Abstract:

This 2012 revision to NatureServe conservation status builds on the 2009 version developed by the Element Ranking Work Group. There were five main issues that NatureServe felt needed review: Population size/scales, Trends, Area of Occupancy for ecosystems, Threats, and the Biotics Upgrade to incorporate the revised rank methods. The first four are discussed within, along with element occurrence issues. Guidelines and definitions are included in this explanatory report, as well as comparisons of NatureServe statuses with IUCN Regional Red List and COSEWIC statuses.
