A key component in healthy ecosystems, lichens can be found in almost any natural habitat in the Pacific Northwest. This comprehensive guide to the region’s macrolichens is intended for use by beginners as well as specialists: weekend naturalists will be able to identify specimens and recognize the great diversity of lichens, while lichenologists and mycologists will gain greater knowledge of the distribution and abundance of various species.

This revised and expanded edition of Macrolichens of the Pacific Northwest includes 116 new species and 176 additional illustrations and incorporates an understanding of macrolichens that has advanced tremendously in the past decade.

Macrolichens of the Pacific Northwest includes keys to 113 genera and 586 species of Oregon and Washington macrolichens—all the macrolichens known or expected to occur in the two states. The keys also provide reasonable coverage for lichens of Idaho and Montana, inland to the Continental Divide. Color photographs and detailed descriptions are provided for 246 species, emphasizing lichens prevalent in forested ecosystems.

The illustrated glossary and introductory material cover the terminology needed to identify macrolichens and provide information on collection and handling. The biology, ecology, and air-quality sensitivity of lichens are discussed; regional air-quality sensitivities are provided for 184 species.

Macrolichens of the Pacific Northwest will prove invaluable to anyone seeking to identify lichens or to better understand these organisms and their vital role in the natural world.

Medicines That Feed Us examines the relationship between toxicity and remedy in the face of the intertwined health and environmental crises that are shaping life in the twenty-first century. Through ethnographic work with organizations that use plant-based healing and sustainable farming practices in Tanzania, Stacey A. Langwick asks what it means to heal in a toxic world. Expanding on the Kiswahili phrase dawa lishe, or medicines that feed us, Langwick describes the potency of plant medicines in therapeutic projects that address bodies and environments together. These efforts challenge biomedicine’s intense focus on the internal dynamics of biological bodies and its externalization of the modern agricultural, industrial, and land management practices that impact it. Dawa lishe is not a call to return to the traditional, but an invitation to join contemporary experiments in how we know, use, and govern therapeutic plants. Medicines That Feed Us offers alternative ways of living and dying, growing and decaying, composing and decomposing which acknowledge the interdependence of bodily and ecological health.

Now in its tenth decade of publication, Michigan Trees has been, since it was first introduced in 1913, the must-have reference book for anyone who wants to know about the trees of this unique North American region.

In this new and updated edition, several new species have been added to the lineup, as well as sections on tree ecology and fall color. Written and illustrated in a style that appeals at once to academic botanists and armchair arborphiles alike, Michigan Trees gives readers everything they need to know for identifying trees in the Great Lakes state. Included with each description are fascinating notes and asides (for example, this tidbit on the jack pine: "Parklike or savanna stands in north-central Michigan are prime habitat for the rare Kirtland's warbler that breeds nowhere else in the world."). Also includes a tree key and identification section illustrated with elegantly simple line drawings that reveal the tiny, signature details that make each tree unique.

Burton V. Barnes is Professor of Forestry at the University of Michigan. Formerly a research forester, he is best known for his research and publications in forest ecology and forest genetics.

Moveable Gardens explores how biodiversity and food can counter the alienation caused by displacement. By offering in-depth studies on a variety of regions, this volume carefully considers various forms of sanctuary making within communities, and seeks to address how carrying seeds, plants, and other traveling companions is an ongoing response to the grave conditions of displacement in today’s world. The destruction of homelands, fragmentation of habitats, and post-capitalist conditions of modernity are countered by thoughtful remembrance of tradition and the migration of seeds, which are embodied in gardening, cooking, and community building.

Moveable Gardens highlights itineraries and sanctuaries in an era of massive dislocation, addressing concerns about finding comforting and familiar refuges in the Anthropocene. The worlds of marginalized individuals who live in impoverished rural communities, many Indigenous peoples, and refugees are constantly under threat of fracturing. Yet, in every case, there is resilience and regeneration as these individuals re-create their worlds through the foods, traditions, and plants they carry with them into their new realities.

This volume offers a new understanding of the performances and routines of sociality in the face of daunting market forces and perilous climate transformations. These traditions sustained our ancestors, and they may suffice to secure a more meaningful, diverse future. By delving into the nature of nostalgia, burrowing into memory and knowledge, and embracing the specific wonders of each deeply rooted or newly displaced community, endlessly valuable ways of being and understanding can be preserved.
