Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA GERANIALES BALSAMINACEAE

Scientific Name: Impatiens frithii
Species Authority: Cheek

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2014
Date Assessed: 2011-03-25
Assessor(s): Cheek, M.
Reviewer(s): Onana, J.-M.
Facilitator/Compiler(s): Lopez Poveda, L.
Justification:
First referred to as Impatiens sp. nov. 1 and assessed as Vulnerable D2 (Cable and Cheek 1998: xliv), the species was formally named in 2002 (Cheek and Csiba 2002). The slender, hairpin-shaped flowers of this epiphytic species are flame-red. They are produced in the wet season from stems often only 15 cm long which scramble along mossy branches of low trees and shrubs. Impatiens frithii is here reassessed as Endangered as it has a small area of occupancy (24 km²), is known from only four broad but very fragmented (100 km intervals) locations (includes the new location at Ebo) and there is continuing decline due to current and future loss of habitat. The assessment in Cheek et al. (2004) is maintained despite the addition of a new location. The extent of occurrence is estimated to be 6,856 km².
History:
2004 Endangered

Population:

Population size is not known but is thought to be in decline.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: An epiphyte found growing in moss forest; (800-)1,100-1,700 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): The species is threatened due to habitat loss by planned plantation expansion (Mt Etinde) and a reservoir scheme (Bakossi Mts).

Conservation Actions [top]

Conservation Actions: Monitoring of the plants in the summit area of Mt. Etinde is advisable. Protection of forest above Njonji should be considered if the record site for this species is to survive. Cultivation at Limbe Botanic Garden is likely to prove difficult due to the altitudinal disparity. A detailed study of this species at Kodmin-Edib where the species is most secure and where conservation efforts might be focused, would provide more precise data on population density and demography, as well as assisting in the placement of future development schemes. Botanical surveys in other parts of the Bakossi Mts, or Rumpi Hills, might discover more sites which would reduce the threat assessment of this taxon.
