The Sonoran Desert Network (SODN) is one of 32 National Park Service (NPS) inventory and monitoring networks nationwide. These networks use vital signs monitoring to assess the condition of park ecosystems. The goal is to develop a stronger scientific basis for stewardship and management of natural resources across the National Park System.

The Sonoran Desert Network consists of 10 national park units in central and southern Arizona and 1 unit in southwestern New Mexico. These parks are characteristic of two ecoregions: the upper Sonoran subdivision of the Sonoran Desert Ecoregion and the Apache Highlands Ecoregion. SODN parks range in size from half a square mile to 517 square miles (147 to 133,882 hectares).

This web site delivers information about these resources and the scientific activities underway in the SODN. Learn more about what we're doing by exploring the links on the left or visit our park unit pages to find out about the resources found at each of these special places.

Climate Change Briefs

Climate Change BriefsA recent study of 289 national park units (Monahan and Fisichelli 2014) found that in the majority of those parks, recent temperatures (past 30 years) were warmer than those experienced in the last century. Information specific to each of the 11 Sonoran Desert Network parks can be found in a set of briefs derived from the article.
