Hemlock Woolly Adelgids are devastating the eastern hemlocks. What are we doing to help save them? It seems the answer lies in a few different approaches - predator introductions, saving the genes, regrowing the species and using some chemical applications.
I'm sure you've probably heard of at least a few invasive species. Maybe you've heard of the Cane Toad. It's one of the classic introductions of invasive species gone wrong. It was introduced to eat pests in cane fields and then turned into a plague of epic proportions in Northern Australia.
This video was taken at the Carpenters Elementary School Environmental Science Day on March 10, 2017. Carpenters Elementary is part of the Blount County School system and is located in Maryville, TN.
This new video by Untamed Science features the scientists and research at Coweeta Hydrologic Laboratory.
This video was shot on the Nantahala Ranger District of the Nantahala National Forest in western NC. Forest Service Research Forester, Stacy Clark, describes a study that is comparing hybrid American chestnuts bred for blight resistance against pure American chestnut (not blight resistant) and pure Chinese chestnut (blight resistant). For each seedling type (hybrid, American, Chinese), the study is also comparing the effect of container grown seedlings using a patented container method (RPM ®) versus seedlings grown as bareroot nursery seedlings
Katherine Elliott discusses preparatory measures being taken at Coweeta in the face of the Rock Mountain Fire.
Research Ecologist Chris Oishi discusses techniques for measuring sap flux, and introduces a new processing program that can help interpret and normalize this data.
Smokey's message is clear now - don't start a forest fire. He makes no judgement about whether or not the fire itself is good or bad. That's because we know how important fire is for the ecosystem.
The eastern United States' mightiest tree, the oak, is in decline, possibly due to over-harvesting or climate change. Whatever the cause, scientists are trying to find ways to reverse this decline. Watch U.S. Forest Service researcher Tara Keyser and others use fire to give young oaks room to grow in the North Carolina mountains.
A Plan for the North American Bat Monitoring Program (NABat) provides detailed guidelines for participating in NABat, an international multiagency program created to provide the data needed to make effective decisions about bat populations across the North American continent.
Susan Loeb, SRS research ecologist, served as lead author on the new publication, which represents the first step in establishing the NABat monitoring program for bats in North America.
