Conservation Status

Determining which species and ecosystems are thriving and which are rare or declining is crucial for targeting conservation toward elements of biodiversity in greatest need. NatureServe and its network members use a suite of factors to assess the conservation status of plants, animals, and ecological systems and communities.
