April 18, 2012 - Session developed by Dominick DellaSala (Geos Institute). Presentations by Gordon Orians (U. of Washington), Paul Alaback (U. of Montana), and Ken Lertzman (Simon Fraser University)

Session Abstract: This session focuses on the world's coastal temperate rainforests in time and space from the Earth's deep past to the present state. It then focuses on the global significance of temperate rainforests. Representing only 2.5% of the world's forests (243 million acres) these remarkable rainforests are among the most carbon dense ecosystems on the planet, are exceptionally productive (due to marine, freshwater, terrestrial, tidal-glacial ecotones), have extraordinary levels of lichen richness (more than the tropics), and contain unusual species found nowhere else on earth (many plants, lichens, invertebrates, amphibians, birds, and fish). Temperate rainforests are found in only 10 regions of the world, mostly along coastlines but not exclusively (e.g., Inland Northwest North America and Inland Southern Siberia). Northern hemispheric rainforests tend to be more similar to each other than those in the Southern hemisphere. Northern hemispheric rainforests, with Tertiary affinities, share remarkable similarities in lichen composition. Southern hemispheric rainforests (Valdivia, Australasia, South Africa) share many similar tree genera due to ancient Gondwana affinities. This session will provide a global synthesis of the importance of temperate rainforests setting the tone for why the Pacific coastal rainforests - the most significant concentration of temperate rainforests in the world - are so vital regionally and internationally.

This video is from a symposium in Juneau, Alaska from April 17-20, 2012 titled Coastal Temperate Rainforests: Integrating Science, Resource Management, and Communities. The Alaska Coastal Rainforest Center (ACRC) would like to thank all sponsors, speakers, and participants for making the symposium a success.
