Mr Red said (back in June)So how many names for wooded valleys are there

    bosk
    brushwood
    coppice
    thicket
    boscage
    clump
    underbrush
    brake
    brushwood
    bush
    chaparral
    coppice
    covert
    grove
    wood
    spinny
"
I'm not convinced that all of those words imply valleys. Coppice is a way of managing woodland. I thought a covert was cover for game. And wood, spinney and grove just suggest trees to me.
