Elk Killed by Blue-Green Algae

More Cervid Contraception: GonaCon and ElkOutbreaks of blue-green algae are a growing plague across the country. Pollution plays a role, by providing nutrients (the pollution is typically fertilizer, but also detergents containing phosphates) that allow the algae (which isn’t really algae, but a photosynthetic bacteria — read more here) to grow to unnatural levels.

The toxins in blue-green algae can kill animals such as dogs or cattle that drink the water. Children are at higher risk from blue-green algae toxins than adults for the same reason; they are more likely to drink water while swimming. Hot weather and still lakes or ponds make things worse, leading some states to produce regular reports on where blue-green algae is found.

A mysterious die-off of 100 elk in New Mexico appears to have been caused by blue-green algae, an article in the Southwest Farm Press reports. Biologists from the New Mexico Department of Game & Fish considered many common causes of elk death, including epizootic hemorrhagic disease, anthrax and lightning.

A search of nearby water sources found blue-green algae in fiberglass water tanks in the area where the elk died, but not in ceramic water tanks in the same area. Just another possibility to consider when you are faced with an unexplained wildlife die-off.

Plague: Human Cases in NM, Squirrel Case in Cal.

New Mexico has had all three cases of plague in humans that have occurred in the United States this year, a New Mexico Department of Health press release reports.

Read the press release here. (Will open a PDF.)

The bacteria that causes plague is endemic in the southwestern US. Wildlife cases are so common that I don’t report them here, but those cases can be an important warning to locals to take extra care to keep their pets away from wildlife and to avoid flea bites, and for wildlife managers and researchers to take precautions as well.

Just such a warning is in place in Palomar, California, where ground squirrels at a campground have been diagnosed with plague.

Critical Habitat Assessment Tool for Lesser Prairie Chickens

lesser prairie chickenFrom a press release issued by the Oklahoma Department of Wildlife Conservation and the Kansas Biological Survey:

In cooperation with the five state fish and wildlife agencies that fall within the range of the Lesser Prairie-Chicken (LEPC), and the Western Association of Fish and Wildlife Agencies (WAFWA), the KARS program has launched version 2.0 of the Southern Great Plains Crucial Habitat Assessment Tool (SGP CHAT). The online map viewer hosts the SGP CHAT, which is the spatial representation of the LEPC range-wide conservation plan, and a tool that prioritizes conservation actions while assisting with the siting of industry development.

3rd Draft for Prairie Chickens

SAMSUNG DIGITAL CAMERAFive states submitted a plan for conserving lesser prairie chickens to the US Fish and Wildlife Service last week. It is the third draft for the plan, Lone Star Outdoor News reports. The five states are Colorado, New Mexico, Texas, Kansas and Oklahoma. The multi-state conservation plan is a bid to keep the bird of the federal endangered species list.

The planning process began a year ago, in April 2012. The USFWS will make its final ruling on September 30, 2013.

NM Crane Mystery

mystery crane NMIt’s not so much of a mystery, as a quirky little crane that has attracted media attention nationwide. Back in November, Bosque del Apache National Wildlife Refuge in New Mexico posted a photo on its Facebook page of a crane that was darker, thinner, smaller and had more compact feathers than the flock of sandhill cranes it was with.

The refuge is known for its sandhill cranes, so it made sense that this was simply a color morph, or a crane that had preened dark mud into its feathers. But the guessing game had begun, with the most outrageous guess supposing that this was a hybrid between a sandhill crane and a trumpeter, native to South America.

The photo of the bird that is getting the most exposure is by Clint Henson of the New Mexico Department of Game & Fish.

Read more about the guessing game in the San Francisco Chronicle, here.
The Bosque del Apache NWR Facebook page is worth a visit just for the many stunning photos, of cranes, other creatures and beautiful vistas.

