Forest transition curve
The change in forest cover over time as the value of land uses changes relative to the competing uses, usually resulting in rapidly decreasing forest area during early industrialization and development, followed by slow expansion of forest area to lower than original levels.

The FRA definition covers very different types of forests. [...] Delimitations among these types are not always clear cut as they exist on a continuum of management intensity along the forest transition curve.
