Krokosua Squeaking Frog

The Krokosua Squeaking Frog (Arthroleptis krokosua) is a small terrestrial frog known only from the Krokosua Hills Forest Reserve in southwestern Ghana, a locality that lends the species its name. Like other members of the genus Arthroleptis, it is a diminutive, cryptically coloured amphibian adapted to life on the forest floor, where it relies on leaf litter and moist microhabitats for foraging and shelter. Rather than passing through an aquatic tadpole stage, Arthroleptis species typically undergo direct development, with eggs laid in damp substrate hatching directly into miniature froglets, a reproductive strategy that ties the species tightly to consistently humid, undisturbed forest conditions.

The species is classified as Critically Endangered (CR) by the IUCN, reflecting its extremely restricted range, the ongoing degradation of its only known habitat, and a population trend that is decreasing. Krokosua Hills has experienced significant pressure from logging, agricultural encroachment, and forest clearance for subsistence farming, all of which reduce the leaf litter depth and canopy cover this frog depends on for moisture retention and thermal stability. Because the species is not known to occur anywhere else, any further habitat loss within this single reserve poses a direct and severe risk to its survival.

On a more encouraging note, the Krokosua Hills Forest Reserve retains formal protected status under Ghanaian law, and renewed interest from herpetological researchers in documenting West Africa's poorly known Arthroleptis diversity has brought fresh attention to safeguarding this fragile forest fragment. Continued field surveys and reserve enforcement offer a realistic pathway toward stabilising the species' remaining habitat before further decline occurs.

This species inhabits tropical moist lowland and submontane forests in the Eastern Region of Ghana, typically found in leaf litter and low vegetation of primary and secondary forest areas. It occurs at elevations ranging from approximately 200 to 800 meters in the forest zone of the Volta Region.
