Scientific Name: Acacia negrii
Species Authority: Pic.Serm.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2010-06-21
Assessor(s): Contu, S.
Reviewer(s): Hilton-Taylor, C.
Justification:
The estimated extent of occurrence (EOO= 90,000 km²) doesn't meet the threshold for a threatened category at present. However, due to the severely fragmented distribution (the forested patches are severely scatted in a matrix of agricultural lands) and the fact that the species is not known to occur within the protected areas network, it is believed that the species is of conservation concern and it is therefore rated here as Near Threatened (meets Bab(iii)). Further research and field work should be carried out to study population size and dynamics of this species and make sure it doesn't fall into a threatened category in the near future.

Population [top]

Population: A. negrii has been described as rather common in association with Juniperus procera forest (Dyce and Friis #6189).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: A. negrii is a shrub or tree up to 6 m with a flattened crown which grows in upland wooded grasslands, montane woodland, hilly grassland with scattered Acacias, rocky grazed area with Eucalyptus-stands, open dry hillside in low scrub and in disturbed habitats such as along roadsides. The seeds of A. negrii are very small in relation to pod width.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: The species is used as fuelwood and bee forage.

Threats [top]

Major Threat(s): Deforestation, accelerated soil erosion, and land degradation are serious problems in Ethiopia. The species occurs in the dry evergreen montane forest and grassland habitat which is under severe pressure as a consequence of inhabitants' need for agriculture and grazing land.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures specifically for A. negrii, and the species is not currently known to occur in the protected areas network. Samples of seed of A. negrii are currently stored in the Svalbard Global Seed Vault (Norway) as an ex situ conservation measure. The species has already been assessed as Vulnerable (VU A2cd+B1ab (I,ii,iii,iv)) in the Red List of Endemic Trees and Shrubs of Ethiopia and Eritrea (Vivero et al. 2005).
