FLAGSTAFF – The decision to cut more than 1,300 old-growth trees last summer in an eastern Arizona forest has been criticized for breaking trust with the thinning project’s backers. The rebuke comes at a time when forest management is receiving national attention for its role in preventing catastrophic wildfires, such as those last month in California.
The Forest Service cut the old trees in the Apache-Sitgreaves National Forest for fear of losing more of them to dwarf mistletoe, a parasitic plant. But only 6 percent of the trees sampled were infested, according to data collected by Joe Trudeau with the Center for Biological Diversity and the Four Forests Restoration Initiative.
“The problem on the landscape is not an over abundance of old-growth trees,” Trudeau said. “The problem on the landscape is the density of young, small-diameter trees. So what we need to be doing is focusing forest restoration on the small-diameter trees, and the science supports that unequivocally.”
Interior Secretary Ryan Zinke responded to such complaints in a news conference Nov. 20: “Radical environmental groups would rather burn down the entire forest than cut a single tree.”
The Four Forest Restoration Initiative is a partnership that includes the Forest Service, the Arizona Game & Fish Department and the Grand Canyon Trust. The goal is to restore 2.4 million acres of ponderosa stretching across northern Arizona from the Grand Canyon to the New Mexico line.
The restoration group’s stakeholders had toured the area and later sent a letter to the Apache-Sitgreaves National Forest supervisor, Steve Best, calling the approach to cut down so many large trees a “great concern.”
The Center for Biological Diversity dated some of the harvested trees at 200 to 300 years old, said the letter, which also noted scientific support for retaining old-growth trees because they benefit wildlife habitat, increase genetic diversity and potentially improve fire and climate resiliency.
Best said the Apache-Sitgreaves officials are working on recalibrating to make sure crews are more careful about cutting old trees.
