Abstract

This work present the evaluatíon of phenologic behave of the arboreal vegetation in order lo determine its possible use as biological indicator of "El Niño" events. The evaluated trees were Caesalpinia spinosa, Duranta armata, Carica candícans, and Cítharexylum f1exuosum. The resulls showed a high variation in phenologic answer. C. spínosa for example began flowering befo re shoot in 1995 and 1996; in 1997 began before, but had a short duration, and in 1998 it had presented in a late and brief period, while the foliage covering had been maintaíned constant. In the case of D. armata and C. f1exuosum the f10wering occurred after the shoot. but both cases during 1998 did not present flowering; and C. candicans presented Iloweríng before the shoot, bul wilh hígh variability in flowering size.
