Bear-human conflict risks pinpointed amid resurgent bear population



by Mongabay.com on 5 November 2018

New research maps out the potential risk “hotspots” for black bear-human conflict based on an analysis of conditions that led to nearly 400 bear deaths between 1997 and 2013.

The study area covered the Lake Tahoe Basin and the Great Basin Desert in western Nevada.

The methods used to predict risks based on environmental variables could help wildlife managers identify and mitigate human-carnivore conflict in other parts of the world, the authors write.

Scientists have mapped out instances of human-black bear conflict in a part of the U.S. state of Nevada where bears are returning decades after they vanished.

The results of their analyses, reported in the October issue of the journal Global Ecology and Conservation, could help wildlife managers identify specific sites where this type of conflict is more likely in the future, potentially allowing them to avert the deaths of black bears as a result.
“Ultimately the goal of conservation is to have more individuals of species like bears and other carnivores on landscapes like we have accomplished in the Great Basin, but we then have to understand how to limit their mortality that results from conflicts with humans,” conservation scientist and study co-author Jon Beckmann, who directs the Wildlife Conservation Society’s Rocky Mountain West program, said in a statement.

Nevada Pushed To Tighten Wild Reptile Collection Rules – via Herp Digest


 The Nevada Independent by Daniel Rothberg, 8/27/17  
  
Explore Nevada’s wild reptile removal restrictions, and you’ll find some oddities.

Collectors can remove reptiles with their hands, but they can’t use explosives. They’re allowed to use tongs but they can’t use a jackhammer. They can use a noose or a snake hook or nets, but they can’t use a crowbar or a tire iron or cans or man-made pits that could disrupt the desolate terrain of the Mojave and Great Basin deserts.

Commercial collectors can remove an unlimited number of chuckwallas but they must submit monthly logs of the species, sex and age of their catch. They’re required to pay a $250 annual fee, must be a Nevada resident and keep a transaction history of all sales, trades or barters.

With these conditions, all listed in the state’s administrative code, the Nevada Board of Wildlife Commissioners has issued a couple dozen permits to reptile collectors since the commissioners made the practice legal in 1986. Licenses peaked at 31 in 1994, when registered collectors took more than 31,000 reptiles, a number that has steadily decreased since then. About 7,000 reptiles were removed last year, and now there are seven collectors registered with the state, five of whom belong to the same family.

Regulators at the Nevada Department of Wildlife have been concerned about commercial collection, which is banned in bordering states. And after two past attempts, the department is renewing a push to restrict the practice, citing concerns about population loss and the possible use of illegal traps. 

The department is currently drafting two regulations, one that would prohibit all commercial reptile collection and another that would limit collections by criteria, such as season or species. Wildlife commissioners, who set policy, are expected to consider the proposals in September.

At a wildlife commission meeting in August, collectors defended their methods as legal and argued that their business did not threaten what they see as an abundant reptile population.

But the department sees commercial collection as one of many threats facing the roughly 50 reptile species in Nevada, said Jason Jones, an NDOW biologist pushing for the regulations. Other threats to population size include climate change, development and disease.

“It’s death by one-thousand cuts,” he said.

About 4.7 million U.S. households owned one or more reptiles in 2010, but they often buy pets from captive breeders, according to a 2011 report prepared for the U.S. Association of Reptile Keepers, a non-profit focused on responsible reptile ownership. This trend is not limited to the U.S. A 2014 analysis in the British Herpetological Society’s journal found that 90 percent of U.S. reptile and amphibian exports — shipped to countries in Europe or Asia — were captive bred.

For months, Jones has been presenting this data at wildlife commission meetings to provide regulators with context for where Nevada fits into the U.S. reptile trade, which brings in about $1.4 billion in annual revenue, according to estimates from the Association of Reptile Keepers.

Based on collection logs, he estimated that wild-caught Nevada reptiles (excluding turtles, which can’t be exported from Nevada), accounted for 12 percent of U.S. exports from 2005-2010. And Jones suggested that this trade can be lucrative, with gopher snakes going for $380 in Europe.

Jeremy Bentz, one of the remaining collectors in Nevada, said he was “laughing on the inside” when he heard that claim repeated back. “It’s not a whole big money-making thing,” he said.

He said he collects reptiles on the side for a few months out of each year, usually in April and May. His father collects reptiles full-time and his uncle uses it as one source of income, Bentz said. “I do it as a family thing,” he said during an interview. “It pays for my camping trip.”

