7. The Open Plan for Planned Grazing in the Growing Season Three Guiding Principles 1.Do not stay too long in fast growth or overgrazing of perennial grasses will occur 2.Do not return too soon in slow growth or plants will not be fully recovered 3.Minimising the number of mobs will help achieve adequate recovery periods Planning stock moves based on recovery time of perennial grasses Plan for recovery times of the slowest growing species It pays to be pessimistic about growth rates Speeding up stock moves in fast growth Slowing down as growth slows down Monitor growth rates ahead and behind Planning to be at the yards at shearing time, calf marking etc Figuring out the weak link in the solar chain of production

8. Check List for Planned Grazing in the Dormant Season Do a plan for the dormant season when growth stops How many days to the ‘average’ opening rains Plan for a further time interval in case the opening rains are late Calculate how many days grazing there are at the start of this plan Will current numbers run out of feed before the number of days feed you have on farm The earlier you reduce numbers the longer existing feed will last Remember your landscape goals and do not give up on them lightly One selection or two implications for animal performance How many mobs, less is better in hard conditions What if it rains Monitoring paddocks ahead of you and looking behind the mob, gives a lot of information Reassessing grazing days remaining as the plan progresses

23. Tree Cover has increased from 3% to 15% Nine years of low rainfall, but no loss of soil cover No feeding of livestock at all Native grasses now increasing rapidly Bird count now over 120 and increasing No inputs since 1999 No increase in debt level Better at matching stocking rate to carrying capacity
