Stamräkning och identifiering av åtgärdsbehov i röjnings- och gallringbestånd med hjälp av låghöjdsbilder
This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.
Stormskador i lärk och gran : en jämförelse efter stormen Gudrun
The storm Gudrun January 8-9 2005 felled about 70 millions cubic metres forest in southern Sweden. The majority of the wind damaged forest was spruce (Picea abies). In order to decrease the risk of wind damages in the future other trees species are of interest for forestry in southern Sweden.
The purpose of this master thesis was to study if larch were more wind tolerant than spruce. The method was to compare larch, Japanese larch (Larix kaempferi Lamb.), European larch (L.
Underröjning i förstagallring :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers,
SLU. The work was an assignment from Sydved and the aim of the work was to investigate the economical output of removing understorey trees before first thinning.
Four treatments were studied.
- no cleaning before thinning
- cleaning of all trees less than DBH 5 cm before thinning
- cleaning of all trees less than DBH 7 cm before thinning
- cleaning of all trees less then DBH 9 cm before thinning
The result shows a decrease of the cost per m3 for the harvester with about 38% if all trees less than DBH 9 cm was cleaned before thinning compared with the un-cleaned area. At the same time the total net revenue increases with about 22%.

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.
Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.
Nespresso - Ett koncept att sträva efter
Background: Nespresso is a part of the Nestlé group and was founded in 1986, in the liaison of the revolutionary new method of brewing coffee. The idea was that everyone should be able to brew themselves a cup of espresso that would taste as if a professional barista had done it. Nespresso has now turned in to a new coffee culture. From the beginning Nespresso only sold their products via their club, Nespresso Club, but in year 2000 they opened their first store in Paris. The first store in Sweden opened year 2006 in Stockholm, followed by one in Malmö year 2012.

Utomhuspedagogik i skogen för barn : skötsel och informationsförslag för Stadsliden, en stadsskog i Umeå
Vistelse i naturen har visat sig vara bra för både den fysiska och psykiska hälsan hos barn. Utomhuspedagogisk verksamhet i förskola och skola är mycket viktigt för att barn ska komma ut i naturen idag. Den tätortsnära skogen är en viktig arena för utomhuspedagogik och de utomhuspedagogiska värdena där kan säkerställas med en skötselplan.
Studieområdet Stadsliden är en central och välbesökt stadsskog i Umeå. Skötselplanen för Stadsliden ska nu förnyas och en av de nya målsättningarna för skogen är att den ska erbjuda pedagogiska miljöer för förskola och skola. Kvalitativa respondentintervjuer med lokala pedagoger jämte inventering av studieområdet utfördes för att dokumentera utomhuspedagogiska värden i Stadsliden, i form av skogliga värden samt informationsmaterial.
Studiens resultat visar att pedagogerna främst värdesatte närhet till skogen.

PAPRO operates within the Forest Research company and their mission is to develop value-addingindustry solutions. At present there are no good ways for mills to easily test the printing quality on newsprintpaper. There is a great need for a fast way to do this on different paper qualities; with a laboratory-offset press this can be both a time and money saving method. At PAPRO Forest Research, NewZealand, a laboratory offset press has been developed and designed, during the past seven years, concerningthis issue. Earlier projects were made concerning the press, e.g.
Kryogen uppgradering av biogas med kyla från värmedriven absorptionskylmaskin
Detta är ett examensarbete som genomförts hos Göteborg Energi AB och syftar till att utreda omkryogen uppgradering av biogas med fördel kan ske genom att producera nödvändig kyla medvärmedriven absorptionskylmaskin. Göteborg Energi är en av tre parter som tillsammans ska bygga enbiogasanläggning i Lidköping som ska vara i drift 2010. Anläggningen ska producera 30 GWhflytande biogas per år.Arbetet utreder om det är fördelaktigt ur ekonomiskt, energimässigt och miljömässigt perspektiv attuppgradera biogas med kryogen teknik med värmeproducerad kyla. En jämförelse görs först medkryogen teknik där kylan är producerad med el och sen med andra uppgraderingstekniker. Som stödhar två olika processimuleringsprogram används, Hysys och DESIGN II.Resultatet visar att energianvändningen ökar då värmedriven kyla används i jämförelse med kylaproducerad med el.
Erfarenheter av uppföljning efter gallring och föryngringsavverkning för att nå kraven i miljöcertifieringssystemen FSC och PEFC
Miljöcertifieringssystemen PEFC och FSC ställer krav på uppföljning och revision för att säkerställa att kraven och kvalitén uppnås. Studiens syfte var att belysa de skogliga maskinentreprenörerna och förvaltarnas/virkesinköparnas erfarenheter av arbete med uppföljning inom miljöcertifierat skogsbruk. Materialet insamlades genom telefonintervjuer och analyserades med kvalitativ innehållsanalys, vilket ledde fram till resultatet. Uppföljningen och traktdirektivet har en viktig roll för att nå miljöcertifieringarnas krav. Dialog och delaktighet mellan de olika yrkesgrupperna var viktig, enligt respondenterna, för att miljöcertifieringen ska nå en hög kvalité och för att skapa engagemang och vilja att förbättra arbetet..
