Alright mate i would seem alittle bit of a "Novice" in trapping and snaring but personally i would walk your permission and look for really well used runs and set a snare where the rabbits are using and are going through at the right hight for your snare. With the live trap i would put it near a warren with some think foilage over the top to disguise it. As the rabbits investigate the area which is in their nature they will get used to investigating it and BINGO
Hope this helps
