Plant ecology is defined as the study of organisms in reciprocal relationship with their environment. Therefore forest should be a its The definition however inadequate practical forestry and since forests are to meet both physical economic needs population combines itself all these factors that affect natural importance forest. Forest management not known plant ecology, becomes an important en...

The extent to which response to environmental change is mediated by species-specific ecology is an important aspect of the population histories of tropical taxa. During the Pleistocene glacial cycles and associated sea level fluctuations, the Sunda region in Southeast Asia experienced concurrent changes in landmass area and the ratio of forest to open habitat, providing an ideal setting to test...
Many processes that are fundamental to tropical rainforest maintenance and regeneration take place in the forest canopy. Recently developed access techniques afford biologists nondestructive means to document and quantify canopy biota and their accompanying activities and interactions. Results from studies involving within-canopy observations and measurements of nutrient cycling, epiphyte distr...
Spatially-explicit harvest scheduling models that can promote the development of dynamic mature forest patches have been proposed in the past. This paper introduces a formulation that extends these models by allowing the total perimeter of the patches to be constrained or minimized. Test run results suggest that the proposed model can produce solutions with fewer, larger, and more compact patch...
Bushfircs are common in Australia. They cau:oemuch damage and considerable loss annually. However. some use could be made of these wildfires fer forest mapping if developments in colour and false-colour (colour infrared) aerial photography were more fully exploited. The advantages that colour and false-colour aerial photography have over pan~ chromatic minus-blue aerial photography are analyzed...
During the last two centuries, social perception of forest roles has suffered deep changes. New environmental roles, i.e. CO2 storage and biodiversity, have been added to erosion control and watershed regulation. These changes require new knowledge and tools to develop a new understanding of forest dynamics. Some come from studies on past vegetation responses to climate changes. I recall here s...
NED-2 is a sophisticated, intelligent, goal driven, and integrated multi-agent decision support system for forest ecosystem management. NED-2 currently integrates various forest mangement tools and models, including vegetation growth and yield models, wildlife models, management models for timber, ecology, water, and visual quality goals, GIS reporting tool, HTML report generating tool, etc.. T...
Improving public engagement in ecological research improves the visibility of science and educates a wider audience about value ecology its study. To this end, we assess success two simple activities, designed to track forest cover understorey conditions, implemented at Lammi Biological Station Science Trail, Finland, terms effective participation useability data generated. We consider how best...
