A nearby remnant of least-disturbed forest should be selected as the “target forest ecosystem” to set restoration goals and to provide a seed source. In the seasonally dry tropics, a regenerant1 density of 3,086/ha is needed to initiate canopy closure within two years. If regenerants are present at higher densities and they are not suppressed by weeds, protection alone can achieve restoration. However, if herbaceous weeds suppress regenerants, protection must be complemented with weeding and/or fertilizer application (assisted natural regeneration, ANR). Where regenerant density < 3,086/ha, protection and ANR must be complemented with tree planting. Where incoming seed dispersal from remnant forest remains possible, only a few “framework tree species” need be planted i.e. representative species of the target forest type that i) survive and grow well on deforested sites, ii) have dense, spreading crowns to shade out weeds and iii) attract seed- dispersing wildlife. Where such seed dispersal is not possible, all tree species of the target forest ecosystem must be planted (maximum diversity methods). Where top soil is lacking, planting “nurse” trees to improve soil structure and nutrient levels (e.g. Ficus & legumes) must precede other restoration procedures. Re-introduction of endemic, endangered or threatened tree species can be included in all of the above techniques. Focusing only on red listed tree species is not particularly useful, since such lists are incomplete and fail to recognize local rarity. Restorationists should ensure that the rarest tree species in the target forest recolonize restoration sites, usually by tree planting. The greatest barrier to the use of rare species in forest restoration is low seed availability. Partnerships between restorationists and botanical gardens and/or seed banks may be crucial to ensure rare species are represented in restoration projects. 1 INTRODUCTION Defining Forest Restoration Tropical forest ecosystem restoration is “directing and accelerating ecological succession towards an indigenous target forest ecosystem of the maximum biomass, structural complexity, biodiversity and ecological functioning that are self-sustainable within climatic and soil limitations”. The definition clearly excludes exotic or domesticated species. It explicitly states four measurable indicators of restoration success. Limits imposed by climate change are implicit. Restoration involves overcoming natural and artificial barriers to succession and driving succession forwards more rapidly than would occur without intervention. The target forest ecosystem should be the nearest remnant of least-disturbed forest, growing under similar topographical and climatic conditions. It is used to set restoration goals, particularly species composition (Elliott et al. 2013). Ensuring that the rarest species, in the target forest, re-colonize restoration sites is one of the
