Harvesting wild berries, firewood, and other non-timber forest products (NTFPs) from the boreal forest in Interior Alaska is a common activity amongst local residents. NTFPs are harvested for personal use, subsistence, and commercial purposes. While these activities contribute to informal household economies and livelihoods, harvest of NTFPs are not well documented in Alaska. Availability of these ecosystem services may be altered under changing management and climate regimes. This interdisciplinary dissertation takes a look at the activities and impacts of current NTFP harvesting practices. Survey results from a forest use survey provide insight into harvest activity in the Tanana Valley. Wild blueberries (38.5% of households with mean harvested amount of 7.7 quarts) and firewood (25.0% of households with a mean harvest amount of 4.7 cords) were reported harvested with greatest frequency, and harvesting activities were mostly concentrated around larger population centers. Interviews were conducted with personal use and subsistence NTFP harvesters from Interior Alaska. Participants enjoy harvesting from the forest, and that the importance of harvesting is a combination of both the intangible benefits from the activity and the tangible harvested items. Harvested NTFPs were seen as high-quality products that were otherwise unavailable or inaccessible. Birch syrup is a commercially available NTFP produced in Alaska by a small number of companies. Similar to maple syrup, producing birch syrup is a labor intensive process with marginal profits. Interviews were conducted with workers in the Alaskan birch syrup industry, who reported that they were seeking an alternative to the traditional employment. The effects from mechanical damage from tapping for spring sap on birch's vigor are of concern to birch syrup producers and natural resource managers. This study compared the annual increment growth of Alaskan birch trees, Betula neoalaskana, between tapped and untapped trees. No significant difference was detected from tapping, but annual variability in growth was strongly significant. A temperature index accounted for nearly two-thirds of the annual variability. Pairing this index with two climate scenarios, birch growth was extended out through the 21st century. As temperatures rise, birch in Interior Alaska are projected to face a critical threshold, which may limit or extinguish their ability to sustain growth and yield a sustainable sap resource. Integrating the survey, interview, and dendroclimatological data provides a richer picture of how NTFP harvesters actively use the forest and about the benefits derived. These findings can assist resource managers in balancing these needs with those of other forest uses on public land.

Winner of the Skipping Stones Honor Award in the Ecology and Nature Books category The boreal forest is the last great forest wilderness on earth. It drapes across the subarctic right around the world. It pervades our myths and folklore. It provides us with wood and water. It freshens the very air we breathe. Jane Drake and Ann Love take the reader on an unforgettable journey around the world to view the boreal forest. They show the reader the seasons in the bush, the science and myth of wolves, the life cycle of the woods. From the Siberian Taiga, where tigers and sika deer live, to the Old World forests of Norway, from the Boreal Shield of North America to the birch forest of Northwest Russia, we are introduced to a region of incredible importance. Despite our reliance on it, we have placed the “lungs of the earth” under siege with clear-cutting, acid rain, and even radioactivity. Cool Woods is not only informative and beautiful, but it is a call to action to anyone who cares about our planet.

Elegant, rich in history, and supremely useful, birches have played an extraordinary yet largely unrecognized part in shaping both our natural environment and the material culture and beliefs of millions of people around the world. Exploring birches’ many uses, the ancient beliefs and folklore we associate with them, their abiding portrayal in literature and art, and their biology, Birch presents a fascinating overview of the cultural and ecological significance of these versatile trees. For thousands of years, birches have given the people of northern temperate forests and beyond raw materials in the form of leaves, twigs, branches, bark, wood, and sap—materials used not simply to survive, but to flourish and express identity in practical and spiritual ways. Tough, waterproof, and flexible, birch bark has been used for everything from basketry and clothing to housing, transport, musical instruments, and medicines, and even to communicate and record sacred beliefs: some of our most ancient Buddhist texts and other historic documents are written on birch bark. Birches have not only shaped regional indigenous cultures—for example, in the form of the Native American wigwam and the birch bark canoe—they also continue to be of global economic importance today. Featuring an arbor of illustrations and rich analyses, Birch is an enlightening look into the history and possible future of these beautiful trees.

