Forests provide a wealth of benefits to human society including provisioning, regulating and cultural ecosystem services. The majority of studies that manipulated forest diversity have thus far focussed on ecosystem processes/functioning rather than services.
This project will explore effects of tree species diversity on ecosystem services in a long-term Satakunta forest diversity experiment established in SW Finland in 1999 (www.sataforestdiversity.org). The experiment consists of monocultures and different 2-, 3- and 5-species mixtures of conifers and broadleaves.
The project will focus on some of the following forest ecosystem services and potential trade-offs between them:
– Pest control (herbivore damage and natural enemy effectiveness in mixed and pure stands)
– Nutrition provisioning (e.g. production of wild edible berries in mixed and pure stands)
– Wood provisioning (comparisons of timber production in mixed and pure stands)
– Cultural services (e.g. aesthetic value provided by mixed and pure stands)
This project offers the prospective student a unique experience of field work in a longterm large-scale forest experiment as well as training in use of various sampling techniques, experimental design, and data analysis.
