Two dead street trees right next to each other in Marrickville – notable because they are beside each other.

My last post was about the NSW government’s ‘Five Million Trees’ initiative.  See – https://bit.ly/2H2IEkz    The aim is to increase Sydney’s existing tree canopy from 16.8% to 40% over the next 12 years at a cost of $37.5 million over four years.

Fortune had it that I came across a long & detailed article from Scenario Journal titled, ‘How Many Trees Are Enough? Tree Death and the Urban Canopy’ written by Lara A. Roman.  https://bit.ly/2K1G1gC

The article looked at tree survival across US cities.  Research has found that, despite concentrated campaigns to increase the urban canopy in many major US cities, the canopy cover is actually declining. This is of major concern considering the extra pressure we have from increased development, a changing climate & its associated urban heat island impacts.

Three questions were asked –

  • “With major new planting campaigns, how many of those trees will survive for decades, reaching a mature size at which their environmental and socioeconomic benefits are greatest?
  • How many trees are enough – that is, how many need to be planted to make a lasting impact, and meet a city’s canopy cover goals?
  • What are the implications of future tree death for managing the urban forest, in terms of cycles of tree removal and replacement?”

“For street trees in New York City, eight to nine years after planting, 26.2% were dead.  For a yard tree give-away program in Sacramento,  five years after planting, 29.1% had died, on top of 15.1% that were never planted by residents.  For these yard and street tree examples, over a quarter of the trees planted died within the first five to nine years, and furthermore, for the tree give-away, some trees never made it into the ground.”                                                 

As part of their 5 Million Trees initiative the NSW government plans to give away 15,000 trees to people who are building homes in new land release areas in Western Sydney.  I wonder how many of these trees will actually be planted.  I don’t know about you, but I have bought plants from the nursery & left it too long before I put them into the ground.   One can realistically expect that high numbers of these giveaway trees will not be planted in western Sydney.  Will these be acknowledged, or will they just be written up as a successful addition to the urban canopy simply because they were given away?

The Inner West Council has given away trees for the past two National Tree Days & I applaud them for this.  It would be interesting to know whether Council has gathered information about how many of these trees made it into the ground & how many are still alive today?

The article notes that in the US there is very little in regards to monitoring & follow-up with tree planting campaigns & calls for a nationally coordinated monitoring network.

The author then cites the common belief that street trees live on average for only 7-years & a maximum of 13-years. Apparently, this belief was formed decades ago where a questionnaire was sent to urban foresters “asking the local experts to estimate the typical tree lifespans in their cities.”  The author describes this as “overly pessimistic.”

One only need to look around our own suburbs to know that there are plenty of streets with street trees that are 70-100 years of age.  Generally, these are QLD Brushbox or Fig trees.

A study to understand the change in the street tree population of West Oakland in the US looking at annual tree planting & tree deaths found that the annual mortality rate was 3.7%.   Most of the tree loss came from newly planted trees with a trunk of 7.6cms (3 inches).

“Extra vigilance during the establishment phase, in terms of maintenance and stewardship, might have the most payoff for ensuring planting survival, and thus achieving larger canopy objectives.”

“Planting a few hundred trees, or even a million, does not automatically translate into an increase in the overall tree population over the long-term. To increase population levels, the survival and planting rates have to out-weigh losses from tree death and removal, including both old and young individuals.”

I think this article brings up serious issues concerning increasing the urban forest.  I’ve noticed that street tree removals post Marrickville Council’s Tree Inventory meant that for at least 3-4 years the urban forest numbers stayed relatively the same.  With 1,590 streettrees to be removed from 2013, planting around 400 new trees a year meant that making up ground was slow.

I have noticed that a lot of street trees have been removed in the last couple of years.  Since Council does not report the removal of trees 5-metres or under & since 49% of our street trees were found to be 5-metres or under, we have no idea where street tree numbers are at now & no ability to calculate this ourselves.  The Tree Inventory was costly, so I doubt we will have a new one done for many years.

