Resumo: | The natural grasslands of Rio Grande do Sul (RS) have been deteriorated due to widespread overgrazing, use of fire, soil tillage, erosion and by the invasion of the south african grass Eragrostis plana (capim-annoni-2), accidentally introduced in the 1950’s. Seed multiplication and use as a forage crop favored its dispersion establishment in roadsides and in the natural grassland vegetation. The invaded area in RS is estimated to be one million hectares. Integrated control, regulations of animal transport, weeding of sale yard areas, and the elimination of weed nursery will help to reduce the spreading of this species. Preventive grassland management practices might avoid invasion of new fields. The evaluation of the effects of management systems over the vegetation dynamics and the animals performance may reveal new tools capable to decrease or retain the abun- dance of this invasive species and improve biodiversity and productivity of the natural grassland. |

As pastagens naturais do Rio Grande do Sul (RS) vêm sendo degradadas por pastejo excessivo, queimadas, práticas de cultivo, erosão e pela invasão da gramínea sul-africana Eragrostis plana (capim-annoni-2), introduzida acidentalmente na década de 1950. A multiplicação de sementes e utilização como forrageira favoreceu a sua dispersão e o estabelecimento nas margens de estradas e na vegetação campestre. A área de campo infestada no RS é estimada em um milhão de hectares. Controle integrado, regulamentação do transporte de animais, desinfestação de locais de remates e a eliminação de focos dispersores auxiliarão na redução da expansão da espécie. Práticas preventivas de manejo do campo nativo poderão evitar a infestação de novas áreas. A avaliação dos efeitos de sistemas de manejo sobre a dinâmica da vegetação e da performance dos animais poderão revelar práticas de manejo capazes de reduzir ou deter a área ocupada por esta invasora, aumentar a biodiversidade e a produtividade do campo natural.
