Reestablishing
Pastures and Hay Meadows - Forage
stand condition after burning
Fire has always
played a major role in forest and rangleland history. The effects
of fire on heavily forested areas may last for centuries. On rangelands
and pasture, the effect of fire may range from being beneficial
to being equivalent to resulting in severe overgrazing.

Burning a pasture
or hay field can have several effects. Early in the season, cheatgrass
can be controlled in fencerows, roadways or pastures with minimal
effect to a pasture. Shallow-rooted forages such as some of the
fescue species may survive burning, but must be monitored to insure
that overgrazing of the re- growth does not diminish pasture health.
Burning in the fall is more critical. Some perennial plants may
be killed outright, or predisposed to winterkill. Fire destroys
the plant litter, which results in the loss of organic matter and
sets the soil up for erosion problems, depending on slope and winter
precipitation. Further, burning can reduce stand productivity and
competition, resulting in weed encroachment. In short, a recent
one-time burning of a hay meadow or pasture may have resulted in
a range of consequences - from complete loss of desirable
forage vegetation all the way through a beneficial effect. Successful
restoration requires prompt action with appropriate tools.
