Waterbirds breeding at wetlands in North Dakota forage mostly on aquatic invertebrates. Historically, productivity and abundance of aquatic invertebrates primarily was driven by inter-annual hydrological dynamics (i.e., wet-dry cycles). Wetland drying allows for nutrient cycling and a subsequent pulse of productivity when wet conditions return. However, abundance and quality of wetlands in North Dakota has declined due to landscape modifications, primarily agriculture. Consolidation drainage, a practice of draining less permanent wetlands into larger more permanent ones, is common in North Dakota and it increases connectivity and stabilizes water levels among remaining wetlands. For the effective management and...
Lake Sakakawea is a large (404,810 ac [163,800 ha]) reservoir located on the Missouri River in northwestern and central North Dakota, which recently was designated a high priority area for endangered species management. The reservoir shoreline is irregular, dissected, and consists of a wide variety of substrates, slopes, and aspects. The extent, distribution, and abundance of these features vary annually as lake elevation changes in response to precipitation, melt of Rocky Mountain snowpack, and releases from Garrison and Fort Peck dams. Water levels on Lake Sakakawea have declined over the past decade due to extended drought conditions; in 2005 they reached a record low since the initial flooding of the reservoir....

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...
We present two tabular data sets representing values to estimate apparent natal and adult survival and transition probabilities between breeding location states used in a multievent capture-mark-resight model for piping plover adults and hatch year birds in the Northern Great Plains from 2014-2019 focusing on four study areas: U.S. Alkali Wetlands (ALK), Lake Sakakawea (SAK), Garrison Reach of the Missouri River (GRR), and Lake Oahe (OAH). In addition, several covariates were included representing habitat and social variables.
In the Prairie Pothole Region (PPR) wetland plant, invertebrate, and waterbird productivity are primarily driven by water-level dynamics in response to climate cycles. Large proportions of wetlands in the PPR have been drained, often consolidating water from smaller to larger-interconnected wetlands. This project will examine whether large basins that receive inflow from consolidation drainage have reduced water-level dynamics in response to climate cycles than those in undrained landscapes, resulting in relatively stable wetlands that have lower densities of invertebrate forage for ducks and shorebirds. We will also include a sample of wetland historically used by piping plovers to assess the threat of consolidation...

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...
Prior to human alteration, the Platte River probably supported nesting least terns and piping plovers on mid-channel sandbars that were largely devoid of vegetation due to high spring flows. Modification of the river’s flow pattern has lowered the frequency and intensity of scouring events, resulting in vegetation encroachment and stabilization of sandbars. This has led to declining quality and abundance of unvegetated sand nesting habitat favored by least terns and piping plovers. Foraging habitat for piping plovers, consisting of sparsely vegetated moist or dry sand with high invertebrate production, has probably also declined in quality and abundance. However, least terns forage on small fish in side channels,...

This dataset describes features of 2941 duck nests that were found in the Prairie Pothole Region of North and South Dakota during 2002-2003. Nest features include estimated initiation date, incubation stage and status as active. The dataset accompanies a scientific journal article describing an evaluation of the density and success of duck nests in conservation fields in 36 study areas that were seeded with native or tame grasses. Field features in this dataset include seeding treatment, planted area, and area of grassland patch.
This dataset includes information from 59 prairie pothole wetlands in Minnesota, collected in 2019 and 2020. The data includes wetland characteristics (e.g., size, depth, plant biomass, and water quality), multiple fish metrics, and multiple amphipod metrics. The amphipod species include Gammarus lacustris and Hyalella azteca. There are 22 species of fish recorded.
This dataset provides wetland information for 49 semi-permanent wetlands in Minnesota, with target variables of amphipods, water quality variables, and aquatic macrophytes.

We present two tabular digital data files representing values related how the presence of hetero- and conspecifics influence nest and chick survival for two listed migratory species breeding on the Missouri River; piping plover (Charadrius melodus) and least tern (Sternula antillarum). We followed 2,507 piping plover nests, 3,251 uniquely banded piping plover chicks, 1,060 least tern nests, and 1,377 uniquely banded least tern chicks from 2007 - 2009, 2012- 2016 in the Northern Great Plains of the US. This included river and reservoir habitats present on the Missouri River in North and South Dakota. Not all study areas were studied in all years. The nest survival dataset includes values for use with the Shaffer...
Two tabular data sets representing values to examine survival estimates for piping plover nests and chicks in the Northern Great Plains from 2014-2016. We focused on four study areas: U.S. Alkali Wetlands, Lake Sakakawea, Garrison Reach of the Missouri River, and Lake Oahe spanning eastern Montana, North Dakota, and South Dakota. We followed nests to completion, either success or failure, and created capture histories for uniquely banded chicks.
These maps were developed to support an effort to understand the spatial characteristics of piping plover (Charadrius melodus) nesting habitats. The maps show the expected nesting habitat distributions and piping plover intensity between 2000 and 2021 in the U.S. Prairie Pothole Region.

We present one tabular data file to evaluate piping plover (Charadrius melodus) seasonal (breeding and nonbreeding) adult survival. These data were part of a study to examine adult (n = 3474) survival during 2012-2019 at breeding regions within the Northern Great Plains and nonbreeding regions in the Gulf and southern Atlantic Coasts of North America. This file includes USGS-funded data and not the full data used in the Larger Work. The seasonal adult survival data includes a multistate model encounter history.
We present a tabular data set representing values to estimate apparent hatch-year survival to adulthood and natal dispersal probabilities between two breeding groups of the Northern Great Plains piping plover (Charadrius melodus) used in a multievent capture-mark-resight model from 2014-2019. Focusing on the Northern Missouri River and U.S. Alkali Wetlands breeding groups. In addition, several covariates were included representing habitat and social variables.
We present two tabular data sets representing values to examine sources of variation in natal and breeding dispersal distances for piping plovers breeding in the Northern Great Plains from 2014-2019 focusing on four study areas: U.S. Alkali Wetlands, Lake Sakakawea, Garrison Reach of the Missouri River, and Lake Oahe. We included habitat variables, and conspecific densities in both datasets and include nest fates and mate fidelity in the breeding dispersal dataset.
We present a tabular data set representing values used to evaluate hypotheses of breeding habitat selection for immigrants and returning Northern Great Plains piping plovers (Charadrius melodus) from 2014 – 2019. The associated manuscript uses network analysis approach to evaluate five hypotheses of habitat selection. In this approach breeding locations were nodes and successive year breeding attempts form the edges (immigration) and self-loops (fidelity). Included in the dataset are covariates of habitat amount, conspecific density, and habitat quality, as well as other fields used in the analysis. In addition, we include descriptive breeding location-specific metrics from the network graphs.
Reliable ongoing monitoring of piping plover and least tern nests is crucial to assuring that protection efforts are contributing effectively and efficiently to recovery of these species. An annual inventory of the numbers, location, and productivity of breeding pairs will provide information on population trends, changes in distribution, recruitment, and other population parameters. Additionally, data collected at unsuccessful nests will provide insights to the causes of failures. These data will provide measures of overall progress towards recovery and facilitate identification of areas where additional management or protection needs to be applied. Monitoring to identify factors that may be limiting the species’...
