Abstract

Eragrostis plana Nees or, popularly, grass lovegrass, is an African plant introduced in Southern Brazil some years ago which infested a part of the Pampa biome, with occurrences in several Brazilian states. The present work intended the identification of grass lovegrass their occurrence and intensity of the infestation through satellite imagery of high resolution, with support of field survey in a sector of the municipality of Santana do Livramento, Rio Grande do Sul State. The grass lovegrass occurs as a mean value in about 17% of the area. Six classes of land use were considered, with amplitude related to winter-summer contrast. The method allows an evaluation of grass lovegrass distribution and it’s dynamic in the study region with potential for extension for all region.
