The species listed below are monitored by the NJDEP Natural Heritage Program. We are concerned about these species, especially for their own survival, but also for their importance as water quality indicators. While we are interested in all odes, we would certainly like to hear about any sightings of the species listed below. Please report any encounters through Odonata Central.
The State and Global rankings give a quick summary and overview of each species' status, stability and abundance. Click here for a definition of these rankings and to learn more about the ongoing efforts of the Natural Heritage Program. In the following table, we list the species that are currently ranked from S1 through S3 by the NHP. Clicking on the name of any ode will take you to the detailed page for that species.
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
explore their site but please, come back soon!
Following are the State element ranks used in tracking NJ odes
(and other organisms as well). Click

are also displayed in our database.

Conservancy (1982: Chapter 4, 4.1-1 through 184.108.40.206-3).
