Restoring a rainforest

At Billys Creek farm, (Lillys @ Billys) we are starting to restore the rainforest. Works include a little bush regeneration of the riparian corridor, and planting trees. Long term this will be an educational area. Some trees that have long been removed, like Red Cedars and Rose Wood are now being replanted. Long grass is wipersnipped, rainforest species are planted in larger 140mm pots and they are staked with pink stakes, so we can find and maintain them. A full selection of species has been planted and labelled for educational purposes in a corridor.

Planting, weeding and a suprise spotting a Southern Headed Dragon. Just imagine when the dinasaurs roamed in this Gondwana Forest.

Our entry to the rainforest, wait for the bird sounds

A walk in an ancient Gondwana forest

We discuss how rainforests control fires and local Koala habitat near an old growth Warm Temperate Rainforest in the mountains behind Dorrigo NSW. These are wet meisic forests, with unique flora and fauna. There is so much to learn about the benefits they provide.

On a walk around ancient trees we looked up to see bright green light eminating from birds nest ferns high in the canopy. Majestic trees tower to the sky. We are careful where we step as there are tiny cotyledons of trees popping up, sometimes on mass. Its like being a kid in a lolly shop, at every turn there is another surprise, a moss covered tree, a sound, a feeling of being of the earth. When in this space, time is immaterial. I feel the health benefits as my feet sink in spongy leaf litter over deep moist soil. Its dark and still, your are enclosed in nature. Poderoos and Bandicoots have been nusling into the ground digging profusely for their favourite truffles. Standing still we hear enchanting bird sounds, not found on our surrounding farm paddocks. This forest is almost identical to the forest that existed 180 million years ago when 3 continents called Gondwana were joined. Then, dinausaurs would eat leaves and fruit, others would hunt down slower species crashing through what is a now a very tranquil place. There were larger trees back then, you can still see where the loggers toiled to get them out . A few large stumps are spotted throughout the forest, some 3 metres in diameter. On deeper inspection there is a miriad of life in the soil, in the trees and in the water. Only 200 years ago Gondwana wet forest covered a lenght of 2000km on the Australian east coast, only 1% of it now remains.

As we walked every new bird song initiated an perplexed look at each other as we stand frozen, not to make a sound ourselves. After the bird songs stop we confirmed the sounds on our Bird App. Paradise Rifle Birds, White Throated Tree Creepers, Pale Yellow Robins, are all birds that stay in the deep forest. The Tree Creepers with their long beaks need rough barked trees, the high surface area provides a sufficient food source. They creep along tree trunks and branches pecking continuously to catch their daily meal. Without these rough barked giant trees, the birds would not be here. Paradise Rifle birds stay high in the canopy on a horizontal branch, the males exibiting elaborate dancing rituals to impress mates. As we ambled, we could hear two Rifle birds communicating from each side of the forest with their raucus screaming call. Koala scratches were spotted on their favorite food trees on the edge of the rainforest. We could see where they energetically pulled their chubby bodies up the line of least resistance on a huge Tallowood. Some of the many tree species present in the forest were Red Ash, Pink Cherry, Mountain Walnut, Rose Wood and the Ancient Dorrigo Waratah. Tree Waratahs are from the Proteaceae family an ancient lineage with a fine mesh of roots. They require a mychorrizal fungi on their roots to prosper. Tree species that seed in the rainforests, are often dispersed by birds who eat their fruits. A complex ecology, where the many species allow it all to function. A big carbon sink which sheds pure water.

Pictures above: Tree creeper, Giant Barred Frog, Koala markings, Paradise Rifle Bird

At night a range of frogs and nocturnal snakes come alive, one food for the other. In this forest is the Giant Barred Frog and Stuttering frogs, both endangered. As we walked we continued to hear the gurgling of our meandering creek as it flows over rocks and into large pools. I often sight a pair of Platypus’s frolicking in the water or scatching themselves on fallen logs. The water apearing from nowhere, is feed by the surrounding forests and appears as a spring in this rainforest.

