Great graphic...Herring are worth more in the water than in nets. Herring are most valuable to British Columbia as the foundation of the coastal ecosystem and herring contribute more to British Columbia’s economy by feeding other species than by being caught and processed. Better management of herring populations is an investment in the B.C. economy. Many of the fish species that eat herring sustain coastal economies through enabling commercial and sport fisheries. In 2016, the B.C. sport fishing industry employed 9,000 people and generated approximately $1.1 billion in gross revenue. Further, the whale populations that rely on herring, like humpbacks and orcas, draw hundreds of thousands of tourists to B.C. Marine-based recreation contributes over $4.3 billion to B.C.’s economy annually (2014). Meanwhile, the herring fishery generated approximately $19 million in 2019.Revenue generated by B.C.’s commercial salmon fishery decreased by more than $44 million from 2016 to 2019. This indicates that salmon populations are not what they once were, either. By protecting herring—Chinook salmon’s primary food source—we are also supporting salmon populations.Photo by Kali WexlerSources: ~ Fisheries and Oceans Canada~ BC Ministry of Agriculture~ David Suzuki Foundation ...

Nice to see some signs of hope given the decimation of so many starfish species. A virus was suspected, although more recent research suggests that higher organic matter due to ocean conditions increases microbial activity, which in turn depletes oxygen in the water and this causes respiratory distress and ultimately death in starfish. Climate change may exacerbate the problem as the microbes thrive in warm waters with high nutrients and warm water also holds less oxygen. The researchers involved in this study don't think they have all of the answers yet, but are looking at the problem differently now.www.nsf.gov/discoveries/disc_summ.jsp?cntn_id=301954&org=NSF&from=news#:~:text=As%20bacteria%20co.... www.frontiersin.org/articles/10.3389/fmicb.2020.610009/full ...

Seagrass meadows have tremendous biodiversity value and are also commonly believed to mitigate ocean acidification due to their high productivity and organic carbon. More research is needed to understand the full magnitude and timescale of potential buffering effects. In the case of the California coast, an extensive study involving seven seagrasses over six years found that to varying degrees and with seasonal differences, the seagrasses studied did indeed provide buffering capacity. One counterintuitive finding is that they even did so at night when there is no photosynthesis and the plants are respiring. ... See MoreSee Less

On top of the potential impacts on the Salish Sea, it makes no sense to build for a future we do not want and must not create. Canada has some decent climate policy in place - we just need to ratchet up the ambition so the transition happens more quickly. The rate of transition matters because the longer we delay, the more long lived carbon pollution accumulates in the atmosphere. ... See MoreSee Less

A good article. The challenge is convincing people to remove these structures. ... See MoreSee Less

Close to 30% of Puget Sound's shoreline is armored with seawalls and other structures meant to protect beaches against rising tides and erosion. But science increasingly shows that these structures are ineffective and cause significant harm to salmon and other creatures. State and federal agencies have been encouraging private property owners to remove armoring in a race to improve habitat, but why did so much of it start appearing in the first place?

It's certainly my experience, although it applies to much more than just species of birds. Imagine living in a world without our more than human kin. Of course, we humans are part of the web of life too and as Aldo Leopold said so well many years ago in reference to our impact on other species: “The last word in ignorance is the man who says of an animal or plant, "What good is it?" If the land mechanism as a whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering.” ... See MoreSee Less

Kelp forests change over time. Ocean conditions, predation pressures, large storms—these can all affect how much kelp we see from year to year. Tracking this change is key to understanding how kelp is doing across the massive BC coastline, and satellites are a key tool scientists use to track trends.Landsat satellites have been taking pictures of the BC coast every 16 days since 1984, and capturing a lot of potential photos of kelp forests in the process. But even when cloudy days (the nemesis of coastal mapping) are filtered out, 35+ years of data is still too much to handle.That’s where the Google Earth Engine Kelp (GEEK) Tool comes in. It helps narrow this huge amount of data down to the most useful photos. To see it in action, check out the GEEK Tool ArcGIS StoryMap created by Hakai geospatial scientists Luba Reshitnyk and Will McInnes: storymaps.arcgis.com/stories/f29e19c6b23a4227a5eca87edb61ea97The scientists who developed this newly-launched tool are looking for feedback to make it even better, and you can help! Local historical knowledge helps refine the GEEK tool’s algorithm. So where are the BIGGEST kelp forests—either giant or bull kelp—you’ve seen in British Columbia? When did you see them?
