It’s no secret that mule deer face some critical challenges. Habitat loss, local weather change, stress from predators, persistent losing illness, and a bunch of different components are points for the West’s most iconic recreation animal.
Compared to elk and whitetails, mule deer are comparatively fragile, which is why the Mule Deer Foundation and similarly-minded conservation teams and people have devoted a lot time, power, and cash to serving to shield mule deer from the a number of threats they face in 2023.
One of probably the most important developments within the historical past of mule deer conservation was unveiled on the Western Hunting and Conservation Expo in early February, when the U.S. Forest Service and the Bureau of Land Management introduced a multi-year partnership with MDF that may funnel as much as $65 million into numerous conservation efforts over the following twenty years.
This is on the heels of greater than 300 MDF initiatives that tackled about 392,000 acres of habitat work (together with eradicating or modifying 171 miles of fencing) lately.

“This work with the Forest Service and BLM will allow us to greatly increase the scale and scope of MDF’s habitat projects,” says Mule Deer Foundation president and CEO Joel Pedersen.
Though this inflow of money is essential, it isn’t a silver bullet for mule deer conservation, notably on the subject of a few of the extra intractable issues confronting them.
Even describing the matrix of points precisely is a problem as a result of they overlap and affect one another, and are regionally particular as effectively. Issues with drought, suburban improvement, poaching, and illness are widespread issues that have an effect on many of the mule deer’s vary, however manifest in another way in Arizona, Colorado, and North Dakota.
That mentioned, listed below are the foremost issues dealing with mule deer and what’s being performed to mitigate them.
How Many Mule Deer Are There?
Before delving into the specifics, it’s price answering this primary query. One of the perfect sources of knowledge on mule deer and black-tailed deer is the Mule Deer Working Group, which consists of two dozen representatives from Western state, territorial, and provincial companies that handle these deer.
In their 2022 Range-Wide Status of Black-Tailed and Mule Deer, they estimate there are 3.4 million blacktail and mule deer stretching from Mexico to Alaska, with the most important populations present in California (475,000), Colorado (416,000), Utah (305,000), Montana (294,000), Wyoming (292,000), and Idaho (282,000).
While mule deer numbers aren’t the place wildlife managers want to see them, the general inhabitants is hanging in there.
“In most jurisdictions mule deer and blacktail populations are under their objective goals but—with a few exceptions—the populations are stable or increasing,” says Jim Heffelfinger, who chairs the Mule Deer Working Group.
Habitat
Habitat loss, fragmentation, and degradation is an overarching difficulty that encompasses lots of the issues mule deer face. Not surprisingly, this is the reason so many initiatives undertaken by the MDF and different critter teams concentrate on habitat.
Problem: Suburban and Exurban Development
Nothing hits mule deer more durable than encroachment on summer time and winter vary and the introduction of impediments like roads, fences, and housing that retains them from simply touring between the 2.
We may lump power improvement underneath this heading. Whether we’re speaking in regards to the set up of pure fuel wells in Wyoming or constructing a wind farm in New Mexico, power initiatives (“green” or in any other case) create issues for mule deer.
Solution: Fence Removal and Conversion
When it comes to creating it less complicated for mule deer emigrate, fence removing and rehabilitation is a high precedence.
“The easier you can make it for deer to get from where they are to where they need to go, the better,” says Ian Tator, terrestrial habitat supervisor with Wyoming Game and Fish Department.
A shining instance is the work that’s been performed to take away or rehabilitate greater than 691 miles of fencing within the Red Desert to Hoback hall, which is the world’s longest mule deer migration route.
To make fencing wildlife pleasant, the objective is to make the highest wire as little as doable (38 to 42 inches above the bottom) whereas making the underside wire as excessive as doable (16 inches off the bottom is okay; 18 is healthier). Such fences are nonetheless in a position to include livestock.
