Southwest Colorado elk herds in jeopardy

Southwest Colorado elk herds in jeopardy

DURANGO — The way forward for elk in Southwest Colorado is in jeopardy.

Over the previous few years, herds in the area have been slowly dying off, and wildlife officers are involved concerning the iconic ungulate’s means to outlive in wholesome numbers in the long run.

The difficulty includes a thriller: About half of the elk calves born in Southwest Colorado die inside six months. Of the survivors, one other 15 % perish earlier than they flip a yr previous.

And researchers don’t know why, The Durango Herald studies.

The issue encompasses wildlife mismanagement: After document excessive elk populations in the 1990s, the Division of Wildlife (now Colorado Parks and Wildlife) ordered a mass hunt to chop again the animal’s numbers.

These similar elk herds at the moment are struggling to get well.

And, there are pressures from an avid consumer group: hunters, who in huge numbers journey to Colorado’s wealthy public lands. On prime of killing elk, they will disrupt breeding habits and future offspring.

The problem of understanding the forces behind this inhabitants decline comes at a time when Colorado will restructure the best way it carries out big-game searching seasons, which, amongst conservationists and hunters alike, presents a chance to assist elk recuperate.

“I’ve been hunting in this area since 1993,” stated Thomas Downing, an archery hunter and supervisor of Gardenswartz. “What I’ve witnessed, firsthand, is our elk herd is not in healthy shape.”

By the early 1900s, Western settlers had worn out almost all the elk in North America, bringing an estimated inhabitants of 10 million down to only 40,000 animals all through the USA and elements of Canada.

The U.S. Forest Service in 1910 estimated simply 500 to 1,000 elk roamed the complete state of Colorado.

To revive the inhabitants, the state banned elk searching till the early 1930s, and elk from Jackson Gap, Wyoming, have been transplanted into 14 areas across the state, together with the Hermosa Creek valley, north of Durango.

These restoration efforts have been extremely profitable. Colorado now boasts the most important elk inhabitants – about 280,000 animals – in North America.

In Southwest Colorado, elk herds loved a protracted interval of prosperity in the 1990s, a time many hunters keep in mind fondly.

“It was wonderful,” stated David Petersen, a lifelong hunter, acclaimed naturalist and author on searching ethics. “And it just got better and better. Lots of elk. Lots of bulls. Elk bugling everywhere, all the time.”

However the excessive was short-lived.

Elk are hungry grazers, consuming between 15 to 21 kilos of meals a day.

In the summertime, the ungulates favor to remain in the excessive county, feeding on grasses, forbs and shrubs.

However in the winter, small bands are likely to coalesce into giant herds to spend the chilly months feeding at decrease elevations, in areas now occupied by farms and ranches.

Consequently, it’s not unusual that elk trigger a good quantity of injury to fields and crops and compete with livestock.

Towards the late 1990s, with elk plentiful on the panorama, ranchers and farmers pressured the Division of Wildlife to scale back their numbers. And the company responded, aggressively, by permitting extra hunters to hunt.

Particularly, the Division of Wildlife issued a digital free cross for killing cows. However killing too many females additionally started to kill the animal’s potential to breed.

On the peak of the uncontrolled culling, a complete of three,500 searching tags have been issued in 1996 for the cow harvest in two herds round Durango.

This era, against this, is a time remembered not so fondly.

“During some private-land cow hunts, I saw elk falling dead by the dozens a day,” Petersen stated. “It was an ugly slaughter. They hit the elk cows especially hard for several years.”

Within the San Juan herd, which ranges from the Animas River east to Wolf Creek Move, about 23,000 elk have been reduce right down to about 17,300. Within the Hermosa herd, a inhabitants of about 6,500 was decreased to four,100.

Scott Wait, a senior terrestrial biologist for Colorado Parks and Wildlife, stated that whereas these numbers don’t drastically stand out, they’re vital in the complicated artwork of massive recreation administration. And, in retrospect, many individuals felt the discount effort was too aggressive.

“Maybe we were too successful, or maybe the public tolerance has changed,” Wait stated. “Regardless, we did decrease elk to the point of dissatisfaction.”

The inhabitants discount alleviated conflicts with ranchers and farmers. The issue is, the trouble went too far. Now, elk herds are under their desired inhabitants ranges and a brand new host of points threaten their restoration.

