Peel Harvey Biosecurity Group (PHBG) launched the Weed Wiper Loan Program in 2021 to combat the invasive and toxic Cape tulip ( Moraea flaccida and miniata ). This initiative offers a cost-effective, environmentally responsible and selective control method by making weed wipers available for landowners to borrow at no cost. A weed wiper directly applies herbicide to the comparatively tall Cape tulip, killing the weed while preserving the valuable underlying pasture. This approach significantly reduces overall herbicide use and spray drift compared to conventional boom spraying. The program has grown consistently since its introduction. Beginning with under 20 landholders who borrowed PHBG's weed wipers, participation has more than tripled. In 2025, the program had over 60 participating landholders. The program’s impact is particularly strong in the Shire of Serpentine Jarrahdale, which accounted for over 80% of equipment loans in 2025.  The future In response to increasing demand ...

Peel Harvey Biosecurity Group (PHBG) recently carried out a targeted release of calicivirus, or rabbit hemorrhagic disease (RDHV), to help manage feral rabbit populations across the Peel-Harvey region. This initiative is an annual effort and forms part of PHBG’s ongoing pest control efforts in cooperation with the community and local government. Blood testing results Before the release, PHBG collected 38 blood samples from rabbits across its operational area to test for calicivirus antibodies, which indicate immunity to the virus. Blood samples from 38 rabbits were analysed. The results showed that 21% tested positive for RHDV1 antibodies, while 66% carried antibodies for RHDV2 — the dominant wild strain. Rabbits can test positive for antibodies of both strains. The high presence of antibodies indicated that a region-wide calicivirus release would be ineffective at reducing rabbit numbers.  Community participation A total of 54 landholders registered to take part in the blood drive...

Pesky Pests is a free, science-based education program for Foundation to Year 6 students, focused on environmental sustainability and linked to the Australian Curriculum. Read on to find out what's been happening during Term 1 of 2025. Update on the 2025 program Our Pesky Pests science education program for primary schools is off to a strong start in its second year. 2025 began with engaging school holiday sessions at local libraries, followed by our popular incursions making their way into classrooms as the school year got underway. What's in a Pesky Pests incursion? In a 90-minute lesson on feral animals, students explore the impact of invasive species and how to investigate the signs to identify local pests. Or in the seeds lesson, they learn what makes a plant invasive, examine the fascinating variety of seed shapes, and take part in hands-on experiments to understand how seeds spread through the environment. State NRM Stewardship grant application Building on the success ...
