Environmental Impact Study 2
Executive Summary
Species at Risk Consulting and Ecological Services was retained by Mr. David
Henderson to complete a scoped Environmental Impact Study to address environmental
concerns with regards to the impact the proposal to sever part of lot 35 Concession 1,
geographic township of Gibson, Municipality of Georgian Bay, into a total of three lots,
could have on the natural heritage features of the property, specifically habitats of
Species at Risk (i.e., reptiles in this area) and significant wildlife habitat.
Fieldwork was conducted on the subject property in mid October, not the most
appropriate time to find and confirm species use of the habitats but within the window to
identify the significant habitats of the Species at Risk and rare vegetation communities of
the area.
Although no Species at Risk were seen during the fieldwork component, likely as a
result of the late season fieldwork, a number of potential Significant Habitats of the
identified Species at Risk were found. In addition to the Species at Risk Habitat the
property was generally assessed using an Ecological Land Classification system design
exclusively for the Eastern shore and islands of Georgian Bay.
In conclusion, Species at Risk Consulting and Ecological Services has identified
natural features worthy of protection and has made recommendations that if agree to and
the appropriate planning action taken will ensure the long-term protection of the
Significant Habitats of Threatened and Endangered Species, the Significant Wildlife
Habitat, and Type 1 Fish Habitat.

Environmental Impact Study 5
1 Introduction
1.1 Background
A Scoped Environmental Impact Study (EIS) for an application to sever an existing
6 ha property, part of lot 35 Concession 1, geographic township of Gibson, Municipality
of Georgian Bay, into a total of three lots, was undertaken at the request of Mr. David
Anderson as per the requirements of Township of Georgian Bay Official Plan and the
Provincial Policy Statement (2005).
1.2 Purpose and Scope of Study
To address the township’s concerns, the study determined the potential impacts the
proposed severance of the property and subsequent development plans may have on the
natural heritage and how any unacceptable impacts can be eliminated or minimized. More
specifically, Species at Risk Consulting and Ecological Services was retained to:
determine the subject property's significant habitat of threatened and
endangered species and ensure its protection,
determine the subject property’s significant wildlife habitat and ensure its
protection, and
ensure that the proposed application acts in accordance with policies set out
in the Provincial Policy Statement (2005).
1.3 Location and Description of Property
The property is located on the mainland north of Beausoleil Island, east of Webber
Island, west of McCrae Lake in Southeastern Georgian Bay. The subject property consists
of White Pine (Pinus strobus) - Red Oak (Quercus rubra) mixed forest with an
understory typical of this common Eastern Georgian Bay community, dominated by
Canadian Mayflower (Maianthemum canadense), Wild Sarsaparilla (Aralia
nudicaulis), and Low Bush Blueberry (Vaccinium angusitfolium) and both treed and
bare Rock Barrens (Figure 1).
Environmental Impact Study 6
2 Study Approach
2.1 Collection and Review of Background Information
Existing information pertaining to the natural heritage features of the property and
the surrounding lands was obtained from the Ontario Ministry of Natural Resources
(MNR), and the Natural Heritage Information Centre (NHIC 2007). Additionally, policies
of Georgian Bay Township and the District Municipality of Muskoka were considered
where relevant to the property.
Digital Ontario Base Maps (OBM - scale 1:10,000), and colour aerial photographs
were reviewed using ArcMap GIS software. Other sources of information were consulted
as necessary (e.g., environmental reports and reference guides for this area), these
included; Ecological Survey of the Eastern Georgian Bay Coast (Jalava et al. 2005).
A review of existing information (e.g., natural heritage mapping, known flora and
fauna, existing site reports, and various remotely sensed images) associated with this area
provided an understanding through expert interpretation of the values including, but
not limited to, Significant Habitats of Threatened and Endangered Species (SHTES),
that may be found on the property. The review and preliminary habitat mapping
allowed for identification and confirmation of values efficiently during site visits.
