Impact of disturbances and visitor management on the Little Ringed Plover Charadrius dubius and the Common Sandpiper Actitis hypoleucos. – As part of the «Swiss species recovery program for birds», we studied the literature about threats to the Little Ringed Plover and the Common Sandpiper and the effectiveness of protective measures. We focused on anthropogenic disturbances and how to reduce them. Disturbances can prevent both species from settling and can lead directly or indirectly to the loss of nests and chicks. Land side disturbances have a greater impact than water side disturbances. The most intense disturbances are caused by humans accessing gravel banks and by the presence of dogs. Measures for visitor management were implemented in numerous projects. These include information and awareness raising, prudent guidance, prohibition signs, closure of sensitive areas, and local rangers as advisors. Almost all measures showed positive effects and caused a reduction of disturbances. However, prohibition signs as sole measure, without simultaneous closure and personal presence, showed little effect. Protective measures have a positive effect on the breeding success of the Little Ringed Plover and are also considered to be effective for the Common Sandpiper. Effective protective measures include consistent visitor guidance distinguishing between protected and recreational zones and enforcing restrictions on the entry of protected zones. In the planning process of relevant projects such as river revitalization, these findings should be considered in advance for an effective visitor guidance concept, in order to mitigate or completely avoid potential conflicts.
