Climate change presents significant risks to our nation’s natural and cultural resources. In order to meet the challenge of managing national parks in the face of global climate change, it is critical that the National Park Service has high-quality, natural resource monitoring and inventory data to track changes as they occur. The Greater Yellowstone Inventory and Monitoring Network (GRYN) is collaborating with the Rocky Mountain (ROMN) and Upper Columbia Basin (UCBN) networks to implement a High Elevation Climate Change Response Strategy. This strategy focuses on high elevation parks and enhances natural resource monitoring of select vital signs, including climate, pika, five-needle pine, snowpack and phenology, and alpine habitats. These data and other vital signs will be used to evaluate and report status and trends of park resources for the purpose of facilitating adaptation planning and management.
