Research concerning North Head

1. Research after fire

This area was not burned but was "thinned" by removing tea tree plants.

This is an area before a fire went through.

After the fire regeneration was monitored and compared with thinned areas.

6. Surveys to evaluate the impacts of fire - comparing ground surveys with Unmanned Aerial Vehicle surveys Authors: Geoff Lambert, Judy Lambert, Jeremy Randle Paper presented to the Ecological Society in Brisbane in November 2018 This paper examined the questions of ...... Can ESBS be restored by fire? Can we compare Ground-based quadrat surveys of 1% of the site with Aerial Surveys of the same area? Can we extrapolate to the entire site from the survey of 1%? The conclusions were that ... * Plant species were identifiable from drone imagery by inspection & possibly by training the image analysis software; * Plant numbers are harder to measure but coverage should be measureable, with software; * Quadrats seem to have captured a representative mix of species * We can extrapolate from this to the whole site
