Filled with or containing a forest; as much or as many as a forest can hold.
From 'forest' + '-ful' (a suffix meaning 'full of' or 'as much as will fill'), using the standard English word-formation pattern to describe quantity or abundance.
Though uncommon, 'forestful' is a poetic way to express abundance—imagine describing a landscape as 'a forestful of green'—it evokes visual richness more powerfully than simply saying 'forested.'
