 Monoculture stands out as another relevant issue affecting the "campo rupestre"; eucalyptus plantations represent a serious threat due to their ability to thrive in poor soils, such as the ones found throughout this ecoregion.General misconceptions that grasslands and rocky outcrops present low levels of biodiversity, given their dry and "homogeneous" aspect, have only worsened this situation.The eucalyptus plantations not only reduce the number of native species but they also promote intense fragmentation of the "campo rupestre"; in less than 20 years the southern portion of the Espinhaço Range registered an impressive increase in the planted area of eucalyptus (30 thousand hectares), drastically intensifying habitat fragmentation.
