The Arkhangelsk region is one of the leading forest industry centers of Russia. The region possesses significant chemical and mechanical wood processing facilities, producing about one third of the pulp and cardboard, also up to 10% of sawn timber, paper and fuel pellets of the total volumes in Russia. One of the forest industry?s problems is a historic underdevelopment of an infrastructure, in particular ? lack of transport links. Due to low population rate, the density of the land transportation system is minor,...

Large reserves of forest resources (according to UN estimates, the area of forests in the Russian Federation, is 8.5 million km?) have provided a significant development of the forest industry. Together with large investments in the timber industry complex, it became possible to optimize the technological processes, machines and equipment of enterprises. At the same time, it is also necessary to solve the issues of the most rational forest management. Sustainable forest management assumes limiting of the volume of...

The paper presents observations of solution of the sustainable forestry problem in terms of the Arkhangelsk region. One of the sustainable forestry guidelines is appropriate restraining of the forest harvesting. The volumes of logging in the Arkhangelsk region constitute about half of the allowable wood removal. One of the reasons of the harvesting volumes insufficiency is low density of forest roads network, therefore the accessible areas alongside the existing roads are depleted. The forest roads network should ...
