Detailed explanation-1: -Over-abundant deer populations also reduce the diversity of plants and other wildlife species found in the forest. High levels of browsing by deer can completely remove the shrub and tree seedling layers in a forest. Many native wildflower species are also preferred deer foods.
Detailed explanation-2: -Deer populations increase through births or when new animals move into the area (immigration). Deer populations decrease through deaths or when animals leave the area or disperse (emigration).
Detailed explanation-3: -Deer populations have the potential to grow at fast rates, but this growth is limited by deaths, which occur for a variety of reasons. Studies have shown that the annual mortality of the fawn segment of the population can be as high as 40 percent.
