Questions persist regarding whether the science of conservation biology can successfully affect environmental decision making. One of the most prominent fields of intersection between conservation science and environmental policy is public-lands debates in the United States. I reviewed the role of conservation science in the roadless-area policies of the U.S. Forest Service. Since 1971, the For...

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 survey identifies and defines innovative contracting mechanisms developed in the Forest Service Pacific Northwest Region and northern California. A survey of nine case studies reveals that several new mechanisms have facilitated ecosystem management, quality jobs, and administrative efficiencies, but at times innovation was hampered by Forest Service institutional structures and downsizing...

Much research in recent years has analyzed the ecosystem service aspect of forests, while highlighting the need for sustainable forests. Forest management mechanisms at an inter-institutional level in Japan have been identified to hinder the implementation of forest management that is focused on the equal production of ecosystem services. This study presents an institutional analysis of unsusta...

The Forest Inventory and nalysis Program (FI ) of the USD Forest Service conducts a national inventory of down woody materials (DWM) on forestland in the United States. Estimates of DWM for inventory plots occurring in eastern U.S. hardwood forests facilitate largescale assessment of hardwood forest fuel loadings and wildlife habitat. Therefore, the objectives of this study were (1) to quantify...

Natural disturbance processes are affected by both forest management and climate change. The resulting shifts in natural disturbance processes can have profound impact on the secondary successional pathways of British Columbia forest types (Ran & Swift 2013). Building an understanding of how these systems work and their potential changes over time and space is important since many forest manage...

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...
