Apodolirion macowanii

Taxonomy
Scientific Name
Apodolirion macowanii Baker
Higher Classification
Monocotyledons
Family
AMARYLLIDACEAE
National Status
Status and Criteria
Vulnerable A3c; B1ab(i,ii,iii,iv,v)
Assessment Date

Justification
Known from widely scattered locations between the Fish River valley and Jeffrey's Bay. Of the six known locations, two have already been lost to urban expansion in Port Elizabeth. Two more subpopulations will be severely impacted, with 80% of their individuals and habitat lost due to urban and industrial development, which is planned to take place in the next 10 years at Papiesfontein and Coega. The future loss is estimated to result in a 33% decline.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
Fish River to Jeffrey's Bay.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Humansdorp Shale Renosterveld, Sundays Thicket, Gamtoos Thicket, Great Fish Thicket, Great Fish Noorsveld
Description
Heavy clay soils in renosterveld or valley bushveld.
Threats
Industrial development at Coega is likely to cause the loss of the largest known subpopulation, which is likely to lead to at least a 30% reduction in the population within the next 10 years. Plants at two locations known from historical records are already likely to be extinct due to urban expansion of Port Elizabeth. Subpopulations east of the Kabeljous River are threatened by ongoing habitat loss to further urban expansion. Subpopulations around Grahamstown are threatened by habitat degradation as a result of severe overgrazing.
Population

This species has been seldom collected, and mainly prior to the 1950s. The only population seen was on the farm Slaaikraal outside Grahamstown, where the habitat was very degraded as a result of grazing. The plants are scattered within the distribution over a large area (they are usually solitary). (D. Snijman pers. comm. 2004). It is fairly common at Coega (A.P. Dold, pers. obs.), but this whole subpopulation is likely to be lost to industrial development. It also occurs in a few places around Grahamstown, and towards Fort Brown, and is possibly more common than collections indicate, as the species is cryptic and easily overlooked (A.P. Dold pers. comm.).
