ABSTRACT An analysis of the importance of Carnivores for the forests and viceversa is realised.
Their capacity for spreading seeds, their function as controllers of lhe species, which are diminishing
the regenerational capacity of the forest and their funclion as predators, are dealt
with. The importance of forests and riverbank thickets are emphasised, as are subalpine forests,
pyrenean and Cantabrian highlands and the Mediterranean forest. Furthermore, the
role of forest management with regard to the most common forest species (Pine Marten
and Genet), which possess a bioindicatory character of the maturity of the forest are studied.
The feeding, reproductory and habitat selection strategies of the Stone Marten, the
Pine Marten, the Badger, the Genet and the Wild Cat are presented and the competence
relationship between Pine Marten-Stone Marten and between Stone Marten-Genet is
discussed.

    ABSTRACT: Distribution and abundance of small carnivores in the Montnegre-Corredor Natural Park by photographic trapping We studied the distribution of wild and domestic carnivores in the Montnegre-Corredor Natural Park (coastal range, Barcelona) by photographic trapping. Six equipments (with an automatic 35 mm compact camera, a 12 volt battery, and infrared sensor) were arranged in 111 different 1 km 2 UTM units between february and june of 2002. The area sampled was about 74% of the natural park. During this period 1058 pictures were obtained, carnivores being the subject in more than a half (576 shots, 54,4%). We obtained 460 shots of the common genet Genetta genetta, 39 shots of the stone marten (Martes foina), and six shots of the red fox (Vulpes vulpes). Two domestic species were found, the dog (Canis familiaris, 44 shots) and the cat (Felis catus, 27 shots). The genet showed the highest frequency of occurrence (31,81%) and a significant altitudinal pattern of distribution, being more frequent in the middle altitudes (300- 600 m.a.s.l.) than in lowlands or in mountain tops. The stone marten was the second species in frequence (18,18%), but did not show significant patterns with altitude. Dogs did not show association with altitude, but were more frequent in areas with moderate roughness. We discuss the distribution of wild carnivores
