Habitat selection by European badgers in Mediterranean semi-arid ecosystems

Zusammenfassung: | We studied the habitat selection patterns of badgers
Meles meles (Linnaeus, 1758) in Mediterranean semi-arid ecosystems. Fifty-seven plots were sampled in two semi-arid regions of Spain. In each plot, badger latrines were located along 2.6 km transects. The number of badger latrines per km was used as a surrogate of badger abundance and as an index of habitat selection by badgers. For each plot, a series of environmental variables were measured at two spatial scales. These variables were related to land use and vegetation formation parameters that are considered potentially important for habitat requirements (i.e., food and shelter). The habitat selection model was carried out using generalised linear models (GLM) and an information-theoretic approach. Results indicated that badgers prefer fruit orchards, and shrub and rock-covered areas, which provide additional trophic and shelter resources, and avoid intensively cultivated fields and human settlements. We conclude that badger conservation in semi-arid environments of the Iberian Peninsula requires the existence of fruit orchards and the limitation of human development. Policies restraining agriculture intensification would encourage traditional or new non-intensive agricultural practices and increase shrub-patch availability, which would benefit this species.
► We model the habitat selection patterns of badgers in Mediterranean semi-arid ecosystems. ► Badgers select fruit orchards, shrub and rock-covered areas, and avoid intensively cultivated fields and human settlements. ► Policies that encourage traditional agricultural practices would benefit badgers. ► Badgers would benefit policies that restrict human development. |
