Burning Large Grasslands Burning reduces buildup of dead vegetation, adds nutrients to the soil, rejuvenates plant growth, and helps prevent the spread of woody vegetation. Hayfields that develop a thick layer of thatch are usually not used by nesting birds because they cannot effectively run on the ground to escape predators or forage for food. Although burning is not always feasible on small grasslands, when possible it can benefit grassland bird populations within one or two years following a burn. Recommendations Burning every two to six years provides the best habitat for birds nesting in small grasslands. If possible, provide adjacent unburned grassland habitat for nesting birds during the burn year.
Careful planning is necessary before burning.
Most grassland burns occur between mid-March and the end of April, after snow melt and before greening and bird nesting. The timing of the burn must also be done with consideration of relative humidity, wind conditions and direction, air temperature, and fuel conditions. Adjacent landowners should be notified prior to burning. Contact your local fire department for guidance and permits before burning a field.
