Assessment Information [top]

Red List Category & Criteria: Endangered C2a(ii) ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

Reviewer(s): Taylor, J. & Butchart, S.
Facilitator/Compiler(s): Ekstrom, J., Evans, M., Shutes, S., Starkey, M., Symes, A., Taylor, J.
This species has a small and fragmented range, within which its woodland habitat is being cleared for cultivation and being altered by selective tree-cutting, such that its very small population is presumed to be declining (Collar and Stuart 1985). It is therefore listed as Endangered.

Previously published Red List assessments:
2008 Endangered (EN)
2004 Endangered (EN)
2000 Endangered (EN)
1996 Vulnerable (VU)

Geographic Range [top]

Range Description: Ploceus golandi is known only from southeastern Kenya. Most records are from the Arabuko-Sokoke Forest (350 km2 occupied by this species [Bennun and Njoroge 1999]), but it is also recorded from the Dakatcha area near Malindi to the north of the Sabaki river (300 km2  [Bennun and Njoroge 1999]), and from the eastern edge of Galana Ranch east to Marafa and Hadu (Zimmerman et al. 1996). The population was estimated to be not more than 1,000-2,000 pairs in the early 1980s and there has not been a more recent assessment. The species may not breed in Arabuko-Sokoke Forest, since it appears to be largely absent during April-July, reappearing with young in August and thence regularly seen into November, with few records from December-February (Zimmerman et al. 1996). It is believed to have bred north of the Sabaki river in 1994, when many juveniles were observed near Dakatcha in mid-July (Zimmerman et al. 1996).

Population [top]

Population: The population was estimated to be not more than 1,000-2,000 pairs (2,000-4,000 mature individuals) in the early 1980s, and there has not been a more recent assessment. This estimate is roughly equivalent to 3,000-6,000 individuals in total.

Trend Justification:  The population is suspected to be declining at a moderate rate in line with the clearance and degradation of its forest habitat.
Current Population Trend: Decreasing
Additional data:
Number of mature individuals: 2000-4000 Continuing decline of mature individuals: Yes
Extreme fluctuations: No Population severely fragmented: No
No. of subpopulations: 1 Continuing decline in subpopulations: No
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: Yes
No. of individuals in largest subpopulation: 100

Habitat and Ecology [top]

Habitat and Ecology: Outside the Arabuko-Sokoke Forest, the species is confined to lowland Brachystegia woodland (Zimmerman et al. 1996). Within the Arabuko-Sokoke Forest, it has been recorded from all forest habitats, although it is commonest in Brachystegia woodland. Occurs in noisy but somewhat erratic flocks of 5-30 birds and also sometimes observed in mixed species flocks (Fry and Keith 2004). It feeds high up in the canopy on beetles and caterpillars. It presumably nests at low densities in the tops of tall trees, probably in March, with the onset of the rains (Zimmerman et al. 1996).

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 4
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): Clearance of woodland for agriculture is the main threat to the species, e.g. at Dakatcha where hilltops are being extensively cleared for cultivating pineapples, and where woodland is also being damaged by cutting of Brachylaena trees (in great demand for fuelwood and carving-timber) (Bennun and Njoroge 1999). Forest at Arabuko-Sokoke continues to be degraded by both illegal logging and licensed wood removal. There is also some political pressure for degazettement of the Kararacha-Mpendakula section of this forest (Waiyaki and Bennun 1999).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
Arabuko-Sokoke Forest is the focus of a project to promote long-term conservation of the forest through sustainable management and community participation in forest conservation (Fanshawe 1997).

Conservation Actions Proposed
Gazette Dakatcha Forest as a forest reserve or area with similar protected status (Bennun and Njoroge 1999). Enforce legislation controlling forest-use in Arabuko-Sokoke. Better define its habitat and breeding requirements, in particular its tolerance of forest degradation. Census and monitor its population size. Improve knowledge of its distribution. Continue efforts to conserve Arabuko-Sokoke Forest.
