de Luco, D. 2007: A large-scale survey of brown hare Lepus
europaeus and Iberian hare L. granatensis populations at the
limit of their ranges. - Wildl. Biol. 13: 244-251. The
historical ranges of the European brown hare Lepus europaeus and
the Iberian hare L. granatensis meet in Aragón in northeastern
Spain. We studied the relative abundances and the population
trends of the two species in 60 localities (13 for the brown
hare, 38 for the Iberian hare, and nine from the transition zone
where both species are present) by spotlighting in winter during
1992-2002. We carried out a total of 1,407 counts covering
41,511 km. Both the Iberian (132.2 ± 33.2 hares/100 km; range:
52-192) and the brown hare (106.7 ±
