This is the AmeriFlux version of the carbon flux data for the site US-xSC NEON Smithsonian Conservation Biology Institute (SCBI). Site Description - The Smithsonian Conservation Biology Institute (SCBI) site is a mid-continent forested eastern deciduous site, species include Oaks, Hickories, and Ash, and contains well defined ground cover and understory strata.
This is the AmeriFlux version of the carbon flux data for the site US-xSJ NEON San Joaquin Experimental Range (SJER). Site Description - Located at The San Joaquin Experimental Range, in the western foothills of the Sierra Nevada, this 18.2 kilometer terrestrial field site is a mix of open woodlands, shrubs and grasslands with low density cattle grazing. SJER is an ecosystem research experimental area. It was originally conceived as a cooperative interdisciplinary research center to identify cost-effect methods of commercial livestock production in the annual grass-oak pine woodlands, while maintaining the integrity of the ecosystem. More recently, research objectives have expanded and diversified to include research projects making contributions to our knowledge of the patterns and processes working in this ecosystem.
This is the AmeriFlux version of the carbon flux data for the site US-xTA NEON Talladega National Forest (TALL). Site Description - The TALL terrestrial field site covers 5300 hectares within the larger Oakmulgee District of the Talladega National Forest (475,000 hectares) in west-central Alabama. TALL is located within the Gulf Coastal Plain which is the dominant physiographic province (52%) of NEON's Domain 8: Ozarks Complex. It is also where the upper coastal plain gives rise to the Appalachian foothills. The lands of this region are rich a mosaic of forest types and habitats. Steep ridges to rolling hills fading to hardwood bottoms make up the diversity of forest conditions found in Oakmulgee. While known for its longleaf forests, over 40% of Oakmulgee is covered with a mixture of hardwoods and wetlands.
This is the AmeriFlux version of the carbon flux data for the site MX-EMg El Mogor. Site Description - The vegetation is Mediterranean-climate closed shrubland on sandy soils. Eddy flux measurements began in 2008, 20 years after the last wildfire. The site has been grazed lightly and sporadically.
