Book (series)Country profile – Lithuania
AQUASTAT Report
2016Also available in:
No results found.This country profile describes the state of the water resources and water use, as well as the state of agricultural water management in Lithuania. The aim of this report is to describe the particularities of the country and the problems met in the development of the water resources, and irrigation in particular. Irrigation trends, existing policies and legislation to water use in agriculture, possible treaties and agreements between countries as well as prospects for water management in agriculture are presented, as described in literature. The AQUASTAT country profiles are based on the information available at the time they have been written or updated, generally every five to ten years. For the most recent reliable country data, reference is made to the AQUASTAT main database. -
DocumentModelling pine and spruce wood mechanical properties in different initial stand density plantations in Lithuania
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Two main parameters of wood quality in constructions are wood modulus of elasticity (MOE) and bending strength (MOR). To understand what kind of quality wood we are growing in our forests and how environment and forest management could affect wood quality parameters, we need to model these parameters by stand, tree, and sample results. This would help to predict MOE and MOR for the future stands.
To determine the influence of stand density and thinning intensity on wood mechanical and physical properties of Scots pine and Norway spruce, the data was obtained from experimental trials plots, which were established in 1990 by Institute of Forestry. The experimental object was divided to a smaller trial plots with different initial stand density: 2 plots with 3000-4400 trees per hectare, 2 plots with 2000-2400 trees per hectare, 2 plots with 1000-1200 trees per hectare. In these trial plots different thinning programs were used 3; 2; 1 time. From each trial plot 6 model trees were chosen (38 Spruce and 76 Pine trees).
Models were created by SAS statistical package. General linear regression models were chosen to create 4 models for prediction of: dynamic modulus of elasticity for log (MOElog); dynamic modulus of elasticity for samples (MOEdyn); global static modulus of elasticity (MOE) and bending strength (MOR) All parameters for creating models were chosen as random effects. Stand parameter was stand density (SD). Tree parameters were diameter at breast high (DBH), competition index (CI), average ring width (RD), average ring density (RD) and log high (LH). Sample parameters were knot at fracture point (K) and sample wood density (WD).
Best result for MOE models was in pine stand R2=0,82 spruce stand R2=0,85. R2=0,57 was in pine stand for MOR and R2=0,65 in spruce stand. Keywords: Sustainable forest management, Research ID: 3484790 -
Book (series)Completing the Transition: Lithuania Nears the End of its Land Restitution and Reform Programme 2000
Also available in:
No results found.Land reform has been a strong part of the overall re-structuring of the Lithuanian economy and it has contributed to the gains in living standard that have been achieved since 1994. Like the other former Soviet states, Lithuania suffered strong declines in agricultural and industrial production following independence.
