Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2013
Date Assessed: 2013-03-20
Assessor(s): IUCN SSC East African Plants Red List Authority
Reviewer(s): Hilton-Taylor, C. & Scott, J.A.

As the habitat (near streams in grassland) in the largest part of its distribution area is declining in both extent and quality due to the suppression of regular burning and the discontinuing of grazing; and as one of the other locations is the scene of wholesale conversion to agriculture, we assess this taxon as Endangered.

Geographic Range [top]

Current Population Trend: Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology: near streams in grassland, near stream in open area in forest. Herb to 1 m
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes

Use and Trade [top]

Use and Trade: There is no information on any use or trade.

Threats [top]

Major Threat(s): Most collections are from within Kitulo National Park, where the discontinuing of grazing and the halt of the regular burning is impacting grassland taxa. There is no protection of vegetation within Ndukunduku Forest Reserve. The Bulongwa area is heavily cultivated for wheat; conditions in Msima Stock Farm are unknown.  From these observed threats we are deducting an ongoing decline in quality and extent of suitable habitat, as well as a decline of the EOO.
