Barrier Tracker V2

AMBER Barrier Tracker is a free citizen science app for mapping and recording river barriers and other obstructions that affect river connectivity.

Rivers are essential ecosystems, but they are often fragmented by structures that interrupt the natural movement of water, sediments and aquatic organisms. Many of these barriers are still unmapped or poorly documented. By recording them in the field, you can help scientists and river professionals build a better understanding of river fragmentation.

With AMBER Barrier Tracker, you can:

• Map river barriers in the field using your device's GPS and interactive maps.
• Record lateral and longitudinal barriers, providing a more complete picture of river fragmentation.
• Collect detailed observations about barriers and their characteristics.
• Improve data quality through location validation and structured field observations.
• Contribute to citizen science by sharing observations that can support freshwater research and river restoration.

Designed for field observations

The app has been designed to make river barrier surveys accessible to a wide range of users, from river enthusiasts and volunteers to researchers and environmental professionals.

Improved geolocation and map visualisation help you locate and document barriers directly in the field. Structured questions guide you through the observation process, while Expert Mode provides experienced users with additional questions and more detailed classification options.

Help improve knowledge of river connectivity

Every observation can help fill gaps in existing barrier inventories. By combining observations collected by citizens with existing scientific and environmental datasets, AMBER contributes to a more comprehensive understanding of river fragmentation.

Better knowledge of where barriers are located and how they affect rivers can support research, monitoring, conservation and river restoration efforts.

A collaborative citizen science project

AMBER Barrier Tracker is built around collaboration between citizens, researchers, river professionals and organisations working to better understand and restore freshwater ecosystems.

Your observations become part of a growing body of information about river barriers. By contributing data from the field, you can help researchers identify knowledge gaps and improve our understanding of river connectivity.
