Lachenalia moniliformis W.F.Barker
Status and Criteria
Endangered B1ab(iii,v); C2a(i)
|D. Raimondo, G.D. Duncan & L. von Staden|
|Three small, isolated subpopulations within a limited area (EOO 233 km²) continue to decline due to ongoing habitat loss and degradation. The largest known subpopulation consists of around 100 mature individuals, and the population is estimated to number less than 300 mature individuals.|
|South African endemic|
|Breede River Valley between Worcester, Villiersdorp and Bonnievale.|
Habitat and Ecology
|Breede Shale Renosterveld, Breede Alluvium Renosterveld|
|Dry, stony shale flats and sandy depressions.|
|Less than 50% of this species' habitat remains intact after extensive losses to agricultural expansion, and loss continues. Small fragments continue to be degraded due to grazing, a lack of fire, as well as erosion.|
Until recently, this species was only known from the type locality, where a small subpopulation consisting of around 50 mature individuals is declining due to ongoing habitat loss to vineyard expansion. In 2008 a second subpopulation was found in a road verge between Worcester and Villiersdorp, but the plants were not counted, and a discovery of a third subpopulation of about 100 plants in 2014 significantly expanded the known range of this species, indicating that it may be overlooked elsewhere in the Breede River Valley. Most of this species' habitat has however been converted to vineyards, and only small fragments remain, so that the likelihood of any other large subpopulations exist is small.
