Paragraph 2: Nearly any kind of plant of the forest understory can be part of a deer's
diet. Where the forest inhibits the growth of grass and other meadow plants,
the black-tailed deer browses on huckleberry, salad, dogwood, and almost
any other shrub or herb. But this is fair-weather feeding.What keeps the
black-tailed deer alive in the harsher seasons of plant decay and dormancy?
One compensation for not hibernating is the built-in urge to migrate.Deer may
move from high-elevation browse areas in summer down to the lowland areas
in late fall. Even with snow on the ground,the high bushy understory is
exposed; also snow and wind bring down leafy branches of cedar, hemlock,
red alder, and other arboreal fodder.

2. It can be inferred from the discussion in paragraph 2 that winter conditions
○ Cause some deer to hibernate
○ Make food unavailable in the highlands for deer
○ Make it easier for deer to locate understory plants
○Prevent deer from migrating during the winter
