Fresh off completing Pienza Neutral Bay, developer <a href="https://www.apartments.com.au/developers/central-element">Central Element</a> is preparing its next move in the coveted Lower North Shore suburb.&nbsp;

Central Element (CE) has lodged plans for an eight-storey apartment building at <a href="https://www.apartments.com.au/new-apartments/54-64-barry-street-neutral-bay-nsw-2089">54–64 Barry Street</a>, a 1,659 sqm site just south of Military Road and the Neutral Bay town centre.

The $52 million development will involve the demolition of four detached homes across four lots to deliver 45 apartments, including eight affordable housing units to be managed by Bridge Housing. The mix will comprise six one-bedroom apartments, 24 two-beds, and 15 three-beds. The apartments will sit above three basement levels with 62 car parking spaces and 50 bicycle spaces.

<a href="https://www.apartments.com.au/architects/mhn-design-union">MHN Design Union</a> (MHNDU) has returned as architect following its work on Pienza, again shaping a mid-rise form with a clear street presence. The design features a lower four-storey podium element that responds to surrounding context, with upper levels recessed to reduce perceived bulk. Communal open space is proposed both at ground level and on the rooftop, the latter including an outdoor kitchen and swimming pool.

“The building has been designed with a lower four-storey element and with building materials commensurate with the character of the area,” Beam Planning noted in its submission to the North Sydney Council.

Bridge Housing will manage the affordable units for a period of 15 years, as required under the Housing SEPP’s incentive provisions.

MHNDU’s design report further highlights the site's strategic location just 250 metres from key bus stops and 1.3 kilometres from North Sydney CBD, positioning it for transit-accessible housing supply. In their planning justification, the design team emphasised the site’s compatibility with emerging local character and scale.

Central Element has a solid apartment pipeline spread all over Sydney. They recently completed&nbsp;Pienza, 37 apartments just 500 metres away from the new project, and are currently building Ethos Chatswood, Ballamac House in Coogee, and Bianca on the harbour in Drummoyne.

They have plans for future projects in Mosman, Bondi Beach, Greenwich, Lavender Bay, along with a tower on the edge of Hyde Park.

Real estate investment fund Wentworth Wentworth Equities is soon to launch a "Los Angeles-inspired" residential, leisure and lifestyle precinct in Brisbane’s Hamilton riverside ahead of the predicted Olympic-led population explosion for the city.

Drawing its style inspiration and name from Los Angeles’ renowned The Grove, <a href="https://www.apartments.com.au/new-apartments/hamilton-grove-19-hercules-street-hamilton-qld-4007">Hamilton Grove</a> will feature three residential towers and a vibrant street-level public precinct with curated luxury lifestyle, retail and dining offerings.

The first of the three towers, to launch in March 2026, will comprise 61 apartments, in the same building as a premium hotel.<img alt="Hamilton Grove" data-entity-type="file" data-entity-uuid="d227fe61-8392-45b7-b386-9133f29a249f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-01-19%20at%209.10.56%E2%80%AFAM.png?VersionId=HTCV35HZ4h84jQCmHwhsdIPN0ctO5d7Z" />

Wentworth Equities Executive Chairman Sameh Ibrahim said the precinct will be unique in its appeal to both residents and the wider community.

“Hamilton is already one of Brisbane’s most sought-after riverside suburbs and for good reason,” Ibrahim said.

“Where else in the world can you walk out of your front door and have everything you could possibly need at your fingertips? The city is just around the corner, the airport is only ten minutes away, you have the river and green spaces right there and premium retail and dining on your doorstep."

Wentworth Equities acquired the 7637 sqm Hercules St site in 2014, when Ibrahim said he had a "very clear vision" for the precinct, but ultimately it wasn't the right time to develop. He said Hamilton was still very much an "emerging precinct."

“Since then, Hamilton and surrounding suburbs like Ascot and Albion have significantly grown and matured into a precinct that aligns with our vision for Hamilton Grove. Brisbane as a whole has so much to offer in the way of lifestyle appeal, but as it stands it is so widespread – you go to Howard Smith Wharves for fine dining, you go to James Street for shopping, you go to West End to walk along the river – but what if you could go to Hamilton Grove for everything?

