Productivity of boreal forests in insular volcanic landscape of North-Western Pacific

The empirical statistical models of the island-arc stage of continental biosphere development in the North-West Pacific have been created by the example of experimental testing area near the active Mendeleev Volcano on the Kunashir Island (the Kuril Insular Ridge). An exceptionally important backbone role of forest phytobiota in the establishment and development of young volcanic landscapes was demonstrated. The optimizing strategy program for the development of plant communities, which is aimed at the maximum biomass formation on forest island-arc landscapes, is much more marked compared to their zonal analogs on the neighboring continent. At the same time, an exceptionally high percentage of green mass in the structure of production results in the acceleration of nutrient cycle cycle as a factor of stability of forest community. All the above ensures the survival of insular ecosystems of the boreal Neo-Pacific under unfavorable conditions of «cold» oceanicity.
