INTRODUCTION
 What is holistic grazing management?
 How does it compare to traditional grazing?
 Where has it been practiced?
 Why are we interested in studying it?
METHODS
 Health
 Milk yield measurements
 Growth rates
 Vegetation and wildlife
 Vegetation transects
 Camera traps
 How much the plots are
being used and by what
animals
 GPS data – our livestock
 Camera traps – wildlife
 Production cages
METHODS
GPS DATA – TRACKING LIVESTOCK
GPS DATA

PERCENTAGE TIME ANIMALS SPEND IN
THE BUNCHED GRAZING AREA

FUTURE STUDY
 What we expect to see from the animal health measures
 What we expect from the production cages
 What we expect to see from the camera trap pictures

Impact of seasonal changes
Investigate mechanisms through which this ef fect could occur
