Selective Logging – The cutting out of trees with are mature or inferior to encourage the growth of the remaining trees in a forest or wood
Selective has the word "select" in it which helps to remind you that selective logging is selecting only certain trees to chop down. See below the difference between deforestation (non-selective) and selective logging:
Where selective logging is accompanied by replanting, the rainforest canopy can be preserved. It means the forest can recover as the younger trees gain more space and sunlight to grow. Properly controlled logging ensures that for every tree that is logged, another is planted.
