This is a collaborative project to support enhanced camas prairie monitoring and synthesis of existing camas lily monitoring data in the Weippe Prairie Unit of Nez Perce National Historical Park (NEPE) and in Big Hole National Battlefield (BIHO), within the Upper Columbia Basin Network (UCBN). The NPS will work with Oregon State University (OSU) to: (1) Synthesize camas monitoring data from NEPE and BIHO dating back to 2005 with weather and soil moisture and water table data to describe how variation in climate and weather influences soil moisture and camas density and flowering rates; (2) augment the existing camas monitoring protocol with new standard operating procedures for establishing and surveying permanent...
The objective of this project is to integrate observations from multiple image acquisition platforms into a coherent time series of glacier volume changes for a variety of sites in the Pacific Northwest, including South Cascade Glacier and the others in Washington State (e.g., Mt. Olympus, Mt. Rainier, Mt. Baker). Specific objectives include: Enhancing glacier mass balance methodology by incorporating newly derived and reanalyzed geodetic records in the form of Digital Elevation Models and associated Area Altitude Distributions. Estimating regional patterns of glacier mass balance by expanding the spatial density of mass balance measurements and the geographic diversity of monitored glaciers. Understanding hydrologic...
Climate change is expected to result in changes in plant-pollinator interactions, but the severity of these changes is not yet clearly understood. This project will address both spatial and temporal effects of climate change on plant-pollinator interactions by studying butterfly and plant phenology in alpine and subalpine environments of Mount Rainier National Park (MORA). Western Washington University and the National Park Service will collaborate on several project objectives, including conducting field work at multiple meadows at MORA to collect plant and butterfly data, constructing plant phenophase profiles for common forbs, constructing butterfly emergence curves for commonly detected species, developing a...
Elevated anthropogenic nitrogen (N) emissions are causing higher rates of atmospheric N deposition (Ndep) that may saturate Cascade ecosystems with reactive N. Simultaneously, increasing global temperatures and altered circulation patterns generated by climate change are expected to strongly impact snow regimes in the Cascade Range, causing reduced snowpack, earlier snowmelt dates, and higher proportions of rain precipitation. Concern over the impacts of Ndep to sensitive, high-elevation ecosystems has prompted calls for research into its interaction with climate change and the effects of Ndep on ecosystem services. This is a collaborative project between the National Park Service and Washington State University...
The Coastal Engineering Inventory project aims to inventory, catalog and map coastal engineering projects in and adjacent to coastal units of the National Park Service (NPS). The goal is to develop a greater understanding of the extent of coastal engineering modification along our coast and provide information to allow resource managers to make better decisions about how to preserve NPS resources and allow for visitor use and recreation. This project will build upon an existing pilot study and GIS database that was completed for ten coastal parks. This collaborative project will expand the coastal engineering inventory to include an evaluation of coastal engineering impacts on NPS resources by developing a prioritized...
The Klamath Basin in Oregon and California is home to a rich abundance of natural and cultural resources, many of which are vulnerable to present and future climate change. Climate change also threatens traditional ways of life for tribal communities, who have deep connections to the region. This project sought to increase the effectiveness of regional climate change adaptation and planning by (1) developing ways to integrate traditional ecological knowledge (TEK) with western science in decision making, (2) building partnerships between tribal, academic, and government institutions, and (3) increasing future capacity to respond to climate change by engaging tribal youth. Through this project, the Quartz Valley...
This recorded presentation is from the April 17, 2014 workshop for the "Integrated Scenarios of the Future Northwest Environment" project. The recording is available on YouTube. The Integrated Scenarios project is an effort to understand and predict the effects of climate change on the Northwest's climate, hydrology, and vegetation. The project was funded by the Northwest Climate Science Center and the Climate Impacts Research Consortium.
Monthly temperature and precipitation data from 41 global climate models (GCMs) of the Coupled Model Intercomparison Project Phase 5 (CMIP5) were compared to observations for the 20th century, with a focus on the U.S. Pacific Northwest (PNW) and surrounding region. A suite of statistics, or metrics, was calculated, including correlation and variance of mean seasonal spatial patterns, amplitude of seasonal cycle, diurnal temperature range, annual- to decadal-scale variance, long-term persistence, and regional teleconnections to El Niño Southern Oscillation (ENSO). Performance, or credibility, was assessed based on the GCMs' abilities to reproduce the observed metrics. GCMs were ranked in their credibility using two...
This code computes the analytical solution for the damping of sinusoidal infiltration in variably saturated soils described by Bakker and Neiber (2009) and implemented by Dickinson et al. (2014). The usage of the code is documented in the appendix of Dickinson et al. (2014). Bakker, M., Nieber, J.L., 2009. Damping of sinusoidal surface flux fluctuations with soil depth.

