Ski runs and lifts in the BlackForest have removed vegetation cover and topsoil and caused soil erosion and solifluction. Damage varies with snow depth and duration of snow cover. Summer grazing and slope grading construction exacerbates
The historic role of the forest community in sustaining the Black Hills National Forest as a complex common property multiple use resource
Environment ; Forest ; Mine ; Nature conservation ; Resource management ; Rural community ; South Dakota ; United States of America ; Wyoming
A common property resource must be defined, and throughout the history of the Black Hills National Forest (1898 forward), there has been a community of people interested in defining and redefining it as a resource. Four historical periods
are discussed : the gold mining community, building of a forest community (interested in maintening multiple uses), fragmentation of the forest community, and progress toward a multiple-use definition. - (SLD)
A comparison of bunter sandstone scarps in the BlackForest and the Vosges in Landforms and landform evolution in West Germany.
This paper concentrates on a description of scarps in two structurally and lithologically comparable areas : the Kniebis area of the BlackForest and the Donon area of the Vosges. Differences in the geomorphodynamics can be attributed to differences
Fluvial action and valley development in the central and southern BlackForest during the Late Quaternary in Landforms and landform evolution in West Germany.
The investigations on the Holocene river activities and slope dynamics in the BlackForest and Upper Rhine Lowlands were carried out with geomorphological mehods. They include the analysis of sediments, the radiocarbon dating of organic material
Meteorological parameters were measured in mahogany-black pepper agro-forestry sites in Santa Bárbara do Pará, Brazil, in September 2001, in order to investigate the differences in microclimatic mitigation in relation to forest structure and growth
Black mats, spring-fed streams, and Late-Glacial-Age recharge in the Southern Great Basin
Black mats are prominent features of the late Pleistocene and Holocene stratigraphic record in the southern Great Basin. Faunal, geochemical, and sedimentological evidence shows that the black mats formed in several microenvironments related
to spring discharge, ranging from wet meadows to shallow ponds. Here the AA. report on the fauna found in the black mats, their C 14 ages, and the implications of these ages for major recharge periods in the region.
Moglichkeiten und Grenzen der Landbewirtschaftung in dem agraren Problemgebiet des Mittel-und Südschwarzwaldes Chances and limitations in agriculture in the middle and southern BlackForest problem regions
Within the middle and southern BlackForest areas agriculture can hardly be carried out on a profitable basis because of the region's. Many impeding conditions. The introduction of new forms of farm management and cultivation which are profitable
The investigations of the Holocene environmental changes in the southern Upper Rhine Valley and the BlackForest concentrate on the time slices II (5500-3000 BC) and III (1500 BC - 500 AD) of the DFG (German Research Organization) research program
A new face on the countryside : Indians, colonists, and slaves in South Atlantic forests, 1500-1800
Documents the ecological changes over three centuries wrought by white settlers in the southern English colonies, their multiple contacts with Indians, as well as the adaptation made by black slaves to this environment. - (DWG)
The aim of this study was to determine the changes in physical and chemical properties of the soil and plant growth in Pamukcular watershed in Artvin city, 10 years after the plantation of black locust and mixed species (black locust + stone pine
), which were used for rehabilitation of the semi-arid eroded sites in this area. As a result: Although these species didn't showed good growth in the study area black locust plantation (BLP) and mixed species plantation (MSP) had a positive impact
Land use changes in Istanbul’s Black Sea coastal regions between 1987 and 2007
, agricultural, forest, bare land, brush/grassland, and lake/pond land classes. Land use changes between 1987 and 2007 were analysed in detail. Residential areas of the Black Sea coastal regions of İstanbul increased by 122% over the two decades. Also an increase
of 55% in agriculture areas was observed, while there were decreases of 26% in forest areas and 15% in free land. It is probable that pressure on the İstanbul coastal regions will continue due to migration and rapid urbanization. Therefore, Istanbul’s
Black Sea coastal regions should be maintained using a sustainable coastal management plan.
The area of investigation is on the top of a foothill spur of the southern BlackForest that extends southwards into the Rhine valley and contains valleys which are regarded as subglacial and lateral drainage channels, respectively. The article
Detailed overview of the soils of the Breisgau in a section across the lanscapes from the Rhine to the highest mountain areas of the BlackForest. Description of the single soils by horizons and horizon property, partially an ecological land
