Natural regeneration after partial logging in pine forests of Krasnoyarsk forest steppe
The results of the study of the quantity and state of understory of young’s regeneration after partial logging of 20 to 53 % logging intensity in mature pine forests of Pogorel’skiy pine forest are shown. Evaluation of logging operations showed that under the canopy of the remaining part of tree sta...

The results of the study of the quantity and state of understory of young’s regeneration after partial logging of 20 to 53 % logging intensity in mature pine forests of Pogorel’skiy pine forest are shown.
