The sound of summer has reached my backyard in the last few weeks with the increase in cicadas. It started with the small species and then followed the Red Eye Cicada Psaltoda moerens. Since then I have been looking every morning to find newly emerged cicadas.
Red Eye Cicada: Psaltoda moerensEastern Double Drummer; Thopha saccata
Cicadas are the loudest insects in the world and emerge from their underground world in late spring and summer. The peak Cicada season is November and December.
Cicadas spend most of their life underground with many large Australian species living underground as nymphs for around 6-7 years. This is why in certain years some species are more abundant than others, there is often peaks every few years.
The life of an adult cicada is very short, lasting only a few weeks. The female cicada lays its eggs by piercing plant stems and inserting the eggs into the slits it has made. The eggs hatch and are small, wingless nymphs. They fall to the ground and burrow below the surface. They live on the sap from plant roots and when the nymph reaches full size it digs its way to the surface. The nymphs then climbs on to a tree trunk or other object and sheds its skin for the last time. The fully-winged adult cicada which emerges leaves its old empty skin behind.
Cicadas Mating
Did you know?
Australia has an estimated 750 to 1000 species of cicada
Only male cicadas sing. They do this in an attempt to find a mate.
Different species have different songs to attract only their own kind.
Adult cicadas have short lives, usually only a few weeks.
Most of their lives are spent as nymphs underground. For some species this can be up to several years.
Cicadas feed only on plant sap using their piercing, sucking mouthparts.
Cicadas feed on a huge range of plants, including eucalypts and grasses.
Birds, bats, spiders, wasps, ants, mantids and tree crickets all prey on cicadas.
This is a video I recorded in my backyard in early November 2024
Listen out for the sounds of cicadas and keep an eye out for their exoskeletons on trees, walls, fences and shrubs.

Transforming a garden into a thriving wildlife sanctuary is a rewarding and impactful way to support local biodiversity and connect with nature. I have had a great time working on the garden and creating a space that is relaxing for me and haven for local wildlife.
My goal was clear: design a garden that would support native flora and fauna while creating an inviting natural oasis. Native plants were chosen for their resilience and compatibility with local species, while a dragonfly garden with a water feature was included to attract dragonflies, damselflies, and frogs. By providing a habitat with food, shelter, and water, the garden aimed to draw in various species and give them a safe place to thrive. I now have a Water Dragon that lives nearby, tadpoles, damselfly and dragonfly nymphs living in the pond.
I started the process of The transformation was almost immediate. With the native plants taking root, insects and small animals quickly followed. The pond became a lively centre of activity, home to dragonflies, damselflies, and tadpoles. Stripe marsh frogs and common eastern froglets were soon heard calling, marking the garden as a hotspot for native frogs.
Key Elements of the Wildlife Garden
Native Plants and Vegetation: Carefully selected native plants formed the backbone of the garden. Hardy shrubs, grasses, and flowering plants created a layered structure that mimicked local bushland. These plants provide food and shelter for insects, birds, and small mammals while requiring minimal maintenance.
Dragonfly Garden and Pond: The heart of the project was a small pond, ideal for attracting dragonflies, damselflies, and native frogs. Shallow and shaded at the edges but deeper in the centre, the pond was lined with rocks and aquatic plants that offered ideal spawning grounds for tadpoles and larvae, adding biodiversity to the garden ecosystem.
Log and Rock Piles: Strategic log and rock piles added structure to the garden, offering hiding spots for reptiles, insects, and small mammals. These features also help to retain moisture, creating a microhabitat that attracts invertebrates, which in turn attract other wildlife up the food chain.
During the night I hear the unmistakable calls of the Powerful Owl and Southern Boobook Owl echoed through the garden, suggesting that even these top predators were taking note of the new ecosystem. The presence of these owls, which rely on small mammals and other prey, indicated that the garden was supporting a complex food web.
The increase in insect life attracted various bird species, enriching the biodiversity and adding another layer to the garden’s ecosystem.
Creating a successful wildlife garden is not only about design but also about patience and careful observation.
