United States Forest Disturbance Trends Observed Using Landsat Time Series

Creator:: Masek, Jeffrey G., Goward, Samuel N., Kennedy, Robert E., Cohen, Warren B., Moisen, Gretchen G., Schleeweis, Karen, and Huang, Chengquan
Abstract:: Disturbance events strongly affect the composition, structure, and function of forest ecosystems; however, existing US land management inventories were not designed to monitor disturbance. To begin addressing this gap, the North American Forest Dynamics (NAFD) project has examined a geographic sample of 50 Landsat satellite image time series to assess...

A Landsat time series approach to characterize bark beetle and defoliator impacts on tree mortality and surface fuels in conifer forests

Creator:: Meigs, Garrett W., Kennedy, Robert E., and Cohen, Warren B.
Abstract:: Insects are important forest disturbance agents, and mapping their effects on tree mortality and surface fuels represents a critical research challenge. Although various remote sensing approaches have been developed to monitor insect impacts, most studies have focused on single insect agents or single locations and have not related observed changes...

An interdisciplinary framework for evaluating 19th century landscape paintings for ecological research

Creator:: Warren, Dana R., Loeb, Harper M., Betjemann, Peter, Munck, Isabel A., Keeton, William S., Shaw, David C., and Harvey, Eleanor J.
Abstract:: As we contemplate the future of forest landscapes under changing climate conditions and land-use demands, there is increasing value in studying historic forest conditions and how these landscapes have changed following past disturbances. Historic landscape paintings are a potential source of data on preindustrial forests with highly detailed, full-color depictions...

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...

Impacts of disturbance on the terrestrial carbon budget of North America

Creator:: Kasischke, Eric S., Amiro, Brian D., Barger, Nichole N., French, Nancy H. F., Goetz, Scott J., Grosse, Guido, Harmon, Mark E., Hicke, Jeffrey A., Liu, Shuguang, and Masek, Jeffrey G.
Abstract:: Because it is an important regulator of terrestrial carbon cycling in North America, extensive research on natural and human disturbances has been carried out as part of the North American Carbon Program and the CarboNA project. A synthesis of various components of this research was carried out, and the results...

The Elusive Pursuit of Interdisciplinarity at the Human–Environment Interface

Creator:: Roy, Eric D., Morzillo, Anita T., Seijo, Francisco, Reddy, Sheila M. W., Rhemtulla, Jeanine M., Milder, Jeffrey C., Kuemerle, Tobias, and Martin, Sherry L.
Abstract:: Environmental challenges are complex and require expertise from multiple disciplines. Consequently, there is growing interest in interdisciplinary environmental research that integrates natural and social science, an often arduous undertaking. We surveyed researchers interested and experienced in research at the human–environment interface to assess perspectives on interdisciplinary research. Integrative interdisciplinary research...

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...

Regional dynamics of forest canopy change and underlying causal processes in the contiguous U.S.

Creator:: Schleeweis, Karen, Goward, Samuel N., Huang, Chengquan, Masek, Jeffrey G., Moisen, Gretchen, Kennedy, Robert E., and Thomas, Nancy E.
Abstract:: The history of forest change processes is written into forest age and distribution and affects earth systems at many scales. No one data set has been able to capture the full forest disturbance and land use record through time, so in this study, we combined multiple lines of evidence to...

Comparison and assessment of coarse resolution land cover maps for Northern Eurasia

Creator:: Pflugmacher, Dirk, Krankina, Olga N., Cohen, Warren B., Friedl, Mark A., Sulla-Menashe, Damien, Kennedy, Robert E., Nelson, Peder, Loboda, Tatiana V., Kuemmerle, Tobias, Dyukarev, Egor, Elsakov, Vladimir, and Kharuk, Viacheslav I.
Abstract:: Information on land cover at global and continental scales is critical for addressing a range of ecological, socioeconomic and policy questions. Global land cover maps have evolved rapidly in the last decade, but efforts to evaluate map uncertainties have been limited, especially in remote areas like Northern Eurasia. Northern Eurasia...
