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.

What better way to start a new year than with a good piccy. Thanks to our bushcare officer for getting this great snap.

At our regular work session on Sunday 17/12 we worked around the golf course detention basin and then along our planted riparian corridor, treating blackberry, montbretia, japanese honeysuckle, creeping buttercup, broom and turkey rhubarb. The BMCC bush regeneration team has done some welcome remediation work (brush-matting) along the eroded Lawson Creek banks above Adelina Falls.
With the welcome rain having washed out a few sessions we had a catch-up session this am, Friday, December 1. The area to the west of the oval, the fine swamp under the power lines, was treated for blackberry, formosan lily, passion fruit vine and turkey thubarb……BIG turkey rhubarb! Hopefully this area is now predominantly rid of blackberry. The normal December session on the third Sunday will also be held, weather permitting.

A welcome wash-out for the scheduled October session. Nice rain. We will have a catch-up session on October 25/10 to target some seeding Broom. The very good news is that Streamwatch macroinvertebrate testing on 13/10/17 revealed lots of Mayfly nymphs and other bugs in Lawson Creek, downstream of the swamp. This nymph is very sensitive and requires very good water quality so their presence is pleasing. This is a big improvement on the last series of testing.

We continued working around the detention basin located near the former golf course. Weeds here include Broom, Blackberry, Privet, Lily, Indigofera sp. (planted but not native to the area) and Japanese Honeysuckle. Generally the swamp here is doing well.
The Lawson Butterfly project is picking up some planning momentum and looks likely to spring into action with a pilot project later this year, with the main event taking place next year. “Community involvement” is a major theme.
