Study area and locations of habitats used by wintering waterbirds.

<p>The Central Valley of California including major rivers, lakes, and reservoirs that are part of the surface water supply system and important waterbird habitats including managed wetlands, rice fields in the Sacramento Valley and Sacramento-San Joaquin River Delta (Delta) and flooded fields in the Tulare Lake (dry) bed (other corn not shown) existing in 2005.</p

Median and worst-year area and percent of existing wintering waterbird habitat for 17 scenarios.

<p>Median and worst-year area (km²) and percent (%) of existing wintering waterbird habitat projected to be available in the Central Valley of California during 2006–35, 2036–65 and 2066–99 for 17 scenarios comprised of various climate, urbanization, water management, and wetland restoration levels (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0169780#pone.0169780.t001" target="_blank">Table 1</a> for scenario descriptions). Existing habitat is the approximate area of waterbird habitat (3,183 km²) that existed in the Central Valley in 2005.</p

Scenarios modeled to evaluate projected impacts on habitats of wintering waterbirds.

<p>Climate and urbanization projections, water supply management options, and wetland restoration levels included in scenarios used to estimate annual water supplies and area of wintering waterbird habitats that could be supported with those water supplies in the Central Valley of California during 2006–2099.</p

Waterbird habitat projected for 17 scenarios, years 2006–2099.

<p>Area (km²) and proportion of existing (3,183 km² in 2005) wintering waterbird habitat projected to be available in the Central Valley of California during 2006–99 for 17 scenarios (A. 1–5, B. 6–9, C. 10–13, D. 14–17) comprised of various climate, urbanization, water management, and wetland restoration levels (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0169780#pone.0169780.t001" target="_blank">Table 1</a> for scenario descriptions).</p
