The second bulletin in a series informing stakeholders of the progress of the MPI-led work programme addressing the inconsistent treatment of forestry activities under the Resource Management Act. This issue looks at the progress of the cost benefit analysis, forest planning rules that can be applied nationally and improving how the erosion susceptibility classification is applied. current 17 April 2014
The oreo fisheries chapter is the seventh chapter of Part 1B of the National Deepwater Plan. It highlights the two main oreo species, black and smooth, which are managed as a species complex. It covers all but one (OEO10) of the oreo stocks. It includes an overview of each fishery, details of non-target interactions including seabirds and marine mammals, fishery specific Operational Objectives, and how performance against these objectives will be measured. current 15 April 2014
The Ministry for Primary Industries (MPI) is seeking feedback and additional information from tangata whenua, the fishing industry, other stakeholders and interested parties on proposals to increase the in-season Total Allowable Catch (TAC) for the inshore fish stocks RCO 3. The proposal focuses on increasing the value fishers obtain from sustainable use of this well-managed inshore fishery by increasing the quantity of Annual Catch Entitlement (ACE) available to fishers. current 14 April 2014
Describes data for the 2013 stock assessment of CRA 2. Catch estimates for the commercial, recreational, customary and illegal fisheries were made by season and by size-limited and non-size-limited fisheries. CPUE was standardised by season using both estimated and landed catches. Length frequency data from observers and logbooks were collated by source and season. Analysis of logbooks showed no evidence of high-grading in CRA 2. Exploratory fits to tag-recapture data are described. current 14 April 2014
Describes management procedure development for CRA 9 using estimated catch and standardised CPUE data from 1963. Simple models were fit, stabilised by a prior on intrinsic rate of increase developed from tag-recapture data and assumed mortality, then used as operating models with stochastic variation in production and observation error. More than 1100 harvest control rules were tested with the base case and robustness trials; one has now been accepted by the Minister for 2014-15. current 14 April 2014
Describes stock assessment of lobsters in CRA 2 and management procedure evaluations, using the length-based multi-stock model MSLM fitted to CPUE, size and tagging data. The work used McMC simulations. Current biomass is below Bref but well above Bmsy and Bmin. Management procedures were “plateau step” rules tested with seven alternative operating models; final candidates were presented to the National Rock Lobster Management Group. A technical glossary is provided. current 14 April 2014
Briefing paper seeking approval of proposed changes to the Agricultural Inventory methodology following new science outcomes agreed by the Agriculture Inventory Advisory Panel. current 11 April 2014
This panel brief seeks approval from the Agricultural Inventory Advisory Panel, held on 12 November 2013, to apply an efficacy scalar value of 0.55 to the fraction of nitrogen in fertiliser that volatilises (Fracgasf) value where fertilisers containing urease inhibitors are applied. current 11 April 2014
This report to the Agricultural Inventory Advisory Panel Inventory panel, held on 12 November 2013, seeks approval to change the partitioning of nitrogen between dung and urine for cattle, sheep and deer. current 11 April 2014
The aim of the present report is to examine alternative methods of predicting the partitioning of N between urine and dung in farmed ruminants and to assess the impact on the national N2O inventory. current 11 April 2014
