In particular in lowland Europe, the vast majority of these habitats are in an unfavourable conservation status which requires urgent restoration measures. A significant amount of information on the results of previous restorations exists thanks to the implementation of numerous projects and the publication of action plans, technical notes and scientific articles. This information is however very scattered, which does not facilitate the work of practitioners. We therefore propose here a decision support tool using a step-wise framework informed by the successes and failures obtained in two large-scale restoration projects supplemented by scientific and grey literature. This decision tree addresses different restoration techniques depending on the local context, e.g. the intensity of habitat degradation, the richness of soil nutrients, and the presence in the vicinity of a habitat in a good conservation status. Depending on the type of grassland, our tool then suggests various recurrent management techniques to be applied after restoration. This synthetic work is presented step by step according to a dichotomous key which is intended to help practitioners make the right choices in their restoration process."

We posed the questions, can t hese species be restored, and, if so, what role can ex situ plant collections (i.e., botanic gardens, germplasm banks, herbaria) play in the recovery of plant genetic diversity? We reviewed the relevant literature to assess the feasibility of recovering lost plant genetic diversity with using ex situ material and the probability of survival of subsequent translocations. Thirteen attempts to recover species extinct in the wild were found, most of which used material preserved in botanic gardens and seed banks One case of a locally extirpated population was recovered from herbarium material. Eight (60%) of these cases were successful or partially successful translocations of the focal species or population; the other 5 failed or it was too early to determine the outcome. Limiting factors of the use of ex situ source material for the restoration of plant genetic diversity in the wild include the scarcity of source material, low viability and reduced longevity of the material, low genetic variation, lack of evolution (especially for material stored in germplasm banks and herbaria), and socioeconomic factors. However, modern collecting practices present opportunities for plant conservation, such as improved collecting protocols and improved cultivation and storage conditions. Our findings suggest that all types of ex situ collections may contribute effectively to plant species conservation if their use is informed by a thorough understanding of the aforementioned problems. We conclude that the recovery of plant species currently classified as extinct in the wild is not 100% successful, and the possibility of successful reintroduction should not be used to justify insufficient in situ conservation."

A framework to identify constraints to post-extinction recovery of plant species - Application to the case of Bromus bromoideus / Sandrine Godefroid in Journal for Nature Conservation, vol. 54 (Année 2020)

Public [article]  inJournal for Nature Conservation > vol. 54 (Année 2020) . - 125802 Titre : A framework to identify constraints to post-extinction recovery of plant species - Application to the case of Bromus bromoideus Type de document : Livre Auteurs : Sandrine Godefroid, Auteur ; Julien Piqueray, Auteur ; L.-M.

Although most often used to improve the conservation status of endangered species, it can also be considered for species extinct in the wild. The process of resurrecting extinct plant species is however still in its infancy, and it entails additional challenges compared to the reintroduction of locally extinct populations. This study proposes a framework to analyse constraints to post-extinction recovery based on the case of Bromus bromoideus, a species endemic to southern Belgium and northern France, extinct in the wild since 1935. The plant still exists in ex situ collections, and seeds stored for decades at 5% moisture content and -20 °C have shown a good viability. We initiated a feasibility study to assess the risks associated to a programme aiming at reviving this long-extinct species. Several constraints were identified. Biological constraints are related to the fuzzy taxonomy of the species, the unknown origin of the seeds and undocumented ex situ cultivation, and the likely low genetic diversity of the material available for reintroduction. Ecological constraints are linked to the habitat of the species. B. bromoideus has no known natural habitat and is only found in cultivated fields, which are by definition highly anthropized unprotected areas. This study shows the importance of undertaking a preliminary study that addresses all aspects of technical feasibility, scientific justification, biological and societal risks. Based on this exercise and inspired by international standards, we developed a decision tool to assist conservationists to resurrect a plant species in the best possible way."