The family has tangled with the department over commercial collection before. In 1989, the family, with other collectors, sued the department after its first attempt to prohibit commercial reptile collection. That case was ultimately appealed to the Supreme Court, which ruled in favor of the department. Despite winning the case, the commission backed down from the ban (the commission considered a ban again in 1998 but ultimately allowed the practice to continue).

In its ruling, the Nevada Supreme Court said that it was within the commission’s power to issue the ban — that the burden fell on the collectors to prove that the practice did not harm wildlife.

That claim is at the center of the department’s argument.

At recent commission meetings, Jones has argued that commercial collection poses an issue because it often overlaps with breeding months, and populations are slow to recover. Looking at collection logs, he showed the commission that in the Amargosa and Ivanpah valleys, collectors have, at times, come back with fewer reptiles per day, despite devoting more time to collection.

“Even with an increased effort, they had a very little return,” Jones said at the July meeting.

Jeremy Buntz said the department’s presentation was misrepresentative of what he observed on the ground. He questioned how the department defined effort, especially with a small sample size of collectors who work at different paces and are not all collecting to generate income.

Jones conceded that the commercial collection data is not perfect.

“It’s market driven,” Jones said. “But it raises a lot of red flags.”

Other environmental groups have joined the department’s push.

Patrick Donnelly, who runs the Center for Biological Diversity’s regional office in Las Vegas, argued collection can have “huge, cascading effects on overall (reptile) population numbers.”

Donnelly said it’s especially concerning that the the practice continues on public land managed by the BLM. A prohibition, he said, would bring “Nevada in line with the rest of the West.”

He added that the commission, a nine-member panel appointed by the governor and charged with protecting the state’s wildlife, could be “legally liable” if it doesn’t act on the reptile issue.

Then there are questions of legality.

According to the department, there are more than 700 pitfall traps in Southern Nevada. Pitfall traps, used for collecting insects or in controlled ecological studies, are an illegal method for capturing reptiles. The traps comprise small holes in the ground that blend with the desert. The department has documented reptiles, mice and scorpions falling into these traps.

Of the traps it checked in 2016 and 2017, it found that about half of all reptiles and nearly all mammals that fell into the traps had died. These traps are not permitted, the department said, and a number of them are maintained by reptile collectors. In recent months, nearly 300 have been removed by volunteers and solar developers, but they remain a concern for regulators.

“There is significant mortality of reptiles due to large numbers (700+) of unpermitted pitfall traps,” one NDOW administrator wrote in a memo ahead of the July commission meeting.

The collectors said they used traps to catch unregulated scorpions, a practice that is legal.

Doug Nielsen, a spokesman for NDOW, said there are ongoing investigations.

New U.S. Toad Species Discovered for First Time in 50 Years-Nevada's Dixie Valley Toad Already Threatened With Extinction – via Herp Digest





Press Release 7/6/17- Reno, Nev. — Researchers at the University of Nevada, Reno and Paul Smith‘s College published a paper today in the journal Zootaxa describing the Dixie Valley toad as a new species in the Great Basin of northern Nevada.

While introducing this new species, the paper also highlights the authors’ concerns for the toad’s conservation: The animal’s survival is urgently threatened by proposed development of a geothermal energy facility in its range.

“I’m excited to hear about the discovery of this new toad, as it increases our knowledge about the vast diversity of amphibians that we have in this country,” said Jenny Loda, a Center attorney and scientist focused on protecting amphibians and reptiles. “But at the same time, I’m concerned for its survival. I hope it was discovered in time to save it from the threats it faces.”

The Dixie Valley toad is found in remote wetlands fed by thermal desert springs on the western edge of the Dixie Valley Playa in Churchill County. Its range is restricted to less than 1,500 acres, making it especially vulnerable to impacts to its habitat. Like many of Nevada’s groundwater-dependent species, it relies on consistent spring flow for survival. This little toad has large, prominent eyes and an olive-colored body dotted with black freckles and rust-colored warts bordered by black halos.

The Bureau of Land Management is currently reviewing the proposed Dixie Meadows Geothermal Utilization Project, which would hurt the toads by constructing facilities and infrastructure on or near their habitat. This project would pump almost 46,000 acre-feet of water per year from the natural underground geothermal reservoir, altering groundwater flow patterns and potentially draining the toad’s wetland habitat.

“We hope the BLM will recognize the importance of this new toad and go back to the drawing board on its review of the Dixie Meadows Geothermal Project,” said Loda. “It’s horrible to think that we may lose this new species just as we’re beginning to learn about it.”

The Center is working to protect the Dixie Valley toad through participation in the environmental review process for the proposed geothermal project and will submit a petition to U.S. Fish and Wildlife to protect the toad under the Endangered Species Act.

