Furthermore, respondents' previous experiences of the outcomes and benefits of restoration measures may explain their high willingness-to-pay in specific watersheds. The report "Ecosystems in forests - how to assess and value them" gives an overview of relevant ecosystem services in forests, providing us with timber, mushrooms, berries and wild meat, regulating services like carbon storage and sequestration, and recreation and aesthetic services (TemaNord 2014:534). These six kinds of areas can be retrieved on the map on the left with their specific number. This is an elegant way to illustrate how ecosystem services are distributed in the landscape, by this kind of management which gives a very heterogeneous exploitation. However, this report suggests that biodiversity as well as carbon uptake may be optimal in old forests.
