Page "Forest" Paragraph 80

In the United States, most forests have historically been affected by humans to some degree, though in recent years improved forestry practices has helped regulate or moderate large scale or severe impacts.

However, the United States Forest Service estimates a net loss of about 2 million hectares ( 4, 942, 000 acres ) between 1997 and 2020 ; this estimate includes conversion of forest land to other uses, including urban and suburban development, as well as afforestation and natural reversion of abandoned crop and pasture land to forest.

However, in many areas of the United States, the area of forest is stable or increasing, particularly in many northern states.

The opposite problem from flooding has plagued national forests, with loggers complaining that a lack of thinning and proper forest management has resulted in large forest fires.
