River lifecycles & food chains on the Mawddach

As part of our Freshwater Pearl Mussel project in partnership with the Eryri National Park we have been out on a field visit with the amazing pupils from Ysgol Bro Hedd Wyn. Today they joined us on site to learn about river lifecycles and food chains and how to use invertebrates as water quality indicators.

The pupils were really enthusiastic and learnt how to identify Stonefly nymphs, Mayfly nymphs and other creepy crawlies. Pupils were also able to identify which invertebrates can only live in clean, well oxygenated rivers.

As a follow up session Ysgol Bro Hedd Wyn will be down on the riverbank measuring rainfall and helping us create Welsh resources for Invertebrate identification to share with other schools across North Wales.
