Views of Declining Hemlocks from On High

The views from the Eddy Flux towers in a hemlock stand at Harvard Forest may be providing a good last look at the hemlock forest while it is reasonably intact. According to Harvard Forest director, David Foster, " the foliage is beginning to take on that gray cast of moribundity, light levels are increasing in the understory, and trees are beginning to die as their crowns thin.  But, the forest is still striking as is the view from the top of the tower, though the leaders of tallest trees are showing decline."
