Macroinvertebrates are an important part of the ecology of the region’s rivers and are often used as an indicator of overall habitat condition and water quality based on their individual tolerances for parameters like pollution, dissolved oxygen and temperature and their tendency to move relatively short distances during the aquatic phase of their life cycles. The Ipswich River Watershed Association began collecting data at a number of sites in the Ipswich River Watershed since the late 1990s and has been sampling the same sites annually since 2011. We will compile analyze these data and add additional sampling sites throughout the PIE-Rivers region to supplement the coverage in the Ipswich.
