Habitat
Management for Rabbits in Virginia
The cottontail
rabbit is one of Virginia's most popular game animals. The
cottontail rabbit is legendary for its reproductive
capabilities. Cottontails also have a very high annual mortality
which often approaches 85% due to predation, weather, habitat
destruction, diseases, and parasites.
One of the
easiest, quickest, and least expensive ways to enhance "rabbitat"
is to create brush piles. These should be located near ungrazed
pastures, fence corners, or along weedy fence rows.
Some
modifications of current farming practices will benefit
cottontails as well. Fall plowing should be avoided whenever
possible. Fall plowing destroys all cover. Grain fields should
be combined "high", leaving enough stubble to provide some cover
and emergency winter food.
Fence rows
should be allowed to grow up into briars and weeds to provide
safe travel corridors. Hedgerows should be planted to break up
large fields. Field borders, or buffers, at least 30 feet wide
should be left around all fields to provide edge. Often, edge
habitat is the primary component of rabbit habitat that is
lacking on a well kept farm. You might consider some of the
following shrubs and trees for your field border and hedgerow
plantings: sargent crabapple, indigobush, silky dogwood,
serviceberry, American plum, arrowwood or blackhaw viburnum,
white pine, or cedar.
Bush hogging,
if absolutely necessary, should be delayed until after August 1.
The bush hog should be set as high as it will go. This will help
retard woody growth, destroy the least amount of nests, and
still leave some cover. Remember, the bush hog is not a wildlife
management tool.
When making
hay, keep in mind the buffer as mentioned above. Rabbits will
usually nest along the edges of fields in the denser cover.
Instead of mowing an entire field, mow 30-40 foot strips and
rotate the strips every 3 or 4 years.
Livestock
will often destroy rabbit habitat by eliminating ground cover.
Fence off some corners or other "odd" areas, such as gullies,
abandoned farmsteads, streams, or dams to protect them from
grazing.
Food plots
are usually not necessary for rabbits. In general, if you
provide cover, rabbits will find something to eat. However, if a
planting is desired, a mixture of 5 lb/acre of ladino clover (or
another legume) and 10 lb/acre of orchard grass is best.
Dense
woodlots can be transformed into suitable rabbit habitat by
opening up or thinning the stand so sunlight can reach the
forest floor in order to stimulate growth of understory
vegetation. Debris from thinning can be used for firewood and to
create brush piles. Many of the fallen tree tops can be left "as
is" and should not be piled. Cottontails will nibble on the bark
during the winter. Several small openings about one acre in size
will produce more rabbits than one large one.
Pines and
cedars provide particularly good winter cover for cottontails.
In areas where coniferous cover is absent, planting clumps of
pines and cedars might be worthwhile. Top the cedars when they
get to be about five years old. Cedars will start loosing their
lower limbs as they get older and will no longer provide thermal
cover for rabbits. Discarded Christmas trees can also provide
excellent shelter for rabbits. Pile yours and your neighbors' up
in the back yard or near areas where rabbits will use them.
Habitat
management for rabbits is easier than for most other game
animals. With little labor and virtually no cost, you can
improve the "rabbitat" on your land. Remember that "planned
neglect" is often as good as active management. If you need
further assistance, contact a wildlife biologist from the
Virginia Department of Game and Inland Fisheries for free
technical assistance. |
