In the past decade, over 45,000 acres of land in southern Utah have had conservation treatments by removing the encroaching pinyon-juniper forest and allowing the native grasses and sagebrush to return.Decreasing the Habitat Risks of Utah’s Southern Sage-Grouse
With the use of GPS units, scientists and manager are able to witness the positive impacts these treatments are having on Utah’s Greater sage-grouse population. They monitor the movement patterns of the grouse and determine how the birds use their seasonal habitats throughout the year.

Female and male grouse have similar habitat needs during the winter, but choose different landscapes when their needs change during the nesting and chick-rearing seasons.

Wildlife managers call the grouse a “landscape species” because they have to manage a variety of different communities for the grouse to thrive.

During the months of January and February when the habitat is at its coldest, females and males have the same needs – to stay warm, find food, and avoid predators.

Fortunately, sagebrush provide the resources to meet all these needs.

While grouse huddle under the brush for protection from frigid winds, deepening snow and roaming predators, they avoid having to search for food since the bulk of their nourishment comes from the leaves of the sagebrush. The grouse simply reach up, nibble on the leaves, and remain safe in their protective sagebrush tent.
When they have consumed all the leaves from one bush, they simply move to another sagebrush.

In the spring, the needs of the females change dramatically. Once their chicks have hatched the females search for a moist place where the chicks can eat a variety of bugs and green vegetation to receive the necessary nutrients for fast growth.

By fall, the chicks are grown and the adult females return to the dry sagebrush habitat and prepare for winter.
The biggest struggle sage grouse have in the southern region is a fragmented habitat. They have to fly dangerous distances to reach the variety of habitats they need.

Nick Frey, extension associate professor in the Department of Wildland Resources at USU, has researched sage grouse for the past 13 years. She explains this struggle, ”To get to the next tiny pocket of habitat [the grouse] have to fly over forests and high ridges, which endanger their lives. Prior to the treatments, it was difficult for me to have a bird stay alive for an entire year, now I have birds I have tracked for more than three years…They’re able to find better resources and healthier habitats without putting themselves at risk so often.”

One of the first conservation treatments occurred in Sink Valley in 2005.

Prior to this, female Greater sage grouse in Sink Valley would spend the summers in the agricultural fields south of Alton, which were laced with danger. A couple of times grouse got bailed up and researchers would find the transmitters in a hay bale. At other times, an eagle would carry off birds and the transmitter would be found with a hole in the side from the eagle’s claw.

Within two years after the Sink Valley treatment, researchers stopped finding females anywhere close the agricultural fields. The sage grouse were now able to find grasses and forbs in close proximity to their nests.
Rhett Boswell, Habitat Biologist at Utah Division of Wildlife Resources, who created management tools using Frey’s GPS data explains, “With this GPS [data] we have learned so much, it keeps opening up new opportunities to refine our management prescriptions. With this best available science, we can identify which management treatments have the greatest positive impact and create resource selection models to plan future management.”
In other words, the future of Utah’s Greater Sage Grouse is looking bright.

So what happens when you get a bunch of ranchers together with a bunch of scientists and agencies? I found the answer as I attended a meeting in a remote part of western Boxelder County a few evenings ago. I was pleasantly surprised to discover much good for both wildlife and people.

This was a formal meeting under the auspice of the West Boxelder Conservation Resource Management (CRM) Group targeting greater sage grouse recovery. It was a very informative meeting covering everything from juniper forest removal, prescribed burns, and reseeding to enhance range for cattle, birds, and wildlife.

I learned that due to wildfire suppression which is essential to maintaining healthy range conditions, juniper forests have replaced thousands of acres of grasses, forbs, and sage steppe communities. I was also informed that pinyon pine will be preserved honoring Native American traditions which is central to their culture and diet. In addition to this work, the group addresses general rangeland condition and invasive species.

The CRM is planning wetland and riparian improvements that will provide resting, feeding, and nesting sites for migrating birds. Fencing has been put around key springs and off-site water sources have been developed. The reintroduction of beaver to the stream will help the extremely limited water supply by slowing the spring water runoff, stabilizing the stream banks, and raising the water table.

There was a lively exchange regarding a paper published in a respected science journal by USU authors addressing grazing impacts on grouse populations. The Greater Sage Grouse has become a species of special concern due to plummeting populations, and is considered an umbrella species being its recovery should be paralleled by other sensitive faunal species.

A statement in the papers abstract “Our meta-analysis revealed an overall negative effect of livestock grazing on grouse populations.” raised some red flags with the ranching community. Reading further, this study was conducted on a different grouse species in the U.K. There appeared to be a peaceful resolution to this concern and agreement that future abstract wording would get more scrutiny before published.

I also learned the verdict is still out on grazing impacts on the greater sage grouse. Intense research is underway in the CRM attempting to find answers. My prediction is with all of the range restoration activity combined with well managed grazing will eventually result in higher grouse populations.

This good work has not gone unrecognized. In 2016, the West Boxelder CRM was presented with the Sage Grouse Habitat Stewardship-Collaborative Award from the BLM as an ideal example of a community-based land stewardship organization that is committed, engaged, and active across land ownership boundaries. A tip of the hat to all interests on this remarkable effort!

Greater Sage-Grouse in Utah

Utah’s dry, sagebrush covered landscapes are home to one of North American’s largest grouse species, commonly known as the greater sage-grouse.

The females are attractive chicken-size birds with gently curved bodies. Their feathers show streaks of black, brown and gray. This pattern acts as a natural camouflage in their sagebrush habitat to help protect them from predators.

