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.

Dateiformat: PDFKopierschutz: Wasserzeichen-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat PDF zeigt auf jeder Hardware eine Buchseite stets identisch an. Daher ist eine PDF auch für ein komplexes Layout geeignet, wie es bei Lehr- und Fachbüchern verwendet wird (Bilder, Tabellen, Spalten, Fußnoten). Bei kleinen Displays von E-Readern oder Smartphones sind PDF leider eher nervig, weil zu viel Scrollen notwendig ist. Mit Wasserzeichen-DRM wird hier ein „weicher” Kopierschutz verwendet. Daher ist technisch zwar alles möglich – sogar eine unzulässige Weitergabe. Aber an sichtbaren und unsichtbaren Stellen wird der Käufer des E-Books als Wasserzeichen hinterlegt, sodass im Falle eines Missbrauchs die Spur zurückverfolgt werden kann.
