Got Mink?

mink-at-denThe Florida Fish and Wildlife Conservation Commission (FWC) would like to learn more about Florida’s three subspecies of mink, and it is reaching out to the public for help.

“We know that mink are more likely to be found in and near salt-marsh habitat on both coasts of Florida but the reports people provide will help us pinpoint where we do research,” said Chris Winchester, wildlife biologist with the FWC’s Fish and Wildlife Research Institute in a press release issued by the commission this week.

For reasons unknown, mink appear to be absent from the freshwater streams, rivers and wetlands of central and northern Florida, the commission website says.

The effort includes an on-line mink sighting registry that includes a mapping tool. A similar Google Maps tool was used in a FWC public outreach effort to locate fox squirrels. That effort was quite successful. We covered it back in October 2011.

Bat Movement Study

cumberland gap wns batBats move around a lot. Some bats migrate. Some bats move from summer or maternity roosts to winter hibernation caves. Finding out how bats move has suddenly become extremely important. White nose syndrome seems to be following the known patterns of bat movement. But just so little is known.

Erin Fraser used stable isotopes to study the migration patterns of tri-colored bats (aka eastern pipistrelles) for her doctoral work at Western University in London, Ontario, Canada. Bat Conservation International helped fund the work, so they have lots of details in their newsletter, here.

You can learn more about using stable isotopes in ecological research in this article in the online publication Yale Environment 360, here.

19 New Protected Species in Nova Scotia

plymouth gentianNineteen new species have been added to Nova Scotia’s list of species at risk, bringing the total listed in the province to 60, according to a Nova Scotia Department of Natural Resources press release and a CBC News report.

Three bat species are on the list, including the little brown bat, the northern bat and the tri-colored bat, which are all listed as endangered. Three bird species have been added to the list as endangered: the barn swallow, Bicknell’s thrush, Canada warbler, and the rusty blackbird. The olive-sided flycatcher and the eastern whip-or-will have been listed as threatened.

The black ash tree is listed as threatened. There are only 12 known mature trees in the province, the department press release says.

For the complete list of species, see the Nova Scotia DNR website, here. (New species are marked with the year 2013.)

NPR on Sage Grouse Initiative

Sage Grouse vs transmission linesOn Wednesday, NPR had a piece on the Sage Grouse Initiative in Montana. There are photos and audio (or you can just read the article).

The initiative was started by USDA’s Natural Resources Conservation Service, the piece says. It was joined by The Nature Conservancy, universities and state wildlife agencies. The initiative’s key tools seem to be portable electric fences, and widely distributed watering sites. That’s because having cattle graze intensely in small areas, leaving the grass in other areas to grow tall, as the sage grouse like it, is the goal of the program.

While sage grouse are found in only a few states, the effort to keep the species off the federal endangered species list should be of interest to all wildlife managers, particularly those managing other species at risk. At what point should we take action to keep a species from being listed? At what point does the species need to be listed so the protections of the Endangered Species Act can kick in and save it from extinction?

Stay tuned.

Counting Bats

P1040280Because of white nose syndrome (WNS), counting bats is more important than ever. In regions where WNS has already struck, wildlife researchers are tracking survival rates. In regions where it hasn’t struck, wildlife researchers are collecting baseline data.

In Georgia, volunteers are using Anabat bat detectors to assist the Georgia Department of Natural Resources’ Nongame Conservation Section in their counts. Read the story in the Augusta Chronicle.

In Long Cave in Kentucky’s Mammoth Cave National Park they are using LIDAR, a combination of light and radar, to count bats without disturbing them. This technology seems like a dream come true for bat biologists in the age of WNS. Bat Conservation International partnered with the Cave Research Foundation and the U.S. National Park Service to test the new technology.

Learn more about the technology and the test in the Bat Conservation International newsletter, here.

Vermont Fish and Wildlife is conducting its third year of summer bat surveys. The surveys are mostly done the old-fashioned way, by squinting into the dusk and counting, but the surveyors also have use of an Anabat and night vision goggles. In certain locations they trap and sometimes radio tag bats.

I know all about it, because I wrote an article, but I can’t link to it because it is behind a paywall. If you happen to have a subscription to the Rutland Herald, you can read it here. (Although I suspect that link isn’t good for long either.)

Sage Grouse and Antelope Down in South Dakota

Sage Grouse vs transmission linesThe sage grouse population has fallen in South Dakota in recent years, reports an Associated Press story in the Daily Journal. To let the population rebound, the state’s Game, Fish and Parks Commission decided not to have a sage grouse hunting season this year.

