Since 1998, volunteers from Sea Change Marine Conservation Society have been restoring watersheds from the lower mainland to Hyde Gwai. Their work involves everything from cleaning up shorelines, educational nature walks for the public, maintaining nesting boxes for endangered birds, and even under sea gardening. Here's the Cooper. This is a marine flag most of us living on the West Coast recognize, it means caution diver below. Or in this case, gardener below. What we're doing is taking eel grass from the healthy bed, which is just right in front of us here and putting it out into areas where it's completely gone. Eel grass grows in shallow water forming meadows on the seafloor. It slows wave action to prevent erosion of sand from our shorelines and provides food and shelter for everything from crabs to salmon. Our salmon need eel grass from when they are coming down the streams before they hit open ocean. They need to spend a couple months in the estuary to get bigger. So the eel grass is the primary place where they are able to gather their food and hide. But it's disappearing. The Couchin Bay has very little eel grass left. Hundred years of logging and human recreational use in the estuary has wiped out in almost entirety. But so for the past decade, volunteers from sea change marine conservation society have been restoring eel grass beds. Gently removing just enough shoots to leave current beds healthy and plant new ones. We put the little washer on here just up beyond where the last lot of roots are. Eel grass shoots actually float. So the anchors are needed to hold them down and the divers plant them so the anchors are just underwater. And they plant them in clumps of 10 shoots, one meter apart. So is it working? The education piece has been very successful. A lot of the volunteers have never heard of it before and just want to help out in the Couchin Bay area. Restoration is difficult. It's better to conserve what we already have than to try and restore what's already gone. It has been very successful in the past. Some of the old statistics show 80 percent growth from a planted bed. But this dive brought a disheartening discovery. Transplant sites from 2008 and 2009 were gone. There were no no shoots left, just metal washers. It might have been geese eating the shoots, extreme low tides drying them out or human intervention. C-Change will try to get to the bottom of why they lost all those beds and keep working to reestablish this important plant habitat.
