This study was done on a Seasonal Semideciduous Montane Forest located at Pico do Jabre state Park (06°
02’12’’ S and 34° 45’12’’ W) between Maturéia and Mãe D’água (PB) municipalities, placed 360 km from
the sea and includes the highest regional elevation (1197 m). It aims to investigate tree spatial distribution
of populations and its association to local environmental factors to test the hypothesis that the spatial
distribution of species along topographical gradient reflects different communities. To reach this target
UPGMA, TWINSPAN and the indicator species analysis were complementarily applied, with significance
of VI by Monte Carlo test. The results showed two floristic communities: PP including preserved plots and
PAR colonizing disturbed and rocky plots. To highlight PP and PAR floristic differences a separated phytosociological
analysis was run. Results showed distinct richness, diversity, density, low similarity and high
beta diversity among communities.
Byrsonima nitidifolia
, and
Maytenus distichophylla
were found as PP
indicator species and
Eugenia ligustrina
,
Erythroxylum mucronatum
and
Myrciaria floribunda
as PP preferential.
There were no PAR indicator species.
Miracrodruon urundeuva
and
Sapium glandulosum
stood
out as PAR preferential species. The indicator species analysis showed five as preserved environment and
three for disturbed/rocky environment indicators, as well as, floristic and structural differences along communities,
formed according to human activities and rockyness.