A review of the Natural Heritage Information Centre (NHIC 2007) database
indicated that the following species area known to the greater general area;
eastern massasauga (Sistrurus catenatus catenatus) – threatened,
eastern foxsnake (Elaphe glodi) – threatened,
eastern hog-nosed snake (Heterodon platyrhinos) – threatened,
spotted turtle (Clemmys guttata) – endangered,
Blanding’s turtle (Emydoidea blandingii) – threatened,
stinkpot (Sternotherus odoratus) – threatened, and
five-lined skink (Eumeces fasciatus) - special concern
Environmental Impact Study 7
all considered Species at Risk by both the Province of Ontario and government of
Canada are known to the area.
The potential habitat for Atlantic Coastal Plains plant species exist primarily within the
shoreline habitat along parts of the west and north side of the subject property.
2.2 Natural History of Target Species at Risk
2.2.1 Eastern Massasauga
Description and Natural History:
The eastern massasauga is the only venomous snake species in Ontario. The word
‘massasauga’ is the Chippewa word for “great river-mouth”, describing the places these
snakes are often found.
The massasauga is a thick-bodied snake, tapering towards the tail to produce a well
developed rattle in adults. The colour of the massasauga ranges from grey to dark brown,
with a row of darker saddle-shaped blotches down the spine, accompanied by several
rows of smaller alternating spots on either side. The massasauga has pits between each
nostril and eye, capable of detecting thermal radiation. This enables them to detect warm-
blooded prey, and hunt at night. The eyes of this group are also unique from the circular
pupils of non-venomous species, as the pupil is a vertical slit similar to a cat. Adult
snakes generally range between 50 and 70 cm in length.
A solitary and passive creature, the massasauga prefers to remain camouflaged and
motionless. When threatened, they may defend themselves by biting (generally after a
warning rattle), and may or may not inject venom, though they tend not to attack by
choice. As an ambush predator, the rattlesnake’s strategy is to wait and strike, though
their striking distance is limited to about one-third to one-half their body length. The
massasauga’s diet consists largely of small mammals, but may include small birds as
well. Mating occurs from mid-July to late-August. Females store the sperm over-winter
and thus reproduce every other year, usually starting at the age of five.
Habitat:
Though they may occupy an extremely diverse range of habitats, massasaugas
require protection from predators and natural elements, access to sunlight and warmth, as
Environmental Impact Study 8
well as sufficient quantities of moisture. In the Georgian Bay area, perched table-rocks in
rock-outcrops provide shelter and sunlight to gravid females, tall grasses, forested areas
near clearings, wetlands are also suitable habitats for males and non-gravid females. The
massasauga shows fidelity to hibernation sites by returning to the same hibernacula each
year. The hibernaculum offers protection from the cold and allows respiration and
metabolism to slow until warmer temperatures arrive. The massasauga’s seasonal
migration away from the hibernaculum can range, but is usually close to 1 km. Similarly,
females also show fidelity to gestation sites. These areas are crucial to the development
of embryos in gravid female snakes that need to provide warm and relatively constant
temperatures. This generally involves a perched rock with vegetative covering on several
sides. Gestation sites may be shared by several females and are usually found within
500m from the female’s hibernation site, and the destruction of a single gestation site can
have impacts on the reproductive success of an entire population.
Distribution:
Locally, the massasauga inhabits areas along the eastern shores and islands of
Georgian Bay and inland about 35 km. The Georgian Bay regional population is one of
the largest across its range.
Threats:
Habitat destruction and fragmentation, motor vehicles, and human persecution, are
the largest causes of anthropogenic mortality in massasauga populations.
Status:
The massasauga is designated “threatened” by both the Committee on the Status of
Endangered Wildlife in Canada (COSEWIC) and the Province of Ontario.
2.2.2 Eastern Hog-nosed Snake
Description and Natural History:
The eastern hog-nosed snake is a thick-bodied, medium-sized snake approximately
51-115 cm in length. The characteristically upturned snout and flat head distinguish the
eastern hog-nosed from other snake species. Though extremely variant, the body pattern
of this species can be a solid colour (such as grey, brown, or black), or a series of dark
Environmental Impact Study 9
blotches over a lighter background colour. When threatened, the hog-nosed snake will
rear back and flatten its neck out, open its mouth, hiss, play dead, or use any combination
of these harmless tactics to ward off predators. During active season, the hog-nosed snake
will travel large distances (up to 6 km) to forage and locate mates. The hog-nosed snake
hibernates from October to April in mammal or self-constructed burrows, generally along
forested slopes. Mating occurs in late summer (August to September). Nesting sites are
chosen by females in early July, with preference to loose substrate, such as moist soil or
open sandy areas, they are also known to lay under table-rocks. A female will lay 10-30
eggs in a nest, and young hatch in late August to September. The hog-nosed snake has a
very specialized diet, consisting almost entirely of toads, but can include certain species
of frog.
