Joint Oireachtas Committee on Agriculture, Food and the Marine

Forest Policy and Strategy (Resumed): Discussion

Mr. Mark Carlin:

Yes, it is a challenge and Coillte is trying to achieve the best carbon balance. If the right thing is to remove a forest and to rewet, it is negative in the short term from a carbon point of view. We lose the crop that sequesters the CO2 plus there is methane emission as the bog is rewetted, which is worse than CO2. What happens then is that the bog is stabilised. It stops emitting carbon and in the very long term, in 50 to 60 to 70 years, it starts to absorb CO2 again. It is a mix of doing that plus rewetting. The Deputy referred to 30,000 ha with trees removed. We would not say 30,000 ha would have trees removed for rewetting. It is a combination of rewetting and rewilding. Where we are rewilding, we will be coming back in with another forest again.
