Because the sites in our network focus on long-term ecological processes, the continuity of our efforts is critical to tracking and understanding environmental change. During 2013, disruptions in the federal government’s support for research challenged our ability to maintain long-term experiments and observations. Working with the National Science Foundation (NSF), LTER sites successfully met this challenge and continued to produce important new insights into the way our nation’s key ecosystems function.
