SYNMAP is a new joint I-km global land cover product with improved characteristics for land cover parameterization of the carbon cycle models that reduces land cover uncertainties in carbon budget calculations. The overall advantage of the SYNMAP legend is that all classes are properly defined in terms of plant functional type mixtures, which can be remotely sensed and include the definitions of leaf type and longevity for each class with a tree component. SYNMAP is currently used for parameterization in a European model intercomparison initiative of three global vegetation models: BIOME-BGC, LPJ, and ORCHIDEE. Corroboration of SYNMAP against GLCC, GLC2000 and MODIS land cover products reveals improved agreement...

This coverage was digitized at the USA EPA from the 1979 Physiographic Regions Map produced by the Bureau of Land Management, which added 10 physiognomic types to Kuchler's 1966 USGS Potential Natural Vegetation map (and similarly differs from the 1985 US Geological Survey map revised by Kuchler and others) The dataset consists of two thematic layers a) Vegetation Form and b) Vegetation Type. Dataset is a polygon coverage with 6700 meter mean consecutive point spacing. Data for Oregon and Washington (USA) were extracted using USGS HUC5 watersheds. Vegetation codes/names were then reclassified (cross-walk) to fit the vegetation codes/types used by the model MC1 using the WWETAC biogeography option.

This product is one of a set of mapped model simulation results generated for a project called “Global Climate Change and California: Potential Implications for Ecosystems, Health, and the Economy”. The project was conducted by the Electrical Power Research Institute (EPRI) and funded by the California Energy Commission’s Public Interest Energy Research (PIER) Program. The project was the most detailed study ever undertaken on the potential effect of climate change on California. The work examined a broad array of potentially affected sectors as well as the interactions between climate change and increased population, economic growth, and technological change. It considered a wide range of climate change scenarios,...

The mapped area is located in southeastern Arkansas where it is bounded on the north and east by the mainstem levee systems along the Arkansas and Mississippi Rivers, and on the west by uplands.  The basin continues into Louisiana to the south, but the coverage of this map extends only to the state line, incorporating approximately 1.24 million acres. Separate maps cover the Louisiana portion of the basin as well as the Macon Ridge upland and Ouachita River lowland. There are two separate lowland areas partly separated by the northern end of Macon Ridge that are collectively referred to as the Boeuf-Tensas Basin. The Boeuf Basin is a narrow lowland on the west that consists of sediments deposited in past...

The Tensas Basin portion of the study area is that part of the Mississippi Alluvial Valley within Louisiana that is bounded by the Mississippi River mainstem levee on the east, Macon Ridge and the uplands southwest of Sicily Island on the west, the Red River levee on the south, and the Arkansas State line on the north. The Tensas River and Bayou Macon are the principal streams in the northern and central parts of the study area, and Black River drains the southern part, where it is formed from the confluence of the Tensas with the Ouachita River entering the basin from the west. Various smaller streams arise within the basin and flow to one of those major drainages. The Mississippi River on the eastern boundary...

Wenatchee Extent - These are an offshoot of the Series layer and a predecessor to the Plant Association Group (PAG) layer. Potential Natural Vegetation (PNV) refers to the plant community that would be established if all successional sequences were completed without human interference under the present environmental conditions, including those created by humans. PNV is a useful tool to stratify the landscape into basic units of land capability. PNV maps should, by design, be rather stable. They may, however, be refined or updated as better information becomes available. In comparison, the concept of existing vegetation is based on the composition and arrangement of plants that exist today. Existing vegetation is...

This dataset was created by performing spatial adjustments on the original Kuchler dataset in order to correct for geometric distortions identified in the digital source data. The adjustment was performed manually in ArcGIS 10.0 using the rubbersheeting adjustment method. Note that alignment errors may still be present in this dataset, particularly towards the center of United States where displacement links were not used during the spatial adjustment process. Source Data: ftp://ftp.ngdc.noaa.gov/Solid_Earth/Ecosystems/CEOS_Ecoregions/datasets/b13/ek.htm Source Data Description: This coverage was digitized at the USA EPA from the 1979 Physiographic Regions Map produced by the Bureau of Land Management,...
Kuchler's Potential Natural Vegetation (PNV) map refined by the Fire Science Laboratory, Rocky Mountain Research Station (US Forest Service) to match terrain using a 500 meter Digital Elevation Model,4th Code Hydrologic Units, and Ecological Subregions (Bailey's Sections). These biophysical data layers were integrated with current vegetation layers to develop generalized successional pathway diagrams. Expert regional panels refined the PNV map based on these successional pathways. Originally, these coarse-scale data were developed for national-level planning. Specifically, we used this data set in the Sage-grouse Conservation Assessment. Kuchler (1964) defined potential natural vegetation as "the vegetation...

The area designated as the Ouachita Basin for the purposes of this mapping effort is that portion of the Mississippi Alluvial Valley within Louisiana that includes the Ouachita River lowlands and Macon Ridge. Although the Ouachita River is the largest stream present, the lowland portion of the study area is usually considered to be part of the Bouef Basin, one of six major lowland areas that comprise the Mississippi Alluvial Valley. Macon Ridge is not normally considered part of any lowland basin but is included in this PNV mapping effort as part of the Ouachita Basin, because most of the internal drainage of Macon Ridge flows to the Ouachita lowlands. Â The landscape of the Ouachita Basin includes unique features,...

The Bayou Meto Basin drains most of the Mississippi Alluvial Valley lowlands immediately north and east of the Arkansas River as well as part of the Grand Prairie. Bayou Meto and Bayou Two Prairie are the only major streams in the basin. The Bayou Meto Basin is the smallest of the four major basins in the Delta Region of Arkansas, comprising approximately 827,000 acres. There are three distinct geomorphic surfaces within the Bayou Meto Basin, although all are products of the Arkansas River and all are composed of features typical of meandering rivers, such as point bar, backswamp, natural levee, and abandoned channel deposits. The lowest and most recent surface is sometimes called the Arkansas Lowlands.Â...

The Yazoo Basin is located in northwestern Mississippi where it is bounded on the east by rolling uplands and on the west by the mainstem levee system along the Mississippi River. It is about 200 miles long, extending from Memphis to Vicksburg, and has an area of about 7,600 square miles. Except during major floods, surface water entering the Yazoo Basin arrives as precipitation or as runoff from the hills along the eastern flank of the basin. The only surface outlet is through the Yazoo River, which enters the Mississippi River at the southern end of the basin near Vicksburg. Most surface water discharge in the Yazoo River originates in the uplands along the eastern flank of the basin and is carried to the Yazoo...

REVISED JUNE 2013The St. Francis Basin lies in northeastern Arkansas and southeastern Missouri. This map includes only the Arkansas portion of the basin. The eastern boundary is defined by the mainstem Mississippi River levee, and the western boundary is Crowley’s Ridge.  More than 2 million acres are included in the mapped area. The principal streams are the St. Francis, Tyronza, and Little Rivers. Within Arkansas, approximately half the St. Francis Basin is made up of recent (Holocene) meander belt deposits of the Mississippi River and smaller streams. These include poorly-drained backswamps, better-drained point bars, and well-drained natural levees. Abandoned channel segments form crescent-shaped...
