6. Restoration of abandoned subtropical highland grasslands in Brazil: mowing produces fast effects, but hay transfer does not
ABSTRACT Subtropical Campos Sulinos grasslands, in South Brazil, are among the most biodiverse grasslands of the world. As climatic conditions lead to high productivity, disturbance are critical to maintain their diversity. Long-term exclusion, on the other hand, leads to plant species losses and changes in composition. No studies on the restoration of these
