Pioneering drone technology to protect Australia’s wildlife
Conservation scientist Dr Ryan Witt and his team are tracking and mapping cryptic species—from using thermal drones to locate koalas and greater gliders to tagging squirrel gliders. Their work is advancing wildlife protection and helping guide more informed environmental decisions.
Making wildlife count: drones, data and a clearer path for conservation
Ryan is a conservation scientist driven by one key goal—ensuring Australia’s threatened wildlife is seen, counted and considered in the decisions that shape their future.
As a researcher at the University of Newcastle, Ryan leads a small team of early career researchers developing cutting-edge drone-based monitoring tools that make it harder for species to be overlooked—and easier for governments, industry and communities to make informed, accountable choices.
“If wildlife isn’t showing up in the data, it’s not showing up in the decisions,” Ryan says.
“That’s why our work is about improving visibility, strengthening the evidence—and, hopefully, helping keep the process surrounding wildlife impacts honest.”
A childhood curiosity that never left
Really, Ryan says, you can blame his parents.
Growing up in the suburbs of Newcastle, his mum nurtured his curiosity by taking him to wildlife parks and encouraging hands-on experiences with native animals like wallabies. His dad took him bushwalking through urban reserves like Glenrock, helping him notice the quiet, everyday wonders of the bush. He also spent countless evenings feeding possums on the back deck.
“They’re the reason I do what I do,” he says.
“They gave me the chance to connect with nature, and that’s what set this whole journey in motion.”
That early passion led Ryan into a PhD in marsupial reproductive biology, working on assisted breeding techniques for native species. But over time, his focus shifted toward the field—where habitat loss and landscape change demanded faster, scalable tools to detect and protect species before they disappear.
Drones that bring wildlife into focus
Since 2019, Ryan has led the development of a thermal drone survey method to detect and monitor hard-to-find species like koalas, greater gliders and squirrel gliders.
These animals are especially vulnerable to land clearing due to their site fidelity—their tendency to return to the same trees year after year.
“If those trees go, often so do they,” Ryan says.
The method Ryan’s team developed enables real-time detection using spotlight-equipped drones, and supports population estimates across entire landscapes—a level of accuracy and scale rarely possible with traditional methods.
An early proof-of-concept for detecting koalas with drones was co-developed with the . But the operational method used today—including real-time detection and population estimation—was developed and field-tested by Ryan’s team, with core support from , and further support from , , , , and .
From better data to better decisions
Now in use across NSW, the method is referenced in key frameworks like the and the . What sets it apart is its ability to directly detect animals at scale—providing reliable data to inform planning, development and conservation efforts.
“It’s not about stopping any particular project—it’s about making sure decisions are made with a more complete picture,” Ryan says.
“If the data is strong and consistent, the decisions that follow are hopefully better for wildlife.”
Ryan’s team also tracks species like squirrel gliders and koalas to better understand how they use fragmented habitats. By combining GPS collars, ecological modelling, nest box monitoring and genetic tools, they’re gathering vital data on movement, health, and population structure—insights that help guide conservation actions from the urban forests of Newcastle to the national parks of NSW.
Collaboration with purpose
While Ryan leads the research team, he emphasises the role of his team and their shared commitment.
“This is definitely not a solo effort, I’m incredibly proud of the early career scientists I work with,” he says.
“Their expertise, creativity, and care for the work has taken this from an idea to something that’s making real change.”
Working across disciplines, the team brings together expertise in ecology, spatial modelling, drone operations and data science—combining practical fieldwork with technical innovation.
The small team collaborates widely—with government departments, environmental NGOs, industry and community conservation groups—ensuring the science is accessible, scalable and useful across sectors.
Keeping wildlife in the frame
At its heart, Ryan’s work is about giving wildlife a stronger voice in the decisions that affect them. It’s about making threatened species impossible to overlook.
“We’re working to make sure species don’t disappear because no one knew they were there,” he says.
“Good data keeps the conversation honest—and helps everyone do better.”
From backyard possums to conservation policy, Dr Ryan Witt and his team are using drone technology and ecological data to build a future where Australia’s iconic wildlife are seen, valued, and protected—before it’s too late.

