"Brazilian roadsides along paved highways are the scenario of many environmental problems. (a) Area along MG-10 left alone for many years and later ill-restored with noxious weeds by the Department of Roads of the state of Minas Gerais (DER-MG). (b) Spread of ruderal and invasive species into pristine vegetation from highway MG-10. (c) ""Restoration"" of highway MG-735 roadside in Minas Gerais (DER-MG) with exotic African grasses and other species. (d) Use of roadside along highway GO-118 (Brasilia-Alto Paraíso) to expand the plantations of soybean and bean. (e) Plantation of corn to the very edge of the RS-472 in Rio Grande do Sul state. (f) Plantation of soybean and plantation/invasion of pine trees along BR 290 in the Pampa, Rio Grande do Sul state."
