Does wildfire likelihood increase following insect outbreaks in conifer forests?

Creator:: Meigs, Garrett W., Campbell, John L., Zald, Harold S. J., Bailey, John D., Shaw, David C., and Kennedy, Robert E.
Abstract:: Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This study investigates landscape- and regional-scale wildfire likelihood following outbreaks of the two most prevalent native insect pests...

Comparative hazard assessment for protected species in a fire-prone landscape

Creator:: Roloff, Gary J., Mealey, Stephen P., and Bailey, John D.
Abstract:: We conducted a comparative hazard assessment for 325,000 ha in a fire-prone area of southwest Oregon, USA. The landscape contains a variety of land ownerships, fire regimes, and management strategies. Our comparative hazard assessment evaluated the effects of two management strategies on crown fire potential and northern spotted owl (Strix...

Intensifying a heuristic forest harvest scheduling search procedure with 2-opt decision choices

Creator:: Bettinger, Pete, 1962-, Boston, Kevin, and Sessions, John
Abstract:: Forest management problems with even-flow and adjacency considerations are difficult to solve optimally. A heuristic search intensification process, which uses two types of decision procedures, changes to single-decision choices (1-opt moves) and changes to two-decision choices simultaneously (2-opt moves), was used in an attempt to locate feasible and efficient solutions...

Density, ages, and growth rates in old-growth and young-growth forests in coastal Oregon

Creator:: Tappeiner, John C., Huffman, David W. (William), 1962-, Marshall, David, Spies, Thomas A., and Bailey, John D.
Abstract:: We studied the ages and diameter growth rates of trees in former Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) old-growth stands on 10 sites and compared them with young-growth stands (50-70 years old, regenerated after timber harvest) in the Coast Range of western Oregon. The diameters and diameter growth rates for the...

Prediction of understory vegetation cover with airborne lidar in an interior ponderosa pine forest

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., Gitelman, Alix, and Olsen, Michael J.
Abstract:: Forest understory communities are important components in forest ecosystems providing wildlife habitat and influencing nutrient cycling, fuel loadings, fire behavior and tree species composition over time. One of the most widely utilized understory component metrics is understory vegetation cover, often used as a measure of vegetation abundance. To date, understory...

An Adaptive Network-based Fuzzy Inference System for Rock Share Estimation in Forest Road Construction

Creator:: Ghajar, Ismael, Najafi, Akbar, Torabi, Seyed Ali, Khamehchiyan, Mashalah, and Boston, Kevin
Abstract:: This paper presents a new Rock Share Estimation (RSE) procedure that can estimate the cost of forest road construction. One of the key elements of the total cost in road construction is the cost of embankment. The proportion of the rock directly influences the price of this activity. Hence, a...

Cross-regional prediction of long-term trajectory of stream water DOC response to climate change

Creator:: Laudon, Hjalmar, Buttle, Jim, Carey, Sean K., McDonnell, Jeff, McGuire, Kevin, Seibert, Jan, Shanley, Jamie, Soulsby, Chris, and Tetzlaff, Doerthe
Abstract:: There is no scientific consensus about how dissolved organic carbon (DOC) in surface waters is regulated. Here we combine recent literature data from 49 catchments with detailed stream and catchment process information from nine well established research catchments at mid- to high latitudes to examine the question of how climate...

Reduction in carbon uptake during turn of the century drought in western North America

Creator:: Schwalm, Christopher R., Williams, Christopher A., Schaefer, Kevin, Baldocchi, Dennis D., Black, T. Andrew, Goldstein, Allen H., Law, Beverly E., Oechel, Walter C., Paw U, Kyaw Tha, and Scott, Russel L.
Abstract:: Fossil fuel emissions aside, temperate North America is a net sink of carbon dioxide at present¹⁻³. Year-to-year variations in this carbon sink are linked to variations in hydroclimate that affect net ecosystem productivity³,⁴. The severity and incidence of climatic extremes, including drought, have increased as a result of climate warming⁵⁻⁸....
