Definition
Noun: A forest or stand of trees that has regrown naturally after the original, primary forest was removed or destroyed, typically by human activities like logging or by natural disturbances like fire.
Usage
This term is used specifically in forestry, ecology, and environmental science to describe a regenerated forest area. It implies the land previously supported a mature forest that was cleared.
Examples
- The hiking trail winds through a dense area of second growth, mostly young pines and birches.

- After the wildfire, the valley is slowly recovering with a mix of shrubs and second growth.
Advanced Usage
- Ecological Context: "Second growth" often refers to forests that are in a secondary stage of ecological succession. These forests are typically younger, have less biodiversity, and contain smaller-diameter trees compared to primary (old-growth) forests.
- Economic Context: In timber production, "second-growth timber" is harvested from these regenerated forests.