Three men face charges for killing tiny, endangered fish in drunken rampage

 Devils Hole pupfish, of which there are fewer than 115 in existence, found dead after men were seen entering fenced-off area of national park

Friday 13 May 201620.19 BST Last modified on Saturday 14 May 201603.41 BST

Three men have been arrested over a drunken rampage that resulted in the death of a member of one of the rarest fish species in the world.

The three suspects have been charged by police after allegedly breaking into a fenced-off protected area of Death Valley National Park in Nevada on 30 April. The men stomped around in the water of Devils Hole, strewing vomit, beer cans and boxer shorts over the area, and tearing up the habitat of the Devils Hole pupfish, one of the rarest fish in the world. One of the fish was later found dead.

According to the National Parks Service, the men fired a gun at least 10 times at gate locks, a motion sensor and several signs. Sensitive scientific monitoring equipment was also damaged. Three beer cans were left behind, as well as the vomit of one of the men and the boxer shorts of another.

The Nye County sheriff’s office said it has charged Steven Schwinkendorf, 29, Edgar Reyes, 35, and Trenton Sargent, 26, with the killing of an endangered species, destruction of property, trespassing and unlawful possession of a firearm. They face the possibility of fines of up to $50,000 and a year in prison.

“Their unlawful visit ultimately culminated with at least one of the suspects stripping off their clothes and entering the water of Devils Hole,” the sheriff’s office said in a statement.

“The suspect(s) in the water stomped around the shelf area of the critical ecosystem before swimming around the deeper water, leaving behind a pair of dirty underwear when finished.

“The intrusion is believed to have resulted in the death of at least one endangered Devils Hole pupfish, and fisheries biologists are trying to ascertain the extended damage that may have been done to food sources and egg sites which could lead to more loss of a species whose numbers are now below the last count of 115 in existence.”

Is the Huge Handprint Found in Nevada’s Lovelock Cave Evidence of a Lost Race of Cannibalistic Giants?

Did two Bigfoot hunters stumble onto evidence of a long lost race of giant cannibals in a Nevada cave? They believe that their discovery of a huge, charred handprint backs up their claims of legendary “Red-Headed Giants”.

In 1911 David Pugh and James Hart, two guano miners (yes, mining bat poo is really a thing) were excavating a cave on the eastern side of Nevada when they found something intriguing buried under 250 tons of excrement.

According to the men’s bizarre tale, hidden beneath six feet of bat crap they discovered several sets of giant bones, remains which many now believe belong to the Si-Te-Cah, a storied Paiute tribe of red-haired cannibal giants. Legend has it that the last remaining giants were burned alive inside the cave thousands of years ago.

As if being torched alive and having your race wiped out wasn’t bad enough for Si-Te-Cah, it seemed that Pugh and Hart were more interested in harvesting guano than preserving history, and many artifacts were destroyed before the Museum of Anthropology and the University of California were finally contacted for a proper excavation. Eventually, in 1984, Lovelock Cave was designated as a historical site and given all the protections that come with the title.

Bear historical ranges revisited: Documenting the increase of a once-extirpated population in Nevada†

Article first published online: 26 MAR 2013 

DOI: 10.1002/jwmg.548 


Abstract 

Black bears (Ursus americanus) were once abundant in Nevada and distributed throughout the state, yet recognition of the species' historical occurrence in the state is uncommon and has therefore been ignored in published distribution maps for North America. The lack of representation on distribution maps is likely due to the lack of any scientific data or research on bears in Nevada until 1987. Historical records dating back to the 1840s compiled by Nevada Department of Wildlife (NDOW) biologist Robert McQuivey indicate presence of black bears throughout the state in the 1800s through about 1930. The paucity of historical references after 1931 suggest extirpation of black bears from Nevada's interior mountain ranges by this time. We report on historical records of black bears in the state of Nevada and the results of a current population estimate of black bears derived from a sample of marked bears (n = 420) captured 707 times between 1997 and 2008. Using Pradel and Cormack–Jolly–Seber models in Program MARK, we estimated overall population size, finite rate of growth (λ = 1.16), quarterly and annual survival rates for males and females, seasonal capture probabilities, and recruitment rates. Our results indicate an overall population size of 262 ± 31 adult black bears in western Nevada. These results suggest that the once abundant, then extirpated population of black bears in Nevada is increasing at an annual average rate of 16%. Although the current distribution is limited to the western part of the state, our findings suggest possible expansion of the population into historical habitat within the interior and eastern portions of the state that have been absent of bears for >80 years. Finally, based on historical records, we present suggested revised historical distribution maps for black bears that include the Great Basin ranges in Nevada. © 2013 The Wildlife Society.

