Biodiversity Month: Every Species Matters

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.

Why is Biodiversity Important?

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.

    World Water Day

    Today is World Water Day, the 22 March highlights the importance of freshwater. The day is used to advocate for the sustainable management of freshwater resources. This years theme is “Groundwater – making the invisible visible” and explores the importance of groundwater.

    Worls water day 2022 graphic

    Water covers 75% of the earth’s surface, however only a very small amount is freshwater that can be used directly by people, animals and plants because:

    • 97% of this water is in oceans and is too salty for people, animals or plants to use
    • 2% is frozen at the north and south poles, in glaciers and on snowy mountain ranges
    • Only 1% is avaiable as freshwater in rivers, lakes and groundwater.

    Groundwater is invisible, but its impact is visible everywhere. Our drinking water and sanitation, our food supply and natural environment–all these rely on groundwater.

    Groundwater is critically important to the healthy functioning of ecosystems, such as wetlands. In deltas and coastal areas, groundwater also ensures the stability of the ground and prevents seawater intrusion under the land.

    Groundwater is invisible, but its impact is visible everywhere.

    Under our feet, groundwater is a hidden treasure that enriches our lives. 

    Almost all of the liquid freshwater in the world is groundwater.

    As climate change gets worse, groundwater will become more and more critical. 

    We need to work together to sustainably manage this precious resource.

    Groundwater may be out of sight, but it must not be out of mind.

    How to be Waterwise

    Water is essential for all life and is the most abundant substance on Earth, yet water scarcity is one of the biggest issues facing us today. Australia is the world’s driest inhabited continent and 2019 was the hottest and driest year on record

    The Urban Water Cycle

    The natural water cycle has been modified by people to ensure a constant water supply and the safe disposal of wastewater. The Urban Water Cycle incorporates the Water Supply System, Wastewater system and the Stormwater system.

    Why is Water Important

    Water is the most common substance found on earth, so why is it important? Water is essential for all forms of life and can dissolve nearly anything. It can exist as a gas (water vapour and steam), a liquid (water) and a solid (ice).

    World Wetlands Day

    World Wetlands Day is celebrated on 2 February every year. It is time for everyone to understand the importance of wetlands. This years theme is ‘Wetlands Action for People and Nature’. It’s an appeal to invest financial, human and political capital to save the world’s wetlands from disappearing and to restore those we have degraded..

    Why are Wetlands important for Biodiversity?

    Wetlands are important because 40% of the world’s plant and animal species live or breed in wetlands. Over 100,000 freshwater species have been identified in wetlands. Wetlands absorb and store water and help remove pollutant from our water.

    Did you know?

    • Coastal wetlands are among the most biologically diverse places on earth
    • Coral Reef and Mangrove forest protect coastlines from storm surges
    • Wetlands are vanishing three times faster than forests with 35% disappearing since the 1970s.  The causes of wetland loss include:
      • Drainage and infilling for agriculture and construction
      • Pollution
      • Overexploitation of resources including overfishing
      • Invasive species
      • Climate change

    Since 1970 populations of fish, birds, mammals, amphibians, and reptiles have declined by 60%. There has also been a decline of 81% of inland wetland species and 36% of coastal and marine species. A staggering 25% of wetland species are considered to be threatened with extinction, including water birds, freshwater dependent mammals, marine turtles, and coral reef building species.

    Wetlands are areas of land saturated or flooded with water permanently or seasonally. 

    There are amazing wetlands to explore in the middle of Sydney.

    Sydney Olympic Parks is an urban oasis connecting people with nature.  This is a great place to explore to understand the importance of wetlands for biodiversity.

    Frog Walk

    The Frog Walk takes you to frog ponds, frog underpasses and even frog fencing at Wentworth Common and Kronos Hill. You can also visit the Brickpit Ring Walk too see the most significant habitat for the endangered Green and Golden Bell Frog. Remember healthy frogs are an indicator of healthy ecosystems.

    Narrawang Wetland

    Meander along walking paths and a reed-fringed boardwalk to observe the habitat that supports a colony of the endangered Green and Golden Bell frogs and other frog species.

