The South Atlantic LCC is seeking technical assistance in the testing process for their newly chosen terrestrial natural resource indicators (https://www.fws.gov/science/catalog). For each ecosystem and the three indicators within each ecosystem, South Atlantic LCC staff and collaborators are seeking to answer the following: 1) How well does each indicator represent a variety of organisms and ecological attributes within the ecosystem and throughout a major portion of the LCC? What does it miss? 2) How well does combination of three indicators within each ecosystem represent a variety of organisms and ecological attributes within the ecosystem and throughout a major portion of the LCC? What do they miss? 3) How sensitive is the indicator to the biggest landscape scale threats in the LCC? Does it vary widely based on natural variations and disturbances that are not true threats? Data and GIS predictions of past, current, and future conditions of the South Atlantic LCC will be provided by the South Atlantic LCC staff.
