The report by NFU Cymru points to a number of possible reasons for the increase in the problem of abandoned horses and fly-grazing:-
- irresponsible breeding and a few unscrupulous dealers
- lack of grazing on highway verges
- effect of the recession on pet owners
- introduction of compulsory horse passports and micro chipping, which was intended to increase the traceability of horses, has added to the cost of keeping horses.
