Book Description
Winner of the 2021 John Burroughs Medal for Distinguished Natural History Writing "This deeply nourishing book invites us to reclaim reciprocity with the living world." —Robin Wall Kimmerer, author of Braiding Sweetgrass Once, farmers and rural people knew how to prune hazel to foster abundance: both of edible nuts and of straight, strong, flexible rods for bridges, walls, and baskets. Townspeople felled their beeches to make charcoal to fuel ironworks. Shipwrights shaped oaks to make hulls. No place could prosper without its inhabitants knowing how to cut their trees so they would sprout again. Pruning the trees didn’t destroy them. Rather, it created the healthiest, most sustainable and diverse woodlands that we have ever known. Arborist William Bryant Logan offers us both practical knowledge about how to live with trees to mutual benefit and hope that humans may again learn what the persistence and generosity of trees can teach. He recovers the lost tradition that sustained human life and culture for ten millennia.

Book Description
We are causing species to go extinct at extraordinary rates, altering existing species in unprecedented ways and creating entirely new species. More than ever before, we require an ethic of species to guide our interactions with them. In this book, Ronald L. Sandler examines the value of species and the ethical significance of species boundaries and discusses what these mean for species preservation in the light of global climate change, species engineering and human enhancement. He argues that species possess several varieties of value, but they are not sacred. It is sometimes permissible to alter species, let them go extinct (even when we are a cause of the extinction) and invent new ones. Philosophically rigorous, accessible and illustrated with examples drawn from contemporary science, this book will be of interest to students of philosophy, bioethics, environmental ethics and conservation biology.

Book Description
A comprehensive practical manual for professionals and self-builders, this innovative book explains the many benefits of building with hempcrete. Hempcrete is a building material with excellent, environmentally friendly properties. It's made from lime and hemp shivs (a waste product from hemp fibre growing) and can be used for walks, floor and roof insulation. Hempcrete is breathable, absorbing and emitting moisture; this helps regulate internal humidity, avoiding trapped moisture and mould growth, and creating healthier buildings. It provides excellent acoustic and thermal insulation, and it is lightweight, which reduces construction costs. Whether you're working on a new build or are planning a renovation, The Hempcrete Book tells you everything you need to know to get started with hempcrete. It describes how to source and mix it, and provides a detailed account of construction techniques, highlighting potential pitfalls and how to avoid them. With fully illustrated design notes and examples of completed builds, this book is a powerful tool for any eco-builder.

Book Description
Temperate broadleaved trees grow in very different ecosystems in the northern and southern hemispheres, but are also found extensively in many tropical and subtropical mountain areas. A wide range of non-wood products are derived from temperate broadleaved trees, and their description is organized in this volume according to the part of the tree from which they are obtained (whole tree, foliage, flowers, etc.). This information is presented in order to raise awareness on, and assist in identifying, opportunities for the management and production of non-wood products from temperate broadleaved trees. The intended audience of this publication ranges from interest groups in the forest, agriculture and rural development sectors to conservation agencies in developed and developing countries.
