What impacts deer movement patterns after heavy rain?

Impact on Habitat Selection

Heavy rain in Vermont’s big woods forces deer to reassess their habitat selection. Deer tend to migrate to areas with drier and more elevated terrain, often within 50-100 yards of their original locations. These areas may include ridges, hillsides, and the edges of wetlands. In these areas, deer can find food and shelter without being exposed to the saturated conditions that make them vulnerable to predators and harsh weather.

Changes in Daily Activity Patterns

Deer movement patterns in Vermont’s big woods also shift in response to heavy rain. Typically, deer are most active during the early morning and late evening hours. However, after heavy rain, deer tend to be more active during the late evening and early morning hours, often between 4-6 am and 6-8 pm. This adjustment likely occurs as deer attempt to avoid the saturated conditions and high visibility associated with daytime hours.

Effect on Food Availability and Selection

Heavy rain in Vermont’s big woods can impact the availability of food sources for deer. Deer tend to congregate near food sources, such as agricultural fields, orchards, and areas with high concentrations of mast-producing trees. In these areas, deer are more likely to be active and visible to hunters. Hunters can capitalize on this behavior by focusing on areas with abundant food sources and using tactics that take advantage of deer’s altered movement patterns.
