Developmental Stages

Seedling 0 days – 10 years

Human equivalent: 0-1 year

Tiny, slow-growing. Harsh alpine conditions. Most don't survive.

Sapling 10 years – 50 years

Human equivalent: 1-5 years

Still small. Dense wood forming. Adapting to wind and cold.

Young Tree 50 years – 500 years

Human equivalent: 5-15 years

First cones produced. Growing maybe 1 inch diameter per century.

Mature 500 years – 2k years

Human equivalent: 15-40 years

Twisted, gnarled form. Much of the tree is dead wood — only a strip of bark lives.

Ancient 2k years – 5k years

Human equivalent: 40-80 years

Mostly dead wood. A thin ribbon of living tissue. Grows so slowly that decay can't keep up.

Fun Fact

Methuselah was already 1,000 years old when the last mammoth died on Wrangel Island. It was 3,000 years old when Rome was founded. Its location is kept secret to prevent vandalism.
