<\/div>\n

In the late 1980s, conservation biologist Jessica Young was an undergraduate researching the sage grouse in the Sierra Nevada when one of her professors handed her a cassette tape. He said there was a guy out in Gunnison who claimed that the grouse there sounded different. Young listened to the recording of grouse calls and decided she had to see the birds for herself.<\/p>\n

Young began working with Clait Braun, a researcher at Colorado Parks and Wildlife (then called the Department of Wildlife) who had discovered as early as 1977 that the Gunnison sage grouse was different from its cousin, the wider-ranging greater sage grouse.<\/p>\n

The work of Young, Braun and other scientists eventually helped prove that the Gunnison sage grouse was a separate species of ground-nesting bird, one that was officially declared a new species in 2000.<\/p>\n

But there was a problem.<\/p>\n

Researchers quickly realized that not only was this grouse a new species, it also was in serious trouble. By the time they discovered that this bird \u2014 which is perfectly adapted to western Colorado\u2019s high-desert sagebrush ecosystem and famous for its elaborate spring mating dance \u2014 was a distinctive, smaller species, the bird was already on the verge of vanishing.<\/p>\n

\u201cIt was clear to me by the mid-1990s that this was about much more than the Gunnison sage grouse,\u201d Young said. \u201cI remember thinking that it was probably going to be the 21st-century test of how my nation valued both biodiversity and the economic well-being of communities across the West. I believe that is what the Gunnison sage grouse really represents.\u201d<\/p>\n

Target numbers too low?<\/p>\n

After years of conservation efforts in the Gunnison basin and elsewhere, the bird\u2019s numbers are still declining. In 2014, in a controversial move that sparked lawsuits from the state of Colorado, Gunnison County and the Gunnison County Stockgrowers Association, the U.S. Fish and Wildlife Service listed the bird as \u201cthreatened\u201d under the Endangered Species Act. Five years later, it remains unclear what effect the listing has had on the bird.<\/p>\n

This past fall, the FWS released its draft recovery plan for the species, which is open for public comment through Tuesday. The plan lays out target-population numbers that must be met for seven out of nine years before the species could be considered on the road to recovery and potentially delisted. The plan also charts conservation projects and actions for the next 50 years, at an estimated cost of more than $560 million. The final recovery plan is scheduled to be completed by Nov. 1.<\/p>\n

But environmental groups \u2014 along with Braun and Young, two scientists who have dedicated much of their careers to studying the bird \u2014 say these population targets are too low to ensure recovery of the species. The target number for the Gunnison basin is 748; in 2019, researchers counted nearly 400 fewer than this.<\/p>\n

\u201cHow are they going to get to 748? They are hoping that population is going to bounce back. It\u2019s not likely to do that,\u201d Braun said. \u201cWe are dealing with a population size of 2,500 birds, the total population everywhere. \u2026 It\u2019s really grim. Really, really grim.\u201d<\/p>\n

Declining populations<\/p>\n

Gunnison sage grouse numbers have indeed declined \u2014 some say alarmingly so \u2014 in recent years.<\/p>\n

Over the past several years, the three-year average high male count \u2014 the highest number of male birds that the researchers spot \u2014 has dropped across all populations. In the Gunnison basin, the 2019 number was 583, down from 772 in 2018, 886 in 2017 and 905 in 2016.<\/p>\n

2019 posted the lowest bird numbers since the count methodology was standardized in 1996. The high male count for the Dove Creek population in western Dolores County dipped to zero, while high male counts at Cerro Summit and Poncha Pass in Colorado and the area near Monticello hovered from just three to seven birds.<\/p>\n

\u201cYou don\u2019t want to see declines like this when you have seven birds,\u201d said Kathy Griffin, grouse conservation coordinator for CPW. \u201cTo say we are not concerned would not be true. \u2026 We have seen these kinds of declines before, but we are getting to the lowest we\u2019ve ever been.\u201d<\/p>\n

According to a paper by Braun, Young and others, the Gunnison sage grouse once roamed throughout most of southwestern Colorado. It disappeared from Pitkin County in the 1960s. In the 1990s, it was extirpated in Eagle and Garfield counties.<\/p>\n

The largest populations of the Gunnison sage grouse \u2014 and around 85% of the bird\u2019s remaining total population \u2014 live in the Gunnison basin. Smaller populations of the species, referred to as satellite populations, are scattered throughout western Colorado (Cerro Summit, Crawford, Dove Creek, Pinon Mesa, Poncha Pass and western San Miguel County) and eastern Utah (Monticello).<\/p>\n

The 2014 \u201cthreatened\u201d listing was based mostly on these shrinking satellite populations, which scientists think need to remain robust as an insurance policy should some kind of environmental-related disaster or disease befall the main population of birds in the Gunnison basin.<\/p>\n

