February 2018

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.

Australian Museum Award!

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.

2018

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

December

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.

October

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.

August and September

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.

July 2017

Lots of good things are happening at our ongoing regeneration site between the BMX track and Waratah Street. The BMCC  Bush Regeneration Team has been working in there, and we can really see the difference, especially along the walking track. So thank you to them for this support.  BMCC’s Bushlands Operation Co-Ordinator has also arranged for a bush regeneration contractor to remove another large stand of Privet on this site, and we thoroughly approve of that work too. The plan is to have the contractors working on the site on a regular basis, removing a section of weed each time. The long-term objective is to entirely remove this wall of weeds from the upper catchment of Lawson Creek and restore the native bush.

The bushcare group worked on the newly cleared area on Sunday 16/07/17 and we should be able to control any weed regrowth. Good native plants are starting to establish themselves there. All of this work represents excellent co-ordination and targeting of professional and volunteer work-time and skills and we have reason to suspect that our BMCC Bushcare Officer may have had a role in facilitating this process.

The Lawson Butterfly Project will be commencing in September.

June 2017

In May and June the group has been working under the power lines to the west of Lawson oval, where there is some quite nice bushland : treated Turkey Rhubarb, Blackberry, Furmitory and Passionfruit.

We have been invited to participate in a special local regeneration project. Michael Hensen, Environmental Scientist, BMCC, has obtained funding to restore a butterfly hilltopping site in Lawson. This should be interesting and we are going to devote a few work sessions to the project. Other community groups will also be involved.

April 2017 bushcare news

The BMCC bush regeneration team has just finished some much welcomed work in the  swamp at the headwaters of Lawson Creek, just south of Waratah Street. This is a demanding area to work in and it’s great to have them in there.  Privet and Blackberry were amongst the targets. Perhaps they got some Salix (Pussy Willow) too. This area has received professional contract bush regeneration work over the years, the last recorded time being in approximately 2008. Probably the Urban Runoff Control Program funded some work in there too c.2000, so it’s good to have this previous work supported by the Council regen team.Thanks also to our Bushcare Officer for liaising with the regen team and getting this work done.
