Age 11 · Biology
A forest is divided into separate plots. Each year only one plot is cut, so the others have decades to grow back before they are cut again.

In the picture
- Freshly cut plot: bare soil and low cut stumps
- Regrowing plot: young trees taller than saplings
- Untouched canopy plot: dense tall trees left uncut
Examples
- A woodlot where one strip is cut each winter while the other strips keep growing.
- A community forest that harvests a different block every ten years.
Key takeaways
- Cutting only one plot at a time gives the other plots time to regrow.
- When the same plot is cut again, it has already grown back into mature forest.
