Government must ensure all Canberrans can the share benefits of our urban forest

It’s better late than never, but government moves to ensure blocks have enough land reserved for the trees that will shield homes from the scorching summer sun, cool backyards and provide relief to the eye is more than welcome.

Part of the recently released Urban Forest Strategy, the proposed 15 per cent minimum, championed, it must be said, by the ACT Greens, will go a long way to stopping the infamous building out of blocks in new suburbs such as Coombs and in inner areas where the demolish-and-rebuild is popular.

Standing cheek by jowl, some new homes occupy almost entire blocks with little room for greenery and a big dependence on air conditioning.

They may rack up the energy efficiency stars, but with more clever design to stop wasted space, proper orientation and green buffers, these Canberra castles could be more hospitable and environmentally friendly.

Home-owners should listen more to their architects and builders who often fail to convince them of the merits of less is more.

It’s a pity that the government, Labor that is, has taken so long to come to this view because the legacy will be a swag of new suburbs that will be less treed than they should be, which will have ramifications for how they will cope with a warming climate and the general amenity.

City Services Minister Chris Steel was very keen to shine the spotlight on developers, flagging measures to deter them from bulldozing trees, but the government, through the Suburban Land Agency, is also one of the city’s biggest developers.

Coombs and Wright

Coombs and Wright, for example, have the lowest coverage in the ACT at a mere 1 per cent. You would expect it to be low, being still in development, but the government will have to do a lot of planting on public land to get it up to at least the 30 per cent mark it is aiming for as an average across the Territory.

Nonetheless, putting a price or value on trees will make developers think twice about felling trees, particularly mature ones, and more about incorporating them into their plans and seeing them as assets, not liabilities.

While the established urban forest needs to be maintained, the government is right to prioritise areas of low coverage, for practical reasons and equity.

Every Canberran deserves to live in a leafy suburb, not just those fortunate to live in the inner south or north.

The Strategy calls for 450,000 trees to be planted across the ACT over the next quarter-century but says the urban forest will change as new, more resilient species are deployed and more diverse plantings are encouraged.

The themed streets of the past may not be repeated, and plantings will be more determined by the current climatic conditions rather than simply the seasons.

This will take a mind shift for many people used to the treed order of things in Canberra, but as long as plantings continue to be a mix of deciduous exotics, which provide the greatest shade in summer while allowing the winter sun to filter through the canopy, and natives, it should be a good result.

But the government is also hoping to recruit the community to the cause, calling the forest project a collaborative effort, with an eye on the sheer cost of it all. It wants residents to contribute more than they currently do to maintenance, such as watering.

This may be a challenge and something the government will have to work at. While understandable, it should not rely on it for a successful outcome because the urban forest is far too important to the capital.

It has to be said that the government is playing catch-up, being warned by ANU scientist Cris Brack in 2019 that a failure to act could see whole streetscapes dying.

The Greens’ Caroline Le Couteur said at the same time that the government needed to plant 7,000 trees a year for the next decade just to restore Canberra’s urban forest to its former state.

This year 9,000 trees will be planted, and it will be interesting to see what the appetite is in coming budgets.

If anybody is looking for the benefits of having the Greens in government, then the action on trees is proof.

A couple of things,

1, the greens have been part of the ACT gov for 16 of the last 20 years. Let’s not hold all the blame for a Labor.

2, the new suburbs built under this labor greens gov don’t have room along the streets for real trees. There is barely enough room for cars to park. Suburbs like Coombs and most of Gungahlin will never have the canopy cover of the inner north or inner south

Acton Acton 3:06 pm 10 Apr 21

The simple fact is that the Greens/Labor policy of urban densification and apartmentalisation is totally incompatible with an urban forest. Can these people not understand that more buildings means less trees? Greens/Labor are either (1) dishonest, or (2) deluded, or (3) hypocritical, or (4) cynical, or (5) a combination of 1-4. They must assume their trusting and blinkered supporters will keep on voting for them without noticing that there are less and less trees to hug.

    JC JC 4:55 pm 10 Apr 21

    The alternative being more urban sprawl which has similar effects.

    Ps suggest you take your own blinkers off, they would appear to be foggy or have damaged your eyes.

    Acton Acton 9:14 pm 10 Apr 21

    JC – it would not have a similar effect, because an expansion of housing area would be onto open denuded non-forested former farmland. In time, more trees would be planted in suburban gardens. The Greens/Labor policy of urban densification reduces the urban tree canopy, raises city temperatures by reducing shade, discourages birdlife, raises prices for new home buyers by withholding land for sale and condemns people to poorly build cramped apartments. Use facts and common sense instead of unquestioning loyalty to parties that act more in the interests of corporate developers than the citizenry.

    chewy14 chewy14 8:40 pm 11 Apr 21

    Acton,
    What you’re saying is simply false.

