Brian Powell papers

This collection includes groupings of data collected by Brian Powell and others in relation to the Sonoran Desert Inventory and Monitoring Network. Ecologists working with the Sonoran Desert Inventory and Monitoring Network aim to collect pertinent information on plants, water, air, birds, and climate by making observations at eleven National Park Service units. These inventories, collected by Powell, include information on birds, amphibians and reptiles (identified as 'herps' in the inventories), mammals, and plants at different locations across Arizona.
