OPAL Survey

I've recently been working with a group to complete a clean air survey organised by OPAL (Open Air Laboratories). It involved measuring tree girths, counting fungal spots on sycamore leaves and identifying lichen on oak, ash and sycamore trees. The survey doesn't take long to complete and you could easily complete it in a local park or open area. What's more all the ID charts and materials you need are provided - a great teaching resource.
Why not take part - and let's see how clean the air in all areas of Britain is. There's lots of other surveys to complete too. Go on, try one...
