Rabbits cause an enormous amount of damage every year to crops, railways, nurseries, gardens, golf courses, runways, motorways, cemeteries etc. Recent DEFRA estimates put rabbit damage at £10 per annum, per rabbit to cereal and equivalent crops and there are estimated to be around 40 to 50 million wild rabbits in Britain at present, with the population growing year on year. Other estimates state that 10 rabbits will eat the equivalent amount of grass to 1 sheep.