“Our vision is a precinct that brings together the best of Brisbane into one central space abundant with culture, class and culinary experience – a place that a lucky few will get to call home, but the rest of Brisbane still get to explore and experience at their leisure.”

"LA-inspired" Hamilton Grove to launch on Brisbane riverside

There’s a quiet patch of <a href="https://www.apartments.com.au/developments/hawthorn-vic-3122">Hawthorn</a>, between the bustle of Glenferrie Road and the curve of the Yarra, that rarely sees change, and even more rarely, new apartments. But that’s exactly where <a href="https://www.apartments.com.au/developers/pomeroy-pacific-quattro-corp">PQD</a> is planting Kooyongkoot: a deliberate, 18-residence answer to the question of what downsizers actually want.

“This is something this pocket of Hawthorn has never seen before,” says Fil Gacesa, head of sales at PQD. “<a href="https://www.apartments.com.au/new-apartments/kooyongkoot-hawthorn-1-kooyongkoot-road-hawthorn-vic-3122">Kooyongkoot</a> will deliver just 18 large-scale apartments in the heart of Hawthorn. It is the true definition of resort-style living.”

That scale is central to the story. It’s what allows for two dedicated lift cores, short corridors, and a generous lightcourt that draws natural ventilation and sunlight into every residence. It’s also what makes room for the sort of amenity usually confined to high-density towers: a fully equipped wellness centre with infrared and traditional saunas, yoga and pilates studio, cold therapy shower, and treatment room. There’s a golf simulator, car and dog wash stations, and extensive storage too, not bolted on, but baked in from the start.

But more than the checklist, it’s the design intent that carries weight. “This project has been many years in the making,” says Mark Pomeroy, Director of PQD. “Not just in planning, but in listening, to what our buyers and the local community are looking for”.

[smartcode_project:default project_id=102717 project_image_fid=355289]

That listening shows up in the materials, oak floors, natural stone, V-ZUG appliances, and in how space is handled. Penthouses feature private rooftop terraces with pools. Terraces and garden residences embrace outdoor connection. Inside, the layouts skew large and open, geared for hosting, not just housing.

Architecturally, <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>’s approach is grounded. There’s no reaching for spectacle here. Instead, the building offers a sculptural calm, anchored by landscaping from Eckersley Garden Architecture.&nbsp;

“We wanted to create spaces that feel expansive, serene, and meaningfully connected to daily life,” said founding partner Chris Stribley elsewhere.

[smartcode_project:default project_id=102717 project_image_fid=355304]

That sentiment, calm, connection, echoes in the location itself. Kooyongkoot sits just a short stroll from Central Gardens, Fairview Park, and the Rivoli Cinema. Tram lines and schools are close, but the street is tucked, quiet, and leaf-lined.&nbsp;

“Residents of Kooyongkoot will be a short stroll from Fairview Park, Central Gardens, and the Glenferrie Road retail strip," Gacesa notes, "but you're also cocooned in this peaceful pocket behind extensive landscaping by Eckersley Garden Architecture.”

Kooyongkoot is set for completion in late 2026.

The project that said no to compromise: Inside Kooyongkoot, Hawthorn

When long-time Ivanhoe locals Graeme and Catherine, decided it was time to downsize, they weren’t necessarily in a rush.&nbsp;

Like many in their stage of life, they had started thinking about apartment living, but anticipated making the shift in two to three years.

That timeline changed when they visited <a href="https://www.urban.com.au/new-apartments/candela-ivanhoe-40-upper-heidelberg-road-ivanhoe">Candela</a>, a new boutique development by <a href="https://www.urban.com.au/developers/salter-brothers">Salter Brothers</a>. The project ticked all the boxes they were looking for: location, quality design, and long-term lifestyle benefits, which prompted them to bring their decision forward.

“It was the right place at the right time,” they said. “We knew immediately it ticked all the boxes, and we didn’t want to wait.”

[smartcode_project:default project_id=342 project_image_fid=358855]

Their decision to downsize was driven by a combination of practical needs and lifestyle considerations. Their existing home, while much loved, had become increasingly difficult to maintain. It spanned multiple levels, included extensive front and back gardens, and was starting to show the wear that comes with age.&nbsp;

They were looking for a more manageable lifestyle, one with less upkeep and more freedom. A brand-new apartment with no maintenance requirements and the ability to simply “lock up and leave” gave them peace of mind and a greater sense of control over their future.

