Restoring Ecological Functions Using Agroforestry Systems in Riparian Forests

Abstract

Agroforestry systems and restoration models were compared with native forests by examining the restoration of ecological processes that generate stability, resilience and reliability. The stability assessment was obtained using indicators of diversity, structure and functionality. Indicators of soil protection and nutrient cycling were also used to estimate the resilience. The reliability was assessed by management and protection indicators, anthropic impact and canopy (percentage of light). Agroforestry systems did not promote the restoration of ecological functions due mainly to structural factors than management. The production of biomass and carbon storage were higher in the agroforestry system considering the association of trees with short cycle crops (3.2 t ha -1 yr -1 ; 39.81 t C ha -1 ) than trees with green manure system (2.4 ha -1 yr -1 ; 34.09 t C ha -1 ). After 36 months, the restoration methods and agroforestry systems did not provide resilience and stability for the riparian forests protection.

“…Para cada um deles existem denominações distintas que variam de acordo com os principais produtos gerados em cada sistema (MICOOLIS et al, 2016). Os sistemas mais diversificados e similares aos ecossistemas florestais naturais são conhecidos por agroflorestas sucessionais ou biodiversas, caracterizadas por alta diversidade de espécies e cujo manejo baseia-se na sucessão natural das espécies (GOTSCH, 1992;PENEIREIRO, 1999;HOFFMANN, 2013;VIÉGAS et al, 2019).…”
