Anna Forbes from ARK told the children that although it is better than it used to be, there is still dog mess on the Stonebridge Wild River Reserve. “If a dog poos on the path or off it, owners and dog walkers should ‘Bag it and Bin it.’ There are five bins (sponsored by Drove Vets) on the reserve so there is no excuse not to use them.”

After donning waders (the water levels are currently high) the children collected samples from the river and wetland area. With help from ARK volunteer, Glyn Horn and Anna, they were shown how to identify six specific invertebrates that don’t tolerate poor water quality. They also measured the flow of the river and compared nitrate and phosphate levels in the river and the wetlands.
Anna explained that the data collected by the children would contribute to ARK’s data and freshwater watch. “It is interesting and useful for you but it also contributes to data that is being used all over the world.”
Beckie Ambrosini, Year 5 teacher at Marlborough St. Mary’s, said, “The whole morning has been absolutely excellent. The more outdoor, hands-on learning the pupils can do the better.”
