“…Future research should assess how industry practices and management of different site types influences the presence, absence, or amount of specific habitat features and how these finer scale habitat metrics affect habitat selection, use, and the various demographic consequences of such decisions by individual animals. Similar research (Sherfy et al 2012a, Farrell et al 2018 has been done at other off-river sites specifically managed for plovers and terns. This additional research in our system would provide a more complete understanding of how off-river sites in the LPRS affect or could affect local and regional populations.…”

“…The tern was federally delisted in February 2021 for various reasons, including population increases in parts of the species' range (86 FR 2564(86 FR -2581. Plovers and terns nest in mixed-species aggregations in the Platte River systems (Farrell et al 2018, Brown et al 2019. The Nebraska Game and Parks Commission and the Tern and Plover Conservation Partnership have monitored both species in the LPRS since the mid-1980s.…”

“…The lifespan of any one mine site is limited based on the amount of marketable and reclaimable aggregate available at the site. Sites are often converted to other uses once mining ceases, including recreation areas, lakeshore housing developments (Brown et al 2018), and in some cases directly to managed tern and plover nesting areas (Farrell et al 2018). The mechanical disturbance required to convert a sand and gravel mine into a lakeshore housing development usually extends the span of time in which a site provides habitat appropriate for nesting plovers and terns.…”

“…The presence and availability of sand and gravel mines and the concurrent decline of riverine habitats over time have resulted in a redistribution of the species within the Platte River system (Sidle et al 1992, Kirsch 1996). In fact, a majority of nesting in recent decades in the Platte River system by both species has occurred on off‐river sites and not on in‐channel riverine habitats (Brown et al 2017, 2018, Farrell et al 2018).…”

Decline of novel ecosystems used by endangered species: the case of piping plovers, least terns, and aggregate mines

et al. 2021

Sand and gravel mining creates novel ecosystems along the Platte, Loup, and Elkhorn rivers in Nebraska, USA. Piping plovers and least terns are state and/or federally threatened and endangered species, respectively, that nest and raise young at these sites and their derivatives. Despite hosting relatively large numbers of piping plovers and least terns for decades, an important question that has largely gone unaddressed is whether the industry that has produced these novel ecosystems is stable and will continue to produce habitat consistently in the future. We evaluated how the number, size, and spatial distribution of different site types hosting different numbers of nesting plovers and terns have changed over time and how current trends in the number of different site types will affect future habitat using a multi‐state modeling approach. Overall area and total number of sites declined during the period 1993–2020. More important, one site type, traditional mines, are being replaced by another site type, modern mines, which host lower numbers of nests of both species. The difference between these two site types is primarily how waste sand is stored. Traditional mines store waste sand in spoil piles or plumes along the edge of a lake created by the mining process, forming relatively large expanses of nesting habitat used by both species. Modern mines store waste sand in limited quantities along the edge of the lake but also in piles away from the lake. Traditional mines also differ from modern mines in that they are routinely converted to housing developments with intermediate transition sites that host the largest number of nests for brief periods. Based on the previous 28 yr of decline, traditional mines and their productive derivatives are projected to continue to decline, thereby further reducing overall nesting habitat. Piping plovers and least terns are expected to nest in our study sites for the foreseeable future, but overall numbers are expected to be smaller than what has been observed in previous decades. Local declines in our study area will have local and regional implications for the recovery and management of these two species of conservation concern.

Adaptive management (AM) is a rigorous approach to implementing, monitoring, and evaluating actions, so as to learn and adjust those actions. Existing AM projects are at risk from climate change, and current AM guidance does not provide adequate methods to deal with this risk. Climate change adaptation (CCA) is an approach to plan and implement actions to reduce risks from climate variability and climate change, and to exploit beneficial opportunities. AM projects could be made more resilient to extreme climate events by applying the principles and procedures of CCA. To test this idea, we analyze the effects of extreme climatic events on five existing AM projects focused on ecosystem restoration and species recovery, in the Russian, Trinity, Okanagan, Platte, and Missouri River Basins. We examine these five case studies together to generate insights on how integrating CCA principles and practices into their design and implementation could improve their sustainability, despite significant technical and institutional challenges, particularly at larger scales. Although climate change brings substantial risks to AM projects, it may also provide opportunities, including creating new habitats, increasing the ability to quickly test flow‐habitat hypotheses, stimulating improvements in watershed management and water conservation, expanding the use of real‐time tools for flow management, and catalyzing creative application of CCA principles and procedures.

Piping Plover population increase after Hurricane Sandy mediated by immigration and reproductive output

et al. 2020

Evaluating population-level responses to conservation action following large-scale disturbance can improve the efficacy of future habitat conservation measures. In October 2012, Hurricane Sandy storm surges cleared vegetation and opened inlets through the barrier islands, Fire Island and Westhampton Island, New York, creating Piping Plover (Charadrius melodus) habitat. Storm effects prompted an island-wide stabilization project, which had the potential to negatively affect novel Piping Plover habitat. Certain sections of Fire Island were designed to create and/or improve habitat (hereafter, restoration areas) to mitigate possible habitat loss or degradation. Since Piping Plovers in New York appear to be habitat-limited, we anticipated positive population growth following habitat creation. From 2013 to 2018, we captured and banded 152 adults and 353 chicks, and monitored 279 nests and 160 broods. We developed an integrated population model to assess demographic processes in response to hurricane created-habitat (2013–2018) and the creation of restoration areas (2015–2018). We observed positive population growth in 3 of 5 yr, and overall growth throughout the period (λ¯ = 1.13). Immigration and reproductive output were correlated with population growth (r = 0.92 [95% CI: 0.22 to 0.98] and 0.84 [95% CI: –0.47 to 0.95], respectively). Compared with the rest of the study area, restoration areas had higher chick survival, and lower nest survival and after second-year site fidelity. The result was population growth in restoration areas (λ¯= 1.14) similar to the whole study area. In the short term, restoration areas seemed to mimic natural Piping Plover habitat. Vegetation removal, an important process in renewing natural Piping Plover habitat, likely will be necessary to maintain habitat suitability. Efforts to increase immigration of new breeding adults into the system, and to improve reproductive output, primarily by habitat creation or maintenance, are likely to have the greatest local effect on population growth.
