Forested wetlands and associated bottomland hardwoods represent a unique and imperiled habitat in the region that supports birds and many other wildlife species. Maintaining the structure and integrity of these forested wetlands has conservation implications that extend beyond the West Gulf Coastal Plain/Ouachitas region due to the ecosystem’s importance for birds migrating to and from Mexico, the West Indies, and Central and South America. This indicator also promotes consistency with the forest management and protection priorities of the Lower Mississippi Valley Joint Venture.<p style='background-color:rgb(255, 255, 255); border:0px solid currentcolor; box-sizing:border-box; color:rgb(74, 74, 74); font-family:"Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:12pt 0in 4pt; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'>Input Data<div style='background-color:rgb(255, 255, 255); border:0px solid currentcolor; box-sizing:border-box; color:rgb(74, 74, 74); font-family:"Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; line-height:1.5; margin:0in; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'><ul><li><a style='border:0px solid currentcolor; box-sizing:border-box; color:rgb(0, 97, 155); font-family:inherit; line-height:1.5; text-decoration:none;' target='_blank' href='https://www.lmvjv.org/wgcpo-forested-wetland-decision-support-model' rel='nofollow ugc noopener noreferrer'>WGCPO Forested Wetland Decision Support Model</a>; detailed description of methods is available under “Decision support model” in the <a style='border:0px solid currentcolor; box-sizing:border-box; color:rgb(0, 97, 155); font-family:inherit; line-height:1.5; text-decoration:none;' target='_blank' href='https://static1.squarespace.com/static/5bb3865d2727be6f94acf2fc/t/5bfc99b221c67c2cdd60ab54/1543281078237/WGCPO_BLH_Riparian_Plan_Oct2017.pdf' rel='nofollow ugc noopener noreferrer'>West Gulf Coastal Plain/Ouachitas Forested Wetland Plan, Version 1.0</a> </li></ul></div><p style='background-color:rgb(255, 255, 255); border:0px solid currentcolor; box-sizing:border-box; color:rgb(74, 74, 74); font-family:"Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:0in 0in 0in 0.5in; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'>This decision support model first characterized the landscape that was available to each forested wetland bird umbrella species for breeding. It identified landscapes with enough potentially suitable habitat to support a minimum viable population based on the amount of woody wetland landcover, minimum viable population size and area requirements, and natal dispersal distance. Then, it prioritized that potential breeding landscape based on each species’ unique habitat needs: distance to water, percent forest cover, flood tolerance and flood preference, and presence of bald cypress-tupelo floodplain forest. Lastly, it combined each species-specific habitat suitability model into the final composite index used in this indicator.<p style='background-color:rgb(255, 255, 255); border:0px solid currentcolor; box-sizing:border-box; color:rgb(74, 74, 74); font-family:"Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:0in; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'> <ul><li><a style='border:0px solid currentcolor; box-sizing:border-box; color:rgb(0, 97, 155); font-family:inherit; line-height:1.5; text-decoration:none;' target='_blank' href='https://secas-fws.hub.arcgis.com/maps/8bde4161a8af4ab9ad8341ef79d9d307/about' rel='nofollow ugc noopener noreferrer'>Base Blueprint 2022 extent</a></li><li><a style='border:0px solid currentcolor; box-sizing:border-box; color:rgb(0, 97, 155); font-family:inherit; line-height:1.5; text-decoration:none;' target='_blank' href='https://secas-fws.hub.arcgis.com/maps/0b3e3940763a4e3aae7647b0fe4c31e4/about' rel='nofollow ugc noopener noreferrer'>Southeast Blueprint 2023 extent</a></li></ul><p style='background-color:rgb(255, 255, 255); border:0px solid currentcolor; box-sizing:border-box; color:rgb(74, 74, 74); font-family:"Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:12pt 0in 4pt; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'>Mapping Steps <ul><li>Reproject the WGCPO Forested Wetland Decision Support Model source data to NAD 1983 Contiguous USA Albers (EPSG 5070).</li><li>Reclassify the source data as seen in the legend below.
