Woody encroachment threatens savanna ecosystems around the world. In midwestern United States, remnant oak savannas persist in a woody‐encroached state due to removal of grazing and fire disturbances from landscape. Primary restoration methods, such as thinning fire, can promote dense shrub layer. Therefore, it is necessary explore other tools control woody species, targeted grazing. We conducted an experiment evaluate effectiveness cattle method its impacts on herbaceous community. used...
Despite the large body of theory concerning multiple disturbances, relatively few attempts have been made to test theoretical assumptions how and if disturbances interact. Of particular importance is whether disturbance events are linked, as this can influence probability intensity ecological change. Disturbances linked when one event increases or decreases likelihood extent another. To end, we used two long-term, multi-disturbance experiments in northern Wisconsin determine earthworm...
Temperate savannas are unique, biodiverse ecosystems that have undergone extensive habitat conversion globally. In the midwestern United States, 99% of historic oak savanna area has been lost. Most remaining patches degraded due to woody encroachment following removal both fire and large herbivore disturbances from landscape. Restoring remnants is challenging because we lack an understanding how best apply contemporary restoration tools mimic disturbance dynamics. To end, evaluated outcomes...
Summary Woody plant encroachment in grasslands is a world‐wide concern. Assertions that abiotic stress reduction facilitates are not universally supported. To devise restoration and management strategies, the ability of reduction, context co‐occurring biotic land‐use legacies, needs to be assessed predict shrub cover. We determined whether legacy‐induced Carex stricta (a potential facilitator attractor animal dispersers) an increase herbaceous invaders (potential competitors) altered woody...
