Cottage Q&A: Deer browsing in winter?

Is that distinct line in the trees you can see as you look around the shoreline of a lake caused by deer browsing? It’s really pronounced on our lake. I’ve heard it’s from the deer browsing in winter as they stand on the ice. Is that true?—Name Withheld, Beaver Lake, Ont.

Sure is. “If you see a near-perfectly straight line, that’s likely wildlife chew,” says Matt Logan, an arborist with Logan Tree Experts in Lakefield, Ont. “It usually looks like someone has come along with a hedge trimmer.”

Depending on the height of the horizontal line, it could actually be a number of ungulate species, says Ashley Autenrieth, a deer biologist with Michigan’s Department of Natural Resources. So, without more details, we can’t rule out, for example, elk or moose. “The browse line is essentially the line to which ungulates browse an area as high as they can reach.” 

Happily, most trees survive this kind of animal assault. “The trees will be fine,” says Logan. “It’s a natural process.”

But the deer? Unfortunately, if the population is large enough, “ungulates can be their own worst enemies, and eat themselves out of house and home,” says Autenrieth. “This is where the balance between predators and prey can be a key factor. The landscape needs predators to balance out prey, so that areas can regenerate and produce enough food and resources for all wildlife.”
