The last decade has seen a vigorous debate on whether to use local or nonlocal seed. The use of local seed has been the preferred approach because it is expected to maintain local adaptation and avoid deleterious population effects (e.g., maladaptation and outbreeding depression). However, the impacts of habitat fragmentation and climate change on plant populations have driven the debate on whether the local-is-best standard needs changing. This debate has largely been theoretical in nature, which hampers provenance decision-making. Here, we detail cross-sector priority actions to improve provenance decision-making, including embedding provenance trials into restoration projects; developing dynamic, evidence-based provenance policies; and establishing stronger research–practitioner collaborations to facilitate the adoption of research outcomes. We discuss how to tackle these priority actions in order to help satisfy the restoration sector’s requirement for appropriately provenanced seed.

Seed sourcing for restoration in an era of climate change / Kayri Havens in Natural Areas Journal, 35 (1) (2015) 

Public Citation [article]  inNatural Areas Journal > 35 (1) (2015) . - 122-133 Titre : Seed sourcing for restoration in an era of climate change Type de document : Imprimé Auteurs : Kayri Havens ; Pati Vitt ; Shannon Still ; Andrea T. Kramer ; Jeremie B. Fant ; Katherine Schatz Année de publication : 2015 Article en page(s) : 122-133 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Restauration des écosystèmes [CBNPMP-Thématique] Revégétalisation [CBNPMP-Thématique] Végétal local [LOTERRE-Biodiversité] Changement climatique Résumé : Proper sourcing of seed for ecological restoration has never been straightforward, and it is becoming even more challenging and complex as the climate changes. For decades, restoration practitioners have subscribed to the “local is best” tenet, even if the definition of “local” was often widely divergent between projects. However, given our increasing ability to characterize habitats, and rapid climate change, we can no longer assume that locally sourced seeds are always the best or even an appropriate option. We discuss how plants are responding to changing climates through plasticity, adaptation, and migration, and how this may influence seed sourcing decisions. We recommend focusing on developing adequate supplies of “workhorse” species, undertaking more focused collections in both “bad” years and “bad” sites to maximize the potential to be able to adapt to extreme conditions as well as overall genetic diversity, and increasing seed storage capacity to ensure we have seed available as we continue to conduct research to determine how best to deploy it in a changing climate.

Will the use of less fecund cultivars reduce the invasiveness of perennial plants ? / Tiffany M. Knight in BioScience, 61 (10) (10/2011) 

Public Citation [article]  inBioScience > 61 (10) (10/2011) . - 816-822 Titre : Will the use of less fecund cultivars reduce the invasiveness of perennial plants ? Type de document : Électronique Auteurs : Tiffany M. Knight ; Kayri Havens ; Pati Vitt Année de publication : 2011 Article en page(s) : 816-822 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Thématique] Cultivars, descriptions variétales, essais variétaux, catalogues, types de variétés, identification variétale Résumé : Many invasive species were originally introduced for horticultural purposes, and several continue to be profitable for the green (nursery, horticulture, and landscape) industry. Recently, some plant suppliers have marketed less fecund cultivars of several invasive species, including glossy buckthorn (Frangula alnus), burning bush (Euonymus alatus), and Japanese barberry (Berberis thunbergii), as “safe” alternatives to invasive relatives. We use published matrix population models to simulate the effect of reducing fecundity on the population growth rates of invasive species. We show that large changes in fecundity result in relatively small changes to the population growth rates of long-lived species, which suggests that less fecund cultivars may still provide an invasive threat. Furthermore, many cultivars are clonal selections, and if crossed with other cultivars or selfed, they produce offspring with traits and fecundities that do not resemble the parent plant. On the basis of these two lines of evidence, we suggest that only female sterile cultivars that cannot reproduce asexually should be considered “safe” and noninvasive. Marketing less fecund cultivars as “safe” is premature at this time, and further research is necessary to determine the potential invasiveness of different cultivars.
