Assarting
(重定向自Assart)

Assarting is the act of clearing forested lands for use in agriculture or other purposes. In English land law, it was illegal to assart any part of a Royal forest. This was the greatest trespass that could be committed in a forest, being more than a waste: for whereas waste of the forest involves felling trees and shrubs, this vegetation can grow again; assarting involves completely rooting up all trees — the total extirpation of the forested area.