Rainforest forms a barrier to fires by the fact that it is so wet. Leaves on the ground, although thick form a mass of moist debri. It is home to a range of invertebrates recycling carbon. We discuss how the the calm feeling within, guided us to the best path, avoiding vines and moss covered logs. Interestingly where the fires did not damage this forest, there are few flammable species. Leaves of many species are thick and fleshy.

Other species of interest is a small plant Ziera smithii which grows in forest clearings, they have medicinal properties. These and other plants spur Dorothy and I to explore on the commercial part of our farm. I know that walking in this forest is good for you physically. There is a meditative aspect to it too. Walking in forests is carried out in a number of countries for medical reasons, they call it forest bathing. The native Gardenia, Atractocarpus benthamianus attracts bees with its smell, and me!. The water from our creeks, is clean and drinkable, eventually it feeds the cities of Grafton and Coffs Harbour. Keeping it clean and flowing, is essential for people as well as the fauna and flora here. All part of our natural capital.

In 2019 the local area was subject to extremely dangerous fires, 60 houses were destroyed just a little North of our property. Fires are a common phenomina in Australia, but never in rainforests. They are becoming more prevalent due to climate change, scientists say. Fires do more than harm trees, thick ash pollutes water supplies, smoke damages our lungs. This area and the whole of NSW was covered in harmful smoke for months in 2019.

There is extensive clear felling of forests taking place just to the north of us, by the Forestry Corporation of NSW. Incidently this land was Koala habitat. The quick growing plants that spring up after clear felling, just add extra fuel to burn the rainforest and our homes. Much habitat in the forms of hollow nesting logs are lost with this logging method. Although there are rules on what can and cant be logged, I have been told these are not always followed.

On our property, some fires, did creep into the rainforest and did quite a bit of damage to two hectares. Where the fires came through in 2019, large rainforest trees were killed, they do not have the fireproof bark protections or growth habit of drier species like Eucalypts or Acacias. Where the fires were intense surrounding the rainforest, the forest floor is strewed with blackened fallen logs. Where there is light new flammable seedlings are now appearing with an abundance. On a windy night I can hear still hear dead trees from 2019 crash thunderingly in the forest from our home a 1000 metres away.

Photos above: Tick bush, Acacia binervata and A. melanoxylon all are highly flammable. This is scary in terms of damage to the rainforest that will occur in the next and inevitable fire.

The locals tell me about the tragic events after the long drought ending in 2019. People tried to save property by lighting defence lines only to find scorching winds blow them towards houses. There was no water left in the creeks and they used harvestors to open up forest tracks as all the bulldozers were off fighting fires elsewhere. There is a great deal of publicity when the fires are burning, and the firebrigades are risking their lives. But proactive actions in better times are neeeded too. They say that if you burn it, it will burn harder next time. Careful management of the land is needed. Timber and logging can be a sustainable business if done selectively allowing for a diverse habitat for plants and animals. Old growth forest like ours and its scarcity is critical to maintain. We need to protest against the poor logging practices by our government and its contractors.

Rainforests form a protective moist shield as is evident on our farm. For the sake of the country, rainforests need to be saved. Seeds are scarce, small trees or seedlings in the rainforest may be the only stock available for the future. They wait in readiness for a break in the upper canopy, for the light needed for grow. Species like Rosewood can stay in a state of suspended growth or as seed in the ground for 10 years, waiting for an opportunity to grow. It is critical to protect this process as early loggers removed many of these iconic tree species.

Today with our new appreciation, we eagerly pulled out flammable seedlings. Our job is to look after the rainforest, and ensure fires do not enter. We will extend rainforest plantings and provide an access track to help fight fire in the future. I have planted a number of provenance species and labelled them on a walk towards the forest to educate people on guided tours of our farm. Our guests find the farm facinating, enjoying the range of birds and hopng to spot the ellusive platypus. As darkness falls the joy of watching the dancing flames around a campfire, our weary bodies sink into a darkening sky full of stars and the occasional comet.

Biodiversity improving humans health, and some new plants for green roofs.

Dorothy and I had the pleasure to accompany Dr Oliver Griffith (Oli) on an ecological scouting mission this weekend. We were assisting Oli by providing transport for his research work and company. On a winters day our destination was Kanangra Boyd National Park NSW. In this location I was able to find some interesting plant species too.