Financially, the purchase made sense as well. The available stamp duty savings, strong price-to-value offering, and timing of the settlement suited their plans, making the transition smoother and more cost-effective. The apartment's design and inclusions further supported their choice.

[smartcode_project:default project_id=342 project_image_fid=357493]

The layout was both functional and flexible: three bedrooms, a butler’s pantry, a separate laundry, and a large open-plan living area. It gave them the freedom to host a family, accommodate guests, or set up a home office. The expansive balcony and elevated views added to the appeal, providing a sense of openness and connection to the outdoors.

“It just had a really good flow,” Catherine noted, something they found lacking in many other apartments they’d considered, particularly in the established market.

Candela’s boutique scale was another deciding factor. With a smaller number of residences and a top-floor penthouse position, the couple felt the development offered the privacy and space they were looking for, without feeling isolated.

“We liked that it wasn’t a huge development. It felt well-balanced, modern but still with a sense of community, not overwhelming,” they said.

[smartcode_project:default project_id=342 project_image_fid=357508]

Equally important was the ability to remain in Ivanhoe, a suburb they know well and have deep roots in. After 46 years in the area, proximity to local parks, shops, and familiar faces mattered just as much as the apartment itself.

“We didn’t want to give up the community we’ve known for decades. Candela allowed us to upgrade our lifestyle while staying in the place we call home.”

With a Walk Score of 90, the village location supports a convenient, connected lifestyle. <a href="https://www.apartments.com.au/developments/ivanhoe-vic-3079">Ivanhoe</a> Station is just a eight-minute walk away, and the neighbourhood offers access to parks, cafes, restaurants, and schools along Upper Heidelberg Road, all within easy reach.

Beyond the apartment, the couple also saw value in the broader vision for Candela, one that integrates residential living with public spaces and local amenities.&nbsp;

The development introduces 58 new apartments as well as a mix of commercial and social spaces that integrate contemporary architecture with the suburb’s existing character.&nbsp;

At ground level, residents will find a charming café and a lifestyle wellness centre, perfect for unwinding and rejuvenating. Meanwhile, the rooftop garden offers a stunning vantage point for residents to enjoy breathtaking sunsets, host gatherings, or enjoy barbecues with family and friends. It's not just a place to live; it's a vibrant community where every moment is an opportunity to connect and create lasting memories.

Why Ivanhoe locals are choosing to downsize to Candela

Mark and Roy Makari are expanding their presence in Sydney’s South West with a second major proposal for Leppington, this time envisioning a 900-dwelling mixed-use development just 850 metres from their previously lodged tower trio on Fifth Avenue.

Project management and construction management firm Creative Vision filed the plans for the&nbsp;multi-building project at <a href="https://www.apartments.com.au/new-apartments/230-rickard-road-leppington-nsw-2179">230 Rickard Road, Leppington</a>. The proposal seeks to establish a new focal point for the precinct through a high-density, transit-oriented development supported by diverse land uses.

According to the Scoping Report prepared for the Department of Planning, the scheme includes around 900 apartments across multiple towers, including 135 dwellings designated for affordable housing. A mix of market and subsidised apartments will be supported by ground-level activation through retail and office space, a childcare centre, and a hotel, forming a comprehensive urban precinct.

<img alt="Mixed Use Development 230 Rickard Rd Leppington" data-entity-type="file" data-entity-uuid="34797362-f3dc-4d84-8235-2657fc5f3bde" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Plan.png?VersionId=Uzckrz9tUpDQl5lX1_WMhjnv16bsr8wG" />

The Design Report by <a href="https://www.apartments.com.au/architects/studiosc-0">Studio SC</a> notes that the project “intends to deliver a high-quality, high-density built form that supports the vision for the Leppington Town Centre, integrating mixed-use outcomes and public domain upgrades.” The development is expected to be delivered in stages, although a precise timeline is yet to be confirmed.

The project will be assessed through a future State Significant Development Application, with the Scoping Report indicating the team will seek design excellence via a competitive process or through an expert design review panel. Early massing diagrams suggest a series of mid- to high-rise buildings framing a central landscaped spine, with emphasis on pedestrian permeability and public space.

