devices and planting of riparian
vegetation are carried out, in line with consent conditions.
Monitoring programmes for surface water abstraction include checking compliance with the residual flow
conditions of the consent. Residual flow conditions set minimum environmental flows to be maintained
during pumping in the waterways downstream from the abstraction point. Compliance with the residual
flow conditions is assessed through hydrological flow gaugings which are carried out during low flow
deforestation and hydro-electric development in stretches of river
that support blue duck.
Set traps on your property to control predators where blue duck are
present.
Retire and plant river and streamside riparian vegetation to enhance and
maintain water quality.

CONSERVATION
The blue duck is an endemic New
land management in the region is important.
Sustainable land use means using the land according to its capacity for sustained production. That is,
matching the appropriate land use with land type. In addition to the riparian planting programme focused
on Taranaki’s ring plain (detailed in Chapter 3—Fresh water), the Council’s sustainable land management
programme focuses largely on the region’s eastern hill country and coastal sand areas, where soil is most
vulnerable to erosion.
impacts of minor freshes have
been reported from time-to-time (TRC 1992; TRC 1993; TRC 1995).
The Patea Catchment above the dam (including the Mangaehu sub catchment) covers an area of 86,944.3
ha, with an urban area of 840.9 ha (1%). Riparian plans have been prepared for an area of 22,048.4 ha (25%
of catchment). As at June 2018, some 231 riparian plans have been prepared by the Council in relation to
properties within the Patea River sub-catchment. An additional three plans have been

3.1 Mr G K Bedford, Director-Environment Quality, spoke to the memorandum
presenting the background and findings of a report the Council commissioned the
National Institute of Water and Atmosphere (NIWA) to undertake, ‘Analysis of stream
which were not transported as bedload but were deposited as a part of
the formation and play an important control effect within the channel.
All ring plain watercourses transport gravel and sand as bedload. Within the last
two decades a series of heavy rainfall events has caused increased erosion in the
upper catchments. This has led to an increase in bedload within watercourses which
has induced instability within channels resulting in damage to riparian lands and
assets within or

Activity that damages these wetlands would be a non-
complying activity and resource consents would be
unlikely to be granted. However, grants can be provided to

Sustainability - Positive The wetland is in good vegetative condition, fully fenced, with
margins being planted through the riparian scheme. New fencing is
underway around one section of forest, with temporary fencing
being erected around the other sections as and when required.
Ecological processes will remain resilient to existing threats under
appropriate management.
