Abstract
ABSTRACT Sustainable management of mangrove resources requires monitoring of status and conditions of the forest over time. This study assessed structure and regeneration of mangroves across five mangrove management blocks in Lamu, Kenya. Using stratified random sampling strategy, mangroves were sampled in 152 square plots of 400 m2 along belt transects established perpendicular to the shoreline. Linear regeneration sampling (LRS) was employed to assess composition and patterns of natural regeneration. Six mangrove species were encountered during this study. Based on importance value index, the dominant mangrove species in Lamu are Rhizophora mucronata and Ceriops tagal. At least 42% of the forest is stocked with low-quality poles, an indicator of prolonged human pressure. However, natural regeneration rate of 7,342 ± 450 juveniles ha−1 observed in the forest is considered adequate to support forest recovery after disturbance. The findings of the study have direct applications in the development of harvest plans for mangroves in Lamu.
