{{main|Forest management|Sustainable forest management}}

The management of forests is often referred to as [[forestry]]. Forest management]] has changed considerably over the last few centuries, with rapid changes from the 1980s onward, culminating in a practice now referred to as [[''sustainable forest management]]''. Forest ecologists concentrate on forest patterns and processes, usually with the aim of elucidating cause-and-effect relationships. [[Forester]]s who practice sustainable forest management focus on the integration of ecological, social, and economic values, often in [[Stakeholder engagement|consultation with local communities and other stakeholders]].

In the United States, most forests have historically been affected by humans to some degree, though in recent years improved [[forestry]] practices have helped regulate or moderate large-scale impacts. The [[United States Forest Service]] estimated a net loss of about {{convert|2|e6ha|abbr=off}} 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. 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.<ref>{{cite web|url=http://www.wildrockiesalliance.org/issues/wildfire/enn.html|archive-url=https://web.archive.org/web/20130509225620/http://www.wildrockiesalliance.org/issues/wildfire/enn.html|archive-date=9 May 2013 |title=Wildfires Ignite Forest Management Debate |publisher=Wildrockiesalliance.org |access-date=3 July 2013}}</ref><ref>{{cite book|first=Emily K.|last=Brock|title=Money Trees: The Douglas Fir and American Forestry, 1900–1944|publisher=Oregon State University Press|year=2015}}</ref>
