Resumen
Earthmound field is a savanna types characterized by the occurrence of mounds in the
presence of flora shrub and tree free flood spread over a grassy field matrix seasonally
waterlogged or flooded. The present study aimed to characterize the earthmound fields of
flood plains Guapore in terms of physiognomy and floristic and compare them to
earthmounds fields being studied and the literature, situated in the flood plains of the
Pantanal, Araguaia, Bananal and plateaus of Brazil Central.. The work was carried out at the
Parque Estadual Corumbiara (PEC), Rondônia. We studied four earthmounds fields of one
hectare each. All earthmounds were counted and measured (length, width and height). All
species on mounds with stem diameter at breast height ≥ 5 cm were sampled. The Herbaceous
grassland matrix were sampled at 250 points on an axis by earthmound. To check relations
with nine other areas of Central Brazil was the method used by TWINSPAN classification.
We recorded a total of 620 mounds, with an average density of 155 mounds / ha, average area
of 15 m2 and an average height of 0.55 m, with smaller area and higher density and height
than earthmounds on the plateau of Central Brazil. We recorded 29 botanical families, 50
genera and 60 species, 41 in the woody layer and 19 in the herbaceous layer. The families
with greater wealth were Poaceae and Fabaceae. Were recognized three groups of
earthmounds fields mounds by TWINSPAN groups from the core region of the Cerrado, flood
plains of central Brazil and floodplain of Guapore in area of cerrado enclave within the
Amazon biome. The separation of these groups is associated with differences in the floristic
composition of each locality. This was the first survey work flora and physical
characterization of earthmounds fields in the floodplain of the Guapore. This study is
required to facilitate the development of specific regulations, adjusted to the peculiarities
presented by these environments, contributing to the conservation of these areas.
