Abstract

The present study aimed to evaluate the composition and structure of the vegetation in two environments of Miombo, being the first denominated Site I (Miombo forest stretch) and Site II (abandoned area after agriculture). Fifteen plots of 20 m x 50 m were established in each Site. All woody and regenerating individuals with DBH> = 5cm were measured and identified. Sampling adequacy was evaluated based on the rarefaction curves. The floristic variation pattern among the Sites evaluated through Non-Metric Multidimensional Scaling (NMDS). 40 species distributed in 21 families were registered, while in Site II 2, 19 species belonging to 10 families were found. The floristic and phytosociological parameters evaluated were density, dominance, frequency and importance value index (IVI). In descending order, Brachystegia spiciformis and Julbernardia globiflora presented the highest IVI in the Site I. Uapaca kirkiana and Diplorhynchus condylocarpon had the highest values for this index in Site II. The dominant species in Site II are those commonly found in these environments and are able to grow in anthropic areas and show a resilience recovery capacity of Miombo woodland