Southern Grass Skink - Pseudemoia entrecasteauxii

Southern Grass Skink - Pseudemoia entrecasteauxii

The purpose of the trip was to see if the habitat for a unusual and pretty Skink (Pseudemoia entrecasteauxii) was still there after the mega fires we had this summer. The fires burnt 444,000 Hectares over Christmas 2019 with flames 200ft high.

The area and fire

Back to my story why we depend on biodiversity. During my Uni days we learnt how lungs developed from the fish swim bladder, these bladders evolved to give fish the ability to move up and down the water column. Oli is looking more closely as how our separate organs evolved, his speciality is the placenta. Whatever you think of humans value on earth it is hard not to realise that our evolution in terms of behaviour and physicality has led to substantial endeavours as a species. The broad term evolution must be thought of in its distinct parts. Every part of us has evolved over time. The pretty Skink at Kanangra has evolved from its closest relatives an ability to give live birth. Its relatives lay eggs like a lot of reptiles. This ability to give live birth has evolved in a number of species. Humans are one such species although in us it evolved in apes. It is one of the reasons we are successful and leads to care and nurturing and perhaps the development of our inquiring minds. If you are interested in Oli’s work you can read more at https://findanexpert.unimelb.edu.au/profile/824983-oliver-griffith or https://www.oligriffith.com/

In Australia this unique species of Skink may well be endangered due to the recent fires. It is pivotal in Oli’s research. Research that has led to a better understanding of fertilisation, cancer and as yet unknown developments in health medicine. There are thousands of advances we have made from understanding unique features developed through evolution over the past 3 billion years on earth. Here is a guy (Oli) who has completed 10 years at Sydney University, was hire by Yale University for 3yrs where he undertook extensive research and now is Lecturer of Evolutionary Genomics at Macquarie University. Oli says we have identified around 20% of species on the earth. He goes on to quote another scientist that of those 20% , we only know about their basic features and where they were found. We know less than 1% of their physiology or function. NOW THATS WHY WE NEED THEM FOR FUTURE OURS AND THEIR BENEFIT.

The habitat

On examination of the National Park, we discovered major damage by the fire. The Skink likes to habit large tufts of Lomandra longifolia. Complex habitat is also required for the Skink and that includes leaves, logs and branches. In the areas Oli had previously found the Skink, they had all been burnt to bare earth. Temperatures burnt many trees down to 2 metres underground the heat must have been intense. Close by, were large mountain bogs or perched water tables. Even these had their foliage burnt off, although the peat below remains moist. Further away we did find a few areas where the Lomandra’s had survived and some complex habitat was spared. As it was winter the lizards would be hibernating but we have hope that this unique species will still be in some places and re-establish over time. This way the research can continue. This Skink species is hightly adapted to cold climates, as the following plants. Who knows how they will be effected by climate change.

My other interest on these trips is to study plants growing in harsh environments on shallow soils. I share some with you in pictures. You will see the area is badly burnt. Many Australian plant species cope and are returning. The area is normally impenetrable, but now we can freely walk through the ash and blackened trees. Wombats survived, their fresh diggings and square poo gives them away.

The plants

Yes, Oli is our son.

Part 4 The development of a viable utopia

Please read part 4 for a summary of where we are up to.

Kabul is a perfect and peaceful place to communicate my findings with the known universe. For me it is as if Kabul is the centre of knowledge. Our university consistently makes great discoveries in many fields. The Kabul climate is extremely hot in summer and very cold in winter. This variation in climate seems to stimulate a vast group of students and professionals to attend Kabul University.  Our cities compare in technology with the best cities in the world. Buildings are sustainable and poverty is a thing of the past.

