The two pest plants covering the greatest area along the Whatatiri are gorse and blackberry. The former is often straggly and not a problem along the bush part, but there are large over 2 m high gorse over 50 m or so of the track at about baitline LeA.
Very common on the disturbed areas beside the tracks.