This wildlife garden is a testament to the impact of intentional, eco-friendly gardening, proving that even small spaces can support diverse and thriving ecosystems. For anyone inspired to start their own wildlife garden, this success story offers a roadmap and motivation to begin. By embracing native plants and creating a few key habitats, any garden can become a sanctuary for local wildlife, benefiting both the environment and the community.
Todays dive was great and long overdue. I hadn’t been in the water since I moved at the end of last year. My sister and I went to the Haven on the Central Coast. It was a beautiful spring day, a liitle surgy in the water and not great visability, but wow it was amazing.
Despite their fearsome appearance, morays are not considered dangerous to people. In Australia the Green Moray occurs in temperate coastal waters.
Port Jackson Shark
Port Jackson Shark, Heterodontus portusjacksoni are very common tis time of year, between May – October. The teeth of the Port Jackson Shark are not serrated and are used to hold and break, then crush and grind the shells of molluscs and sea urchins.
Smooth Stingray
We saw a huge Smooth Stingrays Bathytoshia brevicaudatais hiding in the sand when we were on the way back to shore. We could see the tail sticking out and the rest of the body was covered itself in sand. You could just see the outline of the stingray and the eyes sticking out above the sand. The Smooth stingray are the largest stingray in the world, but sometimes still hard to spot.
World Rivers Day is a celebration of the World’s Waterways! It highlights the many values of our rivers, strives to increase public awareness, and encourages the improved stewardship of all rivers around the world. Rivers in virtually every country face an array of threats, and only through our active involvement can we ensure their health in the years ahead.
Celebrate World Rivers Day with me for Riverfest. Riverfest is the Parramatta River Catchment Group’s annual event – celebrating the Parramatta River and surrounding creeks and environment!
I will be delivering FREE live virtual excursions on Thursday 26 and Friday 27 September. If you are in Sydney you can join me at the Paint the River on World Rivers Day event at Paramatta Park on Sunday 29 September.
FREE live Virtual Excursion at 2pm on Thursday 26 September
A river is a natural watercourse flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water.
A catchment is an area where water is collected by the natural landscape. A catchment is usually surrounded by hills or mountains. Gravity causes rain, melting snow and other water in the catchment to run downhill where it flows into creeks, rivers, lakes and eventually the ocean. The water that seeps below ground and settles in the soil and the space between rocks is called groundwater.
Threatened Species Day is recognised across the Australia on 7 September every year to raise awareness of plants and animals at risk of extinction. Threatened Species Day acknowledges the death of the last remaining Thylacine, Tasmanian tiger at Hobart Zoo in 1936.
Australia is renowned for its extraordinary wildlife, with unique species that can’t be found anywhere else in the world. But with this rich biodiversity comes an unfortunate reality: many of our native animals are on the brink of extinction. Since European settlement, more than 100 species have been lost.
Unfortunately Australia is home to more than 1,800 species currently listed as threatened, including mammals, birds, reptiles, amphibians, and plants. Threatened Species Day is a call to action. It’s a moment to reflect on the species we’ve lost and a powerful reminder to protect those we still have.
The key drivers of species decline in Australia include:
Habitat destruction: Urbanization, land clearing for agriculture, and mining have destroyed vast areas of natural habitat.
Invasive species: Introduced animals such as foxes, cats, and rabbits have devastated native wildlife populations.
Climate change: Rising temperatures, bushfires, and prolonged droughts are pushing species beyond their limits.
Pollution: Waterways and ecosystems are increasingly under threat from pollution, including plastic waste.
How You Can Help
Saving Australia’s threatened species might seem daunting, but there are actions each of us can take to make a difference. Here are some meaningful ways to get involved:
Support Conservation Organizations
Many non-profit organizations across Australia work tirelessly to protect threatened species and their habitats. Supporting groups like the World Wildlife Fund (WWF), the Australian Wildlife Conservancy, or local wildlife rescue centers through donations or volunteering can make a huge difference. Your contribution helps fund research, habitat restoration, and species recovery programs.
