The company establishes permanent forests to mitigate climate change through carbon credits. Locals say the company already has one farm in the Waitaki region which is already showing adverse environmental affects. Natural resources engineer at environmental consultancy group Irricon Keri Johnston, who spoke at the meeting, said the community is not against forestry but just wants a better understanding of what is going on. "The Kakanui River is already considered to be water short - so the presence of forestry over such a large area in the headwaters of the catchment will impact the amount of water which makes its way into the river."
