Georgia Envirothon

The Georgia Envirothon, offered in cooperation with the National Conservation Foundation (NCF) Envirothon, is a 501(c)3 non-profit organization established in 1995 to provide hands-on, science-based training in natural resources and ecology to middle and high school students in a challenging, fun, and competitive outdoor experience.

YHC – Hemlock Project

The Young Harris College (YHC) Hemlock Proiect is a volunteer effort of community members and students to help raise Sasajiscymnus tsugae, a tiny ladybird beetle that is one of the few natural predators of the HWA. The organization works in conjunction with the Forest Service and GFC to decide where to release the adult beetles.

Biology and Management of the Hemlock Woolly Adelgid in the Eastern U.S.

Hemlock trees in eastern forests are late successional tree species that provide shade for the forest understory. Globally, there are ten hemlock species, with populations located in Asia and eastern and western North America12. Eastern hemlock (Tsuga canadensis) and Carolina hemlock (Tsuga caroliniana) grow in the eastern U.S. These trees have great ecological and cultural value in forests. However, the invasive hemlock woolly adelgid (Adelges tsugae or HWA) is decimating hemlock populations throughout much of the trees’ native range, altering landscapes, and threatening these iconic tree species in both rural and urban areas.
