Forest management in the Eastern Amazon involves harvesting trees in a sustainable way. A study looked at how this affects the growth of new trees. They found that the harvesting method used did not harm the growth of the trees. In fact, it actually helped more trees to grow in the long run. They also tested planting new trees in the areas where trees were harvested, which helped to protect rare tree species. However, these planting methods were not profitable under current conditions in the Amazon. Overall, the study shows that sustainable forest management can help trees to grow and protect rare species, even though it may not always be profitable.
