Participatory forestry has been recognized as a tool for improving tropical forest management. The current study assessed the impacts of participatory forest management (PFM) on the structure and regeneration of a mangrove forest at Gazi Bay, Kenya. Data were collected along belt transects
perpendicular to the waterline in both co-managed and state-managed mangrove forests. Basal area and standing density were significantly higher in the co-managed mangrove forests (16 m2/ha and 4 341 tree/ha) as compared to the state forests (eastern block 10.3 m2/ha and
2 673 trees/ha; western block 6.2 m2/ha and 2 436 trees/ha). There were significantly higher (p = 0.0068) densities of merchantable poles in community-managed as compared to state-managed forests. Natural regeneration patterns in community-managed and state-managed forests
were deemed adequate to support the recovery of both forests. The results demonstrate that community participation contributes to improved management of mangrove forests and is in agreement with the principles of sustainable forest management.</jats:p
