Success Stories

Local papers often features stories written and submitted by the PHBG.

We are always on the look for good news stories about people taking care of their patch, or helping others get on top of their weeds or feral animals.

We know many of you quietly get on with the job, but letting others know about your work can help motivate others that might not know where to start. Tips for overcoming common challenges are invaluable, especially for landholders new to the area.

Please contact Teele if you are aware of any local success stories. Email or phone 0474 242 223.

Weed ID and Advice Workshop proves popular

So popular was the Weed ID and Advice Workshop, two sessions were run instead of just the one that had been originally planned.

Over 70 people attended across the two sessions, with a total of 150 weed samples brought in to identify and discuss.

The PHBG welcomed back weed experts Greg Keighery, Order of Australia recipient, and Principal Ecologist Andrew Mitchell to host the workshops.

The workshop was informative and interactive with many attendees providing feedback that the workshops increased their knowledge of weed identification and control.

Attendee, Ms Mcarthur wrote after the workshop, ‘Thank you so much for organising it, such knowledgeable presenters - so much to learn!’

Another attendee wrote, ‘Very informative and such a mountain of knowledge. Many thanks to all involved’.

A large number of Shire of Serpentine Jarrahdale grounds crew attended and the officers had many questions about the plants they come across in their day to day work.

All attendees received the perfect companion to weed ID and control in the form of the Southern Weeds and their Control booklet. Correct identification of weeds is the first step in effective control. The take home resource provided at the workshop described both physical and chemical control options.

Many common weeds made an appearance on the day with lots of different samples from the oxalis, erodium and sow thistle groups. There were also many unfamiliar samples, like the asparagus sample that was declared and highly invasive, black flags with their tiny corms ready to spread and the growing threat from Euphorbia which is starting to become more common on roadsides but can cause serious allergic reactions. There was even a plant that the experts could identify and it was taken home for further study.

‘The first step in weed control is correct identification - knowing which weed you’re dealing with helps direct control to the most effective method. At our workshop over 80% of attendees said they would be more confident identifying weeds going forward,’ said weed education officer, Teele Hooper-Worrell.

‘The intention of hosting our workshops is to upskill our community in weed identification, leading to more successful weed control. It’s a great feeling seeing how popular and successful the workshop was and the PHBG look forward to hosting more workshops like this one in 2021,’ said Ms Hooper-Worrell.

Communities, Collaboration and Control

A collaboration between the Department of Biodiversity, Conservation and Attractions (DBCA) and the Peel Harvey Biosecurity Group (PHBG) led to five days of cotton bush removal in the Serpentine National Park.

The Serpentine National Park is a popular site with locals and attracts national and international tourists to the Shire of Serpentine Jarrahdale. Cotton bush is a problem weed in the National Park, particularly around the heritage-listed Spencer’s Cottage.

Over the years the PHBG has received multiple reports from the members of the public concerned about the cotton bush in the National Park. DBCA has initiated control works in the past; however, it is an ongoing battle with plants germinating from a large seed bank.

The PHBG had the opportunity to intensify weed control efforts in the Serpentine National Park through the Australian Government’s Community Environment Grant Program which allowed it to engage an Ecojobs team to remove cotton bush.

Senior park ranger, Paul Tholen, expressed that cooperation between the different stakeholders will no doubt lead to improved social and environmental outcomes in the National Park.

“This activity has the potential to make a big difference in cotton bush control in the areas surrounding the recreation and picnic facilities.

“Thanks to everyone involved for such a sterling effort,” Mr Tholen said.

According to Teele Hooper-Worrell, weed education officer for the PHBG, challenges presented by coronavirus were also overcome.

“Staff from DBCA’s Parks and Wildlife Services and Ecojobs were able to maintain social distancing requirements and still remove cotton bush.

“It’s always a great feeling when the biosecurity group can take community reports into collaboration across tenure with the result being cotton bush removal,” said Ms Hooper-Worrell.

Physical removal of the cotton bush plants was done by removing the seed pods and then pulling out the plants using tree poppers provided by the PHBG. The seeds were then placed in plastic bags for solarisation (which destroys the seed) and disposal.

The project’s focus moves now to the installation of interpretive signage to raise awareness of the project’s achievements. The signs will increase public awareness of cotton bush and the importance of its ongoing control in the Park, as well as across the broader landscape.

Parklands community effort protects Marlee Reserve.

In response to community reports of fox activity in the area surrounding Marlee Reserve, the Peel Harvey Biosecurity Group coordinated the placement of 13 fox traps on private property.

The thirteen traps were delivered and set up in time to support a trapping program centred on the Marlee Reserve run by the City of Mandurah.

Marlee Reserve is recognised as one of the most important conservation reserves in Mandurah. The reserve is home to a wide range of species, including the Brush-tailed phascogale, quenda, and the long-necked turtle.

Efforts by community members and the PHBG extended the control area to over 550 hectares across the Parklands area with the program resulting in the removal of two lactating foxes and three feral cats.

The fox traps were delivered prior to the trapping program commenced to allow them to settle into the environment. Private landholders wired the traps open and used lures to increase the likelihood of success.

“Foxes can be trap-shy,” said Anneliese Bone, feral animal officer, for the PHBG.

“We have heard of a landholder trapping a fox within an hour of setting up a cage trap but generally the fox will check the cage a few times before entering.

“To entice the fox to take a look in the cage, a lure is used. A good example of a lure is cat food.

“The process can take a few weeks or even longer if you are trying to trap a mature fox.”

The PHBG is keen to set up similar coordinated community programs in 2020 for foxes and other declared pests.

Caroline Knight, Deputy Mayor of the City of Mandurah, is an advocate of collaborative efforts.

“Coordination between the City of Mandurah, the Peel Harvey Biosecurity Group and landholders, enabled a broader reach and a greater outcome; it’s something we hope to replicate in other key areas.’

“Marlee is one of the most important conservation reserves in Mandurah and prized by our community,” Ms Knight said.

The PHBG can support landholders of all property sizes with their control of foxes through options such as trap hire and restricted chemical permit application subsidies. It can also help landholders connect with local shooting organisations.

Collected data can be used before and after control programs to show the positive impact coordinated community efforts have on decreasing the number of feral animals in an area.

If you, or your neighbours are noticing foxes contact the Group by emailing Fox activity, damage and control activities can also be recorded using the FeralScan resource. This resource helps stakeholders come together to plan coordinated control across fence lines and tenure.

Heads up results in cotton bush control

“It was very frustrating trying to control cotton bush that was re-infesting my property from an established problem over a fence. I was so relieved when my friendly heads up led to a massive effort by the new landowner to control and remove the cotton bush on his property”
