The severe drought in 1994 damaged the woody flora of central and southern
Spain (80% of the 190 studied sites presented drought-damaged species). In
1996, after a wet year, 67% of the sites were still affected. Different deg
rees of damage and recovery were found among different functional types (tr
ees or shrubs), and genera of different evolutionary history (Mediterranean
or pre Mediterranean). The Mediterranean genera, mostly shrubs evolved und
er Mediterranean climate conditions, i,e., later than 3.2 M years ago in th
e Pliocene, were more damaged by the drought than the earlier evolved pre-M
editerranean genera, mostly trees. However, the Mediterranean genera were m
ore resilient and recovered much better after the following wet year.
