Been thru all this in past threads and not going to write it all over again. In very simple terms for you each trap position will cater for 2 ha. A 100 position grid line will cover 200 ha over a disyance of 10000m or 10 km. Repeat the monitoring of these positions around three times.
Work it thru. Allow time for line cuutting of permanent grid type pattrrn adjusted for catchment shape. It had been done before and should become a fully formalised system elsewhere.
