Most tree covered refers to an area that has high forest density and is dominated by trees. This term could be replaced with synonyms such as heavily wooded, forested, treed, sylvan, and arboreal. These words all describe an area covered in an abundance of trees. Each word brings a slightly different connotation to the description. "Heavily wooded" suggests an area with thick, lush forestation, while "forested" can refer to any area with trees, regardless of density. "Treed" implies the presence of individual trees rather than a contiguous forest, whereas "sylvan" and "arboreal" refer more broadly to the natural world of trees and forests.
