Measuring potential negative effects of traditional harvesting practices on waterbirds: a case study with migrating curlews
Abstract Because of potential conflicts between commercial and conservation interests, one challenge in coastal‐area management is how to regulate harvesting practices in coastal areas without adversely affecting the survival of migratory waterbirds. In most Spanish intertidal areas of importance fo...

The presence of harvesters had a significant effect on foraging activity (no harvesting: 86.47±1.01%; harvesting: 82.70±1.00%). However, the absence of significant differences in all other foraging variables, between days with and without harvesting, indicated that curlews were able to compensate for the impact of harvesters on their foraging activity. We recommend, as a point of departure, that intertidal coastal managers of this Spanish site and similar areas of importance for shorebirds limit the harvesting load to <0.56 persons per 10 ha −1 at least during autumn migration.
