Abstract
As part of the multipurpose forest management concept, the resource and economic potential of harvesting wild berries has been analyzed under different forest management scenarios. As a tool for forecasting and analysis, scenario-based simulation is used to model the forest ecosystems dynamics under the management of clear-cutting and selective felling. The object of research is the Pashe-Kapetskoe district forestry of Leningrad oblast; the calculation was carried out for 120 years. The potential productivity of wild berries is calculated based on the forest condition types, species composition, and simulated illumination at the ground level data. The most productive resources on the territory are bilberry and lingonberries, the predicted yield of which reaches 25–48 t/year and 7–15 t/year, respectively. Zoning of the territory was carried out according to the resources availability for industrial harvesting, taking into account the interests of the local population; 37–48% of the wild berry harvest was available for industrial harvesting, about 30% was allocated for the needs of the local population, and 27–36% of the resource remained in economically inaccessible areas. The most promising was the scenario with artificial restoration of 50% of the clear-cut areas and a full maintenance cycle. For this scenario, the maximum profitability was predicted from both the food-resource procurement (4.1–5.7 million rubles per year) and the harvesting of timber.
期刊介绍：
Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
