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 summer-irrigated seasonal wetland, seasonal wetland that is not summer irrigated, and semipermanent wetland (combines semipermanent and permanent wetland types). Also in contrast with the "Table A1" dataset, these data include habitat areas for each month of August– April, and for Suisun Basin in addition to the other eight basins defined in the Central Valley Joint Venture Implementation Plan (2006). Data on availability of waterbird habitats is summarized by planning basin, scenario, habitat, and month in 5 metrics (in addition to existing area): the least available area; areas available in ≥ 25%, ≥ 50%, and ≥ 75% of years; and maximum available area. These data support the following publication: Matchett EL, Fleskes JP. 2018. Waterbird habitat in California’s Central Valley basins under climate, urbanization, and water management scenarios.

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 relatively recent (year 2005) area of habitat (i.e., “existing_km2”) for comparison with habitat areas based on scenarios. Flooded cropland habitats are defined as winter-flooded rice, winter-flooded 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). This dataset includes results for eight of nine basins defined by the Central Valley Joint Venture in the Central Valley Joint Venture Implementation Plan (2006); subject basins are the Colusa, Butte, Sutter, American, Yolo, Delta, San Joaquin, and Tulare Basins (Suisun Basin excluded). Data on availability of waterbird habitats is summarized by planning basin, scenario, habitat, and month in 5 metrics (in addition to recent historical area): the least available area; areas available in ≥ 25%, ≥ 50%, and ≥ 75% of years; and maximum available area.

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 irrigated, and semi-permanent wetland (combines semipermanent and permanent wetland types). Dry cropland habitats include unplowed dry corn and unplowed dry rice fields. Two datasets documented herein accompany Matchett and Fleskes (2018), and for each of the 17 scenarios, these datasets summarize available area (km2) of each habitat during August–April (of the following year). The first of these datasets, “Table A1” (also referenced as Table A1 in Matchett and Fleskes [2018]), corresponds with areas of available habitat in Figures 2–4 of Matchett and Fleskes (2018). Table A1 summarizes available area (km2) of each flooded habitat by planning basin and scenario when available habitat area is typically highest during the wintering period. The second dataset, “Table A2” (also Table A2 in Matchett and Fleskes [2018]), corresponds with areas of available habitat in Figure S1 of Matchett and Fleskes (2018), and summarizes areas of each flooded and dry waterbird habitat by planning basin, scenario, and month during the wintering period. These data support the following publication: Matchett EL, Fleskes JP. 2018. Waterbird habitat in California’s Central Valley basins under climate, urbanization, and water management scenarios. Journal of Fish and Wildlife Management. Online early. doi:10.3996/122016-JFWM-095

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 of available projected habitat area following completion of crop harvest and flooding of wetland and crop habitats during the season. 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). These data are used to support the following publication: Matchett EL, Fleskes JP (2017) Projected Impacts of Climate, Urbanization, Water Management, and Wetland Restoration on Waterbird Habitat in California’s Central Valley.

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 of waterbird habitats is summarized by scenario, habitat, and month in 1 metric (area of available habitat in km2).

To support coordinated conservation, wetland restoration, and climate adaptation planning, we have developed five future scenarios of the Central Valley's seasonally flooded cropland and wetland waterbird habitat based on the State’s most recent climate and land use projections (Wilson et al. 2021).The USGS Western Geographic Science Center and Point Blue Conservation Science modeled a Business-as-Usual scenario plus the four scenarios developed for the Central Valley Landscape Conservation Project, which diverged along two key themes: water availability and management for conservation. Scenarios varied by climate projection (hot and wet vs. warm and dry) and management priorities (wetland restoration rate, crop conversion rate, and prioritization of water for wetland and cropland habitats). Urbanization rates were the same for all scenarios. To model these scenarios, we integrated a hydrologic and water-use model (the Water Evaluation and Planning (WEAP) model, WEAP-CVwh, Matchett and Fleskes, 2017) with a land change model (the Land Use and Carbon Scenario Simulator, LUCAS, Wilson et al. 2020). The models produced annual maps of land use change and monthly maps of flooded habitat probability at 270-meter resolution, from 2011 to 2101 (Wilson et al. 2021). The scenarios were: Historical Business As Usual (HBAU) = historical water availability, historical management California Dreamin' (DREAM) = high water, good management Bad Business As Usual (BBAU) = high water, poor management Everyone Equally Miserable (EEM) = low water, good management Central Valley Dustbowl (DUST) = low water, poor management This data release contains three types of model output tabular summaries for four geographic areas: WEAP model zones, Sustainable Groundwater Management Act (SGMA) California Bulletin 118 groundwater sub-basins, Central Valley Joint Venture (CVJV) planning basins, and Central Valley regions. The datasets summarize 1) land use change for select land use/land cover classes, 2) area of likely flooded habitat, and 3) change in January flooded habitat area and its causes for the 5 future scenarios of managed waterbird habitat. The datasets were generated from the LUCAS model and the WEAP CVwh model as described in the parent manuscript. The full methods and results of this research are described in detail in the parent manuscript "Integrated modeling of climate and land change impacts on future dynamic wetland habitat – a case study from California’s Central Valley" (2021). These tabular summaries provide the underlying data behind the figures in the ESRI Story Map: Central Valley Water and Land Use Futures, https://wim.usgs.gov/geonarrative/centralvalleyfutures/ (Moritsch et al. 2021).
