The Iberian hare Lepus granatensis is a common and abundant species throughout the Iberian Peninsula; however, studies documenting its ecology are scarce. Between August 1996 and September 1997, after a long drought, we studied the effects of a widespread flood on the Iberian hare ecology in ecotone pastures of Doñana National Park. Hares were captured using vertical nets through part of 1996 and 1997. Fourteen adult hares (nine females and five males) were tagged with radiocollars and located by triangulation on a daily basis at least once a week. Habitat use was estimated using a geographical information system. The average home range size was 28 ha for males and 24 ha for females. No significant differences were observed between sexes. Significant differences were observed in the use of scrub areas and in dry pastures. During the dry and wet seasons, males and females were most often located in the pastures of the ecotone, rush stands and scrub. The dense bracken (Pteridium aquilinum) and seaside bulrush (Scirpus maritimus) communities were avoided. These results are the first on the spatial ecology of this species in its native habitat.

The whole area of distribution of the Spanish ibex Capra pyrenaica Schinz, 1838 population of Sierra Nevada Natural Park was surveyed for the first time during July-August 1993 and the densities were estimated by using the line transects method. A mean density of 7.69 ± 0.50 ibexes/km2 was obtained, with sex ratio (males/ /females) of 0.80 and kids/adult females rate of 0.39. Data on size and composition of groups and on altitudinal distribution are also included. The demographic trend of ibexes in Sierra Nevada during last 30 years is reconstructed on the basis of data referred to the National Game Reserve, located within our study area.