The boreal forest is one of the world's great ecosystems, stretching across North America and Eurasia in an unbroken band and containing about 25% of the world's closed canopy forests. The Kluane Boreal Forest Ecosystem Project was a 10-year study by nine of Canada's leading ecologists to unravel the impact of the snowshoe hare cycle on the plants and the other vertebrate species in the boreal forest. In much of the boreal forest, the snowshoe hare acts as a keystone herbivore, fluctuating in 9-10 year cycles, and dragging along secondary cycles in predators such as lynx and great-horned owls. By manipulating the ecosystem on a large scale from the bottom via fertilizer additions and from the top by predator exclosures, they have traced the plant-herbivore relationships and the predator-prey relationships in this ecosystem to try to answer the question of what drives small mammal population cycles. This study is unique in being large scale and experimental on a relatively simple ecosystem, with the overall goal of defining what determines community structure in the boreal forest. Ecosystem Dynamics of the Boreal Forest: The Kluane Project summarizes these findings, weaving new discoveries of the role of herbivores-turned-predators, compensatory plant growth, and predators-eating-predators with an ecological story rich in details and clear in its findings of a community where predation plays a key role in determining the fate of individuals and populations. The study of the Kluane boreal forest raises key questions about the scale of conservation required for boreal forest communities and the many mammals and birds that live there.

"Betula papyrifera, paper birch, is native to the boreal forest, the earth’s largest land-based biome and our largest store of carbon. A pioneer species, paper birch is one of the first to grow after disturbances such as fire where their seeds are carried by the wind. Yet, due to global warming, boreal forest climate zones are moving north much faster than the trees can migrate. Paper birch trees have relatively short life spans but decompose slowly on the forest floor. Long after the inner wood has been recycled by insects and fungi, their water-resistant bark skins remain as hollow horizontal forms, vestiges of a bygone climate"--Paper wrapper.

For the last fifty years, the trees of the boreal forest have been moving north. Ben Rawlence's The Treeline takes us along this critical frontier of our warming planet from Norway to Siberia, Alaska to Greenland, Canada to Sweden to meet the scientists, residents and trees confronting huge geological changes. Only the hardest species survive at these latitudes including the ice-loving Dahurian larch of Siberia, the antiseptic Spruce that purifies our atmosphere, the Downy birch conquering Scandinavia, the healing Balsam poplar that Native Americans use as a cure-all and the noble Scots Pine that lives longer when surrounded by its family. It is a journey of wonder and awe at the incredible creativity and resilience of these species and the mysterious workings of the forest upon which we rely for the air we breathe. Blending reportage with the latest science, The Treeline is a story of what might soon be the last forest left and what that means for the future of all life on earth.

This comprehensive textbook explores the boreal forests of Northern Europe, Finland, Sweden and Norway. Students will gain an overview of the forest ecosystem and the services it provides for modern society. From the production of timber, to the supply of food products or their use as a recreational space for human wellbeing – our forests serve many needs. Accordingly, the respective chapters cover various types of ecosystem service, e.g. supporting, provisioning, regulating and cultural services. The book’s main focus is on the management of boreal forests for the production of these ecosystem services. Addressing modern challenges, e.g. managing vulnerable boreal forests for adaptation to climate change, is an important aspect throughout the volume. Traditional forest management has to adapt and evolve in order to meet the increasing risk of abiotic and biotic damages to our forest biomass. Future forestry graduates will have to face more and more of these challenges; consequently, the book provides them with a wealth of scientific knowhow and possible counter-strategies. Forestry students in the Northern Hemisphere, be it in Europe, North America or Asia, will find this book an excellent reference guide. To make the content more accessible, it has been enriched with a clear structure, numerous illustrations and learning objectives.
