I’ve been writing a lot of blog posts on grizzly bears for a good reason–to raise awareness that these magnificent animals are headed for delisting, and hunting, in the Greater Yellowstone Ecosystem. Grizzlies in the Northern Continental Divide will be next on the chopping block, but that’s for another round with the U.S. Fish and Wildlife.
Despite pleas from environmentalists and Native American Tribes across the West, who maintain the Great Bear is sacred in their histories, the Feds are moving forward fast at the behest of the state politicians.
Arguments on the delisting side say bears are at full capacity in the ecosystem and that is why you see them more frequently in areas near human populations. But according to David Mattson, a leading authority on bear food sources, our bears are just responding to diminishing food sources and moving out beyond the PCA boundaries.
Feds are putting a relisting trigger at 600 or less bears. Their goal is to maintain around 674 bears. At the Spring Interagency Grizzly Bear Management Team, the report was 757 for 2014 as bears are counted when they emerge from their dens. Recently, the official count for 2015 was 714 bears, down 6% from last year. Yet so far in 2015, 59 bears have been killed by mostly human-caused mortalities–either directly or indirectly where the management team has euthanized a bear for food rewards. You can see each bear mortality here and the reasons. That would bring our 2015 count down to 655 for 2015, already below their goal.
One might say rightly that this 2015 spring count minus this year’s mortalities does not account for new births. Yet grizzlies are notoriously slow to expand their population, as I’ve stated in other posts. Since we are most interested in females in the population, grizzlies are not ready to conceive until at least 5 years of age. Their young stay with them for 2.5 years, with a typical litter of 2-3 cubs. And with the high cub mortality, a female grizzly will, at best, only replace herself in 10 years.
If one does the math, it’s easy to see that between hunting (which will be legal but is not now; yet even now with hunter mistakes, several grizzlies are killed every year) and bears killed due to food rewards (either livestock or garbage), it will be very difficult to maintain the Feds goals that would include an official hunt.
In addition, add to this math the food pressures facing grizzlies–loss of Whitebark pines, cutthroat trout, poor berry years–plus the unknowns of climate change and one has a disaster in the making for the Great Bear.
What irks me the most is this statement:
Bears living outside the 19,300-square-mile Yellowstone “monitoring area” would not be counted toward the population goal. Similarly, bears killed outside the monitoring area would not count toward annual bear mortality caps.
This statement delivers the certainty of death for any genetic diversity in the GYE–signaling a slow decline over decades of the bears that are isolated in this ecosystem.
I’ve been interested in what happened to the California Grizzly Bear that made them go extinct so quickly. Interestingly enough, when the Spaniards arrived, they brought their cattle with them. Slowly these herds expanded into the thousands. Because the human population in California was low, few of these cows were used for meat. Mostly they were killed for their hides for leather goods. Monthly, or even weekly, they herded the cattle into killing yards, where they slaughtered and skinned them, leaving the meat to rot. Grizzlies soon learned of these cattle heaps and flocked to them. Grizzly numbers soared during the time when the Spaniards owned California because of easy increased food for bears. But of course the Spaniards had their own forms of cruelty. They roped bears for sport, pitting them against bulls after starving them for days while chained up.
When the United States won the Mexican American war and gold was discovered in California, miners rushed by the thousands into the state. These men were ruthless. They killed anything that got in their way, which included Indians and Grizzlies. Within a short time, twenty years, both of these native populations had almost disappeared completely. Grizzlies became hard to find, until the last lone bear was killed in Southern California in 1908, lured into a beehive trap. It’s a terribly sad story, yet shows how fast this population can decline, from probably over 100,000 bears to almost 0 in twenty to thirty years.
Grizzly bear population in the GYE before delisting had declined to around 125 bears. After over forty years, millions of dollars, herculean efforts by many wildlife biologists and agencies, there are a little over 650-715 bears. Why is the USF&W bowing to political pressures from conservative states and rushing towards a hunt?