Oil, Politics and Lizards

The US Fish and Wildlife Service announced yesterday that the dunes sagebrush lizard (Sceloporus arenicolus) would not be listed under the Endangered Species Act because voluntary conservation methods undertaken by private landowners in Texas and New Mexico have worked so well.

The most interesting thing about the dunes sagebrush lizard is that its habitat happens to be among the richest oil-producing regions in the lower-48 states. A listing would curtail drilling for oil and gas in the region, so it’s no surprise that the oil industry has fought against a federal listing for the lizard for decades.

Is the decision a victory for the oil industry? For conservation agreements? For the lizard?

That certainly depends on your point of view. You can see two different points of view on display in these articles. The Reuters report buries the information that environmental groups are unhappy with the ruling, and gives only a tepid quote from one of the organizations that disagrees. Read the Reuters piece here.

The Fort Worth Star-Telegram puts environmentalists’ displeasure at the top of the story and includes a more forceful quote from the same source. Read the Star-Telegram report here.

A KXAN TV story provides some helpful details.

Chronic Wasting Disease Update

CWD risk in Ontario

Three more cases of chronic wasting disease (CWD) were confirmed in wild white-tailed deer in Missouri last week. These deer had been killed within two miles of the free-ranging deer found to have CWD last fall.

Read the Missouri Department of Conservation press release, here.

The situation in Virginia is similar. “Two new cases of chronic wasting disease (CWD) have been detected very close to where CWD-infected deer were found in 2009 and 2010,” the Virginia Department of Game and Inland Fisheries press release says.

CWD has been found in mule deer in New Mexico for 10 years, but this year it was detected in deer not far from El Paso, Texas, which has the Texas Parks and Wildlife Department on alert. Read an article about this in the Lonestar Outdoor News.

There’s no CWD in Ontario, Canada yet, but they are keeping an eye out for it, since it has been found in the neighboring US states of New York, Minnesota and Michigan. The Ontario Ministry of Natural Resources recently released a seven-page report about its surveillance program. (Be forewarned, that link will pop up a sizable PDF.)

Wildlife Disease Roundup

Dozens of white-tailed deer in Montana have died of a mysterious ailment which is suspected to be epizootic hemorrhagic disease. The Great Falls Tribune has a brief item. Check out this item on ProMed-mail for a helpful reference to the no-see-ums that transmit the disease.

[ADDITION: The day after this was posted, the state of New Jersey announced epizootic hemorrhagic disease in deer in that state. You can read the press release here.]

A feral hog in Midland County, Michigan has tested positive for pseudorabies. Read the article on Michigan Live, here. Sounds ridiculously scary until you find out that porcine pseudorabies has nothing to do with rabies. It’s a herpes virus, and it doesn’t effect humans, but it does kill dogs and other animals, wild and domestic. Once again, ProMed-mail has the needed explanation. Read it here.

Also in the catagory of “needed explanations” and “wildlife disease” is a recent report in the Los Angeles Times of the “first U.S. transmission” of rabies linked to a vampire bat. Uh, no. Even the article says the man was bitten by a vampire bat in Mexico, then traveled to the U.S. Unfortunately, the story was also picked up on the gossip site Gawker.com. Here’s the LA Times story. And here’s a debunking from a biology professor at Long Island University

Finally, the Wisconsin Department of Natural Resources recently launched a new Web site on chronic wasting disease, aimed at hunters. Find the Web site at http://www.knowcwd.com/ And find an article about the Web site and Wisconsin’s “Know CWD” campaign in the Houston Chronicle.

There were just no pretty pictures for this one. Not even a nice picture of a virus available.

New Mexico Withdraws From Wolf Recovery Program

New Mexico recently pulled out of the Mexican Gray Wolf Recovery Program, an experimental program that began releasing wolves into the wild in 1998. Read the latest on the wolves, and the New Mexico decision in this article in the El Paso Times.

For more on the program, visit the US Fish and Wildlife Service’s Web site. For an eye-opening look at the twisted path this program has taken, be sure to check out the chronology. It would have made a great reality TV show.
