Dead Lamprey Juice May Be The Answer

Sea lampreys are the source of much angst among wildlife biologists. Are they native to this body of water? How long have they been here and where did they come from? In many locations, including the Great Lakes, sea lampreys are a huge problem that must be dealt with.

Lampricide, in theory at least, kills larval lamprey but doesn’t harm other stream residents. However some other species are sensitive, and there are always those native, non-trouble-making lamprey to worry about. Dams — temporary and permanent — across breeding streams have been tried, too.

The latest weapon in the war against invasive sea lamprey may be the odor of the decaying lampreys themselves.

Research at Michigan State University showed that the “stink” was easily extracted from rotting lampreys in the lab. Lampreys in tanks and swimming in raceways avoided areas that were treated with the dead lamprey extract.

The dead lamprey juice’s most likely use will be to deter lamprey from certain sensitive breeding streams. Or, it may be used to concentrate lamprey into a few streams so that lampricide applications can be more effective.

Field tests will be conducted this summer.

Can Colorado have both sunflower agriculture and healthy elk and deer herds? That’s the aim of research by Colorado Parks and Wildlife. The three-year project will track 20 elk and 20 deer to learn their migration patterns. The contractor, Quicksilver Air of Alaska used a helicopter and net gun to capture the animals.

The results of the study will allow wildlife biologists and farmers to come up with a plan to keep the elk and deer away from the sunflower crop. The state pays half a million dollars a year to farmers for crop damages, says an article in the Durango Herald.

The detailed article also says that the project will cost $275,000. Similar contractors, the article notes, charge anything from $500 an animal to $1,600 per hour for their services. The collars cost about $3,000 apiece.

Nevada Pulls Up PVC Stakes to Save Birds

PVC pipes are cheap, light and visible from a distance. They are used all over the country as stakes to mark everything from foundation contours to mining claims. In Nevada, it’s the mining claim stakes that are the problem.

Ground nesting and cavity nesting birds are flying into the pipes, thinking they are nesting sites. But the birds don’t get out, because the pipes’ smooth interior doesn’t give them anything to grab on to. The Red Rock Audubon Society says that thousands of birds have died in Nevada in these PVC pipes. They say that bees and lizards are also trapped and die in the pipes.

It’s been illegal to mark a mining claim with an uncapped PVC pipe in Nevada since 1993, but the law has been ineffective. A new state law, SB 108, took effect last week. It allows citizens to remove upright, uncapped PVC pipes on inactive mining claims or place the stake on the ground nearby if the claim is active.

Read about the hazards of PVC pipe markers from the Red Rock Audubon Society. News of the bill’s passing is here.

Read an article in the Las Vegas Review-Journal about the new law.

Here’s the text of the law as it was actually enacted.  You can see the whole history of the bill, including the wording when it was introduced, here.

The law requires that the pipes, whether metal or PVC, be capped or crimped at the top. Comments on the Review-Journal article point out that filling the pipes with dirt would also protect birds, bees and lizards from the pipes too. Claim holders had three years to cap or crimp their pipes before the clause that allows citizens to pull them up took effect.

Grants of up to $1,000 to study prairies and savannas are available from Prairie Biotic Research, a Wisconsin nonprofit organization.

The good news is that these small grants support both natural history and experimental science for any grassland taxon anywhere in the U.S. The bad news (for state wildlife biologists) is that the program is “eager to support” independent researchers. But anyone is welcome to apply. At worst, you can pass this information along to your favorite independent grasslands researcher, and come out a winner anyway.

For more about the organization and past grants, visit the Web site.

For the Prairie Biotic Research’s announcement, follow this post after the break.


FUNDING FOR PRAIRIE RESEARCH
offered by Prairie Biotic Research, Inc.

We Are
Prairie Biotic Research (PBR) is an all-volunteer, Wisconsin nonprofit established in 2000 to foster basic biotic research in prairies and savannas. One way we do this is through a competitive Small Grants Program that funds grants up to $1,000 to individuals for the study of any grassland taxon anywhere in the USA. We support both natural history and experimental science.

