The Clark’s Nutcrackers are congregating, waiting for the Limber Pine cones to ripen. You can tell they’ve arrived as they are a noisy bunch. As Jays, they are super-intelligent birds. Every year they cache tens of thousands of seeds and are able to memorize the location of their stashes. Clark Nutcrackers have a distinctive ‘wing-whirl’, which is a loud noise they make when flying. Although the pine cones aren’t ready yet, they seem anxious, waiting for just the right moment to steal the seeds away from the waiting red squirrels who also cache the cones for winter food. I’ve been watching the birds eating insects while they while away their time.
This year is not only a bad cone year for White Bark pines, but the Limber Pine cone production is down as well. This bodes poorly for bears. But the good news is that with all the rain we’ve had, the berry crop is up. The chokecherry crop is one of the best in years and I’m waiting with my trail cam for some bears to spend time stripping the berries off the branches before the birds get to them. The bears seem to know the exact time when they’re ripe, and come around for that week only. And with all the beetle kill, the forests are opening up and changing. I’ve seen new understories packed with chokecherry bushes–all full of cherries.
Grizzly bears evolved in the plains. They can’t climb trees like their forest adapted cousins, the black bears, and their massive claws were meant to dig out roots. Pushed from their native habitat into the mountains, they prefer burn areas and meadows, places that emulate their native past. Our mountain forests are rapidly changing with all the downed timber, creating good habitat for the Great Bear.
The little forest next to my house is a perfect example and a fine study area of a rapidly evolving landscape. With seven springs emerging from the limestone base, there is sufficient water ground water. The old growth Englemann Spruce are dead and dying, falling to the ground and leaving large openings where new chokecherry bushes, dogwoods, raspberries, gooseberries, and aspens are rapidly emerging. This is an area we specifically asked the Forest Service NOT to put in their logging plans.
In contrast, the lands adjacent to the springs are private and were logged by the homeowners through the State Forestry Office (who were concerned about fire protective barriers) 5 years ago. Approximately 90% of the trees were cut or were blow downs. This land too has aspens, gooseberries, and grasses–but much of it has a very high ratio, maybe 10:1, of invasives, particularly Canada Thistle. The combination of moisture, sun, and rapid disturbance provided a perfect storm for the invasives. The invasives rob moisture and space for other natives that might get a stronghold. In the non-logged side, the lesson is clear: slower is better and the forest can naturally restore itself with little interference by man.
