Timothy Walker writes a collection of essays to advocate recognition of plant conservation work. The book is organized into four parts with thematic chapter essays thereunder. The book also includes a "further reading" bibliography, an "organizational websites" bibliography, conversion tables, and an alphabetical subject index. The four parts include: "The Global Garden List"; "Oath of a Plant Steward: To Conserve and Protect"; "And Justice for All: Diversity without Adversity"; and "What Can You Do? Partnership and Practice in Plant Conservation". Although this 2013 UK book does include some reference to UK-specific contexts and the 2020 Global Strategy for Plant Conservation, the majority of the book's contents are still relevant and will continue to matter. Also, for a science advocacy book, the layout design is remarkably impressive and that work deserves recognition. While some novice subject readers might be overwhelmed by the scope of the book's contents, most interested readers should enjoy the easily accessible prose and the convincing, complementary, arguments for why (and how) plant conservation matters to the future of plants and humans.
