Plantas exóticas e invasoras na Ilha do Pico (Açores).

Authors: Almeida, Maria T.;

Plantas exóticas e invasoras na Ilha do Pico (Açores).

Abstract

As ilhas são lugares ideais para a instalasão e desenvolvimento de plantas invasoras, quer sejam trazidas por meios naturais ou pelo Homem. As plantas invasoras são bastante agressivas, e como ao chegarem a uma ilha raramente encontram os seus inimigos naturais, elas espalham-se muito rapidamente e desalojam as plantas nativas. Por um lado com a sua presença elas parecem aumentar a Biodiversidade total da Ilha, no entanto com a sua agressividade elas são responsáveis pela diminuição da Biodiversidade natural primária. As plantas exóticas, normalmente trazidas pelo Homem, com fins económicos e/ou ornamentais, podem também tornar-se plantas invasoras. É, de qualquer maneira, elas constituem uma alteração da paisagem natural. Dado que as fronteiras das ilhas são o mar e o ar é relativamente fácil, e absolutamente indispensável, que se controle a entrada de plantas exóticas, isto é, não nativas. Por outro lado deve-se fazer o controle e irradicação de todas aquelas plantas exóticas e invasoras que existam, ou sejam detectadas, nas ilhas. Segue-se uma lista de Plantas Exóticas e Invasoras detectadas na Ilha do Pico durante a Expedição Científica PICO/91, organizada pelo Departamento de Biologia da Universidade dos Açores.
