Drift Wood Mapping
As part of the ShoreKeeper program, ES students have mapped the location of each drift log found near the high tide line. These are referenced to an established permanent baseline. By annual or biannual surveys, students are able to demonstrate the extent to which the shoreline dynamic or static.
The ShoreKeepers maps at Booth Canal on SaltSpring Island show dramatic movement over winter periods but considerable stability over the summer periods. These changes are linked to storm events from the North West associated with extreme high tides.
This information has been shared with local residents because it addresses concerns about shore line stability. The concrete abutment at the base of the stairs used to access the beach has needed repair because these significant storm events have threatened to undermine the concrete footings. More effective footings tied to bedrock seems to be needed.
