In order to conserve or restore native imperiled species, natural resource managers must understand the ecology, or behavior and inter-species relationships, of these species. With this information, environmental managers can identify essential habitat supporting the key life stages of imperiled species. Scientists at GLSC conduct science on the spatial movement and habitat preferences of lake sturgeon, lake trout, and lake whitefish. Some study recruitment dynamics of cisco, an important native prey fish targeted for restoration. Others study the factors affecting the distribution and success of native plants, such as the endangered Pitcher’s thistle that resides in Great Lakes dune ecosystems.
