As a Project Fellow at SeaPlan, I am interested in the conversation among MSP practitioners over the pragmatic utility of ecosystem services tools for “real life” application. I recently looked at the role of modeling tools and platforms that quantitatively categorize zones or ecosystems services in ocean planning. This research led me to develop a broad overview of available valuation modeling tools and to detail some interesting example applications. I thought others would be interested, so SeaPlan is sharing them here as a series of three short case studies followed by the overview. First in this series is a case study summarizing how two of the most widely-used modeling tools, InVEST and Marxan, were applied by West Coast Aquatic (WCA) for the West Vancouver Island marine spatial plans.
