DOES THE POLLUTION WITH HEAVY METALS FROM BRAȘOV, ROMANIA INFLUENCE THE FOREST ECOSYSTEMS FROM PIATRA CRAIULUI NATIONAL PARK IN THE CONTEXT OF CLIMATE CHANGE? (Papers SGEM2018)

D. Vasile, M. Dinca, R. Enescu, E. Vechiu, V. Crisan
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT A major factor which affects the structure, function, and dynamics of forest ecosystems can be beyond climate, the use of the land, respectively land-cover change and pollution loading. The forest ecosystems can be affected by pollution, by alteration of biotic and abiotic properties (...)


ENERGY WOOD RESOURCES EVALUATION IN LATVIAN FORESTS (Papers SGEM2018)

A. Indriksons, M. Graudums, E. Erzama, I. Uerte, E. Baiks
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Considerable efforts have been devoted to the exploration of Latvian forest resources as the most significant national natural wealth. The State Forestry Research Institute is conducting the statistical forest inventory, is fixing the data of felling and recovery of forest stands. (...)


A LOCAL AREA TREE SPECIES CLASSIFICATION (Papers SGEM2018)

A. Bücken, J. Roßmann
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Many automated processes in the forestry sector require a tree species classification to locate individual trees or to distribute data to several species. There is already a huge number of classification approaches, which can be found in the literature. But still there is no global (...)


BLUE INTENSITY IN LARIX SIBIRICA TREE RINGS AS A NEW PALAEOCLIMATE PROXY IN ALTAI, RUSSIA (Papers SGEM2018)

D. Ovchinnikov, A. Eremina, S. Ovchinnikov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Dendroclimatic studies based on the use of various indicators of annual tree-ring structure (width, maximum density, cell wall thickness, lumen size etc.) have become widespread over the past decade. However, reconstructions of climatic characteristics revealed limitations associated (...)
