This is called natural reforestation.
Why is selective cutting bad?
“Selective logging, unless it is practiced at very low harvest intensities, can significantly reduce the biomass of a tropical forest for many decades, seriously diminishing aboveground carbon storage capacity, and create opportunities for weeds and vines to spread and slow down the ecological succession.”
Is selective cutting good?
When practiced correctly, selective cutting has the following benefits. Removes trees that are low quality while they are young. Removes some of the profitable mature growth. Allows more light to penetrate the upper story of growth.

What are the negative effects of clear cutting?
Clearcutting can destroy an area’s ecological integrity in a number of ways, including: the destruction of buffer zones which reduce the severity of flooding by absorbing and holding water; the immediate removal of forest canopy, which destroys the habitat for many rainforest-dependent insects and bacteria; the removal …
