Titre : Plants for Ecological Restoration: A Foundation and a Philosophy for the Future Type de document : Imprimé Auteurs : Terrance D. Booth ; Thomas A. Jones (1942-) Année de publication : 2001 Article en page(s) : 12-20 Langues : Anglais (eng) Résumé : Today’s conservation concerns range from rare plant preservation to landscapes threatened by alien annuals. Effective action follows effective decision-making based on appropriately framed questions. We present the restoration gene pool (RGP) concept as a framework for choosing plant materials based on the priorities of the species, plant communities, systems, and landscapes threatened. We couch our discussion in an acknowledgment of 65 y of national plant materials progress that has evolved with society’s priorities and has maintained a high degree of cooperation among participating entities. The plant materials program and its cooperators have contributed the bulk of the material and technology now used in ecosystem restoration and are our foundation for meeting conservation challenges of the future. Using a discussion of the genetics of native plant materials and 2 conservation challenges, we illustrate how the RGP concept can be used to select plant materials based on their ability to meet priority concerns.

Titre : A restoration practitioner's guide to the restoration gene pool concept Type de document : Imprimé Auteurs : Thomas A. Jones (1942-) ; Thomas A. Monaco Année de publication : 2007 Article en page(s) : 12-19 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Revégétalisation Résumé : Restoration practitioners have long been faced with a dichotomous choice of native versus introduced plant material confounded by a general lack of consensus concerning what constitutes being native. The “restoration gene pool” concept assigns plant materials to one of four restoration gene pools (primary to quaternary) in order of declining genetic correspondence to the target population. Adaptation is decoupled from genetic identity because they often do not correspond, particularly if ecosystem function of the disturbed site has been altered. Because use of plant material with highest genetic identity, that is, the primary restoration gene pool, may not be ultimately successful, material of higher order pools may be substituted. This decision can be made individually for each plant species in the restored plant community in the scientific context that ecosystem management demands. The restoration gene pool concept provides a place for cultivars of native species and noninvasive introduced plant material when use of native-site material is not feasible. The use of metapopulation polycrosses or composites and multiple-origin polycrosses or composites is encouraged as appropriate. The restoration gene pool concept can be implemented as a hierarchical decision-support tool within the larger context of planning seedings.

[CBNPMP-Thématique] Diversité génétiqueRésumé : This paper attempts to explain circumstances under which local may be or may not be best. Natural selection may lead to local adaptation (LA), or it may be constrained by gene flow, founder effects, small population size, genetic drift, and archetype. ‘Specialist’ species display greater LA than ‘generalist’ species. Local genotypes are to a certain extent transient, being a consequence of past historical genetic patterns. Two recent meta-analyses found that while local performance exceeded the performance of a randomly chosen nonlocal population in 71% of comparisons, general adaptation across environments was as frequent as LA. Genotypes for restoration are most likely to be effective if they are adapted to current site conditions. As environmental change accelerates, both globally and locally, exceptions to ‘local is best’ may increase. For these reasons, ‘local is best’ may be better thought of as a testable hypothesis rather than as a general assumption. While either local or nonlocal plant material may be most effective for restoration practice depending on individual circumstances, local material will continue to be the first choice for restoration practitioners whenever this option is feasible and effective.
