A few months ago I wrote an article regarding the eastern hemlocks and how they're being threatened by a tiny insect called the hemlock woolly adelgid. More than 95% of the hemlocks in the Smokies already have adelgids, which, if left untreated, will die in just a couple of years.
Yesterday, I discovered a series of videos produced by the Great Smoky Mountains Association which they've put together to explain what the adelgid problem is and what's being done to save the trees.
The films are interesting in that they show what the biologists are doing to treat the trees in order to fight the insect.
Although there are three films in this series, there is less than 8 minutes of total film time (I'm not sure why they just didn't make one film, oh well).
