Description:	In the past, climate has fluctuated with periods of cooler, warmer, drier or wetter weather than at present. Plants have been able to adapt, but widespread, rapid warming could be disastrous for rare trees and shrubs – i.e. those native species that are among an area’s most infrequent and most in need of conservation efforts. Rare plants and rare plant communities often exist as relicts of times past, and have survived locally owing to very particular combinations of environmental conditions.
