I will jump in.
There is always something. We have been doing research on reforestation now for just about 50 years. That's not a long history of scientific knowledge. I would bring in here the need to know more about the properties of the trees that we are planting. That's something you have to look ahead at for the future, and no genomics have been input. It's improving quite a lot, but we have to go much further to know exactly what to plant and what type of tree that will give us. We need to have a good indication about the quality of the fibre and the strength that future forests will bring to the industry.
I think there's a wide area to continue to work on, to bring more information on those and then identify that the trees we're planting are the good ones for our vision of the future of the industry.
