The Bushcare Group acknowledges the terrible bushfires in the Blue Mountains and Australia that have occurred since spring 2019, and their dramatic community and ecological impacts. The Erskine Creek catchment, into which Lawson Creek flows, is part of Blue Mountains National Park and the World Heritage Area, and has been badly affected. This is an excerpt from a Blue Conservation Society members’ e-brief:
78% of the GBMWHA Burned
As of Monday 13 January, 78% of the Greater Blue Mountains World Heritage Area (GBMWHA) has been burnt, and an estimated 140 million native animals have been impacted.
This has been calculated by Peter Smith using the MapInfo program and Fires Near Me to obtain mapping of burnt areas.
These are preliminary estimates and will be updated when the final fire maps are available from NSW Department of Planning, Industry and Environment after the fire season.
The burnt area of each of the eight reserves of the GBMWHA has been calculated.
Peter has also calculated the number of animals impacted by multiplying likely densities of animals* in unburnt habitat by the number of hectares burnt.
The densities are very rough estimates, but are the best available for NSW.
In any case, it is clear that huge numbers of animals have been impacted and most of them have died as a result of the drought, the fires and the shortage of food, water and shelter after the fires.
The unprecedented scale of the fires, leaving few unburnt refuges from which to recolonise, makes the recovery of the fauna highly problematic.

Today’s work session was cancelled as it was too smoky, uncomfortable and an adverse impact on health.
Our Bushcare Officer and Rob have provided the following information about the assessment of air quality in the Blue Mountains: https://www.epa.nsw.gov.au/news/media-releases/2019/epamedia190514-air-quality-monitoring-project-in-blue-mountains-kicks-off

We continued working in our Waratah Street restoration area. The clumps of Privet are steadily being reduced and the Blackberry in the swamp is nearly gone. Satisfying work! Getting a bit dry now but the creek is keeping up a healthy trickle. Welcome to new member Max.
At these sessions we continued work in the regeneration area and swamp near Waratah Street. The Privet and Blackberry are gradually diminishing…gradually! Nice to have new member Helen along in October. Our Duke Of Edinburgh Award student is hoping to be back with us soon for another stint of Privet lopping, after a major river trip. We look forward to hearing about it!
Work continued in our regeneration area around the headwaters of Lawson Creek. Slow but steady progress here! The regenerating flora is now heading towards two metres in height. Lots of privet bit the dust, courtesy of our D of E placement student, who is really getting the hang of bushcare practice! Progress in the swamp is good, and the actual basin is now moving towards a weed free status…but still plenty to do around the edge.
