Regeneração natural da vegetação lenhosa em um cerrado sensu stricto degradado na Fazenda Experimental do Glória, Uberlândia - MG

Abstract

The sensu stricto phytophysionomy, found in Cerrado biome, has been degraded by several anthropic activities. This study had as objective to identify ecologic patterns and measure the diversity of woody regeneration in a disturbed fragment in Glória’s Experimental Farm (FEG). This farm is located in Uberlândia’s east urban area. The sampling was divided into two size classes: 4m² and 100m², respectively denominated class I and class II. The parameters of frequency, density, Shannon diversity (H’) and Total Natural Regeneration Index (RNT) were calculated for each community’s specie. There were 618 individuals distributed among 45 woody species, 41 genera and 23 botanic families. The families Mapighiaceae, Myrtaceae and Sapindaceae presented the highest community’s number of individuals. The species Heteropterys byrsonimifolia, Matayba guianensis, Styrax ferrugineus and Eugenia involucrata totaled 42% of density in class I. These species, together with Leptolobium dasycarpum and Bauhinia rufa also presented the highest densities in class II. An important aspect is that most of the woody species were observed in both size classes, demonstrating good regeneration potential, even for a degraded area and in recovery stage of their species and individuals stock.
