Quantitatively defining the conservation status of Natura 2000 forest habitats and improving management options for enhancing biodiversity

et al. 2010

The main goal of Natura 2000 network is to guarantee the favourable conservation status of habitats and species ensuring European biodiversity. As a result, certain forest areas have been included in this network listed as 9230-Quercus pyrenaica habitat and 9340-Quercus ilex subsp. rotundifolia forest habitat. These areas were previously used for firewood extraction or livestock grazing and browsing. Nowadays these habitats are coppice forests with asexual regeneration, which is far from the desired conservation status. Traditional timber harvesting plans do not take account of the new objectives required for these Natura sites, which attempt to ensure biodiversity and recreational uses instead of simply focusing on timber production. This paper proposes a flexible methodology (applied to the study area ''Dehesa Boyal'' in Á vila, Spain) for managing Natura 2000 forest sites by stands for sustainable forest management and the new requirements. The methodology has two phases. The first, ''Division of the forest area into stands'', defines homogeneous patches of vegetation distinct in species composition, physiognomic structure and future management. The second, ''Conservation status assessment of stands'', quantifies the conservation status of each previously classified stand considering a series of factors such as: functional health, restoration, floral richness and structure. A total value integrating the conservation status of stands is then calculated for the habitat. Both phases use Geographic Information System tools for managing information and visualizing results. The proposed methodology provides forest managers with a good knowledge of the territory and subsequently enables them to take appropriate conservation measures to maintain biodiversity.

“…Forest management guidelines propose lowintensity thinning on sprouts, \ 35% of the pre-thinning basal area for a period of 15 years (Valbuena-Carabana et al 2008). It is worth investing money in these treatments to reach favourable conservation status in the different types of stands, and to ensure probable future acorn regeneration.…”

“…Whereas no comprehensive review exists to our knowledge, gene diversity values found in angiosperm woody species typically ranged from 0.70 to 0.80 (e.g. Fagaceae, VALBUENA-CARABANA et al, 2008;Rosaceae, FARWIG et al, 2008;Leguminosae, LACERDA et al, 2008). More generally, habitat fragmentation is associated with a reduction of genetic diversity within populations (KAWATA, 1997).…”

Population Genetic Structure of Laurus nobilis L. Inferred From Transferred Nuclear Microsatellites

et al. 2009

Species with fragmented populations and low population size often display low within-population genetic diversity and strong among-population differentiation. Laurus nobilis L. (Lauraceae), common laurel, has a scattered distribution throughout the Mediterranean, with only few autochthonous populations. Our goal was to elucidate if this species has range-wide genetic structure and if planted material can be traced back to its origin. Genetic diversity was investigated using 4 polymorphic nuclear microsatellites (nSSR) transferred from two species of Lauraceae. Sixty-six laurel trees were selected from 7 widely separated populations within the Mediterranean distribution area of the species. A total of 34 alleles (9 alleles per locus on average) were found. Mean genetic diversity within-population (H s ), was 0.558. Genetic differentiation among populations (G ST = 0.243) was high compared to that of other angiosperms. Laurus nobilis can be separated into two main gene pools, one from western (Tunisia, Algeria and France) and the other from eastern Mediterranean (Turkey). The Algerian, Tunisian and French populations presented a strong genetic similarity, compatible with the fact that North African laurel populations could be recently introduced from north-western Mediterranean stock.

“…Many of these Quercus pyrenaica habitats have a vital uneven aged forest with several complex covers (each of them with a large number of typical species) and some gaps. On the other hand, successional states involves acorn production and sexual regeneration which lead to different canopy layers with different age classes (Valbuena-Carabana, Gonzalez-Martinez, & Gil 2008). To achieve this scenario, silviculture resulting in conversion into high forest is mostly proposed (Ciancio & Nocentini 2004;Montoya 1982;Serrada et al 2008).…”