Increasing the canopy means not the number of trees planted, but the percentage of total ground area; for example, at 50% canopy cover, half of the total ground area is covered by the vertical projection of tree crowns.”  

This has an impact on the way Council prune street trees as well. Continuing to remove side branches that serve to make the tree canopy fuller & produce longer periods of shade is counterproductive – unless it is required for safety reasons like branches over the road affecting passing trucks as an example.  However, you only need to look at the street trees around you to know that many street trees are pruned to have no side branches.

Council’s policy of no tree branches 2.5-metres (8.2 feet) above a footpath pretty much ensures that the footpath will have no shade except for perhaps an hour when the sun is in the right position.

The Five Million Trees initiative may result in significant changes with tree planting & reporting.  It would be good if this information is available to the community should they be interested.  Hopefully, outdated ways to manage street trees get dumped & our urban landscape becomes green & flourishing.

Fatima Island jusst holding on.  

One of two new trees planted close to the edge of the rover bank in Kendrick Park. These will provide nice shade & food for wildlife.  Discovery Point Wolli Creek looms over us.  The wide angle lens flattens the height making the buildings seem less imposing than what they are.  Building has not finished yet.  

Last weekend we took a bike ride from Mackey Park to Kendrick Park & on to Tempe Reserve.  For various reasons, it has been a number of months since we last visited  Tempe Reserve.

It was great to see two new trees planted close to the riverbank at Kendrick Park.  These will replace the trees removed back in 2011 that were in this position.  Shade here will improve the amenity of the park, as well as add beauty & habitat/food for wildlife.

Looking across to the ever-increasing development at Discovery Point Wolli Creek is perhaps a look at the future for Marrickville & Dulwich Hill.  I certainly find it strange to recreate under the eyes of so many just across the river.  I think this is something we are all going to have to get used to.

It was also wonderful to see that all the new trees planted near to the Princes Highway at Kendrick Park are growing well & have not been vandalised.  This is unusual these days.

Unfortunately, Fatima Island is holding on by a thread.  There are perhaps three trees left.  Personally I feel sad that this island is likely to be lost.  It is a wonderful refuge for waterbirds & only one of two places along the Cooks River where you can always see them when the tide is low.

Ofo bike tossed in the Cooks River.

OFO bike placed in a tree at Tempe Reserve.  Not good for the bike and definitely not good for the tree.

Once we got to Tempe Reserve we saw three yellow OFO Bikes in the river & another high up in a fig tree.  Seeing these bikes in the river has become more prominent than shopping trolleys.

Council’s planting around the picnic kiosks on the western side have grown well & quite a few Casuarina trees have opportunistically popped up, which is not a bad thing in my opinion.  There is plenty of room for more trees in this park.  The other area of new trees and understorey opposite the kiosks beside the ‘turpentine forest’ is also doing well having filled out considerably.

This pole has had a large section removed from the top and has been bound with steel straps.

Further along the mystery of the split habitat pole was solved.  See – https://bit.ly/2pxSQH2

It was an unintentional split & Council has wrapped many steel bracings around the pole to fix this.  I will be very interested to see if any wildlife does set up home in the hollow attached to this pole.   Perhaps this has already happened.

The bottom of the National Tree Day 2015 site is not doing well.

However the top section has shown some progress.

The 2015 National Tree Day site is showing progress.  The bottom part has not done well, but the area at the top has & the 5 trees planted have all survived & are growing.   You can compare by seeing past photos here – https://bit.ly/2IOf2EK

The WestConnex Authority is drilling at Tempe Reserve for the M5 extension

The WestConnex Authority are onsite & have cordoned off a section of the park & the basketball courts to drill & store their equipment.  This is not the first time I have seen them drilling here.  I think it is felt by the majority of this community that it will be a terrible loss & impact on green space if the motorway runs through or over Tempe Reserve.

