COLORADO DIVISION OF WILDLIFE HONORS RANCH OWNERS FOR CONSERVATION WORK

August 10, 2008

Former media magnate Malcolm Forbes was not only a leading innovator in magazine publishing; he also helped to pioneer private-land wildlife management practices in Colorado. To honor the Forbes family’s efforts in wildlife conservation, the Colorado Division of Wildlife recently thanked the Forbes Family for its nearly 40 years of work at the 173,000-acre Forbes-Trinchera and Forbes-Blanca Ranches in the San Luis Valley.

In the fall of 2007 the Forbes family sold the ranch to Louis Bacon, an East Coast resident who owns numerous other parcels of land throughout the United States which are managed for conservation and wildlife purposes. In Colorado, Bacon also owns the 20,000-acre Tercio Ranch that is located southwest of Trinidad.

Bacon has announced that his new property, located in the San Luis Valley, will now be called the Trinchera Ranch and the Blanca Ranch. It will continue to be managed for wildlife, natural resource and environmental values. The ranch  will continue to work cooperatively with the Division of Wildlife on various conservation projects and participate in the DOW’s Ranching for Wildlife program.

“The Colorado Division of Wildlife is grateful to the Forbes family for their wildlife conservation philosophy,” said Tom Spezze, southwest regional manager for the DOW.

“Not only did the family bring great ideas, but they hired an outstanding staff to do the work to make this one of the premier wildlife habitat areas in Colorado.”   Spezze made the remarks at a reception held at the Trinchera Ranch in late July.

Tom Remington, director of the DOW, praised the Forbes ranch for its work on a variety of projects that have helped conservation efforts throughout Colorado. These include: establishing a herd of Rocky Mountain bighorn sheep, re-introduction of Rio Grande cutthroat trout, and numerous habitat improvement projects aimed at helping big game populations.

“The ranch is a leader in wildlife conservation work,” Remington said. “The people here proved what can be done. Today, the division of wildlife uses many of the management techniques developed here in projects all over the state.”

Malcolm Forbes purchased the property in 1969 and decided quickly that wildlife should be a priority. Former DOW biologist Errol Ryland was hired to manage the property. Ryland and DOW staff developed the Ranching for Wildlife concept at the ranch. Today, 16 ranches that comprise more than 1 million acres of prime big game habitat participate in the Ranching for Wildlife program.

In the late 1980s, 3,000 domestic sheep were removed from the ranch and 34 Rocky Mountain bighorns were transplanted from British Columbia. Now the herd on the ranch numbers more than 300. Over the years, the ranch has allowed the DOW to trap sheep and move them to other parts of the state.

After Ryland retired in the early 1990s his son, Ty Ryland, took over as ranch manager.   In Dec. 2004, the Forbes family placed approximately 81,400  acres of the Trinchera Ranch under a permanent conservation easement. None of that land will ever be developed. Bacon is now considering placing a conservation easement on the 90,000-acre Blanca Ranch. This portion of the property contains three of Colorado’s 54 famed 14,000-foot mountains – Blanca Peak, Little Bear Peak and Mount Lindsey.

“Mr. Bacon believes that the Blanca Ranch is an unique property and it ought to be protected for future generations,” a spokesperson said.

Christopher Forbes, Malcolm Forbes son, said the family was pleased to find a new owner who was also conservation-minded.   “We couldn’t have found a better conservation steward in America than Louis Bacon,” Forbes said.

Bacon explained that continuing resource conservation on the property is his top priority for the ranch.

“I feel a duty to continue the conservation legacy established by the Forbes Family; and to help us we’ll continue working with the DOW,” Bacon said.

Bacon also said that staffing at the ranch won’t change. The ranch employs about 30 people in Costilla County.

Under the Ranching for Wildlife program, participating owners work to improve habitat, develop wildlife management plans with the DOW, and allow a limited number of public hunters at no charge. In exchange, ranch owners are allowed to set special seasons for private hunters.

Public licenses on the Trinchera Ranch include: 10 bull elk and 75 cow elk; 10 mule deer bucks and 75 does; two big horn rams and nine ewes. The ranch leads about 50 private hunters each year.

Mule Deer Study

August 10, 2008

DOW BIOLOGISTS STUDYING MULE DEER AGING

Early results of a mule deer aging study being conducted by the Colorado Division of Wildlife are helping provide insight into the trade-offs between hunt quality and hunting opportunity in southwest Colorado.

