How Tree Numbers Work

Old Growth Mill assigns a unique tree number to every documented tree. This number is the identifier that connects the documentation system: YouTube videos, the tree map, blog posts, and inquiries. When you reference a tree number, everyone is talking about the same tree.

The format is intentionally simple: YYYYMM## (Year, Month, Sequential Number). For example, 20250101 means the first documented tree in January of 2025.

This system locks a tree to a unique identifier that is easy to write down and easy to search. It also creates a time-based index that stays consistent year after year.

Tree numbers are assigned after documentation begins. A tree number is not an inventory label and does not imply availability. A tree can be documented and discussed while still being in an early evaluation stage.

When contacting Old Growth Mill about a tree, the tree number is the most useful information you can provide. It keeps the conversation specific and grounded in recorded documentation.

Practical takeaway: the tree number is the key that links location, video documentation, and discussion. Use it whenever you reference a specific tree.
