3 endangered species in Utah and how state partnerships are helping them
SALT LAKE CITY — Friday, May 17 is Endangered Species Day. Several events will be held throughout Utah, making it a great opportunity to learn about some local endangered and threatened species and what the Utah Division of Wildlife Resources and other agencies are doing to help them.
An endangered species is any species that is at serious risk of extinction in a specific area or throughout all of its natural habitat. A threatened species is any species that is likely to become an endangered species in the foreseeable future throughout much or all of its habitat. A species is classified as sensitive if it is likely to undergo substantial population declines in all or part of its natural region without management intervention.
The U.S. Fish and Wildlife Service makes the determination for adding a species to the threatened and endangered species list. State wildlife boards make the determination for adding a species to the sensitive species list.
There are currently 18 wildlife species in Utah listed on the federal endangered species list, with 10 listed as endangered and eight listed as threatened.
Of those, here are three success stories:
June suckers (endangered)
The June sucker is a fish species native to Utah Lake and the Provo River and is not found naturally anywhere else in the world. While it’s hard to pinpoint an exact cause for their decline, water flow alterations and drought, habit changes, and competition with and being preyed on by exotic fish species were all contributing factors. The June sucker population dropped to less than 1,000 fish, and they were placed on the endangered species list in 1986.
However, in 2002, the Utah Department of Natural Resources partnered with several agencies to work to restore their populations, and now there are tens of thousands of June suckers. Along with addressing water level issues at Utah Lake and its tributaries, the partnership also worked to establish a June sucker population at the DWR Fisheries Experiment Station in Logan. A special water-circulation facility is used there to quickly grow the fish in warmer water. Then once they are big enough, the fish are restocked into Utah Lake to help the population grow.
Involved in the massive effort was the Utah Reclamation Mitigation and Conservation Commission, Central Utah Water Conservancy District, Provo River Water Users Association, U.S. Bureau of Reclamation, U.S. Department of Interior, U.S. Fish and Wildlife Service and outdoor and recreational interest groups.
“It’s unfortunate that it takes so long to restore wildlife populations,” Chris Keleher, DNR director of recovery programs, said. “Once a species gets to the point that it’s endangered, it takes a huge effort and a lot of funding to get them back in shape. We’ve been fortunate to have partners who supported the effort, and we are getting there with the June sucker. Partnerships are the key to conservation effectiveness, and trust is the glue that holds partnerships together.”
With the threats to the June sucker being addressed through the partnership and with its population increasing in Utah Lake, it is hoped that this species will be considered for downlisting from endangered to threatened in the near future.
California condors (endangered)
California condors were first listed as endangered in 1967, with an estimated total population of 40-50 birds. By 1982, the population had dropped to only 23 birds. Condors are North America’s largest vultures, and due to their size, they require vast areas of wilderness where they have access to the carcasses of large animals.
The biggest factors in their population decline include the consumption of lead due to lead-based ammunition, eating trash and other litter, and changes in their habitat, like an increase in power lines and decrease in nesting areas due to land development.
Several organizations joined efforts to trap and remove the 22 remaining condors from the wild between 1982 and 1987. These birds were used to establish a captive breeding program to build up the condor numbers, and eventually led to re-established wild populations in California, Arizona, Utah and Mexico. Some condors are still kept in captivity in an effort to continue growing the population, and captive-born condors are released back into the wild each year.
“Condors are evolved to be long-lived in some of our harshest habitats,” DWR avian conservation program coordinator Russell Norvell said. “They survive with an efficiency that’s the opposite of ‘live fast, die young,’ an efficiency that’s successful in stable and predictable environments. The flip side is that recovery from such small numbers is hard when even the most experienced adults may successfully breed only once every several years.”
Nest sites are protected by agencies and the birds are hazed away from dangerous areas like power lines and wind turbines. Utah and Arizona are both working with hunters to reduce condor exposure to lead ammunition.
“Utah hunters have been very supportive of our lead ammunition reduction efforts,” DWR wildlife biologist Keith Day said. “They have readily and voluntarily joined in our voluntary non-lead ammunition program.”
As of December 2018, there was a total 488 California condors, with 166 in captivity and 312 in the wild, 88 of which are located in Utah and Arizona.
The organizations that partnered in the conservation efforts include DWR, The Peregrine Fund, the California Department of Fish and Wildlife, Arizona Game and Fish Department, the U.S. Fish and Wildlife Service, the Bureau of Land Management, the Ventana Wildlife Society, the U.S. Department of Agriculture and the U.S. Forest Service.
Mojave desert tortoise (threatened)
The Mojave desert tortoise, located north and west of the Colorado River in Arizona, Utah, Nevada and California, was listed as threatened in 1990. At the time, DWR was monitoring tortoise populations on two plots in southwest Utah. In 1986, biologists determined there was a significant decrease of tortoises on the Beaver Dam Slope, and there were only 8 to 16 tortoises per square mile in the area.
The biggest causes of the population declines were due to changes in their habitat as a result of urbanization.
“The same area where new homes are being built overlaps with areas where tortoises have shelters, forage sites and reproductive areas,” DWR wildlife biologist Ann McLuckie said. “In addition, getting preyed upon by predators and vehicle collisions or illegal removal has also attributed to declines in tortoise populations.”
The Red Cliffs Desert Reserve was created to protect the tortoise populations and their habitats from development. The DWR partnered with several organizations to restore habitats burned by wildfire and to construct fences along roadways near tortoise populations. Now, there are an estimated 15 to 25 desert tortoises per square mile, or roughly 2,250 total, throughout the Red Cliffs Desert Reserve, making their population densities much higher than other Mojave desert tortoise populations rangewide.
