Wyoming Studies Mountain Goats

mtn goat wyomingThe Wyoming Game and Fish Department recently captured four mountain goats in the western part of the state as part of an on-going study into the animals’ travel between Idaho and Wyoming, says an Associate Press article in the Billings Gazette.

An article in the Caspar Star-Tribune adds that, “the goats were tranquilized while biologists collected nasal and tonsil swabs, blood and fecal samples.”

Mountain goats are not native to Wyoming, the articles state. But apparently, they are native to adjoining Idaho. After being reintroduced to Idaho, some of the mountain goats wandered over to Wyoming.

Non-native Lice Impact Cal. Deer Population

hair loss syndrome CDFWCalifornia Department of Fish and Wildlife (CDFW) researchers have captured and collected hair and blood samples from more than 600 deer and elk in an effort to understand “deer hair-loss syndrome,” says a CDFW news release.

A non-native louse appears to be a key factor in the syndrome, which also sometimes includes internal parasites. Deer with the syndrome are skinny, and the fawns don’t survive. A report from Fox 40 in Sacramento notes that the syndrome has been known in Oregon for years.

“Some of us speculate that the louse-infested deer spend so much time grooming they become easy targets of predation by coyotes or mountain lions,” said CDFW senior wildlife biologist, Greg Gerstenberg in the release.

The researchers have counted and identified lice on the captured deer, are following them through radio collars, and have treated some for lice. They hope to have answers soon.

Mule deer are in decline throughout the West, and California is no exception. This article from 2010 in the San Francisco Chronicle discusses the decline.

Invasive Ladybug Packs A Secret Weapon

Harmonia_axyridis01The multicolored Asian ladybug, also known as the harlequin lady beetle or ladybird (or just Harmonia axyridis), carries a fungal parasite in its blood that doesn’t seem to cause it much harm, but is deadly to the native ladybugs of Europe and North America.

That’s why the Asian ladybug has been such a ferocious competitor to native ladybugs, a paper in last week’s issue of the journal Science found. Scientists have long known that where Asian ladybugs are introduced, native ladybugs disappear, but they weren’t sure why. It seemed that the invasive species was out-competing the natives somehow. The new study explains why.

A fungus in the same genus infects honeybees.

More Black Bears in Oklahoma

FWC black bear cubAbout 200 people watched as the Oklahoma Department of Wildlife Conservation released a young black bear. The bear had been found and tranquilized in a university campus neighborhood and was released in a wildlife area, reported Tulsa’s News On Six.

The big turnout is a sign that black bears are not that common in Oklahoma. Black bears were reintroduced to Arkansas in the 1960s, the article says, and their populations there have grown so much that they are now moving into eastern Oklahoma.

The report also mentions a black bear survey being conducted by Cooperative Wildlife Research Unit at Oklahoma State University. Twenty bears have been trapped during the three years of the study, the report says.

NY Snapping Turtle Law Generates Buzz

Snapping_TurtleAll over the Internet, on Facebook, on blogs, on turtle forums and tortoise forums there are requests for New Yorkers to protest a proposed State Assembly bill that would allow trapping of snapping turtles.

I could not find any information on why these members of the New York State Assembly want to re-introduce the trapping of snapping turtles now. But I did find this informative article in the Baltimore City Paper explaining that trapping snapping turtles was banned in the state in 2009.

Ten years ago I researched an article on the global turtle crisis. Scientists and conservationists said that China’s increasing wealth had just about wiped out wild turtles not only in China, but throughout Southeast Asia. The Chinese were importing turtles from Africa and Australia. At the time scientists feared the crisis would reach the United States.

In the US, the southern states were the first to see turtle exports to China. Is the New York State bill an attempt to cash in on the trade? Current New York State law allows hunters to shoot the turtles with guns or arrow, but not live trap them. The Chinese market demands live turtles.

Snapping turtles are common in New York State and elsewhere. What made the global turtle crisis a crisis, however, is that the that the turtles started out common everywhere, but were quickly wiped out.

