This project is dedicated to improving the conservation status and ensuring the long-term survival of Aubregrinia taiensis, a Critically Endangered tree species endemic to Ghana. With only 18 known mature individuals remaining globally, urgent action is required to halt its decline and foster recovery. Illegal mining and logging, agricultural encroachment, and wood harvesting are activities that contribute to the decline of A. taiensis in its habitat. Our primary aim is to enhance the viability of A. taiensis populations through a comprehensive, science-based approach that includes seed propagation, nursery development, habitat restoration, and local community involvement. One of the project’s core activities will be the systematic survey within the project’s landscape to assess and update the population, distribution, and habitat statuses of the species. Additionally, the project will collect and propagate seeds from mature stands. These seeds will be cultivated to raise viable seedlings in nurseries and ex-situ establishments, directly contributing to an increase in species’ population. Furthermore, this project will focus on local capacity building and community involvement through training in species identification, seed collection, nursery management techniques, tree planting and monitoring. These efforts will expand current populations, safeguard species, and inspire local stewardship to prevent the species’ extinction.
