The Forest Focus regulation centered specifically on the monitoring of the effects of atmospheric pollution and fires on European forests, previously addressed by Council Regulation (EEC) No 3528/86 of 17 November 1986 on the protection of the Community's forests against atmospheric pollution and Council Regulation (EEC) No 2158/92 of 23 July 1992 on protection of the Community's forests against fire. Furthermore, “Forest Focus” aimed at encouraging the exchange of information on the condition of and harmful influences on forests in the Community and enabling the evaluation of ongoing measures to promote conservation and protection of forests, with particular emphasis on actions taken to reduce impacts negatively affecting forests. In order to promote a comprehensive understanding of the relationship between forests and the environment, the scheme also included the financing of studies and pilot projects aiming at the development of monitoring schemes for other important factors such as biodiversity, carbon sequestration, climate change, soils and the protective function of forests. The EC launched and financed a series of seven studies dealing with the following topics: 1. Climate change impact and carbon sequestration in European forests 2. Development of a simple and efficient method field assessment of forest fire severity 3. Use of National Forest Inventories to downscale European forest diversity spatial information in five test areas, covering different geo-physical and geo-botanical conditions 4. Harmonizing National Forest Inventories in Europe 5. Development of harmonised Indicators and estimation procedures for forests with protective functions against natural hazards in the alpine space 6. Linking and harmonizing the forests spatial pattern analyses at European, National and Regional scales for a better characterization of the forests vulnerability and resilience 7. Evaluation of the set-up of the Level I and Level II forest monitoring under Forest Focus. This study (topic 3 in the above list) aims at addressing and demonstrating the integration of two different data sources i.e. forest biodiversity variables available from National Forest Inventories (NFIs) in European countries and landscape level forest spatial pattern maps easily obtained from remote sensing based forest cover maps. This study addresses the link between the two data sources. It also includes the first concrete harmonization exercise of forest biodiversity variables available from National Forest Inventories (NFIs) in five countries.