The planning documentation flags a strong sustainability agenda, stating that the development will “respond to the urban heat island effect, incorporate water sensitive urban design, and prioritise active transport”.

<img alt="Mixed Use Development 230 Rickard Rd Leppington" data-entity-type="file" data-entity-uuid="369d7b54-1279-4cde-88ec-dcb215594414" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Podium_1.png?VersionId=QArL7B2kkLt63vl5xvL0FNV_ardAlez4" />

The proposal follows in the footsteps of the Makaris’ nearby Fifth Avenue site, where they’ve submitted plans for three towers comprising nearly 500 apartments, with 10 per cent dedicated to affordable housing. That project features commercial podiums, a childcare centre, and a new public park that would occupy more than a third of the site.

Both developments are situated within walking distance of Leppington Train Station and fall under strategic precinct plans promoting higher density housing. The town centre is undergoing substantial transformation, driven by state government planning reforms aimed at fast-tracking housing delivery.

Together, the two projects represent a combined ambition of nearly 1,400 new homes across just under two kilometres of central Leppington.

Ecosystem

As the east coast bushfire crisis finally abates, it’s easy to see nothing but loss: more than 11 million hectares of charcoal and ash, and more than a billion dead animals.
But it is heartening to remember that bushfire can be a boon to some plants and animals. We’re already seeing fresh green shoots as plants and trees resprout. Beetles and other insects are making short work of animal carcasses; they will soon be followed by the birds which feed on them.
Australia’s worsening fire regimes are challenging even these tolerant species. But let’s take a look at exactly how life is returning to our forests now, and what to expect in coming months.
<img src="https://images.theconversation.com/files/315625/original/file-20200217-10985-gmpykj.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">
Life is returning to fire-ravaged landscapes. Flickr, <a class="license" href="http://creativecommons.org/licenses/by/4.0/" target="_blank">CC BY</a>
<h2>The science of resprouting</h2>
Of course, bushfires kill innumerous trees – but many do survive. Most of us are familiar with the image of bright green sprouts shooting from the trunks and branches of trees such as eucalypts. But how do they revive so quickly?
The secret is a protected “bud bank” which lies behind thick bark, <a href="https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.12001" target="_blank">protected from the flames</a>. These “epicormic” buds produce leaves, which enables the tree to photosynthesise – create sugar from the sun so the tree can survive.
Under normal conditions, hormones from shoots higher in the tree suppress these buds. But when the tree loses canopy leaves due to <a href="https://www.nature.com/articles/ncomms1191" target="_blank">fire</a>, drought or insect attack, the hormone levels drop, allowing the buds to sprout.
<h2>Insect influx</h2>
This summer’s fires left in their wake a mass of decaying animal carcasses, logs and tree trunks. While such a loss can be devastating for many species – particularly those that were already vulnerable – many insects thrive in these conditions.
For example, <a href="http://forensicentomologist.com/wp-content/uploads/2008/06/4.pdf" target="_blank">flies</a> lay eggs in the animal carcasses; when the maggots hatch, the rotting flesh provides an ample food source. This process helps break down the animal’s body – reducing bacteria, disease and bad smells. Flies are important decomposers and their increased numbers also provide food for birds, reptiles and other species.
Similarly, <a href="https://theconversation.com/wood-beetles-are-natures-recyclers-with-a-little-help-from-fungi-76029" target="_blank">beetles</a> such as the <a href="https://www.anbg.gov.au/gardens/visiting/exploring/fauna/insects/beetles-ANBG" target="_blank">grey furrowed rosechafer</a>, whose grubs feed on decaying logs and tree trunks, add nutrients to the soil when they defecate which helps plants grow again.
<a href="https://www.sciencedirect.com/science/article/abs/pii/S0378112705003130" target="_blank">Insects also benefit</a> from the mass of new leaves on trunks and branches. For example, native <a href="/news">psyllids</a> – an insect similar to aphids – feed on the sap from leaves and so thrive on the fresh growth.
<img src="https://images.theconversation.com/files/315623/original/file-20200217-10985-k5e7fc.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">
Animal carcasses are a sad consequence of bushfire, but provide a boon to some insect species. Sean Davey/AAP
<h2>Then come the birds</h2>
Once insects start to move back into an area from forested areas nearby, the birds that eat them will follow.
An increase in psyllids encourages honeyeaters – such as bell miners and <a href="https://ro.uow.edu.au/cgi/viewcontent.cgi?article=1145&amp;context=thsci" target="_blank">noisy miners</a> – to return. These birds are considered <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378112705003130" target="_blank">pests</a>.
A <a href="http://www.publish.csiro.au/pc/PC970221" target="_blank">CSIRO study</a> after bushfires in Victoria’s East Gippsland in 1983 found several native bird species – flame and scarlet robins, the buff-rumped thornbill and superb fairy-wren – increased quickly to levels greater than before fire. As shrubs in the understorey regrow, other species will move in, slowly increasing biodiversity. 
Since the recent <a href="https://www.nbnnews.com.au/2019/11/12/watch-and-act-bushfire-burning-in-moonbi-north-of-tamworth/" target="_blank">bushfire in woodland near Moonbi in New South Wales</a>, numerous bird species have returned. On a visit over this past weekend, I observed currawongs landing in the canopy, saw fairy wrens darting in and out of foliage sprouting from the ground, and heard peep wrens in tufts of foliage on bark and high branches.
Honeyeaters moved between burnt and intact trees on the edge of the blackened forest and butterflies visited new plants flowering after recent rain.