The DOW asked hunters to submit teeth from bucks harvested in Game Management Units 54, 61, 62, 80 and 81 during the 2007 big game season. Biologists determine the exact age of a mule deer by counting the annual growth rings present within an animal’s incisors. The DOW sent mailings to 2,065 hunters in 2007 explaining the project and asking them to send teeth from harvested bucks. Last year, 375 teeth were returned.

Biologists plan to continue this research for the next two hunting seasons.

“The return rate in 2007 gave us an excellent sample to start with,” said Brandon Diamond, a terrestrial biologist for the Colorado Division of Wildlife in Gunnison. “There are three management units involved in this project that have contrasting buck-to-doe ratio objectives. GMU 54 has the highest ratio followed by GMUs 61 and 62, and finally GMUs 80 and 81.”

The results show that the age structure of bucks harvested varies between the GMUs, as biologists anticipated. “The purpose of this study is to determine that in units where we manage for high buck-to-doe ratios that hunters actually are taking more older-age-class bucks,” Diamond said.

Biologists are interested in evaluating whether there is an optimum buck-to-doe ratio to which they can manage that maximizes both hunt quality and opportunity. “Hunters across the west love to see big mule deer bucks. But they also want the chance to hunt them on a regular basis. We are trying to find the best middle ground,” Diamond said.

GMU 54, just north of Gunnison, has in recent years become renowned for its mule deer. It is managed for a high buck-to-doe ratio of 40-45 bucks per 100 does; the 2007 post-hunt population estimate was approximately 7,500. Despite the tougher hunting conditions during the 2007 seasons due to unseasonably warm and dry weather, the first-year results of this project are really interesting, Diamond explained.

“In unit 54, the majority of hunters submitted teeth from bucks that were between 3-6 years old.  It appears we have a lot of bucks that are 4 years or older, which should be the case due to our management prescriptions.  Because of current management, hunters can be selective and they are seeing greater numbers of older bucks,” Diamond said.

In GMU 54, bucks up to 9 years old were harvested.

“Maintaining so many older-aged bucks, however, doesn’t come without sacrifice,” Diamond explains. “In many southwest Colorado deer units, deer hunters will have to sit on the sidelines for several years between hunts.

Many hunters would like to hunt deer every year and have the opportunity to harvest a buck four years old or older. The reality is that you can’t have it both ways.”

GMUs 61 and 62 are located on the Uncompahgre Plateau, west of Montrose. This area provides excellent deer habitat. The estimated population is 32,000, and the sex ratio is estimated at 35 bucks per 100 does. Teeth submitted from hunters in 2007 were predominately between 1 and 4 years old; however, some bucks as old as 9 years were harvested.

In GMUs 80 and 81 in the San Luis Valley the deer population is estimated at 5,900 with a buck-to-doe ratio of approximately 24 to 100. Most of the bucks harvested in the area were from 1 to 3 years old, with a few bucks as old as 7 years.

The DOW is urging hunters in these units to send in teeth from the harvested animals, particularly in GMUs 62 and 61 which had the lowest overall response in 2007. Overall, Diamond hopes to collect about 1,000 teeth as the study continues for the next two years. This project will also help managers evaluate the changes in mule deer populations following the severe winter of 2007-2008.

“We have made it as easy as possible to participate in this project, so hopefully hunters will take a few minutes to send in their tooth,” Diamond said. “The bigger the sample size, the more we’ll learn about how our deer management prescriptions are working.”

The DOW hopes to continue this project through the fall of 2009 so that three years of data are available for comparison.  For the 2008 season, hunters can expect age results by May or June of 2009.  Results will be posted on the Division of Wildlife’s website as soon as possible so that hunters may check the age of their individual deer on-line.

Hunters who have drawn tags in these units may receive an envelope and a letter of explanation before the start of the 2008 season. In some units, a sub-sample of hunters was selected to participate in the project, so not everyone will receive a mailing. Only those who harvest bucks are asked to send in teeth.

Thanks to a generous donation, hunters who send in teeth in 2008 will have a chance to win a rifle donated by the Mule Deer Foundation.

if you hunted in any of the units last year and you sent in teeth, you can check the age of your animal on the DOW web site. Go to: http://wildlife.state.co.us/Hunting/BigGame.