Habitat:
In the Georgian Bay area, populations of hog-nosed snake occur along the coast and
inland over to Huntsville and into the Bancroft region. The preferred habitat of the hog-
nosed snake is dry upland areas including sandy soil, mixed forest, long grasses, and rock
outcrops, though they are also found in moist forests, and on occasion in wetlands.
Threats:
Habitat destruction and fragmentation, road mortality, and human persecution, are
the leading threats for this species. However, natural predators and collection for the pet
industry also impact the viability of the hog-nosed snake. The large distances and
relatively slow speeds of movement when crossing roads make the hog-nosed snake
particularly vulnerable to road traffic. Unfortunately widespread myths and
misconceptions about the hog-nosed snake make it despised. As a completely harmless
snake, there is no reason for the persecution.
Status:
The hog-nosed snake is designated “threatened” by both COSEWIC and the
Province of Ontario.
2.2.3 Eastern Foxsnake
Description and Natural History:
Environmental Impact Study 10
The eastern foxsnake is Ontario’s second largest snake with lengths that reach 91 to
179 cm. Adult foxsnakes are identified by their yellow or brown coloured body with
large brown or black blotched on the dorsal side of the body that alternate with smaller
blotches along the sides of the body, and weakly keeled scales. The ventral side of this
species is yellow with a black checkerboard pattern. A solid orange or brown coloured
head may also be present. This species hibernates communally from late September to
late April. Mating occurs from mid-May to mid-June; males will travel great distances
and actively seek out females. Females deposit between 7 and 20 eggs in rotting word or
debris in July. Foxsnakes primarily eat rodents (e.g., voles and mice) and birds.
Habitat:
The Georgian Bay populations of eastern foxsnakes do not stray far from the open
water of the bay. They readily swim in open water from land mass to land mass (islands
or main land), traveling large distances over an active season. Foxsnakes are frequently
found along the shoreline in rocky areas, marshes, and vegetation.
Threats:
Eastern foxsnakes main threats are loss of habitat, and fragmentation. Foxsnakes
are also commonly mistaken for rattlesnakes and this mistake sometimes results in the
unnecessary killing of this harmless snake.
Status:
The foxsnake is designated “threatened” by both COSEWIC and the Province of
Ontario.
2.2.4 Spotted Turtle
Description and Natural History:
The spotted turtle is a relatively small, semi-aquatic turtle, easily recognized by a
black carapace with yellow spots. Spotting is also present on the black skin of the face,
neck, and limbs. Adults typically measure between 9 and 13 cm. The plastron is yellow to
orange in colouration with large black markings. Adult spotted turtles emerge from
hibernation sites in mid-April, and congregate in aquatic habitats in May during the
mating season. Females nest in mid to late June, and lay 3 to 7 eggs; most females do not
Environmental Impact Study 11
produce eggs every year. Nesting habitat suitable for the spotted turtle in the Georgian
Bay area can be found under lichens and leaf litter on rock outcrops. Adults in more
terrestrial habitats may undergo a summer dormancy (i.e., inactive) period that takes
place from July until September. The spotted turtle is an omnivorous species, the diet of
which includes: vegetation such as grasses, algae, and cranberries, earthworms, insect
larvae, snails, small crustaceans, tadpoles, salamanders, and fish.
Habitat:
The populations of spotted turtles are found both inland and in shoreline regions of
Georgian Bay. In shoreline regions, spotted turtles can be found in inlets and shallow
weedy bays. They can also be found in the slow-moving shallow waters of ponds, bogs,
fens, marshes, vernal pools, and sedge meadows, both at the water’s edge and further
inland. Inland populations spend their lives in marshy waters, swamps, bogs, or other
small bodies of still water. Aquatic vegetation such as moss, sedge tussocks, cattails,
water lilies, and hydrophilic shrubs are important components of spotted turtle habitat. A
soft mucky bottom that is suitable to bury in is also a preference of these turtles.
