The World of Fabulous Fungi

 

The focus of this article is on the beneficial Fungi found in the bushlands, forests and other landscapes.

Please remember that most Fungi can be toxic and some edible Fungi can have look-a likes, this requires caution and professional identification.

I see Fungi as the quiet achievers, the angels of the environment; going about, doing good, bringing about homeostasis into the earth.  Fungi possess such a uniqueness and status in the plant kingdom that should be applauded; actually they should receive a standing ovation!

At the base level of the food chain, they are vital for the health of the vegetation around them.  Without Fungi all life is seriously affected.

Some facts about Fungi

  1. They are important recyclers for our planet; important for all life at all levels.
  2. They have chitin in their cell walls rather than cellulose. Chitin is the substance insects and crustaceans use to make their exoskeleton.
  3. They do not have chlorophyll, so they cannot synthesis their own food from the sun’s energy. Fungi must rely on dead or living matter to survive.
  4. Fungi reproduce by spores and not seeds. On germinating, the spore gives rise to  cells called hyphae, when two hyphae unite, they start to grow and form the mycelium.  The mycelium consists of a mass of hyphae which weaves throughout the soil, feeding on waste and rotting matter within the soil.
  5. The mycelium gives rise to the fruiting body, which exposes and identifies the fungi present. For example mushrooms.
  6. All ecosystems depend on the effective workings of the beneficial Fungi.
  7. Fungi are the invisible framework of all ecosystems. They have the important role of breaking dead or living organic matter into safe, reusable nutrients; sterilising, fertilising and stabilising.  This makes them healers of the land.
  8. They support plants to thrive; by giving them increased drought intolerance and disease resistance.
  9. Fungi are placed in three categories, observed by their feeding habits:
  • Symbiosis
  • Saprophytism
  • Parasitism

Symbiosis

A good example of this is when we see the Fungi fruit linked to a living plant, such as a tree. In this symbiosis relationship, the fungi entwines it’s delicate network of the many hyphae’s around the plants roots, called mycorrhiza’s. This mycorrhizal connection is how they feed and support one another.   The Fungi feeds by extracting sugars and in return the Fungi supply the plant with nutrients, like phosphorous and water.   This is vital for both the plant and the Fungi’s survival and health.

Studies have shown that this symbiotic relationship has demonstrated that plants grow ten times healthier.

Saprophytism

These Fungi are mainly seen on things like rotting logs, branches, leaf litter including animal waste.  They play the role of primary decomposes of the various organic matter, including other waste; returning healthy nutrients back into the soil.

The Fungi can be seen on lawns, even away from other plants; feeding on waste and toxins, enriching and healing the soil.  They do this by spreading and radiating their long filamentous threads under the ground as they search for food.  This process enables the nearby plants to have access to the new enriched soil.

There are specially categorised Fungi in this group, ‘special agents’ that have the potential to breakdown numerous types of waste, like paper, plastic and even some petroleum products into safe, clean nutrient soil.  Wow!

Parasitism Fungi

They too are important in the maintenance of a healthy ecosystem.  They can be seen on sick or mature trees, eating into the heart wood and making tree hollows, by rotting that one section.  There would be a number of animals that would not be able to survive if these hollows were not made.

Lack of tree hollows is known to threaten a number of animal species survival rates, providing habitat for birds, possums, reptiles and other marsupials.

More interesting facts

At present there are over 249,000 species of Fungi in Australia.

To date there are approximately 70 bio-luminescent mushrooms on the Earth.

Despite their abundance and the huge importance they are to the planet and our very existence, Fungi are the most poorly studied organism.

Conclusion

Without Fungi all life would be seriously affected.  No Fungi, means there would be no plant life, no animal life, no oxygen, no food, no humans.

There is a small poem I saw once, I don’t know who wrote it, but it said;

‘The sky, a tree, and man will survive, if man understands the tree.’

This could be said about the Fungi.

In my book, ‘Emily’, I love to share about nature; I developed a fictional wildlife park, ‘Green Coastal Wildlife Park’, to teach people about the wonders of the environment, aboriginal culture, the Australian bush and beach, native plants and animals and the connection of each, and the characters of the book, as well.

Common Ghost Crab (Ocypode Cordimanus)

Australia has six known species, of Ghost crabs.

These little crabs are so good at camouflaging with the sand, thus their name, making it difficult to see them during the day, if for whatever reason, they happen to leave their burrow.

Ghost crabs are found on open sandy beaches, where they live in their immaculate burrows, (some known to be more than 4 feet), near the intertidal zone, in the dry sand. They are nocturnal and remain in their burrows to keep cool during the day and warm during the winter.

They can hold oxygen in their air sacs for about six weeks, handy when you hide and live under the sand.

During the night, Ghost crabs, fix and repair their burrow and feed on a variety of plant and animal debris that has been washed ashore.  These omnivores can even catch insects in mid-air; due to their 360 degree vision, that allows them to see in any direction.