I am so happy to see this beautiful fig tree doing so well after its roots were exposed by erosion.  The plantings  by Sydney Water are doing well.

The wonderful work done by Sydney Water to restore the river bank as the Cooks River becomes the Alexandra Canal is looking good.  The sedge plantings on the riverbank wall are growing well, as well as all their other plants around the trees.  Importantly, the beautiful Fig tree whose roots were exposed to the air & the brackish water of the river is looking very good after being helped.

Sedge planting in the new riverbank wall built by Sydney Water.  It was low tide when I took this photo.

National Tree Day site in Steel Park Marrickville South. All that is wood chip is the new area that was planted today. It joins last year’s site to create a continuous corridor along the river in this area.

This afternoon we went down to Steel Park Marrickville South to have a look at Inner West Council’s National Tree Day site.  I had looked at the site earlier & noticed just how big the area to be planted is in comparison to previous years.  Inner West Council decided to convert a significant area into habitat for wildlife at this location &  I think this is excellent.

Three new trees were planted –

  • Two Swamp mahoganies (Eucalyptus robusta), an Australian native that can reach up to 30-metres in height. It can live for at least 200-years.  I find exciting to have such long-lived trees planted in a park where it has a decent opportunity to reach such an age.  Fingers crossed anyway.   It flowers well in spring & summer & offers food for birds & other nectar-eating wildlife.  Christmas beetles like to eat the leaves, so hopefully we will see some of these at Steel Park.
  • One Prickly-leaved paperbark (Melaleuca styphelioides) – also an Australian native. This is a medium-sized tree that reaches between 5-11 metres in height.   It has a dense, rounded canopy with drooping branchlets & produces cream or white cylindrical bottlebrush-like flowers in summer.  It likes to grow along stream banks or other moist situations, so good for this location.

Everyone who planted today have done the whole community a service & I thank them.   It is excellent to see more places along the river that are for wildlife only & I personally, think that looking at bushy areas is far more interesting than great expanses of lawn.  The birds will come, which adds a further layer of enjoyment to users of the park.

A closer look. Each dark patch is where something was planted.

What a positive change to this section of Unwins Bridge Road. Street trees and verge gardens on both sides of the road!

In May 2017 I posted about the new verge gardens created along both sides of Unwins Bridge Road from Tramway Street to the corner of Gannon Street Tempe. See – http://bit.ly/2r7xu1O

I was hopeful that street trees would be planted too.   Well, my wish was granted.  Not only has Inner West Council planted street trees, but they planted a lot of them in just one block.  I think this is the largest number of new trees planted in one block that I have noticed since starting this blog.

Twelve Ornamental pear trees have been planted on the eastern side & seven on the western side of Unwins Bridge Road. This is the species Council are planting along Unwins Bridge Road.

You may have noticed that many of our high traffic roads are lined with Ornamental pear trees.  I think it is because they are so robust & can tolerate poor growing conditions.  They create a fairly dense canopy, so will provide a good pollution barrier between the traffic & the houses collecting some of the particulate matter from passing vehicles.   They should also help muffle some of the traffic noise & cool the street as well.

The trees will also add beauty to this section of Unwins Bridge Road that was previously dominated by concrete for what seems like forever.  The change is quite striking even at this early stage after planting.  Imagine how it will look once everything has grown.

Council has planted a variety of plants from native grasses to native violets & other small plants.  These too will help manage air pollution, add beauty & cool the area down.

I applaud Council for doing this work & for choosing to plant street trees in that location.  The trees will work to improve the air quality for local residents who have to tolerate massive amounts of traffic passing by seven days a week & the associated pollution.

If all our heavy traffic roads could also have the same treatment, this will help improve the health of the residents now & into the future.  More & more research is finding that street trees have a considerable impact on the health of the community, so the more our urban forest increases, the better it will be for all of us.

Showing the western side of Unwins Bridge Road.

Quite a range of plants in the verge gardens.