Babur gardens have a long history in Kabul

I have a small but comfortable flat in Kabul city, a short walk from the University. All around me are street food vendors. Long gone are the days when a female was fearful to be alone in a city at night. I feel safe walking through the streets 24 hours a day. In cool summer evenings the streets are vibrant until late at night. Nothing is better for me than meeting my intellectual friends in the cafes for a good debate. Even on my own, I like to watch others doing just the same. Actually on warm evenings people in large and intimate groups sit on the kerbsides and drink coffee and tea. The evenings in summer is a time to relax amongst friends in open space. When we have a little more time we like to wander and relax in the Gardens of Babur. These ancient gardens have interesting horticulture and a mecca for tourists.

The countryside outside the city of Kabul is inspiring to visit and only minutes away. Huge mountains surround the city and they are often snow-capped. On the valley floors sustainable farming practices flourish, and produce the best tasting fruit and vegetables. Water of course is a vital and a well-managed resource for horticultural crops. Our best food comes from farms which have grown produce in the same fashion for thousands of years. Many farms are small and first feed a small population that live within a few kilometres of the fields. This saves both water and transportation energy. Surplus produce is sent to city markets in Kabul. Most farms are a little business that have been held in the same family for generations. The fields are kept in good condition with added manure from the farmers livestock. The farmers are extremely skilled in horticultural practices and know just when to plant their crops and how to irrigate to maximise productivity.

As a child on the farm I watched both hard work and laughter. I watched the men and women toil but use great skill to produce abundant food. On a recent trip to my old home, I was surprised by Abdur and my old classmates. They arrived in a small bus with banners wishing me well Down-Under. After a briefing, we naturally moved to a banquet made of traditional foods lamb, rice, vegetables, yogurt, mint, lemon and garlic, followed by fruits including my favourite the pomegranate. It was such a natural thing for me to mix with my friends, food, and their utmost respect for me and my studies. I thought, how much I may miss this in Australia.

In Kabul CBD we have some great high tech structures amongst our heritage buildings. As with all major cities now, green infrastructure is the go. Low carbon construction and energy efficiency has been achieved. Plus the vegetation on the roofs and walls of many buildings provides beauty to the city. Many buildings have indoor and outdoor fruit and vegetable gardens to supply food to the residents and workers. All types of birds and nature is brought in by the greenery. It somewhat reminds me of my childhood in the forest. This nature experience provides an ideal place for thought provoking research.

future schools 2.jpg

Some preliminary research that was distasteful had to be done. I have to look at the chaos that had taken place in the lead up, in the 16th and 17th century. I needed to fully understand it, so that I can spot changes in our behaviour. It was a time of chaos and war.

If you don’t want to hear about horror.... don’t read this next section, skip and wait for Part 5.

People from the 17th century in Europe of whom this story is partially about had witnessed the destructive power of wars first hand and had an acute knowledge of history. Most recently and closest to them were the Napoleonic wars and how they spread from France to Egypt and the Americas. Apart from death and long term physical injuries from war many people suffer acute physiological trauma.  They suffer due to what they have witness or been engaged in. Governments find young soldiers easy to manipulate with their propaganda.

Soldiers forgetting their actions often manifests itself into post-traumatic stress syndrome or PTSD. This illness often goes unnoticed as they attempt to live a normal life with a partner and have a family. Many just become hermits unable to face relationships with anyone. Having poor communication skills and a partner that has no idea what you have experienced is a poor recipe for a happy relationship. It can be even worse if the people affected by war are in establish relationships. A soldier’s behaviour is more likely to affect other members of their family. A lack of communication skill often leads to violence aimed at their offspring. When in young experience violence from their parent in the safety of their home they too develop physiological illnesses. The war experience has now spread to two generations. It is said that this can often continue and thus the effects of war continue often lasting 3 generations or 60 years after the actual war ended.

War is a result of greed or poor negotiation by leaders of countries. War is the worst form of theft. Even Aeschylus from ancient Greece taught us about war when he said “In war, truth is the first casualty”.

Apart from war the people of the world in the 1700’s were all too familiar with violent acts sprung upon them by their own rulers. Often ethnic groups were targeted or the poor just to clean up poorly managed communities. There was a lack of compassion by the wealthy for the working classes and a great uneven distribution of wealth. This led in part to great revolutions as happened in France in 1791. Slavery too was prevalent also at this time. Various groups of opposition were trying to wipe out this repressive scourge.

