Después de décadas de ausencia del lobo (Canis lupus) en los Pirineos, desde finales de los años noventa se han detectado algunos ejemplares solitarios en el sector oriental de la Cordillera. El establecimiento definitivo del lobo dependerá de varios factores, entre los que cabe destacar la disponibilidad de hábitat adecuado, las medidas de conservación de la especie y la conectividad ecológica del paisaje. El presente estudio analiza la disponibilidad de hábitat para el lobo en Cataluña y la vertiente francesa de los Pirineos orientales mediante la elaboración de un mapa de coste de fricción o matriz de permeabilidad para la especie en cuestión, basado en siete pará- metros de tipo territorial y ambiental. Posteriormente, se han seleccionado los espacios más óptimos para el lobo y se han delimitado las zonas geográficas más susceptibles para albergar el cánido en un futuro próximo. Los resultados del análisis confirman que un tercio del área estudiada constituye un hábitat óptimo para el lobo y alrededor del 90% de estos espacios cuentan con unas dimensiones suficientes para albergar poblaciones estables de lobos
After decades of absence of the wolf (Canis lupus) in the Pyrenees, since the end of the decade of the nineties some solitary specimens were detected in the eastern half of the mountains. Wolf establishment will depend on several factors, among which it is worth mentioning specie conservation measures, habitat availability and landscape’s ecological connectivity. The present study analyzes the availability of suitable habitat for wolf in Catalonia and the French side of oriental Pyrenees, by means of a map of resistance surfaces for the predator based on seven territorial and environmental parameters. Afterwards, the most suitable zones have been selected and have been delimited those geographic areas which could be home for wolves in a near future. The results of the analysis confirm that one-third of the studied area constitutes an optimal habitat for wolf and around 90% of these spaces are provided with enough dimensions to hold stable wolves’ populations
