%X A question that has been discussed is the role that reforestations with exotic species in native fauna and several studies have shown that removal of propagules is lower in these environments. This study compared the removal rate of propagules (araucaria seeds, peanuts, corn) from areas of native forest (FN), reforestations of Pinus taeda L. (RP), Eucalyptus saligna Sm. (RE) and Araucaria angustifolia (Bertol) Kuntze (RA). In FN all propagules were removed. There was no difference in the removal of araucaria seeds between FN and RA, and removal rate in both areas differ from the removal rate in the RP and RE. In RP there was high removal of peanuts, while the RE showed the lowest value of removal of the three propagules. The low removal rates in reforestation of pine and eucalyptus reflect the decreased exploitation of these habitats for wildlife, which may be related to a poorly structured understory. Uma quest o que tem sido discutida ¨¦ o papel das monoculturas florestais ex¨®ticas na manuten  o da fauna nativa e v¨¢rios estudos t¨ºm mostrado que a remo  o de prop¨¢gulos ¨¦ menor nesses ambientes. O presente trabalho comparou a taxa de remo  o de prop¨¢gulos (pinh o, amendoim, milho) entre ¨¢reas de Floresta Nativa (FN), Reflorestamentos de Pinus taeda L. (RP), de Eucalyptus saligna Sm. (RE) e Araucaria angustifolia (Bertol) Kuntze (RA). Na FN, todos os prop¨¢gulos foram removidos e n o houve diferen a significativa na remo  o de pinh o entre a FN e o RA. A remo  o de prop¨¢gulos nessas ¨¢reas diferiu da remo  o no RP e RE. No RP, houve alta remo  o de amendoim, enquanto que o RE apresentou os menores valores de remo  o dos tr¨ºs prop¨¢gulos. As baixas taxas de remo  o nos reflorestamentos de pinus e eucalipto refletem a menor explora  o desses habitas pela fauna, o que pode estar relacionado com um subosque pouco estruturado.
