L’objectiu principal d’aquest projecte és establir les propostes de gestió necessàries per tal de poder preservar els espais oberts a la zona de Sant Sadurní d’Osormort (Guilleries), i poder ho fer extensible a altres zones de Catalunya i d’Europa. Per dur a terme l’ estudi utilitzen com indicador els lepidòpters ropalòcers de zones obertes . Aquest projecte proposa millores en la gestió del territori d’estudi, per tal d’aconseguir una millora en l’ecosistema i una millor connectivitat biològica

El massís de les Gavarres és un espai que forma part del Pla d’Espais Naturals d’Interès Natural de Catalunya i es caracteritza per ser un espai molt ric en patrimoni cultural, sobretot etnològic. És per això que des de l’entitat del Consorci de les Gavarres sorgeix la proposta d’elaborar un conjunt de senders ecoturístics sobra la Zona d’Interès Etnològic de la Gavarres. L’objectiu principal és impulsar la posta en valor i crear instruments de gestió dels principals elements del patrimoni cultural que es troben presents arreu del massís de les Gavarres, a partir del disseny d’un conjunt de senders ecoturístics que, de manera respectuosa amb el medi ambient, serveixin d’instruments de dinamització i de gestió per a la conservació de l’espai i els seu elements patrimonials.

The behaviour of 21 natural springs in a granític massif is studied in this survey. Geomorphological features of the zone are described as well as water circulation and rising 25 parametres of each of them are analysed ans conclusions are withdrawn regarding geological conditions of rising, course, chemism and potability

A series of circumstances which converge in a little valley in the province of Girona, result in a peculiar type of morphogenetic evolution and a quite singular mechanical instability of its buttons. Very recent tectonic movements as well as dissolution phenomena of its subsoil due to pressurized underground water have played an important role in the morphogenesis. Such conditions have resulted in a fast morphological evolution which a progressive lowering of the valley floor as well as peculiar morphological features which favour the existence of numerous pits caused by sudden collapses distributed in altitude and time

The Guilleries are a small and mountainous area located in the north-westem part of the Catalonian Coastal Ranges where metamorphic and igneous Paleozoic rocks are exposed. After the main hercynian folding this area was affected by a brittle deformation that is mainly manifested by the intrusion of a very large number of dykes of granodiorite and the development of a complex joint system. Trends of dykes indicate that their intrusion was related to a SE-NW extension, whose estimated value is 40% on an average. This extension seems to stand, although without any associated igneous event, with the development of NE-SW directed joints which make the main set. Five families more were developed later, one gently-dipping and fou upright; the latter trending roughly SE-NW, ENE-WSW, ESE-WNW and N-S. AU the joint sets appear in the metasedimentary Paleozoic rocks and in the hercynian intrusive bodies. Concerning the ages, joints that belong to the NE-SW and SE-NW directed sets and also those slightly dipping have been attributed to the late-hercynian times and all the other are considered to be later

The Paleozoic materials of Massís de Begur are described from a stratigraphical point of view. We distinguish two units: the lower one, present phillites with carbonate layers of cambro-ordovician age. The upper one is composed by volcanic rocks, carbonate schists and black slates, bring from caradocian and ashgillian age
