Land use ; Methodology ; Norway ; Sampling ; Survey ; Vegetation
The Norwegian area frame survey of land cover and outfield land resources is a response to the demand for reliable informations about land cover and land resources. It constitues a baseline for studying changes in outfield land resources. It uses
a systematic sampling technique. The article documents the methodology used in the survey, followed by a discussion of issues raised by the choice of methodology.

The physiographic approach in soilsurvey is extended to landscape-ecological survey. Departing from the example of an area depicted on aerial photography, a qualitative landscape description is given. (AIS).
Ubersicht über die Hangneigungsverhältnisse in der DDR auf der Grundlage der Mittelmassstäbigen Landwirtschaftlichen Standortkartierung. (Survey of GDR slope conditions on the basis of medium-scale mapping of agricultural land units)
On the basis of area recording within medium-scale mapping of agricultural land units, a survey is given of the slope conditions by slope area types. The data refers to the farmland area in the counties and at a national level and, furthermore
, classified for the individual land unit groups. (HL).

Ecoregions represent one of the largest scales in the fluvial hierarchy and are defined by recurring patterns of geology, climate, land use, soils, and potential natural vegetation. Watersheds, the next largest scale, are often nested into a single
: Ozark Highlands, Boston Mountains, and Ouachita Mountains. These ecoregions were selected because of their high-quality stream resources and diverse aquatic communities and are of special management interest to the Oklahoma Department of Wildlife

Five nineteenth-century policies for alienating the federal public domain only partially fulfilled their objectives when applied in the arid setting of Owens Valley. Public land policies were adequate for settling the well-watered north end
, but unsuccessfull in reclaiming the irrigable lands of the vast southern arid stretches.
