A silvicultural system where mature trees of desired species are retained in a harvested area to provide a source of seed for natural regeneration. These selected trees, known as seed trees, are strategically left standing to disperse seeds across the cut area, promoting the establishment of a new forest stand. The method contrasts with clearcutting, which removes all or almost all trees. An example would be leaving five to ten well-spaced oak trees per acre after harvesting surrounding timber, allowing acorns to germinate and grow into a new oak forest.
This regeneration method offers several advantages. It can reduce the need for artificial planting, lowering costs and preserving the genetic diversity of the original forest. It also provides some immediate habitat for wildlife and can be more aesthetically pleasing than clearcuts. Historically, this system has been used extensively where natural regeneration is preferred or where artificial regeneration is difficult or costly. The technique supports a more gradual return to forest cover compared to other methods.
