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 It comprises two sets of data compiled using stereo aerial photography, published and unpublished reference material, and extensive field work: 1. 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. 2. A Land Use Capability (LandUseCapability) 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 LandUseCapability classification. Provided the LUC and Land Resource Inventory (LRI) is used properly it could be possible to predict some of the potential effects of land use change on erosion.The Land Resource Inventory comprises serveral physical resource themes: Land Use capability, Lithology, Soil etc.This dataset is a polygon layer delineating land areas classified according to their capability to sustain continous production. Land Use Capability (LUC) is a hierarchical classification identifying: the land's general versatility for productive use; the factor most limiting to production; and a general association of characteristics relevant to productive use (e.g, landform, soil, erosion potential, etc.). LUC classifications have been constructed for each NZLRI survey region. These individual classifications have been correlated to North and South island classifications to permit wide-area analyses.The NZLRI is a spatial dataset contaning similar information to that in the NZLRI worksheets. Each polygon describes a parcel of land in terms of five characteristics (rock, soil, slope, erosion, vegetation). The LUC rating of each unit is based on an assessment of the ability of these five factors to provide sustained agricultural production, This also considers climate, effects of past land use and potential for erosion.As there are separate LUC classifications for each NZLRI survey region, a Land Use Capability expression must be interpreted in the contect of it's LEGEND. The Bay of Plenty region is made up of parts of 6 NZLRI survey regions however a standardised LUC for the whole North Island has been included and should be used for the Bay of Plenty.Dataset was published in 1979 but work was started in 1973. It is still being maintained as new data and funding becomes available. Was originally created by the Ministry of Works and Development to assist the National Water and Soil Conservation Organisation in fulfilling its responsibilities for soil conservation and erosion control. This required land resource information of a uniform standard and quality at the local, regional and national levels. Please read Land Resource Inventory version 2 Documentation.pdf (Objective ID A478753) for more information.
