Taranaki Irrigation Study 2012
Transforming Taranaki, a booklet published in November 2011, tells how farmers, with the encouragement of the Council and the dairy industry itself, are becoming better guardians of the environment by working to reduce the amount of diffuse-source pollution going into the region’s rivers and streams – the material that is washing off pastures and into waterways. The publication describes the Riparian Management Programme and its successes so far.

A photographic guide to freshwater invertebrates of Taranaki rivers & streams
Invertebrates are a vital part of the freshwater ecosystem and can tell us a great deal about the state of a waterway's health. This Guide introduces all of the major invertebrate groups using microscope images, with a brief description of the habitat preferences of each group.
