There is an increasing awareness of how the aesthetical performance of wood exposed outdoors changes over time and especially in the first few years after installation. Mould and blue stain fungi are biological agents that contribute to the weather grey colour on a wooden façade, and the blue stain fungi Aureobasidium pullulans is commonly identified as colonizer on coated and uncoated wood exposed outdoors. In this study 21 wood substrates (untreated, preservative treated and modified) were tested for their susceptibility to A. pullulans when incubated at three different temperatures (11, 16 and 22°C). Western red cedar and preservative treated wood had the lowest mould ratings at the end of the test period (84 days). Alder, ash, Norway spruce and Sitka spruce reached maximum rating already at day 28, and at day 84 also aspen, European larch, thermally modified pine, birch, acetylated pine and DMDHEU modified pine had reached maximum rating. Incubation temperature had a significant influence on the growth of A. pullulans throughout the test period for acetylated and DMDHEU modified samples – and generally the modified wood substrates were more sensitive to changes in temperature than the other tested substrates. Scots pine sapwood seemed to be less susceptible to A. pullulans in mono cultures, demonstrating low mould ratings throughout the test period. This contradicts to previous studies were Scots pine sapwood tended to have high susceptibility when using a mix of mould and blue stain fungi.

Finding new ways to simultaneously account for monetary and non-monetary goals in ecosystem services is needed in order to establish a new modelling framework for the facilitation of trade-offs between competing stakeholder interests. The socioecological sustainability of an ecosystem service is dependent on the consent of the people in the area of the ESS. An important reason is that a given ecosystem service may have highly different value in different stakeholder cultures. In this aspect is also the understanding of disservices and hidden services. The kind and level of conflict tend to differ with location and the operational level of decision-making. It is crucial work to identify all linked subservices and organise them into a common framework for evaluation. In our research group (MULTIESS) we try to develop multi-criteria tools to assess the implications of prioritizing different interests on ecological, sociological and economic output. Similarly, changes in the human population and environment will interact and influence on the services and their values, demanding such parameters to be evaluated for the whole range of potential scenarios. We maintain that in order to make multi-criteria analyses (MCA) successful, service outputs and externalities must and can be measured in familiar terms (e.g. money, biomass) without the use of direct or stated pricing of non-commodities such as welfare, recreation or biodiversity.
