 Loss of natural habitat can occur through introduction of forest monoculture or by even aged timber management, which are also destructive of biodiversity and wildlife abundance.For example, many wildlife species such as the wild turkey depend upon variegation of tree ages and sizes for its optimal sub-canopy flight; forests that have been managed for even aged composition fail to achieve abundance values of the wild turkey and many other organisms.Large natural forest areas are also important for maintaining ecological processes and supplying ecosystem services like water and air purification, nutrient cycling, carbon sequestration, erosion and flood control.