Read the Daily Journal article, here.

The state’s antelope population has not rebounded after a recent decline, but in that case the state will limit hunting licenses for firearms to South Dakota residents, the Mitchell Daily Republic reports. Archery hunting licenses will be available to residents and nonresidents.

Wisconsin Nongame Program Changes Name

Wisc DNRAfter 40 years as the Wisconsin Bureau of Endangered Resources, the program charged with caring for that state’s endangered resources is now known as the Bureau of Natural Heritage Conservation. The change took place on July 1.

“Our name has changed but our mission is the same,” says Erin Crain, who took over in October 2012 as bureau director, in a Wisconsin Department of Natural Resources press release. However, the same press release mentions changes in organization and budget with the goal of filling long-standing vacancies in field positions.

USGS River Gauges and Sequestration

river gauge mapOne way for the federal government to save money is to turn off any number of the 7,000 river gauges installed and maintained by the US Geological Survey. Each gauge costs $14,000 to $18,000 a year to maintain, High Country News reports.

High Country News also reports on which river gauges in the West are most likely to be shut because of sequestration or other budget cuts.

We pointed you to an article about Montana’s last minute rescue of some of that state’s river gauges in May. That arrangement lasts until September.

Because river gauges are such a vital tool in managing river ecosystems, we thought you would like to know.

Did Bear Poachers Retaliate?

Black bearEarlier this month 11 defendants were sentenced as the result of a four-year undercover investigation of bear poaching in North Carolina and Georgia. The effort, known as Operation Something Bruin, involved two state and three federal agencies.

Of those defendants, only one was actually charged with poaching a black bear. Read the press release on the Operation Something Bruin website.

The Asheville (NC) Citizen-Times reports that authorities are investigating a bear that was killed, painted with the words “Whats Bruin” on its head and paws, and dumped in Buncombe County, NC. The authorities believe the phrase refers to the investigation, the paper says.

The US Fish and Wildlife Service and the US Forest Service are offering a $3,000 reward for information that leads to a conviction, the Citizen-Times reports, while the NC Wildlife Federation put up an additional $17,000.

Round-up of New Hamphire Nongame Programs

nh logoThe N.H. Fish and Game’s Nongame and Endangered Wildlife Program celebrates its 25th anniversary this month. From a department press release, here are some of the projects that the program is involved with:

“KIDS FOR KARNERS” started in 2000 as a way to engage area school children in the Karner blue butterfly and Concord Pine Barrens project. Every winter, biologists go into classrooms where they talk to kids from pre-K through high school about the project. The students then plant wild lupine seeds and take care of the plants until May when they come to the Concord Pine Barrens to plant their wild lupine plants. Learn more at http://www.wildnh.com/Wildlife/Nongame/projects/karner_project.html.

PROJECT OSPREY: Fish and Game’s Nongame and Endangered Wildlife Program joined forces with Public Service of New Hampshire (PSNH) and New Hampshire Audubon to work toward a full recovery of the state-threatened bird of prey by the end of 2005. Learn more at http://www.wildnh.com/Wildlife/Nongame/project_osprey.htm.

NH DRAGONFLY SURVEY started in 2007 as a partnership of NH Audubon, NH Fish and Game, and University of New Hamphire Cooperative Extension. Its goal is to gain a better understanding of the distribution of dragonfly species of conservation concern in New Hampshire. In the first four years of the project, over 200 people attended workshops intended to train volunteers in dragonfly biology and data collection methods. Learn more at http://www.wildnh.com/Wildlife/Nongame/dragonflies.html.

REPTILE AND AMPHIBIAN REPORTING PROGRAM (RAARP) encourages volunteers to report sightings of reptiles and amphibians from spring peepers to snapping turtles. These reports are extremely valuable to biologists. Observations are used to determine the distribution of reptiles and amphibians within New Hampshire. Verified reports of rare species locations are mapped and stored in a database used for land protection and conservation purposes. Learn more at http://www.wildnh.com/Wildlife/Nongame/reptiles_amphibians.htm.

TAKING ACTION FOR WILDLIFE is a collaboration between the NH Fish and Game Department and University of New Hampshire Cooperative Extension to help communities, conservation groups and landowners conserve wildlife and habitats in New Hampshire. The website contains many resources that can help you get involved in efforts to protect, restore and learn about wildlife and habitats. Visit http://extension.unh.edu/fwt/tafw/index.htm.
