The tree growth compensation followed by insect damage is important for tree survival. Insect damage by making 3 and 6 holes per each leaf, and clipping one third of a leaf were simulated for one-year old silver birch (Betula pendula Roth) seedlings once, at the beginning of the vegetation season. The height, aboveground and root biomass, root length, stem diameter and leaf area were measured for all damaged and control seedlings. The aim of the study was to examine the effects of different insect-damage simulations on silver birch growth. Our study demonstrated that leaf dry mass decreased in response to leaf perforations and clipping one third of leaf. However, at the end of the experiment, the cumulative dry mass reached the level of the control. We found no statistically significant effect on the aboveground and total biomass of damaged seedlings compared to the control. The leaf clipping decreased the leaf area and stem diameter compared both to the treatment with hole-damaged seedlings and the control. The induced birch growth response showed that tree seedlings were able to compensate their growth up to the control level after the insect damage in eight weeks.

Wind is an important natural disturbance factor in a forest ecosystem. It creates gaps in a forest canopy, providing microenvironmental conditions, suitable for forest regeneration and affects the species composition of ground vegetation. Most of the studies analysing consequences of wind-storm have addressed short-term changes or influence the stand structure, but the aim of our study is to analyse ground-vegetation long time after windstorm in hemiboral forests. Data on ground vegetation cover have been collected in areas affected by the storm of 1967, where due to salvage-logging 200-400 m wide clearcuts were created. Sample plots (1×1 m) were placed in different distance from the edge of former clearcuts and projective cover of ground vegetation assessed using Braun-Blanquet method in Myrtillosa mel. forest type on 5 sites in north-western part of Latvia. Results reveal that in all sites species belonging to boreal, boreal-temperate and temperate biome were present, but their proportions varied between sites. In total 82 species of vascular plants were found, most frequent among them Maianthemum bifolium (L.) F.W.Schmidt (species characteristic to Norway spruce forests), Vaccinium myrtillus L. and Vaccinium vitis-idaea L. (associated with Scots pine forests) as well as Molinia caerulea (L.) Moench and Deschampsia caespitosa (L.) P.Beauv. (both characteristic to wet soils). Results suggest, that even 47 years after the storm microenvironmental conditions in the sites are not stable. Ellenberg’s indicator values reveal, that most of the sites are in semi-shade, cool and moist conditions, placed on acidic, nitrogen-poor (in few sites – also nitrogen rich) soils.

Thinning of young forest stands is a contribution to the future of the stand development. Our study focuses on damage of the remaining trees and soil. Now it is common to see thinning of young stands with heavy forest machines, but most of these operations take place in commercial thinning. This study is focused on precommercial thinning to evaluate different mechanized thinning methods in relation to the damage done to the remaining trees and soil in deciduous tree stands. Data were collected in four stands where the average diameter of trees at breast height was 6.2 cm, the height of average trees - 9.5 m, but number of trees per hectare was more than 2900. The stands regenerate naturally. Damage was evaluated separately after harvester and forwarder operations. The study proves that forwarding makes much less damage to the remaining trees than harvesting. According to the study data, the traditional method results in the largest number of damaged trees, because operators need to cut all trees closer than 1.5 m from the target tree. Both schematic thinning methods result in significantly less damage. A statistically significant difference (p is less than 0.001) was found in a proportion of damaged remaining trees between all of the applied working methods. The smallest amount of damage is associated with complex symmetrical thinning method. The most damage appears during harvesting. The aim of this study was to compare three working methods of biofuel production in pre-commercial thinning using harvester John Deere 1070D with accumulating felling head Bracke C16.b in grey alder (Alnus incana) pure stand.

Land use change has caught scientist’s attention all over the world and in the perspective of globalisation the pressures on agricultural land are increasing. However, the agricultural land abandonment is still evident. This phenomenon has no single definition and its driving forces are varying among different regions and countries. In this paper agricultural land is considered as abandoned while there is evidence of shrub and bushes on agricultural land according to the orthophoto and Estonian base map comparison. The aim of this paper was to test the impact of arable land plot spatial properties: plot area, ratio of arable land area in the surrounding of plot and plot compactness. General hypothesis is that brushwood will more likely occur on the arable land plots with poor spatial properties than on arable land plots with good ones. The study was conducted in 15 rural municipalities across Estonia. Results are showing some impact of the spatial properties on the arable land plots conversion into brushwood. In nine municipalities out of 15, there was an arable plot area without brushwood larger than plots with brushwood and the percentage of arable land area surrounding plots without brushwood was higher in other 9 studied municipalities. As expected, the uncompact arable land plots tend to have more likely brushwood on them than the compact ones. Study results show that the impact of plot area and the ratio of arable land in surroundings of plots on the conversion of arable land plots into brushwood need further studies.

