Plate showing sampling methods across all forest types. Examples of what leaves look like coming out of the sediment, trowel for scale (A), and sampling within the dynamic river (B) and tributary (E) at the La Selva Biological Research Station. Dense leaf packs (C,F) and overbank sampling (D) at the Smithsonian Environmental Research Center (SERC). Sampling from within fine sediment at Harvard Forest (G). Leaves were carefully rinsed of sediment prior to drying and pressing (H).
