Bamboo T-fences are used to restore eroded floodplains and the fine sediment balance as a precondition for natural regeneration of mangroves forests – the latter will then form part of an effective area coastal protection strategy. After successful restoration of sites suitable for mangrove growth, natural regeneration of mangroves will occur. It is, however, essential that the mangroves are protected from human impacts, otherwise the cycle of degradation/destruction and expensive restoration will continue uninterrupted (see illustration under "How do the building blocks interact in the solution?"). This can best be achieved by involving local people in effective protection and management of mangroves through co-management. For more information see solution “Co-management (shared governance) of natural resources in the coastal area”. If rates of natural regeneration are insufficient, supplementary planting of mangroves may be necessary. In such cases, appropriate species need to be planted at the right sites at the correct time.
