The AMIBIO project aims to construct and deploy autonomous multi sensor monitoring stations and to automatically analyze their transmitted measurements for long-term monitoring of biodiversity activity trends in the region of Hymettus.
The project will deploy a prototype hardware system in a mid to low forest canopy and other relevant habitats, such as semi-open scrublands and around wetlands that will gather and transmit recordings of audio and environmental variables to a central station.
Acoustic monitoring stations, which are non-intrusive and cost-effective compared to human expeditions, will be set up for systematic seasonal and longitudinal long-term environmental monitoring that will allow the automatic inventory and examination of the biological diversity of a region. The monitoring stations are small (< 0.5 m3) and powered by solar panels. Their function is to record audio and climate data and to transmit these measurements to a distant central station for automatic statistical analysis. The central station will perform all signal processing tasks and carries out the acoustic survey of a designated area.
The expected outcomes of the AMIBIO project are related to the development and deployment of autonomous remote stations and the analysis of acquired data:
- Biodiversity assessment and inventorying of an area. Visual surveys and human involvement typically give good spatial coverage, but they are expensive and biased towards good weather conditions. Acoustic monitoring, on the other hand, gives good temporal coverage of a single area, is cost efficient and facilitates the indirect interpretation of the resulting data.
- Estimation of the density of animals in the monitored areas. The global environmental crisis is manifested, among others, in the declining diversity and deteriorating status of animal populations. Therefore, long-term acoustic monitoring of certain species and their population trends serves as indicator of environmental health. The species and their density can be used for drawing conclusions on the pollution levels, destruction of the habitat and migration of birds.
- Monitoring and alarming about the presence or absence of rare and threatened species in inaccessible areas as well as of night-migrating birds. Animal population densities can be estimated from the frequency, intensity, and spatial distribution of their sounds, which subsequently can be related to the status of biodiversity.
- Estimation of the health of certain species from their vocalizations.
- Monitoring and alarming of specific atypical sound events such as these related to potentially hazardous human activities (e.g., gun shoots and felling of trees) and report to the corresponding authorities for an emergency situation.
- 24/7 monitoring for danger and crisis events. Audio and climate data will be used to detect and monitor natural calamity and human induced disasters (fires, storms).
