(i) The ecology and management of natural evergreen forest and deciduous woodlands of Africa, and development of sustainable resource use management systems for timber, non-timber and non-wood forest products from these vegetation systems, based on the regeneration ecology of these systems and targeted species;
(ii) Rehabilitation of degraded systems, including rehabilitation after mining, and through invader plant stands as pioneer stands towards forest recovery. I have been doing this all over Africa.
