QRAAT sites at the Quail Ridge Reserve

The Quail Ridge Automated Animal Tracking System (QRAAT) at the Quail Ridge Reserve in Napa County, California is designed to be the most advanced automated system capable of tracking small and medium-sized animals at an appropriately fine resolution. QRAAT is the result of an NRS initiative in collaboration with wireless network researchers, antenna engineers, dataflow specialists, visualization and graphics developers, and biologists interested in animal movements, physiology, and behavior.

Key features of the system include:

  • Programmable estimation of positions to capture rapid, small movements – e.g. produces a position per second for standard transmitters
  • Capacity to monitor multiple individuals of different species to allow application of social network analysis to examine interactions and collective behavior
  • Ability to detect physiological parameters, such as heart rate and temperature, and ambient sound simultaneously with position, enabling correlation of stimulus and response
  • Sufficiently large range for detection of interactions among species across multiple trophic levels
  • Use of small transmitters to enable tracking of small mammals
  • Automated processing and visualization interfaces designed for end users
  • Software is open-source, modular design facilitating replication at other sites around the world
