Big trees are a big deal. Preservation of old-growth trees is becoming a contentious battle nationwide.

Trees don't seem controversial, but they are. "The fight over the future of the last old and mature forests in America intensified Tuesday when the Biden administration called for preservation of old-growth trees," reports  Lynda V. Mapes of The Seattle Times. "The administration, after creating an inventory of the nation's old growth, wants to amend 128 forest land-management plans to conserve and steward 25 million acres of old-growth forests and 68 million acres of mature forest across the national forest system."

"For the Pacific Northwest — home to much of the nation's remaining old forests — an effort is already underway to overhaul and update key old-growth protections in the Northwest Forest Plan of 1994, one of the world's most ambitious conservation plans," Mapes writes. "But the nationwide attention from the federal government is adding to the debate over old forests' cultural and ecological significance and their ability to suck up carbon from the atmosphere that is warming the planet."

Not everyone agrees the new initiative is needed. The American Forest Resource Council, a trade group, "panned the old-growth initiative as unnecessary and burdensome," Mapes explains. Council President Travis Joseph issued a statement, saying, "Existing federal environmental laws and forest plans provide direction on managing and protecting old growth. Yet the agency is now being directed to embark on a new, massive bureaucratic process — during a wildfire and forest health crisis — that will likely make forest management more complex, costly, and contentious."

Big trees are a big deal. "They are the most important helpers in absorbing carbon because while they are slower growing than young trees, their greater mass locks away more carbon," Mapes reports. "Recent research shows large trees dominate carbon storage in the Pacific Northwest. Old and mature natural forests also provide a haven for biodiversity and human well-being."

As part of the Northwest Forest Plan overhaul, a 21-member committee "began work last September on updates to reflect changed conditions and new science." The U.S. Forest Service has announced its intent to prepare an environmental impact statement, expected in June, on the Northwest Forest Plan amendment, with a 90-day public comment period to begin at that time.
