Patch selection by cattle can be quantified using satellite imagery and GPS in extensive,semi-arid savannas

摘要：

Introduction Patch selection by grazing animals is difficult to quantify,particularly in large,extensive paddocks like those in northern Australia.However,advances in high resolution satellite imagery now allow identification of patch types over an entire paddock which combined with GPS collars to capture positional data,can give an accurate and comprehensive picture of landscape use by cattle.
