Today we explored the part of the Cityford burn that runs through Castlemilk. We started off with the Opal Water Survey with community scientist Jo Dempster. The full results for all 3 workshops can be found here. Since we last visited, the pond has become more overgrown, and much shallower, and we perhaps didn’t find as much biodiversity as we expected, or, infact, as much as Jo found on a previous survey. This was most likely due to the pond being shallower, and warmer, with much denser plantlife, allowing less light and oxygen to be absorbed into the water. We then made our way along the Cityford burn making underwater sound recordings on the way. Have are some sounds and photos from the day.
