<DIV STYLE="text-align:Left;font-size:12pt"><DIV><P><SPAN>This dataset shows the results of an assessment of trends for 500 terrestrial ecosystems in the U.S.. The assessment considered trends in different indicators to gauge the probability of ecosystem collapse using four criteria : 1) ecosystem extent, 2) the degree to which ecosystem distribution is restricted, 3) the extent and relative severity of environmental degradation, and 4) the extent and relative severity of disruption of biotic processes. Ecosystems are categorized according to the IUCN framework for risk assessment based on their level of risk and probability of range-wide collapse; (e.g., collapsed (CO), critically endangered (CR), endangered (EN), vulnerable (VU), near threatened (NT), least concern (LC), data deficient (DD), or not evaluated (NE).
