TITLE:

Natural regeneration of hedgerows in Campo das Vertentes, MG.

KEY WORDS:

hedgerows, vegetation community structure, phytosociology, floristic diversity, floristic composition, ecological group

BIG AREA: Ciências Biológicas
AREA: Ecologia
SUMMARY:

The hedgerows are ancient excavations made in the 17th and 18th centuries by enslaved
individuals to separate land plots, and due to the lack of management in these environments after
their creation, it allowed the vegetation to colonize through propagules from adjacent areas. Due
to their concave structure, they possess a microclimate, structure, and floristic composition
similar to forest interiors and play an important ecological role in regional conservation. Despite
their potential, there had been no studies on the natural regeneration of these environments and
their ability to sustain themselves, so this study aimed to examine the structure and diversity of
two regenerating strata of shrub and tree species in four ecological corridors of valo in the
Campo das Vertentes region. Seedlings ≥ 50 cm and ≤ 100 cm in height (small stratum) were
analyzed in 4 m² plots, and seedlings > 100 cm in height and ≤ 5 cm in DBH - Diameter at Breast
Height (large stratum) were analyzed in 40 m² plots. The DBH was measured, heights were
recorded, and it was indicated in which section of the valo they were located (wall or bottom),
botanical identification was conducted for all individuals that fit these parameters. Structural
analysis was carried out using phytosociological parameters and floristic diversity of the species
in each corridor for both the large and small strata. Additionally, the same parameters were
analyzed for the species based on the section of the valo they occupied (wall or bottom). They
were also analyzed based on their ecological group and their ability to regenerate in the presence
or absence of light (shade tolerance). The floristic composition of the regenerating stratum was
compared to the adult floristic composition previously evaluated by Miguel (2019) using
dissimilarity tests.
