Monitoring the abundance diversity and distribution of birds in wetlands is used to track the effect of changes in hydrology and water quality related to human activities, flow regulation and climate change.
Automated Recording Units (ARU) are deployed annually in the spring prior to the breeding season, to detect presence and estimate the relative abundance of birds and amphibians. The ARU’s are programmed to take a 10-minute recording at dusk and dawn.
Randomly selected recordings are professionally transcribed to identify species and abundance.
