Book excerpt: Case studies and experiences with natural regeneration from the region have shown that natural regeneration significantly reduces the cost of restoration in areas that meet certain conditions. Native species that are adapted to the prevailing conditions re-establish on their own with some assistance, achieving accelerated growth in accordance with natural succession, leading to the recovery of native ecosystems. Restoration strategies based on natural regeneration also provide low-cost opportunities for conserving biodiversity and enhancing ecosystem services, including carbon sequestration and watershed protection. This manual describes procedures from almost 20 years of FAO experience with assisted natural regeneration (ANR) in the Philippines and more recently in Indonesia, Cambodia and Lao PDR. In each of these countries, the method was applied for different objectives and convincingly validated ANR’s cost effectiveness. There is an increasing recognition of the benefits and advantages of ANR in light of the ambitious global, regional and national forest restoration targets, and there are considerable opportunities to expand the application of ANR through various restoration related initiatives. It is hoped that this manual can serve as a field reference in guiding the application of ANR for forest restoration.
