If we’ve reached the point where we’re fretting over barnacles being knocked off by drift logs, perhaps we’ve run out of real crises. A recent University of Victoria study warns that wandering logs — nature’s most passive travellers — are scraping B.C.’s intertidal ecosystems into oblivion. …I mean no disrespect to my academic descendants at UVic — my alma mater — but I can’t help recalling a time when a scientist would distinguish between data and drama. Anyone raised on this coast knows those “thundering” drift logs are as much a fixture of our marine landscape as kelp, rockweed, and yes, barnacles themselves. …Here lies the problem with this kind of “drive-by ecology.” A barnacle count taken on a single day, at a single beach, photographed from orbit, becomes a sweeping “coast-wide phenomenon.” Probability alone tells us that the fraction of shoreline ­simultaneously blanketed and agitated by free logs — especially those resting on sand — is marginal.
