Rare Plants of Victoria

Rarity and Conservation

To be rare is to be valuable. Despite the advice of ecologists and field biologists that the emphasis for conservation should be shifted from individual rare species to that of ecosystems, and from specific threatening processes to those that are wide-ranging, the rare species still holds a pre-eminent position in conservation research and application. International, national and state organisations (both inside and outside of governments) produce lists in which individual species, whose long-term survival may be at risk, hold the most significant position. The best known of these organisations, the International Union for Conservation of Nature (IUCN), has a huge range of projects which target threatening processes, ecosystem management and interaction of human and natural communities. But it is their Red List of Threatened Species which has attracted the most attention and has been embraced by the public.

Victoria has its own list of rare and threatened species but, as with any classification procedure, there is some variation within this general theme. Some species are rare but not considered to be threatened, some are threatened but not particularly rare, some may be rare and threatened but there is debate as to whether they are really distinct enough to be called a species in the first place. The following short list is designed to cover a range of types of rare plants in Victoria with a view to examining some issues concerning their classification.

	A typical rare plant Trochocarpa clarkei is a low, sprawling shrub which often grows near the bases of snow gums in sub-alpine woodland.

[more]		*A rare plant where a botanist lives* Tetratheca stenocarpa is a slender, almost leafless shrub, to 1m tall with sprays of pale purple, pink or white flowers [more]
	*A rare plant common in cultivation* Eucalyptus crenulata is a small, crooked tree with dense blue-green foliage, and rough, fissured bark. [more]		*A rare plant that could be a weed* Trianthema triquetra is a prostrate herb, with small fleshy leaves, tiny white flowers and globular red fruits. [more]
