Recently, increasing attention has been paid to the anthropogenic degradation of the riverbed and its relationship to the ecological status of the adjacent river landscape. The key objective of this r...
Land Use Changes, Disturbances, and Their Interactions on Future Forest Aboveground Biomass Dynamics in the Northern US
Landsat national forest inventory sensitivity analysis uncertainty
2024/3/5
Land use change (LUC), disturbances, and their interactions play an important role in regional forest carbon (C) dynamics. Here we quantified how these activities and events may influence future above...
Modelling forest dynamics in a nature reserve: a case study from south-central Sweden

In an Island of the Netherlands, Pine (Pinus nigra) was planted to stabilize the dunes and to protect the arable lands from the blowing sand. This research was conducted to understand the most importa...
Site classification vs. wood production: a case study based on Silver fir growth dynamics in the Western Carpathians
Western Carpathians site classification production potential Silver fir growth model
2015/3/27
We analysed wood production on an example of Silver fir growth ability within site units defined in the site classification that is currently used in the Western Carpathians. It has arisen as a very i...
