Grazers and fire management: conservation from a ‘systems’ perspective

How do grazing herbivores like hippos affect the influence of fire? Following a recently published article, Izak Smit demonstrates the need for interdependence between herbivore and fire management. Grazing animals and fire are in direct competition – both of them consume grass. Previous continental-scale studies suggest that grazing animals have the competitive advantage in drier and more nutritious landscapes, whilst fires dominate in wetter and … Continue reading Grazers and fire management: conservation from a ‘systems’ perspective

Where should we build wildlife crossings?

With wildlife crossing locations difficult to pinpoint, how do we know where to build crossing structures? Associate Editor, Manuela Gonzalez-Suarez explains how Bastille-Rousseau et al.’s new method and recent article, Optimizing the positioning of wildlife crossing structures using GPS telemetry help answer this question. There are over 40 million km of roads in the world (100 times the distance from the moon to Earth), with many millions … Continue reading Where should we build wildlife crossings?
