Justification
Lachenalia ameliae has an extent of occurrence (EOO) of 17 696 km² and is known from less than 20 locations. It is declining due to ongoing habitat loss and degradation due to agricultural expansion, particularly overgrazing in the Little Karoo, where more than 80% of the habitat is severely grazed. It is listed as Near Threatened.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape, Western Cape
Range
This species is endemic to South Africa, and is found from Tanqua Karoo to Montagu, Barrydale and Calitzdorp.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Western Little Karoo, Tanqua Karoo, Montagu Shale Renosterveld, Matjiesfontein Shale Renosterveld, Swartberg Shale Renosterveld, Kango Limestone Renosterveld, Kango Conglomerate Fynbos
Description
It occurs in red, sandy or stony clay flats or on low mounds, in open places or sheltered under low shrubs.
Threats
Within the Little Karoo, many subpopulations of Lachenalia ameliae remain on small renosterveld fragments, after extensive habitat loss to crop cultivation. At least 80% of the remaining habitat is severely grazed.
Population

This species occurs as scattered individuals within suitable habitat patches. It is adapted to remain dormant during years of drought, and may be easily overlooked.


Population trend
Decreasing
Notes
Recent collections by H.M. Steyn in the Tanqua Karoo significantly extended the known range of this species, which was previously thought to be rare and localised.