“In the last six to eight years, we’ve tried to go back into the population growth phase,” Wait stated. “But we are struggling getting the population of elk to grow again.”

Each winter, Colorado Parks and Wildlife screens elk populations from the air by helicopter.

To find out how herds are doing, probably the most useful numbers for wildlife officers are the ratios of cows to calves. If the ratio is excessive, populations are secure, and more likely to develop. If the ratio is low, it’s an indication herds are beginning to wrestle.

About 15 years in the past, there have been anyplace from 50 to 60 calves for each 100 cows, thought-about a robust stability. In recent times, nevertheless, that quantity has fallen to about 20 calves per each 100 cows.

Nobody’s fairly positive why these numbers have fallen, Wait stated, although it doesn’t look like a problem with being pregnant. About 90 % of pregnant cows give delivery to wholesome calves.

To additional muddle the state of affairs, the calves aren’t surviving the primary yr of life. Once more, nobody’s fairly positive why. Illness and assaults by predators have been dominated out as potential culprits, Wait stated.

Whereas elk populations seem secure in the northern elements of the state, these points have surfaced in some elk herds to the south.

A analysis undertaking in its second yr, based mostly in the Montrose and Trinidad areas that are seeing comparable points, seeks to realize info by placing radio collars on elk calves and following them by means of youth.

“We are seeing significant mortality in those first six months,” Wait stated. “This new technology allows us to study those months, which are the mystery, and determine a cause of death.”

For native hunters, the reply to the elk’s decline isn’t going to be discovered in research or via pc analytics. One wants solely to look to the backcountry for solutions.

Each fall, hunters from everywhere in the nation come to Southwest Colorado to scour the San Juan Mountains for giant recreation. However this annual ritual for hunters occurs to coincide with some of the essential occasions of the yr for elk: the rut.

The rut is when elk congregate in giant numbers, and in grand style, male elk, referred to as bulls, spar for the appropriate to breed with the cows. That is when bugling, the loud name of the bull elk to draw cows, may be heard all through the forest.

Petersen, an elk skilled who has been searching in the mountains outdoors Durango since 1981, stated this show and its timing are delicate.

After the rut begins in mid-August, elk sometimes breed the final week of September or first week of October. This enables calves to be born in late Might and early June, giving the newborns sufficient time to bulk up earlier than having to outlive the subsequent winter.

If this course of is disrupted in anyway, it might imply late delivery for calves and a decrease probability of surviving the winter, Petersen stated.

“That’s why it’s so important that the rut happens on time,” he stated.

However Petersen believes the quantity of hunters in the forest in September is pressuring the elk and disrupting the rut. Consequently, he’s seen breeding occur as late as November, creating hardships and danger for late-born calves the subsequent spring.

Based on Colorado Parks and Wildlife stats, almost 13,000 hunters trekked into the San Juan Mountains to hunt the Hermosa and San Juan models final yr.

“There’s an extreme, excessive hunting pressure in September,” Petersen stated. “There are just too many hunters at this most delicate time of year for elk.”

Dan Parkinson, an area hunter and advocate with Backcountry Hunters and Anglers, stated with fewer elk and extra hunters, the searching expertise has drastically diminished in the San Juan Mountains.

Within the previous days, he stated, a hunter might work onerous sufficient and get far sufficient again into steep and deep nation to seek out undisturbed elk.

“But now you get back in there, find out that there are other hunters in the area with the advent of mapping capability,” Parkinson stated. “There are no secret spots out there anymore.”

A mixture of forces – searching pressures, drought, habitat loss – might be stressing the elk. Nevertheless, Petersen and others consider the hunt is a minimum of one issue wildlife managers have tangible management over.

The large query for hunters can be whether or not they’re prepared to sacrifice some alternatives for the betterment of the herd.

Each 5 years, Colorado Parks and Wildlife restructures the best way it manages searching seasons in the state, resembling what number of searching tags it can challenge for a selected area and when the varied types of searching (archery, rifle) start and finish.

Native hunters stated this must be a time of intense self-reflection for the searching group, and a time hunters ought to contemplate daring modifications to the best way the hunt is presently structured.

Downing, who manages a retailer that sells searching gear, advised limiting the variety of searching tags issued throughout rifle season. And, he advised a cap on tags for archery season, which presently is limitless.

He stated the restructuring must bear in mind all the opposite searching seasons like deer, turkey, grouse, black bear, and so forth., which deliver much more hunters into the backcountry concurrently elk hunters.

