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.

My presumption is you are talking about Doc type kill traps targetting mustelids and rats ?
Well if you think a trap every 2 ha will cover rats you have no chance. North Island forest , a male rat has a range of 1.1ha , females the range was down as low as 0.3 ha. That is a shit load of rats [particularly females] that will never even see your trap !

What density will you use on cats and type of trap ? Possums and type of trap ?
