<a href="https://www.apartments.com.au/developments/crows-nest-nsw-2065">Crows Nest</a> continues to be a hive of activity for developers following the opening of the Crows Nest Metro station nearly two years ago.

The latest Transport Oriented Development plans are located directly across the road from the station, which sees around 6,000 commuters pass through during the morning peak.

A new State Significant Development Application, filed by an entity linked to Colin Rahim and Pierre Sukkar, directors at builder Growthbuilt and emerging developer Prosper, proposes a 40-storey mixed-use tower with 254 apartments on a 2,127 sqm site at <a href="https://www.apartments.com.au/new-apartments/402-420-pacific-highway-crows-nest-nsw-2065">402–420 Pacific Highway</a>.

The development will comprise 40 one-bedroom apartments, 105 two-bedroom apartments, half of which will include an additional study, 101 three-bedroom apartments, and eight four-bedroom penthouses. These will sit above a four-storey podium, with four levels of basement parking providing 148 spaces.

fjcstudio has designed the building, which it says “embodies the principles of Transit Oriented Development (TOD) by promoting higher-density, mixed-use urban living in close proximity to the Crows Nest Metro Station, consistent with the Crows Nest Precinct Design Guide.”

The practice adds that the development supports economic activity, reduces reliance on private vehicles, and enhances the public realm through active ground-floor uses, public domain upgrades, improved permeability, and fine-grain street activation.

“The proposal aligns with the Precinct Vision by contributing to a vibrant mixed commercial and residential centre that integrates housing, jobs, and services while strengthening the local village character of Crows Nest.”

Crows Nest has become one of the most sought-after suburbs for both apartment developers and buyers since the Metro opened in 2024. Developer Third.i quickly sold out half of the apartments at Elevate Hume Place, located directly above the station.

Deicorp recently launched its debut Lower North Shore project, Falcon &amp; Alexander, while Abadeen and Lindsay Bennelong have completed boutique developments in the suburb.

Prosper is also active in Crows Nest, having recently launched Kora, a boutique development of just 10 apartments on Willoughby Road. Its development pipeline has expanded significantly in recent years, following the completion of its luxury Bellevue Hill project, Splendour, in 2024. The group also has plans for a boutique development on Cowan Road in St Ives, as well as a 55-apartment project in Drummoyne.

Private equity real estate firm Conquest is upsizing plans for its recently acquired Quadrangle Shopping Centre in Sydney’s Castlecrag.

Conquest purchased the site for just shy of $70 million last year, with existing plans in place for a mixed-use residential and retail precinct comprising 38 luxury apartments.

Those plans have now been significantly expanded, with the developer lodging a State Significant Development Application with the NSW Government’s Housing Delivery Authority for 150 apartments across two 11-storey buildings. The apartments will sit above a four-storey podium, incorporating specialty retail tenancies and five levels of basement car parking, on the 5,166 sqm site at <a href="https://www.apartments.com.au/new-apartments/100-edinburgh-road-castlecrag-nsw-2068">100 Edinburgh Road</a>.

<img alt="Conquest" data-entity-type="file" data-entity-uuid="581d49cf-7f03-4d17-a864-88700bf1fef1" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-21%20at%208.24.49%E2%80%AFAM.png?VersionId=K1U7nXEFcwuYHEKJwEKlnmtggRb2XjDQ" />

fjcstudio has designed the shop-top housing development, which it says will “deliver a more efficient and future-focused design outcome.”

“The site occupies a strategically significant position within the Castlecrag Local Centre, situated along Edinburgh Road and surrounded by established low-density residential areas and natural bushland,” the studio said.

“The proposal responds to this context through a carefully considered design that integrates built form, landscape, and public domain improvements, while respecting the suburb’s strong landscape and heritage identity.”

<img alt="Conquest" data-entity-type="file" data-entity-uuid="1c170ad2-0a65-43a3-a5de-8bea82b69b11" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-21%20at%208.25.38%E2%80%AFAM.png?VersionId=gqsRHFKAlG7kH4t4Q9rkFWTMpmEbKmI8" />

The architects say the increased height and density are consistent with the NSW Housing SEPP objectives, supporting greater housing diversity and affordability while achieving high standards of architectural and environmental performance.

