The Army Corps of Engineers recently initiated a program to create and improve emergent sandbar habitat (hereafter ESH) throughout the upper Missouri River system. This program has resulted in creation of three sandbar complexes and implementation of vegetation control on existing sandbars in the Gavins Point reach during 2004 and 2005. In order to meet habitat acreage goals in the Biological Opinion, the Corps has developed extensive plans for numerous additional habitat creation and improvement projects throughout the upper Missouri River system. Given the momentum of current habitat creation and improvement projects and their associated costs, it is imperative that the capacity be available to quantify changes...

This data is a companion to the manuscript titled "Data integration reveals dynamic and systematic patterns of breeding habitat use by a threatened shorebird". Advances in both remote sensing and analytical tools for spatial data have allowed for the integration of dynamic processes into species distribution models. We developed a spatiotemporal model of breeding habitat use and density for a federally threatened shorebird (piping plover, Charadrius melodus) by integrating a 20-year (2000 – 2019) nesting dataset with opportunistic, volunteer collected (eBird), sightings. Piping plovers are an ideal candidate for dynamic habitat models because this species depends on habitat created and maintained by highly variable...
This task focuses on least tern use of natural, restored, and newly created habitats under the Emergent Sandbar Habitat program on the Gavins Point reach. It is designed to fully integrate with a concurrent study of piping plover productivity and foraging ecology for the same river reach. The goal of this task is to provide information on the breeding population and success of least terns and a rigorous scientific evaluation of the value of restored and created sandbar habitat for meeting productivity goals for interior least terns. [see Narratives for more information.]

This data set is part of a data release as a companion to a published manuscript titled "Low renesting propensity and reproductive success make renesting unproductive for the Piping Plover, Charadrius melodus." The Condor: Ornithological Applications. Upon reproductive failure, many bird species may make a secondary attempt at nesting. This data set includes four tabular digital data files representing values related to renesting propensity, renesting intervals, renest reproductive success, and nest survival of Piping Plovers (Charadrius melodus). We followed nests and unique breeding adults from 2014 - 2016 in the Northern Great Plains of the US. This included river and reservoir habitats present on the Missouri...
Federally listed least terns ( Sternula antillarum) and piping plovers ( Charadrius melodus) nest in spatially and temporally variable riverine, sandbar and shoreline habitats in the North American midcontinent. In a naturally functioning river system, sand is eroded, transported, and deposited by seasonally variable flows, creating and maintaining emergent sandbars. However, operation of dams on the Missouri River has attenuated peak spring flows, resulting in declines in abundance and quality of unvegetated sandbar habitats favored by nesting terns and plovers. The Missouri River Flood of 2011 was a historically and ecologically significant event in which summer flows exceeded all historical records for the post-dam...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
