The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. The Red Data Book categories provide an easily and widely understood method for highlighting those species under higher extinction risk, so as to focus attention on conservation measures designed to protect them. This document, incorporating changes recommended by IUCN members, was adopted by the IUCN Council in 1994.
Both Agenda 21 and "Caring for the earth : a strategy for sustainable living" recommend that every country should undertake a National Sustainable Development Strategy in order to mobilize and focus society's efforts to achieve sustainability. This book shows how the task can be approached, drawing on a wide range of national Conservation Strategies, Green Plans, Environmental Action Plans, sectoral plans such as Forestry Action Plans and comparable exercises throughout the world.