Desert tortoises require 13 to 20 years until they reach reproductive maturity, and they have low reproductive rates. Once they do reproduce, their offspring have high mortality rates from predators.
“Conservation work is critical to help recover the desert tortoise and protect vulnerable habitat,” McLuckie said. “By working with agency partners to actively protect habitat, tortoise populations can continue to recover across their range.”
Partners who have helped with desert tortoise conservation include DNR, the Bureau of Land Management, the U.S. Fish and Wildlife Service, Snow Canyon State Park, The Nature Conservancy, Washington County Water Conservancy, the University of Nevada-Las Vegas, and other local cities and conservation groups.
While people should never capture a desert tortoise found in the wild, there is an adoption program available for Utah residents who live outside of Kane, Iron and Washington counties. Click here for details about adopting a captive desert tortoise.
Where to learn more and get involved
People who want to learn more about some of Utah’s endangered species can attend one of several events happening this weekend.
DWR is partnering with the Living Planet Aquarium to celebrate Endangered Species Day. The event will be held Friday to Sunday at the aquarium. Visitors can talk with DWR biologists, see two desert tortoises and receive some educational handouts. There will also be a scavenger hunt, among other family activities. There is also a June sucker housed at the aquarium that people can see and learn more about.
Snow Canyon State Park is also hosting several events. The first one will be held Friday at 7 p.m. at the Snow Canyon visitor center, where McLuckie will give a presentation about desert reptiles. The second event will take place Saturday at 10 a.m., and participants will go on a hike with a biologist through the state park to see wild desert tortoises. Both events are free, but registration is required. People can contact Snow Canyon State Park for more information and to register.
Since 2001, DNR and other partnering agencies have helped prevent 20 species from being listed as endangered and threatened.
“Our species are indicators of the health of our ecosystems, and we need healthy ecosystems to provide those services that we depend on, like clean water and fresh air,” Keleher said. “All of that requires proactive investment in conservation.”

Boaters must stop at inspection stations to help prevent the spread of mussels
SALT LAKE CITY — What can cut your bare feet on a sandy beach and can also potentially cost taxpayers millions of dollars by getting into the wrong waterway? If you guessed quagga and zebra mussels, you’d be correct.
In order to prevent the spread of these invasive species throughout Utah, several of the annual mandatory inspection stations have opened for the busy summer season. There will be more inspection stations this year than in past years. The Utah Division of Wildlife Resources and Utah State Parks would like to remind boaters and anyone with a watercraft that they are required to stop at each of these inspection stations.
What counts as a “watercraft” and would require someone to stop?
Watercraft includes the following:
Motorboats and sailboats
Jet skis and wave runners
Canoes
Kayaks
Float tubes
Trailers and vehicles that go into the water on a boat ramp
Other personal watercraft
“Basically, if it floats, it’s a boat,” Scott Dalebout, the DWR statewide operations lieutenant, said. “Anyone transporting any watercraft is required to stop at these mandatory inspection stations. We have been tasked with doing everything possible to keep quagga mussels contained in Lake Powell (as well as other infested waters outside of Utah) and out of the rest of the waters in the state. These inspection stations are conducted to eradicate and prevent the infestation of these invasive species.”
Where are the inspection stations?
The mandatory inspection stations at Lake Powell and at the I-15 St. George point of entry are open year-round. All watercraft traveling north on I-15 must stop at the St. George station. Several other stations around the state are currently open for the summer boating season or will be open once fully staffed, including at Pineview Reservoir, Bear Lake, Utah Lake, Flaming Gorge and the state parks with waterbodies.
The station at the Daniels Canyon point of entry along U.S. 40 will be opening this weekend. Only vehicles that are traveling up the canyon with watercraft — southwest out of Heber City and Provo — need to stop. Vehicles with watercraft traveling the opposite way down the canyon — northwest toward Heber City — are not required to stop.
Mandatory inspection stations will be opening later — as staffing and access allow — at Fish Lake, Panguitch Lake and Joes Valley Reservoir. These stations will remain open during the boating season.
You can see a map of all the decontamination stations across the state here.
What happens at an inspection station?
When a boater stops at a mandatory inspection station, Aquatic Invasive Species professionals will check the watercraft for attached quagga and zebra mussels and for standing water. They also examine boats to ensure the drain plugs have been removed and have not been reinstalled. They will also get information about what waterbodies that watercraft has been on during the last 30 days.
What happens if someone transporting a watercraft doesn’t stop at the station?
State law mandates that all watercraft stop at an operating inspection station. Anyone who doesn’t stop is guilty of a class B misdemeanor. Along with receiving a citation, the individual will be directed back to the station to get their watercraft inspected. A watercraft can also be detained or quarantined if the owner refuses to submit to an inspection.
“Violations are addressed aggressively,” Dalebout said. “Even if you haven’t been out on the water yet, all watercraft need to stop.”
Administrative checkpoints
In addition to the inspection stations, DWR officials also conduct administrative checkpoints on various roadways throughout the year. These are different than mandatory inspection stations because all vehicles — not just those transporting watercraft — will be directed off the road. Then, the vehicles towing or hauling watercraft are directed to the operation areas for inspections.
These checkpoints are approved in advance by a magistrate and require law enforcement officers to be present.
“There are many reasons for how we’ve been able to contain quagga mussels to just Lake Powell,” Dalebout said. “Getting the necessary funding for the Aquatic Invasive Species program has been a huge component, as well as our partnerships with local water managers and other organizations. Our program includes these inspection stations, very dedicated staff educating the public about these invasive species and an aggressive law enforcement effort. The majority of boaters have also been very compliant and great to work with. Without public support, we can't succeed in this effort.”
