A great deal of additional information on the European Union is available on the Internet. It can be accessed through the Europa server (http://europa.eu.int) Cataloguing data can be found at the end of this publication Luxembourg: Office for Official Publications of the European Communities, 2005 © European Communities, 2005 Reproduction is authorized provided the source is acknowledged Printed in the European Union Identification of “hot spot areas” of forest cover changes in boreal Eurasia II Abstract A group of experts convened in Moscow in April 2004 at the invitation of the Joint Research Centre and the network of the Global Forest Watch Russia, aiming to identify and locate current and potential areas of rapid forest cover change in boreal Eurasia. This report presents the resulting “hot spot” maps of the boreal European and Siberian regions. The “hot spot areas” were delineated based on data uniquely available to the participants and experts, who were drawn from different parts of the country and were highly qualified and very knowledgeable about forestry activities and changes in forest cover. While this approach does not directly lead to quantified estimates of forest changes, it highlights in a regional context those areas where forest cover changes are concentrated and where close monitoring would be required for an estimation of the changes at continental scale. In addition to the mapping of areas of current or impending change in forest cover (the so-called “hot spot areas”), the group aimed to characterize the main drivers of these changes. During the months following the expert consultation the information compiled by the Russian experts’ was complemented with the help of a larger expert community in order to cover the boreal forest zone of the whole Eurasian continent. During the consultation, we also collected information on potential criteria for an automated delineation and stratification at a broad scale. Such information includes forestry statistics (status and trends), burned areas, access networks, etc. Information on the location of active fires, which can be derived from satellite Earth observation data, was considered a useful indicator for the Siberia region. The use of these spatial indicators should be further developed to allow a more automatic identification of hot spot areas in future spatial modelling exercises. It is understood that this information is subject to revision. The results of this study are considered to be an important initial step for the development of a new method of monitoring the boreal forest cover of the Eurasian continent.
