Agrobiodiversidade de quintais agroflorestais em um assentamento rural no Baixo Amazonas

Abstract

The diversity of plant species that make up agroecosystems these are fundamental factors for ecological processes, as they comprise dynamic and multi-layered environments. Agroforestry yards represent an important strategy for the conservation of natural resources and a source of self-consumption for families. Given this context, the present study aimed to analyze the floristic composition of 21 agroforestry yards established in the community of Moacá, Settlement PAE LagoGrande. The methodology applied was Snawball, which analyzed 7 old QAF's (over 40) and 7 new QAF's (0 to 25 years), and 7 intermediate QAF's (25 to 40 years). In addition to this procedure, socioeconomic questionnaires and a 100% inventory of species were performed to assess diameter, breast height (DBH), total height, number of species per yard, popular name, uses (food, shade, spice, medicinal, ornamental, and others) and life forms of the species (shrub, shrub, arboreal, herbaceous, creeper and palm). Therefore, 1342 individuals, 22 species and 56 botanical families with the most different habits and uses were registered. Among the families, Lamiaceae, with the largest number of species, and Musaceae, with the largest number of individuals, gained prominence. The backyard classification determined that species abundance, density and richness were higher in the category of old backyards, over 40 years old. On the other hand, the highest diversity was observed in the intermediate yards, whose average reached 2,35.
