Conservation Value:

This species has a small global poplution once estimated to be in the thousands (7,000+) but surveys in 2021-22 indicate that the population may be less than 1,000.  A comprehensive survey of known breeding sites recorded just 264 individuals, while the following wintering area surveys recorded 300 individuals (including 55 juveniles). The species is the sole member of the family Pluvianellidae, increasing its conservation significance..

Threats:

Threats include reduced habitat quality of breeding areas due to sheep farming and the use of water bodies as watering holes; trampling of nests by cattle; disturbance by dogs and the use of all-terrain vehicles on the banks of lagoons. Indirect human impacts include the degradation and desertification of the Patagonian steppe due to overgrazing and climate change. Decreases in annual rainfall attributed to climate change may negatively affect reproductive success. Finally, there appears to be decreased quality of the wintering habitat near the city of Río Gallegos, with possible contamination from urban effluents and higher numbers of dogs.  An emerging threat is the installation of large wind farms in current and potential sites for plovers.

Actions & Results:

During the annual breeding season (November to February), "Plover guardians" survey and protect nests at key sites for the species, subject to accessibility, weather conditions, and presence of the species.

By December 12 pairs were located at the Buenos Aires Lake Plateau.  

In addition to the presence of guardians, camera traps were placed at these sites to assist in the collection of information needed to better understand threats.  To combat threats experimental "preadtor exclosures" made of wire fence with openings large enough to allow passage of plovers through the mesh are placed over some nests and this successfully protects eggs from predators and trampling by sheep, livestock, or ATVs. 

As part of further research to better understand the species' movements, some adults and chicks are banded and tagged with Lotek Solar trackers that emit signals every 10 days.
