Mangrove transformation in the Incomati Estuary, Maputo Bay, Mozambique
The mangroves around Maputo city in Maputo Bay were studied to assess changes in forest cover area and the effect of cutting pressure on the forest structure and conservation condition, by using GIS techniques and ground-truthing. On site, the forest was classified into semi-intact (predominantly intact trees), degraded (with many cut trees), degraded with reed invasion, dwarf mangrove, and new mangrove area. The results showed a 5% increase in forest area in 2003 as compared to 1991, with 64% of the total forest consisting of degraded mangroves. Deforestation took place at a mean rate of 17 ha year-1 between 1991 and 2003.

By identifying the most critical areas of the Incomati Estuary and describing forest condition, this study shows the poor condition of peri-urban mangroves at locations such as this in eastern Africa, and highlights the need for further understanding of estuary regimes that may influence mangrove community changes, other that deforestation.
