The word of the day is bosky:

[after It. boscoso.]

Consisting of or covered with bushes or underwood; full of thickets, bushy. (Also transf.) (OED)

"If further pressed, they may acknowledge that the area's boskiness is largely the result of city planning. The stands of live oaks, valley oaks, pines, redwoods, and mulberries are all as artificial as Lake Cascade, which was created in the nineteen-twenties to irrigate the local golf course. The trees in this former grassland arrived with the houses, and kept on arriving."
