The environments range from alpine area on the higher mountains, to sclerophyll forest and to woodland. Much of the ACT has been cleared for grazing and is also burnt off by bushfires several times per century. The kinds of plants can be grouped into vascular plants, that include gymnosperms, flowering plants, and ferns, as well as bryophytes, lichens, fungi and freshwater algae. Four flowering plants are endemic to the ACT. Several lichens are unique to the territory. Most plants in the ACT are characteristic of the Flora of Australia and include well known plants such as Grevillea, Eucalyptus trees and kangaroo grass.
