Settlement Design, Forest Fragmentation, and Landscape Change in Rondônia, Amazônia
Deforestation and colonization in Amazônia have attracted substantial attention. This article focuses on an area of 3,000 km2 within the Brazilian State of Rondônia. Two adjacent settlements were compared to assess the role of their different designs in landscape change. Anari was planned following an orthogonal road network. Machadinho was designed with attention to topography in laying out ro...
متن کاملThermokarst rates intensify due to climate change and forest fragmentation in an Alaskan boreal forest lowland.
Lowland boreal forest ecosystems in Alaska are dominated by wetlands comprised of a complex mosaic of fens, collapse-scar bogs, low shrub/scrub, and forests growing on elevated ice-rich permafrost soils. Thermokarst has affected the lowlands of the Tanana Flats in central Alaska for centuries, as thawing permafrost collapses forests that transition to wetlands. Located within the discontinuous ...
متن کاملIs forest fragmentation driven by the spatial configuration of land quality? The case of western Oregon
We investigated spatial configuration of economic returns, to enhance models of forest fragmentation for western Oregon and western Washington. Drawing from spatial land rent theory, economic drivers of forest fragmentation at the landscape level include land quality comprised of attributes such as soil fertility or the distance of urban plots to amenities. We included the spatial configuration...
متن کاملForest Landscape in Europe: Pattern, Fragmentation and Connectivity Forest Landscape in Europe: Pattern, Fragmentation and Connectivity
The JRC demonstrated the feasibility to assess and report in a harmonized manner, forest landscape pattern and fragmentation in Europe, on the basis of an easily reproducible set of indices. Results were used in the Forest EUROPE, UN ECE and FAO joint ministerial reporting process on the protection of forests in Europe where data on forest pattern do not exist from national forest inventories. ...
متن کاملEffects of climate change and shifts in forest composition on forest net primary production.
Forests are dynamic in both structure and species composition, and these dynamics are strongly influenced by climate. However, the net effects of future tree species composition on net primary production (NPP) are not well understood. The objective of this work was to model the potential range shifts of tree species (DISTRIB Model) and predict their impacts on NPP (PnET-II Model) that will be a...
