Seguiments i estudis de la comunitat de mamífers a l’Estany d’Ivars i Vila-Sana

Recently has been published a paper titled “Seguiments i estudis de la comunitat de mamífers a l’Estany d’Ivars i Vila-Sana”, made by David Guixé and Fermí Sort. In this study  are showed the results of  long term monitoring of micromammals, bats and carnivorous from Estany d’Ivars i Vila-Sana’s area.
ABSTRACT: Many species of mammals are living inIvars and Vila-Sana area, and some of them are bioindicatorsand endangered. Therefore, we have to make the best management actions for their conservation. This area had been dried completely in 1951 and recovery project was started in 2002. Since 2005 the Institute for the Study, Management and Ecosystem Recovery Lleida (EGRELL) and the Forest Science Centre of Catalonia (CTFC) carried out several projects to study the status and abundance of mammals. Monitoring small mammals, bats and carnivorous is very important as a long term project. Trapping sessions show that the most abundant small mammal species is the wood mouse (Apodemus sylvaticus) and White-toothed Shrew (Crocidura russula). Instead, Western Mediterranean Mouse (Mus spretus) nowadays appears to be less abundant due to a new wetland landscape. The water vole (Arvicola sapidus) seems to be increasing its population. About bats, ten different species have been found in the area. The most common species is a Pygmy Pipistrelle (Pipistrellus pygmaeus), a very abundant species in wetlands. The bat boxes show a tendency to increase bat occupancy, from two boxes occupied in October 2006 (3.13%) to a 35% of occupancy in 2013. An endangered species, the Long-fingered Bat (Myotis capaccinii) had been monitoring using radio tracking. It usually follows large irrigation channels, natural pools and the Ivars and Vila-Sana pond for hunting. The natural caves where they breed are situated quite far, about 30 km in a straight line.
