Description du site
The Twelve Mile Creek Headwater Forests (the Fonthill Sandhill Valleys, Short Hills Provincial Park, Decew Gorge, North Pelham Valley, Effingham Forest, and St. John?s Valley) are situated near the mouth of the Short Hills Valley to the north and west of the cities of Thorold and St. Catharines. Most of the valley is covered by glacial debris from the Fonthill Kame, and is highly dissected by Twelve Mile Creek and its tributaries, creating a complex series of uplands, ridges, and valleys (some up to 30 m deep). The upper valley slopes support beech forests, while the lower slopes are dominated by Sugar Maple with scattered Tulip Trees, and mixed forests of Eastern Hemlock, Sugar Maple and American Beech. The bottomlands have open seeps with Skunk Cabbage, meadow marshes, thicket swamps of Spicebush and alders, and forests of walnut, Red and Sugar maples, Yellow Birch and White Pine. In addition to birds, the headwater forests support a rich assemblage of flora and fauna. Detailed botanical surveys within each of the forest blocks have recorded between 400 and 500 vascular plant species, and 9 to 15 species of nationally and/or provincially rare plants. The provincially Vulnerable Southern Flying Squirrel has also been recorded in the North Pelham Valley.
