Cone collecting may be a hobby for some, but it is serious business for the U.S. Forest Service.
"These trees are a little wispy up top, so you feel movement a lot," he said.
Beauchamp is a professional cone collector. He scales trees of all heights to collect the cones containing precious seeds -- seeds of trees that are now in peril.
"If they are open cones, you don't want them. The seed has already been dispersed," Beauchamp said. "The cones you want are closed, or just starting to push apart."
It's all part of an effort by the U.S. Forest Service to protect Engelmann Spruce Trees, which are now under siege in Colorado from the spruce beetle. Part of the San Isabel National Forest is on the leading edge of the spruce beetle outbreak and foresters said that outbreak is heading north within Colorado.
Those beetles already killed off trees across millions of acres in the state. The U.S. Forest Service says it is the largest outbreak of them ever recorded.
"Almost all of the mature spruce trees, probably within sight of where we are standing, within one to two years, they'll all be dead," said Alex Rudney, who is with the U.S. Forest Service, based at the Salida Ranger District. "A lot of these trees have been infested this year. They'll start next fall and into winter, turn yellow, to brown, to gray -- and the needles will fall off."
That makes collecting seeds from the still living trees so crucial. They're collecting 40 bushels of cones; each bushel contains about 1,200 cones. It sounds like a lot, but not all of the seeds will make it into seedlings, which are needed to preserve the genetic diversity of Engelmann spruce and the forest.
"Trees are like people – they're different," Rudney said. "Each tree has a certain amount of real specific genetic information, that's maybe different than trees from other areas."
Back up in the tree, Robert Beauchamp knows the fruits of his labor today, may not be fully realized until decades from now.
"We're helping keeping the forests going," he said.
Once they are done with the collection, the cones will be taken to the U.S. Forest Service nursery in Nebraska. The seeds will be stored and some will be used to create new seedlings, which can be planted within one to two years.
