Productivity of Artificial Pine Stands in Ribbon Forests of the Altai Territory

Type: article
Abstract: Pure and strip pine forest plantations were widely practiced in ribbon forests of the Altai Territory by the species mixture of Scots pine (Pinus sylvestris L.) with silver willow (Salix acutifolia Willd.). In the 1990s this approach was cancelled. We can assess the productivity of those plantations so far it is still possible to determine which artificial pine forests were created with preliminary willow planting The paper presents the studies carried out in the Barnaul ribbon forest in the Rubtsovskiy and Uglovskiy districts of the Altai Territory from 2013 to 2016. Forest growth conditions are described by a sharply continental climate, lengthy cold winters and short hot summers; small (250...350 mm/year) amount of precipitation; sandy soils and the level of groundwater, located at a depth of 4 to 10 m and more. In the course of the research, the authors have used the quadrant sampling method. The sample plots (57 pcs.) are established in artificial pine forests of the forest type of dry coniferous forest of flat hilly surfaces. The investigated stands are from 13 to 81 years of age, of II-V quality class and different species mixture patterns Thinning in these stands has not been carried out. The mensurational description of the most typical studied pine forests and yield charts of artificial pine forests with different tree arrangement on the area are also presented. Data approximation is performed using the Terazaki function, since it demonstrates the highest value of the determination coefficient in comparison with the other S-shaped functions. The most productive artificial pine forests are formed from forest cultures with a uniform arrangement of seedlings in the ribbon forests of the Altai Territory. Pine stands created by the strip forest plantation method in the mixture with silver willow (Salix acutifolia) are more productive than stands formed from forest cultures with a similar arrangement of trees on the area but without willow.
