Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

Mississippi bears took a hit from the flooding that occurred last year in the region........The State has a recovering 120 Bear population that is still considered endangered.........Breeding females have had litters for 8 consecutive years so we hope that Mother Nature doesn't open up the floodgates again this Spring allowing a higher % of cubs to survive the first 16 months that they are with their mothers

Flooding may have taken toll on Mississippi bear cubs

Mississippi Wildlife and Fisheries biologist Brad Young measures a baby black bear cub in Bolivar County last week. Last year's Mississippi River floods may have killed a number of black bear cubs in Mississippi, says  BradYoung,  Dept of Wildlife
Last year's Mississippi River floods may have killed a number of black bear cubs in Mississippi, the state's black bear program leader said. Three radio-collared females known to have had cubs this year had also given birth a year ago, said Brad Young of the Mississippi Department of Wildlife, Fisheries and Parks. "Cubs stay with their mothers for 16 months," he said. "What we're taking away from this is that the litters of all three of those females were killed by high water. That's why they had litters this year."
Young said about 120 black bears live in the state — at least 80 percent of them are Louisiana black bears and the rest American black bears. With numbers of both subspecies so low, Mississippi has listed all black bears as endangered.

"While the flood didn't have much effect on adult bears, obviously it had a big effect on our cub survival from last year," Young said.The data gathering on the bears and the apparent effects of the flooding continues, so the analysis is not yet complete.

State wildlife agents and University of Southern Mississippi graduate students have collaborated since 2005 to check on whether any females with radio collars have had cubs. Seven females currently have the collars, and three of them gave birth. The researchers couldn't get to a fourth. "We're almost positive she has cubs," Young said. "But she was holed up tightly in a tree that we couldn't get down into. Three more we know did not have cubs this year."

This year's known mother bears include a Louisiana black bear checked March 1 in Issaquena County and two American black bears checked Monday in Bolivar County. The Louisiana black bear and one American black bear had one male cub each; the other Bolivar County bear had quadruplets: three females and a male.

"Back in 2005, we had a litter of five, which is just freakish by most standards in the Southeast. Since then, this is by far the largest litter we had," Young said. Although all were healthy when weighed and measured Monday, it's unlikely that all cubs in such a large litter will make it. "That's not to say they couldn't all survive — that's certainly possible, especially in ideal habitat like we have along the river," Young said. "But usually — the law of nature — the smallest will fall behind, become malnourished and susceptible to disease or exposure."

He said it's the eighth year in a row that cubs have been documented in the state. "Which isn't a big deal in a lot of the states," Young said. "But when you consider that, prior to 2005, it had been probably 40 to 50 years since we had documented the birth of bear cubs in Mississippi, it's a very positive trend."

To document and track cubs, a wildlife agent tranquilizes the mother with a dart while she's in the den. Those may be on the ground or high in a hollow tree, but the agents can get up trees so quietly that the bear doesn't know they're coming, Young said
Then the agent takes the cubs out of the den. They get weighed, measured, and implanted with a microchip between their shoulders just like the microchips used to identify cats and dogs. After that, the mother's radio collar is replaced so it will last until the next spring."We put the whole family group back together and leave them in the den," he said.
