Community tree preservation groups Save Our Figs Wauchope & Save Our Figs Group have a big fight on their hands with Port Macquarie-Hastings Council who intend to remove 13 Fig trees in the town centre “to prevent future damage to private property & public infrastructure.” The roots of the Fig trees are presenting a trip hazard & 3 residents have complained of damage to their property they say was caused by the trees.

These 2 massive Figs next to Marrickville Youth Resources Centre enhance the building & the area.

Thing is, the Council have just completed major works on the streets with the trees described as the centerpiece.  Importantly, 3 years ago the community fought to retain these trees & won.

Now the threat of litigation has reared its head & if history is anything to go by, a very small number of people are going to get their way & have the trees removed.  Council can’t take the risk that people will start litigation in the future.

A couple of days ago I posted that Goondiwindi Regional Council chopped down healthy Fig trees despite community opposition.  It’s the same story.  Now that the trees are gone, the Council has made the decision to spend $96,000 on floating footpaths.  They are doing this now because they, “understand how important these trees are to residents.”

Using floating footpaths means the trees can grow normally. There is no need to cut off or shave down roots, nor cover them in bitumen.  Nor will they need to chop the trees down because of a trip hazard or damage to footpaths. Seems like sensible spending to me.  Given that any large healthy tree can be worth around $100,000, spending money to keep them is a good economic decision.

This Fig is literally holding the building up. There is no visible damage to the exterior of the building

The large street trees in the centre of both these towns are what bring beauty & a sense of place. The towns use their street trees as a tourist draw card.  The Fig trees also provide a tangible history & are held dear by most of the community.

Take the trees away & you have substantially changed a place. Not only have you removed things that are worth a great deal of money & with 13 Figs we are talking in excess of a million dollars, but their loss will have an impact on spending in the shops. Researchers have concluded 11% more money is spent in shopping areas where there are big healthy shady trees.  To their credit Port Macquarie-Hastings Council plans to replace the Figs with 11 advanced Brush Box trees.

My question is why don’t Councils or organizations take pre-emptive action on their big trees when the trees are in areas that could damage property or cause trip hazards?  Ultimately it is worth the financial outlay when one considers how much these trees are worth in a monetary sense. Then there are all the other factors to take into consideration, history, place, future, community cohesion (fights like these in small towns could escalate into severe divisions), trust in the Council/organisation & stating the obvious, climate change.

These roots have infiltrated a parking area. I found it interesting is to see that the roots didn't travel far from the tree despite its size. It has been like this for years & the tree is still healthy even though cars park on the roots, proving it is unnecessary to remove a tree when this happens. It might look unsightly, but the tree itself is gorgeous.

Root barriers can be put in place.  Sewerage & water pipes can be replaced with pipes that can’t be invaded by tree roots or re-routed & be done with the problem forever. In Canada, they use a system that allows pipes to be replaced without digging, disturbing or damaging tree roots. They use a water flushing vacuum system to remove the soil from around the roots, pipes or wires, then install the new pipes & put the soil back in.

You don’t even need to put in concrete foundations near a tree when you are building anymore.  Again in Canada, they insert giant steel screw piles into the ground that are just as stable as concrete foundations & require no digging.

There is also a high-density plastic grid system that I have seen used in Sydney.  Once laid over the ground the grid disperses the weight of vehicles over a larger area. The grid also prevents soil compaction, which can damage roots.  Best of all, the grid allows rainwater to permeate the soil, reducing the need for irrigation & improves storm-water management. Ground cover or other plants can be grown in the spaces within the grid.

The grid also prevents soil erosion. I can see these grids used to support riverbanks & to create cement-free car parks. They could also be used to channel water into the ground near a street tree rather than be wasted by pouring down drains.  There is no reason why a section of the gutter cannot be a grid.

There is also porous concrete used across City of Sydney & North Sydney Councils.  Porous concrete provides a seamless surface allowing people to walk across it, but still captures any rainwater that falls on it, watering the tree.

There are quite a number of beautiful Figs in Marrickville LGA & many of them are planted near buildings. Unfortunately many of these trees live in less than perfect conditions with cement & bitumen almost to the base of their trunk. Many have cars & trucks parked right next to them. As we have seen, it is only a matter of time before branches get gouged or broken off by trucks.

Canary Island Palms line Graham Avenue Marrickville. I hope these trees are heritage protected.

The only reason why money isn’t spent on protecting trees before problems start is that trees are not held in high importance or the Council is so strapped for money that understandably, urban forest issues get moved down the list of priorities.

Many Councils do hold their trees in high esteem & look after them. They use floating footpaths & permeable rubber surfaces or permeable ‘solid’ surfaces. They put garden beds around trees to prevent or limit the amount of vehicles that can park under them. They put ‘no parking’ signs for vehicles over a certain size & weight & they do other things like prune dead branches & normal die back. They probably feed them occasionally as well.

I would do all of the above & if property damage occurred with people saying get rid of the tree/s, I would think it is the community’s & Council’s best interest to fix the damage (within reason, once proof & access has been given to Council) & put things in place to ensure the problem won’t repeat itself.  Too many people & future generations miss out for cracks to walls & pipes, both which are easily fixed without costing as high as the value of losing a tree.

Trees are the only things Councils own that increase in value each year.

