James Hatten
James is a Research Biogeographer at the USGS, Columbia River Research Laboratory.
Research Interests:
I am a research biogeographer that examines the current and future distributions of common, threatened, and endangered species. I have developed habitat models across the western U.S. for fish, birds, mammals, and reptiles. Climate-change, ecological flows, and riparian obligates are my focal areas.

Riparian restoration framework for the Upper Gila River, Arizona
This technical report summarizes the methods and results of a comprehensive riparian restoration planning effort for the Gila Valley Restoration Planning Area, an approximately 53-mile portion of the upper Gila River in Arizona (Figure 1-1). This planning effort has developed a Restoration Framework intended to deliver science-based guidance on suitable riparian restoration actions within the ecolAuthorsBruce K. Orr, Glen L.

OrrAssessing climate-change risks to cultural and natural resources in the Yakima River Basin, Washington, USA
We provide an overview of an interdisciplinary special issue that examines the influence of climate change on people and fish in the Yakima River Basin, USA. Jenni et al. (2013) addresses stakeholder-relevant climate change issues, such as water availability and uncertainty, with decision analysis tools. Montag et al.

MauleIdentifying stakeholder-relevant climate change impacts: a case study in the Yakima River Basin, Washington, USA
Designing climate-related research so that study results will be useful to natural resource managers is a unique challenge. While decision makers increasingly recognize the need to consider climate change in their resource management plans, and climate scientists recognize the importance of providing locally-relevant climate data and projections, there often remains a gap between management needsAuthorsK. Jenni, D. Graves, Jill M. Hardiman, James R. Hatten, Mark C. Mastin, Matthew G. Mesa, J. Montag, Timothy Nieman, Frank D. Voss, Alec G. MauleProjecting climate effects on birds and reptiles of the Southwestern United States
We modeled the current and future breeding ranges of seven bird and five reptile species in the Southwestern United States with sets of landscape, biotic (plant), and climatic global circulation model (GCM) variables. For modeling purposes, we used PRISM data to characterize the climate of the Western United States between 1980 and 2009 (baseline for birds) and between 1940 and 2009 (baseline forAuthorsCharles van Riper, James R.

SchwalbeModeling effects of climate change on Yakima River salmonid habitats
We evaluated the potential effects of two climate change scenarios on salmonid habitats in the Yakima River by linking the outputs from a watershed model, a river operations model, a two-dimensional (2D) hydrodynamic model, and a geographic information system (GIS). The watershed model produced a discharge time series (hydrograph) in two study reaches under three climate scenarios: a baseline (198AuthorsJames R. Hatten, Thomas R. Batt, Patrick J.

Moapa dace (Moapa coriacea) is a critically endangered thermophilic minnow native to the Muddy River ecosystem in southeastern Nevada, USA. Restricted to temperatures between 26.0 and 32.0°C, these fish are constrained to the upper two km of the Muddy River and several small tributaries fed by warm springs.

DixonHydraulic alterations resulting from hydropower development in the Bonneville Reach of the Columbia River
We used a two-dimensional (2D) hydrodynamic model to simulate and compare the hydraulic characteristics in a 74-km reach of the Columbia River (the Bonneville Reach) before and after construction of Bonneville Dam. For hydrodynamic modeling, we created a bathymetric layer of the Bonneville Reach from single-beam and multi-beam echo-sounder surveys, digital elevation models, and navigation surveys.AuthorsJames R. Hatten, Thomas R. BattA spatial model to assess the effects of hydropower operations on Columbia River fall Chinook Salmon spawning habitat
Priest Rapids Dam on the Columbia River produces large daily and hourly streamflow fluctuations throughout the Hanford Reach during the period when fall Chinook salmon Oncorhynchus tshawytscha are selecting spawning habitat, constructing redds, and actively engaged in spawning. Concern over the detrimental effects of these fluctuations prompted us to quantify the effects of variable flows on the aAuthorsJames R. Hatten, Kenneth F. Tiffan, Donald R. Anglin, Steven L. Haeseker, Joseph J. Skalicky, Howard SchallerA spatial model of white sturgeon rearing habitat in the lower Columbia River, USA
Concerns over the potential effects of in-water placement of dredged materials prompted us to develop a GIS-based model that characterizes in a spatially explicit manner white sturgeon Acipenser transmontanus rearing habitat in the lower Columbia River, USA. The spatial model was developed using water depth, riverbed slope and roughness, fish positions collected in 2002, and Mahalanobis distance (AuthorsJ.R. Hatten, M.J. ParsleyMapping and monitoring Mt. Graham Red Squirrel habitat with GIS and thematic mapper imagery
To estimate the Mt. Graham red squirrel (MGRS) population, personnel visit a proportion of middens each year to determine their occupancy (Snow in this vol.). The method results in very tight confidence intervals (high precision), but the accuracy of the population estimate is dependent upon knowing where all the middens are located. I hypothesized that there might be areas outside the survey bounAuthorsJames R. Hatten, John L. Koprowski - Web Tools