Create Wildlife-Friendly Spaces
Whether you have a sprawling backyard or a small balcony, creating wildlife-friendly spaces is a practical way to help. Planting native trees and shrubs provides food and shelter for local birds, insects, and small mammals. Installing nesting boxes for birds, possums, or microbats can also offer safe havens for these creatures. Even small actions like placing water bowls out during the hot summer months can support local wildlife.
Say No to Single-Use Plastics
Plastic pollution is a major threat to marine life, with countless animals affected by ingesting or becoming entangled in plastic waste. Reducing your reliance on single-use plastics—like bags, straws, and packaging—can prevent these items from ending up in our oceans and rivers. Opt for reusable alternatives and dispose of waste responsibly.
Be a Responsible Pet Owner
Pets, especially cats and dogs, can pose significant threats to native wildlife. Keeping your pets indoors or supervising them outside, especially in areas where threatened species may live, can prevent them from hunting or disturbing local animals. Desexing pets and ensuring they are microchipped helps reduce stray populations, which often prey on wildlife.
Get Involved in Citizen Science
Many conservation programs rely on the public to help monitor species populations. Citizen science initiatives like BirdLife Australia’s backyard bird count, the Australian Koala Foundation’s koala surveys, or FrogID allow everyday Australians to contribute to important scientific data. These efforts help researchers track changes in populations and better understand the needs of threatened species.
Advocate for Stronger Environmental Laws
While individual actions are important, systemic change is essential for long-term conservation success. Stay informed about environmental issues and advocate for stronger environmental protections, particularly when it comes to land clearing, mining, and deforestation. Contact your local representatives, sign petitions, and participate in community meetings where decisions about land use are being made.
A Shared Responsibility
Saving Australia’s threatened species is a shared responsibility. Each one of us has a role to play, whether it’s through everyday actions like reducing waste, getting involved in local conservation projects, or speaking up for stronger environmental protections.
Threatened Species Day is a moment for reflection, but it’s also a call to action. Together, we can ensure that future generations have the chance to witness the beauty and diversity of Australia’s wildlife—not just in pictures or history books, but in the wild, where these creatures belong.
September marks Biodiversity Month, a time dedicated to appreciating and understanding the incredible variety of life on Earth. From the tiniest microorganisms to the largest mammals, biodiversity encompasses the entire range of species that inhabit our planet. This month offers a unique opportunity to reflect on the importance of preserving biodiversity and to recognise the intricate relationships that sustain our ecosystems.
Biodiversity refers to the variety of living organisms in a particular habitat or ecosystem. It includes the diversity within species (genetic diversity), between species (species diversity), and the diversity of ecosystems themselves. These elements work together to create the complex web of life that supports all living beings, including humans.
Biodiversity is crucial for maintaining ecological balance. Each species plays a specific role in its ecosystem, contributing to functions like pollination, nutrient cycling, and pest control. The loss of even a single species can disrupt these processes, leading to unforeseen consequences.
Biodiversity also directly impacts human health and well-being. Many of our medicines, foods, and materials are derived from natural sources. A diverse ecosystem also provides clean air, water, and fertile soil, all of which are essential for our survival.
Many cultures around the world have deep connections with nature. Biodiversity is woven into traditions, spiritual beliefs, and practices that define cultural identities. Protecting biodiversity is also about preserving this cultural heritage.
Ecosystems with high biodiversity are more resilient to environmental changes, such as climate change. A diverse gene pool allows species to adapt to new conditions, ensuring the survival of ecosystems even in the face of challenges.
Threats to Biodiversity
Despite its importance, biodiversity is under threat from various human activities. Deforestation, pollution, climate change, and overexploitation of natural resources are leading to habitat loss and species extinction at an alarming rate. According to the United Nations, around one million animal and plant species are now threatened with extinction.
How Can We Protect Biodiversity?
Supporting conservation projects, whether through donations, volunteering, or spreading awareness, is a powerful way to protect biodiversity. This includes preserving natural habitats, supporting wildlife protection laws, and creating more protected areas.
Adopting sustainable practices in our daily lives can significantly reduce our impact on the environment. This includes reducing waste, conserving water, choosing sustainably sourced products, and supporting eco-friendly companies.
