This collection contains aquatic plant, bryophyte, and macroalgae specimens collected as vouchers during point counts (NEON sample class: apc_perTaxon_in.sampleIDplant). Aquatic plant, bryophyte, and lichen point count data are collected three times per year at wadeable streams, during aquatic biology bout windows, roughly in spring, summer, and fall. Data are collected at ten permanent transect locations that are revisited during each sampling bout. See related links below for protocols and NEON related data products.
