Assessment Rationale

Cephalaria foliosa has a restricted distribution, with an estimated extent of occurrence of 2,340.568 km2 and an area of occupancy of 28 km2.  There is an ongoing threat of habitat degradation or destruction from overgrazing by livestock.  Based on this, it has been assessed as Vulnerable, under Criteria B1 and B2.

Distribution

Geographic Range

This species is known from the Eswatini highveld as well as from to localities in South Africa in northern KwaZulu Natal.

Area of Occupancy (AOO)

Estimated area of occupancy (AOO) - in km2Justification
28The estimated area of occupancy has been based on records being from seven localities, calculated using GeoCAT (Bachman et al. 2011), with the standard 2x2 km grid cell being applied.
Continuing decline in area of occupancy (AOO)QualifierJustification
YesInferredIt is possible that this species is declining due to habitat degradation, with overgrazing likely to be having an impact on unprotected wetland systems in the Eswatini highveld.
Extreme fluctuations in area of occupancy (AOO)Justification

Locations Information

Number of LocationsJustification
7This plant has been recorded from 7 localities. These localities are well separated geographically, and are considered to form 7 locations.
Continuing decline in number of locationsQualifierJustification
Unknown-The continued presence of this species has not been confirmed for a number of years, the most recent record from Eswatini being from 1976.

Very restricted AOO or number of locations (triggers VU D2)

Very restricted in area of occupancy (AOO) and/or # of locationsJustification
NoThe estimated area of occupancy for this species based on records from seven localities is 28 km2. This might be an overestimate due to habitat requirements for this species.

Important Conservation Actions Needed

Conservation ActionsNote
1.2. Land/water protection -> Resource & habitat protectionThere is a need for conservation of highveld vlei systems, most of these within Eswatini currently being subjected to heavy grazing.
3.4.2. Species management -> Ex-situ conservation -> Genome resource bankNo material has yet been collected of this species for ex-situ conservation.

Research Needed

ResearchNote
1.2. Research -> Population size, distribution & trendsThere is a need for fieldwork to determine the extent of the population and its trends.
1.3. Research -> Life history & ecologyMore information on this plant's life history and ecology would assist with conservation planning.