A period called the Enlightenment formed around this period. In this time people could freely speak their mind and expose corruption, something the ruling class up to then did not tolerate. Previously free speech was viewed as treason. I’m sorry to harp on the actions of humans, but it plays an important element of why I believe the world changed with the advent of reason and by those remarkable events that followed in Australia.

Part 2 The development of a viable utopia

I had learnt early in my degree that the United Nations was able to keep skirmishes at a minimum in the 20th century. They used a technique of educating called Alternative to violence program. This program provide each member a way of being heard, the skill of listening has wonderful results. The United Nations world ecological sustainable development budget was only 10% of the 10 trillion dollars we might have spent on conflicts, a substantial saving. The budget provided considerable funds for education and action. Great leaps were made in water, air and biodiversity habitat. Development projects went through a framework that ensured our lands, rivers and the ocean were well protected. I knew I would learn much more about this in Australia. Sustainable management practices is an area where experts from Australia contributed greatly to the world order. I will continue to tell you about Australia’s expertise later in my story.  Abdur my mentor, increased my enthusiasm and analysis by his specific request for my research. One of my tasks was to study historic communication records. Particularly from early in the industrial revolution. Abdur asked me to search for the early documents written when the 1st fleet first settled in Sydney Harbour. I wondered what records existed from this time, and where I might find them.

Abdur was interested in what happened to the psyche of people that made them avoid the catastrophe of wars. He wanted me to analyse in detail the physiological changes that he said took place in early Sydney Town. Abdur observed that people seemed to wake up from their customary greed solutions based at this time. He had an hypothesis that certain events in Australia had led to significant changes in human behaviour, even an evolution in humans thinking. My behaviour, I felt was attributed to a childhood in nature. Later the study of ecology at school gave me an escape from my personal struggles. I developed a deep passion for all books about ecosystems and plant relationships. I would stroll through forests with a keen eye on flora and fauna, here I felt serenity.

As a smaller child the fascination of insects, toadstools, in the leaf litter around trees kept me busy for hours. There was also the bigger animals I saw occasionally in the distance like Deer. Once when I was 3 years old my father took me in the mountains very early in the morning with a pop gun. I remember thinking I am a hunter, and he went along with the game. As we crept up the mountain path we saw up on a rock a snow leopard, he was looking at us intensely. Its times like these that are locked in our minds. I always loved my father for experiencing these things together. Afghanistan is such a safe place for children to roam. I wonder is this a why I had a less greed based focus?

One day Abdur called me in to his messy office. Here he had books from floor to ceiling on every wall. On the floor was stacks of books and student assignments. He asked me to sit in an old but comfortable chair opposite him at his messy table. I did notice is that despite the mess there was no dust, he was obviously moving all those documents, whilst feverously doing his work. He looked me in the eye with deep penetration. I knew something was up and I started to get a little nervous. He said “Sharbat, I have found an important task for you. I need your full efforts to make a discovery, it will require a very different effort from what you have been doing in Kabul. Before telling you what it is, will you commit to helping me?” Weather it was foolishness or my adventurous nature I instinctively said Yes, without knowing any more. He exclaimed “good! and told me I needed to spend some time on the other side of the world, to Australia”. Now that’s quite a change for me and I realised then that I was about to experience a lot of different emotions. On the one hand I was excited, another reaction was why?, and what for?, this gave me a confused feeling. He then said ,”I have another meeting just now, we will have to talk about this later”. As Abdur was talking to me I could feel my emotions swell, I could feel my muscles particularly in my face moving. I knew he noticed all these expressions and would only wish me the best. I sat up and walked to the door in a state of confusion. I remembered Bilbo Baggins saying “It's a dangerous business, Frodo, going out of your door”.

