The Mojave Desert Inventory & Monitoring Network (MOJN) is one of 32 monitoring networks across the NPS. These Networks were established to collect and analyze data about park natural resource conditions, take inventory of park species and natural features such as springs and streams, and monitor changes in these valuable resources over time.

MOJN is comprised of eight national park units located within the Mojave and Great Basin deserts of Nevada, Arizona, and California. The MOJN parks encompass the largest total area of all the networks in the lower 48 states (nearly 3.3 million hectares). Across these park units, MOJN I&M monitors the health and quality of five different vegetation communities, six subalpine lakes, and several hundred water features including oases, springs, streams, seeps, and wells.

This website delivers information about the Network's Inventory & Monitoring Program, the resources we monitor within the MOJN parks, and the scientific activities underway to help inform park managers and decision makers about the health of their natural resources. Learn more about specific topics by exploring the links on the left or visit the Network Parks page to learn more about these parks and discover the unique resources found at each of these special places.

Paleontological resource inventory and monitoring

Paleontological Inventory and Monitoring Report Cover

Paleontological resources (fossils) are any remains of past life preserved in a geologic context. Despite the abundance and diversity of these resources throughout the National Park Service, until recently, few parks have had adequate baseline paleontological resource data.
