Do artisanal fishers perceive declining migratory shorebird populations?

Area of Science:

• Ethno-ornithology
• Conservation Biology
• Ecology

Background:

• Ethno-ornithological research was conducted with artisanal fishers in northeast Brazil.
• Local ecological knowledge (LEK) of fishers regarding Nearctic shorebirds was investigated.

Purpose of the Study:

• To analyze the LEK of artisanal fishers concerning Nearctic shorebirds.
• To identify factors affecting shorebird populations based on local knowledge.
• To examine potential gender and age-related differences in LEK.

Main Methods:

• Study involved 240 artisanal fishermen using semi-structured and check-list interviews.
• Local ecological knowledge was assessed in relation to Nearctic shorebirds and population factors.
• Data collection occurred between August 2013 and October 2014.

Main Results:

• Men demonstrated greater knowledge of migratory birds and their habitats than women.
• Respondents attributed population changes to habitat disturbance, increased construction, and visitor numbers.
• Artisanal fishermen identified boat traffic and noise as primary threats to shorebirds, noting population declines.

Conclusions:

• Urbanization and tourism-driven landscape changes are primary causes of reduced migratory shorebird populations.
• Effective management of urbanization and tourism is crucial for shorebird conservation.
• Monitoring these factors is essential to improve migratory success and species conservation.