Solution: Reducing Collisions with Vehicles
In Wyoming, about 4 % of mule deer are killed by motorcar collisions yearly—a demise toll that dwarfs what predators kill, stories Andrew McKean, Outdoor Life’s looking and conservation editor. And that’s only a small slice of the better roadkill pie throughout the U.S. Each yr, roughly 2 million elk, deer, bear, rabbits, raccoons, and different critters meet their demise alongside America’s highways and nation roads.
The set up of “wildlife accommodation” fencing and the development of overpasses and underpasses that create a secure manner over or underneath highways for wildlife are a few of the steps being taken to cut back the demise toll.
A key part in McKean’s report states: As a part of final December’s federal infrastructure regulation, Congress devoted $350 million over 5 years to the Wildlife Crossings Pilot Program, which goals to incentivize states, municipalities, tribes, and NGOs to submit plans to cut back wildlife mortality within the spots with the most important roadkill issues. That’s along with the $350 billion the regulation appropriated for freeway initiatives over the following 5 years.
Solution: Conservation Easements
Conservation easements have been one of the vital efficient instruments for mule deer conservation, because it accomplishes the twin objectives of preserving the panorama intact whereas guaranteeing public entry. Typically, a rancher or different landowner will work with their state to buy rights to a good portion of their land, fairly than have the property damaged into smaller segments and offered off piecemeal.
This is a win-win in that it supplies landowners with much-needed money to maintain their operation going, whereas defending and conserving essential habitat—notably when the following technology within the household isn’t interested by ranching or farming.
In Montana, sadly, this program is underneath fireplace from Gov. Gianforte’s administration, which has reshaped the Montana Land Board with far-right politicians who appear hostile towards this system’s capability to safe easements in perpetuity.
Solution: Consulting with Developers
States within the intermountain West have historically been very pro-development, whether or not speaking about subdivisions or power exploration. That is unlikely to vary. But in Wyoming—the place that proclivity is chiseled into the state’s bedrock—there’s an effort to seek the advice of with builders in regards to the affect that their proposals can have on mule deer and different wildlife.
Though these efforts don’t have the power of regulation behind them and are purely advisory in nature, such discussions arm builders with data to minimize adverse outcomes from their initiatives.
Shrubs, Trees, and Grasses
It’ll come as no shock, I’m certain, to be taught that the crops that mule deer eat, sleep underneath, and stroll round are fairly necessary to their survival. Sage, aspen, and bitterbrush are all essential for mule deer, whereas invasive grasses and conifer encroachment are challenges that need to be countered.
Problem: Unproductive Shrub Communities
When shrubs hit a sure age—relying on the precise plant—their dietary high quality drops which makes them much less helpful for mule deer and different wildlife. Fire suppression (mentioned beneath) contributes to this difficulty.
Solution: Sagebrush Revitalization
Lots of on-the-ground conservation efforts contain shrub mowing and mastication—mainly working vegetation by machines that chews it into small items and spits it out. Towing mowers behind giant tractors is expensive and time-consuming, however create exact mosaics of sagebrush that’s perfect for mule deer and sage grouse.
Problem: Invasive Annual Grasses
The difficulty with noxious grasses—cheat grass, Ventenata, medusa head, and others—is that they convert habitat that’s good for mule deer into habitat that isn’t. Annual grasses reproduce by seed every year and are unwittingly unfold by folks by way of roads and trails, in addition to pure means, just like the wind.
Solution: Rejuvra
This is likely one of the extra thrilling developments in mule deer conservation lately. Rejuvra is an herbicide sometimes broadcast by helicopter that forestalls invasive annual grasses from rising for a number of years.
It is comparatively new—barely 5 years previous—and widespread use has solely began within the final couple years, however it’s already yielding good outcomes. In Wyoming alone greater than 100,000 acres of mule deer habitat have been sprayed with it.
Problem: Wildfire—Not Enough and Too Much
Decades of fireplace suppression mixed with persistent drought throughout a lot of the Southwest have created a serious headache for wildlife managers and conservationists.
We’ve painted ourselves right into a nook by permitting the quantity of gasoline to develop to the purpose the place we threat destroying the soil’s capability to nurture plants. Now, when fires do happen, they burn so sizzling that they kill the natural matter within the floor.