“We need just something so we don’t have that many people in the field at one time,” he stated.

Petersen agreed. He stated Colorado Parks and Wildlife must radically scale back the variety of cow tags for a number of years, maybe suspending the hunt on females till the inhabitants recovers. And, he added that muzzle-loading rifle season shouldn’t occur in the center of the rut.

“Biologically, morally this is wrong,” he stated.

Colorado Parks and Wildlife did minimize cow tags for rifle season by 75 %, Wait stated, nevertheless it hasn’t proven any constructive impact in rebounding populations.

“If we eliminated rifle cow-elk harvest, it would probably start to increase the population a little bit faster,” Wait stated. “But I question the fairness of that.”

As an alternative, can hunters and the general public come collectively and comply with strike a stability between permitting the custom of searching whereas preserving the hunted? Downing thinks so.

“I think hunters will ultimately come together for the good of the herd,” he stated. “At heart, we’re a bunch of conservationists, and hunters here locally know this.”

Native hunters worry that politics have infiltrated what ought to be an company that promotes and preserves wildlife.

Colorado Parks and Wildlife’s laws and insurance policies are set by the Colorado Parks and Wildlife Fee, an 11-person committee appointed by the governor that pulls individuals from various pursuits.

However many, like Petersen and Parkinson, say the fee is just too heavy with individuals representing agriculture and business pursuits, which most of the time, butt heads with wildlife pursuits.

And in addition most of the time, wildlife comes out on the dropping finish.

“CPW has always been cowed and bullied by ranchers and farmers who detest wildlife,” Petersen stated. “For any real progress, we need to pull the wildlife commission out of the political arena. And that may need to be done through legislation.”

Of the 11-person fee, three individuals characterize agriculture and two individuals characterize business pursuits. Two individuals sit on the board for the pursuits of the outfitting business and one represents sportsmen.

Don Brown, Colorado’s commissioner of agriculture, additionally sits on the board, although he isn’t voting member.

There are not any wildlife biologists, ecologists or specialists on the board tasked with managing wildlife in the state.

Michelle Zimmerman, who represents leisure pursuits on the fee, agreed that sportsmen and agriculture pursuits have a dominant voice as a result of, traditionally, these teams have all the time been probably the most concerned.

Zimmerman stated that as Colorado’s demographics and priorities change, so ought to the wildlife fee.

“I think the commission should evolve to best reflect the demographics of the state while remaining committed to the sportsmen and women and ag interests that have supported the mission of the agency for decades,” she stated.

The best way Colorado Parks and Wildlife is funded has additionally been referred to as into query. One of many company’s major supply of funding is thru the searching tags it sells. Parkinson stated that reliance makes the company much less prepared to scale back these numbers.

“There needs to be discussion how to find a sustainable way to fund wildlife conservation in the state of Colorado,” he stated.

Colorado Parks and Wildlife’s complete income in fiscal yr 2016-2017 was $241.9 million. Of that quantity, $6.5 million got here from 158,000 in-state residents shopping for searching tags. A complete of 70,400 out-of-state tags generated $40.three million.

Colorado Parks and Wildlife will begin its rescheduling of searching seasons this winter, which can contain public remark. The brand new schedule would take impact in 2020.

It’s a glimmer of hope on the proper time, although not a magic bullet. Whereas restructuring the searching season might assist relieve stress on elk, the trigger might very nicely be points with local weather change, resembling drought, unexpected illness or habitat loss.

Or a mixture of all these elements, Wait stated.

Gardenswartz’s Downing stated one other consequence of the declining herds is that enterprise on the downtown Durango store has been down.

“We’re starting to see a decline in hunters coming to our town because the word has spread our elk herd is struggling down here,” he stated.

Downing, now 49, has hunted in Southwest Colorado since he was 7 years previous. In 35 years of searching, he has by no means killed a feminine elk.

“I don’t feel right about it,” he stated. “If she doesn’t get killed, and lives to 20 years, she’s giving birth to 20 calves.”

He’s additionally able to make the most important self-sacrifice: giving up these serene autumn days in pursuit of prey.

“I can’t imagine a year in my life not elk hunting,” he stated. “But with the current condition of our elk herd, I would not be upset if I wasn’t able to hunt for a year or two, so long as the long-term results of that sacrifice bring the elk herd back.”
