The Mojave Desert Inventory & Monitoring Network (MOJN) is comprised of seven national park units located in southern Nevada, Arizona, and California. Multiple ecosystems are represented across MOJN parks including desert, lakes, springs, and montane island habitats.

The Network is charged with creating inventories of its species and natural features as well as monitoring trends and issues. These parks and their partners are dedicated to understanding and preserving the region's unique resources through science and education.

This web site delivers information about these resources, the Network's Inventory & Monitoring Program, and the scientific activities underway. Learn more about specific topics by exploring the links on the left or visit the park units pages to discover the particular resources found at each of these special places.
