The Forest Vegetation Simulator (FVS) is a forest growth and yield model developed by the United States Forest Service and is used by natural resource managers and researchers. FVS is calibrated for specific geographic areas and uses a host of simulation models to forecast forest composition and structure.
The system provides clear definitions and codes for recording plant distributions at four scales or levels, from "botanical continents" down to parts of large countries. Current users of the system include the International Union for Conservation of Nature (IUCN), and the Germplasm Resources Information Network (GRIN). [ 1 ]
The next generation of models – Earth system models (ex. CCSM, [22] ORCHIDEE, [23] JULES, [24] CTEM [25]) – now includes the important feedbacks from the biosphere to the atmosphere so that vegetation shifts and changes in the carbon and hydrological cycles affect the climate. DGVMs commonly simulate a variety of plant and soil ...
Europe: SynBioSys Europe information system of distributed European TURBOVEG databases relating to plant species, vegetation and landscape data administered by the European Vegetation Survey. When completed this will contain 30 national species lists. [12] France: Sophy, computerized phytosociological information (vegetation relevés). [13]
Vegetation classification is the process of classifying and mapping the vegetation over an area of the Earth's surface. Vegetation classification is often performed by state based agencies as part of land use, resource and environmental management. Many different methods of vegetation classification have been used.
At the end of the month, with payday a few days away, you might find yourself in a financial bind. "How can I make $100 fast? How can I get cash right now?" You've probably asked yourself that a ...

Infrared radiation is simulated as if each vegetation layer is a semitransparent plane; canopy emissivity depends on foliage density. Another difference between IBIS-2 and IBIS-1 and LSX, is that IBIS-2 uses an empirical linear function of wind speed to estimate turbulent transfer between the soil surface and the lower vegetation canopy, and ...