Those who opposed federal involvement, including Gunnison County, still feel the sting of the 2014 listing as an affront to the collaborative conservation work of local groups, including the county-led Gunnison Sage Grouse Strategic Committee. Committee Chair and Gunnison County Commissioner Jonathan Houck said the recovery plan, much like the listing itself, still focuses too much on the satellite populations. The Gunnison basin, Houck said, is doing its part to help the bird.<\/p>\n

\u201cThe draft recovery plan correctly recognizes the high resiliency of the Gunnison sage grouse population in the Gunnison basin and also recognizes correctly the strength of the habitat protection in the Gunnison basin,\u201d Houck said. \u201cThe irony to me is this is the entire argument we made before the listing.\u201d<\/p>\n

Bird counts<\/p>\n

CPW uses something called \u201cHigh Male Count\u201d to track bird numbers year over year. Each spring, biologists watch from the sidelines as regal-looking male Gunnison sage grouse perform their courtship ritual \u2014 strutting and bobbing, fanning their banded tail feathers and popping their air sacs in an effort to attract a female \u2014 on leks, which are open areas ringed by sagebrush that the birds return to year after year.<\/p>\n

Researchers count each male they see on several trips to the leks they make each season, meaning the same bird can be counted more than once. These numbers are then averaged over three years to smooth out the seven-to-12-year fluctuations associated with grouse population and used to estimate the total population size.<\/p>\n

The one-two punch of 2018\u2019s extreme drought, which may have resulted in bird deaths, and 2019\u2019s deep snow may have contributed to this year\u2019s low counts. Counting is a logistical challenge because of the precise method used. CPW biologists were not able to access all of the leks last spring because of lingering deep snow, and in other areas, counters heard the birds\u2019 signature popping noise but didn\u2019t catch sight of them.<\/p>\n

\u201cWe had a horrible year of counting,\u201d Griffin said. \u201cBecause we could never see them, we had to put down a zero even though we knew there were birds there.\u201d<\/p>\n

Whatever the reason for the low counts, bird populations will need to increase in order for the FWS to consider the species recovered and to potentially delist it. The recovery plan sets a target three-year average high male count in the Gunnison basin of 748 for seven out of nine years for the population to be considered stable.<\/p>\n

The sagebrush sea<\/p>\n

Braun and others, including environmental group Rocky Mountain Wild, also say the draft recovery plan lacks specificity when it comes to how to conserve the bird\u2019s habitat \u2014 the silvery-green expanse known as the sagebrush sea.<\/p>\n

Western Colorado\u2019s sagebrush sea is naturally fragmented by canyons and mountains. But in recent decades, prime habitat also has been bisected by roads and trails, interrupted by residential developments, affected by cattle grazing, and encroached upon by pinon and juniper trees. The Bureau of Land Management manages about 42% of Gunnison sage grouse habitat.<\/p>\n

\u201cI think the really key thing is that there needs to be habitat that is set aside from development and other threats on public land, and that isn\u2019t really the case right now,\u201d said Megan Mueller, a senior conservation biologist at Rocky Mountain Wild.<\/p>\n

Although some private landowners in the Gunnison basin have participated in habitat restoration projects such as restoring wet meadows and putting conservation easements on their property to protect it from future development, Braun says those measures are not enough. He thinks a more drastic action is needed: stopping livestock from grazing on public land in Gunnison sage grouse habitat until populations of the bird increase.<\/p>\n

\u201cGrazing is a key factor in why sage-grouse populations are down in the Gunnison basin,\u201d Braun said. \u201cUntil we get a handle on the livestock grazing, nothing is going to really improve.\u201d<\/p>\n

Braun recognizes that his idea to temporarily outlaw grazing on public land in Gunnison sage grouse habitat is an idea many will find unpalatable, even radical. Ranching is an important part of the culture of rural western Colorado.<\/p>\n

\u201cWe want to keep ranching active in the Gunnison Valley,\u201d Houck said. \u201cIt\u2019s the thing that\u2019s defined this place.\u201d<\/p>\n

One challenge to habitat conservation, Young said, is that the sagebrush sea has long been an undervalued ecosystem. It has traditionally been a place with few regulations, where mountain biking and hiking trails snake through the landscape, where people put dumps and mine tailings, where driving off-road was \u2014 and sometimes still is \u2014 common and where overgrazing damaged the landscape.<\/p>\n

Saving the Gunnison sage grouse, Young said, will require reexamining the economic, social and ecological values that people hold about this landscape. Although the federal involvement may have polarized some groups, the little ground-nesting bird also has the potential to bring together disparate factions to work toward the same goal: species conservation.<\/p>\n

\u201cI think, in the 2000s, the Gunnison sage grouse are asking us again to consider what our values are for both biodiversity and community success during a time of climate change,\u201d Young said. \u201cThey are going to be an indication of how we come together and demonstrate our values and resilience.\u201d<\/p>\n
