RANGE MANAGERS MUST PLAN BURNS
CRP grasses build excessive litter making travel difficult for
young wildlife
PRATT - Kansans who own or manage CRP grasslands and want to maximize
that land's value for wildlife have an important decision to make in
late winter or early spring: Is a controlled burning in order this
year? Periodic burning is a necessary component of CRP management.
Without it, grassland's value to small game is diminished.
"The native grasses that comprise our CRP plantings have a tendency to
build up excessive ground litter over time," says Randy Rodgers,
upland bird research biologist for the Kansas Department of Wildlife
and Parks (KDWP). "When too much litter is present on the ground, the
cover provided by these grasses becomes almost unusable for all but
our largest species of wildlife. Young wildlife, such as pheasant and
quail chicks, find these dense mats of grass litter virtually
impassable. Chicks hatched in dense, unmanaged CRP grasslands find it
impossible to follow the hen from the nest. They quickly become lost
or exhausted and soon die."
The recommended solution to this problem is fire. An occasional
controlled burn can open up a grass stand, creating abundant pathways
for wildlife. The grasses also become healthier.
Fearing fire, some managers hesitate to burn. CRP guidelines remove
much of the danger. Strip disking is a provision that will allow a
cooperator to disc strategically-located strips, allowing a much safer
and more manageable burn. Those managers who don't have heavy farm
equipment will probably have to mow the strips that will be fire
barriers before disking them. Mowing, followed by disking, greatly
reduces the amount of combustible material at the site of the fire
break.
Managers should contact their local Farm Service Agency (FSA) for help
and to amend contracts to allow strip disking. To be most productive
for wildlife, this tillage should be performed in late February or
early March, and the burn should be performed during the last week of
March or the first week of April. Rural fire departments must also be
notified of the planned burn day. A few Kansas counties require more
advanced notice and a burning permit.
By setting a backfire inside the disked firebreak on the downwind side
of the field, a wide blackened area is created. Once that is done,
additional fire can be set inside the firebreak around the perimeter
of the field, eventually reaching the upwind side where a head fire
can be set to complete the burn.
To create greater diversity, a fireguard can be disked around half the
field, that half burned, and the other half left unburned. The second
half can be burned the next year. In this way some unburned and some
recently burned habitat is always present, offering both nesting and
brood-rearing needs in the same field.
Cooperators who wish to go the extra mile should consider interseeding
forbs into the burned acres. Forbs such as grazer alfalfa, Maximilian
sunflower, bundle flower, partridge pea (in sandy soils), purple
prairie clover, and purple coneflower serve as food for insects. For
information on forb seeding and seed sources, contact your district
Wildlife and Parks biologist.
