A study on Wyoming\u2019s largest moose herd could guide management decisions about oil and gas leasing in the Wyoming Range, south of Grand Teton National Park.<\/p>\n

The Wyoming Game and Fish Department, and the Wyoming Cooperative Fish and Wildlife Research Unit recently expanded a moose project in the Northern Wyoming Range between Jackson and Pinedale.<\/p>\n

Researchers collared 65 moose and fitted the animals with satellite tracking collars during the past three years to learn about their use of habitat, migration patterns and survival. An additional 28 cows were fitted with collars this winter between Cottonwood Creek and the upper Hoback River. Of those, 12 are wearing collars that provide real-time daily locations, a press release said. The other collars are set to fall off after two years and then the data can be downloaded. This winter, researchers also documented body condition using ultrasounds of rump fat.<\/p>\n

\u201cIt\u2019s pretty cutting edge stuff,\u201d said Mark Gocke, with Wyoming Game and Fish.<\/p>\n

While other animals, like mule deer and elk, have been studied in relationship to oil and gas development, moose haven\u2019t. Moose in some areas of the state, like in the Snowy Range or the Big Horns have been thriving. But in western Wyoming, herds have struggled.<\/p>\n

The study is trying to figure out what changes are happening in the herd and what are the causes,\u00a0Gocke said.<\/p>\n

\u201cIt\u2019s going to be pretty enlightening information for everybody,\u201d he said.<\/p>\n

The study originally started as a way to gather baseline data on the moose population, including nutrition, migratory routes and times, as well as winter and summer range, before Plains Exploration and Production Co. (PXP) began plans to develop oil and gas leases in the area, said Jake Goheen, assistant professor in zoology and physiology at the University of Wyoming.<\/p>\n

The Sublette Moose herd is the largest in the Intermountain West in the lower 48 states, he said. Since research began, PXP sold its leases to the Trust for Public Land, which raised money through donations to buy and retire the leases from future development. With the PXP leases retired, focus has now shifted to 44,700 acres that were leased before the Wyoming Range Legacy Act passed in 2009 and retired 1.2 million acres in the Wyoming Range from oil and gas development. The legislation left the fate of those acres up to the agencies, and Bridger-Teton National Forest staff are still studying the acreage and haven\u2019t yet issued a decision. Recent interest from Stanley Energy in exploring within those acres could threaten moose, Goheen said. The Bridger Teton National Forest is currently analyzing possible alternatives for the proposed development that includes South Beaver, North Horse, and Cottonwood creeks in a Supplemental Environmental Impact Statement (SEIS).<\/p>\n

Although moose are relatively abundant in this area, very little is known about their demography or habitat use.<\/p>\n

The expanded study, which focuses on moose south of the original study area, is an attempt to gather baseline data on the herd, Goheen said. The information will provide land managers with the best possible science as they evaluate projects in the area.<\/p>\n

\u201cThis isn\u2019t really a question about will energy development disturb moose,\u201d Goheen said. \u201cThe answer is most likely yes. The question is how we can mitigate those impacts if development occurs.\u201d<\/p>\n

The study is unusual in that it is proactive, he said. Often wildlife management is reactive. Having data ahead of time will help managers find the way to limit impacts on the moose herd if the area is developed.<\/span><\/p>\n

The study has already yielded surprises. First, the Sublette Moose population has a low pregnancy rate, about 74 percent this year, and when averaged with even lower rates in the previous years, it is the lowest documented rate\u00a0in the lower 48 states and much lower than the Jackson moose herd, commonly at 90 percent, he said. But the calf survival rate in the Sublette herd is higher than the Jackson herd, he said.<\/p>\n

The herd also appears to be\u00a0partially migratory, meaning some move, but some \u2014 about 40 percent from an initial small sample \u2014 stay in the same place, which is unusual, Goheen said. That means researchers need to look at the habitat conditions of the area. They also need more data from a larger sample size, he said.<\/p>\n

The study is important because it will help show why pregnancy rates are low in the herd, because it separates nutrition and predation as factors, said Steve Kilpatrick, executive director with the Wyoming Wildlife Federation. The study will provide a clearer understanding about what is driving calf-cow ratios, he said.<\/p>\n

\u201cAnytime a species is having lower reproductive rates than expected, we want to know why it\u2019s happening,\u201d he said.<\/p>\n

It also offers important baseline data on the health of the herd before outside factors like development.<\/p>\n

\u201cPregnancy rates show that those moose are obviously under some sort of stress,\u201d he said. \u201cIf we add another stressor, like energy development, then we have some baseline information to compare pre- and current development.\u201d<\/p>\n

Even if the area isn\u2019t developed, the data on the herd is important because little ecology information on it existed. Moose\u00a0are a sensitive species and often a good sensor for changes in the environment.<\/p>\n

\u201cIf we are doing something wrong, they\u2019ll be one of the first ones to show us,\u201d he said.<\/p>\n

Many of Wyoming\u2019s moose populations have suffered marked declines over the past several decades, particularly in the western part of the state, according to Game and Fish. After experiencing a sharp decline that started during the mid-1990s, the Sublette herd stabilized, though numbers remain below the herd population objective set by Wyoming Game and Fish Department.\u00a0The Sublette moose herd is the largest in the western United States, with about 5,000 animals spanning an area from Hoback Junction to LaBarge to Pinedale to Afton. Those moose bring in tourism dollars from hunters, photographers and wildlife enthusiasts, while also maintaining an important role in the ecosystem, Goheen said. \u00a0\u201cThey are important to the ecology and the economy of the area.\u201d<\/p>\n

Plus, Kilpatrick added, everyone likes moose. \u201cThey are so darn ugly they\u2019re cute and they cause little conflict with land owners.\u201d<\/p>\n
