Contamination and Wildlife Communities in Stormwater Deterntion Ponds in Guelph and the Greater Toronto Area, Ontario, 1997 and 1998. Part I-- Wildlife Communities

摘要

There is very little information about the wildlife utilization of stormwater detention ponds although such ponds often self-seed into wetland habitats. To inventory wildlife utilizing stormwater ponds, a study was performed in 1997 and 1998 of 15 stormwater ponds and one natural wetland varying inage from 3 to 22 years in the Guelph and the Greater Toronto Area (GTA) in Ontario, Canada. Seven of the stormwater ponds were primarily open water with the aquatic vegetation accounting for less than 50/100 of the surface area. However, 90/100 of the surface area of four ponds was covered in aquatic vegetation. The surface area of those ponds covered with vegetation was positively correlated with total organic carbon and copper concentrations in sediment.
