More is more? : Forest management allocation at different spatial scales to mitigate conflicts between ecosystem services

2017

Context: Multi-objective management can mitigate conflicts among land-use objectives. However, the effectiveness of a multi-objective solution depends on the spatial scale at which land-use is optimized. This is because the ecological variation within the planning region influences the potential for site-specific prioritization according to the different objectives. Objectives: We optimized the allocation of forest management strategies to maximize the joint production of two conflicting objectives, timber production and carbon storage, at increasing spatial scales. We examined the impacts of the extent of the planning region on the severity of the conflict, the potential for its mitigation…

Managing boreal forests for the simultaneous production of collectable goods and timber revenues

2016

Timber Production is an economically important provisioning ecosystem service in forests, but is often in conflict with the provision of other ecosystem services. In multifunctional forestry, the production of timber and non-timber ecosystem services should coexist in the same landscape. To this end, we explored the capacity of a boreal landscape to simultaneously produce collectable goods − bilberry (Vaccimium myrtillus L.), cowberry (Vaccinium vitis-idaea L.) and cep (Boletus edulis Bull.) − alongside timber revenues. We also identified optimal forest management plans to achieve this. Furthermore, we analyzed trade-offs between collectable good yields and timber production, as well as bet…

High rates of short-term dynamics of forest ecosystem services

2021

Currently, the main tools for assessing and managing ecosystem services at large scales are maps providing snapshots of their potential supply. However, many ecosystems change over short timescales; thus, such maps soon become inaccurate. Here we show high rates of short-term dynamics of three key forest ecosystem services: wood production, bilberry production and topsoil carbon storage. Almost 85% of the coldspots and 65% of the hotspots for these services had changed into a different state over a ten-year period. Wood production showed higher rates of short-term dynamics than bilberry production and carbon storage. The high rates of dynamics mean that static snapshot ecosystem service map…

Trade-offs among intensive forestry, ecosystem services and biodiversity in boreal forests

2018

Finnish forests are used extensively for timber production but are also providers of other ecosystem services and harbor unique biodiversity. The ecosystem services approach has so far been used marginally in the context of Finnish forestry; however, due to the multiple values associated with Finnish forests and the impacts forestry operations have on forest ecosystems, it is clearly applicable in this context. In this thesis, I studied the occurrence and severity of trade-offs among ecosystem services and biodiversity conservation in Finnish forests. I used forest inventory data, forest growth simulations, and multi-objective optimization to reveal how the severity of the trade-offs varies…

Metsien käytön kestävyysmuutoksen mittaamisen periaatteista

2022

Suomalaisen metsäpolitiikan keskeinen päämäärä on jo yli sadan vuoden ajan ollut puuntuotannollinen kestävyys, mutta metsätalouden kestävyyden tarkastelu on laajentunut yhteiskunnallisten tarpeiden ja arvostusten muuttumisen myötä. Nykyisin metsäpolitiikan tavoitteeksi mainitaan usein kokonaiskestävyys, joka on kuitenkin kestävyyden osa-alueiden välisten subjektiivisten, kullekin arvioijalle yksilöllisten vaihtosuhteiden takia mahdotonta saavuttaa. Tässä tutkimuksessa määrittelimme tutkijatyönä laatuvaatimukset kestävyyskeskustelussa käytettäville kriteereille. Tarvitaan kattava ja operatiivinen kriteeristö, jolla kestävyysmuutoksia voidaan objektiivisesti seurata. Kattavuus tarkoittaa, ett…
