Recommendations for haying in a wildlife-friendly manner

By FWP Region 6 Upland Game Bird Specialist Ken Plourde

Haying season is fast approaching, along with critical nesting and brood-rearing periods for Montana game birds like pheasants, grouse, Hungarian partridge and waterfowl. Many of these birds try to nest or raise their young in hay fields, which can cause big problems for them when haying equipment comes around.

Each year, many nests are destroyed, and hens, chicks and deer fawns are killed by haying equipment. However, just a few small conservation measures during the haying operation can reduce those losses by 60 percent or more. Landowners who are haying this season are asked to consider adopting some of the following practices to give game birds and other wildlife a better chance of surviving:

If possible, wait to hay or mow until after July 15, or better yet Aug. 1. By this time most nests are hatched and chicks are big enough to run and escape mowing equipment.

Raise the mower deck to 4 inches to 6 inches off the ground. This reduces the chance any nests and eggs will be destroyed when the mowing implement passes over.

Hay only during daylight hours.

Use a flushing bar. These simple devices give hens a chance to flush from nests far enough away from the mower that they will not be caught.

Drive slower in areas where wildlife are more common or have been observed in the past, like near brushy areas or wetlands.

Hay the field in a pattern that allows wildlife to escape the field safely. A common practice is to circle the outer edges of the field first then work the way toward the center.This “death spiral” pushes wildlife toward the center of the field where they are eventually run over, or forces them to cross open space and risk predation to reach safe cover.

Instead, producers should consider beginning at one end of the field and work back and forth across, pushing wildlife toward an area of safe cover. Another pattern is to begin in the center of the field and work outward.

Leave borders around the field of 20-60 feet wide. Research shows that most pheasant hens nest within 50 feet of the field edge. Leaving a little habitat around the edges can go a long way toward reducing wildlife mortality.

By trying just a few of these haying practices, landowners can greatly increase the chances that wildlife will survive haying season, and may lead to more robust populations on their property year-round. If producers would like more information or recommendations about small ways that they can help game birds and other wildlife on their agricultural operation, they can call the nearest Montana Fish, Wildlife and Parks wildlife biologist.