For a few weeks I had difficulty sleeping, not that I felt bad, I had a positive stress. It was going to be an exhilarating experience and I anticipate an huge expansion of my knowledge. Afghanistan and Australia are on opposite sides of the world. My childhood memories of falling out of a tree kept me thinking “here we go again”. I think fear and happiness are both sides of the same coin. It’s like melancholy something else I experience from, time to time. It and depression are like dark chocolate, addictive yet demoralising. Melancholy can give you acute life awareness, I have developed a healthy outlook to these feelings. I put these emotions of mine down to what confronted me by watching my parents disjointed relationship. Now I was confronted with a decision. Do I start a task so big as to change my life and leave my comfortable home town of Kabul or do I take the easy road and stay. In the end it was my mischievous nature that made me do the risky things. I again needed life’s intensity, perhaps suffering. Australia here I come, it was the lure of dark chocolate.

Part 1 - The development of a viable utopia

I write this anthropological study of how society has evolved into our current state of harmony. My name is Sharbat Gula, I am an aspiring female studying in the university of Kabul. I am undertaking PHD research in Socio-biology. I originated in a small farming town outside of Kabul. As a child I helped my parents and one of my brothers, Jalup, grow crops. Mostly, I just ate fruit from the gardens and played with my friends. Jalup and I also explored the forests at the base of the mountains surrounding my home. Here we would pick mushrooms and spy on native animals on the mountain sides. We both had wild imaginations of living up there near the snow and in caves. I also used to get up to a fair bit of trouble and generally learnt my lessons the hard way. Like the time I learned about gravity by falling out of a large Pistachio tree. Family life for me was confusing as I was considerably younger than my siblings, they had all seemed to have gone their own ways and that included my parents. I had to be resourceful but needed to learn the lessons of the world by myself. Materials needed to support my education were always provided by my parents.  But these two humans I was to learn from most about relationships seldom saw eye to eye. A storm of emotions could be wiped up between my parents and I learnt that this behaviour was normal. Confusion about human emotions probably led to my lack of awareness of right and wrong. My enthusiasm for life however was never dampened and I would get into all manner of mischief. Never being without enthusiasm and later obtaining good university marks brought the attention of my lecturers and interesting times. I tramped the country looking for endangered plants to propagate. I spent all holidays locked in a room developing new software. Other times I sped up dirt tracks on my motorbike as yet more adventurous behaviour. People used to asked why do you do this or that. I think it was my addictive personality and a passion for the new.  When I first started university I barely knew why I was embarking on this road, slowly my interests grew. A grit and determination got me through my degree and subsequent PHD. What surprised me most about university is its practical application to real world issues.

Humans are obviously part of the worlds biology and have evolved from the traits of animals. To me it was fascinating to investigate how humans became cooperative and rid themselves of aggressive behaviour.  Had it not been for certain decisions made early in the industrial revolution we could have become a very different society. I would hate to think what our current advanced technology could have led us had we not kerbed aggressive self-interested behaviour.  An understanding of our peculiarities as a species drove me to more knowledge. This is the story of what changed human behaviour from self-interest to a more sustainable community.

Early in my degree my professor Abdur Rahman had been engaged by the United Nations. His role was an extensive statistical analysis of economic costs of human behaviour. More specifically he was looking at the costs of negative behaviour resulting from conflicts.  His study concluded that should humans have continued on their destructive path from the middle ages a number of wars would have ensued at considerable cost to innovation, ecosystems, productivity and human life itself. Abdur was a small man who had a poor grasp of the English language. He was highly intellectual and I can only hazard a guess of his IQ, but it would be very high. As Pesian was my first language I understood Abdur very well.  Foreign students had to listen hard to his broken English and probably did not grasp his intellect and inquiring mind. For me this was wonderful, here I could use his knowledge exclusively. Abdur pushed me to think like my father and I love him for that.  Based on Abdur’s research the statistics indicated there was a 75% probability of 3 world wars in the 20th century. There was also a 90% probability of 100 smaller wars in and between countries. He ascertained that these wars would cost in excess of 10 trillion dollars ($10 000 000 000 000) in today’s value.

For me Abdur’s interest in this subject had an added dimension. I was brought up by two parents that could barely agree on anything. As a small child it looked a lot like conflict in my own house. Both my parents encouraged me to question my assumptions. I remember my father pushing me to think what is the difference of being alive or dead. What is the difference, what element exists in a living thing? At a young age I struggled answering this interesting question. I also wondered if there was a better way than conflict. I found my time in the forest gave me a freedom I craved. In relationships I asked myself was there a conflict between relationships and freedom? These questions and more drove my thirst for knowledge.

