The dataset summarizes total area (km2) and proportion of Central Valley waterbird habitat, summed across individual waterbird habitats (i.e., wetland and cropland types), that was available for each of 17 projected scenarios. The dataset also includes relatively recent (year 2005) area of existing habitat (i.e., “existing area”) for comparison with areas based on scenarios. Analysis was conducted for the projection period including water-years 2006–2099 (water-year defined as October-December and January–September of the following year). Because habitat areas vary through the season with timing of crop harvest and flooding of wetlands and post-harvested fields, annual areas and proportions represent summation...
The dataset summarizes areas of Central Valley wetland and cropland waterbird habitats available for each of 17 projected scenarios by each month (August–December and following January–March). The dataset also includes relatively recent (year 2005) area of existing habitat (i.e., “existing area”) for comparison with habitat areas based on scenarios. Cropland habitats are defined as winter-flooded rice, unplowed dry rice, winter-flooded corn, unplowed dry corn, and other winter-flooded cropland (in Tulare basin). Wetlands are defined as summer-irrigated seasonal wetland, seasonal wetland that is not summer-irrigated, and semipermanent wetland (combines semipermanent and permanent wetland types). Thus, data on availability...
In this data set, records (rows) represent GPS locations of ducks marked with telemetry in California and whether locations were overlapping (within 300 m of) locations of marked ducks in other consecutive years (2015-16, 2016-17, and 2017-18) during October - March. Years 2015-16, 2016-17, and 2017-18 represented drought, non-drought, and non-drought, respectively. Matchett and company (2020; see Larger Work section for citation) summarized this data set in tables E3 and E4 to compare overlap of duck locations between consecutive years to investigate interannual habitat stability in relationship with drought, habitat management (daytime roosts and night feeding sites), and in two regions (Suisun Marsh and California...

The dataset accompanies Figures 2–4 of Matchett and Fleskes (2018) and therein the subject data are referenced as "Table A1". Data summarize peak abundance (km2) of Central Valley waterbird habitats (i.e., wetland and flooded cropland types) that are available between August and April (of the following year) for each of 17 projected scenarios by planning basin, scenario, and habitat. Area of each habitat for each scenario-basin combination is provided for the month when the most area of the respective habitat is typically flooded and available for waterbird use (i.e., January for all wetlands and winter-flooded rice and corn, and September for other winter-flooded crops in Tulare Basin). The dataset also includes...
Tabular data that represent the proportion of area classified as waterfowl habitat for each of three series of habitat maps were developed based on water distributed across the Central Valley and Suisun Marsh in California during October-March of 2014-15 through 2017-18. We used open water data (version without cloud-filling) publicly available on Point Blue Conservation's California Water Tracker web site and which Point Blue derived at 16-18 day intervals from mosaics of Landsat 8 imagery for the region including the Central Valley and Suisun Marsh. Each record in the data set represents a mosaic within a specific range of dates of imagery that together bound the Central Valley and Suisun Marsh spatial extent....

This data consists of observations of individual trees that were subjected to prescribed fire in western US national parks. Information on individual trees include measurements of tree live/dead status, growth, size, competition, and fire-caused damage. The data also includes estimates of plot-level vapor pressure deficit anomaly before fire. These data support the following publication: van Mantgem, P.J., Falk, D.A., Williams, E.C., Das, A.J., and Stephenson, N.L., 2020, The influence of pre-fire growth on post-fire tree mortality for common conifers in western US parks. International Journal of Wildland Fire. First posted - August 28, 2018 (available from author) Revised - Febuary 10, 2020

This data release contains code for computing the filtering properties of cyclical infiltration in a layered vadose zone in Central Valley, California. The code for computing the filtering is described in a manuscript that is under review at Vadose Zone Journal. The updated data contained in this data release are the code to compute the filtering properties of the vadose zone. This code was developed in 2018. The code uses existing data as inputs. The inputs are from a groundwater flow model for Central Valley, California, described by Faunt et al. (2009), and from a soil texture model described by Faunt et al. (2010). The inputs from Faunt et al. (2009) and Faunt et al. (2010) were released in those years and are...

These data represent tree diameter, species, mortality status, and plot attributes from 164 plots in Sequoia and Kings Canyon national parks, California. Plots were matched with local records of recent fire history to determine burn status and year burned if applicable. These data support the following publication: van Mantgem, P.J., Caprio, A.C., Stephenson, N.L. and Das, A.J., 2021. Forest Resistance to Extended Drought Enhanced by Prescribed Fire in Low Elevation Forests of the Sierra Nevada. Forests, 12(9), p.1248.
In this data set, records (rows) represent the distance between primary daytime roosts and night (feeding) locations of ducks marked with telemetry in California in years 2015-16, 2016-17, and 2017-18, during October - March. Years 2015-16, 2016-17, and 2017-18 represented drought, non-drought, and non-drought, respectively. Matchett and company (2020; see Larger Work section for citation) summarized this data set in figures E3 and E4 to compare distances moved among months, years, and for two regions (Suisun Marsh and California except Suisun Marsh). Matchett and company examined the effect of drought on distributions of ducks by evaluating differences in spatial distributions of duck locations within and among...

Matchett and Fleskes (2018) evaluated availability of wetland and agricultural habitats used by waterbirds overwintering in the Central Valley of California under 17 scenarios of projected climate, urbanization, and water supply management (for more information about scenarios see scenario description and Table 1 in Matchett and Fleskes [2018]). Central Valley waterbird habitats investigated in this research included managed flooded wetlands and croplands and dry cropland habitats. Flooded cropland habitats are defined as winter-flooded rice, winter-flooded corn, and other winter-flooded cropland (in Tulare basin). Flooded wetlands are defined as summer-irrigated seasonal wetland, seasonal wetland that is not summer...

The dataset summarizes areas of Central Valley waterbird habitats (i.e., wetland and cropland types) that are available for each of 17 projected scenarios by planning basin, scenario, habitat, and month (August – April of the following year). The dataset also includes relatively recent (year 2005) area of habitat (i.e., “existing_km2”) for comparison with habitat areas based on scenarios. In contrast with the dataset referenced as "Table A1", which solely includes the three managed, flooded cropland habitats, cropland habitats in this dataset are defined as winter-flooded rice, unplowed dry rice, winter-flooded corn, unplowed dry corn, and other winter-flooded cropland (in Tulare basin). Wetlands are defined as...

The Central Valley of California is one of the most important regions for wintering waterbirds in North America despite extensive anthropogenic landscape modification and decline of historical wetlands there. Like many other mediterranean-climate ecosystems across the globe, the Central Valley has been subject to a burgeoning human population and expansion and intensification of agricultural and urban development that have impacted wildlife habitats. Future effects of urban development, changes in water supply management, and precipitation and air temperature related to global climate change on area of waterbird habitat in the Central Valley are uncertain, yet potentially substantial. Therefore, we modeled area...
We used Point Blue Conservation Science's dynamic open-water dataset of water distribution and our telemetry data for duck locations to develop frequently updated habitat maps for the Central Valley and Suisun Marsh in California during October-March of 2014-15 through 2017-18. Telemetry data additionally was used to compare performance of each of three series of habitat maps produced. To create this tabular dataset, we intersected telemetry locations for ducks (vector point data) with habitat maps (raster mosaics) in a Geographic Information System (GIS) and attributed duck locations with map pixel values representing habitat, non-habitat, or unclassified (if data were missing). To develop maps of waterfowl habitat,...
