Decay in external wooden structures has historically been a universal problem of great concern. Despite this, the general understanding of where and why wood-decaying fungi are occurring is limited. The consequences of this are that decayed wood might not be detected and that measures to protect the wood against deterioration has limited effect. Wood decay in different geographical and climatic areas can be caused by different wood-degrading fungi. However, our studies show that the damage pattern is to a large extent similar, regardless of whether it occurs in temperate areas or alpine and polar regions. On high Arctic Svalbard and Alpine Finse, there are many wooden structures that are exposed to the weather and in contact with the ground. The wood in these structures has both a technical function and historical value. It is therefore important that fungal decay leads to technical failure, loss of historical value and large repair costs are avoided to the greatest extent possible. This requires a good knowledge of where and why rot damage occurs, both in general and in relation to ongoing climate change. Our experience is that many professional communities lack an understanding of the issues and methods for investigating and understanding rot damage. The deficiency in knowledge and awareness complicates the selection of the optimal repair method and, in the worst-case scenario, may exacerbate the progression of the damage.