Fire suppression additionally degrades the surroundings by breaking the pure burn cycle that enables crops to rejuvenate and sprout younger, nutritious browse. Aspen is a main instance of a plant that sustains deer and elk and that requires fireplace to remain important and wholesome.
Solution: Controlled Burns
In this case, we all know what the reply is: managed (aka prescriptive) burns, coupled with efforts to skinny timber and scale back extra gasoline within the panorama.
But executing managed burns on the required scale is frustratingly tough. The diploma of coordination required to tug one off is formidable. Everyone from native volunteer fireplace departments, landowners, and city officers up by the ranks of federal and state recreation and environmental officers must be on board. And, after all, the climate must cooperate.
Compounding the issue is the necessity for somebody to really give the okay—and be accountable for what occurs. The upshot is that burning is a strong, helpful, and vital device, however deploying it on the dimensions wanted is an uphill battle.
Nowhere is fireplace extra helpful than within the effort to enhance aspen habitat.
“Aspen needs disturbance to thrive and fire is the best tool for that,” says Steve Belinda, chief conservation officer for the MDF. “Any given year we’re doing thousands of acres of aspen work. But because of the administrative hurdles required to burn, we’re generally doing a lot of chainsaw work to cut down conifers and reduce the competition aspens face. In some instances, we can use the conifers as fuel for ground burns to stimulate suckers, meaning new aspen growth.”
The $60 million funding settlement the MDF signed final week with the U.S. Forest Service goals to chop by a lot of that bureaucratic tangle and expedite forest thinning, prescribed burning, and vegetation therapies that won’t solely assist scale back the danger of catastrophic wildfire within the West but additionally enhance mule deer habitat.
Problem: Conifers Run Wild
As Belinda alluded to above, when bushes like Douglas fir, piñon pine, and junipers are allowed to develop unchecked, they shade out aspen, mountain mahogany, and different shrubs, degrading mule deer habitat.
Solution: Chaining and Prescribed Burns
While burning is the best solution to deal with conifer encroachment, loads of the work includes reducing them with chainsaws or utilizing a method referred to as “chaining,” the place heavy-duty chains (consider the type use to anchor an plane provider) are strung between giant tractors and dragged over stands of conifers to knock them down.
“In Arizona we go through a lot of piñon-juniper, grinding it up,” says Bob Jacobs, who sits on the board of administrators on the Mule Deer Foundation and who owns a hearth safety firm in Flagstaff. “Even though piñon-juniper is native, it is out of proportion to what it should be. Fire suppression, grazing, and drought have spurred the spreading of PJ across the landscape. It sucks up water and shades the ground from light, not allowing other plants to grow.”
Solution: Forest Thinning
Not all mule deer dwell in arid areas. Sitka blacktails name the rainforests of coastal Alaska dwelling and one of many points they face is the lack of habitat attributable to poor logging practices.
“Prince of Wales Island had 60 years of clear-cutting that created a lot of [short term] habitat,” Belinda says. “All that forest is reaching second growth and stem exclusion, which means all the sunlight is being eaten up by the crown and no light is getting to the forest floor.”
That’s along with dense grass within the undergrowth that makes the terrain not very practical for animals, Belinda says. “It’s hard to move through and doesn’t have good groceries.”
Because these elusive deer are tough to trace and depend, analysis is required to determine the extent of this difficulty and advocate forestry practices to skinny the maturing second development and make sure the satisfactory fringe areas alongside the seashores that blacktail depend on for meals and canopy.
Human Impact
It’s the basic break-up line: It’s not you, it’s me. In this case, it is us. In the complicated relationship between folks—hunters and non-hunters—and mule deer, we’re the issue.
In the case of hunters, the difficulty is that mule deer are the thing of an excessive amount of consideration and want, making it tough for wildlife managers to steadiness looking alternative whereas sustaining populations of mature males with trophy potential within the context of total herd well being. When it involves non-hunters, mule deer undergo from indifference and neglect (additionally proximity, as talked about within the improvement part above).
