In Norway, both reindeer herders and sheep farmers base their meat production on natural outfield (utmark) pastures during the summer. In winter, most of the sheep are housed and fed indoors, while the reindeer survive on outfield pastures the whole year. During the last few decades, the losses of both sheep and reindeer to protected carnivores has increased in several areas in Norway. In this article, we focus on reindeer herding in the Troms and Nordland reindeer grazing area (reinbeiteområde). Due to large losses of reindeer calves, during the period from their birth in spring until late autumn, several reindeer herding districts hardly have any animals for slaughter. This has a very negative impact on both the economy and the cultural way of life. This article also discusses the reasons why it is difficult to document/prove who or what is responsible for the losses of reindeer calves. It is difficult to get permission to cull extra-active predators if the politically determined quota in each management region is not fulfilled. Documenting the correct number of predators inside each management region is therefore very important for reindeer herding and sheep farming. This has led to criticism and demonstrations by reindeer herders and sheep farmers. Norwegian predator policy formally builds on differentiated management. However, external review reveals that the management model builds on erroneous assumptions. Further, international law also requires that the burden created by predators does not unduly affect indigenous culture. The authors conclude that there is a need for extensive reforms in predator management in Norway.

This research aimed to determine if creeping bentgrass (Agrostis stolonifera L.) can be used as an alternative to colonial bentgrass (Agrostis capillaris L.) in a mixture with red fescue [equal rates of Chewings fescue (Festuca rubra ssp. commutata Gaud.) and slender creeping red fescue (Festuca rubra ssp. littoralis [G. Mey.] Auquier)] on Nordic golf greens managed without pesticides. The two mixtures were compared in two experiments: Experiment 1 under the creeping bentgrass management regime (mowing height, 3 mm; fertilization, 15 g N m−2 yr−1) and Experiment 2 under the red fescue management regime (5 mm and 10 g N m−2 yr−1) at three sites during 2015–2018. A seed mixture of red fescue and velvet bentgrass (Agrostis canina L.) was included in Experiment 2 only. The results showed that red fescue plus creeping bentgrass produced greens of equal turfgrass quality and with less Microdochium patch than red fescue plus colonial bentgrass under both regimes. In Experiment 2, red fescue plus velvet bentgrass resulted in higher turfgrass quality than the other mixtures but was more susceptible to Microdochium patch than red fescue plus creeping bentgrass. Tiller counts in the mixed plots at Landvik showed that red fescue was not outcompeted by bentgrass in any of the mixtures and that it was easier to manipulate the balance between red fescue and bentgrass in the mixture with creeping bentgrass than that with colonial bentgrass. More research should be put into optimal management, especially irrigation and thatch control, of mixed red fescue–bentgrass greens.
