Thank you for these ID sites, especially the Hainault Forest one.
We are blessed that our school grounds have lots of land and trees already, and we are now a Forest School and an Eco School. The children have set up a nature area for the wildlife with lots of bird tables which they designed and built themselves. I had a free hedgerow pack for them from the woodland trust, they are going to study the different hedgerow trees, and what types of wildlife they support, so your links are brilliant for them to use.
Here's the link if you want trees for your schools...you can order the Spring pack after October 9th.
