Thursday last week the Mt Gravatt PCYC Bush Restorers joined us at Roly Chapman Bushcare to clear weed regrowth and plant 160 vines, grasses and shrubs to create an edge seal along the primary school fence.

Restoration work in Roly Chapman is part of the Mimosa Creek Precinct
Landscape Plan to link Mt Gravatt Conservation Reserve with Bulimba Creek.

An edge seal is a barrier to protect natural bushland from weed invasion. For example, reduce the feathery seeds from the yellow flowering Flatweed (Catsear) Hypochaeris radicata blowing over from the school oval.

Clearing weed regrowth was required to prepare for planting. I started by explaining the Bradley Method of regeneration:

  • Word from strength – work from least weed infected to worst infected;

    Flatweed - Hypochoeris radicata - weeders

    Expert Weed Eradicators

  • Minimise soil disturbance to maintain the diverse life in the soil

The Bradley Method does require skilled workers. So it was a real pleasure to work with two expert Weed Eradicators to remove the deep-rooted Flatweed. The ground was soft from recent rain so with carefully pulling the the weed vertically allowed removal roots and all with minimal disturbance to soil.

Plants were selected from species already found in Roly Chapman Bushland Reserve. Vines Hardenbergia violacea and Smilax australis are a good way to hid a chain-wire fence and provide food for butterfly caterpillar and fruit for fruit eating birds. Growing to 3 metres with a 2 metre spread and reddish green foliage the Coffee Bush Breynia oblongifolia is an attractive garden feeding butterfly caterpillars and decorative Green Jewel Bugs Lampromicra senator.

Grasses like Barbed Wire Grass Cymbopogon refractus and Kangaroo Grass Themeda australis will create an edge seal below the shrubs and feed seed eating birds. Sedges and rushes like Tall Sedge Carex appressa and Common Rush Juncus usitatus thrive along the fence line where run off from the school oval creates a damp habitat most of the year.

Mulch filter

 

Sunday 10th April, a lovely sunny morning and new volunteers join the team for the second community working bee of the year.

First step, before it gets too hot, is working along the fence between the reserve and Upper Mt Gravatt SS oval. One group continued clearing weeds along the fence line while the other group starting moving the mulch delivered by BCC Habitat Brisbane last month, staking plants and installing a timber edge to contain mulch to create a break between the oval and the bush. The 20cm thick layer of mulch will act to slow the large volume of  water runoff from the large area of the school oval. This allows the water to soak in rather than just run off and also acts as a weed seed filter protecting the bush.

Kate demonstrates cut and dab

Only partially complete this mulch filter is already working to stop weed regrowth and promote growth of the planted melaleucas (doubled in size) and the clumps of Common Rush Juncus usitatus

Kate Flink, our Habitat Brisbane Officer, also joined us for the morning. Besides helping to move heavy barrow loads of mulch she gave a demonstration on herbicide application using the cut and dab method.  This is an ideal way to deal with thickets of Easter Cassia Senna pendula var. glabrata and Small Leaved Privet Ligustrum sinense that have infested this area.

Morning tea for team

Hard work is rewarded with morning tea

At the end of a busy morning we were very grateful for our morning tea (especially the raspberry slice) prepared and brought to us by Trevor and Carol.  Thank you to all the volunteers and especially Kate for her help, encouragement and invaluable information.
