Natural & Cultural Resources Vital Signs

Yellowstone National Park’s “Natural Resource Vital Signs” report is a valuable tool used to assist park managers and scientists more fully understand the status of important indicators of resource condition. The report published by the Yellowstone Center for Resources (YCR) helps inform resource management decisions and supports ongoing and future research needs. The first report was conducted and published in 2008.

Park scientists and their cooperators report on data from more than two dozen indicators to study the influences, both inside and outside of the park, that affect Yellowstone’s overall ecological status and the condition of cultural resources. Ecological indicators include ecosystem processes such as wildland fire, as well as, the status of native species and stressors such as wildlife disease and non-native species.
