PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA SCROPHULARIALES ACANTHACEAE

Scientific Name: Justicia camerunensis
Species Authority: (Heine) B.J.Pollard

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Darbyshire, I.
Reviewer(s): Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
In Cameroon it has a patchy distribution, being absent from several seemingly suitable areas including the Bakossi Mountains and much of Mt Cameroon. Throughout its range, it is threatened by extensive forest clearance, and many subpopulations have already dissappeared.

Population [top]

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Found in the understorey of closed canopy mid-elevation forest, (600–)900–1,200 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): Throughout its range, it is threatened by extensive forest clearance. The Northwest Province subpopulation is highly threatened as closed-canopy forest is scarce here today; it was noted in the collection of 1975 that the forest patch in which it was found was "now in exploitation by local people with handsaws"; this site is therefore likely to be lost. At Mt Kupe, it was recorded most often above Nyasoso, at around 1,000 m alt., where agricultural encroachment is causing significant losses of forest. Sites around Yaoundé are also likely to have been lost.

Conservation Actions [top]

Conservation Actions: Protection of existing mid-elevation forest is required where possible.
