Zabaglia 4. A model for integrating the habitat requirements of threatened animal species and the physionomical structure of vegetation of the territory applied to the building of the Ecological Network in Marches region Italy. The extreme difficulty in relating data on the presence, diffusion and dispersion of the populations of middle- and large-sized vertebrates and the heterogeneity of the ecological structure habitat of the territory is evident in the scientific literature. Studies on vegetation have produced very plausible and effective models, and maps of the different vegetation typologies distribution, according to middle-long term variables, which can be well represented by means of cartography.
Furthermore, the variability of the models of animal diffusion and dispersion phylopatry and migration does not allow producing univocal and reliable cartographic representations, except for populations homogeneously distributed in stable and wide natural habitats. However, the millenary anthropic action has generally led in Europe and also in Italy to an increasing fragmentation of the territory and the habitats.

This fact calls into question also the hypotheses on the potential faunistic distribution, which are regrettably widely used with lack of thought. We have wondered how to characterize single animal species, birds in this case, in relation to the use that they make of the habitats in their phenological moments breeding, feeding, resting and migration , which are basic for the survival and conservation of the population.
The goal of this work has been the integration of the wide and reliable information available in the scientific literature on the various species, concerning their reproductive and alimentary habitat and microhabitat selection, and the connection of these data, by means a GIS system, to the real distribution of vegetation represented by phytosociological method , to the real land use and the structural and physionomical features of the whole vegetation typologies of the territory.
Several surveys carried out in on the presence and distribution of the species in SIC and ZPS have allowed to realize a cartographic representation of the real distribution of the species of community interest, and relate it to the change and the variability of the habitats. This methodology also allows also to realize reliable maps of the potential distribution of bird species, because they are connected to the real use of the present habitats and to the specific ecological and ethological features dispersion models included of the various species of the existing community.

Pandolfi 1 , S. Biondi 2. Oddi 23, I Urbino. Using monitoring data and habitat variables to model the distribution of bird species in the Marches region Italy. During the last century several populations of birds in Europe have severely decreased, which has been explained with habitat modifications and common use of intensive agriculture. The often rapid changes of the ecosystems can cause the loss of several animal species even in few years, and the reduction of species diversity is currently considered one of the greatest ecological problems on a worldwide scale.
Therefore, understanding the relations between the habitat variables and the animal communities that use them for breeding, feeding or taking refuge is of the highest importance. In this study we have used the data collected in from monitoring campaignes of 36 bird species: these form a basic knowledge of the species distribution on a regional scale, and have allowed to realize maps elaboration integrating the vegetation physionomy and structure in the study areas, which are all included in SIC and ZPS of the Marches region.
A model of spatial species distribution and of prediction of the suitable habitat for each species has been obtained by means of regression analysis, statistical models and GIS analysis. Maps of the real and potential distribution of each species have been obtained: the species potential presence in every unity is associated with a probability value. Suitable habitat maps for each species have also been realized. This distribution model can be used to locate sites of species potential occurrence for future monitoring , or even habitats which should be especially considered for conservation because ecologically important for the species of interest.
The model may also help to develop plans and management strategies for preserving the functionality of the ecosystems. Allegrezza 1 , S. Giammarchi 1. Furthermore, many interesting species have been recognized: Kobresia myosuroides , not indicated in the Marche region, Anemone narcissiflora , Scorzonera aristata and Trollius europaeus subsp.
Viene presentata una sintesi sulla vegetazione a dominanza di leccio Quercus ilex L. Mapping of the present state of vegetation for the use in nature conservation is a practical and useful application of phytocoenology. Methods of modern phytosociology allow a good scientific evaluation of the biological value of a territory.

In this sense, the main aim of this study is to propose an objective and quantifiable scientific index Potentiality Distance Index, PDI in order to evaluate the distance to the optimum status series head of each territory and therefore its global conservation status. The Index is based on the application and interpretation of the Symphytosociological or Dynamic-Catenal Phytosociological conception.
Thus, taking into account the successional relations of the different types of vegetation and their naturalness indexes is possible to define a formula for evaluating the distance to the series head and therefore to their optimum conservation status. Results proposed in the current study show the Index is objective and universal because the global conservation status of the studied area is in accord with results proposed by other authors for this territory with similar indexes. The Index can provide objective and quantitative information to be applied in land management and nature conservation studies, being a useful tool for the restoration of potential natural vegetation in degraded areas.

Allende, Ancona; email: p. The paper analyses the integration of different methodologies for assessing the grazing value of grasslands, aimed at supporting decisions for their sustainable management, that is, the long term preservation of their productive potential. The attribution of an agronomic value specific index to each species can be used for a preliminary evaluation of their productive potential. It can be also considered a first step in the exploitation of data already available from studies made on grasslands using a range of approaches, among them phytosociological tables.

Phytosociological data were further treated with multivariate analysis procedures. Eight woodland types belonging to Fagetalia sylvaticae 4 , Quercetalia pubescenti-petraeae 3 and Populetalia 1 were identified and characterized synecologically and syntaxonomically.

The microthermic beech woodlands occurring in the upper supra-temperate belt were referred to Ranunculo brutii-Fagetum while the beech woodlands of the lower supratemperate belt were placed in Anemono-Fagetum. Alnus cordata woodland communities interposed between the beech and the oak woodland belts were referred to Asperulo-Alnetum cordatae. Quercus cerris woodlands occurring within the lower supratemperate belt and ranging between and m a. As far as oak woodlands are concerned, the termophilous Quercus cerris woodlands of the hilly and sub-montane belts were considered as a new subassociation of Lathyro digitati-Quercetum cerridis named festucetosum exaltatae whereas Quercus frainetto woodlands mainly developed on sandy substrates were referred to Echinopo siculi-Quercetum frainetto.
Both these associations are to be included in Teucrio siculi-Quercion cerridis alliance and in Ptilostemo-Quercenion cerridis suballiance, as well as the chestnuts coppiced woodland communities. Finally Alnus glutinosa woodlands were referred to Euphorbio-Alnetum glutinosae. Foggi 1 , L. Cartei 1 , L. Pignotti 1 , M.
