This species is more common than previously thought. However, while not dependent on primary forest, the species's forest-edge habitat is at risk from clearance for subsistence agriculture in part of its small, fragmented range. It therefore qualifies as Vulnerable.

|Range Description:||Ploceus bannermani occurs in western Cameroon (chiefly in the Bamenda Highlands, notably at Mt Oku, also Mt Tchabal Mbabo on the Adamawa Plateau) and eastern Nigeria (on the Obudu and Mambilla Plateaux, where 12-40 were seen per day in 1988). In 1999, it was found to be common in suitable habitat on the crater of Mt Manenguba, south-west Cameroon (Dowsett-Lemaire and Dowsett 1999c) and, in 1998, rare or local at Kodmin in the nearby Bakossi Mountains, this latter representing a small range-extension to the south-west (Dowsett-Lemaire and Dowsett 1998d). In Mendongbuo (Big Babanki, Cameroon) montane area it is fairly common, having been recorded at 22 of 50 counting points (Reif et al. 2006, Hořák et al. 2009).|

|Population:||The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.|
Trend Justification: The species's population is suspected to be declining in line with the clearance and degradation of forest within its range. The likely rate of decline, however, has not been estimated.
|Current Population Trend:||Decreasing|
