Engelmann spruce forests are structurally and compositionally diverse, occur across a wide range of physiographic conditions, and are the result of varying disturbance histories such as fire, wind and spruce beetle. The spruce beetle is a natural disturbance agent of spruce forests and has population levels that fluctuate from endemic to epidemic. Conceptually, structural and compositional dive...

USDA Forest Service Proceedings RMRS–P–13. 2000 Abstract.— This paper presents an integrated system to support urban natural resource mcnagement. With the application of remote sensing (RS) and geographic information systems (GIS), the paper emphasizes the methodology of integrating information technology and a scientific basis to support ecosystem-based management. First, a systematic integrat...

Facing the relative lag of forest ecosystem service and estimation in China, this paper proposed to quickly carry out the research on the evaluation of forest ecosystem service. On the basis of the classification of forest ecosystem types in China, the service of artificial and semi-artificial forest ecosystems was investigated, which was divided into eight types, i.e., timber and other product...

Addressing the challenges of wildland fire requires that science be relevant to management and integrated into decisions. Co-production is often touted as a process can increase utility for management, by involving scientists managers in knowledge creation problem solving. Despite documented benefits co-production, these efforts face number institutional barriers. Further research needed on how...
