M. Asenova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This paper explores the opportunities of using Geographic Information Systems (GIS) and data from unmanned aerial vehicles (UAVs) and satellites for effective tree health mapping and assessment of forest stands, damaged from biotic and abiotic factors. The aim is to detect affected (...)


IMPACT OF ABIOTIC AND BIOTIC FACTORS ON ENGLISH OAK (QUERCUS ROBUR L.) PLANTS AFTER WINTERING IN TREE NURSERIES IN LATVIA (Papers SGEM2018)

A. Indriksons, S. Krodziniece, O. Miezite
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In Latvia, English oak Quercus robur L. planting material is grown both as bare-root seedlings and bare-root plants. Its breeding is difficult, because the quality of planting material is affected by both abiotic and biotic factors. Damage caused by various factors may be spread (...)


IMPLEMENTATION OF THE METHOD OF VARYING INTENSITY IN FOREST ECOSYSTEMS WITH A PREDOMINANCE OF LINDEN TREES (Papers SGEM2018)

V. Zakamskii, D. Egoshina
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The felling of trees on small plots, using the method of varying intensity is used in areas where widespread small-leaved Linden or she prevails.. This tree species is very closely related to beekeeping and a valuable timber.. Therefore, the proposed felling allow to organize complex (...)
