| The Technology |
| A Tag (chip) is placed inside a tree at an early age. |
| Forest managers take portable readers to the field. |
| The reader emits a magnetic field which the tag uses to power up and transmit its ID back to the reader. |
| A database of tree information can be created. |
| The tree grows up from the top and around the tag, assuring a predictable reading height. |

| Tags Provide Serial Numbers for Trees |
| Keep track of forest information at the scale of individual trees. |
| Know exactly which trees are in a unit or conservation easement. |
| Keep track of trees from planting to maturity. There are over 1 billion seedlings planted per year in the U.S. |

The reader sends out a signal. The tag is passive and transmits its ID using the power from the reader's signal.

Database Possibilities
Each RFID tag has a unique number. This number is used as a database key to keep track of individual tree information such as: originating nursery, type of tree, planter, date planted, GPS location, important genetic information, etc. |
