Lachenalia congesta W.F.Barker
Status and Criteria
|A range-restricted endemic to the Roggeveld Escarpment (EOO 1633 km²), and known from nine locations. It is declining due to ongoing habitat loss and degradation.|
|South African endemic|
|Roggeveld Escarpment, from west of Middelpos to Sutherland and Komsberg.|
Habitat and Ecology
|Roggeveld Shale Renosterveld, Roggeveld Karoo, Nieuwoudtville-Roggeveld Dolerite Renosterveld|
|Seasonally moist flats, steeply rolling east-facing mountain slopes and summit ridges in shale gravel or heavy gravelly clay.|
|Lachenalia congesta is threatened by ongoing habitat loss and degradation. Overstocking of rangelands is causing degradation due to overgrazing and trampling. A number of subpopulations occur at sites which have been badly overgrazed. There is also ongoing habitat loss to crop cultivation, but at this stage crop cultivation is only effecting a small proportion of the population (estimated <5%).|
