Scrub country
That's a very original, fitting answer for a non-specific question. It made me laugh, thanks. May I offer the following that the person may fit his situation.
Depending on the land mass by your description of "area":
1. It could be a garden if the shrubs are flowering shrubs and the trees were ornamental or fruit bearing.
2. If the trees are a mixture, that is not of any species of wood for harvesting, and the shrubs are whatever grew and are not cared for, this would best be described as woodland or simply woods. Woods are usually part of farmland in the Midwest or of un-tillable land, sometimes of wetlands.
3. Larger land masses are woodlands or forests, usually having timber and shrubs. Shrubs may be flowering or seedlings that will grow into timber.
4. My grandfather has seen jungles and rain forests in Vietnam with triple canopies of abundant trees and shrubs, vines, plants, grass and weeds. Within these forests one could find clearings for roads, villages and small farms. The vastness of these wooded areas are opposite of our Midwestern states where there are more farmland than woodland.

An area with tall grasses and scattered trees is known in Africa as the savanna.
