The central aim of this publication is to consider the key elements of a modern, comprehensive, and effective legal framework for successful management of protected areas. They provide practical guidance for all those involved in developing, improving, or reviewing national legislation on protected areas, be they legal drafters and practitioners, protected area managers, interested NGOs, or scholars. These guidelines include fifteen case studies, eight dealing with the protected area legislation of individual countries and six cases dealing with specific sites providing fundamental solutions that stand the test of time.

IUCN's Protected Areas Management Categories, which classify protected areas according to their management objectives, are today accepted as the benchmark for defining, recording, and classifying protected areas. They are recognized by international bodies such as the United Nations as well as many national governments. As a result, they are increasingly being incorporated into government legislation. These guidelines provide as much clarity as possible regarding the meaning and application of the Categories. They describe the definition of the Categories and discuss application in particular biomes and management approaches.

This is an updated edition of the 1995 version. In the mid-1980's, the IUCN CEL, in consultation with leading experts from around the world, began to respond to a need later identified by Agenda 21: the preparation of an integrated framework for international environmental law.