Career Summary
Biography
Dr Ryan Witt is a wildlife ecologist specialising in the use of drone technology and ecological data to improve how Australia’s threatened species are detected, monitored, and protected. His work focuses on developing tools that make native wildlife more visible in the systems that shape conservation, development, and land management decisions.
Ryan leads a growing research program at the University of Newcastle, where he and his team develop and refine thermal drone-based monitoring methods for koalas, gliders, and other cryptic marsupials. His work spans from urban reserves in Newcastle to landscape-scale surveys across national parks in New South Wales—delivering scalable tools that are fast, accurate, and transparent.
A Newcastle local, Ryan is committed to building research partnerships that not only protect local wildlife but also contribute to broader national strategies for biodiversity conservation.
Research Interests and Expertise
Ryan’s research sits at the intersection of technology, ecology, and applied conservation. He is best known for developing a thermal drone survey method that allows for real-time detection and population estimation of species like koalas, greater gliders and squirrel gliders—many of which are vulnerable to habitat loss due to their strong site fidelity. His method is now referenced in state frameworks including the NSW Koala Strategy and the Biodiversity Assessment Method.
Ryan frequently collaborates across sectors—working with government agencies, industry, NGOs, and community organisations. His partnerships have included WWF-Australia, Taronga Conservation Society Australia, the FAUNA Research Alliance, Hunter Water, Koala Conservation Australia, the NSW Department of Climate Change, Energy, the Environment and Water, NSW Local Land Services, CSIRO, NSW National Parks and Wildlife Service, and local governments such as Newcastle City Council, Port Stephens Council, and MidCoast Council.
He has also worked closely with Indigenous organisations including Taree Indigenous Development and Employment (TIDE), the Miromaa Aboriginal Language and Technology Centre, and the Karuah Local Aboriginal Land Council.
Ryan also leads GPS-collar tracking studies focused on low-density koala populations. These projects aim to evaluate movement ecology, health, longevity, and population dynamics in koala populations under threat—providing much-needed insights for planning interventions and assessing population viability.
In addition to koalas, his team monitors squirrel gliders using a combination of nest boxes, pipe traps, GPS tracking, and genetic sampling, helping to map their urban range, assess population size, and support wildlife corridor planning.
Although trained in marsupial reproductive biology, Ryan now spends the majority of his time focused on field-based ecological solutions. His PhD research addressed ovulation timing challenges in marsupial breeding programs and continues to inform the reproductive science underpinning assisted breeding and genome storage initiatives.

Location: South-eastern Australia; New South Wales. Time Period: 2019¿2022. Major Taxa Studied: A total of 982 species of plants and animals, in eight taxonomic groups: amphibians, birds, fish, insects, mammals, molluscs, plants and reptiles. Methods: We collated 545,223 plant and animal response records from 47 field surveys of 4613 sites that focussed on areas burnt in 2019¿2020. For each site, we calculated remotely sensed signals of fire heterogeneity and post-fire biomass recovery, including the delayed recovery index. Meta-regression analyses were conducted separately for species that declined after fire (negative effect sizes) and species that increased after fire (positive effect sizes) for each buffer size (250 m, 500 m, 1 km, 1.5 km, 2 km and 2.5 km radius). Results: We found that species exposed to homogenous high-severity fire (i.e., low fire heterogeneity) were more likely to exhibit decreased abundance/occurrence or inhibited recovery. Areas with delayed recovery of biomass also had significant negative on-ground responses, with lower abundance or occurrence in areas where biomass recovery was slower. Main Conclusions: The fire heterogeneity index and the delayed recovery index are suitable for inclusion in monitoring and reporting systems for tracking relative measures over time, particularly when field survey data is not available at the landscape scales required to support reporting and management decisions. Locations with remotely sensed signals of delayed recovery should be prioritised for protection against further disturbances that may interfere with the recovery process. Research attention must next focus on how cumulative fire heterogeneity patterns of successive fires affect the post-fire recovery dynamics to further inform the application of remote sensing indicators as management tools for biodiversity conservation.

A key challenge is to discover how interactions among fire-regime components, drought and land tenure shape wildfire impacts. The globally unprecedented3,4 2019¿2020 Australian megafires burnt more than 10 million hectares5, prompting major investment in biodiversity monitoring. Collated data include responses of more than 2,000 taxa, providing an unparalleled opportunity to quantify how megafires affect biodiversity. We reveal that the largest effects on plants and animals were in areas with frequent or recent past fires and within extensively burnt areas. Areas burnt at high severity, outside protected areas or under extreme drought also had larger effects. The effects included declines and increases after fire, with the largest responses in rainforests and by mammals. Our results implicate species interactions, dispersal and extent of in situ survival as mechanisms underlying fire responses. Building wildfire resilience into these ecosystems depends on reducing fire recurrence, including with rapid wildfire suppression in areas frequently burnt. Defending wet ecosystems, expanding protected areas and considering localized drought could also contribute. While these countermeasures can help mitigate the impacts of more frequent megafires, reversing anthropogenic climate change remains the urgent broad-scale solution.

