Shelterwood cutting

A shelterwood establishment cut, eastern white pine
Undesired balsam fir preventing desired white pine regeneration
A partial overstory removal cutting in eastern white pine. Compare the amount of light reaching the seedlings to that in the establishment cut.

Shelterwood cutting refers to a progression of forest cuttings leading to the establishment of a new generation of seedlings of a particular species or group of species without planting. This silvicultural system is normally implemented in forests that are considered mature, often after several thinnings. The desired species are usually long-lived and their seedlings would naturally tend to start under partial shade. The shelterwood system gives enough light for the desired species to establish without giving enough light for the weeds that are adapted to full sun. Once the desired species is established, subsequent cuttings give the new seedlings more light and the growing space is fully passed to the new generation.
