Life cycle

The life cycles of trees, especially conifers, are divided into the following stages in forestry for survey and documentation purposes, though the boundaries between stages vary among foresters:

  1. Seed
  2. Seedling: the above-ground part of the embryo that sprouts from the seed
  3. Sapling: After the seedling reaches 1 m tall, and until it reaches 7 cm in stem diameter
  4. Pole: Trees from 7–30 cm diameter
  5. Mature tree: over 30 cm diameter, reproductive years begin
  6. Old tree: dominate old growth forest; height growth slows greatly, with majority of productivity in seed production
  7. Overmature: dieback and decay become common
  8. Snag: standing dead wood
  9. Log/debris: fallen dead wood
