Trees

Lord Jones of Cheltenham Excerpts

Tuesday 23rd February 2021 Lords Chamber

[Lord Goldsmith of Richmond Park (Con) [V]]

As I have said, the default position and the Government’s priority when it comes to deploying the funds put aside for this programme will be in favour of mixed woodlands—either planted or as a result of natural colonisation—in the appropriate areas. We want that diversity back. In the case of some of these appalling tree diseases which threaten iconic species—ash dieback, for instance—we have specific programmes. We know that a large number of ash trees will become infected, but not all of them will die. We expect that 1% to 5% will show tolerance, so we are funding research into future breeding programmes of tolerant trees. We are conducting, I believe, the world’s largest screening trials and will plant the first of the tolerant trees later this year.

[Lord Jones of Cheltenham (LD) [V]]

My Lords, a young plantation is an emitter of CO₂ for the first few years so will not help in achieving a short-term target. How long does the Minister think it will take for net carbon reduction to occur?

[Lord Goldsmith of Richmond Park (Con) [V]]

The noble Lord is right that the value of trees to carbon sequestration does not begin immediately. It can take up to seven years, depending on the tree variety and the quality of the land. But our commitment to planting at least 30,000 hectares a year, or allowing the natural regeneration of up to 30,000 hectares a year, across the UK by 2025 is based on advice from the committee on climate change, which recommended that figure as a minimum to help us to reach our net-zero emissions target by 2050.
