Transitions in herd management of semi-domesticated reindeer in northern Finland. 45
2008
In northern Finland, reindeer-herd management has experienced two major transitions: extensification of intensive herding, and development of supplementary/corral feeding in winter. The transistions were studied in six herding associations in different parts of the Finnish reindeer management area. It was suggested that intensive herding turns into more extensive forms as the reasons for intensive herding (predation, reindeer disappearing to foreign areas, protection of agricultural fields) gradually ceased to exist. The results of the study, based on interviews of elderly reindeer herders, were variable. In the three southern areas intensive herding changed to the free ranging system at th…

Improving Economic Management Decisions in Forestry with the SorSim Assortment Model
2020
The sustainable supply of timber is one of the most important forest ecosystem services and a decisive factor determining the long-term profitability of forest enterprises. If timber production is to be economically viable, there must always be a way to analyse forest stands and trees felled for exploitation with regard to the wood assortments they contain. Only then can the expected timber yields, achieved by various silvicultural strategies or actions and different sorting options, be quantified with sufficient accuracy. The SorSim assortment simulator was developed for forest practitioners and forest scientists in Switzerland to realistically simulate the sorting of individual trees and …

Optimizing management to enhance multifunctionality in a boreal forest landscape
2017
The boreal biome, representing approximately one-third of remaining global forests, provides a number of crucial ecosystem services. A particular challenge in forest ecosystems is to reconcile demand for an increased timber production with provisioning of other ecosystem services and biodiversity. However, there is still little knowledge about how forest management could help solve this challenge. Hence, studies that investigate how to manage forests to reduce trade-offs between ecosystem services and biodiversity are urgently needed to help forest owners and policy makers take informed decisions. We applied seven alternative forest management regimes using a forest growth simulator in a la…

Metsien hiilensidonta on keskeinen kysymys ekologisessa siirtymässä, ja metsäekologioiden ja biodiversiteetin tilaa olisi kohennettava kiireisesti. Toisaalla metsäresurssien odotetaan toimivan materiaalisena pohjana uudelle vihreän kasvun biotaloussyklille. Samalla metsäteollisuuden kannattavuus on laskussa ja sen materiaalinen läpivirtaama on kasvanut. Tähän tilanteeseen johtaneita kehityskulkuja selitetään tässä artikkelissa kuitupuukapitalismiksi kutsumamme metsätalouden tendenssin avulla. Tarkastelemme kuitupuukapitalismia James C. Scottin luettavuuden (legibility) käsitteen sekä voiton suhdeluvun laskutendenssin teorian kautta. Esitämme historiallisen tarkastelun pohjalta, että kuritto…
Management diversification increases habitat availability for multiple biodiversity indicator species in production forests
2022
Context Forest biodiversity is closely linked to habitat heterogeneity, while forestry actions often cause habitat homogenization. Alternative approaches to even-aged management were developed to restore habitat heterogeneity at the stand level, but how their application could promote habitat diversity at landscape scale remains uncertain. Objectives We tested the potential benefit of diversifying management regimes to increase landscape-level heterogeneity. We hypothesize that different styles of forest management would create a diverse mosaic of forest habitats that would in turn benefit species with various habitat requirements. Methods Forest stands were simulated under business-as-usua…
