Tree O'Clock events in Wales
The first will be for the most number of trees planted in one hour between 11am - 12 noon on Sat, 5th December and the second record for multiple locations.
It's all free - all you have to do is turn up and lend a hand.
For a limited time only, BBC Breathing Places has joined forces with Plant for Life to give away thousands of trees to get people involved in the world record event known as Tree O'Clock.

If you're looking for an event to attend in South Wales then the Gendros community centre could be the one for you.
They're aiming is to plant over 300 trees on 5 December so wear suitable clothing and be prepared for some digging!
Half the trees will be planted as a hedge on a bank and the other half within a fenced each helping to defining the edge of the "wild play space" and providing food and shelter for the local wildlife.
The address is Gendros Road East, Gendros in Swansea.
