Global warming is already impacting the activities of many sectors of the economy. We studied this influence on forestry, particularly, temporary road infrastructure used for logging in winter. The goal of the paper is to investigate the relationship between the wood removal volumes and timing of operations temporary infrastructure in the different climate zones. We tested hypotheses for the dependence of wood removal on: a) annual allowable cut b) road density c) road density except wetlands. This paper used the data covers 1999-2009 and the territory of the Republic of Karelia. We examined two types of winter temporary road (ice roads and snow-ice roads) and two versions of their lifetime (earlier and later construction). The investigation made use of panel model with the fixed effects. Also we used one-way analysis of variance (ANOWA) to explain the territorial effects. Our main findings are that the volume depends on the type and lifetime versions of winter roads. One day winter road operation increases monthly volume of wood removal by 1485-1746 m3. We have determined the territory that is the most vulnerable to climate warming. This approach is suitable for identifying areas where should be increase road density to avoid deforestation. It can be applied to justify the state co-financing of forest road construction and to develop adaptation measures for forestry and forest industry of to climate warming.
