Lodgepole pine of Yukon origin in the European North of Russia

The article is devoted to the study of Lodgepole pine plantations of northern Canadian (Yukon) origin, created in 1988 in the Arkhangelsk region on three sites with different growing conditions using different methods of the soil preparation for planting. The main research objective was studying the growth, sustainability and productivity of Lodgepole pine of Yukon origin in the conditions of introduction. The objects of research were three experimental plots of Lodgepole pine, created in 1988 in the Arkhangelsk region with two-year-old seedlings from seeds of Yukon origin. The results of Lodgepole pine growth in height, diameter and trunk volume indicate that this pine responds well to improved soil cultivation conditions and, undoubtedly, to pre-plant soil preparation. Lodgepole pine is characterized by good growth and straightness in the myrtillosum forest type and special microclimatic conditions on the Solovetsky Islands. Resulting from the study of growth and development of Lodgepole pine of Yukon origin, it was concluded that the creation of fast-growing forest plantations of this species is recommended in productive forest types of the hylocomiosa group (oxalidosum and fresh myrtillosum).
