Indicator Plant
Definition
A pollen type whose presence in a honey assemblage is highly diagnostic of a geographic origin because the plant only grows or is commercially cultivated in a specific region.
- Field
- Melissopalynology
- Function
- Diagnostic of geographic honey origin
- Basis
- Restricted natural range or localised cultivation
Common questions
How does an indicator plant's pollen differ in evidentiary value from a common background pollen in honey?+
A background species like clover or dandelion grows almost everywhere bees forage, so its presence says little about origin, whereas an indicator plant restricted to one region narrows a honey sample's likely source area substantially.
Can a single indicator plant pollen grain be enough to establish honey origin?+
Analysts look at the overall pollen assemblage and relative abundance rather than a single grain, since trace contamination or wind-blown pollen can appear at low levels, so an indicator taxon carries most weight when present at meaningful frequency.