One of two new Sydney red gums. The shade from these two trees, once they have grown, is expected to cover “at least three-quarters of the car park.”  

This area is permeable paving, yet people can walk on it without experiencing problems or noticing a difference.

I was impressed when I read that the Inner West Council had planted two advanced size Sydney Red Gums (Angophora costata) at the Garners Avenue car park in Marrickville as part of an upgrade.

Council Administrator Mr Pearson said in Council’s Press Release, “When mature, these trees will provide canopy cover to at least three-quarters of the carpark.  So, instead of the usual unshaded bitumen and concrete which would increase the inner west’s ‘urban heat island effect,’ we are actually contributing shade, cooler ambient air temperatures, and improved urban air quality.”  

Council’s Press Release makes mention that shade not only increases amenity, but also increases “the serviceable life of the bitumen by up to 30%.”   

The trees were planted in structural vaults, which on the surface look like business as usual, but are actually purpose built to provide optimum living conditions for a tree planted in unnatural conditions.

The surface is covered by permeable paving allowing rainwater to get to the tree.  Below ground, the area for the tree to grow has been prepared by placing good-quality soil in structural cells across a large area.  The structural cells provide room for the roots to grow, but also encourages them to grow in preferred directions.

Better soil, access to water & room to spread allows the tree grow to maturity.   This technique is light years better than digging a hole in the pavement & planting a tree.  It is well worth the money Council needs to spend on this planting style.

Council’s Press Release (http://bit.ly/2qwAt49 ) made many favourable statements regarding public trees.  It appears we can expect to see a positive change in our urban forest.

“Trees usually come second to infrastructure such as footpaths, roads and car parks. But Inner West Council is determined to turn this thinking around.”

I visited the Garners Street carpark & saw the two Sydney red gums.  They look great.  The flowers from these trees will provide food for bees, butterflies & nectar-eating birds.

I was also impressed to see three new Banksias planted in a small garden area toward the back of the car park.

Two other good sized Diamond leaf pittosporum (Auranticarpa rhombifolia) growing on the other side are festooned with orange berries at present.  These are Australian native rainforest trees & their orange berries attract fruit-eating birds.

The addition of Australian native trees that can grow to a significant size is a big & positive change from the current Purple Leaf Ornamental Plum (Prunus nigra) & Evergreen ash (Fraxinus griffithii) planted at the front of the car park.

I like what Inner West Council have done here.  Give the trees a few years to grow & the difference will be noticeable.  The more Council can plant decent sized native trees in areas traditionally covered with concrete & bitumen the better.  Changes like this will have positive impacts on the livability of our area.   I thank Council for doing this work.

New planting of three Banksias and other plants.

Illawarra Flame tree - just one of the free trees available.

Illawarra Flame tree in flower – just one of the free tree species available.

Great news & a first for ex-Marrickville Council, now the Inner West Council.

On National Tree Day, Sunday 31st July 2016, Council will be giving away free trees so that we can be a part of increasing our urban forest canopy & all the associated benefits trees bring to both the community & the wildlife.

Unfortunately, Council does not say how many trees will be in the giveaway, so if you want one, I recommend getting there earlier rather than later.

Tree species available are –

  • Sydney Red Gum/ Smooth Barked Apple (Angophora crostata)
  • Coast Banksia (Banksia integrifolia)
  • Old Man Banksia (Banksia serrata)
  • Illawarra Flame Tree (Brachychiton acerifolius)
  • Bottlebrush (Callistemon viminallis cv)
  • Black Tea-Tree (Melaleuca bracteata)
  • Lemon-scented Tea Tree (Leptospermum petersonii)
  • Riberry (Syzygium leuhmannii)

Information about these trees can be found in Council’s pdf document, which includes photos – http://www.marrickville.nsw.gov.au/Global/Environment/In%20your%20community/Tree%20management/treegiveaway/treespecies.pdf

Council staff will be available to talk about the trees available to help you decide which species is best for your property & provide planting & caring advice.