The proposal also references the draft Willoughby Local Centres Strategy 2036, which aims to promote a network of thriving, attractive and distinctive village centres across the local government area.

“The current trend shows that Castlecrag’s population is set to increase significantly over the coming years. The site falls within the study area for Castlecrag and is in an ideal location for higher density to meet anticipated urban strategy targets at both a state and local level. Aligning with metropolitan strategies, the proposed development will contribute to a more walkable local centre and help meet demand for an additional 1,500 dwellings across Willoughby’s local centres by 2036.”

Of the roughly 1,000 homes in Castlecrag, only around 11 are apartments, according to the latest ABS Census data.

Conquest has been increasingly active in the development space in recent years. The group acquired the Eastlakes Shopping Centre redevelopment, where it plans to deliver more than 1,000 apartments above a new retail precinct, and has also lodged a $900 million State Significant Development Application for a <a href="https://www.apartments.com.au/news/nsw/conquest-unveils-900m-stanmore-village-vision-for-landmark-inner-west-site">mixed-use precinct in Stanmore</a>.

<a href="https://www.apartments.com.au/developers/capital-corporation">Capital Corporation</a> has announced that its <a href="https://www.apartments.com.au/new-townhouses/lovedale-farm-1054-1184-wine-country-drive-lovedale-nsw-2325">Lovedale Farm</a> residential, resort and golf project has secured $24.6 million in sales in just three weeks since the opening of its display home, underscoring the appetite for premium lifestyle property in the Hunter Valley countryside.

The sales milestone has been driven by a diverse mix of buyers, including owner-occupiers and investors from Sydney, Newcastle and the local Hunter region, purchasing both land-only lots and house and land packages across the development.

<img alt="Lovedale" data-entity-type="file" data-entity-uuid="e173edc9-e60e-4f19-a060-9dc4421a3233" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/LovedaleFarm_20250215-1.jpg?VersionId=1LY6CvOaD.Dzrt8tWpWxXtPyfchixNIo" />

&nbsp;

The result builds on the momentum generated at the display home opening on 22 March, which attracted more than 460 attendees.

With house and land pricing from $1.14 million, Lovedale Farm continues to attract strong interest from buyers seeking a premium lifestyle offering at a compelling price point. The development’s vision, a championship golf course, future epicurean village and access to the Hunter Valley’s celebrated wine country, has resonated with a broad buyer profile, from first-time investors to those looking to make the move and call the Hunter Valley home.

<img alt="Lovedale Farm records $21.4 million in sales in three weeks" data-entity-type="file" data-entity-uuid="b358e789-e1eb-40ed-8105-ed5c8297136f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/20260321LovedaleFarmDisplayHomeOpening--6.jpg?VersionId=6GUO8TNnxuELONrsM6n9imDB6oc82Bor" />

Jim Hunter, Managing Director of Capital Corporation said the response since opening the display home has been encouraging.

"To reach $24.6 million in sales in just three weeks speaks to the genuine demand for a lifestyle community of this calibre in the Hunter Valley," Hunter says.

"We’re seeing buyers from across the region and beyond, including investors who recognise the long-term value, and owner-occupiers who simply want to live somewhere truly special.

“Lovedale Farm is two decades in the making, and the market’s response is everything we hoped for. We’re excited to see these first buyers become part of the Lovedale Farm story from the very beginning."

&nbsp;

Spanning 240 hectares on Wine Country Drive in <a href="https://www.apartments.com.au/developments/lovedale-nsw-2325">Lovedale</a>, the $1 billion development is expected to deliver around 1,250 jobs during construction and inject more than $300 million into the local economy. The first 200 homes and championship 18-hole golf course are anticipated for completion in late 2027.

Capital Corporation has also lodged development plans for the Lovedale Farm clubhouse, set to become a vibrant hub for residents and the wider Hunter Valley community. Further releases are planned for later this year.

