4. Correlation of Wind Flow and Timber Production P = 1/2d x A x V 3 Upwind trees can reduce wind velocity by causing turbulence Clearing/vegetation management maintains power production efficiency

5. Effect of Wind Power Harvesting on Timber Management Wind Rose Identifies energy to be harvested Wind Box Identifies the area to be cleared to facilitate energy production

6. Wind Box Estimate Each Turbine Site: Construction area 2 acres – already cleared for turbine installation Wind flow clearing area 0 acres  12.5 acres (depending on topography)
