Decline in Hunters Affects USA Deer Management

Each year, American deer hunters are aging out of the sport. Meanwhile new hunters are not being recruited to replace them. 

Due to the decline in hunters, deer management strategies will need to change to manage populations of whitetails in many states.

That is the conclusion of Penn State’s Duane Diefenbach, one of the leading white-tailed deer researchers in the USA. He suggests that demographic trends of big-game hunters will dictate that wildlife agencies consider modified, or completely new, regulations to manage white-tailed deer populations.

“Recreational deer hunting is the primary tool that’s available to state wildlife agencies to manage the resource, but in the next 10 years we’re going to see a steep decline in the number of hunters,” said the adjunct professor of wildlife ecology in the College of Agricultural Sciences. “A few states still have large numbers of hunters, but this is coming at all the state agencies very quickly. In the next 10 to 15 years, there’s going to have to be changes. The question is, what alternative tools are available to meet this deer-management challenge?”

The North American Model for Wildlife Conservation, which treats wildlife as a public resource not owned by individual landowners, has relied on revenues from the sales of hunting licenses largely to pay for wildlife conservation for more than a century. With fewer hunters, the challenge will be to find new tools to achieve management goals, according to Diefenbach.

Diefenbach outlined concerns about the effects of hunter demographic trends in a chapter of the recently published book, “Harvest of Fish and Wildlife: New Paradigms for Sustainable Management.” 

Diefenbach co-wrote the chapter, “The Future of Managing Ungulate Species: White-tailed Deer as a Case Study,” with Matthew Knox and Christopher Rosenberry, deer biologists with the Virginia Department of Wildlife Resources and the Pennsylvania Game Commission, respectively.

Research by the trio suggests that the coming decline in hunters will have major impacts on deer populations. Part of the decline is associated with changes in demographics.

“Compared to the general population, demographics and residency of big game hunters have changed little over the past 30 years,” he writes, adding that National Hunting, Fishing, and Wildlife-Associated Recreation surveys of 1991 and 2016 show big game hunters have remained more than 90% male and 97% white; whereas the U.S. population is 48% male and non-whites have increased from 15% to 22% of the population.

In the general U.S. population, there has been an increasingly older age structure, Diefenbach noted. In 1991, 41% of the U.S. population was more 45 years old, which had increased to 52% by 2016. However, hunters more than 45 years old increased from 28% to 60% during the same time period.

In some states, wildlife managers are applying new strategies to control deer populations. Allowing hunters to take multiple deer is one. In Virginia, managers there have been effective at increasing the harvest of antlerless deer by implementing a unique “earn a buck” program.

To participate in the program, once a hunter in Virginia harvests an antlered buck, he or she must then harvest at least one antlerless deer before they can harvest a second antlered buck.

Diefenbach has conducted more than a dozen peer-reviewed studies over the last 20-plus years, carefully monitoring hundreds of deer that were captured and fitted with radio or GPS collars.

Leader of Penn State’s Pennsylvania Cooperative Fish and Wildlife Research Unit, Diefenbach has overseen two fawn mortality studies (the latter with a predator-identification component), a fawn stress study, studies on bucks that looked at the effects of antler-point restrictions and dispersal, research on female deer harvest rates and survival, and female deer dispersal.

Diefenbach worked for the Pennsylvania Game Commission for seven years before arriving at Penn State. He also has done projects that looked at developing population estimators to assess deer abundance, estimating hunter-harvest rates and assessing the impacts of selective browsing on forests.

Wyoming Mule Deer Initiative Projects

Mule Deer
In November, the Wyoming Game and Fish Commission (WGFC) voted to approve $560,000 for ten projects to support mule deer populations across Wyoming.

Developed through the Statewide Mule Deer Initiative (MDI), the new projects will focus on improving to mule deer habitat and migration paths.

The projects will build upon MDI efforts that have been ongoing for over a decade.

The projects slated for the coming year are expected to benefit nine herds of mule deer and improve 1.2 million acres of habitat.

In Wyoming, Mule deer are an iconic species. They are found in the high plains, great basin desert, the alpine mountains, and everywhere in between.

A statewide Mule Deer Initiative written by the Wyoming Game and Fish Department was adopted by the Wyoming Game and Fish Commission in July 2007 and updated in July 2015.

The Mule Deer Initiative outlines factors contributing to declining mule deer populations and identifies strategies to, at minimum, sustain current deer numbers.

Wetland, Woodland, Wildland Guide to Natural Communities of Vermont

A completely updated second edition of Wetland, Woodland, Wildland: A guide to the natural communities of Vermont will be available in late 2019. 

The land guide is well-known to anyone curious about Vermont’s forests, wetlands, mountaintops, and shores.

Co-authored by Elizabeth Thompson of the Vermont Land Trust, and Eric Sorenson and Robert Zaino of the Vermont Fish and Wildlife Department, the new second edition incorporates recent scientific research about the state’s natural communities and includes descriptions of seventeen newly recognized natural community types.

The new guide includes photographs, line drawings, and user-friendly writing, related to natural habitats of Vermont. The updates will be useful to amateur naturalists and professional scientists.

“Natural communities help us understand nature. When people can see patterns across the landscape, they have a better appreciation of nature and a heightened sense of responsibility to protect it,” says co-author Elizabeth Thompson.

Natural communities are also important for the conservation of plants, animals, and habitats in Vermont.

The book is published by the Vermont Fish and Wildlife Department, The Nature Conservancy, and the Vermont Land Trust, and it is distributed by Chelsea Green Publishing.

It is currently available for pre-order online (https://vtfishandwildlife.com/wetland-woodland-wildland) and is expected to be for sale in local bookstores by November 15.
