National citizen science surveys – get involved


Help OPAL scientists with valuable research, learn new skills, have fun

OPAL is running surveys across the UK to learn more about the state of our environment, and we’d like everyone to get involved.

The surveys explore the health of our soils and trees, the quality of our air and water, the distribution of invertebrates, and the importance of hedges. We provide easy-to-follow survey instructions, straightforward ID guides and support from our community scientists across the UK.

Your contribution is important in helping scientists build up a picture of the UK's natural environment.