New Tech: Ground Penetrating Radar

Texas researchers used ground penetrating radar to study pocket gophers. The researchers were able to map the pocket gopher’s tunnels to a depth of over a foot. They were also able to spot animals within the tunnels and differentiate between and underground pipeline and the pocket gopher tunnels. They wrote about it in a paper in the peer-reviewed journal Wildlife Society Bulletin.

While pocket gophers are a nuisance in places like Washington State, the subspecies studied is a species of concern for the US Fish and Wildlife Service. The research took place on a naval base.

The researchers feel that ground penetrating radar can be helpful in other wildlife management applications.

No Releases for Desert Tortoises

Desert_tortoiseFor decades, captive tortoises have suffered from a mysterious ailment known as “upper respiratory tract disease.” The disease was known in captive tortoises in Europe and the United States, according to information from the California Turtle and Tortoise Club.

Then, in the 1980s wild desert tortoises in California suffered a major die-off from the disease.

The threat of spreading that disease to wild tortoise populations in Arizona is one of the many reasons why the Arizona Game and Fish Department does not allow the release into the wild of tortoises that have been handled for any length of time. The department cares for as many of the tortoises as it can, and also runs an adopt-a-tortoise program.

Last year the department cared for over 40 tortoises at one time.

“I can’t stress enough how detrimental it could be for both the captive and wild tortoises to release a captive tortoise in the wild,” Zen Mocarski, a department public information officer said in an AZGFD newsletter. “Along with potential disease issues and displacement, captive tortoises are not prepared to find food and water in an unfamiliar area and often die.”

Montana Takes Over USGS Gauges

Montana Fish, Wildlife and Parks needs river gauges to determine fishing (and boating) conditions, so when the US Geological Survey said it was going to stop maintaining four of the state’s river gauges because of the sequester’s funding cuts, the state said it would  keep the gauges going.

According to an Associated Press story that ran in the Flathead Beacon, the USGS says it saves about $16,000 a year for each gauge it shuts down. USGS staff visit each gauge about ten times a year to make adjustments for silt build up, channel changes, debris and other river events.

That article and other in the Billings Gazette and Ravalli Republic don’t make clear whether state personnel will take over maintaining the gauges or some other arrangement has been made. It does seem clear, however, that the arrangement will last until September.

Montana’s Department of Natural Resources is also contributing to keep the gauges operational, the Flathead Beacon article says.

Who Should Oversee Deer Breeding and Captive Hunts?

white_tailed_deer_buckThe deer breeding and captive hunt industry would like state departments of agriculture to regulate their industry, rather than state fish and wildlife departments. The industry has made a legislative push throughout the country for more favorable regulations.

A blog in Outdoor Life points out that state wildlife agencies should regulate all of a state’s deer because of the threat of disease — particularly chronic wasting disease (CWD), which is often associated with captive deer hunting facilities, and odd genes escaping into the wild deer herd, not to mention the problem of turning a public resources (wild deer) into private property.

Read the Outdoor Life blog here.

The Associated Press recently ran a story about the controversy over regulating private deer enclosures in Mississippi. The state wildlife department has regulated the facilities since 2008. A legislative committee says it shouldn’t.

Read the story in SF Gate.

Wildlife Professional magazine had an excellent article on this subject back in December. It reviews all the threats to the wild deer herd from captive hunt and deer breeding facilities.

Revised Plan for Ferrets

black-footed ferret“The most feasible action that would benefit black-footed ferret recovery is to improve prairie dog conservation,” said Pete Gober, black-footed ferret recovery coordinator for the US Fish and Wildlife Service in a service press release. “If efforts are undertaken to more proactively manage existing prairie dog habitat for ferret recovery, all other threats to the species will be substantially less difficult to address. Down listing of the black-footed ferret could be accomplished in approximately 10 years if conservation actions continue at existing reintroduction sites and if additional reintroduction sites are established.”

The press release announced a draft of a revised recovery plan for the black-footed ferret.
