Today, along with a plethora of marine fossils strewn across the Great Plains, vestiges of this ancient sea include a handful of inland saline wetland areas, with groundwater pickled by underground salt deposits from evaporated seawater."},{"acf_fc_layout":"image","image":679042,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Wetlands are important for wildlife habitat, water quality, flood protection, erosion control, recreation, and aesthetic value. Inland saline watersheds have additional conservation concerns due to their environmentally unique ecosystems and the many endangered species that rely on them.\r\n\r\nSome of these inland saline wetlands lie in eastern Nebraska\u2019s Little Salt Creek watershed near the state\u2019s capital city of Lincoln, about 1,000 miles (1,609 kilometers) from the nearest ocean. They are home to many unique or endangered plant and insect species, such as the federally protected Salt Creek tiger beetle. The wetlands cover only about 4,000 acres (approximately 16 square kilometers)\u2014down from about 20,000 acres (about 81 square kilometers) prior to European settlement\u2014and much of the habitat has been degraded or lost due to factors such as urban development, levee construction, and stream-channel straightening.\r\n\r\nMany of this area\u2019s current, former, and potential saline wetland areas are now being protected and restored with help from ArcGIS technology. By applying ArcGIS Pro, the Arc Hydro Wetland Identification Model (WIM), and several ArcGIS apps, water resources engineering consulting firm The Flatwater Group (TFG)\u2014together with wetland managers from the Saline Wetlands Conservation Partnership\u2014developed 120 ecosystem restoration project plans for this area, known as Nebraska\u2019s eastern saline wetlands."},{"acf_fc_layout":"content","content":"<h2>ArcGIS StoryMaps Story Helps Launch a Watershed Plan<\/h2>\r\nFormed in 2003, the Saline Wetlands Conservation Partnership includes the City of Lincoln, the Lower Platte South Natural Resources District, the Nebraska Game and Parks Commission, and Pheasants Forever. With funding from the Natural Resources Conservation Service\u2019s Watershed and Flood Prevention Operations program, TFG and the partnership developed an environmental assessment as well as restoration project plans that will address erosion, control sediment, stabilize streams, and more.\r\n\r\nTo raise awareness and educate the public about Nebraska\u2019s eastern saline wetlands, their financial value, and their importance to local ecosystems, the partnership held a virtual public meeting in 2021 that featured <a href=\"https:\/\/storymaps.arcgis.com\/stories\/743366627da0480593ed038fba3a6672\">an ArcGIS StoryMaps story<\/a> and an interactive app made with ArcGIS Web AppBuilder. The meeting\u2019s presentation outlined the planned conservation approach and the need for ecosystem restoration and protection in Nebraska\u2019s Little Salt Creek watershed. The story and the app also facilitated required functions for the project, such as soliciting public comments."},{"acf_fc_layout":"image","image":679052,"image_position":"left","orientation":"vertical","hyperlink":""},{"acf_fc_layout":"content","content":"<h2>From Data Inputs to Spatial Analysis<\/h2>\r\nThe partnership and TFG evaluated the Little Salt Creek watershed\u2019s saline wetlands and habitats using ArcGIS Pro, Arc Hydro WIM, and GIS datasets. They considered vegetation, soil, and hydrology\u2014the three factors that can determine whether an area is a wetland or has the potential to become one.\r\n\r\nFor vegetation, TFG engineers and scientists enhanced data from the US Geological Survey\u2019s 2011 National Land Cover Database with saline wetland categorization maps. For soils, they referred to the Natural Resources Conservation Service\u2019s Soil Survey Geographic Database. For hydrology, they used the Arc Hydro WIM, which predicts wetland locations using lidar elevation data and machine learning, along with a surface water raster to develop a depth-to-water index and predict specific areas\u2019 suitability for restoration or other actions.\r\n\r\nWhen combined using a raster matrix, the vegetation, soils, and hydrology data helped generate saline wetlands restoration suitability rankings. This included a map that facilitated a first-of-its-kind functional assessment for saline wetlands\u2014something that\u2019s needed to do a federally required economic cost-benefit analysis.\r\n\r\nAs these restoration projects proceed, planned operations and maintenance phases will employ the same ArcGIS tools to assess the projects\u2019 benefits. Drone photography, multispectral imagery, and lidar data will be used alongside ArcGIS software to enhance monitoring and track site changes, such as the boundaries of groups of native and invasive vegetation. After implementation, the projects will provide the next chapter in the protection and restoration of Nebraska\u2019s eastern saline wetlands."}],"references":null},"yoast_head":"<!-- This site is
