The species recorded are summarized in table 8. The use of cameras produced recordings of 5 different<strong>mammal</strong> species: Wild boar, Common genet, Red fox, Stone marten and Red squirrel. The pictures ofCommon genet caused quite an excitement among the summer camp participants because in general it isnot very easy to spot the species. The pictures and the film of the Stone martens were examined by a groupof experts in the Netherlands to make sure no Tree marten was filmed. This appears not to be the case.LocationType of cameraResults (picture)Results (film)Chestnut forest 1Infrared, 40 mega pixel2x Sus scrofa (3 juv.)1x Sus scrofa (ad.)2x Genetta genetta1x Vulpes vulpes3x Bird1x Genetta genetta2x Martes foina4x BirdChestnut forest 2Infrared, 60 mega pixel1x Sus scrofa (juv.)1x Bird1x BirdLapa dos DinheirosFlash light, 40 mega pixel2x Genetta genetta2x BirdNo films madeSenhora do <strong>De</strong>sterroFlash light, 40 mega pixel2x Martes foina1x Sciurus vulgaris2x Genetta genettaNo films madeTable 8.

6.2 OTHER RECORDINGSBesides the <strong>survey</strong> methods described above, (camera-traps to record larger <strong>mammal</strong>s, traps to catch small<strong>mammal</strong>s and mist nets and detectors for bat research), a considerable number of casual sightings, dea<strong>da</strong>nimals and observations of all kinds of tracks were recorded during the summer camp. In this chapter, asummary is given of these observations in Serra <strong>da</strong> Estrela. With these additional <strong>survey</strong> methods, 13<strong>mammal</strong> species were recorded in the Serra <strong>da</strong> Estrela: Western hedgehog, Pyrenean desman, Iberian mole,Rabbit, Red squirrel, Southern water vole, Lusitanian pine vole, Black rat, Red fox, Stone marten, Otter,Common Genet and Wild boar. The presence of 7 of these species was not established with any other <strong>survey</strong>method (Hedgehog, Pyrenean desman, Iberian mole, Rabbit, Southern water vole, Black rat and Otter).Hedgehog (Erinaceus europaeus)us)Four sightings of hedgehogs were recorded, including locations near Avoco, in the old Chestnut forest andnear the village of Loriga.Greater and Lesser white-toothed toothed shrew (Crocidura russula / suaveolens)On July 29 th , some shrew droppings were found which were attributed to a Crocidura species.Pyrenean desman (Galemys pyrenaicus)Droppings of the Pyrenean desman were found at various locations on stones in the streams northeast ofLoriga. Several attempts to catch the <strong>De</strong>sman with fish traps (which are half above the water) in variousmountain streams were unfortunately unsuccessful.Iberian mole (Talpa occidentalis)Four observations of the Iberian mole were recorded. All observations concern mole hills, mostly on grassyfields in agricultural areas.Rabbit (Oryctolagus cuniculus)During the summer camp, several sightings of rabbitwere recorded and tracks were found in severallocations (eight records). The sightings (up to threerabbits at the same time) were made in the vicinity ofLoriga and on the way up to Torre. One dead rabbitwas found.Red squirrel (Sciurus vulgaris)Twelve observations of Red squirrels were made.Half of these concern tracks (food remains). Fouranimals were actually seen and two road kills werefound. The squirrel has expanded its distribution areain Portugal and has become quite abun<strong>da</strong>nt in themixed and coniferous forests in and around Serra <strong>da</strong>Estrela.Red squirrel in the forest near Lapa dos Dinheiros.Photo: Cláudio ÁlvaroSouthern water vole (Arvicola sapidus)During a trap inspection on August 3 rd , a sighting of Southern water vole was recorded near LagoaCompri<strong>da</strong> in the higher parts of the park. Many droppings were found here as well, but attempts to capturea water vole with pit-falls were unsuccessful.Lusitanian pine vole (Microtus lusticanus)On July 29 th , a dead Lusitanian pine vole was found in a cave during a mist netting activity. Apart from theresults of the examination of owl pellets, this is the only Lusitanian pine vole reported during the summercamp.Mammal <strong>survey</strong> Serra <strong>da</strong> Estrela - Portugal 2009 33
