1) The Two-Signal Rule: leaf + bark
Most mix-ups happen when you rely on one clue. In the field, take two photos:
- Leaf (or needles): full outline + edge detail. If compound, include the whole structure.
- Bark: straight-on trunk texture photo—often more unique than leaves.
- Bonus: a wide “context” shot showing branching style and silhouette.
2) Seasonal shortcuts: buds, needles, cones
- Buds: size and arrangement can narrow families quickly.
- Needles: count per bundle and length are strong signals for conifers.
- Cones/seed pods: photograph in-hand for scale.
3) Photography upgrades (instant accuracy boost)
- Light: open shade is great for bark texture.
- Focus: tap-to-focus on leaf edges or bark ridges.
- Scale: include a coin/key/fingertip next to the leaf.
- Background: hold the leaf against a plain surface (sky, jacket, notebook).
4) Responsibility
- Don’t ingest plants based on an app result alone.
- Sensitive skin: if unknown and you’re rash-prone, avoid bare-hand handling.
- Leave No Trace: take photos—don’t damage living plants for “better shots.”
