That is one of the issues we discussed with NGOs last week. Our sites often contain areas that have not been exploited yet. We would like to use those areas, that will eventually be used for extraction, as laboratories. We would like to do tests in order to determine whether or not it would be appropriate to reforest or rehabilitate a site, and which species would be best adapted to that area when we are trying to rehabilitate it in the future.
