Environmental valuation studies in the context of developing countries have become more frequent in recent years. However, literature which reviews and examines the environmental valuation studies is limited. Thus, this paper performed a literature review on forest contingent valuation studies conducted in the Ethiopian context in the past two decades (2000 to May 2022), focusing on two specific objectives: (i) to examine amounts of resources that households are willing to pay (WTP) for forest conservation, and (ii) to identify determinants of households' WTP. Results indicate the mean lower annual WTP of USD 0.41 (2.63 birr) and...

Data on wildlife abundance is an important indicator both for the species concerned and the stability of entire ecosystems as well as for sustainable game management. Therefore, the abundance of ungulate game was verified in a foothill region of Kazakhstan. The methods of thermal imagery and faecal pellet group (FPG) census on transects were compared. The results obtained by the FPG counting method for moose (Alces alces, 0.34 individuals per 100 ha) and maral deer (Cervus elaphus sibiricus, 0.04 individuals per 100 ha) were relatively consistent with the data reported by the hunting ground tenants. Only one moose was detected by...

We studied sessile oak (Quercus petraea) growing on six dry sites to understand adaptability responses to drought stress. Pedunculate oak (Quercus robur) on a moderately dry site was tested in parallel. We analyzed accessions from mostly dry sites that were less sensitive to soil drought and found that the growth performance ranking was not the same before and after treatment. We used phenological plasticity approaches to study seed development and plant development before and after drought: the treatments included stem length, root length, and collar diameter, as well as dry above- and below-ground biomass performance. Additionally,...

Young trees (saplings) of the Norway spruce (Picea abies [L.] Karst.) regenerating populations were analysed on 7 plots in the Šumava Mts. (Bohemian Forest), on 5 plots in the Jeseníky Mts. (Eastern Sudetes), and 1 plot in the Krkonoše (Giant Mts.). All 13 plots were located at the forest altitudinal (vegetation) zones of natural Picea abies stands. Each selected tree was characterized by microscopic features of the first-year needles. The free-hand needle cross-sections were prepared from three needles of each tree and measured by digital microphotos. The following needle characteristics were measured: width, thickness, and vascular...
