The Guinean Forest Biome of West Africa is known to support high species endemism in a wide range of taxa and offer many services to humans and animals. Unfortunately, this ecosystem has continued to be degraded causing a decline in the populations of species and threatening ecosystem provisioning. To conserve these ecosystems, it is necessary to protect large frugivorous species such as hornbills and parrots that contribute to maintain ecosystem services. Hornbills play a crucial role in seed dispersal and are excellent indicators of environmental degradation. Unfortunately, large forest hornbills are threatened by habitat loss and harvesting for traditional belief-based systems. For example, the Yellow-casqued hornbill (YCH) was classified as Near Threatened in 2004 but, 12 years later, is now classified as Vulnerable by the IUCN Red List category. This huge decline is largely attributed to threats from hunting, logging, and wood gathering for firewood. In addition, the Yellow-casqued Hornbill is known to nest in the natural cavities of tall and old trees; therefore, unavailability of suitable nesting sites could be another threat to the species, also suggesting the need for conservation education and activities that will involve different stakeholders (researchers, community and government agencies) towards conserving the species.