    It is perfectly achieveable to have both urban densification and an urban forest. You achieve this by building taller buildings which then require less ground area which can be used to plant more trees.

    And that’s without even considering how you can use shared spaces and other areas to similarly increase tree coverage.

    As for your claims about Urban Sprawl not increasing tree coverage, there’s nothing to stop the government similarly planting trees on that open farming land right now, so the point is moot.

    Acton Acton 7:20 am 12 Apr 21

    Your claim that building more high rise apartments will create more trees is one if the most bizarre statements I have ever read and typical of the warped thinking of property developers. You seem unaware or unconcerned that under the hypocritical Greens/Labor government their policy of urban densification has coincided with a real drop in the Canberra urban tree canopy from 30% to 21%. Facts not fantasy. The evidence is all around you if you remove those ideological blinkers. More apartments = Less trees. Suburban gardens, leafy streets, parks and geen spaces are what we need and desire, not a concrete jungle of multi-storey apartments and high rises with a few token trees struggling to survive in compacted patches of gloom.

    chewy14 chewy14 10:16 am 12 Apr 21

    Acton,
    Suggest you reread my comment because you clearly didn’t grasp what I was saying.

    I didn’t say the current government’s approach would lead to more tree coverage, we actually have very, very few high rise apartments and the planning laws are not adequate.

    I said, it’s perfectly achievable to have urban densification and good tree coverage through more true high rise apartments rather than less. Because they can be built to take up less total ground area for the same density which would then be used for increased tree plantings around these buildings.

    The problem isn’t densification, it’s how it’s being done.

    I also note that you haven’t proposed a workable alternative, urban sprawl will not result in an increase in trees either.

    This idea of a low density utopia simply doesn’t match with reality because Canberra is no longer the little country town of 30-40 years ago that you are seemingly pining for.

The government seem to be equalising the tree coverage by removing as many trees as possible from the inner suburbs. Hundreds of trees have been removed around Currong Street in Civic and it continues recently with street trees in Ainslie Ave being unnecessarily removed.

Chris Kellow Chris Kellow 8:10 am 10 Apr 21

The bush capital is what tempted me to move to Canberra from rural NSW. I’m still a farm kid at heart and love the trees that we have. Was disappointed when the Northbourne Avenue trees were cut down for the light rail. They were the first ting your saw when I visited Canberra as a kid on the 70s.

    Ashley Wright Ashley Wright 4:57 pm 10 Apr 21

    Chris Kellow those trees have since been replaced. And interestingly of you first saw them in the 70’s the. They weren’t the trees cut down for light rail. Since the 70’s those trees have been replaced twice already. Though maybe not as noticeable as it was done slowly.

And not just street after street of gum trees

“Part of the recently released Urban Forest Strategy, the proposed 15 per cent minimum, championed, it must be said, by the ACT Greens, will go a long way to stopping the infamous building out of blocks in new suburbs…”

More likely, following Kriso Hadskini’s observation earlier today, it will go a long way to increasing the sales of fake grass in Canberra – a product which would be banned by a government that took this issue as seriously as it takes, for instance, the climate impact of gas appliances and plastic straws and cutlery.

A re-worked, re-badged (no one will notice….) version of the much scoffed at “million trees” policy might help, as might policies which recognise (e.g. through a rebate on annual rates) the considerable costs which some residents are bearing as a result of current tree policies. All we have at present are policies which give obsessive levels of protection to trees which meet arbitrary size criteria – with an obvious incentive for homeowners (who do not wish to be caught by such rules) to ensure that no tree on their block ever reaches the size to gain protection.

Eristicus Eristicus 1:51 pm 09 Apr 21

The tree strategy calls for 900,000 trees to be planted from the start of 2020 until the end of 2045. Half for replacements and half for new trees. That’s about 100 trees each for the foreseeable future. The 450,000 in this article is a gross underestimate.

So they build urban wasteland suburbs without enough room for a potplant on the tiny blocks.

David Field David Field 9:39 am 09 Apr 21

If you look at photos of the inner north and inner south from 50 years ago there wasn't much tree coverage then either. Trees do need time to grow...

Jessica En Bee Jessica En Bee 8:57 am 09 Apr 21

Anyone’s welcome to the 2 enormous gums outside my place. Roots invade the drains, costing thousands a year. A bit of thought to planting away from infrastructure would be great. Falling dead branches are dangerous and it took over 2 years to get anyone to come and assess them. It’s not just as easy as planting trees and admiring their beauty.

