Description: The New Zealand Land Resource Inventory (NZLRI) is a national database of physical land resource information. It comprises two sets of data compiled using stereo aerial photography, published and unpublished reference material, and extensive field work:An inventory of five physical factors (rock type, soil, slope, present type and severity of erosion, and vegetation). A 'homogeneous unit area' approach is used to record the five physical factors simultaneously to a level of detail appropriate for presentation at a scale of 1:50,000.A Land Use Capability (LUC) rating of the ability of each polygon to sustain agricultural production, based on an assessment of the inventory factors above, climate, the effects of past land use, and the potential for erosion. The NZLRI covers the country in 11 regions, each with a separate LUC classification.The first edition NZLRI provides national coverage from mapping between 1973 and 1979 at a scale of 1:63,360. A limited revision regional upgrade of the north Waikato area was completed at a scale of 1:63,360 in 1983. Second edition NZLRI regional upgrades at a scale of 1:50,000 have been completed for Northland, Wellington, Marlborough and Gisborne-East Cape. Third edition NZLRI layers contained a restructured polygon attribute table to allow the core NZLRI to complement the newly created fundamental soil layers with minimal duplication.Update of Edition 3 NZLRI. This update involves ++no new mapping++, but does include a ++new National Land Use Capability legend++ correlated for all regions across New Zealand. Attributes include original LUC units codes and unit descriptions so that users more familiar with original regional codes and North Island correlations can track the pedigree of units from old to new codes and descriptions.For more information please visit: https://lris.scinfo.org.nz/layer/48076-nzlri-land-use-capability-2021/Updated August 2023. Clipped to Otago Region 2023.Note: Field LUCSimple added, simplifying LUC for analysis.

Description: Rabbit numbers counted by pest destruction boards to measure the affect of control operations are used to assess the relationship between recorded elements of land resources (parent material, soils, vegetation, slope, erosion) and rabbit populations. The results of the study clearly confirm the often observed concentration of high rabbit populations on the brown-grey earth soils and a corresponding reduction in rabbit numbers with increased rainfall and pasture improvement.This analysis uses the NZLRI/FSL soils data to assign rabbit proneness. This analysis precedes the illegal release of rabbit haemorragic disease (RHD) in 1997 and does not factor in any interactions between environment and RHD in terms of assigning rabbit proneness.The symbology of the additional field 'Status' was created by assigning RCODE2 values to different proneness levels as follows;X: ExtremeH: HighM: ModerateL: LowO: Negligiblee: Not Classifiedi: Not Classifiedr: Not Classifiedt: Not ClassifiedMore Information: https://lris.scinfo.org.nz/layer/105591-new-zealand-rabbit-proneness/attachments/22995/Updated August 2023.

Description: LCDB is suitable for use in national and regional environment monitoring, forest and shrubland inventory, biodiversity assessment, trend analysis and infrastructure planning. The classification used in LCDBv5.0 is presented in the document 'LCDBClassesAtVersion5.pdf' and a table correlating LCDB classes over all versions is presented in the document 'LCDBClassCorrelations.pdf'. Both of these are among the accessory documents to this dataset in the LRIS portal (lris.scinfo.org.nz/). LCDB version 5.0 was released in January 2020 and includes corrections to all time steps1997/97, 2001/02, 2008/09, 2012/13 and 2018/19 for both the New Zealand mainland and Chatham Islands. A description of work undertaken for this release (including that of all earlier releases) is presented in the Lineage section. Of particular note at version 5.0 is the addition to LCDB, of attributes designed to readily identify and monitor wetlands over time and a similar capability to manage significant coastal changes. “EditAuthority” and "EditDate" are attributes, maintained since version 3.0 to indicate authorship and nominal date of polygon mapping, edit or change. Errors in the data due to misclassification (rather than land cover change) or poor delineation can be reported to Landcare Research for inclusion in the next release using the online feedback facility in lris.scinfo.org.nz/.For more information please visit: https://lris.scinfo.org.nz/layer/104400-lcdb-v50-land-cover-database-version-50-mainland-new-zealand/Updated August 2023.

Description: 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 best available, as at 2000, profile available water (PAW) data which estimates total available water 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.For more information please refer to https://lris.scinfo.org.nz/layer/48100-fsl-profile-available-water/Updated August 2023.
