More than 400 people have already signed up for the forthcoming OPAL tree health survey just one week after registration opened.
The survey will give people the chance to learn more about the trees in their local environment, and the pests and diseases that can affect them.
There is still plenty of time to register for a pack for you, your school or your community group.
So sign up today to be among the first to take part when the survey launches this spring.
