Native flora conservation in agroforestry system

Abstract

One of the major causes of environmental degradation is the dominant predatory model of
agriculture. Thus, models based on ecology and the integration of people into the landscape
are needed to provide biodiversity conservation combined with the production of food and
other goods. Agroforestry systems represent a type of agroecosystem with the potential to
meet the demands of these new models. In this context, the objective of this study was to
analyze the contribution of an agroforestry system to the conservation of native tree flora, with
natural regeneration as an indicator. Regenerating individuals were sampled in an agroforestry
system and an unmanaged secondary forest for analyzes of richness, equability, diversity and
similarity. The agroforestry system presented greater richness and higher diversity indexes,
confirming its function in the conservation of native flora in a landscape with a fragment of
conserved vegetation.