WHEN:  National Tree Day – Sunday 31st July 2016.

WHERE:  The car park at the back of the Debbie and Abbey Borgia Centre in Steel Park Marrickville South.  Council says, “The trees will be advanced sized stock (25 litre bags/300mm pots), so please make sure you can accommodate this size tree when picking it up.”

TIME: 10am – 1pm.

IMPORTANT:  There is a limit of one tree per household. You will need to provide proof of your address in the form of a Council rates notice or Drivers Licence.

New street trees in Alice Lane Newtown

New street trees in Alice Lane Newtown

Very large rain garden in  Alice Lane Newtown

Very large rain garden in Alice Lane Newtown. Photo was taken 2 months ago, so it should be looking better now.

The new high-rise housing development on Alice Street is nearing completion.  I am pleased to see that all the street trees have been protected.  It was nice to see the shadow pattern of dappled leaves over balconies knowing that whoever lives there will look out onto the canopy of these trees & enjoy the shade, green & birdlife.  My bet is the outlook onto mature trees will be used as a selling point.

Behind this building in Alice Lane I counted 20 new trees planted as part of the development.  One species looks to be Banksia with another species planted with every alternate tree.

At the corner of Pearl Street & Alice Lane they (I am assuming this work was done by the developers) have built a large rain garden.  It looks great & will only improve as the plants grow.  It is obvious that planning has included making it an informal meeting place where people can sit & chat.

On the wall of the house that sits beside the rain garden in a very nice nature-themed mural painted by @mulgatheartist.  The outlook is ‘groovy tropical’ with Australian native birds looking hip wearing sun glasses.  It’s sweet, funny & a bit whimisical.  I like it a lot & I especially love that it is nature-themed.

Improvements like this help with stormwater & clean the water before it reaches the Cooks River, even from this far away.  The raingarden, new trees & mural also help soften the landscape, plus add beauty & a patch of habitat in a hard landscape.

Street art by @mulgatheartist.  I love it.

Showing the location of the playground and the river

Council plans to plant vegetation in front of  the riverbank to stop the community having access to the river – yet this is where many sit to enjoy a picnic with friends, read a book, chill out & watch the river.  The fence you can see carries on for many metres past following the path & keeps children from running from the playground to the path or the river.  It should be enough.  Why should the community miss out on being able to sit beside the river?  There are so few places where we can do this along both sides of the river without having a fence, mangroves or something in front to prevent this.  I find this part of the plan very sad & hope Council changes their mind.

 

Continuing on from my posts on Mahoney Reserve. See – http://bit.ly/210uG1I

Steel Park is also a ‘designated fauna habitat link.’

Inner West Council (nee Marrickville Council) plan the following for Steel Park –

  • Add more concrete paths to help with existing desire lines & increasing recreation opportunities.”  One will be a 1.8-metre wide path to Thornley Street from the current shared path along the grass next to the cliff up to Thornley Street. Our Council loves laying concrete in parks.
  • What is good is the plan for new trees around the flying fox, the water play park & between the play facilities & the ball net. New trees also for around the exercise equipment & the proposed water treatment wetland. New trees are also planned for the slope near Thornley Street.  It would be nice to know the number of trees planned, but any new trees are a boon for this park.
  • All the Poplar trees except for those in the Children’s Playground will be removed. I think this is entirely unnecessary, especially removing healthy trees for the reasons given & in these days of climate change when trees are more important than ever.  It will be an expensive job to remove 27 big tall trees.  You can read more here –  http://bit.ly/1Wlfe1x
  • The lower branches of the Casuarina trees along the foreshore pathway will be removed to increase sight lines & ground covers planted.
  • Grasses, groundcovers & small shrubs will be planted alongside residential properties.
  • Grasses & groundcovers to be planted beside the car park.
  • New rain gardens a minimum 2-metres wide will be added to the car park & planted with local native sedges, grasses & tree plantings.
  • 13 new seats will be placed along the edge of Illawarra Road & behind the Debbie and Abbey Borgia Recreation Centre.
  • 5 concrete “block style” seating will be placed in the patch of grass near the house on the slope next to Thornley Street.
  • There will be another barbeque installed next to the playground with a shade structure.
  • The playground will be expanded with new equipment that has a nature based theme.  That’s nice.
  • The fence around the northern playing field will be removed.
  • New bike racks installed near the exercise equipment.
  • Upgrade the playing field with new turf & drainage.
  • And sadly, Council plans to plant vegetation infront of the river  “to limit water access by users.” 
 I would have thought the extensive fence between the shared path & the children’s playground & barbecue areas would have been sufficient.  Frankly, the plan to cut off access to the river makes me feel sad.  To stop people being able to sit at or near the river’s edge is a BIG LOSS to many in the community.   Plenty of people like to sit here on picnic blankets & watch the river.  

