, 2011b). An important consideration in achieving the goal of self-sustaining ecosystem restoration is the genetic composition of reproductive material which affects the success of restoration both in the short and the long term. Genetic diversity is positively related not only to the fitness of tree populations (Breed et al., 2012, Reed and Frankham, 2003 and Schaberg et al., 2008) but also to wider

ecosystem functioning and resilience (Elmqvist et al., 2003, Gregorius, 1996, Kettenring et al., 2014, Muller-Starck et al., 2005, Sgrò et al., 2011 and Thompson CSF-1R inhibitor et al., 2010). For example, significantly reduced growth was observed in second and third generation seedlings of Acacia mangium compared to the mother trees originally introduced to Sabah (Malaysia)

from Australia in 1967 which represented genetically reduced sub-samples ( Sim, 1984). Self-sustainability of tree populations depends on adaptive genetic variation, combining the potential for survival and good growth and resistance to changing biotic and abiotic stresses ( Aitken et al., 2008, Dawson et al., 2009, Pautasso, 2009, Schueler et al., 2012 and Tooker and Frank, 2012). Furthermore, the extent of gene flow across landscapes over subsequent generations is important for the successful long-term restoration of ecosystems and tree populations ( Céspedes et al., 2003, Cruz Neto et al., 2014, Navascues and Emerson, 2007 and Ritchie and Krauss, 2012). To our knowledge, the success of restoration in terms of establishing tree populations that are genetically diverse Target Selective Inhibitor Library and appropriate to the restoration site has rarely been rigorously evaluated. In the few studies we found that were aimed at evaluating the appropriateness of germplasm collection practices in restoration efforts, mismatching of germplasm to site conditions (Krishnan et al., 2013, Liu et al.,

2008 and Sinclair et al., 2006), and genetic bottlenecks, were common problems. In the case of genetic bottlenecks, source populations for germplasm collection were either declining (Broadhurst et al., 2006 and Broadhurst, 2011), or if they were large and presumably diverse, collection practices failed to capture Florfenicol this genetic diversity (Burgarella et al., 2007, Kettle et al., 2008, Krishnan et al., 2013, Li et al., 2012, Navascues and Emerson, 2007 and Salas-Leiva et al., 2009). In this paper we review current practices in ecosystem restoration using native tree species, focusing on the influence of genetics on long- and short-term success. We build on a thematic study on genetic considerations in forest ecosystem restoration methods that was developed to support the FAO’s (2014) State of the World’s Forest Genetic Resources report (Bozzano et al., 2014).
