Modelling habitat use by Iberian hare Lepus granatensis and European wild rabbit Oryctolagus cuniculus in a mountainous area in northwestern Spain

摘要

We developed broad-scale habitat use models for the distribution of the Iberian hare Lepus granatensis Rosenhaeur, 1856 and the relative abundance of the European wild rabbit Oryctolagus cuniculus (Linnaeus, 1758) in a moun-tainous area in north-western Spain, the Baixa Limia Site of Community Importance (SCI). For the Iberian hare, the most parsimonious model included average altitude, average slope, scrub-pasture area and length of border between scrublands and forests. Four variables were consequential, 2 of them with a positive sign for the presence of the hare (average altitude and scrubland area) and 2 with a negative one (average slope and length of border between scrubland and forest). For the European wild rabbit the most parsimonious General Linear model obtained included average altitude and scrub-forest edge. Only 2 predictors were consequential, both with a negative sign on the relative abundance of wild rabbits: the average altitude and length of border between scrubland and forest. The models obtained indicated the need of man-agement actions to favour open habitats with suitable vegetation structure, avoiding extensive reforestation. A revision of the current hunting plans in the protected area of Baixa Limia is required.
