This issue highlights the role of grazing in restoring biodiversity with Craig Morris’ feature article on what he learned from investigating “Regenerative Grazing Management” and Susan Marais’ stories of farmers who have seen good results from implementing ultra-high-density grazing. In a case study, Craig Galloway answers the question of what the ideal stocking rate on a pasture-based farm should be. In another feature article, Ken Coetzee explains why we need to be concerned about Prosopis having already spread over 1.8 million hectares of South Africa. And if you have ever wondered how much water we can save by removing alien plants, please read the hydrological study done by a team of researchers from the ARC, Stellenbosch University and the University of Cape Town. New technologies are helping us to collect highly detailed data on the Earth’s land cover (page 39) and smart maps to protect water supplies (page 42).
