M.  aSapling growth of native trees in Nhecolandia sub-region, Pantanal Mato-Grossense, Corumba, MS.  c1992  ap.347  aThe Pantanal economy is based on beef cattle ranching, where the most utilized natural resource are native pastures. The "cordilheiras" (ancient levees, covered with vegetation such as "cerrado" and "cerradao" woodland, semi-deciduous forest and gallery forest) are used mainly as animal refuges in the flood season, and as source of wood for maintainance of the ranches. Recently there have been changes in the traditional production system, such as planting of cultivated pastures on "cordilheiras" areas, and the subdivision of pastures. These pratices have increased both seelctive and non-selective deforestation. This has raised serious concerns since the best management that should be used is yet unknow. Basic information on the botanical community is necessary to define a forest management plan in conservation principles. Forest regeneration involves recruitment, survival and growth of a large number of species which may differ in growth form and in the roles played in this process. Resprouting is common in tropical trees, but severe fire may substantially reduce this, altering also the seed bank, so regeneration will depend on immigration. Regeneration by seedlings may be more important than through seed banks for some tropical trees, as seeds suffer high predation and deterioriation.  The objective of this work to study sapling growth of seven species which are commonly used for fence poles in the Pantanal.  abotany  aPantanal  aBotânica  aCrescimento  aFlora  aArvore nativa  aGrowth  aMato Grosso  aNative trees  aNhecolandia1 aMATTOS, P.
