Ruffed Grouse Habitat - Always Changing

Ruffed grouse coverts have a special place in my heart. Ever since I first got hooked on hunting ruffed grouse something like 35 years ago I’ve built a mental collection of patches of woodland that shelter and nurture ruffed grouse and other wildlife. It hasn’t always been easy, as I had to come up with a new collection of coverts when my last job transfer brought us to Montana 22 seasons ago, and I had to say goodbye to old haunts in North Dakota.

The term, ‘covert,’ incidentally, the word used to describe ruffed grouse hangouts, is defined in my dictionary as a hiding place, or a thicket affording cover for game. The emphasis is on the first syllable, to distinguish it from covert (with emphasis on second syllable), as in a spy mission.

It’s another example of why our English language is confusing. Adding to the confusion is that covert can be pronounced with a silent ‘t.’ In fact; some writers have come to even drop that ‘t’ and just use the word, ‘cover,’ to describe ruffed grouse hangouts.

My collection of grouse coverts is more than scattered aspen-covered hillsides and creek bottoms. They’re the repository of memories from many hunts over the years and the Labrador retrievers who shared those hunts and, of course, the ruffed grouse, that wonderful game bird that stubbornly ekes out a hardscrabble living in the thickets.

Grouse coverts are dynamic places in constant change. Ruffed grouse thrive in forested areas with a variety of habitat, with a mixture of different age classes of aspens and brushy cover, along with access to denser forest for refuge from severe weather or predators. As the forest matures, conifers take over, shading out aspens and ground cover. Eventually, as far as ruffed grouse are concerned, the forest becomes a virtual desert.

One grouse area and one of the more productive, as far as numbers of grouse flushed—which does not always translate to shots fired or birds on the dinner table, was approaching that climax stage, though with another wrinkle: mountain pine beetle. The last couple years I often thought that the area needed a controlled burn or a logging operation to clear out dead and dying pine trees and to revitalize the habitat.

On a snowy November day I made my annual visit to the covert and saw that a well-publicized logging operation on the Mt. Haggin Wildlife Management Area was, in fact, on this grouse covert. It was quite a change; with formerly dense stands of trees now pretty much gone and with aspen trees the main survivor.

One question in my mind was answered when Flicka, my Labrador retriever, put up a grouse from a hillside that had not been logged. I managed to scratch the bird down on my second shot. Flicka was retrieving the bird when another grouse flushed from in front of her. Flicka forgot about the grouse in her mouth to chase after the bird in the air. We later flushed another grouse from aspens in the logged-over area. In spite of a couple months of putting up with logging operations, the grouse are still in residence.

I subscribe to a newsletter, “Grouse Tales – the Official Newsletter of the Loyal Order of Dedicated Grouse Hunters.” In a recent issue one person wrote of trying to find a certain clear-cut area in Michigan and asking a Forest Service employee for directions. The Forest Service person pointed out it wasn’t a clear-cut; it was an aspen regeneration area. As they continued the conversation, every time the person said clear-cut, the forester corrected him, “It’s aspen regeneration.”

In fact, studies have shown that ruffed grouse love those old clear-cut—excuse me, aspen regeneration areas, especially in the 5 – 15 year period following the logging operation. It’ll be interesting to see how this area recovers in coming seasons and whether the grouse have a population boom.

For now, the covert is blanketed in snow, and after the grouse season closes next week, the only predators the grouse need worry about will be those with talons or jaws.
