Help build up a picture of the UK's natural environment, learn new skills and 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 native and invasive invertebrates, and the importance of habitats for wildlife. We provide easy-to-follow survey instructions, straightforward ID guides and a variety of other resources to help you explore your local environment.
We make your survey data openly available to scientists to help build up a picture of the UK's natural environment.