Community consultation is open until this Wednesday 8th June 2016.  You can access the link at ‘Your Say Marrickville’ & download the Plan here – http://bit.ly/1DRISiO

A 1.8-metre wide path will be installed on the left of the photo to the trees in the distance & up the slope to Thornley Street.

I love memorial trees.  To me they represent life, beauty & a celebration of the life of the person who has passed.  I know that memorial trees are very healing for people who have lost someone they love.

I am excited to see that finally we can choose to have our cremated remains become part of a new living tree, but only in Victoria at the moment.  Let’s hope this concept spreads Australia-wide.

The Greater Metropolitan Cemeteries Trust in Melbourne is introducing ‘The Living Legacy’ program at all of its nineteen Melbourne cemeteries.  The program will allow people to have their cremated ashes turned into fertilizer.  See – http://bit.ly/1Tq1Oin

“The product will be incorporated into the root ball of existing trees so the person who has passed literally becomes part of the tree.   How lovely is that.

Not only will one tree be planted to commemorate the death of a person – “a further 200 will be donated to create urban forests in cities in Australia & overseas.”

The trees will be planted by

The trees planted in Australia will be planted by ‘Greenfleet’ an Australian non-profit environmental organization.  Greenfleet also have a carbon offset program where you can donate to have your carbon footprint offset with new trees planted in reforestation projects around Australia.  See – http://bit.ly/15RsP9A

Melbourne man Warren Roberts came up with the idea of ‘The Living Legacy’ program after the death of his best friend.  “He said he was not able to properly grieve her death for years until he spent time out in gardens, parks and forests, which was when he came up with the idea.” 

Because cremated ashes are toxic to plants Mr Roberts spoke to a number of experts.  He met & formed a professional relationship with scientist Dr Mary Cole who, over a period of two years, developed a method to transform cremated remains into fertilizer & the concept became a reality.

Not only will this program help grieving people.  It will also help reforest Australia, provide habitat for wildlife & help mitigate climate change.  Another bonus is that Australia’s cemeteries are running out of space.

Costa Georgiadis, host of ABC’s TVs ‘Gardening Australia’ is the ambassador for ‘The Living Legacy’ program.  He says, “If we can connect with the longevity of trees, then the baton that we hand to the next generation is spiritually significant.”   I like that.

I got a pleasant surprise when I drove down Unwins Bridge Road last weekend.  Marrickville Council has been very busy planting 20 ornamental pear trees all along the west side of the road all the way to Tillman Park.   It looks like there will be three more trees to be planted, as it appears there are three areas prepared for them.

If any road needed street trees this section of Unwins Bridge Road was it.  I am hoping that the other side also gets trees.

Street trees will help purify the air in this high traffic road, which will be much better for the health of the residents, the school children from the primary & high school & the many pedestrians.  The trees will also add beauty, green & shade to the streetscape.

A big thank you to Marrickville Council from me.

All the new trees look like this one.
