Castanea dentata

chestnut snag
This snag, or dead tree, has been standing since it was killed by the chestnut blight that moved through Pennsylvania by the early 1920’s.
Wildlife, such as turkey, bear, deer and squirrels depended on this tree for food. It was a very fast growing tree. The largest American chestnut tree ever recorded before felling was 54 feet in circumference (approximately 17 feet in diameter).

HAWT

Large three-bladed horizontal-axis wind turbines (HAWT) with the blades upwind of the tower produce the overwhelming majority of wind power in the world today. These turbines have the main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind.
In 2009, for every bird killed by a wind turbine in the US, nearly 500,000 were killed by cats and another 500,000 by buildings.–Wikipedia
