The Elwha River Restoration Project...
... has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington. Coordinated by the National Park Service, restoration of the Elwha River included the removal of two large dams that had blocked salmon and sediment passage for almost 100 years. The largest dam removal in U.S. history began in...
Maintaining a current understanding of ecological conditions is fundamental to the National Park Service in meeting its mission to preserve park resources in an unimpaired state for future generations. Ecological monitoring establishes reference conditions, which over time help to define the normal limits of natural variation, determine standards for comparing future changes, and identify the...
National parks and other protected areas are key components of the wildlife conservation landscape. The goal of wildlife managers in national parks is to preserve the ecological integrity and authenticity of natural systems for future generations. Wildlife populations of national parks, however, are in continuous flux as a result of changing land uses outside their boundaries, climate...
Trends in landbird density at two national parks in fragmented, mixed-use landscapes of the Pacific Northwest
National parks play a key role in conserving species by providing landscapes where threats from anthropogenic disturbance are reduced. In a recent study of 3 large wilderness parks in the Pacific Northwest, nearly all landbird species were found to be stable or increasing. Nonetheless, contemporary results from the Breeding Bird Survey and mark-...Holmgren, M.; Wilkerson, R.; Siegel, R.; Ransom, J.; Jenkins, Kurt J.; Boetsch, J.; Ray, Chris; Holmgren, Mandy; Wilkerson, Robert L.; Siegel, Rodney B.; Boetsch, John R.; Jenkins, Kurt J.; Ransom, Jason I.
Natural resource condition assessment: Olympic National Park
The Natural Resource Assessment Program aims to document condition and trends of selected park resources while identifying emerging issues and information needs. This information is intended to serve as a platform for natural resource managers to use in developing future resource stewardship priorities and planning.Olympic National Park (OLYM) on...Mccaffery, Rebecca; Jenkins, Kurt J.
Landbird population trends in mountain and historical parks of the North Coast and Cascades Network: 2005–2016 synthesis
Long-term monitoring of landbird populations within the National Park Service (NPS) North Coast and Cascades Inventory and Monitoring Network (NCCN) began in 2005, with the goal of detecting trends to inform the conservation and management of landbirds and their habitats. Here we use 2005–2016 data from over 3500 point-count stations to report...Ray, Chris; Saracco, James F.; Holmgren, Mandy; Wilkerson, Robert L.; Siegel, Rodney B.; Jenkins, Kurt J.; Ransom, Jason I.; Happe, Patricia J.; Boetsch, John R.; Huff, Mark H.
Reply to ‘Wolf-triggered trophic cascades and stream channel dynamics in Olympic National Park: a comment on East et al. (2017)’ by Robert Beschta and William Ripple

Development of a robust analytical framework for assessing landbird trends, dynamics and relationships with environmental covariates in the North Coast and Cascades Network
During 2015-2016, we completed development of a new analytical framework for landbird population monitoring data from the National Park Service (NPS) North Coast and Cascades Inventory and Monitoring Network (NCCN). This new tool for analysis combines several recent advances in modeling population status and trends using point-count data and is...Ray, Chris; Saracco, James; Jenkins, Kurt J.; Huff, Mark; Happe, Patricia J.; Ransom, Jason I.
Recent stability of resident and migratory landbird populations in National Parks of the Pacific Northwest
Monitoring species in National Parks facilitates inference regarding effects of climate change on population dynamics because parks are relatively unaffected by other forms of anthropogenic disturbance. Even at early points in a monitoring program, identifying climate covariates of population density can suggest vulnerabilities to future change....Ray, Chris; Saracco, James; Holmgren, Mandy; Wilkerson, Robert; Siegel, Rodney; Jenkins, Kurt J.; Ransom, Jason I.; Happe, Patricia J.; Boetsch, John; Huff, Mark
Channel-planform evolution in four rivers of Olympic National Park, Washington, U.S.A.: The roles of physical drivers and trophic cascades
Identifying the relative contributions of physical and ecological processes to channel evolution remains a substantial challenge in fluvial geomorphology. We use a 74-year aerial photographic record of the Hoh, Queets, Quinault, and Elwha Rivers, Olympic National Park, Washington, U.S.A., to investigate whether physical or trophic-cascade-driven...East, Amy E.; Jenkins, Kurt J.; Happe, Patricia J.; Bountry, Jennifer A.; Beechie, Timothy J.; Mastin, Mark C.; Sankey, Joel B.; Randle, Timothy J.
Interagency Pacific marten (Martes caurina) distribution study on the Olympic Peninsula, Washington
The objective of this study was to determine if the Pacific marten (Martes caurina) still occurs on the Olympic Peninsula in Washington State. We reviewed recent records of marten observations on the Olympic Peninsula since 1998, and conducted new surveys in undersampled regions of the Olympic Peninsula during summer, 2016. We reviewed evidence...Moriarty, Katie; Howell, Betsy; Morozumi, Connor; Happe, Patti; Jenkins, Kurt J.; Aubry, Keith B.
Mountain goat abundance and population trends in the Olympic Mountains, northwestern Washington, 2016
Executive SummaryWe estimated abundance and trends of non-native mountain goats (Oreamnos americanus) in the Olympic Mountains of northwestern Washington, based on aerial surveys conducted during July 13–24, 2016. The surveys produced the seventh population estimate since the first formal aerial surveys were conducted in 1983. This was the second...Jenkins, Kurt J.; Happe, Patricia J.; Beirne, Katherine F.; Baccus, William T.
Evaluation of fisher (Pekania pennanti) restoration in Olympic National Park and the Olympic Recovery Area: 2015 final annual progress report
With the translocation and release of 90 fishers (Pekania pennanti) from British Columbia to Olympic National Park during 2008–2010, the National Park Service (NPS) and Washington Department of Fish and Wildlife (WDFW) accomplished the first phase of fisher restoration in Washington State. Beginning in 2013, we initiated a new research project to...Happe, Patricia J.; Jenkins, Kurt J.; Kay, Thomas J.; Pilgrim, Kristie; Schwartz, Michael K.; Lewis, Jeffrey C.; Aubry, Keith B.
Landscape-scale habitat selection by fishers translocated to the Olympic Peninsula of Washington
The fisher was extirpated from much of the Pacific Northwestern United States during the mid- to late-1900s and is now proposed for federal listing as a threatened species in all or part of its west coast range. Following the translocation of 90 fishers from central British Columbia, Canada, to the Olympic Peninsula of Washington State from 2008...Lewis, Jeffrey C.; Jenkins, Kurt J.; Happe, Patricia J.; Manson, David J.; McCalmon, Marc
Timing of translocation influences birth rate and population dynamics in a forest carnivore
Timing can be critical for many life history events of organisms. Consequently, the timing of management activities may affect individuals and populations in numerous and unforeseen ways. Translocations of organisms are used to restore or expand populations but the timing of translocations is largely unexplored as a factor influencing population...Facka, Aaron N; Lewis, Jeffrey C.; Happe, Patricia; Jenkins, Kurt J.; Callas, Richard; Powell, Roger A.
The USGS and National Park Service (NPS) have published the first Natural Resource Condition Assessment for Olympic National Park. A Natural Resource Condition Assessment, or NRCA, is a report that evaluates a subset of important natural resources in a NPS Unit.
The state-threatened western gray squirrel occurs in the northern Cascade Range, Washington, where long-term fire suppression has increased risk of catastrophic wildfire.
Scientists from USGS, NPS, and the Institute for Bird Populations developed a new framework for analyzing landbird population monitoring data from the NPS North Coast and Cascades Inventory and Monitoring Network (NCCN).
