In the episode, John Craven and co-host Charlotte Smith visited the National Forest as it reached the milestone of planting its 10-millionth tree. John Craven reunited with former head of the National Forest, Susan Bell, who had been interviewed on the show in 1992. The clip from 1992 showed John Craven planting the first oak tree in the area and expressing ambitions for a sizable woodland, while Susan Bell expressed hopes to plant enough trees to cover 200 square miles, equivalent to the size of the Isle of Wight.
Susan Bell joked in the present episode that the goal of 30 million trees was an overestimate. The specific date the episode aired and who planted the 10-millionth tree during the episode have not been confirmed. It is also unknown how many trees have been planted to date beyond the milestone, what the current plans are for future tree planting, and what other guests or segments were featured.
Well, Susan, I've got a surprise for you. I've got a clip from that day 30 years ago when you and I talked about planting new trees in the forest.
