Assessor(s)
A.G. Rebelo, H. Mtshali & L. von Staden
Justification
Paranomus dispersus is widespread and common. It is possibly declining in parts of its range due to competition from alien invasive plants, but is not yet in danger of extinction. It is therefore assessed as Least Concern.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Paranomus dispersus has a limited range in the mountains of the central Little Karoo, where it occurs in the Swartberg, Touwsberg, Rooiberg, Langeberg and western Outeniqua Mountains between Barrydale and Oudtshoorn. It also occurs on the Riviersonderend Mountains.

Description
It occurs in sandy places in sandstone fynbos, 200-1400 m. Mature individuals are killed by fires, and only seeds survive. Seeds are released after ripening, and dispersed by ants to their underground nests, where they are protected from predation and fire. It is pollinated by insects.
Threats
In the Riviersonderend and Outeniqua mountains, subpopulations are threatened by competition from alien invasive plants. As a reseeder, P. dispersus is potentially vulnerable to too frequent fires, as local extinctions can occur when fires repeatedly kill individuals before they reach reproductive maturity.
Population

Population structure is variable, sometimes it occurs in dense stands that dominate the veld, but also as isolated plants (Rebelo 2001). It is possibly declining on the southern slopes of the Riviersonderend Mountains and also in the Outeniqua Mountains, but the majority of the population has no severe threats and is therefore inferred to be stable.
