Ecological studies of mixed forests in Nopporo National Forest, Central Hokkaido, Japan. Relations between the distribution of aged forests and environmental factors
In Nopporo National Forest, thirteen forest communities which were determined by dominant species and three soil types were observed. - (SGA)
Assessing forest decline in coniferous forests of Vermont using NS - 001 Thematic Mapper Simulator data
Evaluates potential of measuring/mapping forest decline in spruce-fir forest using TM simulator data. TMS ratios of 1.65/1.23 and 1.65/0.83 micro-m bands are found to be strongly correlated with ground-based measurements of forest damage. Ratio
colour density slice images using these band ratios and images using 0.56 micro-m and 1.65 micro-m bands provide means of detecting, quantifying and mapping levels of forest decline. - (CB)
India's forests have been continuously declining in recent years due to various reasons. The satellite technology has the potential to form a basis for a monitoring system of forest cover at the national level. - (PLK)
Data from representative basins demonstrate the moderating effect of forested areas on runoff. This reduction was analysed in detail for peak discharges and runoff coefficients.
A Study of dells in the New Forest, Hampshire, England
England ; Géographie de l'Europe ; Hampshire ; New Forest ; Nivation ; Périglaciaire ; Royaume-Uni ; Solifluxion ; Vallon ; Versant
Les vallons de la New Forest sont décrits comme des creux perchés en amphithéâtre sur le bord des vallées, seuls ou en groupe sans chenal apparent. En dehors de la solifluxion, hypothèse d'une formation initiale due à la nivation. Les vallons sont
comparés aux combes crayeuses du sud de l'Angleterre et aux vallons européens. Une chronologie est proposée pour la New Forest.
Comparison of taxon calibrations, modern analogue techniques, and forest-stand simulation models for the quantitative reconstruction of past vegetation : a critique
Forstdüngung gegen negative Immissionswirkungen im Mitteilgebirgsraum (Forest fertilization against negative immission effects in the low mountain range area)
Under certain conditions fertilizers may stimulate the growth of forest stands or diminish the effect of pollutants. The author describes the influences on soil-chemical characteristics, state of nutrition and type of pollution load. He makes

A comparison with two other inventories made in forests of central and western Amazonia emphasizes both the low diversity of species and genera, and the low density of palms in these eastern Amazonian rain forests.
