Status and trends of land change in selected U.S. ecoregions - 2000 to 2011 Status and trends of land change in selected U.S. ecoregions - 2000 to 2011
U.S. Geological Survey scientists developed a dataset of 2006 and 2011 land-use and land-cover (LULC) information for selected 100-km2 sample blocks within 29 U.S. Environmental Protection Agency (EPA) Level III ecoregions across the conterminous United States. The data can be used with the previously published Land Cover Trends Dataset: 1973 to 2000 to assess landuse/land-cover change...

Modelling regional land change scenarios to assess land abandonment and reforestation dynamics in the Pyrenees (France) Modelling regional land change scenarios to assess land abandonment and reforestation dynamics in the Pyrenees (France)
Over the last decades and centuries, European mountain landscapes have experienced substantial transformations. Natural and anthropogenic LULC changes (land use and land cover changes), especially agro-pastoral activities, have directly influenced the spatial organization and composition of European mountain landscapes. For the past sixty years, natural reforestation has been occurring...

The Southern Piedmont’s continued land-use evolution, 1973–2011 The Southern Piedmont’s continued land-use evolution, 1973–2011
The southern Piedmont in the U.S. was an important farming region during the 19th century, but by the end of the 20th century, agricultural land use had decreased substantially with forest becoming the majority land cover by the 1970s. Geographical literature has documented this change but has not concentrated on the region’s contemporary land uses. The Piedmont currently has three main...

Land cover trends dataset, 1973-2000 Land cover trends dataset, 1973-2000
The U.S. Geological Survey Land Cover Trends Project is releasing a 1973–2000 time-series land-use/land-cover dataset for the conterminous United States. The dataset contains 5 dates of land-use/land-cover data for 2,688 sample blocks randomly selected within 84 ecological regions. The nominal dates of the land-use/land-cover maps are 1973, 1980, 1986, 1992, and 2000. The land-use/land...

Spatially explicit modeling of 1992-2100 land cover and forest stand age for the conterminous United States Spatially explicit modeling of 1992-2100 land cover and forest stand age for the conterminous United States
Information on future land-use and land-cover (LULC) change is needed to analyze the impact of LULC change on ecological processes. The U.S. Geological Survey has produced spatially explicit, thematically detailed LULC projections for the conterminous United States. Four qualitative and quantitative scenarios of LULC change were developed, with characteristics consistent with the...

Land-use and land-cover change in three corn belt ecoregions: Similarities and differences Land-use and land-cover change in three corn belt ecoregions: Similarities and differences
Land use categorical changes, though not as numerous as one might suspect, vary by type within the three designated ecozones of the Corn Belt with the westernmost zone showing the most temporary change vis-a-vis the more permanent changes taking place in the eastern and central zones.
