Most studies on frugivorous bat assemblages in secondary forests have concentrated on differences among successional stages, and have disregarded the effect of forest management. Secondary forest management practices alter the vegetation structure and fruit availability, important factors associated with differences in frugivorous bat assemblage structure, and fruit consumption and can therefor...

Half of the productive forest area in Sweden is owned by small-scale private forest owners. However, there is a lack of comprehensive information that would allow categorizing small-scale private forest owners according to their management strategy. In this study, we surveyed small-scale private forest owners in Sweden to determine the proportions who applied various management strategies. We a...

forest property (on average < 3 ha) and fragmentation (3 plots on average) (The Slovenian Forest Service, 2005). Private forest management is further hindered by constant processes in the society which are related to an increasing number of owners due to partible inheritance and the diminishing sizes of forest property as well as a fall in the percentage of rural population, which indirectly in...

This is the second part of two articles dedicated to the use of computer-based tools in the analysis of spatial information for forest management. The aim of this article is to illustrate forest practitioners the business opportunities brought by remote sensing in terms of data capture and monitoring forest resources in Britain. Some of these technologies are already mature tools ready for busi...

There is an ever-growing body of literature on forest management strategies for climate change adaptation; however, few frameworks have been presented for integrating these strategies with the real-world challenges of forest management. We have developed a structured approach for translating broad adaptation concepts into specific management actions and silvicultural practices for forest adapta...

Forests being an indispensable resource play an important role in maintaining the earth's ecological balance. The major contributors of deforestation are logging off of trees (legal or illegal), tree theft, forest fire etc. Large scale deforestation has negative impact on the atmosphere resulting in global warming, flash floods, landslides, drought etc. Due to these adverse effects, forest mana...

The Forest Monitoring Service Element of the Global Monitoring for Environmental and Security initiative aims to provide improved forest monitoring (based on space technologies) for the European and global environment. The Service Portfolio provided information on yearly carbon balance, forest disturbance data as well as information for practical forest and land use management operations for bo...

Sustainable forest management requires new tools to analyze spatial and temporal forest dynamics and to examine those forest parameters that are related to sustainability. We built a prototype system for data analysis and decision-making at forest enterprise level by integrating a forest ecosystem model EFIMOD-PRO (long-term prediction of forest growth and soil development) with an interactive ...

The Local Unit Criteria and Indicator Development (LUCID) project was a pilot project conducted from 1999 through 2002 by the USDA Forest Service Inventory and Monitoring Institute in conjunction with eight national forests on six sites to appraise the feasibility of monitoring sustainable systems at the forest management unit scale. The sustainability assessment will: provide forest managers a...
