- Summary
- The consent is subject to several monitoring conditions including: i) to assess the sub-lethal effects of Gallant, including its bioaccumulation in invertebrates; ii) iii) iv) to assess the acute effects of Gallant on non-target species and macroinvertebrates; to assess the effects of decaying and/or dead plant material on the environment; to assess the effects of sediment release on the immediate environment and the potential effects on the wider environment. NIWA was commissioned to design a monitoring programme to comply with conditions (iii) and (iv) above. Our brief was as follows: a) the monitoring programme should be applicable in other estuaries around the country; b) on the basis of the data contained in the BoP (1994) report, the sampling intensity was to be designed to detect a 50 % change in the three most abundant taxa; c) enough detail regarding the statistical testing procedures was to be included for field staff to do the necessary statistics using Excel functions or an ordinary calculator.