The presence of the currawong, while a pest species, shows birdlife is returning to the bush. Flickr, <a class="license" href="http://creativecommons.org/licenses/by/4.0/" target="_blank">CC BY</a>
<h2>Weeds can help</h2>
<a href="https://www.propertyobserver.com.au/https://www.sciencedirect.com/science/article/abs/pii/0006320795900616" target="_blank">Weeds</a> usually benefit when fire opens up the tree canopy and lets in light. While this has a downside – preventing native plants from regenerating – weeds can also provide cover for native animal species.
A study I co-authored in 2018 found highly invasive <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1442-8903.2011.00600.x" target="_blank">Lantana camara</a> provided habitat for <a href="https://www.publish.csiro.au/AM/AM17003" target="_blank">small mammals</a> such as the brown rat in some forests. Mammal numbers in areas where lantana was present were greater than where it was absent.
<a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-3180.2011.00869.x" target="_blank">Lantana</a> often grows quickly after fire due to the increase in light and its ability to <a href="https://link.springer.com/article/10.1023/A:1009707404802" target="_blank">suppress</a> other plant growth.

<h2>Is there hope for threatened species?</h2>
Generalist species – those that thrive in a variety of environments – can adapt to burnt forest. But specialist species need particular features of an ecosystem to survive, and are far less resilient.
The critically endangered <a href="https://books.google.com.au/books?hl=en&amp;lr=&amp;id=hF2sMDVZztIC&amp;oi=fnd&amp;pg=PR7&amp;ots=5Uri8BWkcm&amp;sig=UKvmQHpO-9hWvqK5pYEfB6hSIEU&amp;redir_esc=y#v=onepage&amp;q&amp;f=false" target="_blank">Leadbeater’s possum</a> lives only in <a href="https://www.wildlife.vic.gov.au/our-wildlife/leadbeaters-possum" target="_blank">small pockets of forest</a> in Victoria.
It requires large fires to create a specific habitat: big dead trees provide hollows for shelter and nesting, and insects feeding on burnt wood and carcasses provide a food source.
But for the Leadbeater’s possum to benefit from the fire regime, bushfires should be infrequent – perhaps every 75 years – allowing time for the forest to grow back. If fires are too frequent, larger trees will not have time to establish and hollows will not be created, causing the species’ numbers to decline.
Similarly in NSW, at least 50% and up to 80% of the habitat of threatened species such as the vulnerable rufous scrub-bird was burnt in the recent fires, an environmental department analysis <a href="https://www.environment.gov.au/biodiversity/bushfire-recovery/research-and-resources">found</a>.
<h2>Looking ahead</h2>
Only time will tell whether biodiversity in these areas is forever damaged, or will return to its former state.
Large fires may benefit some native species but they also provide food and shelter for predatory species, such as <a href="https://theconversation.com/hunter-hunted-when-the-world-catches-on-fire-how-do-predators-respond-126280" target="_blank">feral cats and foxes</a>. The newly open forest leaves many native mammals exposed, changing the foodweb, or feeding relationships, in an ecosystem.
This means we may see a change in the types of birds, reptiles and mammals found in forests after the fires. And if these areas don’t eventually return to their pre-fire state, these environments may be changed forever – and extinctions will be imminent.

