Chase Lake National Wildlife Refuge NEON - United States of America
Chase Lake National Wildlife Refuge NEON
United States of America
The Woodworth (WOOD) core terrestrial field site is located approximately 100 miles northeast of Bismarck, North Dakota in Stuntsman County. It is encompassed in the Northern Plains Domain, which includes a patchwork of grasslands, agricultural, and wetland/aquatic communities embedded in a matrix of small agrarian communities. This site is a restored praire located in an undulating matrix of small lakes, ponds, and ephemeral praire potholes formed by glaciers 10,000 years ago. It is managed by the U.S. Geological Survey and the U.S. Fish and Wildlife Service, and is part of the larger Chase Lake National Wildlife Refuge (NWR). Remote sensing surveys of this field site collect lidar, spectrometer and high-resolution RGB camera data. The flux/meteorological tower at this site is 26 with 4 measurement levels. The tower top extends above the vegetation canopy to allow sensors mounted at the top and along the tower to capture the full profile of atmospheric conditions from the top of the vegetation canopy to the ground. The tower collects physical and chemical properties of atmosphere-related processes, such as humidity, wind, and net ecosystem gas exchange. Precipitation data are collected by a tipping bucket at the top of the tower and a series of throughfalls located in the soil array. This site has five soil plots placed in an array within the airshed of the flux tower. Field ecologists collect the following types of observational data at this site: Terrestrial organisms (birds, ground beetles, mosquitoes, plants, small mammals, soil microbes, ticks), Biogeochemical data, and soil data.The WOOD terrestrial site produces 110 data products.
General Characteristics, Purpose, History
Woodworth provides a baseline understanding of a core wildland system that is historically representative of the region and provides meaningful comparison to the other sites in the region that are managed with different degrees of grazing intensity. While there is little urban development in the area, this site is paired with other grassland sites within the NEON continental design: it provides a contrast to sites that may receive chemical climate inputs from agronomic practices, as well as sites from nearby growing urban environments. The Woodworth site also provides an understanding of tall grass prairie environments and serves as a benchmark for detecting and exploring the causes and consequences of environmental change taking place throughout the grasslands of the Northern Plains Domain, with results relevant to semi-arid grassland ecosystems worldwide.
