Disturbances change the fundamental properties of grasslands on different spatio‐temporal scales. Uruguay is part of the Río de la Plata grasslands, and 60% is occupied by native grasslands dominated by perennial species. In plant communities dominated by tall tussock grasses, patchy and asynchronous field burns are a traditional practice among ranchers. We asked: how do the structural characteristics of vegetation vary in patches with different time since the last fire?

自从南美草原火灾增加以来，异质性随着时间而减少

扰动改变了草地在不同时空尺度上的基本特性。乌拉圭是Ríode la Plata草原的一部分，其中60％被以多年生植物为主的原生草原所占据。在以草丛为主的植物群落中，斑驳和异步田间烧伤是牧场主的传统习俗。我们问：自上次火灾以来，不同时间的斑块中植被的结构特征如何变化？
