LUCAS New Zealand Land Use Map 1990 2008 2012 (v016)

The Ministry for the Environment, LUCAS Land Use Map is composed of New Zealand-wide land use classifications (12) nominally at 1 January 1990, 1 January 2008 and 31 December 2012 (known as "1990", "2008" and "2012"). These date boundaries were dictated by the First Commitment Period of the Kyoto Protocol. The layer can therefore be used to create either a 1990, 2008 or 2012 land use map depending on what field is symbolised.

LUM tracks and quantifies changes in New Zealand land use so that Land Use, Land Use Change and Forestry (LULUCF) sector carbon accounting can be calculated for national Net Position, Kyoto Protocol and United Nations Framework Convention on Climate Change (UNFCCC) reporting.

The Government has committed $100 million over 10 years through the Freshwater Improvement Fund to support initiatives which improve the management of fresh water within quality and quantity limits.

The fund focuses on projects that will make a significant and measurable improvement to rivers, lakes, streams, groundwater and wetlands, with priority on the most vulnerable catchments.

This dataset shows catchments that have been classified as vulnerable (as defined by the criteria for the Freshwater Improvement Fund).

The REC groups rivers and parts of river networks that share similar ecological characteristics, including physical and biological. Rivers that share the same class can be treated as similar to one another and different to rivers in other classes. The REC classification system groups rivers according to several environmental factors that strongly influence or cause the rivers’ physical and ecological characteristics (climate, topography, geology and land cover). A catchment is a polygon that defines the upstream watershed of a river system or sub-system. Land cover within the catchment was used to populate the river classification factors (see table 1.1 of the User Guide www.mfe.govt.nz/environmental-reporting/about/tool...).

Land Environments of New Zealand (LENZ) is a classification of fifteen climate, landform, and soil variables chosen for their relevance to biological distributions. Classification groups were derived by automatic classification using a multivariate procedure. Four levels of classification detail have been produced from this analysis, containing 20, 100, 200, and 500 groups respectively.

The New Zealand River Environment Classification (REC) organises information about the physical characteristics of New Zealand's rivers. Individual river sections are mapped according to physical factors such as climate, source of flow for the river water, topography, and geology, and catchment land cover eg, forest, pasture or urban. Sections of river that have similar ecological characteristics can then be grouped together, no matter where they are.

This information is mapped for New Zealand's entire river network - over 425,000 kilometres of river. Different types of rivers respond differently to the pressures placed on them - the REC can be used to highlight the most appropriate management tools and approaches to reduce these pressures for each river type. Information from the classification is used to develop policy, assess the environment, and report on the quality of river water.

Stream order is the numerical position of a tributary or section of a river within the entire network. Headwater streams are assigned a stream order of 1. When two tributaries of the same stream order meet, the order increments by one for the next section downstream. However, if two sections meet where one section has higher order than the other, the next section downstream has the same order as the highest upstream section.

Erosion susceptibility is defined by the predisposition (of a land unit) to erode, preparatory factors (such as the are removal of forest), the Likelihood and severity of an erosion event, and the consequences of an erosion event.

The Erosion Susceptibility Classification uses 4 fields: Legend (NZLRI Region); LUC (LUC unit code); PolyMaxSev (maximum erosion severity for each polygon unit); ESC (erosion susceptibility class for each polygon).

This version has removed the LUC from the attribute table and dissolved the geometry to the erosion susceptibility class.

River water quality water is valued for many reasons including ecological function and habitat, recreational value, its role in supporting people and industry, and its cultural significance. Nutrients such as nitrogen and phosphorus are essential for plant growth, however too much in rivers can lead to ‘nuisance’ growths of river algae and aquatic plants, degrading habitat. High concentrations in the form of ammoniacal nitrogen and nitrate-nitrogen can be toxic to fish and other aquatic animals. Water clarity is a measure of underwater visibility, and affects habitat of aquatic life such as fish and birds, and can also impact on aesthetic values and recreational use of rivers and streams. Escherichia coli bacteria can indicate the presence of pathogens (disease-causing organisms) from animal or human faeces, which can cause illness.
State (percentile) results for the following parameters, by monitored site for the period 2009–2013, are provided. Refer to Larned at al (2015) for further details.

 Clarity (CLAR), m
 Ammoniacal nitrogen (NH4N), mg/m3
 Nitrate nitrogen (NO3N), mg/m3
 Total nitrogen (unfiltered) (TN), mg/m3
 Dissolved reactive phosphorus (DRP), mg/m3
 Total phosphorus (unfiltered) (TP), mg/m3
 Escherichia coli (ECOLI), n/100 mL
