I have ferreted and lamped at Malham,excellent place or it was then,lifting with rabbits,we even had mooches around in daylight letting the dogs pick them from their seats or run them into the grikes and clints,Gary Hosker was the one who first highlighted the massive amount of rabbits if I remember correctly,I am sure many here remember his tales of rabbiting the limestone with his beddie/greyhound "Spud"
