I have started taking more data now, I have 8 replicates right now three times in a day. I have started going very early in the morning and I have seen deer inside more. I have also seen eagles taking away wheat heads probably to feed the baby. but now weeds are coming up again due to heavy rain, so it is hard to track deer footprints at locations. but so far my design is working well and all my data is giving me a positive correlation with my hypotheses. I have seen some barley damage too but wheat damage is more especially in the hornless and tall variety.
Also now during weekend, there will be no human activity so I will collect data on Monday to check if there is more damage on average per day or not.
You need many replicates of human presence vs. not to say whether human presence has an influence. Also, what about your presence?