Preamble - The development of a viable utopia

My sons tell me that every good story has a conflict and a resolution. Well this story is much the same but the conflict I can quickly tell you now, and it could be no more real than our current world situation. Consider waring countries, world poverty, species extinction rates, climate change and desertification, just a few issues we currently face. These represent a conflict, just as it is. My story goes on to describe a fictitious solution and historical events that avoided the aforesaid problems and how the world found harmony. I am avoiding politics and am concentrating on a utopian outcome. It is hoped that the reader may learn from the solutions provided and assist in repairing our past sins. I will talk less about the problems from here on, just that you need to remember this conflict, if I am to meet my sons requirement of a good story. By the way my avatar (Shabat Gula) an Afghani student will be writing the story from here on. She has a passion for learning and life and wants to involve you in it. Set mostly in Australia it involves a relationship between new settlers from England and Europe and the Aboriginal people that inhabited this land for 60,000 years prior.

It is my first attempt at writing such a story and I am open to suggestion. I will release the chapters over time at https://evolvement.squarespace.com/biodiversity/2020/1/25/preamble-the-development-of-a-viable-utopia . Comments received or encouragement may alter future chapters.

Australian native biodiversity for a Green Roof is possible

Over the past 10 years I have been studying Coastal Sandstone Plateau Rock Plate Heath for its resilience. I am particularly interested in the way plants grow on shallow soils around Sydney in this vegetation type. There is a wide variety of diversity in both flora an fauna in this heath. There are some special plant adaptions and symbiotic relationships that make these plants thrive in harsh conditions. Wherever plants grow there is a rich abundance of lichens, mosses and insects above the ground. The symbiotic relationships ensure moisture is retained and nutrients provided to sustain a growth. Below the ground fungal mycorrhizal associations are related to nutrient exchange with fungus benefiting from sugars created by plants photosynthesis. The plants benefit from the nutrients available from the huge surface area that fungal hyphae provide. When plants are under extreme stress, after a few months without rain some take a deep red colour in their foliage. This could be a defence mechanism which is often associated in red leaves and toxic compounds.  Apart from field research my experiments included growing these plants in green roof modules over a 3 year period.  I observed how species persist and thrive. On the ridge tops around Berowra plants will grow in 15mm of soil and are possibly decades old. I grew plants in trays 45mm deep with great results. Plants were grown from collected seed and cuttings, I included lichens and site soil to include fungus. It is my hope that emulating this vegetation type on our buildings that biodiversity, particularly birds will have their habitat enhanced in our urban environment.

There are many species, some include Leptospermum arachnoides, Calytrix tetragona, Gahnia aspera, Patersonia sericea and my favourite Micromyrtus blakelyi.

Ecosystem services

Abstract Green roofs have been heralded as a “sustainable building practice” in cities throughout the world as one response to mounting environmental stresses. A range of stressors plus erosion of aesthetics and human well being in urban areas have initiated policies and practices often with incentives to develop green infrastructure such as green roofs. They provide a suite of public and private benefits most of which map onto services generally provided by the ecosystem. Green roof development imbeds in environmental design processes and is constrained by both human and environmental factors. As relatively small, simple, anthropogenic ecosystems, green roofs relate to several existing conceptual and applied ecological ideas. Understanding and applying from ecology and ecosystem studies, ecological engineering, managed ecosystems, construction ecology, urban ecology, landscape ecology, restoration ecology, reconciliation ecology, soil ecology and community ecology show green roof ecosystems can be created to cycle energy and nutrients. Furthermore, green roofs can be constructed to model an ecosystem and may provide a setting for testing ecological concepts. This book takes an ecosystems approach to describing a large number of interactions on green roofs placing them in the total human ecosystem.

A Christmas trip to this distant location from my home lets me explore biodiversity and ecosystem services as provided by a seemingly arid landform of Australia.