Males are distinguished from females by their majestic form and decorative feather patterns. They are often twice the size of females and can weigh over seven pounds. A thick layer of white plumage covers the males’ breast and wraps up around both sides of their thick necks. Their tails are a long spray of pointy feathers, which rise into a beautiful fan during courting season and provide the basis for their scientific name Centrocercus urophasianus derived from the Greek word “kentron” meaning spiny, “kerkos” meaning tail, and urophasianus meaning tail of a pheasant.

To help protect against predators their wing and back feathers have streaks of black, grey, and brown – similar to the females.

Buried under the male’s white breast feathers are two air sacs that remain concealed until mating season begins.
The greater sage-grouse are probably best known, by most, for their extravagant courtship rituals.

Around the beginning of March, the male grouse return to their communal mating grounds called a lek where they compete with other males to attract and breed with the females. The ritual is called lekking. The lek is in an open area where visibility is good – such as a dry lakebed.

To show their dominance, the males raise their tail feathers in a magnificent fan, fill their breast sacs with air then thrust the air out of the sacs making a popping/bubbling sound as they strut around the lek in a regal fashion.

The females are attracted to the leks by the calls of the males, which can carry for over 1.5 miles. When they arrive, they roost among the males to watch their strutting performances. The hens may visit the lek several times during the breeding season before nesting.

During the courtship rituals, the females will begin searching for a nesting site. Most will choose to build their nests under the protective cover of a sagebrush bush. The female lines the bowl-shaped nest with dead grass and a few feathers. When she sits on her nest of 6-8 eggs, her camouflage colors go to work and make her nearly invisible from her surroundings. A potential predator may often pass by her as she sits motionless and in silence on her nest for a 30-day incubation period.

Dr. Terry Messmer, Utah State University Extension wildlife specialist and director of the Berryman Institute explains, “Greater sage-grouse do not have a muscular crop and are not able to digest hard seeds like other upland game species such as the ring-necked pheasant… they depend on sagebrush for their survival. In fact, during the winter sage-grouse survive by only eating sagebrush. They are the only species that can gain weight during the winter by [consuming] sagebrush.”

Biologists estimate that since the European settlement of North America there has been a 50% decline of the sage-grouse sagebrush habitat and population.

In the late 1990’s, in an effort to reverse this trend, Messmer through Utah State University entered into a collaboration with the State of Utah and numerous other stakeholders to develop a community-based conservation plan. Its purpose was to bring local communities, agencies, and researchers together to determine the best methods to preserve sage-grouse, their sagebrush habitats, and benefit the local community – without having to list it for protection under the federal Endangered Species Act.

After two decades of hard work, the partners have witnessed a resurgence of the greater sage-grouse as their habitats have been protected, enhanced and expanded.

If you’d like to see greater sage-grouse, the largest populations are found in western Box Elder County, on Blue and Diamond Mountains in Uintah County in northeastern Utah, in Rich County, and on Parker Mountain in south central Utah. Just remember to bring your binoculars.

Zane Gray’s “Riders of the Purple Sage” and Steve Tremble’s “Sage Brush Ocean” are book titles that may invoke excitement from your literary past. Or you may be traveling along the interstates and side roads of our great state as monotony sets in and drowsiness tightens your grip on the wheel while you nod your way through endless miles of this seemingly drab landscape.

In science jargon it’s referred to as sage steppe, the dominant landscape throughout much of Utah and the Great Basin. Much of this maligned biotic community has been degraded or lost through various mismanagement practices. Sage Steppe is considered an endangered ecosystem despite the seemingly large area it inhabits, primarily due to fragmentation. And the iconic Gunnison sage grouse has followed its demise having recently been placed on the threatened species list.
I just returned from spending a day of study in the field with 16 college students running transects for the Grand Teton N.P. The park is spending millions in sage steppe restoration work to reclaim this critical plant community.

Sagebrush is an important member of an ecosystem that helps support many birds, reptiles, amphibians, and mammals, as well as an abundance of insects and microbes. One study found nearly 300 arthropod species directly living on just a few plants including- 72 spider, 237 insect, 42 of which were gall-forming, amongst many other species. Such diversity also indicates that sage is playing an important part in maintaining the health of the environment providing ecosystem services such as soil protection, water conservation and nutrient cycling.
Sage is well adapted to the demands of semi-arid deserts. It has tap roots that can go over 15 feet deep to suck up any ground water that might exist and forms extensive webs of surface roots in association with symbiotic fungal hyphae to efficiently gather any rain that might fall. Oftentimes, sagebrush grows in clonal communities with members that can live over 100 years!

Aromatic odors emanating from sage, especially following a downpour of rain, comes from a mix of chemicals including camphor, terpenoids, and a cocktail of other volatile compounds. Some of the chemicals have anti-herbivory action by killing the gut bacteria of carious browsers although pronghorn antelope seem to have evolved resistance to these toxins. Other browsers like cattle, sheep, and mule deer can only eat sagebrush in small doses or whan the leaves are young and tender.

It is this mixture of molecules that sagebrush produces which come into play for communication. Sagebrush is eaten by many mammals and insects. When sagebrush is browsed on by a pronghorn or grasshopper volatile compounds are released from the wound that warn other branches of the same sagebrush as well as the neighboring sage about the potential threat. The sagebrush in the area react to the warning by metabolizing toxins that make them taste unappealing and that cause digestive discomfort for future herbivores who try to make a meal of them.

Native Americans considered sage a sacred plant. It offered medicine, clothing, shelter, and was commonly used in their ceremonial sweat lodges. Last but not least, my lovely granddaughter was given the name Sage. So the next time you find yourself surrounded by our “sagebrush ocean” pay tribute to this vibrant and intricate community of life.
