I'd agree with that. I don't know off the top of my head head either.
I do know that there are maybe not jurisdictions, but other academics looking at different options for where you need to harden shorelines. Natural shorelines are always the best option in conserving that vegetation, but in instances where shoreline hardening needs to be done to stop erosion, people are studying different methods that can still provide shoreline stability but increase the biodiversity around it, as opposed to just riprap or a plain concrete wall.