    Badu Mangrove Boardwalk

    Stroll the winding timber boardwalk in Bicentennial Park and you’ll discover surviving riverside wetlands that shelter colourful waterbirds plus the largest mangrove forest remaining on the Parramatta River.

    Waterbird Refuge at Bicentennial Park

    Walk up to the Waterbird Refuge  significant
    waterbird habitat with a high abundance and diversity of resident and migratory birds. Together with the surrounding mangrove forest, the wetland is listed as a ‘Wetland of National Importance’ by
    the Commonwealth Government because of its high ecological values.

    Where does the rain go?

    If you are on the east coast of Australia at the moment you have probably noticed that there has been a lot of rain. The high volume of rain is inundated catchments across the New South Wales resulting in repeated major flooding.

    Multiple heavy rain events lead to super saturated soils and result in swollen river systems. There isn’t enough time for the water to flow away before more rain arrives. The ground is already saturated and can’t absorb more water resulting in increased runoff.

    In many cities and towns this is made worse by hard surfaces; like roads, gutters, pathways and concrete drains. These hard surfaces make efficient channels directing the water into already flooded systems.

    Typical Catchment

    Catchments have water flowing into creeks and rivers and eventually to the sea. Floods in coastal systems are also impacted by the tides. A flood peak coinciding with the high tide will have greater impacts on low lying areas.

    What is a Catchment?

    Why floods are so deep and dangerous in the Hawkesbury-Nepean Valley. Learn how the ‘bathtub effect’ makes this valley have one of the greatest flood risks in Australia.

    The extent and depth of flooding is influenced by the unique ‘Bathtub Effect’ of the floodplain causing floodwater to back-up. The ‘Bathtub Effect’ enables dangerous, damaging flooding of significant depth to occur. 

    Most river valleys tend to widen as they approach the sea. The opposite is the case in the Hawkesbury-Nepean Valley. The river narrow downstream at sandstone gorges between Sackville and Brooklyn create natural choke points. Floodwaters back up and rise rapidly, causing deep and widespread flooding across the floodplain. Much like a bathtub with five taps turned on, but only one plug hole to let the water out.

    World Wetland Day

    Celebrating 50 Years of the Ramsar Convention on Wetlands. This years theme is ‘Wetlands and Water’, highlights the role wetlands play in: clean water.

    World Wetlands Day is an international day celebrated each year on 2 February. The 2 February marks the anniversary of the signing of the Convention on Wetlands of International Importance in Ramsar, Iran, in 1971.

    The Ramsar Convention

    The Ramsar Convention aims to halt the global loss of wetlands and to conserve those that remain through wise use and management. Worldwide there are more than 2,400 listed wetlands of international importance.

    In Australia there are 66 Ramsar sites wetlands of international importance covering about 8.3 million hectares. These sites include iconic wetlands such as Kakadu National Park, Roebuck Bay, Gippsland Lakes, Moreton Bay, Blue Lake, Macquarie Marshes and the Coorong.

    Australia was one of the 5 founding nations to sign the Convention. In 1974 we designated the world’s first Ramsar Wetland, the Cobourg Peninsula in the Northern Territory. Australia continues to play an important role helping to manage and implement the Convention, within Australia and internationally.

    Wetlands are areas of land saturated or flooded with water permanently or seasonally. There are a variety of wetlands including:

    • Inland wetlands: marshes, peatlands ponds, lakes, rivers, floodplains, swamps, fens
    • Coastal wetlands: saltwater marshes, estuaries, mangroves, lagoons, coral reefs
    • Human-made wetlands: fish ponds, reservoirs, saltpans

    The Natural Water Cycle

    The natural water cycle shows the constant movement of water around the world. Water moves through the processes of evaporation, transpiration, condensation, precipitation, run-off, infiltration and percolation.

    The Urban Water Cycle

    The natural water cycle has been modified by people to ensure a constant water supply and the safe disposal of wastewater. The Urban Water Cycle incorporates the Water Supply System, Wastewater system and the Stormwater system.

    Why is Water Important

    Water is the most common substance found on earth, so why is it important? Water is essential for all forms of life and can dissolve nearly anything. It can exist as a gas (water vapour and steam), a liquid (water) and a solid (ice).

