Preliminary results from a Norwegian research project 2005-2008 on Arion lusitanicus was presented. In private gardens handpicking had the strongest effect on the population size, but creating relatively dry and open gardens, and removing suitable overwintering sites also had effect. The geographic distribution and life cycle are also presented. Foreløpige resultater fra et norsk forskningsprosjekt 2005-2008 på Iberiaskogsnegl ble presentert. I privathager hadde håndplukk den sterkeste effekten på populasjonsstørrelsen, men også det å skape relativt tørre og åpne hager, og å fjerne gunstige overvintringssteder hadde effekt. Artens utbredelse og livssyklus i Norge ble også presentert.

Bernt-Håvard ØyenAbstract
Removal of up to 40-50 % of the total volume production by successive thinning from early age seems to have a positive effect on the yield of fresh wood in stands of Norway spruce. In young stands there is a decrease of yield caused by early, heavy thinning. The stands are usually stable and healthy. Low oriented and moderate thinning operations do not appear to influence the yield situation in general, although culmination is prolonged. Also in Central Norway difficult access to the forests, lack of roads, high labour costs and sometimes low initial densities moderate the present interest for thinning.

Science-based approaches in addressing future risks and challenges for forests require close collaboration among the communities operating different monitoring and research networks as well as experts in process and large-scale modelling. Results of the COST FP0903 conference which took place in October 2010 in Rome, reveal valuable results from different European forest monitoring and research networks. However, the need for closer integration of these activities is obvious. In this paper, representatives from major European networks recommend a new approach for forest monitoring and research in Europe, based on a reasonable number of highly instrumented “supersites” and a larger number of intensive monitoring plots linked to these. This system needs to be built on existing infrastructures but requires increased coordination, harmonisation and a joint long term platform for data exchange and modelling.
