1 Plant Selection Guideline Species List for Planting Plans within the Credit River Credit Valley Conservation (CVC) promotes the protection and enhancement of native plant biodiversity by requiring the use of native species that are common to the watershed in our regulated area. In areas that are not regulated, CVC recommends the use of native species that are common to the watershed. The following list can be used to select species for designing planting plans for natural restoration projects, mitigation plans and stormwater management pond blocks across the Credit River. The use of this list ensures that plantings are successful, fit in well with existing natural areas and enhance the ecological function of the natural heritage system of the Credit River. The list also includes a which can be used with Table 1 below to determine the associated soil moisture regime preferences for each species. There are two ecoregions within the Credit River : 6E - Lake Simcoe - Rideau Ecoregion and 7E - Lake Erie - Lake Ontario. Each ecoregion is characterized by a distinct biological response (i.e. species and communities) to the environmental conditions (i.e. climate and geology) associated with that region. This list provides guidance on which species are appropriate for planting in each of these ecoregions. To simplify implementation and ensure consistency within individual municipalities, the watershed has been divided into two zones ( and ) that roughly correspond to the boundaries of the ecoregions. The includes the City of Mississauga, City of Brampton, Town of Oakville and Town of Milton. The includes the Town of Halton Hills, Town of Caledon, Town of Orangeville, Town of Erin, Township of East Garafraxa, Township of Amaranth, and Town of Mono. CVC staff have identified a selection of herbaceous, sedges, rushes, emergent and aquatic plants that appear to be successful in SWM ponds, based on a review of SWM ponds within our watershed and the following reports: Performance Assessment of a Highway Stormwater Quality Detention Pond (SWAMP 2003) and Town of Aurora Stormwater Ponds Vegetation & Wildlife Study (Aurora Environmental Advisory Committee 2007). These species are highlighted in green in the Plant Selection Guideline List. A list of acceptable cover crops is included on page 11. To obtain a workable version of this document in excel format please contact a CVC Planning - Ecologist.
