Wildlife Flees Floods

Today’s NOAA flood warnings

Wildlife is fleeing the major flooding along the Mississippi River. (There is also major flooding today on the James River in South Dakota and Lake Champlain in Vermont.)

–ABC News focuses on the danger of snake bites to residents in the flood zone.

-Articles in the The Desoto Times Tribune (Miss.) and the Natchez Democrat focus on deer fleeing the floodwaters, and quote state wildlife officials saying that all hunting regs still apply.

-One Louisiana parish is asking the state Department of Fisheries and Wildlife to double hunting fines during the flood emergency.

-A Vermont story focuses on flooding’s impacts on plant habitat, the threat to a rare tern, and the bumper crop of mosquitoes to come.

State Wildlife Biologists Wanted for Bat Survey

Mobile bat detector
A coalition of federal and state agencies is looking for wildlife biologists to lead and organize acoustic surveys of bats in all 50 states. (Actually, the program has at least some data from 24 states, but only New York is thoroughly covered, so more leaders are needed just about everywhere else.)

The coalition hopes to gather general population data on bats, particularly as these animals face two threats: white nose syndrome, and wind power development. Surveys specific to the sites of those threats don’t give needed information about bat population trends in general.

The survey protocol uses your real-time recording bat detector (such as those from Anabat or Binary Acoustic Technology) mounted to the roof of a car (with materials available cheaply from home improvement stores). The trickiest part may be planning the transect, which should be 20 to 30 miles long, and driven at very close to 20 mph. If it is a loop, it should be wide enough so that you are unlikely to encounter the same bat twice. The surveys should take place at sunset, on evenings that are over 50 degrees F, with low wind, and no rain.

Organizing a statewide survey is easy, say the organizers. New York covers the entire state with 80 volunteers and one coordinator. They cover 50 transects, two or three times a year.

Finding the citizen volunteers has been easy, but finding qualified wildlife biologists to lead state programs has been more difficult. Susi von Oettingen, of the US Fish and Wildlife Service, said in her presentation on the survey project at the Northeastern Fish and Wildlife Conference last month that state wildlife biologists are the ideal leaders.

Free training materials are available to leaders. For more information on the project, and how to get involved as a leader, visit the project’s Web site, which includes a video of a presentation of the project, plus a PowerPoint presentation.

Swans were poisoned, not shot

In January five trumpeter swans were found dead around the Dungeness Valley on the Olympic Peninsula in Washington State. One of them was believed to be shot because X-rays showed 41 shot ­gun pellets in the bird’s body. Trumpeter swans came near to extinction at the beginning of the 20th Century, and while they have recovered, the number of deaths in one area, and the possible shooting, were a concern.

However, further tests showed that all five of the swans had lethal levels of lead in their livers.

Local wildlife managers don’t know where the swans could have ingested the lead shot. Swans and other birds swallow stones and grit to help them grind up food in their gizzards. The wildlife managers will keep an eye out for further lead poisoning cases in the region in the future.

Read more info in this report from a local radio station. And in this article from the Peninsula Daily News.

I tried really hard to work in an “eat lead” joke here, but I just couldn’t do it.

Banning felt waders

Maryland, Vermont, and Alaska are the first states to ban felt-bottomed fishing waders in an effort to slow the spread of the algae known as didymo, and other invasive species. (Well, the Alaskan ban doesn’t take effect until next year, but it is on the books.)

Idaho and Oregon tried to ban felt waders, but the legislation didn’t pass, reports this USA Today story on the wader ban. Nevada will consider a ban as part of an invasive species plan, the article says.

Missouri has taken another route. It is using wader washers at the state’s four trout parks. Read all about it in the Missouri Department of Conservation press release. Info about the wader wash stations is half-way down, below the list of phone numbers. One Ozark skeptic opines here, but gives many more details about Missouri’s attempt to slow didymo by educating anglers.
