The act or process of disafforesting; the legal or practical removal of forest designation from land.
From disafforest + -ment (suffix forming nouns indicating state or result). A somewhat archaic term that appears in historical legal documents more than modern ones.
Disafforestment is the rarest of the three '-ment/'-ation/-ness' forms of this word family, showing how English sometimes creates multiple competing noun forms and then gradually abandons the less useful ones.
