Operation WOW...Watching Our Wildlife.

  Australian wildlife is becoming increasingly threatened due to loss of habitat, in fact this country has the highest extinction rate in the world! Most people are unaware of the amazing biodiversity that still exists-even in our suburbs, because many species are nocturnal and hard to observe.  Volunteers working to restore the Mermaid Pool (and its bushland surrounds) at Manly Vale in Sydney, have come up with a solution. They are producing nesting boxes with inbuilt cameras which will provide homes for wildlife (acting as surrogate tree hollows) and help provide the community with knowledge of their local species. 

 The nesting boxes will be located in areas of remnant bushland and some will be donated to nearby schools and businesses. Vision from inside the boxes will be transmitted live via the internet, using high tech telemetry, to provide an amazing educational and conservation tool.

  The impact will be to not only boost the breeding capability for possums, birds and micro bats but also give local residents and students an amazing insight into the wildlife that exists in their area. With more knowledge and empathy will, hopefully, come a desire to help protect wildlife and habitat. Biodiversity is disappearing around the globe and city dwellers often don't care because they have become estranged from the beauty of nature...here is a wonderful opportunity to get the urban population to reconnect! The local volunteer environment group (Save Manly Dam Catchment Committee) is overseeing this project and specialist nesting boxes are being made by retired volunteers at the "Men's Shed".   
 

  IT expert, Paul, is putting the technical aspects of the project together:- Based on the Raspberry Pi single-board-computer and the new Raspberry Pi micro camera, video and images will be shared via the world wide web. This will include real time views of the site and activities within the new nesting boxes. Nesting box in addition to a Raspberry Pi computer will be connected to a Mesh wireless network which connects to the internet. Additionally each box will be powered by a dry-cell battery that is charged via photo voltaic solar collectors. As many of the residents are nocturnal, they will illuminated their nesting boxes with infra Red which the cameras pick will up as monochrome images.

The nesting boxes will be delivered to the Mermaid Pool at 12 noon on June 22^nd 2013. Meet outside the UNSW Water Laboratory gates, Western corner of King St, Manly Vale.  Martyn Robinson from the Australian Museum will also be on hand to talk about local ecology.

Purple Menace Threatens Sydney.

  It’s been said that if our great city hadn’t been plonked on top of Farm Cove, the Sydney environs could have become Australia’s most spectacular National Park.  After all, our region contains over 2,000 native plant species, many more than in the entire U.K. So, here’s my exasperated gripe.  Since Cook first landed, we’ve been decimating the natural vegetation at warp speed. Walk down any suburban street and, chances are, you’ll find not one blade of remnant native grass. 

 To add insult to injury, people still plant harmful species such as Privet and Honeysuckle which escape from gardens and end up as bushland weeds.  Some deluded individuals even book into cruises to view the superficially attractive Jacarandas- a South American tree that is inexorably replacing the majestic Eucalypts and Angophoras around Sydney Harbour. Sadly, Jacarandas have become ubiquitous from Avalon to Zetland (and everywhere in between). In South Africa’s Pretoria, they’ve “wised up”. The “Jacaranda City” (featuring 55,000 such trees) has now classified these purple pests as an “invasive alien plant” due to its destructive root system and thirst for water. BBC clip on pesky Jacarandas

  You can tell I’m not a fan of Jacarandas but don’t get me started on Agapanthus...another introduced purple pollutant that seems to be the unimaginative “plant of choice” for McMansion owners everywhere. If the odd native seedling does appear in the occasional garden, chances are it is not an indigenous species but a hybridised product of the horticulture industry with a name such as “coconut ice” or “peaches and cream”. It’s these kinds of cultivars that provide an unnatural, but bountiful, food supply for Noisy Miners, identified as being the world’s most aggressive territorial bird. They’ve chased virtually every other avian species out of town!

 

 Tim Low in his book “Feral Future” argues that gardening has done more to harm Australia’s environment than mining. It has certainly contributed greatly to the introduction of the more than 2,700 weed species which have become established in Australia at a cost to the economy of over $3 billion p.a. In NSW weeds now make up a massive 21 per cent of the state’s total flora. 

 Even many local Councils are complicit in the “genocide” of native species, especially in our streetscapes. Why would they want to plant locally endemic Banksias when they could choose, hay fever inducing, London Plane Trees or American Liquidambars with invasive roots?  It doesn’t help when professional garden “experts” spruik foreign plants and chemical sprays for a dubious living. The original Sydney flora is diverse, beautiful, climatically hardy, needs no fertilizers or pesticides and supports our wildlife.  To plant these purple monstrosities is not just staggeringly boring, it’s, dare I say it? Un-Australian!

Tails of the Unexpected.

  I love Possums.  To me they represent an endearing resilience, a capacity to survive and adapt to the urbanisation of their habitat, against all odds.   
 

 In Sydney’s “Northern Beaches” area, we have three kinds of possum the “Common Brushtail”, which prefers to live in tree hollows formed by mature eucalypts, the smaller “Ringtail”, which generally builds its own nest (called a drey) out of twigs and leaves and the tiny endangered Eastern Pygmy Possum, listed as “vulnerable in NSW. These cute marsupials are vestiges of the incredible rich diversity of wildlife that was here prior to European colonisation. A fascinating glimpse of what once existed can be found in the Natural History Museum’s First Fleet Artwork Collection (Port Jackson Paintings, Flora and fauna).  Here we can see long lost inhabitants such as the Potoroo, Dingo, Yellow Bellied Glider, Marsupial Mice, Emu and the now totally extinct White Footed Tree Rat.

 Check out "The First Fleet Collection" on-line. 

