Abstract One of timber harvesting purposes is moving wood from the forest to sawmills. Road network planning requires consideration for alternatives. This paper purposed determine decision-making in selection alternative road networks with utility analysis by considering economic, ecological, and social criteria. The indicator used were length road, open area, cost construction, felling, skiddi...

This paper presents an interactive planning system for forest road location. This decision support system is based on an interactive heuristic approach, within which the user contributes in a cooperative manner to the optimization process. The objective of this cooperative optimization process is to exploit the problem-domain expertise of the user in order to, on the one hand, guide the search ...

fragmentation, or breaking apart of habitats, is one of the major causes of decline in biological diversity. mature ecosystems, especially dense forests are very sensitive to this phenomenon and roads are one of the major causes of fragmentation in forest landscapes. present investigation aims to trace landscape fragmentation in dense forests of golestan national park in northeast of iran betwe...

An approach for automatic road extraction from digital aerial imagery is presented. The extraction is based on a semantic model for roads. The images are divided into different so-called “global contexts”: rural, forest, and urban. Different parts of the road model and different strategies are used in the different global contexts. In rural areas, a multi-scale approach is employed to find init...

This extension note summarizes the application of two new methods that were developed to assess the quality of forest habit that Marbled Murrelets (Brachyramphus marmoratus) use for nesting in British Columbia: air photo interpretation and low-level aerial surveys. Both methods use comparable sixlevel ranking systems that are based on the availability of forest attributes deemed important for n...

Roads provide humans with a means of mobility between destinations, be it for transportation of goods and services or as a means of connecting with others. However, roads are also known to contribute toward a number of deleterious landscape processes, such as habitat destruction and fragmentation, pollution (e.g., chemical, noise and light) and animal mortality. Few studies however have investi...

Frequent and intense anthropogenic fires present meaningful challenges to forest management in the boreal forest of China. Understanding the underlying drivers of human-caused fire occurrence is crucial for making effective and scientifically-based forest fire management plans. In this study, we applied logistic regression (LR) and Random Forests (RF) to identify important biophysical and anthr...
