How can something so small cause so much destruction?

It was hard to see at first, but once we spotted it, we started seeing it everywhere. 

The Hemlock Woolly Adelgid (HWA) is tiny. These white, fuzzy spots are its egg sacs.

Accidentally introduced to North America from Japan, HWA was discovered in the eastern US in the 1950s. As of 2015, 90% of the geographic range of eastern hemlock in North America has been impacted by HWA.

The DCNR and the Forest Service is fighting the HWA outbreak in Cook Forest State Park in several ways, which will be detailed in our Cathedral film. It's a tough, long fight, but one that must be fought. We cannot lose the ancient hemlocks of Cook Forest. We would all be the poorer for it.
