then they move back out to sea. the wildlife presenter steve backshall has dived here, and says boat anchors and mooring chains can damage the sea bed. they completely destroy all the substrate around it, which means that all the seagrass dies, and it gets rid of that binding substrate, which then washes away as sand. and so you just end up with these big, barren circles around all the moorings. and within that, nothing can live and particularly not seahorses. so here s a solution. the seahorse trust is installing this environmentally friendly design. instead of a chain, the mooring is attached to a fixed point in the sea bed via a large rubber line that stretches with the tide and minimises damage. divers put this screw anchor into the sea bed. it goes in around seven feet deep, into the sea bed, then connected to these rubber pieces here thick, dense rubber.
famously, it s the male that gets pregnant. it s a protected species, and studland bay is a marine conservation zone. but boats in this popular area of the dorset coast can create problems. we ve counted up to a50 boats here in one day. it s the noise, the anchors, the general movement of everything seems to affect the seahorses. they re very prone to stress, and so if you can sort of reduce that stress then they re quite happy, relaxed seahorses. if they have a lot of stress, then they move back out to sea. the wildlife presenter steve backshall has dived here, and says boat anchors and mooring chains can damage the sea bed. they completely destroy all the substrate around it, which means that all the seagrass dies, and it gets rid of that binding substrate, which then washes away as sand. and so you just end up with these big, barren circles around all the moorings. and within that, nothing can live
