Urban Wetland Connectivity
A project to help maintain amphibian diversity and increase amphibian abundance in the urban environment
The Issue / Idea
How can municipalities support urban amphibian populations?
The goal of this project was to provide information to The City of Calgary to help maintain amphibian diversity and increase amphibian abundance in the urban environment. Three amphibian species, wood frog (Lithobates sylvaticus), boreal chorus frog (Pseudacris maculata) and tiger salamander (Ambystoma mavortium) currently make Calgary their home. Key concerns for amphibians in Calgary are the impacts of wetland loss, wetland degradation, and fragmentation of the wetland network. We sought to understand which wetlands support amphibians and where amphibians are moving between wetlands in Calgary.
The modelling products include habitat suitability indices, connectivity models, and centrality and barrier maps designed to inform planning, management and restoration of the wetland network to support amphibians in Calgary. For this project, natural wetlands, modified wetlands and stormwater ponds were all included in modelling and are referred to in this report generically as wetlands.
