The NJDEP's Natural Heritage
Program classifies and tracks rare species of odonates in New
Jersey to help prioritize conservation efforts and NJOS strongly
supports their efforts. They use standardized state and global rankings that were
developed by the Nature Conservancy and NatureServe. See below for the full definition of the ranks that
are used in this site.
The NJDEP Natural Heritage Program maintains
its own web site with information on their on-going programs and data on many other animals and plants. Click

(and other organisms as well). Click

NJOS note: Definitions for element ranks are after The Nature
Conservancy (1982: Chapter 4, 4.1-1 through 18.104.22.168-3).
