Subwatershed: Beaver Dam Creek and Oil Mill Creek<br />

Approx. Size: 190 hectares<br />

General Summary: It is bounded by Main Street East/Highway 3 on the north, <strong>Lake</strong><br />

<strong>Erie</strong> to the south, Weaver Road to the west and Pinecrest Road to the east. The most<br />

common community noted was Deciduous Swamp dominated by Green, Swamp Maple,<br />

and Red Maple with White Elm. The understory was largely Spicebush, Climbing<br />

Poison-ivy, Common Buckthorn, and Gray Dogwood. The herbaceous layer was a mix<br />

of Spotted Touch-me-not, Fowl Manna Grass, Radiate Sedge, Stout Woodreed, Awlfruited<br />

Sedge, Goldenrod species, and Western Poison-ivy. There are a total of 167<br />

Name: Old Mill Creek Wetlands and Dunes<br />

Site ID: PC-14-00-00-00-00<br />

Municipality: City of Port Colborne<br />

Subwatershed: Old Mill Creek and Bearss Drain.<br />

Approx. Size: 129 hectares<br />

General Summary: This site lies between Highway # 3 to the north, <strong>Lake</strong> <strong>Erie</strong> to the<br />

south, Pinecrest Road to the west, and Bearss Drain to the east. The first community is<br />

dominated by Swamp Maple or Red Maple with numerous large spreading trees, some<br />

over 1m diameter. The major associate throughout this community is Green Ash which<br />

dominates some patches. White Elm, Shagbark Hickory and occasionally Bitternut<br />

Hickory or Yellow Birch are found as associates. There were pockets with deep organics<br />

which measured more than 30cm where the wetland and dune meet. A low, stabilized<br />

back-dune community dominated by very large diameter, mature Red Oaks with patches<br />

of American Beech (some very, very large, almost 1m dia., and healthy trees) was also<br />

documented. A few Yellow Birch were recorded near the wetland edge, along with a<br />

Black Cherry and one, approx. 50cm dia., Tulip Tree. A total of 38 taxa were<br />

documented at this site.<br />

This site is also in part designated as Oil Mill Creek Wetland Complex LSW and<br />

Empire Beach Backshore Basin Forest Life Science ANSI and PSW.<br />

Site ID: PC-11-00-00-00-00<br />

Municipality: City of Port Colborne<br />

Subwatershed: Bearss Drain and Beaver Dam Creek P.C.<br />

Approx. Size: 123 hectares<br />

General Summary: This site is situated below Humberstone Marsh. There is a very<br />

successional swamp forest regenerating around upland patches of plantation (plantation<br />

includes open meadow patches\Grey Dogwood thicket or closed plantation). A strip of<br />

old field meadow stretches from east to west along the northern margin of the natural<br />

area. This also supports an inclusion of Narrow-leaved Cattail Shallow Marsh. To the<br />

south of the forested polygons 1 & 2, a dry-moist old field has also succeeded with<br />

numerous meadow marsh slough communities. The study site also has many large<br />

diameter oaks. A total of 206 taxa were collected for this study site.<br />

This site is also in part designated as Humberstone Southwest Wetland Complex<br />

LSW.<br />
