  • Sediment Retained

    Manaaki Whenua – Landcare Research
    This layer depicts estimated sediment/soil retention across New Zealand and was created using the NZeem erosion model. Sediment retained is defined as the difference between...
  • GHG Fluxes (Greenhouse Gases)

    Manaaki Whenua – Landcare Research
    The current New Zealand greenhouse gas inventory derives implied emission factors that vary between animal types (Ministry for the Environment, 2010). The spatial distribution...
  • Sediment Lost

    Manaaki Whenua – Landcare Research
    This layer depicts estimated sediment/soil loss across New Zealand and was created using the NZeem erosion model. Erosion control is defined as the prevention of soil loss by an...
  • Water Yield

    Manaaki Whenua – Landcare Research
    This layer represents the net supply of water remaining after evapo-transpiration losses (mm/yr) as an indicator of water- flow regulation. Although this is a simplified view...
  • Nitrate Leaching

    Manaaki Whenua – Landcare Research
    Nitrogen leaching was estimated using OVERSEER farm nutrient budgeting software version 5.4 (Ministry of Agriculture and Forestry et al., 2011) with a modifier to account for...
  • New Zealand Potential Vegetation (Grid version)

    Manaaki Whenua – Landcare Research
    New Zealand's potential forest composition was predicted from regressions relating the distributions of major canopy tree species to environment. Environmental variables, chosen...
