Blackheath Botanical Beauty

By Karen Hising and the members of the Blackheath Centenary Reserve Bushcare Group

Blackheath Centenary Reserve is a small area of bushland of just over two hectares, which lies between Brentwood Avenue and Cleopatra Street, Blackheath.  The site was originally retained by the Department of Education.  However, in 1985, at the close of celebrations for the Blackheath Village and School Centenary, the Organising Committee had suggested this site as a natural bushland reserve.  Acting through the Mayor, Mr Peter Quirk, the Committee applied to the State Government for the site to be set aside for this purpose.  This was achieved in May 1987, the Reserve thus being under Council management.

Although totally surrounded by houses and streets and only a small area, the Reserve contains a good biodiversity of native plants indicative of ridgetop vegetation. Much of this type of vegetation has been removed over time for housing development, so it is an important remnant in the area.

Thanks to Joyce Brister and others, a Bushcare Group was established in 1987, making it the oldest group operating in the Blue Mountains. 

Historically, the site had been affected by serious infestations of Gorse and Broom, a number of mature Pines and a range of other weeds, as well as dumping, encroachment and illegal vehicle access.

With grant funding, more than twenty large Pine trees were felled, which greatly improved the understorey biodiversity.  In 2011, with assistance from local RFS Brigades, Council conducted a hazard reduction burn in one part of the site for fire mitigation purposes.  However, the planned burn also provided the opportunity to reduce the Gorse and Broom seedbank in the soil (stimulating their growth, allowing many seedlings to die out naturally and others to be handweeded in the following years).  Being an “island” site, where biodiversity recruitment is limited, the burn also stimulated the growth of a range of native plant species.

Many of the other problems have now been controlled and although the Reserve continues to require ongoing maintenance weeding and monitoring, we have been very pleased with the wonderful regeneration that has occurred.

Although landlocked between housing, the Reserve is also an important area of habitat for some local native wildlife, particularly birds.  Local residents often enjoy walking through the Reserve too!  And despite its small size, the site always surprises us with some beautiful plant species.  Whilst there are a number of spectacular flowering Waratahs in the Reserve, of particular interest are the Orchids.  We are fortunate to have some dedicated Bushcare Group members, who often monitor the Reserve and report and document their amazing finds.  Some photos are noted below, but there are more in the Group’s webpage:  https://centenaryreserve.bushcarebluemountains.org.au/photos/ and in the blog.

Blackheath Centenary Reserve proves that despite being small in size and surrounded by development, with lots of edges and some tracks, it is still important habitat for local native wildlife and plants.

The following article from “The Conversation” is an interesting read in that regard.

Grant awarded for Turtle Habitat Construction

Glenbrook Lagoon has been awarded a $5000 grant to construct an artificial floating turtle habitat in Glenbrook Lagoon, as part of a pilot program in the area. Such structures aim to reduce turtle loss by providing safe habitat for laying eggs, away from the shoreline and predators.

Dr Ricky Spencer and a team of PhD students from UWS in partnership with Council are working to provide a habitat for turtles — and possibly structures for yabbies and fish underneath. See the article written by the Gazette with Dr Ricky Spencer discussing Turtle habitat in the Blue Mountains, https://www.bluemountainsgazette.com.au/story/4320357/shell-shocked-turtle-concerns-during-nesting-season/

Bushcare volunteers are invitied to come along and join us construct the floating Turtle Habitat and learn how these systems operate on 14th May, 2019 at Glenbrook Lagoon. To book, click on the link below.

The UWS is asking Sydneysiders to help with their research on Turtles, by logging on to  TurtleSAT to document any sightings. This project is gathering data on where the turtles are, and what they require to thrive, to help manage populations into the future. There is an app you can add to your phone that is easy to use.

For more information on the Turtle Habitat project, contact Geoffrey Smith, Program Leader for Healthy Waterways, on 4780 5751 or gsmith@bmcc.nsw.gov.au

Bio-filtration System in Action at Silvermist

A Bio-filtration system is as the name suggests is a living filter, employing microbes and wetland plants, gravel and sands, to filter the stormwater and urban runoff. Pollutants, increased nutrients, sediments and faecal coliforms in the stormwater negatively impact the health of the natural creek system, contributing to weed growth and exacerbate existing problems.

The filter consists of three layers underneath; gravel, sand and a carbon source with piping underneath to let the filtered water flow out. The native plants at the surface also play a role absorbing contaminants and nutrients and slowing the water flows down for absorption.

This image has an empty alt attribute; its file name is resized_4546.jpgSlowing the water down ensures it can soak into the filters and surrounding soil, this recharging of groundwater mimics the natural hydrology and moderates the rapid flow of stormwater from the hard, impervious surfaces above. This is an important balance to ensure it captures as much pollutants as possible.

 

The water will flow out of this pipe quickly so to slow it down rocks are concreted onto the ramp to diffuse water. The sediment basin does this too, reducing velocity and catching sediment that precipitate as a result of the slack water. It is important to catch this sediment where it can be cleaned out, before it continues downstream.

From the ramp there is a pool made from large boulders followed by a ramp of rocks to ensure there is oxygen added to the water and to slow the flow down. This picture shows the gradient is only very slight to slow the water down.

This image has an empty alt attribute; its file name is SIZE-_4544.jpg

Rock sills are built to stabilise the gradient, further reducing velocity and maximising water penetration.

Riffle zones made from smaller rocks help to oxygenate the water by increasing its exposure to the air, aiding oxygen absorption.

Most endemic species prefer low nutrients, whilst invasive weedy species enjoy the high nutrient urban runoff, so it is important to remove the excess nutrients from the stormwater before it enters the natural environment.

Blechnum ferns were used on the edges as the root systems of these naturally occurring ferns have excellent holding capacity and appear in the creek line systems sounding this site.

The steps involved for this project to happen include:

  •  the woody weeds were removed by contractors
  • a machine to shape the bed and for large rock placement
  • geotextile fabric and gravel, sand and piping added then jute mat and coir logs added below  the structure
  • rocks sills built and planting in and around structure

Each site is different, with different constraints as well as possibilities. Site assessment and careful design are important when planning a similar project. The fundamentals are pretty standard from site to site, and can be applied to most situations.
