Owned by individuals, families, corporations, and other private groups, private forests account for almost 60% of all forestland in the conterminous United States and provide critical habitat for wildlife, including over 3,700 at-risk plant and animal species. Extensive areas of private forest and other land covers have experienced increased housing development in recent years, with numerous implications for wildlife conservation. Twenty-eight percent of all private forests are under corporate ownership and provide important wildlife habitat. In some areas of the country, large amounts of private forest under corporate ownership are being sold and, in some cases, subdivided, with consequent implications for at-risk species conservation. Sponsored by the US Forest Service, the Forests on the Edge (FOTE) project uses geographic information systems to identify areas across the United States where private forests provide important services that might be detrimentally affected by increased housing and other threats. This article presents the results of FOTE research on the importance of private forests in general, and corporate forests in particular, to at-risk species. It also identifies areas across the country where future housing development on private forests could further reduce wildlife habitat. Results indicate that private forests and private corporate forests in the West Coast states, parts of the Gulf and Atlantic Coasts, as well as interior areas of the Southeast provide habitat for a large number of at-risk species and that these areas are also among those where private forests are most likely to experience increased housing development. © 2010 by the Society of American Foresters.

This study is a proof of concept of the sensitivity of grassfire propagation to vertical shear in the near-surface environmental flow found through four comparative grassfire numerical simulations with a coupled wildfire-atmosphere model. A unidirectional constant wind field, under neutral atmospheric conditions, no surface friction, Coriolis force or topography, and homogeneous fuel, prescribes the model environment. By using the same surface (at 6.2 m above ground level) wind speed for all simulations, analyses of the results can suggest when the behavior and spread rate of the fire may depend more on the interaction of the fire plume with the shear in the above surface wind or more on the magnitude of the mean upstream surface wind speed at the surface. Three aspects of wildfire behavior are investigated: impact of unidirectional vertical shear on surface flow properties and fire line propagation; variability in fire spread and area burnt due to the evolution of the surface flow; and implications of low-level vertical wind shear on the prediction of wildfire, especially extreme or erratic, behavior. Key Points Above-surface wind affects wildfire propagation, behavior, prediction Vertical-wind-shear/fire-interaction can be cause of erratic wildfire behavior A probability forecast for fire behavior is necessary ©2013.
