616 H. J. Ndangalasi and N. J. Cordeiro
(H.J.Ndangalasi&N.J. Cordeiro,unpubl. data, 2006–2024), we recommend in situ planting of seedlings in Amani Nature Reserve as well as in surrounding forest fragments, to safeguard both species in Tanzania. This process is currently being developed in collaboration with the local management authorities.
