Little Ringed Plover
In Switzerland, the Little Ringed Plover is considered to be endangered, with 90–120 breeding pairs and an uneven distribution.
The species is exposed to many threats in natural and newly colonised habitats, but can be conserved by revitalising rivers and protecting breeding sites from disturbance.

Little Ringed Plover
In Switzerland, the Little Ringed Plover is considered to be endangered, with 90–120 breeding pairs and an uneven distribution.
The species is exposed to many threats in natural and newly colonised habitats, but can be conserved by revitalising rivers and protecting breeding sites from disturbance.
In Switzerland, breeding habitats suitable for the Little Ringed Plover are rare, as natural river dynamics have been lost due to watercourse straightening and the construction of hydroelectric power plants. Although the species can also use alternative habitats, these too are scarce and often suitable only on a temporary basis.
- Loss of natural watercourse dynamics.
- In natural habitats: disturbance caused by visitors and sudden changes in water levels (flooding) lead to breeding losses.
- In alternative habitats (e.g. gravel pits), site operations pose a risk.
- Suitable resting or wintering areas are relatively limited, and here, too, human pressure leads to frequent disturbance.
- Continue population monitoring, especially in areas with revitalisation projects.
- Enhanced monitoring at alternative sites: it is particularly important to identify nesting sites as early as possible, especially in gravel pits and on construction sites, so that protection measures can be taken.
- Develop large-scale river revitalisation projects, including visitor management.
- Safeguard natural hydrological and sedimentary dynamics in rivers to create pioneer habitats.
- In alternative habitats: improve communication with stakeholders (especially gravel pit operators) so that breeding sites are protected.
- Study the importance of reproductive success, survival and inward and outward migration in population trends at natural breeding sites and in alternative habitats.
- Determine the impact of disturbance and human activity on the species in the various habitats.
- Experience from several improvement projects shows that the species responds very well to the revitalisation measures taken to support it and that the number of pairs breeding in natural habitats is increasing.
- The species can survive only if sufficient habitats are available. Further efforts are therefore needed to ensure the availability of sufficient natural breeding sites, as well as alternative habitats.
Disturbance by humans or dogs can adversely affect habitats and lead to e.g. breeding losses. This can be prevented through information, barriers, rules or bans.
Renaturalisation of watercourses, mainly by widening the riverbed, and return to natural hydrological and sedimentary dynamics.