    Graeme Jackson Graeme Jackson 2:51 pm 09 Apr 21

    Jessica En Bee If you can spot any damage particularly at forks in the main trunk ie from cockatoos, document them with pics. Similarly for any branches crashing down. Took about 10 years but I won on one overhanging my carport and house.

Rainer Busacker Rainer Busacker 8:54 am 09 Apr 21

All developments/developers must be held accountable that their projects include the planting of appropriate trees. Government should be involved to ensure that this is done and the right trees planted. Unfortunately owners have been known to remove/kill the trees on their footpaths.

Where trees are removed by government there is a tendency to replace like for like and this includes gum trees. Education and a new approach is needed.

Gay McGuire Gay McGuire 8:47 am 09 Apr 21

Please no more gum trees!

    Shan Weereratne Shan Weereratne 5:19 pm 09 Apr 21

    Gay McGuire, concur. Gum trees are destructive, depressingly ugly and lack any greenery. Nothing worse for the streetscape with Gum trees strewn all over. They maybe natives but are nasty !!

Kriso Hadskini Kriso Hadskini 8:34 am 09 Apr 21

People need to plant out their backyards too. In newer suburbs its always just fake grass. It is ok to plant trees in your front and backyards. Tree roots are not that big a deal.

Meg Joy Meg Joy 8:10 am 09 Apr 21

I truly hope they will replace the many dying gums with deciduous exotics, which give the best 'bang for buck' in Canberra suburbia by far

    Lyn Christie Lyn Christie 10:29 am 09 Apr 21

    Meg Joy why not some natives. Sick of oak and london plane.

    Nick Anderson Nick Anderson 11:01 am 09 Apr 21

    Lyn Christie it’s the wrong climate for the Tasmanian Fagus tree. With Canberra’s warming climate, the future seems to be native evergreens like the Kurrajong.

    Meg Joy Meg Joy 11:31 am 09 Apr 21

    Lyn Christie Eucalypts, lovely as they are, are generally unsuitable in Canberra suburbs if you are serious about cooling the city from a heat sink perspective. Unfortunately, gum trees (a) provide minimal shade due to self/preservation technique of angling leaves in summer (b) are not deciduous, thus preventing much needed sun access in winter (c) are a monoculture tree, inhibiting growth of grass of other plants underneath (d) are dangerous due to tendency to drop large branches unexpectedly (e) are not a good choice economically - they are often more short lived than suitable deciduous exotics, which means they need attention and replacement more often therefore costing more overall (f) they shed all year, causing continual issues for road safety and residents. It was a huge mistake to plant so many gums in the 70s. Many have since died and it is a far wiser choice to replace with suitable long lived deciduous exotics that will actually make our city beautiful and cool

    Lyn Christie Lyn Christie 11:35 am 09 Apr 21

    Nick Anderson certainly happy with natives. Agree not gums. Meg just mentioned deciduous. 🙂

    Lyn Christie Lyn Christie 11:41 am 09 Apr 21

    Meg Joy the fagus isn't a gum from what I can see. Agree , gums are not my favorite tree in suburban setting. But all we seem to plant is oak (great way to twist ankle) and the plane (great for hayfever).

    Meg Joy Meg Joy 12:38 pm 09 Apr 21

    Lyn Christie I can understand that. Thankfully there are many other suitable deciduous varieties

    Raelene Davies Raelene Davies 1:33 pm 09 Apr 21

    Lyn Christie or having a bike accident from a plane tree's roots pushing up and breaking the bike path and waking up in Calvary Hospital...

    Mirja Spannari Mirja Spannari 4:15 pm 09 Apr 21

    Meg Joy yep get rid off the old dyeback gum on my nature strip with a beautifull maple.

Louise Anne Louise Anne 8:02 am 09 Apr 21

A little bit too late I think. The concrete “legacy” is already here.

Lin Van Oevelen Lin Van Oevelen 7:58 am 09 Apr 21

Too late for lots of recent developments indeed. I live in one and it's a very inhospitable environment in summer. Just a big concrete heat trap.

Our suburb doesn't even have an oval.

Timmy Holness Timmy Holness 7:20 am 09 Apr 21

Planting trees in the right place is so essential especially as our planet warms up. Not gums as they are too messy and oil based

Deciduous is better for this task as it shields during summer and lets light in during winter. Did you know that growing trees produce more oxygen and suck up more carbon dioxide than established trees? So getting a trees that grows slowly would also be great and longer lasting
