Current Rarity Status of the Proteaceae  1990

The status of Red Data Book Proteaceae was reviewed at a workshop held in 1986, shortly after the Red Data Book for Fynbos plants was published. There are too few scientists to keep tabs on all these species: your observations are thus indispensable, your vigilance is essential, and your participation is urgently required!

EXTINCT (X): No longer existing in the wild.

Leucadendron spirale: Collected only four times between 1801-1933, its habitat is now largely under cultivation.

Mimetes stokoei: Known from 1922-1969, there were never more than a dozen plants in two populations. The possibility that pickers reduced the colony prior to 1922 cannot be verified. Perhaps its extinction was natural, but more likely it was wiped out by a Protea orchard (see PAN 8:5).

Sorocephalus tenuifolius: A single population of 700 plants was known in 1980. Went extinct in wild in 1985 when its habitat was ploughed up for an apple orchard. Seven plants were given to Kirstenbosch Botanic Gardens by Nature Conservation Department in 1985. Neglected, by August 1987 they had all died (see PAN 3).

ENDANGERED (E): In immediate danger of extinction if factors causing decline continue operating.

INDETERMINATE (I): A temporary grouping when not enough information is available to put into endangered, vulnerable or critically rare categories, but it is reasonably certain that the species does indeed belong in one of these categories. Further data are needed to determine the status. There are currently no species in this category as rarity in Proteas was recently studied by Sue Tansley - usually this category is the largest.

UNCERTAIN (U): A temporary grouping for unconfirmed reports suggesting inclusion in endangered, vulnerable or critically rare categories.

Pr curvata, laetans

Fa macnaughtonii

NO LONGER THREATENED: No longer included in the above categories due to an increase in population sizes or numbers, or due to the discovery of more populations or more individuals.
