Crosby et al. (1976) subdivided the New Zealand mainland (North, South, and Stewart Islands, plus nearby inshore islands) into 29 approximately equalsized areas, and defined two-letter codes for each. The codes and boundary definitions for these areas were provided on a separate, large map enclosed with the journal issue. These areas were modified from the areas used as weather forecast districts by the New Zealand Meteorological Service, and their main purpose was to facilitate the arrangement, retrieval, and documentation of specimens in the New Zealand Arthropod Collection (NZAC). The codes have subsequently been used in other collections, for computer databases, and in publications as a convenient way of categorising specimen data.

The New Zealand Journal of Zoology paper is provided here as an attachment to this record and is available for download.

LENZ - Mean annual temperature

Added
27 May 2010

This dataset was first added to LRIS Portal on 27 May 2010.

Mean annual temperature data layer used in the creation of Land Environments of New Zealand (LENZ) classification. The classification layers have been made publicly available by the Ministry for the Environment (see data.mfe.govt.nz/layers/?q=LENZ for to access these layers).

Mean annual temperature is recorded in °C. The climate station data used in the development of this climate surface were derived from summaries of climate observations published by the New Zealand Meteorological Service, using data collected over the period from 1950-1980. The resulting data layer was created by coupling a 100 m DEM with a thin-plate spline surface fitted to an irregular network of 300 meteorological stations. The resulting 100 metre layer was then interpolated to 25 metres using bilinear interpolation. Following conventions used in the calculation of climate summary statistics, the values used to fit the surface consisted of the mean of the 12 monthly averages for daily average temperature.

This layer has been multiplied by a factor of 10 (i.e. converted into an integer grid) to save space and make the grids more responsive. A value of 136 is actually 13.6 °C.

Additional details such as the climate station locations used in the creation of the layer and error maps are defined in the attached LENZ Technical Guide.

Vegetative Cover Map of New Zealand

21 May 2015

This dataset was first added to LRIS Portal on 21 May 2015.

The 1:1,000,000 scale Vegetative Cover Map of New Zealand is the first vegetation survey which can be applied nationally for planning, research, and education. It optimises the cartographic potential of the vegetation information available in the early 1980s and provides a historical record which will aid in future analyses of vegetative cover and land utilisation. The map classification recognises 47 Vegetative Cover Classes identified by alphanumeric code and 17 Vegetative Cover Elements identified (only on the printed map) by symbols and patterns. The map is published as two sheets 730mm x 880mm covering the three principal islands of New Zealand and all offshore islands within 100km of the coast. The map was accompanied by a 153 page, illustrated, book which discusses New Zealand's vegetation and describes the 47 classes.

FSL Soil Drainage Class

Added
04 Jun 2010

This dataset was first added to LRIS Portal on 04 Jun 2010.

The New Zealand Fundamental Soil Layer originates from a relational join of features from two databases: the New Zealand Land Resource Inventory (NZLRI), and the National Soils Database (NSD). The NZLRI is a national polygon database of physical land resource information, including a soil unit. Soil is one in an inventory of five physical factors (including rock, slope, erosion, and vegetation) delineated by physiographic polygons at approximately 1:50,000 scale. The NSD is a point database of soil physical, chemical, and mineralogical characteristics for over 1500 soil profiles nationally. A relational join between the NZLRI dominant soil and derivative tables from the NSD was the means by which 14 important soil attributes were attached to the NZLRI polygons. Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layer contains attributes relating to soil drainage. Soil drainage is described as a class. Drainage classes are assessed using criteria of soil depth and duration of water tables inferred from soil colours and mottles. Drainage classes used here are the same as those used in the NZ Soil Classification (Hewitt 1993), and outlined by Milne et al. (1995).

LENZ - Annual water deficit

Added
30 May 2010

This dataset was first added to LRIS Portal on 30 May 2010.

Annual water deficit data layer used in the creation of Land Environments of New Zealand (LENZ) classification. The classification layers have been made publicly available by the Ministry for the Environment (see data.mfe.govt.nz/layers/?q=LENZ for to access these layers).

Based on a water balance model using monthly estimates of mean daily temperature, mean daily solar radiation, and mean rainfall, this layer is used as an indicator of soil dryness. The layer calculated as the sum of any deficits between rainfall and potential evaporation calculated using the method of Priestley and Taylor (1972). The resulting 100 metre layer (The temperature, solar radiation and rainfall layers were all 100m) was then interpolated to 25 metres using bilinear interpolation.

The climate station data used in the development of this climate surface were derived from summaries of climate observations published by the New Zealand Meteorological Service, using data collected over the period from 1950-1980 The data layer was derived from surfaces fitted to monthly data describing daily average temperature, daily solar radiation and monthly rainfall. The rainfall surface was fitted using NZMG coordinates, elevation, and a model describing relationships between topography and westerly winds.

Having derived the 36 input climate layers, an empirical model was first used to calculate the monthly potential evaporation from the monthly estimates of solar radiation and temperature. These estimates of evaporation were then compared with the monthly rainfall estimates. Where the rainfall exceeded evaporation, the monthly deficit was assumed to be zero, but where monthly evaporation exceeded monthly rainfall, the shortfall was accumulated through the year to derive an estimate of the annual water deficit.

The units for this layer are in mm, higher values are areas that have a larger deficit.

Additional details such as the climate station locations used in the creation of the layer are defined in the attached LENZ Technical Guide.

This layer comes from the Threatened Environment Classification (TEC) version 2012, which is a source of national scale background information on New Zealand's land environments. Specifically, it shows how much native (indigenous) vegetation remains within land environments, and how past vegetation loss and legal protection are distributed across New Zealand's landscape. The TEC uses indigenous vegetation as a surrogate for indigenous biodiversity. This includes indigenous ecosystems, habitats and communities: the indigenous species, subspecies and varieties that are supported by indigenous vegetation, and their genetic diversity. The TEC is most appropriately applied to help identify places that are priorities for formal protection against clearance and/or incompatible land-uses, and for ecological restoration to restore lost species, linkages and buffers. The TEC is a combination of three national databases: Land Environments New Zealand (LENZ), classes of the 4th Land Cover Database (LCDB4, based on 2012 satellite imagery) and the protected areas network (version 2012, reflecting areas legally protected for the purpose of natural heritage protection).
