Habitat and Ecology

A. landdrosia inhabits montane fynbos and forest (A.L. de Villiers pers. comm.) along streams and in seepages, including those on steep slopes. It occurs in winter rainfall areas that receive annual rainfall >750 mm. It is found from sea level to 1600 m (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Advertisement Call

This species may be identified by its advertisement call that consists of a relatively long series of strident clicks, unlike the very short, chirping call of the sympatric A. villiersi (Dawood and Channing 2000). Males call from concealed positions in moss and beneath dense vegetation near water along streams (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

IUCN Red List Category and Justification of Conservation Status

Harrison et al. (2001) found that although the limited area of occupancy and extent of occurrence of this species seem to warrant a higher category of threat, major declines are not anticipated because the species occurs in generally rugged and inaccessible terrain, and the known populations are not severely fragmented. The species was therefore classified Near Threatened (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Threats

Harrison et al. (2001) suggest present and potential future threats to this species include changes in the quality of its habitat due to drainage, damming and habitat fragmentation caused by invasive alien vegetation, afforestation and frequent fires (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
