The Barrie Creeks, Lovers Creek and Hewitt’s Creek Subwatershed Plan Figure 6-9: Wetland patch size distribution in the Lovers Creek subwatershed. There are only eight wetland patches remaining in the Hewitt’s Creek subwatershed, totalling 103.7 ha (or 5.9% of the landscape) (Figure 6-7, Figure 6-10). The wetland composition of this subwatershed is almost entirely dominated by two wetlands – the St Paul’s Swamp wetland complex, located where two branches of the creek merge, and an unevaluated wetland immediately north of it. Together, these two remnants represent over 90% of the total wetland in this subwatershed. Chapter 6: Terrestrial Natural Heritage 277
The Barrie Creeks, Lovers Creek and Hewitt’s Creek Subwatershed Plan Figure 6-10: Wetland patch size distribution in the Hewitt’s Creek subwatershed. Again, like woodlands, the physical connections between individual wetland patches are extremely important for some species. In the case of wetlands specifically, many species of turtles, frogs, and salamanders require both upland and wetland habitat to meet the needs of their breeding cycle. Preserving these species in a rural-urban landscape like that of these subwatersheds requires that both habitat types, as well as the physical connectivity between them, be protected. 6.2.3 Valleylands A valleyland is a natural depression in the landscape that is often, but not always, associated with a river or stream. Valleylands are an important part of the framework of a watershed as the landscape is generally a mosaic of valleylands and tablelands. Valleylands provide numerous functions for an ecosystem. These include (OMNR, 2010): • Ecological Values: dispersal and migration of wildlife, microclimate for plant communities • Hydrological Values: movement of surface water, ground water discharge areas, transport of sediment and nutrients, often associated with floodplains • Cultural values: location of aboriginal travel routes, influence current development patterns Chapter 6: Terrestrial Natural Heritage 278