Threats:
Loss of habitat is the major factor in the decline of spotted turtles in the Georgian
Bay area. The construction of new roads, fragmentation of wetlands, development on
lands and shorelines, drainage of wetlands, and the disturbance of sensitive areas are all
factors that attribute to habitat loss and the decline of this species. Loss of turtles to road
mortalities is also an increasing problem. People are sometimes attracted to spotted
turtles as pets and animals are moved from the wild population to a captive environment.
Status:
The spotted turtle is designated “Endangered” by both COSEWIC and the Province
of Ontario.
2.2.5 Blanding’s Turtle
Description and Natural History:
The Blanding’s turtle is a medium sized freshwater turtle, with an adult length of
12.5 to 27.4 cm. This species is easily recognizable by its large and domed greyish-brown
Environmental Impact Study 12
to black carapace that is decorated with numerous yellowish spots or streaks. These spots
or streaks generally fade as the turtle ages. The plastron is yellow in colour with black
blotches or markings on the outer posterior margins. The plastron of this species is
hinged allowing the plastron to close upwards protecting the body and head from
predators. The most distinguishing characteristic of the Blanding’s turtle is the bright
yellow lower jaw and throat that adults from both sexes possess. Although both juveniles
and adults hibernate in permanent pools, juveniles have been known to hibernate in brush
piles on dry land as well. Mating for this species takes place in early spring once the
adults emerge from hibernation. Female turtles will lay 3 to 19 eggs in late May to late
June. Females may travel multiple kilometers to find a suitable nesting site (sandy area)
and frequently cross roads to find a preferred nest site. Blanding’s turtles reach sexual
maturity around 14 years of age. They are omnivorous and have a diet that consists of
crustaceans and other invertebrates, fish, aquatic vegetation, carrion, and vegetable
debris.
Habitat:
The Georgian Bay population of Blanding’s turtles is found both inland and along
the coast. Turtles found around the shorelines of Georgian Bay prefer a habitat of shallow
weedy water but can also be found swimming in shallow sandy or mucky bays. Turtles
found both inland and on the islands of Georgian Bay prefer marshes, bogs, ponds, and
streams. Juvenile Blanding’s turtles prefer a habitat with plenty of over grown vegetation
to seek cover in.
Threats:
The largest threat faced by Blanding’s turtles and most other turtles is the destruction
of habitat. This includes the drainage of wetlands, building of roads, fragmentation of
wetlands, and the development in significant habitat. Blanding’s turtles are often and
increasingly killed on roads. Typically females searching for a nesting sites will attempt
to cross roadways, few make it across. Increasing numbers of predators is also a great
threat to nest sites of the Blanding’s turtle.
Status:
Environmental Impact Study 13
The Blanding’s turtle is designated “threatened” by both COSEWIC and the Province of
Ontario.
2.2.6 Stinkpot
Description and Natural History:
The stinkpot is a smaller turtle, measuring 5 to 13 cm in length at maturity. The shell
is smooth, highly domed, and light olive to black in colouration. Its head is dark in
colouration and has two light stripes on either side; fleshy projections are also present on
the chin and throat. This species is highly aquatic and timid, and hibernates communally
when water temperatures drop below 10ºC. Peak mating season occurs in early spring
when the turtles emerge from hibernacula. Females return to the general area to nest year
after year, and lay between 2 and 7 white hard shelled oval eggs in late June to early July.
Nest sites must be close to the water and must have a lot of exposure to sunlight. This
species is omnivorous but feeds mainly on aquatic insects, carrion, crustaceans, and
molluscs.
Habitat:
Being highly aquatic, stinkpots are rarely observed on land and prefer to live in
shallow water. The Georgian Bay population can be found in marshes, as well as along
the shoreline, in shallow vegetated back bays, and vegetated streams that feed into the
Georgian Bay. Aquatic vegetation such as reeds and lily pads, and a mucky bottom to
burrow in are important components in the stinkpot habitat. These turtles are known to
walk along the bottom of aquatic habitats rather than swimming. Generally only the
domed carapace of the stinkpot is visible buried in the mucky bottom giving the
appearance of a rock on the bottom.
