Of 5,981 agricultural holdings, more than half were between 5 and 50 acres. Pembrokeshire had a flourishing wool industry. There are still working woollen mills at Solva and Tregwynt. Pembrokeshire has good soil and benefits from the Gulf Stream, which provides a mild climate and a longer growing season than other parts of Wales. Pembrokeshire's mild climate means that crops such as its new potatoes (which have protected geographical status under European law) often arrive in British shops earlier in the year
