What does "brush" mean in the context of a landscape?

In the context of a landscape, brush means dense, low-growing woody vegetation, shrubs, scrub, small trees, and undergrowth that covers an area, often forming thickets that are difficult to walk through. Brush in landscape terminology is similar to underbrush, scrubland, chaparral, or bushland, and refers to wild, often unmanaged vegetation that is not tall forest but is more than grass. For example, a brushy hillside might have scattered oak trees with dense manzanita, sage, and thorny shrubs underneath. In forestry, brush is considered ladder fuel that can carry fire from ground to tree canopy, so brush management is important for fire prevention. In landscaping design, brush can be undesirable if it is weedy or invasive, or desirable if it is native shrubs used for naturalistic planting, habitat, or erosion control. Brush can include plants like sagebrush, mesquite, willow thickets, or blackberry brambles. The term brushland describes a biome dominated by shrubs rather than trees or grassland. So in landscape context, brush means low, dense, woody plant growth that forms the understory or dominates open areas, often requiring clearing for development or managed for ecological benefits like wildlife habitat.