Threats:
Stinkpots are at risk because of destruction to critical habitat, including: drainage of
wetlands, fragmentation of wetlands, development, and intensified fishing.
Status:
The stinkpot is designated “threatened” by both COSEWIC and the Province of
Ontario.
Environmental Impact Study 14
2.2.7 Five-lined Skink
Description and Natural History:
The five-lined skink is Ontario’s only species of lizard. Skinks can be identified by
having five yellowish or cream coloured stripes running longitudinally down the body
from the nose to the tail; juveniles can be distinguished from adults by the presence of a
bright blue tail. Five-lined skinks hibernate in small groups from early October to mid-
May. Suitable hibernation sites include old burrows, rotting stumps, wetland edges, and
rock crevices. The breeding season occurs from May to mid-June. During this time male
five-line skinks become extremely territorial and aggressively defend a territory. Female
skinks make a nesting chamber in rotting logs or may use an area under a large rock.
Clutch size ranges between 6 to 12 eggs, and are guarded by the females until the eggs
hatch in 24-55 days. Newly hatched juvenile skinks are 4 to 6 cm long and mature in their
second year. In a unique defensive behaviour skinks are able to drop their tails to escape
predators. The five-lined skink is a carnivore that spends its days foraging for insects in
grass along edges of rock outcrops, or sandy areas.
Habitat:
In the Georgian Bay area, populations of five-lined skinks can be located inland,
along shorelines, and on islands. They require sandy areas (e.g., beaches), or rock barren
habitats, and are usually close to wetlands or water.
Threats:
The most prominent threats to the five-lined skink populations are habitat destruction
and fragmentation and collection for the pet trade or personal use.
Status:
The five-lined skink is designated “Special Concern” by both COSEWIC and the
Province of Ontario.
Environmental Impact Study 15
2.3 Arial Photograph Interpretation
Aerial photographic interpretation of the subject property's biophysical features was
undertaken prior to visiting the site to carry out inspections and inventories. A colour
aerial photograph (scale 1:30,000) provided the basis for mapping the general ecological
features of the property, including vegetation communities, and potential habitats of Species
at Risk, and significant wildlife habitats. Preliminary mapping was ground-truthed and
boundaries revised as required during site visits.
2.4 Wildlife Habitats
The “Guidelines for Identifying Significant Habitat, and Significant Wildlife Habitat,
for the Massasauga in Eastern Georgian Bay and Bruce Peninsula Populations, Ontario”
were used to identify habitats of the massasauga (Massasauga Recovery Team 2006).
Descriptions of significant habitat for the hog-nosed snake, Blanding’s turtle, eastern
foxsnake, spotted turtle, stinkpot, and five-lined skink were obtained from the Ministry of
Natural Resources general description of the biology and habitat requirements in the
Parry Sound District and/or from status reports prepared for the individual species by
COSEWIC. Habitats for these species were initially assessed using existing aerial photos
and resource data, and confirmed with site visits.
Fish habitat was assessed and mapping refined as either Type 1 or Type 2 according
to the MNR fish habitat definitions as follows; Type 1 - Significant areas of emergent
and/or submergent aquatic vegetation, Type 2 - Highly variable; ranging from detritus
substrate to small aquatic vegetation beds to rocky bedrock substrate. Generally abundant
non-specific habitat utilized by a wide variety of inhabiting fish species at various life
stages (OMNR 1994).
2.5 Land Classification
To address the all the natural heritage concerns the subject property was mapped
using an ecological classification system developed specifically for the Eastern shore of
Georgian Bay (Jalava et al. 2005). This was completed to provide a general inventory of
the lands and determine if any significant communities were present that required
additional consideration. The fieldwork occurred on 14 October 2007.
Environmental Impact Study 17
3 Biophysical Features
3.1 Land Classification
3.1.1 T96, White Pine - Red Oak - Bracken Fern – Wintergreen
A large portion of the subject property consists of this common forest community.
The forest is a mix of White Pine and Red Oak, with some White Oak (Quercus alba).
The common shrubs were Common Juniper (Juniper communis) and Low-bush
Blueberry. The herb layer was comprised of Wild Sarsaparilla, Canada Mayflower, and
Bracken Fern (Pteridium aquilinum), with occasional areas of Wood Ferns (Dryopteris
sp.).
