Lachenalia moniliformis

Taxonomy
Scientific Name
Lachenalia moniliformis W.F.Barker
Higher Classification
Monocotyledons
Family
HYACINTHACEAE
National Status
Status and Criteria
Endangered B1ab(iii,v); C2a(i)
Assessment Date
2015/09/21
Assessor(s)
D. Raimondo, G.D. Duncan & L. von Staden
Justification
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.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Breede River Valley between Worcester, Villiersdorp and Bonnievale.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Breede Shale Renosterveld, Breede Alluvium Renosterveld
Description
Dry, stony shale flats and sandy depressions.
Threats
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.
Population

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.