Lovedale Farm display home opening triggers $24.6 million in sales in three weeks

Prominent Malaysian developer <a href="https://www.apartments.com.au/developers/osk-property">OSK Property</a> has unveiled <a href="https://www.apartments.com.au/new-apartments/aura-at-melbourne-square-7-hoff-boulevard-southbank-vic-3006">Aura</a>, the next stage of its $3.5 billion Melbourne Square precinct in Southbank, continuing its push into wellness-led, amenity-rich apartment living.

The $800 million tower, planned for 7 Hoff Boulevard, will rise 67 storeys and deliver 673 apartments, with COX Architecture drawing on both Japanese design principles and Australia’s natural landscape to shape the building’s identity. A rectangular grid aesthetic defines the building’s exterior, with COX drawing design cues from New York high-rises and Tokyo’s skyline.

Aura builds on a growing trend in high-density living, where wellness is no longer an add-on but central to the product. The development is structured around four key pillars, combining calm, minimalist residences with layered communal spaces, landscaped gardens, and a suite of wellness amenities designed to support both physical and mental wellbeing.

[smartcode_project:default project_id=151921 project_image_fid=367465]

At the core of the project is what OSK describes as a vertical wellness ecosystem, a multi-level approach to amenity that integrates health, lifestyle, and social spaces throughout the building rather than confining them to a single level.

The main resident hub, the Aura Club on level seven, will include a pool, cold plunge, spa, gym, Pilates and yoga studios, alongside more lifestyle-driven inclusions like a golf simulator, music rooms, library, and work-from-home spaces. Above, a series of higher-level amenity zones, including the Meridian Club and Cumulus Club, introduce more refined, social and retreat-style environments, with private dining, lounges, and premium wellness spaces positioned to take advantage of city views.

[smartcode_project:default project_id=151921 project_image_fid=367467]

The residences themselves will largely include balconies, a key design move in a market increasingly focused on natural light, airflow, and connection to the outdoors. Views will extend across the CBD, the Arts Precinct, Royal Botanic Gardens, and beyond.

Aura also introduces approximately 1,600 sqm of retail across the lower levels, further activating the Melbourne Square precinct, which already includes Kennedy Park, a Woolworths, childcare, and a growing mix of hospitality operators.

[smartcode_project:default project_id=151921 project_image_fid=367474]

“Aura stands tall as an exemplar of holistic wellness – its focus on social, physical and mental health culminate in a building that is calming, restorative and relaxing, where residents will have their own sanctuary within the well-connected and sought-after <a href="https://www.apartments.com.au/developments/southbank-vic-3006">Southbank</a>," says&nbsp;OSK Property CEO Chong Boon Woon.

“We have been very encouraged by the market’s response to the BLVD offering, and we know there is a strong demand for the level of amenity, service and design that the Melbourne Square precinct is known for.

“Complemented by work-from-home lounges for professionals, family friendly outdoor garden spaces, and state-of-the-art fitness and wellness facilities, Aura will continue our focus on maximising physical, emotional, and mental wellbeing,” he said.&nbsp;

[smartcode_project:default project_id=151921 project_image_fid=367475]

The project follows the strong performance of BLVD, which is now around 80 per cent sold, and reinforces OSK Property’s long-term commitment to Melbourne Square as a fully integrated, mixed-use precinct.

Construction is expected to commence in late 2026.

OSK unveils AURA, the latest stage in Southbank's $3.5 billion Melbourne Square precinct

National developer Time &amp; Place appears to have settled on a design for its long-anticipated Potts Point project.

After several years of back and forth with local council and the NSW Government, the developer, which has spent seven years targeting the former The Chimes site on Macleay Street, has now progressed its plans.

Following a concept design submission last year by SJB, Time &amp; Place has lodged a full State Significant Development Application with the NSW Government, this time for a scheme designed by Kerry Hill Architects.

<img alt="Time &amp; Place" data-entity-type="file" data-entity-uuid="504d2a27-d65f-4227-8189-1e35e3376e62" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-20%20at%209.38.24%E2%80%AFAM.png?VersionId=_XqFKATYHF30KnVByPxhaI9UBzmkmfn7" />

The 16-storey proposal includes 44 apartments, 21 of which will be build-to-sell. These will comprise 19 three-bedroom apartments and two four-bedroom units.

More than 50 per cent of the development will be dedicated to affordable housing, with 23 studio apartments to be delivered in line with the NSW Government’s Housing SEPP.

