Reynolds Creek is home to five CORE sites. These CORE sites are heavily instrumented areas carefully distributed across the climatic and elevation gradients of the Reynolds Creek watershed. They provide detailed datasets which scientists use to create models of sagebrush steppe ecosystems. These models are then used to help make predictions about similar ecosystems in other areas of the U.S and the world. In the video below, Dr. Aaron Fellows explains the types of measurements made at CORE sites and why making such detailed measurements of sagebrush steppe ecosystems is helpful to all scientists.
