Heterogeneity decreases as time since fire increases in a South American grassland

Prepared by Luis López-Mársico, Felipe Lezama & Alice Altesor

In a sub‐humid Uruguayan grassland community, dominated by a tall tussock grass (Saccharum angustifolium), a large amount of standing dead biomass accumulates. Patchy and asynchronous field burns are a traditional practice among ranchers to removes above‐ground biomass of the dominant species and to promote tender forage for the livestock.
