Genetic considerations in ecosystem restoration using native tree species. The State of the World's Forest Genetic Resources: thematic study

There is renewed interest in the use of native tree species in ecosystem restoration for their biodiversity benefits. Growing native tree species in production systems (e.g. plantation forests and subsistence agriculture) can also ensure landscape functionality and support for human livelihoods. Achieving full benefits, however, requires consideration of genetic aspects that are often neglected, such as suitability of germplasm to the site, quality and quantity of the genetic pool used and regeneration potential. Understanding the extent and nature of gene flow across fragmented agro-ecosystems is also crucial to successful ecosystem restoration. This study, prepared within the ambit of The State of the World’s Forest Genetic Resources, reviews the role of genetic considerations in a wide range of ecosystem restoration activities involving trees. It evaluates how different approaches take, or could take, genetic aspects into account, thereby leading to the identification and selection of the most appropriate methods. The publication includes a review and syntheses of experience and results; an analysis of successes and failures in various systems; and definitions of best practices including genetic aspects. It also identifies knowledge gaps and needs for further research and development efforts. Its findings, drawn from a range of approaches, help to clarify the role of genetic diversity and will contribute to future developments.
