Abstract: |
The 1840 ‘Land Cover Database’ is a data layer which is an approximation of land cover as at 1840 at a regional scale. |
Statement: |
This data set is an approximation of the land cover types (as used in the ‘official’ LCDB) at the time of European settlement (i.e. prior to conversion of native vegetation to agricultural, urban or exotic forestry land cover). The data set is an exhaustive and mutually exclusive classification derived from a reconstruction of vegetation cover as of 1840 (based on landform/ soil types/ bioclimatic zone, early settler accounts, early air photograph data, and current vegetation cover).
The 1840 Land Cover Database is a classification of land cover types separated into 7 classes derived from the Regional Indigenous Vegetation Inventory (Leathwick et al. 1995) F_1840_Vegetation (1:250,000), refer to RIVI metadata (WRC Document # 881138).
Data fields are grid reference, area (m2), and land cover class.
The seven cover classes are: Indigenous forest, Scrubland, Coastal dune vegetation, Inland water, Inland wetland, Rock or gravel, Tussock grassland.
Additional LCDB cover classes (Coastal sand, Bare ground, and Coastal wetland) are likely to have been present in 1840. However, because of the scale at which the 1840 map was produced, and the difficulties with reconstructing coastal wetlands (subject to change over short time periods) these classes are not delineated on the 1840 ‘LCDB’.
Definitions of each class are not available, however, it is assumed that all vegetation was indigenous at that time, and therefore scrubland is likely to cover indigenous vegetation e.g. manuka scrub only (cf current LCDB shrubland may include gorse, woolly nightshade or other exotic communities). Descriptions of the source vegetation types are available in Leathwick, J.R., Clarkson, B.D. and Whaley, P.T. 1995: Vegetation of the Waikato Region: Current and Historical Perspectives. Landcare Research Contract Report: LC9596/022. Maanaki Whenua – Landcare Research, Hamilton (WRC Document # 2812623).
The contracted minimum-mapping unit is 25 hectares (although some smaller units have been retained in the dataset where they were easy to distinguish). The positional accuracy and target classification accuracy for the RIVI 1840 is unknown and unable to be tested, as the map is a reconstruction.

General Notes:
The Regional Indigenous Vegetation Inventory (RIVI) is an alternative dataset for those particularly interested in indigenous vegetation types (current and historic coverage). See metadata for the RIVI (DOCS# 881138) for limitations to the use of that dataset.

Statement: |
Refer to RIVI metadata (WRC Document #881138) for acquisition methods of the source imagery. 1840 vegetation was reconstructed from unpublished maps, early aerial photographs, and the accounts of settlers. The methodology and results are documented in:
Leathwick, J.R., Clarkson, B.D. and Whaley, P.T. 1995: Vegetation of the Waikato Region: Current and Historical Perspectives. Landcare Research Contract Report: LC9596/022. Maanaki Whenua – Landcare Research, Hamilton (WRC Document # 2812623).

Other Information: |
The accuracy of the attribute data has not been verified. Area is generated automatically based on the digital polygon. Class is applied as per the table above. Shapes of the aggregated polygon have been visually compared with the 1840 classes to ensure accurate merging and classification.
Complete coverage of land, inland water, and coastal dune and wetland space in the Waikato Region. Harbours or portions thereof, outside the regional coastline boundary are not included.
Data used to generate the original (RIVI) shapes varies (i.e. early maps of various quality, soil maps, early air photographs). Therefore the boundaries and classification have not been generated from consistent methods. |
