Identification of the species for dendrochronological studies is of great relevance to understand various aspects of climate change. However, in the northwestern Himalayan region, dendroclimatological investigations are confined to conifer species, with broadleaved species being disregarded. Thus, the present study was conducted to assess the growth response of seven multipurpose tree species (MPTs), namely Bauhinia variegata, Celtis australis, Grewia optiva, Paulownia fortunei, Toona ciliata, Ulmus villosa and Melia composita to local climate variables, viz. temperature as well as rainfall (seasonal, monthly, average) and CO2 level by evaluating the...

The objective of this research is the identification of burned forest areas that occurred in Syria from September 2nd to October 15th, 2020. Forest fire risk classes were determined using Sentinel-2 images. Normalized Burn Ratio (NBR), Differenced Normalized Burn Ratio (dNBR), and Burned Area Index for Sentinel-2 (BAIS2), and Normalized Difference Vegetation Index (NDVI) were used for the identification how much the forests have been destroyed and to establish fire risk classes. According to the study results, the size of the vegetation area that was destroyed due to fire was determined, and...

Based on the measurements of the biomass of the stems of 3 699 trees of Scots pine, Norway spruce, and silver birch in Europe since 1950, it has been shown that these tree species show a reduction in biomass and wood density. These results contradict the fact that the volume of wood is directly converted to biomass using the historical values of the conversion rates. From 1950 to 2020 the biomass of 1 m3 of the stem with bark decreased on average by 80 kg (-17%) for Scots pine, by 105 kg (-22%) for Norway spruce and by 92 kg (-15%) for silver birch. The results obtained should be taken into account when assessing the technical properties of wood and...

The forest sector development in Uruguay has been based on planted forest areas, mainly with eucalyptus and pine. The Parliament passed the Forestry Law in 1987 and since then the sector has been growing rapidly. The objective of the study is to analyse the contribution of the forest sector in the Uruguayan economy, its evolution between 1997 and 2018 and its distribution in recent years. The research used information from the new National Accounts released by the Central Bank of Uruguay, and, in this framework, the forest sector is studied for the main macroeconomic variables and production. The results show that in the period 1997-2018, while the...