Hundreds of kilometres of wheat and sheep farming country, recently harvested its the middle of summer here and 40+ degree celsius would not allow new growth.

Water courses are rare, particular with visible water. They provide key habitat for a large range of organisms and vital ecosystem services.

The wheat fields are all but harvested along the road to the city of Albury, there are hundreds of kilometres fields covering 10’s of thousands of hectares. This soil and land provides a huge part of the worlds food crop for bread production. China is a large customer of wheat and flour. A 15 metre wide harvester lets a farmer crop his 1000 hectare paddocks in quick time. He tills his field to reduced weeds for next years sowing and spreads lime to improve nutrient availability. Soil chemistry and microorganisms plays such an important part of a farmers yield per hectare. Soil depths are very shallow in this oldest of continents. Great care is required to manage our soils that thin crust that supports us all. Another strategy involves no till farming where microorganisms are less disturbed to do their magic, although this technique relies on increased herbicide use and whatever damage that does to biodiversity. Wheat crops in this area are not irrigated. A farmer needs to rely on rain, generally the area provides adequate falls but too much or too little at the wrong time spells disaster for the crop. A good farmer will provide flora and fauna corridors along his water courses.

Eucalyptus camaldulensis (River Red Gum) providing soil stabilisation services to a highly erodible landscape. E. camaldulensis is the most widely spread of our 500+ species of Australian Eucalypts. The key to erosion control is to always provide vegetative cover, this avoids  desertification.

Our shallow soils need care

A farmer ploughs twenty four seven, to provide his crop

He relies on climate, as do we

He feeds, we feed

Nature relies on us, we rely on nature

Careful thought is required

The native Blue Banded Bee Amegilla cingulata finds and exotic host in the Prickly Pear Opuntia stricta. This cactus once took over 40,000 square kilometres of Australia and was a catastrophic weed species. Luckily we engaged the biological services of Cactoblastis cactorum a butterfly and natural predator of Prickly Pear in its home of South America.  Cactoblastis has successfully controlled Prickly Pear and has made available tens of thousands of hectares of land for farming and biodiversity in Australia.

Water is a scarce commodity in western NSW, Australia. In agricultural areas of 500 – 700mm precipitation per year provides just enough for wheat and sheep farming, the most common practices. Canola an oil crop is also common.

Irrigation in this country is rare as creeks have a habit of drying up or flooding wildly. The Eucalyptus camaldulensis or River Red Gum is the dominant species along creek lines in western NSW. Evolution with natural selection has deemed that species find their niche. E. camaldulensis has the ability to withstand inundation in water courses unlike most other species. It’s timber is exceptionally hard (a terrific hot burning firewood). This gives the tree fantastic strength to withstand huge floods that periodically occur in Australian inland rivers. Its life cycle strategy is to drop millions of seeds per year, in a good season thousands of seedlings spring up in the wet mud. This tree species provides erosion control for our river systems, holding the creek banks from washing away. The tree itself provides excellent forage for bees and is host to many insect species. Old and narly branches are often hollowed out by termites and in turn provide safe nesting spots for a variety of birds and arboreal mammals. E. camaldulensis is a great provider of ecosystem services.

The 2013 flood of Urana creek. It flows 3 metres deep in this flat country and includes the town. The creek normally less than 3 metres wide swells to 6 kilometres in width and causes damage to towns. It is a natural occurrence and refills the inland lakes and seas. This is a 1:100 flood but it also occurred in 2012. The water results in millions of birds from all over the world flocking to our inland lakes and dining on abundant snails and fish.

The old railway bridge has trees growing through it and is a home for busy termites slowly turning it into compost. Now that cars are mass produced the railways have systematically been closed across NSW.

Nothing like watching the sunset in western NSW with a glass of wine. The red colour comes from the red dust further west in the Simpson Desert. Perhaps the story of my next blog.

A narly red gum shows its history

Floods and droughts of two hundred years

It drops its million seeds on wet mud banks

Dry leaves crunch underfoot

Ants of many types scurry in the hot sun

Creek banks are littered with branch habitat

Ducks, lizards and snakes enjoy

The muddy creek is full of carp

That’s western NSW
