Polygala praticola Chodat
Status and Criteria
|H. Mtshali, C.R. Scott-Shaw & L. von Staden|
|EOO 19 466 km², between five and 10 locations continue to decline due to ongoing habitat loss and degradation as a result of too frequent grassland fires, overgrazing, sugarcane and forestry plantations and alien plant invasion.|
|South African endemic|
|Dumisa to Utrecht.|
Habitat and Ecology
|Midlands Mistbelt Grassland, Northern KwaZulu-Natal Moist Grassland, Southern KwaZulu-Natal Moist Grassland, KwaZulu-Natal Sandstone Sourveld, Ngongoni Veld, Wakkerstroom Montane Grassland|
|Highly variable grasslands.|
|This species is probably extinct around Dumisa station (type locality) as this area is excessively transformed by forestry plantations, sugarcane, agriculture and alien invasive plants (C.R. Scott-Shaw pers. comm.). Field observations in areas where it has been recently discovered indicate that habitat degradation due to overgrazing, too frequent fires and alien plant invasion are serious, ongoing threats.|
The distribution range, population size, and number of subpopulations belonging to this species is still somewhat uncertain. The type specimen was collected in southern KwaZulu-Natal, near Dumisa in the Umzinto District, and this is also the only locality listed in the most recent revision of the genus (Paiva 1998). J.A.R. Paiva has however subsequently confirmed that collections from as far north as Utrecht belong to this species. P. praticola is easily confused with P. rodrigueana.
Severe, ongoing threats across its range indicate that the population is likely to continue to decline.
