If you are interested in conservation and have an interest in insects, in their own right, or odonates in particular (i.e. dragonflies and damselflies), you are likely to find this 1 hour 23 minute YouTube video to be very informative indeed.
The video is of a webinar developed for Natural Resource Conservation Biologists that covers dragonfly life history, ecological roles, conservation status, habitat needs, and their intersection with the NRCS Wetland Reserve Program.
A separate, very useful website for anyone interested in odonates is: www.odonatacentral.org
