The Conservative Party has said it will plant 30 million trees a year by 2025 if it wins the general election - as the Liberal Democrats pledged to plant twice as many trees in the same period.
The Tories' £640m fund would be used to plant trees and restore peatland.
Labour dismissed the scheme and said the prime minister had an "atrocious environmental record".
The Lib Dems would plant 60 million trees a year across the UK by 2025, leader Jo Swinson said.
What does Jeremy Corbyn have to offer in the tree planting competition? I suggest he doubles the Lib Dem offer and goes for 120 million. Then it is over to the Greens who must think in terms of 240 million a year at least.
