“…(2) P. australis is a plant with high colonization potential (Coops and van der Velde 1995;Fér and Hroudová 2009;Sebastián-González et al 2012), and sub-specific strains may even have invasive behaviour out of their original range (i.e. Ward and Jacono 2009), so that generalized protection of the sites of occurrence of this species is unjustified.…”

Multi-species habitat models highlight the key importance of flooded reedbeds for inland wetland birds: implications for management and conservation

Background: Inland wetlands are crucial for biodiversity conservation, especially in highly-urbanized landscapes. In the European Union, many wetlands are included in the EU 'Natura 2000' network, the main tool for biodiversity conservation over the continent, which requires the development of site-specific management plans. Clear and feasible recommendations are necessary to provide site managers with effective tools for the maintenance of biodiversity in these unstable environments. Birds are excellent umbrella species, therefore a management targeted at increasing habitat suitability for focal bird species would likely benefit broader wetland biological communities. Methods: During spring-summer 2017, we collected presence/absence data for 10 bird species of conservation interest at a site scale for 21 Natura 2000 sites. We also carried out a point count survey to detect presence/absence of four reedbed-dwelling species at 75 points. At the site level, we estimated landscape characteristics from regional GISlayers, whereas fine-scaled habitat composition was recorded on the field within a 100 m-buffer around the 75 points. We analysed the effect of the extent of different habitats on species' occurrence probability by means of multi-species binomial multivariate adaptive regression splines (MARS) at both scales. We also run species-specific MARS models to compare their performance with those of multi-species models. Results: At the site scale, the extent of the reedbeds/mires was positively associated with the occurrence of all species of conservation concern. At the point-count scale, reedbed extent positively predicted species' occurrence, but only in presence of patches of clear shallow water. Species-specific MARS models showed qualitatively similar results for some species, but generally were outperformed by multi-species ones. Conclusions: Multi-species MARS models confirmed to be an efficient tool in disclosing species-habitat relationships even for set of species including scarce taxa and when only short-term monitoring data are available. In terms of conservation measures, our findings stress the importance of Phragmites australis reedbed as a key habitat for avian biodiversity, but only when it is flooded and interspersed with scattered patches of open water. The preservation of wide (> 100/150 ha) and flooded reedbeds structured in spots of no less than 2 ha emerges as the main conservation measure for the long-term conservation of the threatened avifauna of inland pre-Alpine wetlands.

“…It is well documented that biomass, density and height of reed culms are adversely affected by increasing salinity and flooding (Hellings & Gallagher, 1992;Batriu et al, 2015). Although hydrology is considered as the most decisive factor for their dispersal, their ability of clonal growth and aggressive rhizomatous spread encourage invasion along the whole elevation gradient of the marsh (Sebastián-González et al, 2012). Two variants of the association Phragmitetum communis are distinguished in Schinias.The first is rich in halophytes (Juncus subulatus, J. heldreichianus, J. maritimus) and colonizes temporarily inundated sites, (Table 12, rels.…”

The vegetation developing on the coastal sand dunes and wetland of Schinias National Park, a Natura 2000 Site, was studied following the Braun-Blanquet method. Vegetation units were delimited using cluster analysis and by applying the fidelity measure; the phi-coefficient was used for the definition of diagnostic species. The vegetation types distinguished (twenty associations, two sub-associations and thirteen communities not assigned formal rank), which belong to 18 alliances, 16 orders and 12 classes, are discussed and presented in phytosociological tables. Among them Mathiolo tricuspidatae-Anthemidetum tomentosae, Pistacio lentisci-Pinetum halepensis pinetosum pineae, Puccinellio festuciformis-Aeluropetum litoralis cressetosum creticae and Tamaricetum tetrandrae are described for the first time. The vegetation types recognized in the study area are linked to twelve EUNIS habitat types, nine of which are related to 13 Annex I habitat types (Directive 92/43/EEC), and one to a habitat type of national interest (72A0). One Annex I habitat type occurring in the study area has scattered presence in the Natura 2000 network in Greece (1420), two are infrequent (2190, 2260), two are rare (2230, 2270) and three are priority habitat types (1150, 2250, 2270).

“…Las especies idiosincrásicas son aquéllas que hacen decrecer el grado de anidamiento (Atmar & Patterson 1993), bien por aparecer en parches pobres donde no se esperan o por estar ausentes en los parches más ricos, desviándose del gradiente ecológico que explica el patrón anidado (Ulrich 2009). Puede deberse a requerimientos ecológicos y aparecer en esos lugares donde las características ambientales lo posibilitan (Florencio et al 2011, Sebastián et al 2012. En este estudio, sin embargo, encontramos tres tipos de especies idiosincrásicas (Anexo II): a) especies muy abundantes en el grupo de rodales, b) especies muy escasas y, c) especies con representación intermedia.…”

Se estudiaron 100 fragmentos dentro de la campiña sevillana en relación a la vegetación de la sierra más cercana con el objetivo de identificar los factores que inciden en la riqueza y distribución de las plantas leñosas en comunidades fragmentadas. Los resultados mostraron que la riqueza de especies aumenta con el área y disminuye con el aislamiento. Los fragmentos presentaron un patrón anidado que estuvo correlacionado principalmente con el área mostrando que procesos de relajación son la causa del empobrecimiento. La capacidad de dispersión de las plantas tuvo importancia en la riqueza y composición de los fragmentos siendo las especies no-ornitócoras las más vulnerables a la fragmentación. Estos fragmentos tienden hacia la matorralización dominadas por especies ornitócorasA hundred vegetation fragments were studied in the countryside of Seville in relation to the vegetation of the nearest Sierra in order to identify factors that influence species richness and distribution of woody plants in fragmented communities. The results showed that species richness increases with the area and decreases with isolation. The fragments presented a nested pattern that was mainly correlated with the area showing that relaxation processes are the cause of impoverishment. The dispersal ability of the plants was important for the species richness and composition of the fragments being the non-ornithochorous species the most vulnerable to fragmentation processes. These fragments tend toward woody encroachment dominated by ornithochorous species
