Project and client

A multi-factor land resource survey was carried out in part Tairua catchment, Coromandel, by Landcare Research New Zealand Ltd, Aokautere, for Environment Waikato, Hamilton, in May 1993.

Objectives

• To map the land resources of part Tairua catchment at a scale of 1:50 000 .
• To assemble map units into Land Use Capability (LUC) units that together provide a basis for land management decisions, natural resource research and environmental monitoring.

Methods

• Primary inventory map units were delineated on stereo-photograph pairs with regard to the landform, slope angle, soil unit, and rock type. One week was spent in the field verifying the defined units. Secondary, or final inventory map units were then defined on the basis of differences in land cover /use, erosion attributes and rock-related factors such as % bare rock and regolith depth. Units were delineated at a scale of 1:50 000.
• The inventory map units were grouped into LUC units on the basis of their unique assemblage of physical characteristics.
• The land resources, inventory map units and LUC units are described in this report.