To assess the current topography of the tidal marshes we conducted survey-grade elevation surveys at all sites between 2009 and 2013 using a Leica RX1200 Real Time Kinematic (RTK)Global Positioning System (GPS) rover (±1 cm horizontal, ±2 cm vertical accuracy; Leica Geosystems Inc., Norcross, GA; Figure 4). At sites with RTK network coverage (San Pablo, Petaluma, Pt. Mugu, and Newport), rover positions were received in real time from the Leica Smartnet system via a CDMA modem (www.lecia-geosystems.com). At sites without network coverage (Humboldt, Bolinas, Morro and Tijuana), rover positions were received in real time from a Leica GS10 antenna base station via radio link. When using the base station, we adjusted...
Efforts to conserve stream and river biota could benefit from tools that allow managers to evaluate landscape-scale changes in species distributions in response to water management decisions. We present a framework and methods for integrating hydrology, geographic context and metapopulation processes to simulate effects of changes in streamflow on fish occupancy dynamics across a landscape of interconnected stream segments. We illustrate this approach using a 482 km2 catchment in the southeastern US supporting 50 or more stream fish species. A spatially distributed, deterministic and physically based hydrologic model is used to simulate daily streamflow for sub-basins composing the catchment. We use geographic data...

Appropriate ecological indicators of climate change can be used to measure concurrent changes in ecological systems, inform management decisions, and potentially to project the consequences of climate change. However, many of the available indicators for North American birds do not account for imperfect observation. We propose to use correlated-detection occupancy models to develop indicators from the North American Breeding Bird Survey data. The indicators will be used to test hypotheses regarding changes in range and distribution of breeding birds. The results will support the Northeast Climate Science Center’s Science Agenda, including the science priority: researching ecological vulnerability and species response...

The percentage difference between mean modeled snow-water-equivalent (meters) on April 1 for the reference (1989-2011) climate period and mean modeled snow-water-equivalent on April 1 for the T4 climate change scenario. Reference period: the period 1989 – 2011 for the Upper Deschutes River Basin domain, for which observed historical meteorology is used for model input. T4 scenario: the observed historical (reference period) meteorology is perturbed by adding +4°C to each daily temperature record in the reference period meteorology, and this data is then used as input to the model.

The Department of the Interior and the U.S. Geological Survey have made it a priority to train the next generation of scientists and resource managers. The DOI Climate Science Centers (CSCs) are working to contribute to this initiative by building and supporting a network of students across the country who are interested in understanding climate impacts and adaptation. This project will support the development of a national communications and networking resource for early career scientists, managers, and conservation practitioners. The goal of this project is to facilitate and increase information sharing across the eight regional CSCs and consortium institutions. This will be achieved by working with and expanding...
Abstract: P-band interferometric synthetic aperture radar (InSAR) data at 5 m resolution from Kahiltna Glacier, the largest glacier in the Alaska Range, Alaska, USA, show pronounced spatial variation in penetration depth, δ P. We obtained δ P by differencing X- and P-band digital elevation models. δ P varied significantly over the glacier, but it was possible to distinguish representative zones. In the accumulation area, δ P decreased with decreasing elevation from 18±3 m in the percolation zone to 10±4 m in the wet snow zone. In the central portion of the ablation area, a location free of debris and crevasses, we identified a zone of very high δ P (34±4 m) which decreased at lower elevations (23±3 m in bare ice...
Abstract (from http://www.nature.com/articles/srep24441): The 170 National Forests and Grasslands (NFs) in the conterminous United States are public lands that provide important ecosystem services such as clean water and timber supply to the American people. This study investigates the potential impacts of climate change on two key ecosystem functions (i.e., water yield and ecosystem productivity) using the most recent climate projections derived from 20 Global Climate Models (GCMs) of the Coupled Model Intercomparison Project phase 5 (CMIP5). We find that future climate change may result in a significant reduction in water yield but an increase in ecosystem productivity in NFs. On average, gross ecosystem productivity...
Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/1752-1688.12304/abstract): The hydrologic response to statistically downscaled general circulation model simulations of daily surface climate and land cover through 2099 was assessed for the Apalachicola-Chattahoochee-Flint River Basin located in the southeastern United States. Projections of climate, urbanization, vegetation, and surface-depression storage capacity were used as inputs to the Precipitation-Runoff Modeling System to simulate projected impacts on hydrologic response. Surface runoff substantially increased when land cover change was applied. However, once the surface depression storage was added to mitigate the land cover change and increases...
