From the IUCN Red List Species Account:


Range Description

This species is endemic to the Hottentots Holland and Kogelberg Mountain complexes in South Africa. It occurs up to 1,200 m asl, at 12 locations, and its extent of occurrence is 1,357 km2.

Habitat and Ecology

It inhabits fynbos heathland and does not survive in degraded areas. Breeding is by direct development, and eggs (average expected to be 10 like other members of the genus) are laid in wet vegetation in fynbos seeps and marginally in forest habitats.


This species occurs in small, widely scattered subpopulations (these are currently estimated to be 12). Fire and post-fire impacts on number of mature individuals cause large fluctuations in subpopulation sizes but the species as a whole should be buffered against these fluctuations by the relatively large number of locations.

Population Trend


Major Threats

Even though its habitat is largely protected, the major threats to this species are the spread of alien species (in particular pines) and too frequent and intense fires. Coastal populations are likely to be affected by urban development. However, these threats are believed to be relatively minor.

Conservation Actions

Conservation Actions
No conservation actions are currently prioritised for this species. Much of this species' range is protected in the well-managed Hottentots Holland and Kogelberg Nature Reserves.

Conservation Needed
Results from research need to feed into conservation management plans in affected areas.

Research Needed
Taxonomic revision is still in progress and more work on population status and ongoing threats, such as fire frequency, is required in order to begin monitoring populations trends.

Red List Status

Near Threatened (NT)


Listed as Near Threatened because, although its extent of occurrence and area of occupancy are restricted, it is relatively abundant and the current threats are not perceived to be too severe. However, the extent and quality of its habitat are probably declining, thus making the species close to qualifying for threatened status.

Taxonomic Notes

The taxonomy of A. landdrosia is under revision and is presently best considered complex. The current assessment will be an evaluation of the entire complex.
