Wisconsin's rare animals

All of Wisconsin's rare species are found on the Natural heritage working list. Species become rare for a number of reasons, including habitat loss, habitat degradation, highly specialized habitat needs, disturbance sensitivity, genetic problems, exploitation, persecution, predation, competition and parasitism. Some rare species are present here at the edges of their main ranges. Invasive species and climate change are also impacting rare species and expected to become even bigger factors in the future.
