Paul Hessburg: "Historical and Current Fire Regimes of Eastern Washington-
How Did We Get Here?"
Dr. Hessburg will characterize historical fire regimes and how they affected the E WA landscape. He will then show how 20th century management inadvertently altered the structure, composition, and patterns of forests, and how this has led to significant changes in the fire regimes of each major forest type. He will show how a warming climate, increased fuels, and a virtual epidemic of young trees have created a “perfect storm” condition for today’s wildfires. He closes his talk by showing how the study of historical landscape functioning gives us important clues to how we might restore our modern era landscapes.
Dr. Hessburg is a Research Landscape Ecologist with the USDA-Forest Service, PNW Research Station. He is stationed in Wenatchee, WA, where he has lived and worked for the last 27 years. Paul is also Affiliate Professor at the UW, WSU, and UI where he has graduate students and collaborative research projects with faculty post-docs. His areas of research interest are the landscape and disturbance ecology of historical, contemporary, and future western US forests under climate change, natural wildfire resilience mechanisms of western forests, and the ecology and sociology of landscape restoration. He has 38 years of professional forestry experience in the West, has authored and co-authored >175 research articles and book chapters, including a recently released Springer title on decision support modeling in natural resource management.
Robert Van Pelt- "The Forests of the Olympic Peninsula"
Dr. Van Pelt van has long been fascinated with “Forest Giants” and has extensively studied old-growth forests across North America, particularly in California and the Pacific Northwest. He has a particular interest in tree and forest structure and forest ecology. He has a long connection with the forests of Washington State and was responsible for starting the Washington Big Tree Program in 1987, which keeps records on the largest of each species of tree in the state. He is currently involved in canopy research in the forests of the Olympic Peninsula, among other sites, and will share recent findings with us.
Dr. Judith Harpel- "The Moss Flora of Washington"
Dr. Harpel is currently the Curator of Bryophytes at the University of British Columbia, Beaty Biodiversity Museum, Museum Research Associate with the University of Washington, Burke Museum and a Research Associate with the California Academy of Sciences. She has been working on bryophytes for the last 38 years and studied the ecology and phytogeography of the mosses within the San Juan Islands, Washington for her Ph.D. For eight and half years she was the U.S. Forest Service Regional Interagency Bryologist and provided bryophyte training and guidance for U.S. Forest Service and Bureau of Land Management botanists in Washington, Oregon and California.
Dr. Dennis Paulson- "Birds and Plants"
Everyone knows that birds come to feeders full of seeds. There are a lot of seed-eating birds! But birds relate to our native plants in many more ways than that, both positive and negative, and Dennis Paulson will tell you about this in an illustrated lecture.
Dr. Paulson, recently retired as Director of the Slater Museum of Natural History, University of Puget Sound, and has been a professional biologist and naturalist all of his adult life. He began studying natural history as a boy and is a world expert on dragonflies and shorebirds, in addition to teaching master birder classes for the Audubon Society. He is the author of nine books, including Shorebirds of North America and Dragonflies and Damselflies of the West, and 90 scientific papers on birds and dragonflies.
Ed Alverson- The genus Erythronium in Western North America
Western North America is the global center of Erythronium diversity, with 22 of the 33 species found worldwide. Ed has spent the last several decades roaming in search of fawn lilies, avalanche lilies and their kin.
The Western species exhibit a wide range of flower color and leaf form, and under optimal conditions, they can form large colonies. While some of these species are widespread, many are localized endemics.
Ed will show photos of both the common and the rare species, and share some of what he has experienced from his wide-ranging explorations.