Solution: Dealing With Hunter Expectation
Hunters need alternative. They additionally need the possibility to take a mature animal. Some hunters worth meat and time afield over antlers whereas others are prepared to eat a tag so long as an encounter with a heavy-horned brute is feasible.
This is a kind of dynamics that doesn’t have a clean-cut resolution. You’re by no means going to make each hunter completely satisfied, however that doesn’t imply wildlife managers shouldn’t attempt.
Communication is essential. Prior to each looking season in Wyoming, for example, Game and Fish officers meet with the general public to debate adjustments to the rules and administration proposals.
Wyoming additionally surveys hunters after the season and folds that information into its Job Completion Reports that provide an in depth take a look at big-game harvests, administration objectives, and hunter satisfaction. By partaking with the looking public in such a manner, Wyoming mitigates a few of the misunderstandings (and conspiracy-oriented misinformation) that may take root in any other case.
“There is no silver bullet,” says Tator of WGFD. “But it goes back to staying connected with the constituents and understanding what they desire by talking with them and conducting surveys. We’re always trying to answer the question: What would you like from us?”
In addition, it appears there are extra folks throughout the West who’re interested by mule deer and mule deer looking than ever. While this could result in extra engagement with (and funding for) conserving mule deer habitat, it’s an added pressure on the useful resource.
Solution: Dealing with Non-Consumptive Outdoor Recreationalists
One enormous difficulty for mule deer conservation efforts is attempting to persuade non-hunters that their hobbies—whether or not mountain biking, climbing, backcountry tenting, off-roading, or birding—have adverse impacts on deer and different wildlife.
“A lot of these users expect access 365 days a year and don’t understand disturbance ecology,” says Steve Belinda, MDF’s conservation chief.
As a main instance, Belinda factors to the need amongst mountain bikers to ascertain and journey loop trials within the wilderness.
“Bikers don’t like to follow a trail back, they much prefer going in a large loop,” Belinda says. “Animals don’t like to be contained in [such] a loop and will move off, which burns fat or prevents them from putting on fat. That affects birth rates and birth weights, which are critical for fawn survival.”
Some state companies are trying to restrict path use and shut them down for parts of the yr however face stiff resistance from these recreationalists.
“These folks want to be out there all the time and don’t care about deer and elk or pronghorn or sage grouse,” Belinda says.
Another objective to minimize these impacts is by having recreationalists pay for entry or in any other case contribute cash for conservation. But simply as everybody needs to be a gangster till it’s time to do gangster stuff, nearly all of these folks—who would most likely describe themselves as conservationists—have balked when any kind of person charges or different prices have been proposed.
Utah, for example, just lately closed all shed and horn looking till May to minimize the disruptive affect these actions can have on mule deer and elk in gentle of this yr’s harsh winter.
These points will solely grow to be extra acute as locations like Colorado, Montana, and Idaho proceed to expertise important influxes of latest residents, a lot of whom will add stress to an already confused useful resource.
Climate Change
The earth is getting hotter, droughts—that we used to think about as short-term phenomena—have grow to be extra frequent and intense, and we appear to be topic to an elevated tempo of maximum climate.
Naturally, this has made life harder on mule deer and different wildlife. (Though mule deer in Canada are on the rise partially due to these shifts.) These adjustments within the local weather don’t have remoted impacts. They have an effect on lots of the components we’ve already touched on, reminiscent of wildfires, conifer encroachment, habitat loss, and the motion of individuals from drier areas—reminiscent of Texas and California—to the Rocky Mountain West.
Solution: Coping with Relentless Drought
Of all the issues brought on by local weather change with respect to mule deer (and there are too many to totally articulate right here) the one which’s most easy to handle is water.
We’ve been within the midst of an historic drought for many years now and that’s spurred efforts to maintain satisfactory moisture within the panorama. Curiously, the difficulty isn’t only a lack of precipitation but additionally inconsistent rainfall the place some storms do extra hurt than good.
