Prados e Pastagens

Abstract

"As pastagens constituem actualmente o habitat predominante na paisagem dos Açores. No entanto, há cerca de 560 anos, quando os primeiros colonos portugueses chegaram e ocuparam estas ilhas, a maior parte destas estava coberta por florestas densas do tipo semi-tropical, estando a presença de zonas com vegetação herbácea nativa (prados) reduzida a zonas costeiras ou bordando algumas zonas de floresta de altitude em zonas húmidas (como as turfeiras) acima dos 500 metros. Durante o processo de ocupação das ilhas, o desbaste das florestas nativas e destruição de muitas zonas húmidas permitiu a expansão de campos agrícolas a baixa altitude e pastagens a média e alta altitude. Durante os primeiros séculos de ocupação, os prados naturais e as pastagens sem i-naturais constituíram o suporte de uma produção animal sustentável, que se mantém actualmente em algumas partes do arquipélago. Essas pastagens estão implantadas em solos ácidos e encharcados com um pico de produção de erva restrito aos períodos de Primavera e Verão. A biodiversidade em muitas dessas pastagens (como no Corvo, Flores, Pico, São Jorge, Terceira e São Miguel) é elevada quer em plantas quer em invertebrados nativos, podendo-se considerar a utilização humana como sustentável em termos ecológicos.
