Quick Answer
Fescue growth patterns affect deer by altering the quality and quantity of available forage, particularly during times of drought or high deer pressure. Tall fescue tends to produce more biomass than other types, but also contains toxic compounds that can impact deer health. This can lead to stunted growth and reduced body condition in deer.
Understanding Fescue Growth Patterns
Deer managers and hunters in Kentucky’s big buck country need to understand the growth patterns of fescue to make informed decisions about habitat management. Research has shown that tall fescue can produce up to 4-6 tons of dry matter per acre per year, making it a valuable food source for deer. However, this same grass also contains a toxin called ergot alkaloid, which can cause reproductive issues and reduced body condition in deer.
Creating a Balanced Habitat
To create a balanced habitat that benefits deer, it’s essential to incorporate other forage species that are less toxic and more palatable. This can include grasses like switchgrass, big bluestem, and Indian grass, as well as legumes like clover and beans. By incorporating these species into the landscape, deer managers can create a more diverse and resilient habitat that supports healthy deer populations.
Managing Fescue for Deer
For those who want to manage their fescue for deer, it’s essential to consider the timing and frequency of grazing. Research has shown that deer can be managed on fescue by allowing them to graze for 30-60 days during the early growth stage, followed by a 60-90 day rest period. This allows the fescue to recover and regrow, producing new biomass that is less toxic and more palatable to deer. By managing fescue in this way, deer managers can create a sustainable and deer-friendly habitat that supports healthy populations of Kentucky’s big bucks.
