Brainerd – Minnesota deer hunters know last fall's acorn crop was nearly a complete failure, forcing whitetails to shift to other fall food sources.
Lacking acorns as a nutritional option, deer moved from oak ridges and flats to other locations to fill their stomachs. From waste corn and soybeans in farm country, to lowlands containing red-oiserdogwood in the northern forested areas of the state, deer found resources to put on a layer of fat in hopes of getting through the winter.
Food plots planted for deer are common nowadays. Many landowners, too, maintain their forested lands by cutting selected trees to open up the canopy because that allows more sunlight to reach the ground. The practice encourages new-growth vegetation that deer and other wildlife feed on and use for cover.
Food sources and bedding cover available to deer in natural meadows and forest openings are often overlooked by whitetail fanatics. Sunlight there can help the development of nutritious forbs such as goldenrod, and new-growth shrubs and trees such as hazel, dogwood, sumac, raspberry, blackberry, oak, maple and other species.
For landowners who don't have the equipment, time or resources to plant food plots, maintaining forest openings is a cheaper and less time-consuming endeavor.
With a little work you can make openings you already might have even more attractive to deer. How much work goes into creating or maintaining natural openings depends a lot on soil type and elevation.
Deer are browsers, not grazers. Yes, whitetails do feed on grass, especially that in the early growing stages. However, many forest openings are overrun by various species of grass that overwhelm and discourage the growth of forbs and young trees.
My property near Brainerd is primarily lowland. An invasive plant called reed canary grass quickly takes over any areas on my land exposed to the sun. Reed canary is a perennial grass that can grow as high as 6 feet. It out-competes the native species on my land if left unchecked, and forms a pure stand allowing nothing else to grow. Whitetails do not eat reed canary grass. Yes, deer do use reed canary as bedding cover, but a wet snowfall will easily flatten the grass. Thus, it is mostly useless to deer as winter cover.
