Objective
Assess the prevalence of herbivory and powdery mildew on oak leaves, identifying specific gall and miner species present.
- Collection
- Utilize an arborist throw-line launcher to collect 30 sun-exposed leaves from the crowns of each oak tree at 31 different sites.
- Storage
- Store leaves dry in envelopes to preserve their physical state until analysis.
- Examination
- Examine each leaf under a microscope to identify and record instances of herbivory damage and powdery mildew presence. Galls and miners should be identified at the species level where possible.
