Listed as Near Threatened as although it would meet requirements for Endangered under criterion B1b(iv,v)c(iii,iv)+2b(iv,v)c(iii,iv) the threats are currently not considered to be sufficiently severe or intense, are not considered likely to occur within two generations, and are being controlled by provincial and local authorities as well as a private nature reserve.
|Previously published Red List assessments:|
|Range Description:||This species is known only from two locations on the slopes of the lower Klienrivier and Babilonstoring Mountains, near Hermanus, in Western Cape Province, South Africa, above 200 m asl and up to 1,100 m asl. Most of its very restricted extent of occurrence (EOO) (17 km² and area of occupancy estimated at 10% of EOO) falls within protected areas.|
Native:South Africa (Western Cape)

|Population:||It occurs in small, widely scattered subpopulations associated with seepages within two locations, one a large mountain range and the other a small mountain range. Fire and post-fire impacts on number of mature individuals are expected to cause large fluctuations in subpopulation sizes (as in other members of this genus) but the species as a whole should be buffered against these fluctuations by the relatively large number of subpopulations within each location if the fires are not severe enough to extirpate the entire location.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:|
This is a species of fynbos heathland, which does not survive in degraded areas. It breeds in wet mossy areas near densely vegetated streams and hillside seepages. It presumably lays its small direct-developing eggs (expected to be 10 like other members of the genus) in moss or similar vegetation.
|Continuing decline in area, extent and/or quality of habitat:||No|
|Use and Trade:||
There are no reports of this species being utilized.
Its habitat is largely protected, although one threat to it is the spread of alien species (in particular pines and hakeas) and too frequent and intense fires which are expected to cause large fluctuations in subpopulation sizes (as in other members of this genus). However, these threats are not considered to be severe or intense but require active management as they will act synergystically.
This species requires monitoring of habitat and populations to achieve ecologically sound fire management once basic information concerning population size and phenology is collected. Removal of alien invasive plant species, already being implemented in some protected areas, should continue across the entire range of this species. It occurs in Babilonstoring, Fernkloof, Maanschynkop and Vogelgat Nature Reserves. The effects of fire on this and other species of Arthroleptella requires research.
