Southern Appalachian forests are undergoing considerable change due to altered disturbance regimes. For example, fire exclusion has had a major impact on the structure and function of pine-hardwood ecosystems. Recently, fire has been prescribed for a variety of applications: 1) stand-replacement in the form of a mimicked wildfire, 2) site-preparation as part of a fell-and-burn prescription, and...

Visitors to National Forests in Colorado, Idaho, and Wyoming were asked how their visitation rates would change with the presence of a high-intensity crown fire, prescribed fire, and a 20-yearold high-intensity fire at the area they were visiting. By using pairwise t-tests, visitors to forests in Colorado showed a statistically significant decrease in recreation trips per year with the presence...

The key components of watershed processes are inputs in precipitation, interactions of vegetation, soil and water including evapotranspiration (water yield), overland flow (erosion), and storage and filtering (nutrients), and outputs in streamflow. Fire effects occur at the vegetation-soil interface and can result in altering overland flow and infiltration rate of water. Fire can affect infiltr...

—Fire has been an imperative ecological force that has shaped the natural history andculture of the Southeastern Coastal Plain. In the past, humans have influenced the “ natural” roleof fire in the southeast, first by Native Americans, then by Spanish and other European settlement,and finally by modern culture. As human culture developed, fire, and how it influenced wildlifepopu...

OBJECTIVES In the present study, we modified a night shift system for an ambulance service so that ambulance paramedics were assured of taking a nap, and examined the effects of this new system on the fatigue and physiological function of ambulance paramedics. METHODS Ten ambulance paramedics at a fire station in the center of a large city in Japan voluntarily enrolled as subjects in this fie...

Fire damage and tree characteristics of mixed deciduous oak woodlands were recorded after a prescription burn in the summer of 1999 on Mt. Hamilton Range, Santa Clara County, California. Trees were tagged and monitored to determine the effects of fire intensity on damage, recovery and survivorship. Fire-caused mortality was low; 2-year post-burn survey indicates that only three oaks have died f...

<p><span>This research looks about a counsel structure that uses degree-supervised snitch to consider allocated sensor networks. Level managed is proposed process combines evening out and invading together. This strategy reduces the number of possible messages by delivering them via base station mechanism, hence increasing neighborhood’s presence time. The district, which contains n...
