Decadal Trends in Net Ecosystem Production and Net Ecosystem Carbon Balance for a Regional Socioecological System

Creator:: Turner, David P., Ritts, William D., Yang, Zhiqiang, Kennedy, Robert E., Cohen, Warren B., Duane, Maureen V., Thornton, Peter E., and Law, Beverly E.
Abstract:: Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes − notably by way of harvest removals and related impacts on net ecosystem production (NEP). In the Pacific Northwest region of the U.S., the implementation of the Northwest Forest...

The role of remote sensing in process-scaling studies of managed forest ecosystems

Creator:: Masek, Jeffrey G., Hayes, Daniel J., Hughes, M. Joseph, Healey, Sean P., and Turner, David P.
Abstract:: Sustaining forest resources requires a better understanding of forest ecosystem processes, and how management decisions and climate change may affect these processes in the future. While plot and inventory data provide our most detailed information on forest carbon, energy, and water cycling, applying this understanding to broader spatial and temporal...

Habitat selection by juvenile Swainson’s thrushes (Catharus ustulatus) in headwater riparian areas, Northwestern Oregon, USA

Creator:: Jenkins, Stephanie R., Betts, Matthew G., Huso, Manuela M., and Hagar, Joan C.
Abstract:: Lower order, non-fish-bearing streams, often termed ‘‘headwater streams’’, have received minimal research effort and protection priority, especially in mesic forests where distinction between riparian and upland vegetation can be subtle. Though it is generally thought that breeding bird abundance is higher in riparian zones, little is known about species distributions...

Carbon concentration of standing and downed woody detritus: Effects of tree taxa, decay class, position, and tissue type

Creator:: Harmon, Mark E., Fasth, Becky, Woodall, Christopher W., and Sexton, Jay
Abstract:: The degree to which carbon concentration (CC) of woody detritus varies by tree taxa, stage of decay, tissue type (i.e., bark versus wood), and vertical orientation was examined in samples of 60 tree species from the Northern Hemisphere. The mean CC of 257 study samples was 49.3% with a range...

Impacts of Swiss needle cast on overstory Douglas-fir forests of the western Oregon Coast Range

Creator:: Black, Bryan A., Shaw, David C., and Stone, Jeffrey K.
Abstract:: Tree-ring analysis was applied to assess the impacts of the fungal disease Swiss needle cast on the radial growth of mature Douglas-fir (Pseudotsuga menziesii) forests in the western Oregon Coast Range. Although considered endemic to the Pacific Northwest, Swiss needle cast has significantly lowered productivity in Douglas-fir forests only in...

A simple tool for estimating throughfall nitrogen deposition in forests of western North America using lichens

Creator:: Root, Heather T., Geiser, Linda H., Fenn, Mark E., Jovan, Sarah, Hutten, Martin A., Ahuja, Suraj, Dillman, Karen, Schirokauer, David, Berryman, Shanti, and McMurray, Jill A.
Abstract:: Anthropogenic nitrogen (N) deposition has had substantial impacts on forests of North America. Managers seek to monitor deposition to identify areas of concern and establish critical loads, which define the amount of deposition that can be tolerated by ecosystems without causing substantial harm. We present a new monitoring approach that...

Post-fire logging produces minimal persistent impacts on understory vegetation in northeastern Oregon, USA

Creator:: Peterson, David W. and Dodson, Erich Kyle
Abstract:: Post-fire forest management commonly requires accepting some negative ecological impacts from management activities in order to achieve management objectives. Managers need to know, however, whether ecological impacts from post-fire management activities are transient or cause long-term ecosystem degradation. We studied the long-term response of understory vegetation to two post-fire logging...

Canopy gaps affect the shape of Douglas-fir crowns in the western Cascades, Oregon

Creator:: Seidel, Dominik, Ruzicka, Kenneth J., and Puettmann, Klaus
Abstract:: Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...

Forest disturbance across the conterminous United States from 1985-2012: The emerging dominance of forest decline

Creator:: Cohen, Warren B., Yang, Zhiqiang, Stehman, Stephen V., Schroeder, Todd A., Bell, David M., Masek, Jeffrey G., Huang, Chengquan, and Meigs, Garrett W.
Abstract:: Evidence of shifting dominance among major forest disturbance agent classes regionally to globally has been emerging in the literature. For example, climate-related stress and secondary stressors on forests (e.g., insect and disease, fire) have dramatically increased since the turn of the century globally, while harvest rates in the western US...

Disturbance, tree mortality, and implications for contemporary regional forest change in the Pacific Northwest

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Tree mortality is an important demographic process and primary driver of forest dynamics, yet there are relatively few plot-based studies that explicitly quantify mortality and compare the relative contribution of endogenous and exogenous disturbances at regional scales. We used repeated observations on 289,390 trees in 3673 1 ha plots on...
