Analisi dei cambiamenti dell’uso del suolo nei siti Natura 2000 “Bosco S. Adriano” e “Vendicari”
2008
Population and the economic activities increases, are the main and most important causes of the impoverishment of land and marine ecosystems of the planet. Within this context, the land use and vegetation cover data, and those on the transition between the different land use categories, are among the most required information necessary for the individuation of the sustainable management strategies of environmental and landscape resources. The same information is also necessary to control the efficacy of the environmental politics and the environmental integration instances of specific field politics (agriculture, industry, tourism, ect). In fact, one of the main themes is landscape transfor…
Trasformazioni del paesaggio e conservazione degli habitat nella zona umida di Vendicari (Sicilia)
2009
Il sito Natura 2000 “Vendicari” (ITA090002) si colloca in un più ampio sistema di zone umide costiere della Sicilia Sud-orientale. La particolarità di questi ambienti è legata alla presenza di lagune costiere e di formazioni vegetali che generalmente si trovano a contatto con esse. Questi ambienti costituiscono l’habitat per diverse specie, nonché esclusivi punti di sosta per molti uccelli migratori. Queste aree, un tempo più estese in Sicilia, durante il secolo scorso sono state sottoposte a disturbi e trasformazioni ambientali e paesaggistiche con conseguente riduzione della biodiversità. Le cause che hanno determinato maggiormente tali trasformazioni sono legate allo sfruttamento agricol…
Inventario e monitoraggio delle risorse forestali del sito Natura 2000 “Bosco di S. Adriano”
2008
The WP5 (Action 5.4) of the ManagMED project foresees measurement, evaluation, and estimation of the parameters that have a negative impact on the sites, throughout the use of innovative inventory methods (A5.4). The preliminary studies (WP2) carried out on the chosen Nature 2000 sites, contributed in recognising phenomena and activities which have a negative impact on the protection state of the sites. Mapping, inventories, and forest monitoring constitute the support base allowing acknowledging of environments, and of conservation and evaluation methods of the natural resources, therefore permitting planning of ideal methods for the realisation of a non- passive integration between man an…
Efficacia degli strumenti pianificatori operanti in Sicilia per la tutela del paesaggio e della biodiversità: il caso studio di Lampedusa
2021
I processi in atto nelle aree protette dovrebbero concorrere alla conservazione e/o al ripristino della biodiversità di questi territori. Tra tutti i vincoli che insistono su un’area protetta, determinati da diversi strumenti legislativi (es. piani paesistici, regolamenti della riserva/parco, vincoli idrogeologici) la preminenza, ove presenti, spetta a quelli derivanti dalle applicazioni delle norme di tutela dei siti natura 2000. Come diversi studi dimostrano, molte specie rare e/o minacciate della flora vascolare di Lampedusa sono legate agli ambienti agricoli, mentre i consorzi pre-forestali ospitano diverse specie (corbezzolo, fillirea, mirto) non rare a livello regionale ma delle quali…
The Management of Invasive Non-Native Trees in the Mediterranean Protected Areas: Sicily as a Case Study
2022
Invasive non-native trees (INNTs) are increasingly recognized to have negative effects on biodiversity and ecosystem services in protected areas. The management of INNTs is one of the major challenges to preserving native species and ecosystems, to which more and more efforts and resources are bound to be destined in the coming decades. Indeed, the combined effects of climate change and increasing disturbance factors (e.g. wildfires) are likely to aid the spread of many INNTs in the Mediterranean protected areas, as well as favouring their competitive relationships with native species. However, the effective implementation of control measures is far from being fully achieved. I assessed how…
Potentiality of extensive green roofs soils in sustaining Mediterranean annual dry grassland of the EU-Habitat 6220*
2015
Nature-based solutions are defined as living solutions inspired by, continuously supported by and using nature (Final Report of the Horizon 2020 Expert Group on 'Nature-Based Solutions and Re-Naturing Cities'). In line with this statement and according to the European research and innovation policy agenda, green roofs (GRs) represent a fundamental requisite for urban sustainable development, being potential stepping stones for plants and animals, including those characterizing habitats of Community interest. In our work, we tested the suitability of green roofs in hosting Mediterranean annual dry grassland of the 92/43 ECC Habitat 6220* (pseudo-steppe with grasses and annuals of the Thero-B…
Agricoltura di qualità e rete natura 2000: “laboratori” del cambiamento
2011
Through the centuries, rural communities have managed their environment creating a rich landscape diversity. This represents an historical heritage both for the region and for humanity because the "world" itself represents the sum of widespread fragmentation processes following specific laws. The intense socio-economic changes of the last century, the rise of the "global" markets, in particular, have radically changed the landscape configuration and its natural quality across Europe. Natura 2000 network and the network of protected areas are currently the "open laboratories" to test a model of development that is compatible with the priceless treasure such as: species, habitats, landscape a…
PAESAGGIO VEGETALE, NATURALITÀ E RETE ECOLOGICA DEL COMPRENSORIO DEL PARCO DEI MONTI SICANI (SICILIA)
2010
I Monti Sicani costituiscono un comprensorio montuoso-collinare, a prevalente ossatura carbonatica di era mesozoica, localizzato tra le province di Palermo e Agrigento (Sicilia centro-occidentale). Esteso circa 2.800 km2 si spinge a settentrione fino a Rocca Busambra mentre a meridione fino al complesso di Rocca Ficuzza-Monte Telegrafo; ad occidente i confini sono segnati dalle colline trapanesi di Salaparuta mentre ad oriente dall’Alta Valle del Platani. In tale contesto s’inserisce il Parco dei Monti Sicani istituito con L.R. n. 6 del 14 maggio 2009 e che, in base alle determinazioni dell’ARTA, interesserebbe il territorio di 12 Comuni (Bivona, Burgio, Cammarata, Castronovo di Sicilia, Ch…
The integrated action framework of Rete Natura 2000 Basilicata
2012
Basilicata Natura 2000 network consists of 50 Sites of Community Importance (SCI) and 17 Special Protection Zones (SPZs), covering alltogether more than 17% of the regional area. This network, partially overlapping other forms of land protection, represents a valuable environmental, agricultural and cultural heritage, in which the safeguard of natural resources and landscapes has to be coupled with the needs of the local population; especially in relation to development and social welfare. The Natura 2000 project involved a panel of experts belonging to 15 different institutions, to form a steering committee with the following professional and scientific skills: vegetation, landscape, fauna…
Flora e vegetazione della Riserva Naturale Orientata "Laghetti di Marinello" (Sicilia nord-orientale)
2011
Flora and vegetation of Natural Reserve “Laghetti di Marinello” (North-Eastern Sicily) - Flora and vegetation of the Natural Reserve “Laghetti di Marinello” (Patti, NE Sicily) are examined. in this area extending 414 hectares, different environmental aspects enabled the emergence of various types of vegetation. The plant-communities are represented by halophilous communities (Juncetea maritimi), riverine hygrophilous communities (Phragmito-Magnocaricetea), psammophilous coenoses (Ammophiletea, Cakiletea maritimae), chasmophytic coenoses (Asplenietea trichomanis), woody and nanophanerophytic coenoses (Quercetea ilicis), and steppic prairies (Lygeo-Stipetea). The floristic analysis testifies …
