The aim of this paper is to analyze the structure of forest landscape and its impact on biodiversity in the Bauska District, Latvia. The database of the State Forest Service and field research from 1994 to 2004 were used. Diversity and protection of the current forest ecosystems were described using different forest classification methods. The structure of tree species and their age was analyzed. Analysis indicated a decrease of oak forests by 3.5% of their native vegetation area and a high proportion of drained forests, as well as a disproportional age structure of forest ecosystems.

In Greece, there is no official inventory for the activity land use, land use change and forestry. The national forest inventory was completed in 1992. Using the data of this inventory, the carbon store of woody biomass of Greece has been estimated by FAO-TBFRA (2000) as 52.04 millions t C, of which 46.36 millions t C is above stump biomass and 8.67 millions t C is stump and root biomass.

It is important to reclam degraded soils in forest nurseries to get quality planting material. Organic wastes and fertilizers on their base may be used for it. The aim of the research is to evaluate the effectiveness of influence of non-traditional fertilizers on the basis of organic waste on fertility of sod-podzolic soils, growth of seedlings and saplings of trees in forest nurseries. In the course of the research such problems as influence of non-conventional fertilizers on properties of sod-podzolic soils were studied.

Fossil pollen and plant macrofossils over the last 2000 years are documented from three small forest hollows in Southern Sweden. One of the sites is inside a 5 ha highly prized old growth mixed Fagus sylvatica and Picea abies forest of high biodiversity which has been protected since 1940. The other two hollows are located 400 and 700 m away in an outlying buffer zone established in 1995 which is mainly coniferous plantation forest.

The aim of the research is to analyse the landscape structure changes from the end of the Soviet times in 1974–1986 until 2005 when market economy existed in Lithuania. The changes of landscape structure were observed in 100 sample areas (squares) each of them having 2.5 km2 area and distributed in different landscape types. The changes in sample areas (squares) with determination of land cover structure transformations were observed using topographic photos and ortophoto images at a scale 1:10 000.

Rural landscape of the southern part of Lithuania as well as its use is analysed in the article. The defects of land reclamation system cause the rise of deserted lands. Dampness and bagged up soils are a large obstacle for the proper use of deserted lands. One more reason is lands of low productivity. The third reason of the rise of deserted lands is the shortage and default of perspective farmers and agricultural companies who are able to lease and cultivate land.

This paper describes the development and implementation of a method to measure the transaction costs in situations of multiple land-use, where the actions of one actor have negative effects on the other and vice versa (i.e., where the two actors’ usage patterns are interdependent). In situations where more than one agent is using a limited resource, transaction costs arise, which may affect the governance of that resource. For example, in northern Sweden the forestry and reindeer husbandry sectors incur transaction costs during consultations over land-use management.

Study was conducted in north-eastern Latvia (57° 38’ N, 22° 17’ E): in a part of Slitere National Park that was un-managed since year 1923 and affected by large storm in November of 1969. Supervised classification of Corona and Landsat 5 images of the area (in total 1646 ha) from years before and after the storm (1966–2010) were carried out and parameters characterizing the fragmentation calculated for 3 land-cover classes: forest, areas with low woody biomass and non-forest areas.

The Belgian climate policy is formulated at the federal level, requiring cooperation between regional and federal administrations. Around a fifth of the total area of Belgium is covered by forests. Around 80/ of the productive forests are in the Walloon region. Reported values for land use change and forestry categories give a potential of 2,057 kt eq. CO2 per year. Given the existing regional forest inventories (RFI): RFI1 for 1984 and RFI2 for 1999, an estimate has been made to consolidate reported data.
