In the recently released report Lawson and Cataract Creeks received ‘Fair’ ratings and the rest of the Erskine Creek catchment was rated “Good” to “Excellent”! This is an improvement for Lawson Creek, which only got a “Poor” last year. We had detected an improvement when we did macroinvertebrate sampling last October and it looks like this has held up into 2018. The report should be posted on https://www.bmcc.nsw.gov.au/waterquality soon.
This session the group worked at the eastern end of the unformed Waratah Street section, treating Turkey Rhubarb, Privet, Japanese Honeysuckle and Broom. It would seem that we have Sugar Gliders in the area, so that’s great! This area just used to be a forest of Privet, so removal of it may have enhanced the glider’s habitat and particularly feeding opportunities.
In June we continued with our regeneration site work near Waratah Street. The Leptospermum polygalifoliums (tea-trees) and native grasses ares doing well here and the Privet is under control.
We had an avian visitor, a Grey Fantail, Rhipidura albiscapa. S/he was constantly buzzing us (inquisitive?!), and also snatching insects in this sunny spot. Previously about the only bird life seen in this area were Bulbuls feeding on Privet seed. An Eastern yellow robin (Eopsaltria australis) stopped to admire our work…and to have a feed too!

A recce done on Friday 22/6/18 reveals that it is possible to walk through the wall of weeds that runs adjacent to the southern edge of Waratah Street, with a bit of bending, ducking and scrambling. Privet and Blackberry dominate. An occasional good fern and wattle were also found. We might start some work in there soon.
In May the Bushcare group continued with the work commenced in April, treating weeds in the regeneration site adjacent to Waratah Street. Our Bushcare Officer is pleased with the progress in this area and further expansion of the work here is being considered, with a “recce” planned.
It’s also good to hear that the BMCC Bush Regeneration Team has been working along Lawson Creek in the carpark area, and that contractors have been working near the RMS detention basin and through the swamp on Lawson Creek.

This month we resumed work on our site immediately adjacent to the unformed section of Waratah Street. This area, normally quite damp, is now drying out a bit, due to the decreased rainfall of the last year. The natural ferns are struggling and the weeds Deadly Nightshade, Privet and Montbretia are doing well. We spent the time consolidating recovered natural bushland areas and weeding around remnant areas of good bushland. The same area is depicted in the post of July, 2017. A challenging site!
A hot day saw us working in and around the mid-stream Lawson swamp, opposite the oval. Weeds included Blackberry, Privet, Arum lily, Montbretia and Japanese honeysuckle. Sections of this swamp are in nice condition but quite a bit of it still needs a lot of help.

Another hot day saw us working between Lawson oval and the rather dryish upper section of Lawson swamp, treating Privet, Blackberry, Arum Lily, Montbretia and Japanese Honeysuckle. Lawson Creek is only about half its normal width: mud flats are exposed. Hopefully the heavy rain around the upper Mountains on Monday evening of 19/2 evening extended down to Lawson.
On a very hot day the group removed juvenile Privet, Turkey Rhubarb, Buttercup, flowering Montbretia and invasive Strawberry from the creek riparian zone opposite the playing fields.
The prestigious Australian Museum reckons we do a good job! We enjoy working with Gregory and the team there.
Congratulations to all those involved with Lawson StreamWatch over the years.