However, few studies have reported the outcome of reintroduction efforts in plant species. Using data from the literature combined with a questionnaire survey, this paper analyses 249 plant species reintroductions worldwide by assessing the methods used and the results obtained from these reintroduction experiments. The objectives were: (1) to examine how successful plant species reintroductions have been so far in establishing or significantly augmenting viable, self-sustaining populations in nature; (2) to determine the conditions under which we might expect plant species reintroductions to be most successful; (3) to make the results of this survey available for future plant reintroduction trials. Results indicate that survival, flowering and fruiting rates of reintroduced plants are generally quite low (on average 52%, 19% and 16%, respectively). Furthermore, our results show a success rate decline in individual experiments with time. Survival rates reported in the literature are also much higher (78% on average) than those mentioned by survey participants (33% on average). We identified various parameters that positively influence plant reintroduction outcomes, e.g., working in protected sites, using seedlings, increasing the number of reintroduced individuals, mixing material from diverse populations, using transplants from stable source populations, site preparation or management effort and knowledge of the genetic variation of the target species. This study also revealed shortcomings of common experimental designs that greatly limit the interpretation of plant reintroduction studies: (1) insufficient monitoring following reintroduction (usually ceasing after 4 years); (2) inadequate documentation, which is especially acute for reintroductions that are regarded as failures; (3) lack of understanding of the underlying reasons for decline in existing plant populations; (4) overly optimistic evaluation of success based on short-term results; and (5) poorly defined success criteria for reintroduction projects. We therefore conclude that the value of plant reintroductions as a conservation tool could be improved by: (1) an increased focus on species biology; (2) using a higher number of transplants (preferring seedlings rather than seeds); (3) taking better account of seed production and recruitment when assessing the success of reintroductions; (4) a consistent long-term monitoring after reintroduction."

Pre-translocation considerations in rare plant reintroductions: implications for designing protocols / Sandrine Godefroid in Plant ecology, vol. 217, n°2 (Février 2016)

Public [article]  inPlant ecology > vol. 217, n°2 (Février 2016) . - pp. 169-182 Titre : Pre-translocation considerations in rare plant reintroductions: implications for designing protocols Type de document : Livre Auteurs : Sandrine Godefroid, Auteur ; Sarah Le Pajolec, Auteur ; Fabienne Van Rossum, Auteur Année de publication : 2016 Article en page(s) : pp. 169-182 Langues : Anglais Catégories : [Espèces (in biblio)] Arnica montana [Espèces (in biblio)] Campanula glomerata [Espèces (in biblio)] Dianthus deltoides [Espèces (in biblio)] Helichrysum arenarium Mots-clés : plante rare  réintroduction  protocole Résumé : "The existing literature on plant translocations focuses on post-translocation outcome while still overlooking issues related to the preparation phases. Yet, plant translocation programmes face significant pre-translocation challenges. In the present study, we want to share our pre-transplant experience on four rare plant species (Arnica montana, Campanula glomerata, Dianthus deltoides and Helichrysum arenarium), highlighting aspects we need to focus on while planning plant translocations. We emphasize some issues that need to be overcome before any translocation is undertaken during the four steps of translocation preparation, i.e. the selection and profiling of the target species, the seed collection, the development of propagation protocols and the assessment of plant fitness of the populations used as seed source. We discuss the implications of our results for designing translocation protocols. Our findings on A. montana show that if local seed sources are constrained to small remnant populations, seed quality may be poor. Preliminary tests using different kinds of growing medium provided valuable information for optimizing plant propagation protocols. Although it is attractive to establish propagation protocols using seeds obtained via Index Seminum (to avoid wasting collected source seeds), the results obtained were not always reproducible on the seeds collected in the wild source populations. Differences in pre-translocation plant fitness were also detected between seed source populations, which might reflect genetic diversity and maternal effects. As the translocated plants should capture as much genetic diversity as possible to ensure a high adaptive potential and improve establishment success, multisource reintroductions can be recommended."
