|Scientific Name:||Bdeogale jacksoni|
|Species Authority:||(Thomas, 1894)|
|Taxonomic Notes:||Jackson's Mongoose was considered a montane isolate of Black-legged Mongoose (Bdeogale nigripes) by Hayman (in Sanderson 1940) and Kingdon (1977), and regarded as a subspecies of Bushy-tailed Mongoose (B. crassicauda) by Allen (1914). It was however recognised as a species on its own by Hollister (1918) and several subsequent authorities, including Coetzee (1977), Kingdon (1997), Wozencraft (2005) and Van Rompaey and Kingdon (2013).|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Assessor(s):||De Luca, W., Rovero, F. & Do Linh San, E.|
|Reviewer(s):||Duckworth, J.W. & Hoffmann, M.|
This species is listed as Near Threatened because it is believed to have undergone a population decline of 20–25% over the last 10 years (a period exceeding three generations, with one generation taken as three years) because of the ongoing loss of habitat in its range; such rates are expected to continue for the next three generations. However, several populations are in protected areas, and the species probably is more widely distributed than currently known. It almost qualifies as Vulnerable under criterion A2c+3c+4c.
|Previously published Red List assessments:|
|Range Description:||This species is known only from central and southern Kenya, southeastern Uganda, and from the Udzungwa Mtns (900 km to the south) in Tanzania (Van Rompaey and Kingdon 2013). The Tanzanian population seems to be highly localised: camera-trapping conducted from 2002 to 2004 at 76 sites throughout the Udzungwa Mountains recorded Jackson’s Mongoose in only five sites in an area of only few km2 within Matundu Forest (De Luca and Rovero 2006). Intriguingly, however, extensive camera-trapping in this forest in 2013–2014 did not reveal the presence of this species again (F. Rovero and R. Havmøller unpublished data). It has been recorded from about 300 m asl to montane elevations in the Aberdare Mtns, Mt Kenya and Mt Elgon up to 3,300 m asl.|

|Population:||There is no reliable information, but it is believed to be rare.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It has been recorded from lowland forest as well as in montane forests and bamboo zones. Kingdon (1997) suggested that the presence of remains of rodents of the genera Dasymus and Otomys in stomachs suggests that it hunts frequently in the thick herbaceous growth around swamps.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||3|
|Use and Trade:||It is unknown whether this species is used as bushmeat.|
|Major Threat(s):||Given its apparent dependence on forest habitat, the main threat to this species is likely to be ongoing forest loss in its range (Van Rompaey and Kingdon 2013).|
|Conservation Actions:||In Kenya, Jackson’s Mongoose is confirmed in the Aberdare N. P. and Mt Kenya N. P., and is also likely to occur in Mt Elgon N. P. (Van Rompaey and Kingdon 2013). In Tanzania, all confirmed localities lie within protected areas, including the Udzungwa Mountains N. P. De Luca and Rovero (2006) recommend full protection of forests adjacent to the Udzungwa Mountains N. P., and that other East African lowland forests (including those near Matundu and Nambiga Forest Reserves) be surveyed for the presence of Jackson’s Mongoose.|
