Wildfire has brought about ecological, economic, and social consequences that engender human responses in many parts of the world. How to respond to wildfire risk is a common challenge across the globe particularly in areas where lands are controlled by many small private owners because effective wildfire prevention and protection require coordinated efforts of neighboring stakeholders. We expl...

Unasylva 231/232, Vol. 60, 2009 Forest adaptation to future environmental or social conditions resulting from climate change may significantly alter how and why forestry is practised in many parts of the globe. With the climate, and as a result the environment, undergoing perceptible changes within the life span of trees, achieving sustainable forest management will increasingly resemble aiming...

In this paper, we present an approach of employing multiobjective optimization to support decision making in forest management planning. The planning is based on data representing so-called stands, each consisting of homogeneous parts of the forest, and simulations of how the trees grow in the stands under different treatment options. Forest planning concerns future decisions to be made that in...

the present research was performed in patom, namkhaneh, gorazbon, chelir and baharbon districts in kheyrud forest. due to existence of forest typology map and extension of study area, this study was confined to beech dominated forests. a stratified sampling method based on landform is used to locate 1000 m2 circular sample plots. the number of fagus orientalis lipsky trees ? 7.5 cm in dbh withi...

This paper describes research on the use of a multiobjective genetic algorithm (GA) to optimize prescriptive treatment plans for forest management. The algorithm is novel, in that (1) the plans generated by the algorithm are highly specific, stating precisely when and where treatments are to be applied; and (2) logical rules and inference engines developed for a decision support system are used...

Development of the Northwest Forest Plan (NWFP) was motivated by concerns about the over-harvest of late-seral forests and the effects of intensive forest management on the long-term viability of the Northern Spotted Owl (Strix occidentalis caurina). Following several years of intense political and legal debates, the final NWFP was approved in 1994. Even though the plan evolved with a broad eco...

The Northwest Forest Plan in the Pacific Northwest, United States includes directives for survey and site protection of hundreds of rare species across many taxonomic classes. To help direct survey activities, prioritize sites, and stand conditions for conservation of these species, I developed Bayesian belief network (BBN) models of habitat relationships and multiple stressors predicting prese...

Parks and Protected Areas (PPA) have become increasingly important for societal well-being in Europe and the United States. Urbanization, detachment from nature, and demographic changes are fostering discussions about strengthening the social and cultural dimensions of management. The complexities and subtleties of incorporating PPAs into existing government and societal contexts are explored w...
