Management of White-tailed Deer in Virginia
There is
considerable interest in the aesthetic, economic, and
educational values of white-tailed deer, as well as the
recreational opportunities they provide. With proper management
of both habitat and population, our deer herd will continue to
thrive.
While
white-tails are adaptable to a wide variety of conditions, good
quality food, water, and cover are essential. Forested lands
usually provide good habitat except where development,
large-scale agriculture, and poor forest management practices
have limited cover and food production. Timber harvests can
improve habitat quality for deer, if used to create an
interspersion of brushland, woodland, and openings.
Deer have a
varied diet and will eat practically anything green when
necessary but certainly display preferences that seem to be
based on nutritional quality. Forests should be manipulated to
maintain good quantities of grasses, soft-stemmed plants,
fruits, mushrooms, and acorn-producing oaks. Generally, 50% of
large forested tracts should be made up of mast-bearing oaks.
Woodlands
should be thinned to open the overstory and encourage desirable
understory vegetation. Thinnings should achieve a basal area
density of 50 to 60 square feet per acre. Openings in a forested
area encourage the production of preferred food plants and may
compensate for yearly and seasonal fluctuations in food
supplies, like acorns. Natural openings in forests should be
maintained. Openings of one to three acres in size should be
created, and be strategically located throughout an area to
provide diversity and edge.
- Allow
some openings to grow up in native vegetation, maintained by
annual mowing.
- Plant
other openings in annual crops such as corn, cowpeas, grain
sorghums, or winter wheat.
Prior to
planting openings for wildlife, contact a wildlife biologist for
specific recommendations.
Cover is
necessary for escape, breeding, rearing of young, and rest.
Brushy areas, cane thickets, old house sites, and small pockets
of dense, volunteer pines provide excellent cover and should be
protected from damage during forest management operations. When
larger tracts (greater than 20 acres) are clearcut, streamside
management zones and connecting corridors should be maintained.
Useable cover is not always obvious, so contact a wildlife
biologist for specific recommendations while planning forest
management operations.
Where food is
adequate and deer are generally healthy, a regulated harvest
will help maintain that condition and prevent over-use of
habitat. Keeping deer in balance with available habitat is not
difficult, but a specific recommendation, based on accurate
records, is essential. The Deer Management Assistant Program (DMAP)
is a program designed to use records of sex, date, antler
development, and productivity to create a harvest scheme that
will meet your deer management objectives. For further
information and a site-specific recommendation, contact your
district DGIF wildlife biologist. |
