General Summary: This study site follows Lyons Creek from the Welland Canal to the Welland River at Chippawa. It consists of the floodplain areas and closely associated woodlands. This study site is unique in that it is basically limited to the floodplain communities and closely associated woodlands. Therefore, the majority of the communities noted were either, Shallow Marsh, Thicket Swamp, or Deciduous Swamp. The Shallow Marsh communities were characterized by Narrow-leaved Cattail, Broad-leaved Cattail, Common Reed, and Dotted Smartweed, with floating communities of Lesser Duckweed, and Star Duckweed. The Bur-reed marshes were a frequent component in areas with slightly deeper water, typically just beyond the limits of cattails. Buttonbush and Silky Dogwood were common on the banks. The Thicket Swamp communities noted were dominated by Buttonbush and Dogwood with some Green Ash trees scattered around. The herbaceous layer was mostly Canada Blue-joint, Fringed Loosestrife, Arrow-leaved Tearthumb, and Clearweed. The Deciduous Swamps were largely Dogwood and Willow with patches of Green Ash, Red Maple, Pin Oak, and White Swamp Oak. The understory was usually a mix of Buttonbush and Dogwood with a herbaceous layer of Sedges, Avens and Moneywort. In the more upland areas of the floodplain, there were Deciduous Forest communities dominated by Red Oak, Sugar Maple, Shagbark Hickory and Hop Hornbeam. There are a total of 418 recorded taxa for this study site. This site is also in part designated as Lyon’s Creek Provincially Significant Wetland and Lyon’s Creek Floodplain Wetland ANSI (both are not in the LWR study area).

Lower Welland River Study Area Characterization Report Approximate. Size: 490 Hectares Subwatershed: The north/west section of this study site drains to Thompsons Creek, the north/east section drains to the Chippawa Power Canal, and a small portion in the south drains directly to the Welland River East. General Summary: This study site is bound by McLeod Road to the north, Chippawa Creek Road/ Welland River to the south, Thorold Townline Road to the west, and Montrose Road/ QEW to the east. A diversity of Deciduous Forests were recorded for this study site. These were generally associated with upland, or ridge areas within the larger forest patches. Drier sites include associations characterized by American Beech, Red Oak, Sugar Maple, White Ash, Hop Hornbeam, and Black Cherry. Fresh-moist sites include Basswood, Red Maple, Sugar Maple, White Elm, and Bur Oak. Groundcover in the upland forest communities was varied according to the microtopography. Common species observed included Spotted Crane‟s-bill, Wild Blue Phlox, Jack-in-the-pulpit, Western Poison Ivy, Mayapple, Canada Enchanter's Nightshade, and Virginia Creeper. The Deciduous Thicket Communities were dominated by Gray Dogwood in association with various species of Hawthorn. The Deciduous Swamp communities were characterized by mature Red Maple and Silver Maple co-dominates, or Pin Oak. Other canopy species included White Elm and Swamp White Oak. Understory species included Spicebush with Sensitive Fern, Skunk Cabbage, and Spotted Touch-me-not. Some sloughs supported Bur-reed Shallow Marsh communities while others favoured Duck-weed Floating Aquatic communities. One particular slough pond supported an organic Buttonbush Thicket Swamp. There are a total of 406 recorded taxa for this study site. This site is also in part designated as Thompsons Creek Wetland PSW and Warren Creek Wetland Complex PSW. Name: Dufferin Islands – Queen Victoria Park – Niagara Gorge Formerly Dufferin Islands-Victoria Park-Niagara Gorge (Brady, et al., 1980) Site I.D.:NF-03-00-00-00-00 Municipality: City of Niagara Falls Approximate. Size: 59 Hectares Subwatershed: This study site drains directly to the Niagara River. General Summary: This Study Site follows the Niagara River on Niagara Parks Commission property from Upper Rapids Road in the south to the Whirlpool Bridge in the north. It is bound by the Niagara River to the east, Portage Road/Fallsview Boulevard/Victoria Avenue to the west and Niagara River Parkway to the south and north. The Natural Areas Inventory field crews only visited the forested areas of Dufferin Islands. The Deciduous Forest communities of this study site are characterized by Sugar Maple, and Red Oak. Common understory associates are Eastern Hemlock, and Spicebush. There are a total of 137 recorded taxa for this study site.
