One of the most common trees in U.K. although it has been affected by Ash Dieback desease recently...

• Great as a building wood as it is strong and flexible (good for wood handles on hammers n axes).
• The sugary sap can be collected which is known as ‘Manna’.
• The king of woods for fires... Check out a poem called 'The FireWood Poem' it's a great one to teach the kids and explains each of the wood/trees in Britain for burning. https://allpoetry.com/The-Firewood-Poem
• Has many herbal properties = https://www.herbal-supplement-resource.com/european-ash.html

I'm sure there are many other uses too, but for me the primary one is for burning... good burning when green and dead...
