Mangaoraka Stream at
Corbett Road and Punehu Stream at SH45). Significant deteriorations in black disc clarity
were recorded at three sites, two of which reflected historical erosion events in the
headwaters.
The most improvement in long term water quality has been illustrated in the Waingongoro
River at SH 45, with significantly improving trends in DRP and total phosphorus, and with
reduction in nitrate and total nitrogen by slightly less than the rate defined as significant.
This improvement
following
the same procedure as short vegetation, as fencing has been shown to result in rapid reductions in
sediment exports (McKergow, Weaver et al. 2003), although little is currently known about fencing
impacts on bank erosion rates (Hughes 2016), which will depend on stream size, bank height, and
bank material.
Index 3 was designed to more accurately quantify the effects of stream shading by riparian
vegetation by comparing shading to the relative width of the stream.

1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by
NPDC, this report also assigns them a rating for their environmental and
administrative performance during the period under review.
Environmental performance is concerned with actual or

the vast majority of the ring plain now encompassed by the self help programme. However it is unlikely to be cost effective to apply the
programme to properties in the eastern hill country.
The Council proposes to maintain low possum numbers through a sustained control Programme, by continuing to maintain landholders
capacity to carry out control, but at a less intensive rate than properties in the self help programme. This will

1.1.4 Evaluation of environmental and consent performance
Besides discussing the various details of the performance and extent of compliance by
the consent holder/s during the period under review, this report also assigns a rating
as to each Company’s environmental and administrative performance.
Environmental
grating system on the original outlet from the second pond was
undertaken in late 1999. This outlet was then sealed but was raised and re-opened in
2004 and was utilised whenever stormwater infiltration volumes increase effluent rates
beyond the capacity of the re-positioned outlet.

- The farm is managed to minimise nutrient losses overall (for example cut and carry of pasture
to remove nitrogen);

- Riparian planting and fencing (stock exclusion) will improve the water quality of the stream

3.8.8 Acoustic source tests
Seismic source tests will be subject to the relevant soft start procedures for each survey
level, though the 20-minute minimum duration does not apply. Where possible, power
should be built up gradually to the required test level at a rate not exceeding that of a
normal soft start. Level 1 and 2 seismic source tests with a maximum
