Map usage: Drag and scroll on the map to move and zoom in on areas of interest, hover on the site circles to see more information, hover over each outlined area to see Whaitua (main river catchments), use the selection box on the top left of the map ( ) to subset table data to that area.

Table usage: Click on sites in the table to highlight them on the map, and click on headers or the arrows next to them () to sort the data by that column – holding the shift key allows sorting over multiple columns.

Bulk density

Bulk density is a measure of soil density. A high bulk density indicates a compacted or dense soil. Movement of water and air through soil pores is reduced in compacted soils. High soil bulk density can restrict root growth and adversely affect plant growth. There is also potential for increased run-off and nutrient loss to surface waters in compacted soils. The target range is ‘Loose’ to ‘Compact’, see benchmarking for more information.
