An update to: Large wood is good.
This is what large woody debris installation for estuary restoration looks like. It was just a straight channel of water just a few weeks ago – not much more than a large ditch. No, it is not exactly “natural conditions” as it is probably only a fraction of the wood that was originally there and the logs are cabled in place. But this does restore some structure and function to the estuary that has been missing for the past 100+ years. At high tide, when the woody debris is submerged, it will provide refuge habitat for fish and additional habitat complexity. A secondary side channel was also added.
Special thanks must go out to the crews led by the BCIT Rivers Institute that worked 2 weeks of long nights at Lynn Creek estuary in North Vancouver to bring back a little bit of nature to the city.