Figure 2. Photo illustrating the Common Juniper Acidic Shrub Rock Barren community.
3.1.2 P64, Common Juniper Acidic Shrub Rock Barren Type
This type of habitat was found in the central area of the subject property (Figure 1)
stretching to the south end. This community is relatively open and dominated by
Common Juniper, with White Pine and Red Oak, along with Crinkled Hairgrass
(Deschampsia flexuosa), and Poverty Oatgrass (Danthonia spicata) (Figure 2). Three
Environmental Impact Study 18
potential massasauga gestation sites were found within this type of community;
furthermore this community provides habitat for five-lined skinks.
3.1.3 P68B, White Pine - Oak Treed Acidic Rock Barren
White Pine, and to a lesser extent Red Oak dominant the rock barrens when trees
are present. The low shrub layer is dominated by Common Juniper and Low-bush
Blueberry. The most common herbaceous plants of the rock barrens on the subject
property are Crinkled Hair Grass and Poverty Oat Grass. Lichen and mosses, are also
common on these rock barrens.
3.1.4 P1, Acidic Open Bedrock Shore Type
Open bedrock shoreline communities occur along the shores of the subject property.
These communities are sparsely vegetated areas comprised of lichen and moss species,
and the occasional shrub (e.g., Common Juniper (Juniper communis)), herb, or stunted
pine (Figure 1).
Figure 3. Photo illustrating a P1, Acidic Open Bedrock Shore community.
Environmental Impact Study 19
3.1.5 T119C, Sugar Maple - Red Oak – Basswood – Red Maple
This forest community was a mix of Sugar Maple, and Red Oak, with some
Basswood (Tilia americana). The sampling layer consists of Sugar Maple and Red Maple
(Acer rubrum). Striped Maple (Acer pensylvanicum) occurs as a tall shrub along with
other deciduous tree seedlings. The herb layer was comprised of Wild Sarsaparilla,
Canada Mayflower, Bracken Fern, and Wood Fern.

Figure 5. Photo illustrating a W188, White Pine Mineral Coniferous Swamp.
3.1.6 W188, White Pine Mineral Coniferous Swamp
White Pine is the dominant tree species, the shrub layers are comprised of Mountain
Holly (Nemopanthus mucronatus), Speckled Alder (Alnus incana), and Sheep Laurel
(Kalmia angustifolia). The few herbs present usually consist of Wood Ferns, and Three-
leaved Solomon’s-seal (Maianthemum trifolium). Massasauga hibernation habitat was
found in this community type (see Species at Risk Habitat section below).
Environmental Impact Study 21
Figure 6. Photo illustrating a W275, Narrow-leaved Sedge Mineral Meadow Marsh community.
3.1.7 W275, Narrow-leaved Sedge Mineral Meadow Marsh
A meadow marsh with mineral substrate occurs along and adjacent to the eastern
boundary of the subject property (Figure 1). The area was quite dry due to the low
Georgian Bay water levels; consequently a well developed shrub layer of Sweet Gale
(Myrica gale) and Speckled Alder occurs at the upland-wetland ecotone. The dominant
plants in this community include, Tussock Sedge (Carex stricta), and Woolgrass (Scirpus
cyperinus). Other graminoids, included Beaked Sedge (Carex utriculata), Canada Blue-
joint (Calamagrostis canadensis), and Lake-bank Sedge (Carex lacustris). This area
would be used by massasaugas, foxsnakes, and Blanding’s turtles thus the area should be
protected from development.

with a small fringe of Coastal Meadow Marsh.
3.1.8 W330A, Water-shield – Water-lily Floating-leaved Shallow Aquatic with a small
fringe of Coastal Meadow Marsh
Water-shield is dominant with White Water-lily (Nymphaea odorata) in a small
community on the north side of the subject property. Co-dominants and secondary
species include Canada Blue-joint, Three-way Sedge (Dulichium arundinaceum), Lake-
bank Sedge, Beaked Sedge, Creeping Spike-rush (Eleocharis smallii), Sweet Gale,
Pickerel Weed (Pontederia cordata), Floating-leaved Burreed (Sparganium fluctuans),
and Cardinal Flower (Lobelia cardinalis)(Figure 7). This area could be used by
Blanding’s turtles, stinkpots, massasauga, foxsnakes, and spotted turtles thus the area
should be protected from development.