These plants and animals are now flourishing as life creeps back after bushfires

<html><body>
GUEST OBSERVATION
Coalition minister Angus Taylor is under scrutiny for possibly intervening in the clearing of grasslands in the southern highlands of New South Wales. Leaving aside the political dimensions, it’s worth asking: why do these grasslands matter?
The grasslands in much of eastern Australia are the result of forests and woodlands cleared to “improve” the landscape (from a grazier’s point of view) to make it suitable for grazing livestock.
The “improvement” typically entails cutting trees, burning the felled timber and uprooting tree stumps, followed by ploughing, fertilising and sowing introduced grasses that are more palatable to livestock than many native grasses.
However, largely treeless native grasslands once occurred at high elevations across much of the Monaro tableland, in the area stretching between Canberra and Bombala.
The Monaro grasslands (or in scientific speak, the <a href="http://www.environment.gov.au/biodiversity/threatened/conservation-advices/natural-temperate-grassland-southern-tablelands" target="_blank">natural temperate grassland of the Southern Tablelands</a>) are in relatively dry and cold areas, particularly in upland valleys or frost hollows where cold air descends at night.
The combination of dry climate and cold restricts tree growth and instead has encouraged grasses and herbs. Native grasses such as kangaroo grass and poa tussock dominate the grasslands, but there are many other unique plants. A typical undisturbed grassland area will support 10-20 species of native grasses and 40 or more non-grass species.
The grassy plains are also home to unique cold-adapted reptiles such as the grass-land earless dragon, little whip snake, pink-tailed worm lizard and striped legless lizards. This combination of plants and animals create a unique ecological community.

A fraction remain
It is estimated <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1442-8903.2007.00363" target="_blank">only 0.5%</a> of the area that would once have been natural temperate grasslands in the Southern Tablelands remains. The rest has been gradually “improved” <a href="https://www.propertyobserver.com.au/https://trove.nla.gov.au/work/11035501?selectedversion=NBD25432907" target="_blank">since the mid-nineteenth century</a> to make them more productive for livestock grazing.
Livestock dramatically change the composition of grasslands, as animals remove palatable plants and compact the soil under their weight. Disturbed soil and the livestock also help to <a href="https://www.propertyobserver.com.au/https://trove.nla.gov.au/work/11035501?selectedversion=NBD25432907">spread non-native weeds</a>.
However, most native grasslands have not just been modified by grazing but completely replaced by man-made pastures. That is, the land has been ploughed, fertilised and the seeds of introduced grasses have been planted.
These changes to the landscape mean much of the landscape is dominated by introduced plants and is now unsuitable for many of the native plants and animals that once lived and grew there.
Because the Natural Temperate Grassland of the Southern Tablelands is now so rare it is <a href="https://www.environment.nsw.gov.au/threatenedSpeciesApp/profile.aspx?id=20260" target="_blank">classified as critically endangered and federally protected</a>. Furthermore, many of the <a href="http://www.environment.gov.au/biodiversity/threatened/conservation-advices/natural-temperate-grassland-southern-tablelands" target="_blank">distinct plants and animals</a> that still live in these grasslands are classified as vulnerable or endangered.

Some of the best remaining examples of the Monaro grasslands can be found in old cemeteries and in areas set aside as public livestock grazing areas. These areas of public land have often been spared from pasture improvement or only lightly grazed, and thus now support relatively intact native grassland ecosystems.
While, to the untrained eye the Monaro grasslands may seem unremarkable and difficult to distinguish from grazing pastures, they are deeply important. They show us what Australia once looked like, and act as a haven for native biodiversity.
Indeed, what remains of the natural grasslands is now so disturbed by agriculture there is a real threat this distinctive ecological community and many of the species it contains may disappear altogether, if they are not protected from excessive grazing, fertilisers and the plough.<img src="https://counter.theconversation.com/content/121181/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">

