Denne rapporten presenterer resultatene fra en taksering av naturlig foryngelse i 99 bestand på bonitet G14 i Romedal og Stange allmenninger. Arealene ble markberedt i perioden 2001–2006, og var avvirket ved flatehogst der målet var naturlig foryngelse av gran basert på frø fra bestandskant. Takseringen ble gjennomført i juni – oktober 2008. Arealene fordelte seg med 29 bestand i bærlyngskog, 52 bestand i blåbærskog, og 18 bestand i småbregneskog. Granplanter som hadde spirt våren 2007 (toårig gran) utgjorde det største bidraget til foryngelsen i de fleste bestandene....

Antallet aktive bruk i Nord-Norge synker, men størstedelen av jorda holdes i hevd ved at drifta overtas av andre bruk. Men hvilke faktorer er det som avgjør om et areal drives videre eller går helt ut av produksjon?

In 2008, severe outbreaks of Neonectria canker were found on white fir (Abies concolor) in southern Norway, and a Neonectria sp. was isolated from two counties in southwestern Norway and four counties in southeastern Norway. Both old and young trees were dead or dying. The same Neonectria sp. was also isolated from Siberian fir (A. sibirica), subalpine fir (A. lasiocarpa), and Norway spruce (Picea abies) in southeastern Norway. Previously N. fuckeliana had been reported on spruce species in Norway and on spruce and fir species in other countries. Sequencing of the internal transcribed regions (ITS) of ribosomal DNA showed that all of the isolates from 2008 were identical and were more similar to N. ditissima (syn. N. galligena) than to N. fuckeliana. The isolates were five base pairs different from N. ditissima, and they may in the future be considered a new species. The perithecia were dark around the ostiole. This morphological characteristic is known from N. ditissima, but not from N. fuckeliana. Inoculation tests were carried out on subalpine fir, white fir, and Norway spruce, and the fungus was pathogenic on all inoculated species. Thiophanate-methyl proved very effective against Neonectria sp. in laboratory fungicide trials.

Two Malaise traps were set up at Ås, Southern Norway, during the growing seasons 1992-1997, one trap in an organic grown barley field and one in its boundary. Totally 23 species of Tipulidae (Diptera) were identified, of these eight species belonged to the genus Nephrotoma Meigen, 1803. Of the total specimens collected 93% of the males and 88% of the females belonged to this genus. Comparing the two traps, 80% of the Nephrotoma specimens were recorded in the organic field. It is discussed if larvae of Nephrotoma spp. in Norway can be potential pests in agricultural crops as reported from other countries. To Malaisefeller ble plassert ut i Ås i vekstsesongene 1992-1997, en i en økologisk dyrket byggåker og en i kanten av åkeren. Totalt ble 23 arter av stankelbein (Tipulidae, Diptera) identifisert, 8 av disse tilhørte slekten Nephrotoma. Av det totale antall individer som ble samlet inn, var 93 % av hannene og 88 % av hunnene av slekten Nephrotoma. 80 % av Nephrotoma-individene ble funnet i den fellen som sto ute i byggåkeren. I mange andre land er larver av Nephrotoma-arter skadedyr på mange kulturplanter i jordbruket, og det diskuteres om disse artene kan opptre som skadedyr i Norge.

The NETALGAE project aims to create a European network of relevant stakeholders within the marine macroalgae sector, by creation of business tools such as database, website, trade directory and training materials. The project runs from 2010-2012, and is financed by the Atlantic Area Transnational Programme, The European Regional Development Fund and by national co- funding.

The project aims to create a European network of relevant stakeholders within the marine macroalgae sector, by creation of business tools such as database, website, trade directory and training materials. The network will include primary producers, processors, technology suppliers, process consultants, research institutes, development agencies, local governments and relevant community groups and other stakeholders. A wide ranging policy study will establish a best practice model and suggest policies for the successful and sustainable commercial utilization of marine macroalgae resources. The project runs from 2010-2012, and is financed by the Atlantic Area Transnational Programme, The European Regional Development Fund and by national co- funding. The project is lead by Indigo Rock Marine Research Ltd., Ireland. Partners are Bord Iascaigh Mhara (Ireland), Syndicat Mixte Pour l´Équipement du Littoral, Fisheries and aquatic sciences center- AGROCAMPUS OUEST and Université de Bretagne Occidentale (France), BIOFORSK (Norway), Universidade do Algarve (Portugal), Mutrikuko Institutua, Ikaslan Gipuzkoa and TKNIKA (Spain) and Viking Fish Farms, Ardtoe Marine Laboratory, UK. This poster will present the NETALGAE project, its aims, objectives, partners and preliminary results.
