The effects of clearcutting on soil nutrient content were not examined in this study. [29] More recently, forest managers have found that clearcutting oak stands helps regenerate oak forests in areas of poor soil. The tree canopies in oak forests often shade out the ground, making it impossible for newly sprouted oaks to grow.
The forest resources of the United States remained relatively constant through the 20th century. [3] The Forest Service reported total forestation as 766,000,000 acres (3,100,000 km 2) in 2012. [4] [5] [3] A 2017 study estimated 3 percent loss of forest between 1992 and 2001. [6]
Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or negative, depending on whether gains exceed losses, or vice versa.

The cumulative climate impact of logging on our national forests is huge: Between 1984-2021, the Forest Service authorized the logging of 428,531 acres of forest per year on average, contributing ...
Deforestation, particularly in large swaths of the Amazon, where nearly 20% of the rainforest has been clear cut, has climactic effects and effects on water sources as well as on the soil. [32] [33] Moreover, the type of land usage after deforestation also produces varied results.
Clear cut in the Gordon River Valley near Port Renfrew, BC. British Columbia is one of the world's largest exporters of wood fibre. [19] In 2015 it was reported that British Columbia forestry supports 145,800 jobs and 7000 businesses, with an annual revenue of 15.7 billion dollars. [19]
Salvage logging is the practice of logging trees in forest areas that have been damaged by wildfire, flood, severe wind, disease, insect infestation, or other natural disturbance in order to recover economic value that would otherwise be lost.