Kerry Hill Architects said the proposal is driven by a strong response to place.

“Our proposal for a new residential building for Potts Point in Sydney is driven by a deep consideration of place,” the practice said in its submission.

“This operates on multiple levels, including a landscape approach that reinstates endemic flora of the Sydney peninsula and provides a ground-floor garden for residents, reconnecting the site to its pre-European history. A brick podium further strengthens this relationship to context, integrating planting and fine bronze detailing that references the predominant material language of Macleay Street.”

The three-level podium will be topped by a communal resident space, featuring a covered pool designed to receive direct afternoon sun in winter, a neighbouring reflection pool, dining and event areas oriented to maximise sunset views, and an outdoor exercise zone.

<img alt="Time &amp; Place" data-entity-type="file" data-entity-uuid="8d3eedc1-babb-44a3-bd96-d8a42f3adf1f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-20%20at%209.37.48%E2%80%AFAM.png?VersionId=Ii7.4dvqNatu5GQi6bhqNjAswrMB998." />

The design also incorporates highly crafted shopfronts and a clearly defined residential entry to activate the street. Juliette balconies to the podium residences will provide passive surveillance and a strong sense of habitation.

Above, the larger apartments are housed within a light-coloured masonry and bronze tower.

“The tower steps back in a series of gently curved volumes that reference the rich Art Deco context of Macleay Street,” the architects said. “Carefully calibrated vertical fins frame the views while providing privacy and a sense of refuge.”

<img alt="Time &amp; Place" data-entity-type="file" data-entity-uuid="6fab60f4-3140-4469-b47a-48c781e0a30b" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-20%20at%209.28.44%E2%80%AFAM.png?VersionId=e5XxrM3kzdASdKlcIACHAHbOSZhSKC9O" />

Time &amp; Place has been one of the most active developers nationally in the last 12 to 24 months. Late last year they completed&nbsp;The Queensbridge in&nbsp;<a href="https://www.apartments.com.au/developments/southbank-vic-3006">Southbank</a>, a mixed-use tower with 353 apartments and a hotel. They are currently selling Park Modern, 246 apartments near the famous Botanic Gardens in South Melbourne.

The developer has approval for The Burke, a mixed-use project in&nbsp;<a href="https://www.apartments.com.au/new-apartments/glen-iris-vic-3146">Glen Iris</a>&nbsp;being delivered in partnership with Woolworths. The 60 apartments, positioned above a new Woolworths supermarket, are expected to launch in the coming months. Time &amp; Place is also progressing plans for the redevelopment of&nbsp;<a href="https://www.apartments.com.au/developments/northcote-vic-3070">Northcote</a>&nbsp;Plaza, and have recently submitted plans for a <a href="https://www.apartments.com.au/news/vic/time-place-unveils-plans-22-storey-south-melbourne-tower">22-storey tower</a>, another in South Melbourne.

In&nbsp;<a href="https://www.apartments.com.au/developments/sydney-nsw">Sydney</a>, the developer has two projects in Manly: Two Tides, which is currently under construction, and an ultra high-end building on&nbsp;<a href="https://www.apartments.com.au/buildings/shoreline-manly-beach-89-90-north-steyne-manly">North Steyne</a>, fronting the beach. It is also continuing to work through the redevelopment of The Chimes building on Macleay Street in&nbsp;<a href="https://www.apartments.com.au/developments/potts-point-nsw-2011">Potts Point</a>, as well as Marlborough House, the redevelopment of the original David Jones warehouse building in&nbsp;<a href="https://www.apartments.com.au/developments/surry-hills-nsw-2010">Surry Hills</a>.

Ecosystem

<html><body>
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.

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.

The pink-tailed worm lizard is one of the rare species living in the native grasslands of the Southern Tablelands. <a href="https://commons.wikimedia.org/wiki/File:Pink-tailed_Worm-lizard_(Aprasia_parapulchella)_(9106371285).jpg" target="_blank">Matt Clancy/Wikimedia Commons</a>, <a href="http://creativecommons.org/licenses/by-sa/4.0/" target="_blank">CC BY-SA</a>
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.