    Coastcare Week

    I’ve been working on education resources for the Junior Landcare Learning Centre and was excited to be able to contribute to this years Coastcare Week campaign.

    Coastcare Week is on between 7 – 13 December and Summer up with Coastcare is the 2020 campaign. The campaign aims to raise public awareness of the effects of litter on our waterways, encouraging all Australians to get connected to their local environment with Coastcare, and support groups to continue their invaluable work.

    To recognise Coastcare Week find out ways you can help clean up your local marine environment.

    • At the beach, keep on the walking tracks. This protects the vegetation that provides habitat for local native birds and other animals, and prevents erosion.
    • Ensure your dogs are kept on a lead in areas where dune vegetation is vulnerable.
    • Landcare and Coastcare groups work on these sites to enhance the habitat for native animals to protect them.
    • Avoid and Reduce – by reducing your plastic footprint, you are helping to protect our rivers and waterways that will keep our beaches and oceans clean and protect marine animals from the impact of rubbish including plastics.
    • Reuse – if you need to use plastic products, make sure you reuse items over and over again before disposing of them thoughtfully at the end of their useful life.
    • Recycle – if you can’t reuse an item or if it is at the end of it’s useful life, recycle it or compost it.
    • Make sure you take a bag with you to the beach to collect rubbish on your next walk.
    • Every piece of plastic removed from the marine environment can save an animal’s life, and reduce the amount of microplastic created.

    World Oceans Day

    World Oceans Day is celebrated on 8 June. The theme for World Oceans Day 2020 is “Innovation for a Sustainable Ocean.” The Marine Environments is divided up into three main ecosystems; Oceans, Coral Reefs and Estuaries.

    There are the five major oceans that cover the world including the Atlantic, Pacific, Indian, Arctic, and Southern Oceans. Coral reefs are small in size when compared to the oceans, but around 25% of marine species live in the coral reefs ecosystems. Estuaries are areas where rivers and streams flow into the ocean. This area where freshwater and saltwater meets, creates an ecosystem diverse plant and animal life often called the ‘nurseries of the sea”.

    Our oceans make up 71% of the earth’s surface and they contain the greatest diversity of life on Earth. Habitats range from the freezing polar regions to the warm waters of the coral reefs, deep sea hydrothermal vents to shallow seagrass beds and beautiful sponge gardens to giant kelp forests, marine organisms are found everywhere.

    World Environment Day

    World Environment Day is celebrated every 5th of June and the theme for 2020 is Celebrating Biodiversity. Biodiversity is the variety of life on Earth. It encompasses the 8 million species on the planet including plants, animals, fungi and bacteria. Biodiversity is also the diversity ecosystems across the globe, oceans, forests, alpine regions and coral reefs.

    Biodiversity is at risk, we are losing species at a rate 1,000 times greater than at any other time in recorded human history. Over one million species face extinction. 

    Species diversity is the variety of species within an ecosystem or a region. In Australia, more than 80% of plant and animal species are endemic, which means that they only occur naturally in Australia. We usually notice mammals, birds, fish, reptiles and frogs, but they actually make up less than 1% of all animal species.

    What can you do to help Biodiversity in your Backyard?

    Attracting birds to your backyard

    Attract birds to your backyard by creating a garden that will provide food, shelter and nesting materials and sites. Local flowering plants and fruit trees provide birds with nectar and seeds. To provide birds with some protein rich food, use mulch to encourage worms, insects and grubs to thrive. Plant dense prickly native shrubs for shelter, hang up nesting boxes and install a bird bath.

    Create a frogs friendly backyard

    Encourage frogs to come to live and breed in your backyard. Create a small shallow pond in an area that is partly shaded. Include thick ground hugging plants around part of the pond to provide areas of warmer and cooler water. Your pond will need some sunlight to encourage algae and other plants that provide food for tadpoles. Make sure the banks slope gently so that the frogs can get out. Add some rocks and logs to provide shelter for adult frogs.

    Minibeasts in your backyard

    Not all bugs are pests. Good bugs pollinate plants, break down dead flora and fauna, aerate the soil and provide for other wildlife. They can even help keep harmful pests away. Create an inviting environment for good bugs by planting plenty of native plants, wildflowers and herbs and use chemical-free pest control when the pests do creep in.
