A population of the lacertid lizard Podarcis hispanica was studied in the Sistema Central Mountains in Salamanca Province, Spain. Lizards confined their activities to stable home ranges, but size range varied enormously between individuals. Home ranges generally contained 1) a high proportion of rocks > 100 cm in height and 2) a significantly higher abundance of crevices than expected. The overall abundance of lizards increased with decreasing amounts of shrubs and herbaceous plants cover and densities were highest in bare and rocky areas. Adult females selected particular habitat types according to the season, whereas habitat selection of males and juveniles did not differ between spring and summer. Non-resident adult lizards and juveniles occupied habitats of marginal quality in relation to crevice abundance.
