The AA. assert that only through profitable management of forests for timber and non-timber products can forest cover be maintained in competition with pressures to convert forest land to other uses. This sustainability concept is important, since
parks can provide protection for only a small fraction of the remaining forests in Latin America.―(DWG)
Possible impact of climatic change on forested landscapes in Central Europe: a review
Central Europe ; Climatic variability ; Climatic variation ; Climatic warming ; Ecosystem ; Europe ; Forest ; Forestry ; Impact ; Landscape ; Palynology
This paper briefly reviews and tentatively discusses 1) former climatic changes and their impact on forests, 2) the impact of climatic warming on the genetic constitution of forest trees, their physiological processes, and the possible alteration
of forest environments, 3) the changes in the latitudinal and altitudinal zonation of forests, 4) the repercussions of possible diseases and pests on the vitality of forests, and 5) changes in the function of forests in Central European landscapes.

Climate change and boreal forest fires in Fennoscandia and central Canada
Canada ; Climatic variation ; Cold area ; Europe ; Forest ; Forest fire ; Impact ; Landscape ; Ontario ; Scandinavia
This paper's hypothesis is that, just as summer climate warming in Canada has produced dramatic increases in the number and total area of forest fires, so tool will any increase in summer temperatures in Fennoscandia. If this is so, complacency
concerning the current low level of forest fires in Fennoscandia is misplaced. Likewise, temporal variations in forest have induced important changes in Canadian landscapes, and the same may be true of Fennoscandia if increased forest fire occurrence
The A. assesses the decline of the forest around Fora Ades in Harerge region through human impact and the dilemma posed by its preservation and needs of local people.―(DWG)
Forest development on Rakata, Panjang and Sertung : contemporary dynamics (1979-1989)
Biogeography ; Forest ; Indonesia ; Island ; Multivariate analysis ; Vegetation dynamics ; Volcanic eruption ; Volcanism
Ten years of quantitative studies of forests on Krakatau demonstrate the vegetational difference resulting from multiple successional pathways. Multivariate analysis of the forest data indicates strong statistical separation of forest types within
and between the islands. Current rates of forest growth and change within the Krakatau islands are found to vary considerably. Results and discussion.
Third World meets First World in the West Coast region of the South Island : possum hunting and the role of social forestry in indigenous forest management
Environment ; Fauna ; Forest ; Forest resources ; Forestry ; New Zealand ; Resource management ; South Island
The radical change in forest policy has profound implications for the West Coast, and an alternative to the conventional forest management framework is required which recognises the Government's desire to protect the indigenous forest cover, yet
Fire history of a ponderosa pine/Douglas fir forest in the Colorado front range
Biogeography ; Colorado ; Dating ; Fire ; Forest ; Forestry ; Mountain ; United States
The main objectives of this study are : 1) to characterize the fire regime of an area of montane forest in the Colorado Front Range; and 2) to compare the utility of the different methods of dating fires in these forests.
Diversity and disturbance in a Colorado subalpine forest
Colorado ; Forest ; Mountain ; United States ; Vegetation ; Vegetation degradation ; Vegetation dynamics ; Wind
Diversity of understory plant species in a disturbed subalpine forest in the Colorado Rockies was examined to explore the hypothesis that intermediate levels of disturbance generate and maintain high levels of diversity. The AA. use a natural
experiment, where a severe but patchy windstorm damaged the canopy of a subalpine forest in the Colorado Front Range in 1974. The results suggest that intermediate levels of disturbance severity may offer more microhabitats, at least temporarily, for a wider
Relationships between forest fire and hill-slope hydrology in the Selva region of Catalonia are studied. This paper summarises the results of about 150 rainfall simulation experiments and presents an overview of work carried out so far.
In order to evaluate the soil loss in a burnt forest and the role played by slope orientation in erosion, a study has been carried out in the Montserrat area (NE Spain) affected by a fire in summer 1986.

Building in Israel throughout the Ages -one cause for the destruction of the cedar forest of the Near East
Archeological site ; Deforestation ; Dendrology ; Forest ; Historical geography ; Human impact ; Israel
The aim of this paper is to present the use of cedar wood in the buildings in one particular area-Israel, throughout the ages, which can represent general cause for the deforestation of the cedar forests of the Levant. The contribution of this paper
A study on climatic resources and allocation of economic forest/fruit in the eastern part of the subtropical region of China
action of multiple climatic factors into account. According to the analysis of the climatic conditions for high quality and high-yield subtropical economic forest and fruit, it was proposed that subtropical economic forest and fruit production bases could
Four pollen sequences along a transect from north-central Iowa to southeast Wisconsin reveal the distribution of prairie and forest during the Holocene and test the use of pollen isopolls in locating the Holocene prairie-forest border.
