In Order to Care, You Need to Know What's There

Across the Sonoran Desert and up to the southwestern sky islands, ecologists from the Sonoran Desert Network collect information on plants, water, air, birds, and climate. Back at the office, they analyze the data and share the results with park managers.

Knowing which key resources are found in their parks, and whether those resources are stable or changing, can help park managers to make sound decisions about the future. Through our work, we help develop a stronger scientific basis for stewardship and management of natural resources across the National Park System. In this way, we help to ensure that our national natural treasures are conserved, unimpaired, for future generations.

The Sonoran Desert Network includes 11 national park units: 10 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).