 Even until fairly recently we still had small remnant populations of Platypus and Koalas on the Northern Beaches that eventually couldn’t cope with city living any longer and gradually disappeared.  Miraculously, Possums are still here, as a living reminder of our wilder past, despite being vilified by some. (Perhaps there’s a fur envy thing going on?) Possums, being nocturnal, are active at night, which accounts for their protruding eyes and shy disposition. The greatest enemies of the Possum are the cat and the car. So please, drive carefully and keep your moggie in at night. The average domestic cat kills 25 native animals a year and even if a captured possum seems unharmed, it is likely to die within 36 hours from shock or from toxins carried in the cat’s saliva.

If you find an injured possum please call Sydney Wildlife’s Rescue Hot line on 9413 4300 or WIRES on 1300 094 73    Sydney Wildlife website

To make a Possum feel really at home, why not locate a nesting box in your own backyard? Ask Sydney Wildlife or WIRES for details or Google “Possum Box Design” to find a plan and make your own.

Banksias are Better than Banksy.

  Australian tourists travel to the UK and beyond to admire the street art of enigmatic dauber “Banksy”.  Meanwhile, back home, some rather more wondrous creations go largely unnoticed.  I’m talking of a genus of around 72 native plant species called Banksias...named, ironically after another Englishman named “Banks”.  The person in question is Botanist Joseph Banks who sailed to these shores with Captain James Cook in 1770.   

  On the Northern Beaches of Sydney, we have seven locally occurring Banksias, all of which boast spectacular spiky flowers that morph into sculptural seed heads as they mature.  These showy flowers, ranging in colour from burnt orange to greenish yellow are fabulously rich in nectar which provides crucial food for honey eating birds, possums and bats as well as being highly attractive to bees and other insects.  In our area, a number of rare animals depend on Banksia nectar for food including the Eastern Pygmy Possum, the Brown Antechinus and the Sugar Glider.  Aboriginals used to suck the flower spikes to get a “nectar hit” or they soaked them in water to produce a sweet drink.  Many people are familiar with the “Banksia Men”, the villains of May Gibson’s children’s book “Snugglepot and Cuddlepie” which were modelled on the gnarly looking Banksia cones.

  Look in any local garden though and you’ll be hard pressed to see any Banksias.  They’ve largely been replaced by the ubiquitous imports from overseas, such as Jacarandas, Bird of Paradise plants, Tibouchinas or Agapanthus. If Banksias are around, they’re likely to be a hybrid, grown to be more robust or flamboyant by the Horticultural industry and not the “real deal”.  Indigenous Banksias can be seen in Bushland reserves such as North Head Sanctuary.  

                  

  If you’d like to plant your own, original endemic Banksia...go to a local native plant Nursery such as “Indigo” or “Harvest Seeds”.  You can purchase a tube stock seedling for less than $5. An inferior “Banksy” stencilled artwork, on the other hand, is likely to set you back hundreds of thousands of dollars. So choose the Aussie option. You’ll be laughing all the way to the Banksia.

Banksia Ericifolia (Lantern Banksia) is one of the most beautiful and abundant Banksias of our region. It is also important for birds such as “Honeyeaters”. Small birds may totally disappear from areas where it has been killed by fire

Keep Off The Grass!

  Lawns. Why would any sane "Aussie" ever want one?  The problem with lawns is that they attract public enemy numbers one and two; the lawn mower and the “whipper-snipper”. Now we all know that these pieces of objectionable machinery register high on everyone’s “Richter-scale” of irritability but why is it that the trigger for their drill-like, bleats, always seems to be me, settling down on a Saturday arvo, for a “quiet” uninterrupted read? There I am, embracing the silent sanctity of suburbia, when their acerbic drones are projected into the recesses of my brain like an electric eel. They encamp there until I’m blaspheming in the manner of a tourettes sufferer on steroids.
 

  What compounds my irritation is that this unctuous sound is an aural illustration of the ignorance, waste and futility that spawned it. It epitomises humanity’s descent into blind stupidity. Ninety nine times out of a hundred the “Whipper Snipper” is used to trim exotic grasses such a Buffalo, Couch and Kikuyu, which shouldn’t even be present in this fragile continent. Across Australia we’ve planted hundreds of thousands of lawns made out of foreign weed species that devour water and nutrients like they’ve gone out of fashion. That is idiocy.

  If my neighbours replaced their weedy lawns with native ground cover such as “Dichondra ” they would never have to whip, snip or mow again..ever! And the benefits don’t end with me being able to catch up on my “Sydney Morning Herald”. For a start their lawn will go from being a weed seed-bank to a beautiful indigenous “biosphere”. They would also save mega bucks by not needlessly investing in machinery, fuel, lawn-food and irrigation systems.  Petrol powered gardening equipment also accounts for around 5% of our air pollution. That’s a huge potential dent in greenhouse emissions just waiting to happen.  They would also economise massively on time...precious moments they could spend reading leading edge journalism or maybe just drinking, gambling and committing adultery. In addition they would be able to stay out of the sun and limit their exposure to damaging UV rays. Lives could be saved!

 When you add up the social, environmental, physical and financial equation centred on grass growth and grass grooming, it’s quite clear. We have been hoodwinked by the lawn and mowing sector at a level that would make Tobacco Industry lobbyists, turf-coloured with envy. 

Postscript:  I used to spend several futile hours a month mowing. In an enlightened moment I dug up the lawn and replaced it with the lawn substitute called “Dichonda Repens” more commonly known as “Kidney weed” (NB it is not a weed). This native ground-cover is available in tube stock pots from most nurseries and garden centres; it thrives best in semi shaded area.  Plant one clump, every square 100cm, in your newly-cleared patch. Water in well and weed regularly until established. You will soon have a gorgeous green carpet and never need to mow again!!