Black Bears On the Rebound in Nevada


Mar. 29, 2013 — A new study from the Wildlife Conservation Society (WCS) and the Nevada Department of Wildlife (NDOW) has pieced together the last 150 years of history for one of the state's most interesting denizens: the black bear.

The study, which looked at everything from historic newspaper articles to more recent scientific studies, indicates that black bears in Nevada were once distributed throughout the state but subsequently vanished in the early 1900s. Today, the bear population is increasing and rapidly reoccupying its former range due in part to the conservation and management efforts of NDOW and WCS.

Compelled in part by dramatic increases in human/bear conflicts and a 17-fold increase in bear mortalities due to collisions with vehicles reported between the early 1990s and mid- 2000s, WCS and NDOW began a 15-year study of black bears in Nevada that included a review of the animal's little-known history in the state.

Over the course of the study, black bears were captured both in the wild and at the urban interface in response to conflict complaints. The captured animals used in the study (adult males and females only) were evaluated for multiple physiological indicators including condition, sex, reproductive status, weight, and age, prior to being released. From the information gathered, the population size in the study area was estimated to be 262 bears (171 males, 91 females).

Confirmed sightings and points of capture from 1988 to present were mapped and presented in the report to illustrate current population demographics, and will be used to inform bear management in Nevada.

"It's critical to understand the population dynamics in a given area in order to make informed decisions regarding management," said WCS Conservation Scientist Jon Beckmann. "This includes decisions on everything from setting harvest limits to habitat management to conservation planning in areas where people will accept occupation by bears. We used this long-term study to determine if reported incidents were due to an increasing or expanding bear population, or people moving to where bears are located. The answer is both."

The study area extended from the Carson Range of the Sierra Nevada eastward to the Virginia Range and Pine Nut Mountains, and from Reno south to Topaz Lake -- an area collectively referred to as the Carson front. Because many captures were in response to conflicts, the urban interfaces of cities and towns of the Lake Tahoe Basin were included.

Researchers Find First Evidence of Ice Age Wolves in Nevada


Dec. 13, 2012 — A University of Nevada, Las Vegas research team recently unearthed fossil remains from an extinct wolf species in a wash northwest of Las Vegas, revealing the first evidence that the Ice Age mammal once lived in Nevada.

The metapodial, or foot bone, was uncovered late last year by UNLV geologist Josh Bonde during a survey of the Upper Las Vegas Wash. They have now confirmed that the bone comes from a dire wolf.

The discovery site is near the proposed Tule Springs Fossil Beds National Monument, a fossil-rich area known for its diversity and abundance of Ice Age animal remains. Scientists estimate the fossil to be 10,000 to 15,000 years old during the Late Pleistocene period.

"Dire wolves are known to have lived in almost all of North America south of Canada, but their historical presence in Nevada has been absent until now," said Bonde, a UNLV geology professor. He was a Ph.D. student at the university when he discovered the bone.

"The Tule Springs area has turned up many species, but it's exciting to fill in another part of the map for this animal and reveal a bit more about the Ice Age ecosystem in Southern Nevada."

Go West, Young Lion: New Study Shows Mountain Lions Dispersing from Nevada to California


ScienceDaily (Oct. 5, 2012) — Using data collected over the course of seven years, the study looked at DNA in tissue samples collected from 739 mountain lions. In the first-of-its-kind study at this scale, the authors used only the gathered genetic information to discover population structures and history, and to identify what areas in the region serve as "sinks" (habitat that animals move to at a greater rate than they disperse from) and "sources" (areas that animals disperse from at a greater rate to live elsewhere).
The study, "Identification of Source-Sink Dynamics in Mountain Lions of the Great Basin" appears online in August's early-view edition of the journal Molecular Ecology. Authors of the study include: Alyson M. Andreasen of the University of Nevada; Jon P. Beckmann of WCS; and Matthew L. Forester, William S. Longland, and Kelley M. Stewart of the University of Nevada.

'Haunted Highway': Searching For Hellhounds In Nevada (VIDEO)


The latest episode of "Haunted Highway" (Tue., 10 p.m. ET on Syfy) found Jack Osbourne and Dana Workman in Nevada.

The pair was hoping to pick up the scent of those monsters most feared by"Supernatural's" Sam and Dean Winchester: hellhounds.

The hounds are supposedly the spirits of vicious dogs that were once abused by miners in the area.

As Workman walked through the undergrowth, they both heard a growl. Then, through his thermal camera, Osbourne spotted some kind of four-legged creature moving toward her.

