Macrobotanical Evidence
Definition
Plant material visible to the naked eye or under low magnification: leaves, seeds, fruits, stem fragments, bark. Complements microbotanical (pollen, diatom) evidence by providing coarser but directly identifiable material.
- Visibility
- Naked eye or low magnification
- Examples
- Leaves, seeds, fruits, stem fragments, bark
- Complements
- Microbotanical evidence (pollen, diatoms)
- Identification level
- Often achievable to species level
Common questions
How does macrobotanical evidence complement microbotanical findings in a case?+
Macrobotanical fragments can usually be identified to a specific plant species by visual and structural features, providing a stronger anchor than the broader, more statistical habitat picture pollen or diatom analysis alone can suggest.
What can macrobotanical fragments recovered from a vehicle or clothing establish?+
Because many plants have restricted ranges or seasonal fruiting and flowering periods, a recovered fragment can place a person or object at a location and time window, supporting or contradicting an account of events.
