In this papercomparative analysis ofthe two methodsof reforestation is done: by furrowsandby biogroups. Experimental data confirm the influence of the methodof reforestationon the structure offorest phytocoenosesof artificial origin. The article deals with artificial forest phytocoenoses created in two waysin the Tambovregion, wherehistoricallypineforests dominate andthere is the problemof theirdisplacementby lessvaluable species, such as aspen.The aim ofthe studyis to examine thewaysof reforestationby biogroups and comparing it with there forestation by furrows. As a result ofthe fieldthe period 2011-2013measuringof treesof biogroups is made, basicbiometrical parameters are obtained. Statistical data processingis made.Biometricsof biogroups is considered separately for the trees of the central andouterrows. Based onthe visualassessmentof tree conditionof biogroups and consistent with theirbiometricsdivisionof viabletreesseparatelyfor the central andouterrowswas madeinto classes according togrowthrate.
