S-map Soil Depth Aug 2024
Manaaki Whenua – Landcare ResearchSoil depth is defined according to a traditional agronomic concept of soil depth (Webb & Lilburne 2011). Note that while the layer defining soil depth may cause some restriction in root penetration, it does not necessarily define the base of the potential rooting depth. This layer is a "dissolved" representation of the soil depth attribute for S-map...Created 3 September 2024 • Updated 3 March 2025 -
NZLRI Erosion Type and Severity
Manaaki Whenua – Landcare ResearchThe NZLRI is a spatial database containing about 100,000 polygons (map units), each of which describes a parcel of land in terms of five characteristics or attributes (rock, soil, slope, erosion, vegetation). This layer represents a GIS dissolve on the erosion attribute of the NZLRI.Created 3 May 2018 • Updated 3 March 2025 -
LENZ - Slope
Manaaki Whenua – Landcare ResearchSlope 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 https://data.mfe.govt.nz/layers/?q=LENZ for to access these layers). This slope data layer is measured in degrees and was created from a 25-metre digital...Created 3 May 2018 • Updated 3 March 2025 -
PBC - Predicted Background Soil Concentrations, New Zealand (Deprecated)
Manaaki Whenua – Landcare ResearchDEPRECATED New layer can be found: https://lris.scinfo.org.nz/layer/114281-pbc-predicted-background-soil-concentrations-new-zealand-h3-resolution-9/ The Predicted Background Concentration (PBC) shapefile contains spatial information on the effective median, and 95th quantile estimates of the background concentration (mg/kg) of arsenic, cadmium,...Created 10 September 2023 • Updated 3 March 2025 -
S-map Relative Bypass Flow Susceptibility Aug 2024
Manaaki Whenua – Landcare ResearchRelative bypass flow is the potential susceptibility of water infiltrating at the soil surface to bypass the soil matrix as it drains through the soil. This is where the infiltrating water rapidly ‘short circuits’ the soil by percolating along preferential pathways (i.e., macropores, cracks, fissures, decayed-root channels). The vulnerability of land to...Created 3 September 2024 • Updated 3 March 2025 -
Basic Ecosystems
Manaaki Whenua – Landcare ResearchThis layer was derived from three existing data layers: the Land Cover Database 2 (LCDB2) (MfE 2002); the Land Use Map (LUM) from the Land Use Carbon Analysis System (MfE 2008; Dymond et al. 2012); and EcoSat Forests (Shepherd et al. 2002). Indigenous forest classes from EcoSat Forests were combined with classes from LCDB2 to form basic ecosystems...Created 3 May 2018 • Updated 3 March 2025 -
LENZ - Soil drainage
Manaaki Whenua – Landcare ResearchDrainage 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 https://data.mfe.govt.nz/layers/?q=LENZ for to access these layers). This data layer described the internal drainage of soils. The classification used in...Created 3 May 2018 • Updated 3 March 2025 -
Vegetative Cover Map of New Zealand
Manaaki Whenua – Landcare ResearchThe 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...Created 3 May 2018 • Updated 3 March 2025 -
FSL Soil Drainage Class
Manaaki Whenua – Landcare ResearchThe 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...Created 3 May 2018 • Updated 3 March 2025 -
S-map Soil Classification (soilorder) Aug 2024
Manaaki Whenua – Landcare ResearchNZSC Order is the first level of the NZ soil classification (Hewitt, 2010). This layer is a "dissolved" representation of the NZSC soil order attribute for S-map, where neighbouring S-map polygons have been combined if they have the same value of the attribute. Refer to document Smap Data Dictionary Dissolved Layers.pdf at...Created 3 September 2024 • Updated 3 March 2025 -
Potential Vegetation of New Zealand
Manaaki Whenua – Landcare ResearchNew 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,...Created 3 May 2018 • Updated 3 March 2025 -

S-map Soil Drainage Aug 2024
Manaaki Whenua – Landcare ResearchSoil drainage is a relatively simple classification of the soil profile that describes the likelihood of seasonal wetness (Webb & Lilburne 2011). It is based on the occurrence within specific depths of redox segregation and low chroma colours indicative of waterlogging and reduction (Milne et al. 1995). This layer is a "dissolved" representation of...Created 3 September 2024 • Updated 3 March 2025 -
