An artcile in the Oceanside Star discussing the information presented at the MVIHES hosted 2010 Protecting Our Waterfront Speaker Presentations. From the article:
Harriet Rueggeberg, a biologist and planner for the Green Shores Technical Team, said shorelines are most impacted by population growth, waterfront development and climate change.
"Coastal shores are amazing places, biologically speaking," she said. "We have to be careful about how we build on the shoreline."
To build something, people remove vegetation, she said. This creates bank instability, so they build a seawall. This hardened shoreline actually makes the waves stronger, increasing erosion and creating a spray of seawater onshore that kills more vegetation.
Climate change is exacerbating this problem because, even if sea levels aren't rising dramatically (and they are in some places, such as Haida Gwaii), storm surges are becoming more violent.
"The best strategy may be to retreat," she said, "as opposed to spending money."
Remember, nature always wins!