Badger Dodges Tranquilizer Dart, Prompts Standoff In Nevada Store


SPARKS, Nev. -- A badger that wandered into a retail store in northern Nevada dodged a tranquilizer dart and held authorities at bay for about an hour before the teeth-baring critter was lured into a cage with cat food.
No one was hurt in the standoff at the bottled water/convenience store in a residential neighborhood in Sparks, and the badger ultimately was returned to the wild north of Reno, Nevada Department of Wildlife spokesman Chris Healy said Wednesday.
"Apparently the door was open a bit and this badger just walked in," Healy told The Associated Press.
"Obviously it was pretty hungry because when they put the cat food in the trap, it went right in," he said.
A state game warden was called to the Fresca Waterstore on Rock Boulevard near Sparks High School about 3 p.m. on Tuesday along with two assisting officers from Washoe County Animal Services, Healy said.
NDOW photos show the badger baring its teeth through the store's glass door and later at an animal control officer trying to nab it with a noose on a stick inside the store. The baited cage was brought in after the tranquilizer dart missed.

Small bird, big stakes: With sage grouse being considered for protected status, some wonder what economic fallout could be for Nevada

Protecting a chicken-sized bird with an uncertain future could come with a cost to Nevada as big as the state’s sea of sagebrush.

With a deadline nearing for the federal government to decide whether the sage grouse should be listed under the Endangered Species Act, officials from state and federal agencies, ranchers and energy developers are mobilizing in an effort to keep that from happening. Environmentalists who petitioned to list the bird are watching closely, with everyone involved acknowledging a legal battle is likely whatever is ultimately decided.

At risk could be Nevada’s ranching, mining and agricultural industries as well as long-touted goals to attract renewable energy development — and the jobs that come with it — to the Silver State.

Some say the stakes couldn’t be higher.

“If it’s listed, it will be the next spotted owl,” J.J. Goicoechea, a Eureka rancher and president of the Nevada Cattlemen’s Association, said in comparing the sage grouse to the bird that had a widespread impact on the economy of the Pacific Northwest after its listing in 1990.

Man-eating giants discovered in Nevada

A Paiute brave faces the maurading giants
The Paiutes, a Native-American tribe indigenous to parts of Nevada, Utah and Arizona, told early white settlers about their ancestors' battles with a ferocious race of white, red-haired giants. According to the Paiutes, the giants were already living in the area.

Roaming, man-eating giants
The Paiutes named the giants Si-Te-Cah that literally means “tule-eaters.” The tule is a fibrous water plant the giants wove into rafts to escape the Paiutes continuous attacks. They used the rafts to navigate across what remained of Lake Lahontan.

According to the Paiutes, the red-haired giants stood as tall as 12-feet and were a vicious, unapproachable people that killed and ate captured Paiutes as food.

Giants roamed the Earth
The legend
The Paiutes told the early settlers that after many years of warfare, all the tribes in the area finally joined together to rid themselves of the giants.

One day as they chased down the few remaining red-haired enemy, the fleeing giants took refuge in a cave. The tribal warriors demanded their enemy come out and fight, but the giants steadfastly refused to leave their sanctuary.

Frustrated at not defeating their enemy with honor, the tribal chiefs had warriors fill the entrance to the cavern with brush and then set it on fire in a bid to force the giants out of the cave.

The few that did emerge were instantly slain with volleys of arrows. The giants that remained inside the cavern were asphyxiated.

Later, an earthquake rocked the region and the cave entrance collapsed leaving only enough room for bats to enter it and make it their home.

Cave of the Nevadan man-eating giants
The find
Hundreds of years later archaeologists explored the cavern near Lovelock, Nevada--the cave the Indians had described.

What the scientific researchers found was staggering: over 10,000 artifacts were unearthed including the mummified remains of two red-haired giants—one, a female 6.5-feet tall, the other male, over 8-feet tall.

Many of the artifacts (but not the giants) can be viewed at the small natural history museum located in Winnemucca, Nevada.A giant red-haired mummy from Nevada

Confirmation of the myth
As the excavation of the cave progressed, the archaeologists came to the inescapable conclusion that the Paiutes myth was no myth; it was true.

What led them to this realization was the discovery of many broken arrows that had been shot into the cave and a dark layer of burned material under sections of the overlaying guano.

Among the thousands of artifacts recovered from this site of an unknown people is what some scientists are convinced is a calendar: a donut-shaped stone with exactly 365 notches carved along its outside rim and 52 corresponding notches along the inside.

But that was not to be the final chapter of red-haired giants in Nevada.

In February and June of 1931, two very large skeletons were found in the Humboldt dry lake bed near Lovelock, Nevada.