“It appears the timing of when we receive moisture has become highly variable,” says Tator. “So even if we’re still getting 16 inches every year, say, it matters when it comes. We want early season moisture because we want it in the ground during growing season. And we want some amount of moisture to continue throughout the summer. But we’re seeing big breaks in time with no moisture and then you get a dump of four inches–that doesn’t translate to mule deer food.”
More than that, a harsh rain can wash away vegetation that was already struggling from lack of moisture and erode the bottom in such a manner that water is extra vulnerable to flowing rapidly off the panorama.
Four of the simplest strategies to maintain water round—to “rewet the sponge,” within the phrases of 1 biologist—are beaver dam analogs, Zeedyk constructions, spring restoration, and cisterns that seize water and redistribute it over time.
Beaver dam analogs are pretty self-explanatory. They are artifical boundaries that decelerate and maintain again water to create swimming pools and different pockets of moisture. Zeedyk constructions are comparable. Sometimes referred to as one-rock dams, they’re comparatively cheap and straightforward to put in and are used to gradual the stream of water in streams and creeks and mitigate erosion.
Even retaining a modest quantity of water can have an outsized constructive affect. An further little bit of moisture could make browse extra nutritious, caloric, and digestible, giving mule deer higher prospects and assist does with their fawn survival charges.
“Zeedyk structures are meant to keep those areas from unraveling during big rain events,” Tator mentioned. “They help stop deep cuts from occurring and make the areas more resilient.”
In the drier areas of the Southwest a precedence has been to improve cisterns to extend their capability. “We’re replacing 2,500-gallon tanks with 20,000-gallon tanks,” says Bob Jacobs. The tanks catch water after which pump it again into the surroundings, not just for the advantage of mule deer however to assist the rising variety of elk in some elements of the Southwest.
Chronic Wasting Disease
Of all the issues enumerated on this story, CWD is likely to be probably the most intractable and dispiriting. Here are the details as they stand at this time. CWD is spreading throughout the mule deer panorama. It is 100% deadly amongst contaminated elk, mule deer, and whitetails. The most weak people are mature bucks. These mature bucks are probably the most important spreaders of the illness. And CWD has no remedy.
The Problem with CWD Is There’s No Solution
This leaves biologists and recreation officers with no palatable, not to mention “good,” choices to take care of the illness. On the one hand they will let the illness unfold unchecked. This will hasten the introduction of CWD to as-yet uninfected populations and speed up the proportion of deer contaminated in at the moment stricken herds.
The long-term penalties of this method are doubtlessly catastrophic. Barring the emergence of some kind of pure immunity—which we’ve but to see happen within the a long time of monitoring the illness—it might imply the digital disappearance of older age-class mule deer bucks. In this future, a 3 ½-year-old 140-point muley is likely to be nearly as good because it will get, as a result of they received’t survive past that time to develop greater.

High charges of an infection may trigger herd numbers to say no, each from the deadly nature of the illness, but additionally from the elevated problem for mule deer does to have sufficient fawns to switch grownup deer succumbing to CWD.
Whitetails within the Midwest, which have a lot larger reproductive success, aren’t as weak on this regard, however for Western mule deer, which have already got a tough time of it, this might push them previous a tipping level.
Some mule deer herds in Wyoming and Saskatchewan have already got CWD infections charges of 60 to 70 % in bucks. How these herds fare might give us a glimpse of the longer term prospects for the specie.
On the opposite hand, the opposite solution to deal with the issue isn’t fairly both. It includes capturing most, if not all, deer in notably sizzling CWD areas. This method is favored by many biologists because it appears to be one of the simplest ways to gradual the unfold of the illness to uninfected herds.
Maybe it’s the least unhealthy possibility, however the rationale smacks of the Vietnam War technique of burning a village down with the intention to reserve it. Even amongst wildlife professionals, this “solution” leaves a nasty style of their mouths, whereas most hunters viscerally recoil towards the concept.
