Adjusting stocking rate to changing forage conditions is a critical part of pro-active range management. In general stocking rate approaches tend to assume more optimal landscape use patterns than will actually occur. Today we can monitor spatio-temporal landscape use on a 24/7 basis using animals instrumented with global navigation satellite system (GNSS) devices. Sequential 1 sec fixes taken from two cows in two different herds in 2009 and 2011 within a 433-ha arid rangeland paddock provides an example of how GNSS data categorized into stationary, foraging and walking behaviors can be used to calculate a more accurate SR.
