Habitat complexity

This transect records observations of benthic habitat complexity on a scale of 0 to 5, based on the methodology proposed in Wilson et al. (2007) and described in Darling et al. (2017) and Gurney and Darling (2017) (Appendix 2).

To enter a habitat complexity transect, you will need to provide a transect number, the surveyed transect length (m), and the interval between complexity observations (m). E.g. assessing complexity 5 m can be entered at ‘5 m’ in the “Interval size” box.

Enter the habitat complexity score at each interval at the bottom of the page. You must have as many rows of observations as you do intervals in the transect length.


Use the ‘tab’ keys to move across the interval and habitat complexity score columns. At the end of the row, press Enter to create a blank row to add the next complexity observation. If the same habitat complexity is observed at the next interval, press the ‘Tab’ key at the end of the row to duplicate the row.
