摘要: Abstract Starting from a data‐set of 175 point counts (5 min duration) repeated twice year 1992 to 2002 in the Foreste Casentinesi National Park (Apennines, central Italy), trends species and some selected ecological phenological guilds were analysed. Among 61 testable species, significant increase (linear or quadratic regressions) involved 15 whereas 8 decreased. No trend was found for remaining 38 species. The bark feeders guild, as well tree‐cavity nesters ground showed an increase, foliage no changes. Short‐distance migrants residents long‐distance change. overall picture obtained these data fits habitat changes occurring study area: i) ageing woods (with remarkable proportion mature stands period); ii) afforestation pastures farmland, long‐term process that star...