Environmental Impact Study 23
Figure 8. Photo illustrating the narrow strip of Georgian Bay Coastal Acidic Mineral Meadow
Marsh community.
3.1.9 W271B, Georgian Bay Coastal Acidic Mineral Meadow Marsh
A meadow marsh with mineral substrate occurs in a couple areas along the north
shores of the subject property and a narrow strip occurs along the west shore (Figure 1).
The area was quite dry due to the low Georgian Bay water levels; consequently a shrub
fringe of Sweet Gale occurs at the upland-wetland ecotone. The dominant plants in this
community are Canada Blue-joint and Soft Rush (Juncus effuses). Co-dominants and
secondary species include, Tussock Sedge, Blueflag (Iris versicolor), Three-way Sedge ,
Lake-bank Sedge, Spoon-leaved Sundew (Drosera intermedia). Within this community
are habitats where Atlantic Coastal Plaines Flora can be found, these areas are
identified in Figure 9.
Environmental Impact Study 25
3.2 Species at Risk Habitat
3.2.1 Eastern Massasauga
Massasaugas in the Georgian Bay region can be found hibernating in the following
types of habitats, conifer, mixed, or shrub swamps and swales, poor fens, or depressions
in bedrock terrain where water saturated soils have supported the development of
vegetation communities characterized by sparse trees or shrubs with sphagnum moss or
sedge hummock ground cover (Massasauga Recovery Team 2006). The property was
assessed for these types of habitats. One of these habitat types was identified during fall
fieldwork. The potential massasauga hibernation habitat was assessed as a medium
quality perched bog massasauga hibernation site (Figure 5, Figure 9). Species at Risk
Consulting and Ecological Services recommends that High and Medium quality habitats
be considered Significant Habitat of Threatened and Endangered species (SHTES), and
Low quality habitats be considered Significant Wildlife Habitat (SWH). This area has
been classed as medium quality and thus should be protected from development and be
zoned Environmental Protection (Table 1).
Massasaugas also require gestations sites to successfully reproduce. Gestation sites
are often found in Rock Barren habitats in the Georgian Bay region (Massasauga
Recovery Team 2006). The preliminary assessment of the subject property identified a
number of Rock Barren habitats, field visits in the fall confirmed the existence of
potential gestation sites (Table 1, Figure 10), however a large portion of the Rock Barren
habitat do not contain the necessary micro habitats to be considered Significant Habitat of
the massasauga. The potential gestation sites are identified in Figure 9 along with a 10m
“non development” buffer around them, it is recommended that these buffered areas be
protected from devolvement and be zoned Environmental Protection.
Wetlands on or adjacent to the property, large enough to be considered as mating
habitat (Significant Wildlife Habitat) for massasaugas using the habitat guidelines, do
occur (Table 1, Figure 9), these habitats also represent Significant Habitat for other
Species at Risk found in the area (see below).

property.
3.2.2 Eastern Hog-nosed Snake
No known hibernation sites for hog-nosed snakes occur on this property. There are
no natural open dry sandy areas for nesting opportunities for the hog-nosed snake on the
subject property (Table 1). Furthermore, there are no coniferous covered slopes large
enough to potentially be hibernation sites for hog-nosed snakes. Therefore, no significant
habitat as it relates to the eastern hog-nosed snake exists on this property.
3.2.3 Eastern Foxsnake
There are no known hibernation sites for foxsnakes on this property. The property
was thoroughly searched for potential habitat characteristics of foxsnake hibernation sites
(e.g., deep cracks in rocks, rocky ledges, etc.). One area was located along the southern
edge of the subject property (Figure 9, Figure 11) this area also contains habitats that
could function as a shedding site or basking site. Because of the difficulty in building in
these types of areas, these steep sloped areas are often removed from development by
local by-laws, this type of habitat is rarely impacted. However, this habitat should receive
Environmental Impact Study 27
additional protection and be protected from incompatible development. The area that
should be considered SHTES and protected is identified in Figure 9. The wetlands
adjacent to the property at the north end (Figure 6, Figure 7) of the property represents
foraging habitat of the foxsnake and should be protected from incompatible development
as well (Table 1, Figure 9).

