I want to thank the committee for inviting me to Ottawa to testify and for the opportunity to address this important topic, and for continuing to look at this issue, when there are so many other urgent issues, especially on the international stage. The long-term, important things must not be ignored.
I'm a professor of geography, biology and earth sciences at Memorial University, where I've taught since 2001. I was a co-founder of two relevant research groups at MUN: our deep-sea corals research group and our marine habitat mapping research group.
I've had the privilege of working in all three of Canada's oceans, focusing on deep-sea corals and marine habitat mapping. I've had the privilege to work in, and with, coastal communities in the Arctic and in my home province of Newfoundland and Labrador.
I've also taught conservation biology and geography since 2002, so I feel comfortable with that discipline and how it applies to marine and coastal systems and to some of the marine conservation science and policy issues in Canada.
As a way to get into the specific questions that you might ask, I want to show you some of the animals that Canadian marine protected areas and conserved areas protect and conserve.
The skeletons you're holding are from animals, three different species of deep-sea corals that occur in Newfoundland and Labrador waters, and similar species occur in all three of Canada's oceans.
Each of the samples you are holding is from an animal that lived for longer than any of us in this room. We know how long they can live. The popcorn coral has concentric rings that look like tree rings, and they're growth rings. That species can live up to 600 years, but most of the samples we get from bycatch or research collections are about 70 to 100 years old. In B.C. waters, this coral is known as the red tree coral, and that's one of the species that Mr. Dovey referred to in the previous session.
In addition to knowing how long the individual animals can live, we know that some of these species build habitats in Canadian waters that have been continuously occupied by corals for more than 2,000 years. For example, the bamboo coral is growing in the Disko Fan marine refuge in Baffin Bay. The third one is the bubblegum coral. It reaches heights of two to three metres. It can live, again, for up to 100 years. The oldest sample that we aged in particular, a medium-sized one, was 70 years old.
These coral species live a long time and they grow very slowly, and they build habitats that other animals rely upon. They're highly sensitive to fishing impacts. We know that the first pass of a trawl does the most damage to these highly sensitive habitats but, also, we often don't know where they occur until we encounter them with fishing gear. I'll send a PDF copy of this report we published a number of years ago about mapping the distribution of deep-sea corals in Newfoundland and Labrador's waters based upon fisheries bycatch from the fisheries observer program and the DFO research trawls.
We also know that all kinds of bottom-contact fishing gear, when deployed in coral habitats, will damage the corals. Obviously, bottom trawls, because they cover the most area, cause the most damage, but gillnets, bottom longlines and even crab pots cause coral bycatch, especially when they are dragged across the bottom during haulback.
Deep-sea corals are one of the vulnerable marine ecosystem indicator species recognized by the UN FAO and by UN General Assembly resolution 61/105, which required Canada and other coastal states to identify and protect VME species and habitats.
I want to use my experience with corals to address the questions you've asked.
With regards to impacts on coastal communities, I'm not a social scientist, so I don't work on the economic impacts of marine and conserved areas. What I will do is relate some of my experiences with seeing how reserve design has taken into account those impacts, sometimes to the detriment of the effectiveness of the research.
We need to protect marine biodiversity, but not just for the fish. We want and need to protect healthy oceans, as our BC Seafood Alliance people said, so we can have marine biodiversity and marine fish in the future, and I think everyone agrees upon that. In the oceans, just as on land, it's important to remember that protected areas are not one-size-fits-all. Stephen Woodley here is going to describe the IUCN. There are many different categories of protected areas ranging from strict closures to ones that are actually managed for resource exploitation with biodiversity as a secondary concern.
