Moraea australis (Goldblatt) Goldblatt
|Gynandriris australis Goldblatt|
Status and Criteria
Near Threatened B1b(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)
|C. Logie, L. von Staden & D. van der Colff|
|Moraea australis has a narrow coastal distribution range (EOO 3348 km² and AOO <1284 km ²). An estimated 17-20 locations continue to decline due to ongoing habitat loss to coastal development, as well as competition from alien invasive plants.|
|South African endemic|
|Eastern Cape, Western Cape|
|Mossel Bay to Port Elizabeth.|
Habitat and Ecology
|Algoa Dune Strandveld, Groot Brak Dune Strandveld, Southern Cape Dune Fynbos|
|Moraea australis is threatened by ongoing habitat loss to coastal development across its range (land cover data indicates that >52% of its habitat is already transformed). In the Cape St Francis area, plants are now largely confined to road verges, after most of its habitat has been lost to coastal development. There is ongoing disturbance of these roadside areas, particularly due to mowing, but Moraea australis appears to be fairly resilient to disturbance (C. Logie pers. obs.). A subpopulation near the Nelson Mandela Metropolitan University campus in Port Elizabeth is threatened by competition from alien invasive plants.|
This species was rarely collected in the past, and was known from only a few, scattered collections along the southern Cape coast. Recent field observations indicate that it is still fairly common around Cape St. Francis, where large numbers of plants persist mainly in road verges, forming one large, continuous subpopulation. These observations suggest that it is quite likely under-sampled, and much more common than the few historical collections suggest. The population however continues to decline due to ongoing habitat loss.
