Taxonomic notes: We follow Perret (1985) and Rödel et al. (2002) in considering this to be a species distinct from Kassina cochranae.
This species is found in the Upper Guinea Forest block, ranging from southwestern Côte d'Ivoire to southcentral Ghana, though within this general range it is known only from four to five localities. In 2010 is was found in the Yaya classified Forest of the Alépé region in southeast Côte d'Ivoire. It is furthermore known from Taï National Park (2002) and Atewa in Ghana (2006) (N.G. Kouame pers. comm. June 2012). It is also known from Banco National Park in lowland between 500 to 1,000 m asl.
Using the range as a proxy, the extent of occurrence (EOO) is estimated to be 145,482 km2.
Is there information available on the AOO or number of threat defined locations for this species? Also, is there any more detailed information on the elevational range of this species? EJM
It is a species of secondary forest and forest edges, rather than undisturbed primary forest, but it has also been found in primary forest (N.G. Kouame pers. comm. June 2012). It only occurs marginally in heavily degraded former forest (farm bush). It breeds in large swamps and both temporary and permanent water, favouring large, well-vegetated pools.
There have only been a few records, but it is abundant where it has been found. The current population trend and size are unknown (N.G. Kouame pers. comm. June 2012). In 2003-2006, it was not found in Banco National Park, while it was recorded in this area in 1985. However, this national park is very large (3,474 ha) and the species might still be found there (N.G. Kouame pers. comm. June 2012).
It is probably affected by severe deforestation as a result of agricultural expansion (cacao and rubber plantations), logging for wood export, and growing human settlements. Mining is a potential threat in Atewa forest (construction of roads etc.; N.G. Kouame pers. comm. June 2012).
It occurs in Banco National Park and Mont Peko National Park in Côte d'Ivoire, and in Bobiri Forest Reserve and Atewa Forest Reserve in Ghana. More information is needed on this species' distribution, population status, natural history, and threats.
Listed as Vulnerable because its Area of Occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.
According to our records this species may not have been formally reassessed. The current assessment relies on an estimate of the AOO; it would make this a more robust assessment if this could be confirmed with reasoning. To qualify for the VU category, an estimate of the number of threat-defined locations or evidence that the population is severely fragmented (according to the Red List guidelines) is needed. EJM
