Christine Wilcox writing her NRDC blog laments the fact that the Avalanche Peak Trail in Yellowstone Park which once harbored Grizzlies, seems to be devoid of this species currently due to the demise of one of their key foodstuffs--Whitebark Pine seeds----Global warming has enabled the native Pine Bark Beetle to up the ante on the trees---As Christine writes: "This is not a new species of beetle; it has been around for thousands of years and has coevolved with lodgepole pine at lower elevations"............ "During this coevolution, successive generations of lodgepole pine trees developed physiological and chemical defense mechanisms to prevent fatal beetle infestation"......... "Whitebark pine trees grow at higher elevations and have not changed significantly in an evolutionarily sense, because until recently there was no such threat to their survival"............ "What's new is that the warmer temperatures have allowed the beetles to survive the winters affording the beetles the opportunity to invade trees in higher elevation areas as a result"............ "Combined with the fact that whitebark pine trees have fewer defense mechanisms against pine beetle attacks than other trees, we are left with a forest of firs, spruces, lodgepole, and a bunch of dead whitebark pine trees"..............."As we approach the petition by the government to again de-list the grizzly bear as a threatened species protected under the Endangered Species Act as early as 2014, we know that the current status and predicted future of whitebark pine trees is an important factor".............. "Unfortunately, not everyone is listening to that information"........ "Some are carelessly assuming that the grizzly bear as a flexible omnivore will adapt to this widespread loss of a key food source"........... "It is estimated that at least 70% of all whitebark pines in Yellowstone have been lost in the last decade or so to beetle infestation".......... "With no end in sight to global warming trends, it is possible that we will functionally lose this species in the Yellowstone ecosystem entirely, perhaps even within the next century"-----Will the "Griz" be able to adapt????????????

“If you kill a big adult male(PUMA), three male ‘teenagers’ will come to the funeral”.................. "The behavior of the youngsters is different from their older counterparts"........... “They’re teenagers,",,,,,,,,,,“They’re sexually mature, but mentally they are not all there.”............ "The adolescent cougars are more likely to get into trouble with humans and our livestock than are the more mature toms that want to stay away from danger"............ "As it happens, adolescent males have bigger territories than the adult males"........ "This means that livestock and elk might have to cope with either one mature tom or several adolescent males that replace him".......... "With multiple male cougars in an area, trouble is multiplied"............ "Cougar complaints, livestock kills and pet kills all actually increase with increasing hunting mortality of cougars".-------Robert Wielgus; Washington State University Large Carnivore Lab-------This Blog has discussed the insights of Wielgus's research before............ it is now a pleasure to know that as a result of his work, Washington State is going to limit cougar hunting to 14 percent of the cougar population(a % that will not tamp down the Puma's ability to survive, multiply and persist into the future)............ Once hunters have harvested that figure, hunting will be suspended in an area for the rest of the year............. “The results of this work are a win-win for cougars, livestock operators, and threatened prey species

Whether in the Rockies or the Great Lakes, when it comes to the mandates put in place regarding hunting Wolves,,,,,, as biologist Peter David puts it: “I’m concerned about the impact it is going to have and the lack of science built into the hunt” ...........Wisconsin which is starting its first Wolf hunt tomorrow, seeks to reduce its population from the current 850 animals down to 350--a potentially staggering reduction of nearly 60%!---some scientists say, this hunt could push the number of wolves to a tipping point, beyond which their numbers might again quickly drop to the level that would put them back on the endangered list — 250 wolves........And like seemingly every decision about wildlife made lately, what is not put into the equation is the Wolf mortality that occurs above and beyond what occurs during hunting season:............ Adrian Wydeven, a DNR wolf researcher who has helped manage the species’ recovery in the state, said it is important to remember the number of wolves killed during the hunting season has to be added to all the wolves killed in other ways throughout the year to get an accurate picture of how total human-caused wolf deaths are going to affect the statewide population..............Wisconsin population studies have shown 9 to 19 percent of the state’s wolves are illegally killed each year, 10 percent are killed in depredation control programs, and 3 percent to 4 percent are killed by vehicles............. Add those numbers to the 24 percent harvest quotas and total, human-caused mortality is likely to be between 46 percent and 57 percent................. Research has shown that wolves can tolerate up to about 29 percent to 35 percent human-caused mortality rates before populations decline............... .....Wydeven cited studies that have shown eliminating certain individuals — those wolves that breed, for example — and reducing the size of packs can dramatically reduce pup survival.................. And the effect of removing breeders from packs was much more detrimental in smaller, recovering wolf populations similar to Wisconsin’s......Studies have shown as well that disrupting packs and removing alpha wolves can actually increase the likelihood the rest of that pack will be forced to prey on easier-to-capture livestock for food................. There is certainly reason to believe that this hunt is going to be highly disruptive socially...............Studies in Canada’s Algonquin Park that showed excessive hunting mortality might disrupt the kin-based social structure of packs and encourage hybridization of wolves with other canids, such as coyotes................. Great Lakes wolves are known to hybridize with dogs, something biologists want to avoid, partly because such wolf-dog hybrids can exhibit unwanted behavior such as lurking too close to humans and preying on livestock...............Bottom line is that most Biologists believe that people are going to look back at this, and it will have become a textbook example of how not to hold a hunt!
