In whatever area a deer lives, it will more likely thrive if the foods it needs are well spread out over the entire area. Recent studies have shown that as deer change the plant species composition of a given area, they alter microclimates, and affect light availability and spatial patterning on the woodland floor. The basic prescription requires a reduced deer population for an extended period of time, coupled with replanting, reseeding, and control of non-native invasive plants.

Why is there a shortage of tomatoes in the UK? Like all animals, deer have certain living requirements essential to their existence; food for nourishment and cover for protection are the two most important. Too many deer in a given area results in overgrazing and the eventual loss of brush and shrubs in forested areas. Some experts refer to this as axe, as cutting is needed to manage and control brush. To this end, I focus on intraspecific skeletal variation, with an emphasis on tail length, in the deer mouse, Peromyscus maniculatus.
