<p>The aim of this work was to evaluate the community of arbuscular mycorrhizal fungi spores in five areas cultivated with eucalipt (<em>Eucalyptus grandis </em>W. Hill ex Maiden), pinus (<em>Pinus elliottii </em>Engelm. var. <em>elliottii</em>) and native field, in arenization process, located in São Francisco de Assis-RS. The study of arbuscular mycorrhizal fungi spore community was carried out by direct and indirect identification and the diversity index determination. The analyzed areas were native field, 2 and 6 years-old eucalypt field and 2 and 12 years-old pinus field. The obtained results showed that the most frequent genera were <em>Acaulospora</em>, <em>Scutellospora</em> and <em>Glomus</em>. The highest diversity of species was found in area of native field, followed by 2 years-old<em> Eucalyptus</em> area. The Cluster analyses showed a similarity of the minimum 70 % to the species of FMAs identified through spores and 50 % to the areas being studied.</p>
