Resumo
Mauritia flexuosa (buriti palm) is considered a key species in the swampy environment and little
is known about their population structure to support its management and conservation strategies. This work
investigated six populations of this species, from swampy areas with different degrees of human disturbance
in the municipality of Bela Vista de Goiás, Silvânia and São Miguel do Passa Quatro, GO, in the nuclear region
of the Brazilian Cerrado, a savannah-like vegetation. Plant height data were collected from 584 individuals,
from seedlings to adults, with 100 sampled individuals per population, excluding one, in which 84 individuals
were sampled. Most of the studied populations showed distribution of individuals in plant height classes according
to expected inverted-J shaped curve, a self-regenerating population characteristic. The highest proportion of
dead individuals occurred in the first height class and the highest life expectancy occurred in the height class
with interval from 3.5 m to 7.0 m.
