This report details how land cover and urbanization vary within the states of Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota by community (incorporated and census designated places), county subdivision, and county. Specifi cally this report provides critical urban and community forestry information for each state including human population characteristics and trends, changes in urban and community lands, tree canopy and impervious surface cover characteristics, distribution of land-cover classes, a relative comparison of urban and community forests among local...

Land managers in the Northern Forest region of Maine, New Hampshire, New York, and Vermont face the challenge of providing high-quality recreation opportunities and experiences while also protecting fragile summit resources. Th e goals of this study were to identify indicators and standards of quality for visitor experiences and summit resources for three mountains with a range of recreation opportunities. Crowding, trail condition, damage to summit soils and vegetation, and type and level of management were found to be important indicators of quality. A visitor survey identified the social,...

We conducted a self-administered mail survey in September 2009 with randomly selected Oregon hunters who had purchased big game hunting licenses/tags for the 2008 hunting season. Survey questions explored hunting practices, the meanings of and motivations for big game hunting, the constraints to big game hunting participation, and the effects of age, years of hunting experience, hunting motivations, hunting meanings, and hunting success on overall quality of experience. The study found that although hunters gave high scores to the emotional and traditional meanings of hunting, their quality...

Up to the late 20th century, most ecologists tacitly assumed that fire was not an important factor in eastern deciduous forests. Nowhere is fire mentioned in E. Lucy Braun's monographic treatment of this biome (Braun 1950). Oosting (1942) likewise omitted any mention of fire in his survey of the successional and mature communities of the eastern Piedmont. Whittaker (1956) speculated that wildfire played an important role in the maintenance of ridge top shrub and pine dominated communities of the southern Appalachians but not in deciduous hardwoods.

The northern region, which for the purposes of this paper broadly includes New England, upper mid-Atlantic, Great Lakes, central hardwood, and eastern Plains states, supports 27 percent of the Nations timber volume and 46% of its hardwood resource.

SPBLOB is a computer simulation model for the interaction between loblolly pine (Pinus taeda L.), the economically most important forest crop in the United States, and the southern pine beetle (SPB: Dendroctonus frontalis Zimm.), the major insect pest for this species. The model simulates loblolly pine stands from time of planting until harvest. It mimics day-to-day changes in SPB populations, and the associated tree mortality caused by these bark beetles. In addition, it provides yearly updates of tree mortality due to competition and of growth for the surviving trees. Chiefly, the model and...

This paper focuses on the Extension System, its history and impact over the past 100 years, and where it is heading in the future. The extension System has been referred to as the largest non- formal education network in the world. It is unique in nature, designed to help people help themselves by using research-based knowledge and information to improve their lives

Despite its importance to biodiversity and use in a variety of products, northern white-cedar (eastern white cedar; Thuja occidentalis L., referred to as cedar throughout this guide) is often considered a secondary species. It is among the least studied commercially important tree species in North America. Forest practitioners encountering cedar have little or sometimes contradictory information about its characteristics and potential. The challenges of managing for multiple objectives makes it difficult to consider cedar in silvicultural prescriptions. As a result, silvicultural treatments...

The Forest Health Monitoring Program's annual national technical report presents results of forest health analyses from a national perspective using data from a variety of sources. The report is organized according to the Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests of the Santiago Declaration. Drought in 2005 is presented, and drought over the decade 1996-2005 is compared with the historical average. The relationship between lightning frequency and forest fire occurrence is investigated. National air pollution data are used to...

In the Eastern United States, hourly ambient concentrations of ozone typically range from 30 to 50 part per billion, with events that may exceed 100ppb. Typical exposure levels can cause visible foliar injury to some plant species and have the potential to reduce tree growth by up to 10 percent per year, depending on species and environment.
