There are 3 deciduous oaks that you are likely to see in the wild. They are the English Oak, the Sessile Oak and the Turkey Oak. In winter you can’t identify them from a distance but if you look closely at their buds and old acorn cups you should be able to tell one from the other. All the photos shown in this post are taken from the Tree Guide UK app.
