Book Synopsis Seeds of Restoration Success by : Sara F. Oldfield
Download or read book Seeds of Restoration Success written by Sara F. Oldfield and published by Springer Nature. This book was released on 2019-09-25 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general overview of the natural landscapes and vegetation types of the U.S., the key plant species that help define them, the pressures faced by natural ecosystems and the imperative for conservation and restoration. It addresses the policies that have been introduced to manage healthy ecosystems and the practical progress that is being made in restoration. A particular focus is on the production of diverse native plant materials currently required by the National Seed Strategy. Case studies demonstrate how native plant materials are essential to support the conservation of healthy ecosystems with their biodiversity and functions as well as supporting a productive and sustainable agricultural sector and healthy ecosystems for all. The authors are closely connected with major national and international networks of botanic gardens, ecologists and conservation scientists at Board level and through other professional links. Condensing a wide range of current information into a concise format, this book fills a need by experts and informed amateurs interested in the natural environment, including gardeners, botanic garden and protected area visitors, government agencies, the private sector native seed industry, and NGOs.
