Oak Day 2026
Oak Day is an Action Oak initiated, targeted day of awareness raising for Oak Trees native to the UK, which falls within National Tree Week.
A prominent tree across history for the UK’s flora, fauna & human population, the benefits of our native oak trees have been felt far and wide, from the biodiversity they support to the livelihoods of the people who rely on them.
What would the loss of such a prominent tree mean for the species and people who rely on them?
This question isn’t just hypothetical, the threat to oak trees has grown considerably. 300 species rely on our oaks, losing them would mean losing 301!
With existing and emerging pests & diseases, and the growing climate emergency, the time for action is now.
Oak Day 2026
Oak Day 2026 is part of National Tree Week which is Friday 27th November - Saturday 5th December 2026. This year Oak Day will be on Thursday 3rd December.
