“Is this it?” asks Lianna Teeter, a researcher from Fisheries and Oceans Canada’s Institute of Ocean Sciences in Victoria. In her hand she holds a small braya, an Arctic plant in the mustard family.

On this September day, we’re towards the end of the 11th leg of the historic Canada C3 expedition to celebrate Canada’s 150th anniversary. Our leg’s group, approximately 60 Canadians from across the country, is part of this coast-to-coast-to-coast ocean journey of reconciliation, unity, diversity, and science.

A small team of us have landed and are searching for an endangered plant species, the hairy braya (Braya pilosa).

“Close, but not quite,” I reply to Lianna. The specimen she found, a different species of Braya, still goes into a plastic bag that we’ll take back to our ship, the Polar Prince, for pressing.

Our search team, a handful of expedition scientists and other participants, goes back to exploring the muddy plateaus of Baillie Island, just off the tip of Cape Bathurst on the Northwest Territories mainland.

This is the only place on the planet the hairy braya is known to exist, but we don’t find it that day.

We do however witness the dramatic erosion of the shoreline into the sea, a stark reminder of the rapid climate change that is threatening species, and a way of life, across Inuit Nunangat, the Inuit homeland.

However, just the day before our hairy braya search, we did find a different rare species near the tip of Cape Parry, the peninsula immediately to the east of Cape Bathurst.

Just over the hill from our landing spot, growing in cracks spreading across the mud, we found the Arctic orangebush lichen (Teloschistes arcticus).

This rare lichen is known in Canada only from this particular area in the Northwest Territories.

The specimen we take for the Canadian Museum of Nature’s collection will document the species’ existence in the Canadian Arctic in 2017, just as all the botanical collections made on C3 will serve as part of a scientific legacy for this epic voyage.

Quanaqqutit to our amazing hosts in Nunavut and the Inuvialuit Settlement Region!
