Habitat characteristics of geothermally influenced waters in the Waikato
Abstract
The Waikato province contains almost 80% of New Zealand's geothermal systems (Environment Waikato 1998). Thus, this region represents an important resource in terms of the habitat associated with increased soil and water temperatures for both geothermal vegetation (Beadel & Bill 2000) and aquatic organisms (Parkyn & Boothroyd 200; Duggan & Boothroyd 2001). Associated issues and values range from exploitative resource use, such as thermal energy extraction and the utilisation of mineralised fluids, to historical, amenity, cultural, spiritual, conservation and scientific values (Environment Waikato 1998; Merrett & Clarkson 1999). The environmental management objectives of Environment Eaikato are derived from these. The objectives are to maintain the variety of characteristics and to achieve protection and efficient of the regional geothermal resource (Environment Waikato 1998).
The present report provides an inventory of the ecological and physical/chemical characteristics of geothermally influenced water in the Waikato province. The area was surveyed between April 10th and May 9th and assessments of habitat and in situ measurement of environmental parameters (eg DO, pH, conductivity, temperature) were used to determine habitat characteristics.
