Natural Resource Management

Natural resource managers can assess the environmental health of Tonto National Monument by monitoring and studying the plant and animal species that occupy it. Park staff and partners have worked on several projects to locate, document, and study plants and animals in the monument. Motion-sensor cameras help document species such as bears and mountain lions. Researchers have captured and implanted radio transmitters into snakes and Gila monsters in order to track their activities and learn more about their ranges and habitats. The cameras and transmitters also allow researchers to study behavior and monitor the health of each individual. Some key projects are described below.

Citizen Science-Based Environmental Monitoring

Park visitors can help staff monitor ongoing restoration efforts along the Lower Cliff Dwelling trail. A photo station has been placed along the trail for visitors to help document how vegetation changes over time after the 2019 Woodbury Fire.

Arizona Black Rattlesnake Research

Despite the species' limited range, basic biological information needed to make management decisions is lacking for most Arizona black rattlesnake populations. To address this need, U.S. Geological Survey (USGS) scientists conduced research on the species in Arizona national park units from 2003 to 2005. The research examined relative population abundance, movement patterns, range requirements, dietary habits, and winter and summer habitat.

Gila Monster Research

Despite public fascination with the species, relatively little is known about the ecology and behavior of the Gila Monster in the wild. For this reason, managers at Tonto National Monument contacted the U.S. Geological Survey to investigate why Gila monsters were seen in developed areas of the park, particularly crossing the main road.