The article addresses the problem of social dimension measurement of for regional development. Authors’ discus approaches of definition of social dimension. There is some discord how social dimension could be understood in more broader or narrowed sense and how it is characterized in international and national social policy documents. Authors focus attention on contiguity of social dimension and social security. The measurement of social dimension demands multidimensional approach. The authors use theoretical analysis and document analysis, as well as analysis of statistical data on key elements of social dimension of regional development (differences of employment rate; GINI coefficient, and the number of people at risk-of-poverty threshold). The main conclusions are that social dimension is more or less covered in development planning documents, but the progress indicators are inadequate. Especially disparities in social dimension of regional development are formally addressed and closer analysis of key indicators shows necessity to elaborate both – policy instruments as well as policy progress measurement.

The objective of the paper research is to assess the role of the implementation of the local development strategies (LDS) elaborated by the local action groups (LAGs) in the regional development and addressing social problems in Latvia. The paper examines the role and place of LDS in territorial development planning in Latvia, carries out thematic analysis of the projects implemented under the LDS as well as tries to assess the LEADER approach impact on regional development and addressing of social issues on the local level. The authors use unpublished data on LEADER projects and apply quantitative and qualitative analysis methods. Most of LEADER projects have been implemented to facilitate the development of infrastructure related to recreation and quality leisure time as well as culture and sports. Rural inhabitants have noticed positive changes in their local territory introduced by the LEADER approach. Though, in order to enhance the role of LAGs and LDS in addressing regional development and social problems at local level, it is advisable that the potential interaction of the activities provided by all regional planning documents is observed when determining priorities at regional level (presently the place and role of the LDS has not been formally defined), while implementation of the LDS should pay more attention to long-term effects and even accomplishment of target priorities.

Currently one of the hottest local governments’ issues on the agenda of the government of Latvia is the elaboration of new improved local government finance equalization system, which is an important integral element of the implementation of regional development policy. Local government finance equalization is affecting development capacity of any territory, including rural territories. The purpose of the article is to highlight and discuss in academic society the finance equalization issues that affect the rural municipalities and work out proposals for the new system. The study does not cover all local government finance equalization system’s elements, but gives attention to three – importance of the equalization for rural local governments – municipalities (novads); revenue sources, that are necessary to include in the equalization system; criteria for calculation of local governments’ expenditure needs.

One of the most challenging issues of EU agriculture is viability of farmers’ and family farms. These farms used to play a major role in new member states. However, the last decades are characterized by the significant decrease in the number of farmers’ farms. The paper deals with the issues of these farms’ viability and the role of support. A literature review on viability concept and indicators justify the selection of socio-economic viability criteria for the survey. The findings are based on the results of Lithuanian farmers’ opinion survey. The analysis of the selected socio-economic criteria of viability shows that crop production farms are characterized as the most viable. According to the survey results, the farms with less than 30 ha, and the farms operated by farmers aged 60 and older belong to the most vulnerable group. These farms are non-viable in the long-run. The risk estimation of staying in agricultural business if support is abolished for viable and non-viable farms shows dependence of farm’s behaviour and viability status.

In the current context of economic instability, youths are faced with the emergence of a feeling of uncertainty with respect to their own chances of having a good debut on the labour market. The world crisis, the social reality that all societies are faced with, brought again up to the forefront the idea of young individuals’ fragility on the labour market (Balan, 2014). According to Eurostat statistical data, in the European Union young people represent one-fifth of the total population. Today the young people are facing the impacts of economical crisis and globalisation, population ageing and innovation explosion, which affects employability, education and training systems and social development. Successful youth’s integration into the labour market is one of the main factors for future development and their inclusion into society. One of the main indicators for youth’s inclusion into society is the development of a knowledge-based economy. It is important to aim at the development of a knowledge-based economy in rural regions because the majority of unemployed persons are concentrated in these regions. The Quintuple Helix Model represents the relationships between universities, firms and governments and, in this case, their influence on youth’s integration into the society and labour market in rural regions. The paper presents a brief analysis of youths’ unemployment development and their integration into the labour market in Latvia’s regions and an analysis of the factors affecting this phenomenon by using the Quintuple Helix Model.

rural tourism homestead choice in Lithuania. The aim of the research was to determine the balance between the importance and performance of factors affecting the choice of rural tourism homestead in Lithuania. The questionnaire research was provided in Lithuania in 2014. Tourists’ evaluations regarding five exogenous latent variables: ‘accommodation and catering’, ‘activities in destination’, ‘natural features’, ‘destination aesthetics’, and ‘environmental preservation’, and four endogenous latent variables: ‘destination marketing’, ‘perceived value’, ‘satisfaction’, and ‘loyalty’ were measured. The total effects for the specific endogenous constructs in the structural model (importance) and the average values of the latent variable scores, rescaled to a range of zero and 100 (performance) were measured to compose the importance performance grid. The research results indicate that the most important factors for tourists while choosing a rural tourism homestead in Lithuania are ‘destination marketing’, ‘environmental preservation’, ‘perceived value’ and ‘satisfaction’. Moreover, the highest share of the total investments allocated to satisfy tourists and enhance the level of loyalty should be accrued to the improvement of ‘destination marketing’ and ‘environmental preservation’.
