Satellite Technology for Wildlife Welfare Monitoring

Satellite tracking and remote sensing technologies are transforming our ability to monitor wildlife welfare at landscape and global scales, providing data impossible to collect by traditional means.

Key Facts

GPS and Argos satellite tags now weigh under 1g, enabling tracking of small birds including warblers across entire migration routes
Satellite tracking revealed that Arctic terns migrate from pole to pole annually - over 70,000 km
Remote sensing satellites can map habitat loss and fragmentation affecting wildlife welfare at continental scales
Accelerometer tags can measure animal movement, flight patterns and behaviour without direct observation
Sea surface temperature satellites enable real-time monitoring of marine mammal prey distribution changes
Tag welfare standards specify maximum tag weight as 3-5% of body weight to minimise welfare impact of the devices themselves
Data from satellite-tracked animals has identified previously unknown critical stopover sites for migratory species

Welfare Considerations

Satellite monitoring technology creates a tension between the welfare cost of attaching tracking devices and the welfare benefit of the knowledge gained. Minimising tag weight, ensuring attachment does not restrict natural behaviour, and limiting capture stress during deployment are essential welfare considerations. The information generated - identifying critical habitats, migration bottlenecks, and population decline causes - enables conservation interventions that benefit far more animals than are affected by the tracking process itself.

What You Can Do
