Vegetation is all the plant life covering an area, taken together. Dense vegetation, clear the vegetation, low vegetation.
It is a collective word and has no plural in this sense — you describe vegetation as dense, low or scrubby rather than counting it. Ecologists map vegetation to identify a habitat, because what grows says more about a place than any single species does.
