This data set is a mask of the temporal and non temporal changes made between land cover database v3.0 and the previous version (land cover database-2). The non-temporal changes include errors in the earlier mappings, step artefact removal, and coastline adjustments. Note: the non-temporal attribute is named "NoTemporal" due to a character length limitation.

An “authority” attribute is also available in this layer indicating the source of the change for both non-temporal and temporal changes mapped. The Authority attribute indicates who identified the change, where;

1 = Landcare Research.
2 = Regional Council or Territorial Authority.
3 = Department of Conservation.

This layer was produced with a map tolerance of 10cm.

Funding is from the Ministry for Science and Innovation under contract CO9X1101, which was contributed to by the Ministry for the Environment. The Department of Conservation and individual regional councils and territorial authorities have made significant in kind contributions by checking the draft mapping for their areas of interest.

This dataset was first added to LRIS Portal on 28 May 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 mineralological 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 the best available data (as at 2000) of Profile Readily Available Water (PRAW) which estimates water readily available to plants for the soil profile to a depth of 0.9 m, or to the potential rooting depth (whichever is the lesser). Values are weighted averages over the specified profile section (0-0.9 m) and are expressed in units of mm of water.

This layers contains the permeability profile attribute. Permeability is the rate that water moves through saturated soil. The permeability of a soil profile is related to potential rooting depth, depth to a slowly permeable horizon and internal soil drainage. Permeablity classes are from Clayden and Webb (1994).

Updated
04 Aug 2017

This dataset was last updated on LRIS Portal on 04 Aug 2017.

A 25m resolution grid of aspect in degrees north of south, for use as a regression variable for calculating BASE carrying capacity using Model 1 where:

if aspect <= 180 then aspect180 = aspect

else if aspect > 180 then aspect180 = 360 - aspect

This aspect data is symmetrical around north-south, meaning east and west are considered equivalent (90 degrees) to avoid problems in regression where normal aspect values of 0 and 360 degrees both equal the same north.

New Zealand's potential forest composition was predicted from regressions relating the distributions of major canopy tree species to environment. Environmental variables, chosen for their correspondence to major tree physiological processes, included annual and seasonal temperature and solar radiation, soil and atmospheric water deficit, soil leaching, slope, and soil parent material and drainage. Environmental values were estimaged both for a large set of irregularly distributed plots describing forest composition, and points on a 1-km grid across New Zealand. Regressions were fitted to the ploy data species by species, with those for the four Nothofagus species also including terms to correct for the effects of their geographic disjunctions. Predictions of species abundance were then made for the grid data set, and the resulting matrix was classified to derive groups of similar composition. This data is expected to provide a context for both the assessment of the biodiversity value of surviving forest remnants and for the subsequent management and/or restoration of these sites.

A 25m grid of BASE carrying capacity for ALL leases (original model for all lease properties). This layer is buffered around the lease boundaries supplied by LINZ by roughly 5km to ensure that it can be reused for analysis where property boundaries are found to be incorrectly mapped or out-of-date.

This layer provides a classification of New Zealand ecosystems according to plant composition. Generalized Dissimilarity Modelling was used to produce a model of biotic composition in relation ship to environment and biogeography. This model was used to transform and scale environmental layers to predict community composition. The transformed environmental layers were then used to classify New Zealand into areas of similar biotic composition. The biotic data used for this model include all vascular plant taxa from NVS recce data and estimated community compositions from pollen data.

Chemical limitations to plant growth 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).

This data layer defines three classes of soil based on factors that lead to the accumulation of chemicals that limit plant growth. Classes were differentiated either by their parent material or by their position in the New Zealand Soil Classification. Three classes of chemical limitations, Low (1), Moderate (2) and High (3). The class defined as "0" signifies areas where there are no soil attributes recorded (i.e. high peaks of the Southern Alps).

Additional details such as discussion about the accuracy and reliability of the LENZ soil layers and the technical definitions of the categories in this layer are defined in the attached LENZ Technical Guide.
