As there's a lot of interesting stuff here, I'll just quote a bit (omitting footnotes, text in brackets is my own). First of all, to clarify what a medieval "forest" was:
‘Forest’ in medieval England denoted a defined area of unenclosed land within which wild game, principally deer, along with wide swathes of its habitat were protected by forest laws for the benefit of the king. Medieval forests, however, could include “not only woodland, but also heath, pasture, meadow, and arable land, and even hamlets, villages, and townships.” Importantly, forest jurisdictions in England unlike those in Normandy could, and often did, extend outside the king’s own demesne land (the crown’s landed estate) onto privately held lands, acting as a type of economically restrictive land-use overlay on areas that remained subject to the common law as well.
