Justification
Aloe kraussii is a widespread species (Extent of Occurrence 11 062km²), but has become rare due to extensive habitat loss and degradation. Between five and 10 severely fragmented subpopulations remain on isolated grassland fragments, and therefore this species' Area of Occupancy is estimated to be 20-100 km². It continues to decline due to ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
KwaZulu-Natal
Range
This species is endemic to KwaZulu-Natal province, South Africa, where it occurs between Richmond and Greytown, and eastwards to Durban.
Habitat and Ecology
Major system
Terrestrial
Major habitats
KwaZulu-Natal Sandstone Sourveld, Midlands Mistbelt Grassland, KwaZulu-Natal Highland Thornveld, Moist Coast Hinterland Grassland, Dry Coast Hinterland Grassland
Description
It occurs on grassy slopes.
Threats
This species has become rare due to habitat loss to timber plantations and sugarcane fields. In other areas where it occurs the habitat is degraded by invasive alien species, including eucalypts, black and silver wattles. Around Pietermaritzburg and Durban, many subpopulations known through historical records are now locally extinct due to habitat loss to urban expansion, and loss continues.
Population

This species is unlikely to survive in the long term unless efforts are made to preserve habitat where it is found (Craib 2005). Historical records are from a wide area stretching from Zululand District to Richmond. These records however have imprecise locality description, and many have never been relocated. According to Craib (2005) the plants are now extinct in a number of areas recorded by Reynolds (1969).


Population trend
Decreasing
Notes
Reynolds (1969) considered Aloe krausii to be allied to A. ecklonis. Glen and Hardy (2000) reduced this species to synonymy under A. ecklonis but gave no reasons to their decision (Craib 2005), and therefore the species has been reinstated. A lack of recent records for this species may be due to historical taxonomic confusion.