Prepare for big changes in Marrickville because this is just the start of high-rise

1.    The Environment Department has done aerial seeding of 1 million trees across nearly 6,000 hectares of exposed lakebeds in South Australia to ease soil acidification. “It is hoped the plants will stop a spread of toxic dust & add vital organic material to the soil, in a region which faced prolonged drought.” http://www.abc.net.au/news/stories/2010/06/28/2938871.htm

2.   Clarence Valley Council has done something amazing for the environment. Funded by the Department of Environment Climate Change & Water, they planted 300 rainforest trees for flying-fox habitat over an area of about 3,400 square metres in McLean to manage the bat population. Terrific & compassionate program, far better than the usual to just chuck the bats out or simply cut down the trees. Loud applause. http://www.environment.nsw.gov.au/media/DecMedia10061801.htm

3.   Yesterday I posted about Goondiwindi Regional Council chopping down Fig trees despite community opposition. Now the Council is going to spend $96,000 on floating footpaths made out of more than 80,000 recycled milk bottle caps. Using this type of footpath means they won’t have to cut the roots of trees or even worse, remove healthy trees because of roots affecting footpaths.  They said they were prepared to send this kind of money because they, “understand how important these trees are to residents.” http://www.goondiwindiargus.com.au/news/local/news/general/tree-choppers-are-really-tree-huggers/1872430.aspx

4.   Nine 150-year-old trees in Burdekin Park near Singleton are to be chopped down because bats classified as threatened species have destroyed them. Singleton Council has arranged to have a qualified bat handler assess & stay with the bats during the nights when their homes are being removed. http://www.theherald.com.au/news/local/news/general/singleton-trees-cut-but-bats-guarded/1873363.aspx

5.   In NSW a research team from the science & research division of Industry & Investment NSW has managed to record thousands of calls of the Microbat for the first time, making it easier for scientists to identify & protect their habitats. Microbats consume up to 1.5 times their own body weight in one night & are a vital part of our ecosystem. They, like many other of our wildlife are threatened due to loss of habitat because of development. http://www.smh.com.au/environment/conservation/bat-man-bugs-hungry-wee-beasties-to-save-them-20100626-zavf.html

6.   Bats are thought of very differently in Italy where people have purchased more than 12,000 bat boxes at £25 each since April 2010 to combat the tiger mosquito that has infected hundreds with Chikungunya Fever. Each bat eats around 10,000 insects a night so they are a non-chemical organic approach to mosquito control. Everyone wins, except the mosquito. http://www.independent.co.uk/news/world/europe/italians-recruit-bats-to-take-sting-out-of-summer-2006124.html

7.   Hornsby has a new community action group called Stop 20 who are opposed to Hornsby Council’s draft housing strategy, which includes 20-storey housing developments. http://cumberland-courier.whereilive.com.au/news/story/stakes-are-high-for-new-action-group-stop-20/

8.    On 28 June at the Commonwealth Forestry Conference in Edinburgh UK, the Commonwealth Secretary-General said, “We need to show, financially, that trees are worth more alive than dead. Forests, we know, represent almost three-quarters of the world’s terrestrial carbon. Cut them down, & they are responsible for almost a quarter of man-made CO2 emissions. Tackle deforestation, & we go a long way towards tacking climate change.” He also said in 20 years time 80% of the forests that covered the earth in 1947 will be gone.   As well as the loss of thousands of species, this will also “accelerate the climate changes that destroy our other natural environments, our glaciers, grassland & coral reefs.” http://www.thecommonwealth.org/news/34580/34581/225538/280610forests.htm

9.   Chen Maoguo, a very brave man sat up in a Euclyptus tree in China for more than 3 months to protest the planned demolition of his home for the building of a shopping mall.  Mr Chen is being tried for disturbing public order. I hope he doesn’t get a gaol sentence. http://www.dailytelegraph.com.au/news/breaking-news/bird-man-faces-charges-in-china-for-sitting-in-a-tree/story-e6freuyi-1225885245007?from=public_rss

10.    A number of communities in the state of Massachusetts USA have lost hundreds of thousands of dollars of street trees that have died as a result of underground gas leaks in degrading pipes in the National Grid. http://www.boston.com/yourtown/news/quincy/2010/06/gas_leaks_are_killing_trees_in.html

11.   The Migratory Bird Conservation Commission in the US has approved $35.7 million for 6 million acres of wetlands & bird refuges across the US &  Canada. http://www.humanitariannews.org/20100617/wetlands-migratory-birds-get-357-conservation-grant-government

12.   Pavlovsk experimental station Russia, one of the world’s oldest seed banks is soon to be demolished to make way for housing.  The seed bank holds more than 4000 varieties of fruits & berries from which most modern commercially grown varieties are derived. http://www.newscientist.com/article/mg20627663.500-vital-fruit-and-berry-collection-set-for-destruction.html

13.   8 turbines are to be put under the bridges crossing the river Seine in Paris to raise energy from the rivers currents. There is already an underwater turbine under the Golden Gate Bridge in San Francisco. This article also mentions that Paris has a free bicycle scheme. http://www.guardian.co.uk/world/2010/jun/28/paris-power-turbines-seine

14.   Chicago is going to do a census on its trees after doing one 17 years ago.  http://ht.ly/21Ht3

Watching the documentary Greatest Cities of the World on Tuesday night I learnt the finest honey in France is from a beehive on the roof of the Paris Opera House.  Not illegal, just using available good quality space.

lovely old tree in Dulwich Hill
