New plantations can either cause deforestation by replacing natural forests or avoid this by using previously cleared areas. The extent of these two situations is contested in tropical biodiversity hotspots where objective data are limited. Here, we explore delays between deforestation and the establishment of industrial tree plantations on Borneo using satellite imagery. Between 1973 and 2015 ...

Changes in forested landscapes may have important consequences for ecosystem services and biodiversity conservation. In northern Spain, major changes in land use occurred during the second half of the 20th century, but their impacts on forests have not been quantified. We evaluated the dynamics of landscape and forest distribution patterns between 1957 and 2003 in Fragas do Eume Natural Park (n...

In 2016, in response to forest loss, the Myanmar government banned logging operations for 1 year throughout the entire country and for 10 years in specific regions. However, it is unclear whether this measure will effectively reduce forest loss, because disturbance agents other than logging may have substantial effects on forest loss. In this study, we investigated an approach to attribute dist...

in forest harvesting, there is an ongoing trend to increase constantly the size, power and load of logging machines. this may cause soil degradation in forest ecosystems as the passes of these machines modify important soil structural characteristics. the present study was conducted to examine impact of skidding traffic, trail slope, traffic frequency, and soil depth on bulk density and soil co...

Site studies have shown that conifer plantations in northern Britain have increased in General Yield Class (GYC) by 1 m ha" a" per decade or more (20-40 per cent) since the 1930s. Large increases in forest productivity have also occurred in many other regions of Europe. Are these increases due to improved silvicultural practices or to increases in N deposition, CO2 and temperature? Two process-...

This paper presents a model of global timber markets that captures the evolution of a broad array of forest resources and timber market margins over time. These margins include the inaccessible northern and tropical margins, plantation establishment, and timberland management. A baseline case is presented and discussed. Five alternative scenarios are then presented. These scenarios allow us to ...

Land cover in the upstream watershed area is changing rapidly due to anthropogenic activity. This study aims determine dynamics of land change Sekampung Hulu watershed. The survey used Landsat satellite imagery data for 2008, 2015, and 2021 obtained from United States Geological Survey analyzed it using guided classification with Object Oriented Classification algorithm Ecognition ArcGIS 10.3 s...
