The European turtle dove is one of the farmland birds that has declined markedly in Europe, leading the IUCN to downgrade its status in 2015 from “Near Threatened” to “Vulnerable”. Knowledge of how habitat factors and agricultural practices influence the turtle dove population is crucial for the conservation of this species through the implementation of targeted measures. Here we investigate how foraging and nesting habitats influence the abundance of turtle doves at national and regional scales, using a 23-year dataset from point counts carried out throughout France, a stronghold country for this species during the breeding season. We found that turtle dove abondance was positively affected by fallow lands, both at national and regional scales. Turtle dove abundance was also negatively affected by fodder crop area at national scale, but the effect was detected in only four of the 13 French regions. We also showed that an increase in hedgerows length had a positive effect on turtle dove abundance. On the other hand, forest edges length showed a bell-shaped trend, suggesting that an increase in forest edges length may have a favourable effect on turtle dove abundance only up to a given threshold. We suggest that targeted conservation measures combining an increase in fallow lands and hedgerows length could allow the stabilisation or even an increase in turtle dove abundance in France, but also in European countries with similar landscapes.

These populations may concurrently be those where the most significant evolutionary changes will occur; those most facing increasing extinction risk; the source of migrants for the colonization of new areas at leading edges; or the source of genetic novelty for reinforcing standing genetic variation in various parts of the range. Deciding which strategy to implement for conserving and sustainably using the genetic resources of peripheral forest tree populations is a challenge. Here, we review the genetic and ecological processes acting on different types of peripheral populations and indicate why these processes may be of general interest for adapting forests and forest management to climate change. We particularly focus on peripheral populations at the rear edge of species distributions where environmental challenges are or will become most acute. We argue that peripheral forest tree populations are “natural laboratories” for resolving priority research questions such as how the complex interaction between demographic processes and natural selection shape local adaptation; and whether genetic adaptation will be sufficient to allow the long-term persistence of species within their current distribution. Peripheral populations are key assets for adaptive forestry which need specific measures for their preservation. The traditionally opposing views which may exist between conservation planning and sustainable forestry need to be reconciled and harmonized for managing peripheral populations. Based on existing knowledge, we suggest approaches and principles which may be used for the management and conservation of these distinctive and valuable populations, to maintain active genetic and ecological processes that have sustained them over time.

Effet de l’exposition sur la richesse et la composition floristique des lisières forestières dans le Gâtinais oriental (Loiret) / Richard Chevalier in Revue forestière française, vol 67 n° 5 (septembre 2015)

La moitié est en exposition fraîche alors que l’autre moitié est en exposition chaude. Un relevé de la flore vasculaire de 400 m2 a été réalisé le long de chaque lisière. Les résultats montrent des différences en termes de richesse spécifique et de composition floristique. La flore des lisières en exposition fraîche est plus sciaphile, hygrophile et forestière que celle des lisières en exposition chaude, plus thermophile, xérophile et typique des milieux agricoles. Ces résultats suggèrent que les lisières en exposition fraîche seraient plus propices à la conservation des espèces sensibles aux changements climatiques et à la fragmentation forestière. Obtenus avec un dispositif pour lequel de nombreux facteurs ont été contrôlés, ces résultats mériteraient d’être confrontés à d’autres contextes de types de lisières pour en valider le caractère générique.

Comparison of tree microhabitat abundance and diversity in the edges and interior of small temperate woodlands / Annie Ouin in Forest ecology and management, vol 340 (March 2015)  

Public [article]  inForest ecology and management > vol 340 (March 2015) . - pp 31 - 39 Titre : Comparison of tree microhabitat abundance and diversity in the edges and interior of small temperate woodlands Type de document : Article/Communication Auteurs : Annie Ouin, Auteur ; Alain Cabanettes, Auteur ; Emilie Andrieu, Auteur ; Marc Deconchat, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 31 - 39 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] composition floristique [Termes IGN] houppier [Termes IGN] lisière [Termes IGN] microhabitat [Termes IGN] structure d'un peuplement forestier [Vedettes matières IGN] Ecologie forestière Résumé : (auteur) Forest edges are important features of wooded farmland. Their role for biodiversity was investigated using tree microhabitats (TMH) as an indirect indicator of forest biodiversity. Because they are managed more intensively, trees in the edges of fragmented temperate woodlands are likely to host more TMH than trees in their interior. In this study, we tested this hypothesis in relation to tree density, diameter, species composition and the structure and management of woodland edges. We selected 28 woodlands with edges differing by their structure and the adjacent fields. Eleven types of TMH were recorded in two transects set up in the edges and interior of the woodlands. TMH density was significantly higher in the woodland edges (4.67 ± 0.78 per 100 m2 area) than in the interior (1.86 ± 0.23 per 100 m2 area). Some TMH - patches of bark loss, cracks, sap runs and epiphytes – were significantly more abundant in the edges than in the interior. These results were accounted for by the convergence of several factors: (i) significantly higher tree density in woodland edges, (ii) a significantly higher proportion of TMH host trees in woodland edges, (iii) a larger tree diameter on average in woodland edges and, even in the same given size class, a higher frequency of TMH host trees, and (iv) greater abundance in woodland edges of tree species more likely to host TMH, even with small diameters. The positive relationship found between the height of the bottom of the crown and TMH abundance may have resulted from abiotic factors (micro-climatic conditions) related to long management rotations, but we did not demonstrate any direct effect of management practices. Given the large number of forest taxa, but also farmland taxa, that depend on TMH, woodland edges should be reconsidered as zones of high potential interest for forest biodiversity conservation.

We recorded 154 vascular species in the study plots, including 3 non-native species. We used generalized linear mixed models to analyze changes in forest structure and plant species composition in relationship to the distance from forest roads. The spatial patterns in stand structure at different distances from roads differed with road age. The large canopy openness on the edge of 3-year-old roads decreased with time after the construction. A progressive decrease in tree height on roadsides was observed after the road construction, suggesting tall trees could not withstand the dry and windy roadside environment. The edge effect on the canopy tended to be larger at higher elevation sites. The spatio-temporal pattern of species occurrence based on distance from roads differed by species. Typical pioneer species such as Schima wallichii and Eurya japonica increased along the edge, while less aggressive pioneer species and understory species decreased. As time passed after the road construction, some climax and understory species decreased at the forest edge, while other climax and understory species increased. The modeling methods proposed in this study could be applied to different roadside and edge study sites.
