Underwood Hills Environment Citizen Science team conducted the quarterly macro-invertebrate sample of Underwood Hills Park stream Sunday morning.
Encouraging signs of life were found, including Crane-fly larva, lung snails and freshwater crays, though the stream only rates a 'fair' for ecological health.
Species very sensitive to pollutants were completely absent, probably due to the runoff from suburban backyards, known to commonly have high amounts of pesticides, fertilizers and pet feces. Last month's Bacterial tests revealed still very high levels of e-coli- persistent throughout summer, even though temperatures have dropped. Data can be seen here.
