Assessment Notes

Justification

Cantharellus afrocibarius is an edible changerelle, only known from woodland in southern Democratic Republic of Congo, and northern Zambia. It is rare in the southern part of its range, but can be fairly common further north. However, ongoing threats to its habitat mean that the species is thought to be in decline. The population size is estimated to fall in the range 2,500-9,999 mature individuals, all of which could be said to be in one subpopulation. Therefore, C. afrocibarius is assessed as Vulnerable under criterion C2a(ii).

Geographic range

This species is only known from Zambia and the Democratic Republic of Congo. The type was collected near Chibuli, Copperbelt Province, Zambia (Buyck et al. 2013), while further collections, and reports of consumption, have come from Haut Katanga Province, Democratic Republic of Congo (De Kesle et al. 2016, 2017).


Population and Trends

The species appears to be rare in the southern part of its range, however, it appears to be “fairly common” further north (see Buyck et al. 2013, De Kesel et al. 2016). Using Dahlberg and Mueller (2011), it may be appropriate to think that in the south of its range each functional individual should be treated as two mature individuals, whereas further north, each should be treated as ten. Also taking into account relative abundance of the species across its distribution, it could be that the species only occurs at a handful more sites in the south of its range (c.25 sites); whereas further north there could be several hundred potential sites for the species (c.250 sites). Overall, based on these figures, the population size would be 2,550 mature individuals. This may still represent an underestimate, but there would require over 1,000 sites in the northern part of the species’ range in order to exceed the thresholds for Vulnerable under criterion C (given the scarcity of the species in the southern part of its range, it is suspected that even if each functional individual was treated as ten mature individuals, this would not have a significant impact on the overall population size).

The species is also thought to be in decline, as even though it may be associated with a range of different woodlands, and species types, ongoing threats to its habitat will be leading to declines.

Habitat and Ecology

The type was collected in Brachystegia woodland, while further collections have occurred in various types of woodland, in particular miombo containing Brachystegia and Julbernardia (De Kesel et al. 2016). It is generally found in older woodland (De Kesel et al. 2016).

Threats

Miombo woodland faces a range of threats, which would likely impact this species because it favours older woodland. The most pressing will be the destruction of this habitat type through logging, in addition to clearance for agriculture (see Jew et al. 2016).

Conservation Actions

Where possible, actions should be taken to protect suitable habitat for this species, including engagement with local stakeholders.

Research needed

Further research is needed to get a clearer estimate of the population size and trend, as well as identifying how widespread the species could be.
