| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Fire Control (fire_control) | required | 93% | primary_source | Birch bark tar must be intentionally manufactured by heating bark; the cited paper states that all production methods require knowledge of fire to transform bark into tar. |
|
| Foraging & Botany (foraging_and_botany) | enabling | 74% | primary_source | The scoped adhesive depends on selecting birch bark as the raw plant material; this is a material-selection enabler rather than a hard botanical-science prerequisite. |