We are especially eager to support independent researchers (those lacking institutional support), but anyone may apply. Since 2002, we’ve awarded 100 grants worth $94,849 to people in 24 states to study insects, plants, mammals, reptiles, slime molds, mycorrhizal fungi, spiders, snails, amphibians, invasive species, and effects of management. Many of these grants supported graduate student research.

In 2011, we expect to fund at least 12 grants of up to $1000 each with the donations we have received, including some restricted by donors to support research in the Upper Midwest and in Missouri, where research on Missouri Prairie Foundation properties is of special interest.

To Apply for a Grant 
Visit our website (prairiebioticresearch.org) to learn more, to download our proposal form, instructions, and a sample researcher agreement form that winners of this competition must sign. Check out the history and overview files in the Small Grants section of the website to see what sorts of proposals have won funding in the past. Review the reports submitted by researchers of past years.

We must receive your proposal through the mail before January 7, 2011. Those who won funding in 2010 are ineligible for this funding in 2011, but those who won funding longer ago are welcome to submit proposals to further that same work or to support a new project.

Our Supporters 
 We are grateful for gifts recently received from individuals, foundations and nonprofit organizations in support of our Small Grants Program: Andria Blattner, Kurt Christoffel, Citizens Natural Resources Association of Wisconsin, Robert & Nancy Dott, James E. Dutton Foundation, Hildy Feen, Tamara Felden, Catherine Gimse-Owen & Robert Owen, Don & Helen Hagar, MJ Hatfield, Hillsdale Fund, George & Marilyn Johnson, Kyle Johnson, Herbert H.

Gold: A New Threat to U.S. Streams

Posted on by

With gold at $1,600 an ounce, recreational gold panners are getting serious — serious enough to have an impact on stream environments. That’s the case in North Carolina, where a local land trust closed its property to gold prospectors recently, and the Uwharrie National Forest banned suction dredging several years ago.

Read the story in the Charlotte Observer, here. (Oh, and you’ll have to forgive the headline, which refers to “marine life.” Clearly, the article is referring to aquatic life in central North Carolina, far from the ocean.)

Think that no one is panning for gold in your state? Think again. Placer gold, the kind found in stream sediments, has been found in just about every state. Panning for gold is sometimes unregulated, and where it is regulated, misconceptions and plain old ignorance abound. The real damage comes from mechanized panning, such as suction dredging.

Is the critical habitat for your sensitive aquatic species safe from gold panning?

Don’t forget: Endangered species habitat grants

The U.S. Fish and Wildlife Service is now accepting applications for its Cooperative Endangered Species Conservation Fund grants. The deadline for submitting proposals is January 27, 2012. The grant pays for land or planning to protect rare species. The funds can be used for projects for species that are candidates, proposed, or listed under the Endangered Species Act.


Your state will have to kick in some of the funds, though. The grants cover 75 percent of the project cost for single state or territory; and 90 percent for two or more states or territories implementing a joint project.

Visit the US Fish and Wildlife Service Endangered Species Program page for a press release announcing the grants, a 45-page document describing the grants in detail, a press release announcing the last cycle’s winner, plus a report on the winning projects. The page also includes other federal grant resources.

EHD in Maryland

Posted on by

Epizootic hemorrhagic disease (EHD) was reported in white-tailed deer in Maryland last week, but it seems likely that the outbreak will be short-lived. Biting midges, or no-see-ums, transmit the disease-causing virus, and outbreaks generally end with a hard frost.

Western Maryland, where the two cases of EHD were reported, received about six inches of snow this weekend. That should end the biting midges’ party for the season.

Read the article on the outbreak in the Hagerstown Herald-Mail.

I couldn’t find a Maryland Department of Natural Resources press release on the outbreak, but the department does have an EHD fact sheet on-line.

As the Herald-Mail article mentions, Chronic Wasting Disease (CWD) is a much bigger concern than EHD in this southern-ish state. Here’s our post on CWD in Maryland.

Also, read this previous post on EHD for links to more information on the disease.
