This dataset is a digital elevation model (DEM) of the beach topography of Lake Superior at Minnesota Point, Duluth, Minnesota. The DEM has a 1-meter (m; 3.28084 foot [ft]) cell size and was created from a LAS (industry-standard binary format for storing large point clouds) dataset of terrestrial light detection and ranging (LiDAR) data with an average point spacing of 0.137 m (0.45 ft). LiDAR data were collected August 10, 2019 using a boat-mounted Optech ILRIS scanner and methodology similar to that described by Huizinga and Wagner (2019). References: Huizinga, R.J. and Wagner, D.M., 2019, Erosion monitoring along selected bank locations of the Coosa River in Alabama using terrestrial light detection and ranging...

Concerns about the influence of climate change on biota have emerged over the past decade, and responses in species populations and distribution patterns have already been documented (Parmesan 1996, Thomas and Lennon 1999). Current climates and communities will not simply migrate, but rather will re-form in novel ways over time (Fox 2007; Hunter et al. 1988; Williams and Jackson 2007). Due to the uncertainty of future climatic patterns and species responses, enduring features of the landscape (geophysical settings) are appropriate targets of assessment, planning, and conservation (Anderson and Ferree 2010, Beier and Brost 2010, Brost and Beier 2012; Hunter et al. 1988). Only recently have enduring features been...
We propose to support the revision and implementation of the South Atlantic Landscape Conservation Cooperative’s Conservation Blueprint by integrating its Ecosystem Indicators into a structured decision support system that makes explicit how the Indicators are interrelated and how these will respond to management and policy interventions aimed at improving the conservation status of the South Atlantic region. Our specific objectives are to (1) develop ecological production functions that predict theecological impacts of selected conservation actions relative to current conditions, and to propagate these impacts through other affected systems or functions; (2) codify protocols for updating and curating geospatial...
Version 2.0 Data Viewer for the South Atlantic Create a Version 2.0 Simple Viewer for the South Atlantic Conservation Blueprint that includes updates, additional data (category priorities, actions, justifications, ownership, and partner data), and dynamic charting of indicators and presentation of ecosystem and analysis unit aggregate indicator scores. Continue to refine and improve the South Atlantic Conservation Planning Atlas (salcc.databasin.org) Provide technical guidance and recommendations about how to structure data and future Viewer platforms to achieve specific functions for future versions of the Blueprint hosted within an interactive viewer and the South Atlantic Conservation Planning Atlas.

Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

Genetic, demographic, and environmental processes affect natural populations synergistically, and understanding their interplay is crucial for the conservation of biodiversity. Stream fishes in metapopulations are particularly sensitive to habitat fragmentation because persistence depends on dispersal and colonization of new habitat but dispersal is constrained to stream networks. Great Plains streams are increasingly fragmented by water diversion and climate change, threatening connectivity of fish populations in this ecosystem. We used seven microsatellite loci to describe population and landscape genetic patterns across 614 individuals from 12 remaining populations of Arkansas darter ( Etheostoma cragini) in...

Habitat fragmentation and flow regulation are significant factors related to the decline and extinction of freshwater biota. Pelagic-broadcast spawning cyprinids require moving water and some length of unfragmented stream to complete their life cycle. However, it is unknown how discharge and habitat features interact at multiple spatial scales to alter the transport of semi-buoyant fish eggs. Our objective was to assess the relationship between downstream drift of semi-buoyant egg surrogates (gellan beads) and discharge and habitat complexity. We quantified transport time of a known quantity of beads using 2–3 sampling devices at each of seven locations on the North Canadian and Canadian rivers. Transport time was...

Stream fragmentation alters the structure of aquatic communities on a global scale, generally through loss of native species. Among riverscapes in the Great Plains of North America, stream fragmentation and hydrologic alteration (flow regulation and dewatering) are implicated in the decline of native fish diversity. This study documents the spatio–temporal distribution of fish reproductive guilds in the fragmented Arkansas and Ninnescah rivers of south-central Kansas using retrospective analyses involving 63 years of fish community data. Pelagic-spawning fishes declined throughout the study area during 1950–2013, including Arkansas River shiner (Notropis girardi) last reported in 1983, plains minnow (Hybognathus...

Sediment accumulation in playa wetlands, such as those in the Rainwater Basin in south-central Nebraska, reduces the hydrologic functionality and alters the vegetative composition of the wetlands reducing their ability to provide forage and resting habitat for migratory birds. Most Rainwater Basin wetlands have intense agricultural production occuring within their watersheds that accelerate sediment accumulation within the wetland. This sediment accumulation reduced the abilty of the wetland to hold water which, in turn, allows invasive and upland plants to proliferate with the wetland footprint. Planting upland grassland buffers around wetlands reduces the sediment load entering the wetland reducing the need...

We propose to use long-term fish-population data from a relict reach of the Pecos River, New Mexico to assess population dynamics of imperiled prairie-river minnows, including Arkansas River shiner. Development of viable management strategies requires basic understanding of population ecology. Rigorous, quantitative ecological methods can be used to analyze continuous, long-term demographic data, but such data are rarely available for imperiled, non-game fishes. Data available for the Pecos River provide a unique opportunity to apply quantitative methods to prairie-river minnow conservation and management. Analyses proposed here would determine (1) whether population regulation is density dependent or flow-regime...

(Panorama with photograph 175, jwh00175) Henrys Lake, a shallow body of water, about 3 by 2 miles in diameter, and full of small, scattered islands, and the source of Henrys Fork. It is well stocked with most excellent trout. At this point are four remarkable passes through the range, Tyghee and Red Rock, on the east and west; Raynolds, or the Madison, on the north; and Henrys Lake, on the south.
