Hemlock trees are among the largest and most dramatic conifers in the region.  They also play a vital role in cooling steams and providing habitat for many species.  Unfortunately they are under attack from a non-native insect called the Hemlock Woolly Adelgid.  Without successful intervention the Hemlock Woolly Adelgid is likely to kill most of the hemlock trees in southeastern Ohio.

Treatments are proving successful in regions where the Hemlock Woolly Adelgid has already infested the trees.  With your help the hemlock trees in Southeast Ohio can be treated to minimize tree loss.


The Hocking Hills Conservation Association (HHCA) was founded in 2013 with the purpose of providing funding for conservation, preservation and education projects to ensure the viability of natural resources owned by public and/or non-profit organizations operating according to section 501(c)(3) of the Internal Revenue Code.

HHCA is a collaboration of the Ohio Department of Natural Resources, Ohio Department of Agriculture, OSU Extension, Metro Parks, Hocking County Soil & Water Conservation, Hocking County Tree Commission and Hocking Hills Tourism Association, Camp Oty'Akwa and concerned citizens.


HHCA's priority project at this time is saving the hemlock trees in southeast Ohio, specifically, the Hocking Hills region.


Southeast Ohio's Hemlock Trees are in serious danger.
