Forests are an essential part of Earth\u2019s operating system. They reduce the buildup of heat-trapping carbon dioxide in the atmosphere from fossil fuel combustion, deforestation and land degradation\u00a0by 30% each year. This slows global temperature increases and the\u00a0resulting changes to the climate. In the U.S., forests take up\u00a012% of the nation\u2019s greenhouse gas emissions<\/a> annually\u00a0and store the carbon long term in trees and soils.<\/p>\n

Mature and old-growth forests, with larger trees<\/a> than younger forests, play an outsized role in accumulating carbon and\u00a0keeping it out of the atmosphere. These forests are especially\u00a0resistant to wildfires and other natural disturbances\u00a0as the climate<\/a> warms.<\/p>\n

Most forests in the continental U.S. have been harvested multiple times. Today, just 3.9% of timberlands across the U.S., in public<\/a> and private hands,\u00a0are over 100 years old, and most of these areas hold relatively little carbon compared with their potential.<\/p>\n

The Biden administration is moving to\u00a0improve protection for old-growth and mature forests\u00a0on<\/a> federal land, which we see as a welcome step. But this involves regulatory changes that will likely take several years to complete. Meanwhile, existing forest management<\/a> plans that allow logging of these important old, large trees remain in place.<\/p>\n

As scientists who have spent decades studying\u00a0forest ecosystems\u00a0and\u00a0the effects of climate change<\/a>, we believe that it is essential to start protecting carbon storage in these forests. In our view, there is ample scientific evidence to justify an immediate moratorium on logging mature and old-growth forests on federal lands<\/a>.<\/p>\n