The peer mentors in this study are high-achieving students who previously completed the same course and who were hired and trained to facilitate Peer Assisted ÁñÁ«³ÉÈËappÏÂÔØ Sessions (PASS). PASS gives students the opportunity to deepen their understanding through revision and active learning and are typically held outside of class time. In contrast, our trial embedded peer mentors into classes for a large (-250 students) first-year workshop-based course. We employed a participatory action research methodology to facilitate the peer mentors' cocreation of the research process. Data sources include peer mentors' journal entries, student cohort data, and a focus group with teaching staff. We found that during face-to-face workshops, peer mentors role-modelled ideal student behaviour (e.g., asking questions) rather than acting as additional teachers, and this helped students to better understand how to interact effectively in class. The identity of embedded peer mentors is neither that of teachers nor of students, and it instead spans aspects of both as described using a three-part schema comprising (i) identity, (ii) associated roles, and (iii) associated practices. As we moved classes online mid-semester in response to the COVID- 19 pandemic, mentors' identities remained stable, but mentors adjusted their associated roles and practices, including through the technical aspects of their engagement with students. This study highlights the benefits of embedding mentors in classrooms on campus and online.

[more] The 'Compassionate Conservation' movement is gaining momentum through its promotion of 'ethical' conservation practices based on self-proclaimed principles of 'first-do-no-harm' and 'individuals matter'. We argue that the tenets of 'Compassionate Conservation' are ideological - that is, they are not scientifically proven to improve conservation outcomes, yet are critical of the current methods that do. In this paper we envision a future with 'Compassionate Conservation' and predict how this might affect global biodiversity conservation. Taken literally, 'Compassionate Conservation' will deny current conservation practices such as captive breeding, introduced species control, biocontrol, conservation fencing, translocation, contraception, disease control and genetic introgression. Five mainstream conservation practices are used to illustrate the far-reaching and dire consequences for global biodiversity if governed by 'Compassionate Conservation'. We acknowledge the important role of animal welfare science in conservation practices but argue that 'Compassionate Conservation' aligns more closely with animal liberation principles protecting individuals over populations. Ultimately we fear that a world of 'Compassionate Conservation' could stymie the global conservation efforts required to meet international biodiversity targets derived from evidenced based practice, such as the Aichi targets developed by the Convention on Biological Diversity and adopted by the International Union for the Conservation of Nature and the United Nations.

Rece... [more] Compassionate conservation focuses on 4 tenets: first, do no harm; individuals matter; inclusivity of individual animals; and peaceful coexistence between humans and animals. Recently, compassionate conservation has been promoted as an alternative to conventional conservation philosophy. We believe examples presented by compassionate conservationists are deliberately or arbitrarily chosen to focus on mammals; inherently not compassionate; and offer ineffective conservation solutions. Compassionate conservation arbitrarily focuses on charismatic species, notably large predators and megaherbivores. The philosophy is not compassionate when it leaves invasive predators in the environment to cause harm to vastly more individuals of native species or uses the fear of harm by apex predators to terrorize mesopredators. Hindering the control of exotic species (megafauna, predators) in situ will not improve the conservation condition of the majority of biodiversity. The positions taken by so-called compassionate conservationists on particular species and on conservation actions could be extended to hinder other forms of conservation, including translocations, conservation fencing, and fertility control. Animal welfare is incredibly important to conservation, but ironically compassionate conservation does not offer the best welfare outcomes to animals and is often ineffective in achieving conservation goals. Consequently, compassionate conservation may threaten public and governmental support for conservation because of the limited understanding of conservation problems by the general public.

[more] The effect of treatment with Lucrin Depot (1 month), a microsphere gonadotrophin-releasing hormone agonist preparation, was investigated in the fat-tailed dunnart (Sminthopsis crassicaudata) as a potential strategy to synchronise cycling. The status of the ovaries (ovarian size, number and size of Graafian follicles and corpora lutea) and reproductive tract (weight, vascularity and muscularity) in twelve untreated females were assessed to establish the activity parameters for randomly selected cycling animals. Thirty-six females were treated with 1mgkg-1 (n=12), 10mgkg-1 (n=12) or 20mgkg-1 (n=12) Lucrin Depot. At 4, 6 and 8 weeks the reproductive tracts were assessed using the criteria developed in the untreated females. All of the females treated with 10mgkg-1 showed suppression at 4 weeks and 25% showed return of reproductive activity at 8 weeks. A dose of 1mgkg-1 did not appear to suppress reproductive activity and 20mgkg-1 gave equivocal results, with evidence of both suppression and activity. The results indicate that Lucrin Depot appears to be a promising agent to regulate and potentially synchronise breeding activity in the fat-tailed dunnart.
