Covered with trees. It describes places — a wooded hillside, a wooded valley, a wooded area behind the school — and it means trees are growing there, not a few planted ones but enough to make the place feel like woods. It's an adjective only, so it almost always sits in front of a noun or after 'is': 'the slope is heavily wooded'. It goes naturally with words that say how much: thickly wooded, heavily wooded, densely wooded, or lightly wooded for a thin scattering. You see it most in descriptions of land — travel writing, walking guides, house adverts, novels — rather than in conversation.

樹木叢生的、林木茂密的（形容一塊地方，如 wooded hillside 林木茂密的山坡）。