The idea is a tough one to swallow. Basically, it says that the realm you prefer to hunt now, which has good (or affordable) trophy high quality ought to be sacrificed as a result of at some unknown level down the street—15 years? Longer?—there received’t be any trophy bucks, or the potential for trophy bucks, in any respect. It’s a tricky promote.
Predators
CWD won’t have an answer, however in most hunters’ eyes, there’s a simple repair to coping with predators that key on mule deer: take away extra of them from the panorama by looking and trapping. Depending on geography and time of yr, black bears, coyotes, wolves, and mountain lions all prey on mule deer—however the precise affect of their predation is usually poorly understood and, in lots of instances, overstated by the overall looking public.
“Generally, predators are part of the system and when they are managed and balanced with prey species, the animals they take don’t have a big impact on mule deer numbers,” Tator says. “But when populations are already suppressed through habitat issues, bad winters and other factors—adding predation on top of that creates the potential for predators to have a negative effect.”
Solution: Predator Hunting
If you need to do one thing to guard mule deer from predators, go hunt black bear this spring. While you’re at it, kill some coyotes in April round mule deer fawning grounds. Those two actions may really avoid wasting mule deer.
A standard chorus amongst hunters is that grownup mountain lions eat a deer every week, in order that by killing one mountain lion you’re saving 52 deer a yr. The fact is extra complicated, and tough to quantify than that.
“Lions by their nature are secretive. They are hard to count. And there’s a small, specialized group who are good at killing them,” Tator says.
In gentle of the strict quotas positioned on mountain lion hunts, the concentrate on simply taking giant males (which some research point out merely encourages extra lions to maneuver into the panorama), the complicated interaction between mountain lions and different predators, and the absence of dependable numbers, it’s a stretch to attract conclusions about the advantages of mountain lion looking on mule deer populations.
That mentioned, in sure circumstances, growing mountain lion looking alternatives has been proven to assist mule deer.
Bob Jacobs pointed to an instance of a looking unit in Utah the place mule deer had excessive fats content material—which means they have been consuming effectively and comparatively unstressed. When mountain lion looking quotas have been elevated in that space, mule deer numbers improved. In distinction, he mentioned there was a case the place growing the lion quota on extra confused deer with decrease physique fats didn’t yield the identical profit. That appears counterintuitive, but it surely illustrates the complexity of managing predators for mule deer.
Solution: Cause-of-Death Studies
Utah has led the way in which in putting collars on mule deer to assemble all types of knowledge, together with monitoring causes of deer mortality. Over the final eight years, the state has captured and collared some 5,000 deer. During this time, Utah has been in a position to collect about 1,500 collars from deer which have died to research the info.
Wyoming is following swimsuit and just lately collared 1,000 mule deer. Those 1,000 deer are unfold throughout 5 main inhabitants teams of greater than 200 people every, and two of these teams, or 400 deer whole, are being particularly investigated to check explanation for demise, Tator says.
That five-year Wyoming examine, together with the continuing efforts in Utah, will assist unravel a few of the mysteries relating to mule deer mortality. Whenever a collared deer dies, wildlife officers will gather the carcass to find out the trigger, whether or not from predators, pick-up truck bumpers, illness, or marginal habitat.
Final Thoughts on Mule Deer in 2023
There’s no scarcity of effort to assist mule deer. But as a result of the threats dealing with them are multifaceted, interrelated, and regionally particular there are not any one-size-fits-all solutions. If all politics are native, the solutions to the woes besetting mule deer are much more so.
When Lewis and Clark wrote about “deer of the Mule kind” throughout their voyage of discovery—giving mule deer their identify—that they had no inkling what that “curious kind of deer” would come to imply to generations of conservationists and hunters.
So regardless that the challenges dealing with mule deer are steep—some seemingly insurmountable—it’s exhausting to not be hopeful when you think about the hundreds of thousands of {dollars}, hundreds of volunteers, and a whole bunch of educated biologists and wildlife professionals who’re within the mule deer’s nook, preventing on their behalf.
