Fish and Wildlife to the Rescue

Florida panther kitten FWCFish and Wildlife personnel rescue wildlife all the time. Sometimes they rescue rare wildlife. But this week there were two rescues of critically endangered species in adjoining states. Actually, Florida Fish and Wildlife Conservation Commission staffers were involved in both rescues.

Off the coast of Georgia, a rescue team that included Georgia Department of Natural Resources biologists cut over 100 yards of heavy fishing rope from a 4-year-old male North Atlantic right whale, allowing it to swim more easily. The young whale one of only about 450 remaining North Atlantic right whales.

In Florida, biologists from the Florida Fish and Wildlife Conservation Commission (FWC) and the Conservancy of Southwest Florida discovered an approximately week-old Florida panther kitten while conducting research at the Florida Panther National Wildlife Refuge in Collier County in mid-January.

There are 100 to 160 Florida panthers in the wild today, but this kitten will no longer be among them. Because it is too young to have learned survival skills from its mother, it will have to live in captivity. But with a gene pool this small, even captive individuals help with diversity.

LA Mtn. Lions Need Overpass

mo mountain lionThere is a small population of mountain lions in the Santa Monica Mountains, just northeast of Los Angeles. The problem is, an article in the LA Times says, the population is hemmed in by highways, agricultural fields and the ocean, and is too small to be self-sustaining. Wandering male mountain lions typically die in traffic before reaching the enclave, causing inbreeding.

The solution, say some area conservationists, is a highway overpass. Twice before, funding for a wildlife tunnel under the roadways was rejected. The overpass would cost a lot more. The next step is funding from a local conservation group for the California Department of Transportation to study the overpass option.

More Mountain Lions

mo mountain lionWhere are there more mountain lions? There are increases Puma concolor sightings just about everywhere, recent news reports say.

An article in The New York Times focuses on mountain lions’ expansion east from their strongholds in the Rocky Mountains and Texas. The article says that mountain lion sightings are now common in the Midwest, and it includes a map that shows recent sightings, including several in New England.

In Arizona, an abundance of mountain lions in the Catalina Mountains has some folks worried about a planned release of bighorn sheep there, says an Arizona Daily Star article. A management plan calls for killing mountain lions that kill the bighorns, although the mountain lions should have plenty of other prey, the article quotes Jim Heffelfinger, regional game specialist for the Arizona Game and Fish Department as saying.

An increase in deer in the area likely lead to the increase in mountain lions, the article says.

Mountain lion populations have been going up in California for at least 20 years, with hundreds of sightings annually, but that doesn’t mean the sight of two mountain lions in Redlands, California isn’t news. Redlands is near the San Bernardino Mountains, east of Los Angleles.

Mountain Lion Research

mo mountain lionWhen it comes to mountain lions making use of suburban habitats, there is no difference between males and females, or resident and transient animals, but sub-adult mountain lions were more likely to be found in the suburbs, a study published in the Journal of Mammalogy found. The study was conducted in western Washington State.

The study suggests targeting problem individual mountain lions, maintaining older age structures and other methods to decrease contact between humans and mountain lions.

Wolves seem to be knocking back the mountain lion population in Wyoming’s Teton Mountains, and they seem to be targeting mountain lion kittens, says Mark Elbroch, a researcher with the Teton Cougar Project in an article in the Jackson Hole News & Guide. It’s competition, not predation, the article states.

The Teton Cougar Project both collars mountain lions and observes them through video cameras set up at bait stations. The article reports that project scientists will publish three papers in the coming year. Read more about the research in the Jackson Hole News & Guide article, here.

The Teton Cougar Project is a partnership between Panthera and Craighead Beringia South.

Old-timers Keep Mountain Lions Stable

In January, the Washington Department of Fish and Wildlife will begin using “equilibrium management” to determine the number of mountain lions (or cougars, Puma concolor) taken by hunters in each management unit, according to a press release from Washington State University. This will limit the take to the natural amount of reproduction — 14 percent, according to the release.

Research by Washington State University’s Large Carnivore Conservation Lab has found that mature, adult male mountain lions are the lynchpin of the species’ population dynamics. According to the press release, mature males will kill younger males to protect their territories, keeping the overall population low. The mature males are also less likely to prey on livestock.

There is no word, however, on how using equilibrium management will prevent hunters from killing all the mature males in an area, therefore releasing the less stable younger males.

Several news outlets have published the press release with no additional reporting. Read the press release here.

Resident Mountain Lions in Michigan?

Mountain lion sightings have been confirmed 15 times in the last several years, the Detroit Free Press reports. The article says that the Michigan Department of Natural Resources believes that the mountain lions are just passing through and that there is no resident population in the state.

However, the Michigan Wildlife Conservancy, a non-profit organization, maintains that the sightings mean that there is a breeding population in the state. Google says that the organization’s site may be compromised, but a link to mountain lion info is front and center on its webpage. (“Cougars in Michigan: We proved they are here. Will you help protect them?”)

An article in the (Michigan) News Herald provides the details on the the group’s announcement. Read the News Herald article here.

Missouri Lions Are From All Over

A Missouri Department of Conservation (MDC) press release says that DNA test results show that four of the 14 mountain lions seen in Missouri last year came from three Western states.

MDC was able to document 12 of the 14 sightings, and four of the documented sighting yielded enough hair or tissue samples to do DNA testing on. DNA tests tied two young male cougars, one from Ray County and the other from Texas County, to the Black Hills area of South Dakota. DNA showed that a Macon County mountain lion was from central Montana. A mountain lion spotted in Oregon County was related to mountain lions from Colorado.

What was going on with mountain lions in Missouri last year is anyone’s guess. Previously, the highest number of sightings in the state in a year was two. This year there have been two as well.

“Increased public awareness and the growing popularity of trail cameras might account for part of the increase in sightings,” says Missouri resource scientist Jeff Beringer in the press release, “but last year’s spike is hard to explain. What we now know for sure is that mountain lions are traveling a long way to get here.”

Research: Screech Owls, Urban Coyotes and Social Mountain Lions

Forest cover is the best predictor of screech owl presence, and citizen scientists doing call-playback surveys compared well to professionals, says a paper in the March issue of the Northeastern Naturalist. The research was conducted in the metropolitan New York tri-state area.

Read the abstract here. (Fee or subscription required for the full article.)

Teton Cougar Project, which has been studying mountain lions (Puma concolor) in the Jackson Hole region for years, recently documented two adult female mountain lions feeding at the same kill on three different occasions. Once, a male also joined the group. Four years ago the research team documented one female mountain lion adopting another’s kittens.

The observations refute the conventional wisdom that mountain lions are solitary and only spend time together to mate.

Researchers in Denver, Colorado will begin radio-collaring up to 60 coyotes in the metro area with the goal of tracking them for the next two years. Stewart Breck, a researcher with USDA-APHIS Wildlife Services, will lead the effort.The researchers would like to know how the coyotes are using settled landscapes, and if community-based hazing programs are working.
