Creature Feature – Litoria moorei (Motorbike Frog)

As one of WA’s most sighted (or more likely, heard) frog species, the Motorbike Frog is well known for both its striking appearance and its unmistakable call that mimics the revving and gear-shifting of a motorbike.

Litoria moorei is a powerfully built species with long hind legs and noticeable finger and toe discs that help it climb up to two metres high. Despite being a ground-dwelling frog, it often turns up on shrubs, rocks, and even garden walls, earning it the nickname ‘tree frog’.

Their colouration is just as impressive. Depending on conditions, their backs may shift from bright green with gold after basking in the sun, to a deep, uniform brown in cooler weather. Their bellies vary from pale green to light brown, and adults can grow up to 7.5 cm in length.

This species is almost identical to the Spotted-thighed Frog (Litoria cyclorhyncha) in appearance, call, and genetics. The key distinguishing feature? Motorbike Frogs lack the characteristic spots on the thighs.

Motorbike Frogs thrive around swamps, lakes, vegetated watercourses, farm dams, and garden ponds across Western Australia. These wet, sheltered environments offer ideal conditions for feeding, breeding, and shelter.

Sitting squarely in the middle of the food chain, Motorbike Frogs play a crucial role in balancing local ecosystems. They help control insect populations and other small prey, while also serving as an important food source for larger predators such as birds, snakes, and native carnivorous marsupials.

Breeding kicks off in early spring and continues into summer. During this time, males call from floating vegetation, reed beds, open dam edges, or even tree branches, broadcasting their iconic motorbike-like call to attract mates.

After mating, females lay large clumps of eggs attached to floating or submerged vegetation, encased in a clear jelly. Tadpoles emerge as dark brown swimmers with a metallic sheen on their underside and may reach up to 8 cm in length. Early-stage tadpoles often swim in schools and typically remain hidden among vegetation in permanent water bodies.

Metamorphosis usually occurs from March to April, when juvenile frogs begin taking their first hops onto land!

CEO’s Report

In 2020-21 I talked about ‘raising the bar’. In 2021-22 we worked on setting the bar on fire. Over the last 12 months, the team at NACC NRM has not stopped.

The Sustainable Agriculture team has extended the program’s reach through collaborations with grower groups in the regions. Specifically, the Beyond Reasonable Drought project and Grower Group Alliance – South West WA Drought Innovation Hub – Geraldton Node project. The Beyond Reasonable Drought partnership with grower groups supported farmers across the region to improve the environmental sustainability of their agricultural production and drought resilience. The outcomes of this project have been consolidated through our successful Expression of Interest to the South West WA Drought Innovation Hub, with support from grower groups across the region, to host the Geraldton Node of the Hub. The program continues to focus on working with agricultural networks to share technical expertise and provide opportunities that will improve land management practices in agriculture across the region.

The conservation outcomes of ranger teams have expanded through work on several land tenures. Maintaining Heritage sites such as Willi Gulli, Racecourse Paddock and Buller River has long been a priority. During 2021-22, the teams have increasingly focused on threatened species and ecosystems.

To this end, Western Mulga rangers have improved management across 19,000 ha for the conservation of Malleefowl through firebreak and access management. They completed the maintenance of water holes and supported the monitoring of over 90 Malleefowl mounds.

Similarly, the Kwelena Mambakort Aboriginal Corporate ranger team have contributed positively to Carnaby’s Black Cockatoo populations by installing artificial hollows and habitat restoration.

All ranger teams have collected native seed, propagated native plants for restoration, and planted native vegetation in key locations across the NAR. Seed collection provides valuable industry experience and has facilitated the planting of over 100,000 seedlings during the year.   

In September 2021, the NACC NRM team delivered the WA Threatened Species Forum, held in tandem with the National Malleefowl Forum. Given the impact of COVID and the timing of this event, having more than 100 delegates from all over Australia was a significant achievement. The two Forums brought together 12 events over five days and featured 14 local artists, 25 businesses and 36 youth participants.

Following the successful relaunch of our updated NARvis, NACC NRM was invited to help lead a significant piece of strategic planning work for the region with Mid West Development Commission and the Department of Primary Industries and Regional Development. With funding from the Australian Government’s Future Drought Fund, the consortia delivered a Regional Drought Resilience Plan covering the shires of Northampton and Chapman Valley and the City of Greater Geraldton, along with significant technical analysis of drought vulnerability for the South West land division. The development of this plan also included extensive community consultation to ensure that local knowledge and technical advice guided the development of priorities for action.

This planning work links to existing NACC NRM on-ground projects, including Beyond Reasonable Drought and the Chapman Catchment Collaborative regeneration project.

It was a busy year for events with face-to-face events becoming commonplace again. During 2021-22 we hosted events in Gingin, Moora, Dalwallinu, Cervantes, Jurien Bay, Walkaway, Nabawa, Perenjori, Kalannie and Morawa. We supported events in Karakin, Thundellara, Perenjori, Paynes Find, Wubin, Cataby, Warradarge, Northampton, Yuna, Dalwallinu and Dandaragan.

We also supported on-ground works throughout the region, including at the following locations Yuna, Dalwallinu, Dandaragan, Merkanooka, Goodlands, Kalannie, Bunjil, Yardarino, Canna, Kondut, Latham, Kadathinni, Nabawa, Red Gully, Sandy Gully, Waddy Forrest, Devils Creek, Perenjori, Bowgada, Ellendale, Wandana, Namban, Hill River, Warradarge, Gillingarra, Regans Ford and Moonyanooka.

Our region is vast – slightly larger than Tasmania, which for comparison, is serviced by three separate NRM organisations. Covering the NAR region and its many environmental threats is challenging. We continue to focus on partnerships and collaboration to address this challenge. We know that by working with our community through passionate delivery of collaborative on-ground projects and education, the community will value and actively protect our region’s natural capital.

This year we have launched a new Reconciliation Action Plan (RAP). The RAP Working Group consulted widely and developed an Innovate RAP which Reconciliation Australia approved in March 2022. The activities to fulfil these commitments are now in full swing.

Sadly, at the end of 2021, we farewelled former NACC NRM CEO Shelley Spriggs, who lost a long battle with cancer. Shelley was an inaugural inductee to the NRM Leadership Honour Roll. I will always be grateful for her guidance and no-nonsense approach, not to mention her passion for life.

While we have said farewell to some, we have welcomed many new faces across all programs, including our Administration team. We have also hosted a school-based trainee from Nagle Catholic College who has been working towards a Certificate II in Conservation and Ecosystem Management. This trial position has been very successful, and we look forward to making this opportunity available again in 2023.

During 2022 we have taken on new projects that align with our organisational and program objectives, and we have successfully completed some great initiatives that support continued conservation and sustainability outcomes. I want to thank the whole team who continue to go above and beyond for the organisation and each other proving their ongoing commitment to our purpose and our values.