3.2.4 Blanding’s Turtle
No Blanding’s turtles were found during site inspections. There are no natural open
dry sandy areas for nesting opportunities for Blanding’s turtles on the subject property
(Table 1). The wetlands habitat in the northeast section of the subject property (Figure 6,
Figure 7) identified in Figure 9 should be considered foraging, basking, and mating
habitat of the Blanding’s turtle and should be considered Significant Habitat of
Threatened and Endangered Species (SHTES), and should be protected from
incompatible developments.

3.2.5 Spotted Turtle
The type of wetlands that occur on and around the subject property are not indicative
of the spotted turtle’s preferred habitat (Table 1). However, the habitat areas that may
occasionally be used by spotted turtles are proposed for protection due to the presence of
a number of other species at risk that are known to utilize the available types of wetland
habitat extensively.
3.2.6 Stinkpot
No stinkpots were recorded along the shorelines of the subject property during the
fieldwork; however the adjacent wetlands along the northeast section (Figure 6, Figure 7)
of the subject property identified in Figure 9 may provide stinkpots with foraging and
hibernation habitat and should be considered SHTES (Table 1). The presence of stinkpot
habitat is another factor in determining that the wetland habitats occurring along the north
side of property require protection from incompatible development.
3.2.7 Five-lined Skink
No skinks were documented on this property during the fieldwork component.
However, skink habitat exists in association with Massasauga habitat and will
consequently receive habitat protection (Table 1).
3.3 Fish Habitat
The Township of Georgian Bay had identified a large section of Type 1 Fish Habitat
along the northern shoreline (Figure 9), this work has confirmed that area and included
some additional areas that should be mapped as Type 1, the rest of the shoreline of the
subject property should be considered Type 2; in order not to complicate the map of
significant habitats, Type 2 Fish Habitat was not included. Currently a portion of the
Type 1 Fish Habitat is at or above the present water level, but if or when the water levels
increase this exposed area has a lot of potential to be fish habitat, currently the exposed
area is a mineral coastal meadow marsh.
3.4 Atlantic Coastal Plains Flora Areas
The areas identified as potential habitats for these rare plants should be protected
from incompatible developments (i.e., dredging, infilling, beach creation, unwarranted
Environmental Impact Study 29
shoreline stabilization, docks, removable of vegetation, etc.), and should be considered
Significant Wildlife Habitat (Figure 9).
3.4.1 Prairie Warbler
The property has a limited amount of Prairie Warbler habitat; with most of the
habitat found on the south-eastern half. Because Prairie Warblers prefer White Pine –
Red Oak – Rock Barren habitat, the bird is relatively common in Southern Georgian Bay.
The habitat on this property is away from potential development areas and corresponds
well with the proposed habitat protection for the massasauga (Figure 9). Thus this rare
species of bird will receive habitat protection through indirect means on this subject
property.

4 Environmental Impact Statement
4.1 Species at Risk
The areas identified as Significant Habitat of Threatened and Endangered Species
(SHTES) should be protected from all development and habitat alteration (e.g., filling
any of the identified areas, dredging in any of the identified areas, removing of vegetation
from the shoreline/wetland edge, trails of any kind within this habitat, buildings,
structures (i.e., docks), and facilities).
If the areas identified as potential Species at Risk habitats and associated buffers are
protected from incompatible developments (Figure 9), then the proposed application
including the severing of the existing lot, and the building of residences and associated
facilities (e.g., septic system, docks, etc.), will result in no significant habitat or
populations of the identified threatened and endangered species being impacted, nor will
any significant negative effects occur on the identified Significant Wildlife Habitat or
species identified as potentially occurring on the subject property.
5 Summary and Conclusions
In conclusion, Species at Risk Consulting and Ecological Services has identified a
number of habitats and natural features worthy of protection on the subject property and
has made recommendations that if agree to and the appropriate planning action taken will
ensure the long-term protection of the Significant Habitats of the identified Threatened
and Endangered Species, and the Significant Wildlife Habitat.