Educating ourselves and others about the importance of biodiversity is crucial. The more people understand the value of biodiversity, the more likely they are to support conservation efforts and make environmentally conscious decisions.
Advocating for policies that protect biodiversity, such as stronger environmental regulations and support for renewable energy, can lead to significant positive changes on a global scale.
Whether you’re planting native species in your garden, participating in a local clean-up, or simply taking a moment to appreciate the natural world, every action counts.
Let’s commit to making small changes that contribute to a more sustainable future. By working together, we can ensure that the incredible variety of life on Earth continues to thrive for generations to come.
What a week, but really I should say what a month! August has been awesome, with so many events and programs linked to National Tree Planting Day, National Science Week and Book Week.
It was wonderful to be back at the Rhodes Science Festival with Mary Bell from Nature Knows for National Science Week. We always have so much fun talking to visitors and there is always a great vibe at the event.
I presented the What’s in your Backyard virtual excursion for SciFest 2024, celebrating National Science Week. Almost 4000 students were registered for the event and many classes have followed up and watch the recording below.
I also created and delivered amazing series of online trivia events for SciFest 2024. I did 4 session linking to the National Science Week Theme Species Survival – More Than Just Sustainability. There were over 6500 students register across, Biology trivia, Australian Animal trivia, Plant life trivia and Environmental trivia.
It was great to be able to follow up from National Tree Planting Day and do some school tree planting with Greening Australia. Tree Planting enables people to make new habitat zones, improve green spaces, increases shade and creates connection to nature. There are so many ecological and social benefits from tree planting and it is great to be involved in Greening Australia’s Cooling the School program.
Cooling the Schools is an initiative delivered by Greening Australia and funded by the NSW Department of Planning, Housing and Infrastructure. Watch a short video from Ferncourt Public School about there Colling the Schools experience.
I delivered a STEM family activities with Little Scientist at an early childhood centre on the Central Coast NSW. There were 80 children participating in 4 inquiry based learning activities across the afternoon. Children were constructing towers or creating a tool to carry a ping pong ball around an obstacle course. Everyone had a lot of fun.
I wrapped up August with the Willoughby Fauna Fair. This year was the 20th anniversary of the event. The What’s in your Backyard display and Nature Craft activity fit perfectly into this year’s theme Our Awesome Urban Survivors and celebrated the resilience and adaptability of wildlife in urban environments.
I definitely deserve a break after all these events, but September is Biodiversity Month and the 5th anniversary of launching Australian Environmental Education. Maybe October will be quieter!
Trees play a vital role in supporting life on Earth and their significance encompasses ecological, environmental, social, and economic aspects. You can make a difference by planting tree on any day especially Schools Tree Day on Friday 26th July, National Tree Day is Sunday 28th July.
Planet Ark’s National Tree Day started in 1996 and has grown into Australia’s largest community tree planting and nature care event. It’s a call to action for all Australians to get their hands dirty and give back to the community.
Here are some key reasons why trees are essential:
Oxygen production: Trees are primary producers of oxygen through the process of photosynthesis. They absorb carbon dioxide from the atmosphere and release oxygen, making the air we breathe cleaner and more breathable.
Carbon sequestration: Trees act as natural carbon sinks, absorbing and storing carbon dioxide, a major greenhouse gas responsible for climate change. They play a critical role in mitigating the effects of global warming by reducing the concentration of CO2 in the atmosphere.
Biodiversity support: Forests, which are primarily composed of trees, are incredibly diverse ecosystems that provide habitat and sustenance for a vast array of plants, animals, insects, and microorganisms. Trees contribute to the preservation of biodiversity and help maintain a balanced ecosystem.
Soil conservation: Tree roots help prevent soil erosion, which is crucial for maintaining fertile soil and preventing landslides and desertification.
Water cycle regulation: Trees influence the water cycle by absorbing and releasing water through their roots and leaves. They help regulate rainfall patterns, prevent floods, and maintain groundwater levels.
