New Zealand Seaweeds is the first photographic identification guide to New Zealand’s unique marine algae, by the country’s pre-eminent seaweed expert Wendy Nelson. Across three main sections covering green, brown and red algae, over 150 genera and 250 key species are described. Each species entry includes up-to-date information on nomenclature, type locality, morphology, habitat, distribution and notes on identification and key characteristics. The guide contains over 500 illustrations, with each entry illustrated by either underwater or coastal photographs and supplemented by herbarium scans, microscopic photographs or reproductions of celebrated botanical artist Nancy Adams’ paintings from the original Seaweeds of New Zealand: An illustrated guide. Informative introductory chapters and breakout boxes introduce New Zealand’s seaweeds, giving an overview of the country’s aquatic flora and its unique features, information about the coastal environment, macroalgal ecology, distribution and introduced/invasive species, plus material on the uses of macroalgae (particularly in New Zealand by Māori) and the widespread commercial applications of these diverse plants. An essential, all-new reference for professional and recreational users.
