正文(英文) | USDA Forest Service scientists have published an in-depth study on the value of tree planting as a means of offsetting carbon emissions in the United States. An analysis based on publicly available data from more than 130,000 forested plots in the Forest Service's Forest Inventory & Analysis Program found that fully stocking non-stocked and poorly stocked forests would result in an annual increase of 20 percent in the amount of carbon sequestered by forests. Forests and harvested wood products annually offset the equivalent of more than 14 percent of economy-wide carbon dioxide emissions in the Nation, however, almost 33 million hectares of productive forestland are understocked due to harvesting, natural disturbance, limited seedling availability and the infrastructure necessary to reforest, among other factors. Published by the journal Proceedings of the National Academy of Sciences (PNAS), the study by a team of USDA Forest Service scientists suggests that concentrating tree planting on understocked forest land, particularly in western states, Florida, and the Northeast, may substantially increase carbon sequestration capacity in the United States. "Targeted tree planting on existing productive forestland has the potential to enhance the capacity of forests to provide a multitude of ecosystem services," according to lead author Grant Domke, a research forester with the USDA Forest Service's Northern Research Station. "Our analysis suggests that concentrating plantings on productive areas with the fewest trees has greater potential for enhanced carbon sequestration capacity than distributing the same number of trees over larger areas." The analysis takes into consideration growth, removals and mortality and focuses on productive forestlands available for forest management across all land ownerships. "It is always worthwhile to plant a tree, they have a myriad of benefits wherever they are, but this study delivers sound science on which we can base tree planting efforts on forestland," Domke said.
