Lindstad, Berit Hauger. 2002. A comparative study of forestry in Finland, Norway, Sweden, and the United States, with special emphasis on policy measures for nonindustrial private forests in Norway and the United States. Gen. Tech. Rep. PNW-GTR-538. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 35 p. In recognition of the cultural, economic, a...
abstract the aim of this study was to evaluate the status of information on forest and data transfer and to identify the gaps in information and data flow in forestry sector in iran. the study evaluated the data and information flow in three levels (control offices level, provincial offices level and organizational offices level) using the document analysis and questioning (interviews and ques...
The Darwinian concept of evolution provides a usef3 theoretical construct to consider the ongoing development of forest management and forest operations. For example, changing environments, “survival of the fittest”, and random mutation are processes, which have analogs within the forestry arena. The success and survival of any forest operations technology is determined by how well it meets the...
Landowner education is the foundation of a broad suite of public investments designed to encourage sustainable forest management. Extension Forestry programs are the primary providers of landowner education in the United States. We report the results of a census of the 50 state-level Extension Forestry Program Leaders on status, trends, and innovations in their programs. These programs employ 2...
Natural resource management literature has documented three paradigm shifts over the past decade: from co-management to adaptive co-management and adaptive governance respectively and, more recently, towards landscape governance. The latter is conceived as a governance approach towards negotiated land use at the landscape level to deal with global challenges such as food insecurity, climate cha...
There is little knowledge available regarding Australian forestry work safety and accident rates. Machine operators and forestry workers are vital parts of the forestry sector and their health and well-being can greatly impact on their work quality and efficiency. To increase our knowledge of forest workers’ safety this project aimed to analyse the frequency, type and root causes of work accide...
Forest exploitation in British Columbia is currently unsustainable. Economic analysis is frequently used to justify the high rate of cut by documenting the revenue, job and wage benefits of current industrial forestry. However, Hicks’ definition of income implies that it is poor accounting practice to count the consumption of natural capital as income. Yet in BC, economic analysis fails to make...
Current models predict that expected climate change in Ontario will significantly affect the occurrence of plant diseases in agriculture and forestry in the coming years. Direct, multiple effects on the epidemiology of plant diseases are expected, including the survival of primary inoculum, the rate of disease progress during a growing season, and the duration of epidemics. These effects will p...
During the past decade in forest mapping and monitoring applications, the ability to acquire spatially accurate, 3D remote-sensing information by means of laser scanning, digital stereo imagery and radar imagery has been a major turning point. These 3D data sets that use singleor multi-temporal point clouds enable a wide range of applications when combined with other geoinformation and logging ...
