From Kelp Forests to Urchin Barrens Monday July 9, Heritage Centre, Skidegate 7:00 pm The ocean is the world's largest habitat, but marine ecosystems and their drivers remain a mystery to many people. Join visiting eminent ecologist Bob Paine and SFU's Anne Salomon for an exploration of the interconnectedness of life in the sea. Bob developed the concept of "keystone species" in a now-classic 1966 paper and is one of the world's best-known marine ecologists. Anne studied with Bob and has been conducting research in Gwaii Haanas for the past several years. They will have just returned from a research trip in Gwaii Haanas andwill share their reflections on the state of Gwaii Haanas' marine ecosystems and what we can do to ensure they continue functioning for generations to come.Tideline Timeline 11,000 years of human activity Wednesday July 11, Haida Heritage Centre, Skidegate 7:00 pm ??Obsidian, a carved object, stone tools and a preserved split wooden plank are just a few of the artifacts ?found over a six-week field season in Gwaii Haanas. Archaeologists have been working at three sites: Kilgii Gwaay, a forest site near Rose Harbour which provides some of the earliest evidence of human occupation on the coast (from 10,700 years ago); new terraced coastal sites at Burnaby Narrows where deep shell middens reveal what people ate 4000 years ago, and an intertidal zone in Skincuttle Inlet, where numerous fish traps, fish weirs and clam gardens were mapped.Dr. Quentin Mackie and Jenny Cohen of UVic will present the preliminary results of this productive research period in words and images. They share the stage with Gwaii Haanas' own Camille Collinson, for Archaeology 101, an account of her first adventure in this field.
