This detailed publication from the IUCN, in collaboration with global partners, provides guidance for terrestrial, marine, and freshwater protected area managers at both system and site levels on the restoration of natural and associated values of protected areas. It is very detailed but also easy to read. Key sections include Chp. 1 How to Use this Guide (pg. 1), Chp. 4 Best Practices (pg. 23), and Chp. 6 Case Studies (pg. 71). The case studies derive from around the globe and include the example of Lyell Island in Gwaii Haanas.