GUEST OBSERVER
Fish are the most threatened group among Earth’s freshwater vertebrates. On average, freshwater fish populations have declined by 76 percent over the past 40 years. Damaged fish communities and declining fisheries characterise global freshwater environments, including those in Australia.
Fish migrate to complete their life cycles, but water-resource developments disrupt river connectivity and migrations, threatening biological diversity and fisheries.
Millions of dams, weirs and smaller barriers – for storage and irrigation, road and rail transport and hydropower schemes – block the migration of fish in rivers worldwide.
These barriers serve our needs for water supply, transport and energy. But, by obstructing fish migrations, they also degrade ecological integrity and reduce food security.
This is bad news for those who depend on fish for food. For example, in the Mekong River fish supply over 70% of the people’s animal protein, but catches are falling drastically following dam building.
In our paper published today in CSIRO’s Marine and Freshwater Research, we take stock of the impact these barriers have on our freshwater fish, most (perhaps all) of which migrate, and how we can help them.
<h2>Dam it all</h2>
There are countless barriers across Australia’s rivers. Roughly 10,000 barriers of all kinds obstruct flows in the Murray-Darling Basin. Flow is unobstructed in less than half of the basin’s watercourse length.
Native fish numbers in the basin’s rivers have declined by an estimated 90% through habitat fragmentation by barriers together with altered flows, overfishing, coldwater pollution and invasive species.
Similar problems also affect coastal river systems. One or more barriers obstruct 49% of rivers in southeast Australia.
Local species extinctions and loss of biodiversity have occurred nationwide in developed regions, especially upstream of large dams.
<h2>Overcoming barriers</h2>
One way to help fish overcome barriers is to build fishways (or “fish ladders”).
Fishways are designed to aid fish travelling upstream or downstream at high (dams, weirs) or low (road crossings, barrages) barriers. These are classed as “technical”, with hard-engineering designs, or “nature-like”, mimicking natural stream channels.
Recognition that dams threaten freshwater fish communities lagged well behind their construction. Nonetheless, European and American observations of declining fisheries for species moving from the sea to breed in rivers prompted early attempts in Australia to provide for fish passage.
The first Australian fishway was built near Sydney in 1913. By 1985, 52 had been built, but they adopted Northern Hemisphere designs for salmon and trout. These were unsuitable for Australian species, which rarely leap at barriers, and their flow velocities, turbulence and other aspects were excessive.
Seeing the failure of these fishways, New South Wales Fisheries sought advice in 1982 from George Eicher, an American expert, who advised on research to create designs for local species.
This led to expanding fishways research and construction in eastern states. The result was markedly improved performance, for example in the Murray-Darling’s Sea to Hume program.
<h2>Fishway performance</h2>
Our research shows that regrettably few Australian fishways have yet been shown to meet ideal ecological criteria for mitigating the impact of barriers. Furthermore, fishways are in place at relatively few sites.
In NSW, for example, only about 172 in total serve several thousand weirs and 123 dams. They can be expensive to build and operate, so costs retard mitigation at numerous important sites.
Fishways have seldom been built on dams (fewer than 3% of Australia’s 500 high dams have one); they have generally cost tens of millions of dollars; and most operate, with limited effectiveness, for less than 50% of the time. The need for much greater investment in innovation, research and development is pressing.
<h2>How to store water and also rehabilitate fish</h2>
To reduce the impact of dams on fish we need to look at resolving problems at river-basin scale; improving our management of barriers, environmental flows and water quality; removing barriers; and developing improved fishway designs.
One way to accelerate improvements nationally would be to pass legislation for routinely re-licensing waterway barriers at regular intervals. This would mean that older barriers are re-evaluated and upgraded or removed where necessary. Under the NSW Weir Removal Program, 14 redundant weirs have already been removed, with others under assessment.
We are developing an innovative pump fishway concept at UNSW Australia. It combines aquaculture fish-pumping methods for safe fish transfer with existing fishway technology.
We hope the project may help transform past practices through less-costly modular construction, adaptability to a wide range of barriers and improved effectiveness.
Better fishway developments will mean that we can store and supply much-needed water while also restoring fish migrations. This will be increasingly important as climate change reduces streamflows in many regions, and will help rehabilitate fish populations.
