The booming deer population in the northern United States is bad for the animal's beloved hemlocks, a new study finds. During Michigan winters, white-tailed deer converge on stands of young hemlocks for protection from winter chill and predators. The same deer return every year to their favorite clumps of the bushy evergreens, called deeryards. The high concentration of deer in a small space saturates the soils with nitrogen from pee, according to a study published online in the journal Ecology. While deer pee can be a valuable source of nitrogen, a rare and necessary nutrient for plants, some deeryards are now too rich for the hemlocks to grow.
