The overall objective of SEMEFOR was to evaluate the hannonised and demonstrated satellite based methods for pan-European assessment of forest health. Currently, monitoring of forest health is conducted under EU-Council Regulations by field assessment in approximately 5500 plots with 15 to 25 trees in each plot. These plots are located in a grid system, the level I plot grid, generally with 16 km distance between plots. In each plot, tree defoliation and discoloration is monitored. Additionally, intensive monitoring is conducted in more than 800 Level II plots. In these plots also chemical analysis of the foliage and the soil is carried out together with several other measurements.

The pan-European monitoring organisation led by ICP-Forests has been very successful in creating a system that provides an annual and easily interpretable overview of the forest health situation in Europe. With the widely accepted fact that the forest decline problem was not as severe as first predicted, as well as the recognised need for long-term monitoring in times of climatic change, the discussions of the future of the inventory has been intensified. Reduction of the monitoring costs with smallest possible effects on quality and quantity has been requested, as well as modification of the survey to meet requirements associated with monitoring of sustainability and biodiversity factors. Both these main lines of suggestions have increased the attractiveness of remote sensing. .
