This document summarizes knowledge and experiences in forest management as a response to climate change, based on a literature review and a survey of forest managers. This is part of an FAO-led process to prepare climate change guidelines for forest managers. It examines climate change impacts on forests and forest managers throughout the world. The document also reviews the main perceived challenges that climate change poses to forests and their managers. It summarizes experiences in preparing for and reacting to climate change in different types of forests. Finally, it indicates a number of gaps in enabling conditions (related to knowledge, institutional setting and culture) that hamper forest managers from responding effectively to climate change and its impacts
