The EcoTrends project is funded by the National Science Foundation (NSF) and the USDA Agricultural Research Service (USDA-ARS) Jornada Experimental Range. Collaborators include: the Long-Term Ecological Research (LTER) Network Office, USDA-ARS, USDA Forest Service (USDA-FS), National Center for Ecological Analysis and Synthesis (NCEAS), Department of Energy (DOE), US Geological Survey (USGS), New Mexico State University (NMSU), Ecological Society of America (ESA), and state institutions. This project would not be possible without the continued assistance and involvement of scientists, information managers, support staff, and students from each long-term site.
