Rehabilitation post fire

By Sandy Benson

Rehabilitation following prescribed fire suppression activities in Mount Riverview

After a recent prescribed burn on a Mount Riverview Bushcare site, rehabilitation of several constructed fire containment lines has been completed. These containment lines or fire breaks are used to protect surrounding bushland that are not registered to be burnt. Unfortunately, fire breaks have the potential to create erosion unless rehabilitated by stabilising the exposed soil.

The aim of this rehabilitation project is to prevent soil erosion and reduce the likelihood of the fire breaks becoming new walking or bike tracks. The fire breaks were covered with a base of jute mesh, then native on-site mulch including branches, leaf litter and rocks were spread over the top to blend in with the natural landscape. The Mount Riverview site will be monitored to ensure that the fire break is not visible or subject to erosion due to extreme weather conditions.

Post fire can offer favourable opportunities for weed control and management or can have a negative effect on a site, dependant on the intensity of the burn. In this case, as the fire was a controled burn and not a wildfire, the intensity was low or considered a cool burn. Post cool burns, most plants can re-shoot from their stems due to thick bark that protects the buds from damaging heat, so they can recover rapidly after a fire. Native plants hold their seeds in thick woody fruits or capsules, where they are protected from fire, the fire assists in opening the capsules. When the seeds fall to the ground they land in the ash bed, which is high in the nutrients needed for strong seedling growth. This aids the natural regeneration of the bushland.

Post-fire risks and opportunities

  • Improved access: provides opportunities to control weeds that were difficult to access.
  • Mature plants are killed or reduced in number.
  • Exhausting weed seeds in situ if consistently followed up with weed removal: manual removal or spraying of seedlings before maturity and seed setting can exhaust or reduce the weed seed bank.
  • Mass establishment: fire can be particularly favourable for weed species and a substantial increase of the initial infestation may occur post fire.
  • Cause erosion and subsequent sedimentation of creeks and wetlands.

Post fire weed treatment can be particularly effective and presents an opportunity for a local reduction of weeds. The Mount Riverview Bushcare group has been involved in post fire weeding and monitoring of the site. Access to areas infested with weeds post fire has been greatly increased and has allowed Bushcarers to reduce the number of weeds in the burnt areas.

Blue Mountains Bushcare welcomes new Bushcare Officer Steve Fleischmann

Integral to Bushcare is the strength of our community engagement and leadership, and we are delighted to introduce you to our new Bushcare Officer, Steve Fleischmann. Steve will be taking over Lyndal’s Bushcare groups and the Remote Program.

Steve has hit the ground running, and you may have already met him on site with our experienced Bushcare Officers.

Steve has extensive experience in bush regeneration projects. In the 90s he worked in Sydney’s Northern Beaches. After completing Certificate III in Conservation Land Management, he enjoyed working on a variety of bushland management projects across the Mountains, Western and South Western Sydney, in environmental sustainability education, and running an organic farm with refugees. He has also been raising two children.

Steve spends as much spare time as he can playing music, going canyoning or taking his kids into the local bushland areas. Blue Mountains City Council Bushcare Team Leader, Sandy Benson, said that Steve’s experience and his friendly attitude make him a brilliant addition to the Bushcare team.

Please welcome Steve to the Bushcare family.

Its time to remove the heads from your Agapanthus

Well its that time of year when the seed heads of Agapanthus are forming. The plants by themselves are not too bad as they hold the soil together so in some instances where the soil is unstable they are best left and deheaded.

On the other hand the seed can travel down creeks into the areas of bushland and take root on creekbanks and unusual places like gutters. The root fragments can be spread in the movement of soil and dumped plants can survive for years and take root where they are left.

Agapanthus are tough plants so they have been used extensively on edges and next to drains. All of these drains and run off lead into the bushland. So if we remove the seeds the plants can not move into the surrounding bushland.

The students at Megalong Valley Public School have produced a short film creating real change in their community shining a light on the critically endangered species Callistemon megalongensis in the Megalong Valley.

The students of Megalong Public School are keen Guulong Landcarers and want to spread the message about protecting both threatened species and caring for their local native environment. With support from local legend David King a Gundungurra man, Landcare, Bushcare and the Greater Sydney Landcare Network they have recently been presented an exceptional achievement award by Paul Vale, Blue Mountains Bushcare Network and committee member of GSLN.

The seven student school is a tribute to leadership and sustainability, and have shot, edited and developed their own film with professional assistance, to create an engaging and entertaining film highlighting conservation values of the Callistemon megalongensis in the Megalong Valley.

The Megalong Valley bottlebrush is a critically endangered species, restricted to a small range of just 10kms around the Megalong Public School, with only 200 plants identified.

According to the Office of Environment and Heritage, the small total population size makes this species highly vulnerable to the following threatening processes including:

  • High frequency fire, as well as intense hot fires that burn the peat layers of the swamp habitat. Also lack of fire may result in excessive weedy scrub development.
  • Road upgrades and maintenance of road verges, powerlines and water mains where this species occurs can cause direct damage to plants as well as erosion, sedimentation, weed invasion and other forms of degradation to the habitat of this species.
  • Weed invasion, particularly Japanese honeysuckle and blackberry.
  • Altered swamp hydrology.
  • Grazing by cattle and horses.
  • Horse riding and recreational vehicular use (recreational 4WDs and trail bikes) along informal tracks intersecting swamps containing this species.
  • Erosion caused by pig diggings and wallows damages habitat.

Changes to the Noxious Weeds Act 1993


From the 1st of July 2017 the NSW Government has replaced the Noxious Weeds Act 1993 with the Biosecurity Act 2015. Under the Biosecurity Act 2015, the Blue Mountains City Council, as the Local Control Authority, has a legal obligation to manage the biosecurity risk posed or likely to be posed by reducing the impacts of Priority Weeds.


Biosecurity refers to the protection of native plant communities; reducing the risk to human health: and the risk to agricultural production, from invasive weeds.


Under the Biosecurity Act, landowners have a responsibility to control the risk that Priority Weeds on their property pose to neighbouring bushland and properties.

Residents will see a change in the terminology used, for example, the term Noxious Weed will be replaced with Priority Weeds or Biosecurity Matter, and weed notices/orders will be issued as Biosecurity Directions under the Biosecurity Act. There are also some changes target invasive plants identified as Priority Weeds compared to previous Noxious Weeds lists.

Therefore the Noxious Weeds Classification of individual weeds is no longer correct.

Will the Biosecurity Act change the way Council manages weeds on private property?

No. Council’s Urban Weeds Program and the process for inspecting private properties for invasive weeds will continue unchanged. Council will also maintain its current approach to education and enforcement relating to invasive weeds. Council will maintain the current process for issuing Weed Control Notices. The main differences will be the terminology used and that Orders will be issued under the Biosecurity Act. They will be known as Biosecurity Directions.
