Following ARS concurrence, these ten sites were announced as the initial LTAR network.
The LTAR Research Committee, which is comprised of a representative from each LTAR site and chaired by an ARS National Program Leader, has drafted a shared research strategy as a roadmap to guide network development.
In September 2012, the LTAR network held its first annual meeting in Estes Park, Colo.
While the ten initial LTAR sites cover significant portions of the hydrologic, eco-climatologic, and agronomic diversity of the United States, there are still gaps to fill, such as the Lower Mississippi River basin, the Lower Chesapeake Bay, and key agricultural states like California, Florida, and Idaho.
Information from the LTAR network can also contribute to the development of agricultural production systems that maximize energy conservation and reduce greenhouse gases.
ARS scientists working within the LTAR network interact and collaborate with researchers from other national ecological research networks, including the National Science Foundation's Long-Term Ecological Research and Critical Zone Observatory networks; the National Ecological Observatory Network (NEON), now being developed by the National Science Foundation and NEON, Inc.
This realization is the foundation for our work in the LTAR network.
Sidewall exfiltration of effluent above the ponded biomat was not included in the prediction; thus, the LTAR were likely to be conservative.
These models have provided a useful basis for predicting biomat development and hence LTAR of SAS.
