Mangroves are critical ecosystems given their key role in conserving biodiversity, protecting coastlines from érosion and supporting coastal resources. They may be impacted by oil and gas activities, either directly or indirectly. Restoring them is therefore of prime importance. In the Mahakam Delta (East Kalimantan, Indonesia), oil and gas exploration and production have been conducted for more than 40 years. This industry has operated in a quasi-pristine area barely affected by human activities until the mid 80's. Toward the late 1980's and until 2000, the delta was subject to massive and rapid development of shrimp farming and by 2001, 85% of the delta mangroves were destroyed and most of it replaced by ponds used for aquaculture. By the end of 1990's, shrimp farm productivity in the delta decreased due to a lack of nutrients in ponds and the occurrence of shrimp diseases. Numerous ponds were abandoned in the delta. This economic situation generated social instabilities that could threaten the oil and gas industry in the region. Therefore, in order to better protect mangroves and optimize restoration of damaged areas, Total E&P Indonesie embarked on a mangrove restoration initiative of the Mahakam Delta aimed at understanding and contributing to the restoration processes through both natural recolonization and planting techniques. The general methodology implemented has been to i) describe the land cover using satellite imagery, interpreting aerial photos, conducting field work, and establishing GIS maps, ii) inventory the fauna and flora (including mangroves, birds, mammals, reptiles), iii) monitoring the naturally re-colonized areas, replanted areas and original forest in selected areas. Results show that natural recolonization of a mangrove area can be very quick under certain conditions (subject to availability of seeds and easy access of seeds to the area to be recolonized). But in areas where seeds cannot easily move, or where seed supply is scarce, replanting remains the best option. Social aspects have also to be taken into account given that replanting can promote the local commitment to sustainable environmental conservation.
