The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock …
… fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also …

… a thinning machine team. The purpose was to investigate in which machine, the harvester or the forwarder, that caused most damage to the trees in six different stands. Different factors, related to the damage frequency in the stands, were checked out. For example: basal area per …
… The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate …

Detta arbete behandlar mätteknik vid kontroll av dubbskadedjup på sågtimmer. Mätmetoder och mätverktyg har sammanställts och bedömts som lämpliga för olika mätsyften. Data rörande skadedjup från olika dubbtyper har sammanställts ifrån tidigare publicerade studier. Resultat från …
Projektet Curiosity > Harvest handlar om självhushållning som en del i det moderna livet i staden, och mer specifikt biodling i den urbana miljön. Dels ur perspektivet att knyta samman stadsmänniskan med matproduktionen och förutsättningarna för livet, och dels ur perspektivet …
… and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage. In this paper, two trials with three drainage distances, performed at Lanna experimental …
Sustainable water supply solutions for areas affected by water shortage
… options were investigated: artificial groundwater recharge, rainwater harvesting, desalination and water reuse. The second part of the work consisted of developing a method for choosing the best water supply solution based on nature-given and social conditions. The method …
… seed production, which is not possible when selling to the grain trader at harvest (Pers. Comm., Gillsjö, 2015). A farm-based grain handling facility means streamlining the farm operations and gives the opportunity to achieve higher profitability. The aim of this study is to …
… demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason …

… upon because the moose population believed to be too small for a sustainable harvest. The break lasted for four consecutive hunting seasons. Before the on set of the hunt in the fall of 2006, two moose management areas had been established; one for Borgholm and one for …
… the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study …
… among other things, maps. The other one was a production file from a harvester that only contained about 7kb. The time for sending these files was at most times about 2.30 min-utes except when the transmission took place in the outer parts of the service area where there was a …