Climate regulation: Large forests and mature trees have a moderating effect on local and global climates. They regulate temperature, humidity, and precipitation patterns, creating a more stable environment.
Wildlife habitat: Trees provide shelter, food, and nesting sites for a wide range of animal species, including birds, mammals, and insects. Many creatures rely on trees for their survival.
Economic value: Trees are essential for various industries, including timber, paper, and pharmaceuticals. They provide raw materials for construction, furniture, and other products, supporting economies and livelihoods.
Aesthetic and recreational benefits: Trees enhance the beauty of landscapes, parks, and urban areas, contributing to the overall well-being and mental health of people. Green spaces with trees offer opportunities for relaxation and recreation.
Air quality improvement: Trees act as natural air purifiers, filtering harmful pollutants and particulate matter from the air, which is especially crucial in urban environments with high levels of pollution.
Noise reduction: Trees can absorb and dampen sound, reducing noise pollution and creating a more peaceful environment.
Health benefits: Interacting with trees and spending time in natural environments has been shown to have positive effects on mental and physical health, reducing stress, anxiety, and promoting overall well-being.
Australia’s forests are valued for their diverse ecosystems and unique biodiversity. They perform important environmental functions including storing carbon and protecting soil and water. Forests are also significant places with cultural and heritage values. They also provide access to green space used for recreational and relaxation.
Given their numerous ecological and societal benefits, the preservation and responsible management of trees and forests are essential for the long-term health and sustainability of our planet.
Cartoons have been a beloved part of many peoples childhood, entertaining audiences with colourful characters and crazy adventures. One of the enduring aspects of cartoons are the portrayal of animals, which often take on exaggerated characteristics and behaviours. From the lightning-fast Road Runner to the whirlwind Tasmanian Devil, these cartoon animals have captured our imaginations.
While the cartoon Road Runner may be a fictionalized version of this bird, it’s clear that the real roadrunner is a remarkable creature in its own right, perfectly adapted to its harsh desert environment. The cartoon Road Runner is depicted as a blue bird with long brown legs and a dark blue crest on top of its head. Living in the southwest American desert surrounded by cacti, boulders, and sand.
There really is a Roadrunner!
The Greater Roadrunner Geococcyx californianus, the larger of the 2 species for roadrunner measures about 55 cm in length.
Roadrunners have various predators including coyotes. But the coyote can run at 65 km/h which is much faster than the speed of a roadrunner, so would have no problem catching up with one.
The roadrunner will be forever remembered by the sound ‘Meep meep’. Listen below to what they really sound like.
What makes the real roadrunner really remarkable is its adaptability and intelligence. These birds are skilled hunters, preying on insects, lizards, and even snakes. They are also known for their distinctive appearance, with long legs, a crest of feathers on their head.
Another iconic cartoon animal is the Tasmanian Devil, portrayed as a spinning whirlwind of energy and chaos. With its ferocious growl and insatiable appetite, the cartoon Tasmanian Devil is a force to be reckoned with. The real Tasmanian Devil is a unique marsupial found only in Tasmania, off the south coast of Australia.
While it shares some characteristics with its cartoon counterpart, such as its stocky build and powerful jaws, the similarities end there.
In reality, the Tasmanian Devil is a solitary and nocturnal creature, known for its scavenging habits and loud vocalizations.
Unfortunately, the real Tasmanian Devil faces significant challenges in the wild, including habitat loss and Devil Facial Tumour Disease a contagious cancer, which has decimated populations. Efforts are underway to protect this iconic species, including conservation breeding programs and initiatives to control the spread of the disease.
Tasmanian Devil
Cartoon animals may entertain us with their exaggerated antics and larger-than-life personalities, but they often bear little resemblance to their real-life counterparts. While characters like the Road Runner and the Tasmanian Devil may capture our imaginations, it’s important to remember the beauty and complexity of the natural world they are based on. By learning more about real animals and the challenges they face, we can gain a deeper appreciation for the incredible diversity of life on Earth. So whether you’re watching cartoons or exploring the great outdoors, take a moment to marvel at the wonders of the animal kingdom, both real and imagined.
