Ecology Program

The mission of the Nevada Division of Natural Heritage (NDNH) includes the coordination of resource needs of Nevada's diverse biological heritage with human activities. Since species do not live in isolation from each other or the landscape, this coordination naturally involves many ecological issues. The emphasis of ecology at NDNH is mapping and tracking at-risk vegetation types and the factors contributing to risks. Plant communities can be used to assess the condition of ecosystems and the landscape. Plant communities also provide habitat for the thousands of native animals. Through a better understanding of plant communities across the landscape, we can be better prepared to deal with issues of rare species as well as a variety of human issues that involve land use.
