Andrew is tree hunting with Rob McBride, a self proclaimed 'Tree Hunter'. Rob, and members of the public, are searching Wales for the largest Oak they can find as well as other ancient trees, which will then be recorded on a database by The Woodland Trust. If you think you have one in your back garden to add to the list, then head to their website. Andrew is also lending a hand planting new trees, using 'Pollinator Packs' from The Woodland Trust.
