The integrated “Spelaion Logos” projects aim at enhancing the Karst cave environment of naturalistically-relevant protected areas - that are part of Natura 2000 - in the Eastern Alpine Arc. They are the result of the cooperation among the various partners, and envisage environmental restoration and improvement activities (creation of thematic routes and infrastructural interventions to improve site fruition) as well as educational/cultural initiatives (educational exhibitions, conferences, promotional and publicity literature). As regards Valcellina, the project aims at the creation of a naturalistic-educational trail with a low impact on the environment, both epygean and hypogean, that comprises - in its open-air portion - the Natural Reserve of Forra del Cellina, and - in its underground portion - the Grotta Vecchia Diga (Old Dam Cave) of Barcis. Also envisaged is the establishment of an multifunctional Educational-naturalistic Centre, that will promote knowledge dissemination and a correct fruition of the fossil caves and the exceptional natural resources present in the Reserve. Project activities also include the setting up of an Image Laboratory/Archives for the study and the dissemination of information on the territory and the creation of a multimedia network for the cultural, technical and scientific exchange between project partners; the organisation of cultural initiatives and events; promotional literature; and symbolic naturalistic/educational itinerary will be set up, targeting school and excursionist tourism, leading from the Pordenone Prealps area to the Julian Prealps and the Slovenian National Park of Triglav. The project is coordinated by a Technical Committee consisting of both Italian and Slovenian partners who, by sharing the competences acquired by individuals, aims at attaching to the actions proposed a high technical and scientific value.
