitch Owens Road should implement the natural and rural
character of the existing area. Because the property located east and south of the subject land is a golf
course a landscaped buffer should be maintained and implemented along the eastern property line. In
general, proposed tree species should be a mix of deciduous and coniferous trees. Where possible the use of
native, non‐invasive tree species should be preferred. Examples of species adequate for this site are maple,
ironwood, spruce, and cedar.

5.0 CONCLUSION
There are several trees that are in good condition and should be protected during construction on the site.
Photos of each tree should be taken prior to construction, when the trees are in full leaf, as a record of its
condition. This will provide a record of the existing condition that can be used if the tree is damaged or is
showing signs of decline to determine if the condition is a result of construction activities.
