The beach database contains data from surveys of beaches which are used to monitor the population size and length structure of selected shellfish species at various beaches within the inter-tidal zone. Traditionally, these surveys have been done for toheroa (Paphies ventricosa), but have also included cockles (Austrovenus stutchburyi), large wedge shells (Macomona liliana), pipi (Paphies australis), tuatua (Paphies subtriangulata) and sea lettuce (Ulva). Sampling protocol. Predominately, beaches are sampled with transect lines, with samples dug from quadrats along the transect line, and the beach material sieved for shellfish. Sampled data are from 1969. Data collection is ongoing. Sampling frequency: variable. Lat/Long provided for some data. Sampling sites range from Ninety Mile Beach in the north to Te Waewae Bay in the south, including the Bay of Plenty. Sampling methods: core, quadrat, transect