Ghost crabs breathe through gills, which they keep moist at all times, by various methods, such as taking the moisture out of damp sand.

An interesting thing to do whilst relaxing on a quiet beach is to listen for the Ghost crabs, very distinct, bubbling sounds! They use their gill chambers to produce bubbly sounds.

The female Ghost crab incubates 1000’s of eggs inside her flap, and once matured, these eggs become marine larvae.  Mum releases her offspring into the sea, where they remain for about two months before returning back to the shore.

Did you know that the Ghost crab’s burrows are regarded as valuable ecological indicators for quickly assessing the impact of human disturbance on beach habitats?  And, they can travel across the sand up to 10 to 15km/hr.  Yes, they are fast movers, and that is why they are so hard to catch.  Isn’t it interesting that their generic name is ocypode, which in Greek means, fast -foot.

I remember one day while I was drying off after a swim, I decided to read and relax, I saw movement in the corner of my eye, and I spied a tiny Ghost crab, well camouflaged with the sand, right next to a small burrow. I went to pick it up and it quickly fled into its hole. I started digging but there was no way in this dry sand that I could find it.  The crab had dug down so deep; apparently, they can construct long pathed tunnels, to who knows where… hence another reason for the name, Ghost crab.

Of course, afterward I realised I should not have dug into his home, all that work would have been destroyed.  I vowed not to do that again.  We need to be sensitive to the ecosystem that in some environments are quite sensitive, the softer our footprint is, in the natural environment,  the better for us all; flora, fauna, marine life, and us humans.

Wattle Day in Australia

Wattle Day is celebrated on the first of September

Wattle trees are in abundance by the first day of spring, throughout Australia, in the bush, in gardens, on the side of the road.  The much loved Wattle tree has a time of splendour, showing off, its green and yellow or golden glow.  Wattle is the national floral emblem. It was eventually decided that we should have a ‘Wattle Day’, on the 1st September, the beginning of spring.

  • Through history’s pages Wattle has been held in high esteem, but for the first Australians, ‘the original land owners’, they considered a number of species of Wattle to be sacred. It was an important source of food, fuel and medicine.  They would grind the pods to make bread; known to consist of protein, complex carbohydrates and good fats; the bark was used for skin irritations, and the wood was used for making certain wood-crafts, like utensils and boomerangs.
  • On the 17th Anniversary of the discovery of Tasmania, Hobart celebrated on the 19th November, 1838, with sprigs of Silver Wattle blossoms.
  • Later in 1899 a ‘Wattle Club’, in Victoria, headed by Mr A J Campbell, a field naturalist; decided on their second year, to do a bush-walk on the first day of spring.
  • However, the first official ‘Wattle Day’ was celebrated in 1910 in Sydney, Brisbane, Melbourne and Adelaide and in 1915, the National Wattle Day League, was established to organise the official celebration.
  • Gaining more significance during WWI as Wattle sprigs and Wattle badges were sold to raise money for the war effort by organisations like the Red Cross. Wattle became a commemorative symbol to remember the men and women who fought for our freedom in war.
  • It is also, I believe a symbol of the Australian nation and its people; the Aussie way, character, new life, common purpose, mateship, hope, working together towards a better future, courage, generosity, good humour and prosperity.
  • Wattle is on the Australian Coat of Arms, as our National floral emblem, and it was planted along the Remembrance Drive, 320 kilometres of highway from Sydney to Canberra, as a memorial to the Australian war heroes.
  • We see the essence of Wattle in the green and gold of our Australian athletes, and sports teams in their green and gold uniforms, the ‘Boxing Kangaroo’ flag, and anytime when Aussie’s wear their green and gold to show support to fellow Australians.
  • Only a small percentage of the community these days celebrate Wattle Day, though it is coming into a revival again. It is not only a wonderful way to celebrate spring; it represents all that we hold most dear as Australians.  Why not wear a sprig of Wattle, or dress in the green and gold, enjoy a walk in the bush and take in some wattle splendour, make a Wattle seed cake and have morning tea, but above all, take a moment to reflect and be thankful for all we have in this beautiful country we call home.

Magpie-Lark (Grallina cyanoleuca)

Also known as mudlark, Murray magpie and Peewee.

One of the most fascinating attractions of these Magpie-Larks, and something I enjoy the most, is to listen to them sing.

They sing in duet, each partner sings their notes about a second apart, one sings, ‘peewee’ and the other responds with, ‘wit’. This singing makes it difficult to know there are two birds singing, tricky.

Other interesting points 

  • When other birds enter their territory, they will stand side by side and sing out their melody (keep away).
  • Known to have a partner for life.
  • Diet is carnivorous, consisting of a variety of small creatures, e.g. insects, spiders, worms and lizards. See them as a natural insecticide, helping to reduce the numbers of unnecessary bugs.
  • Peewee’s find their food by walking through fine soft patches of ground/grass areas.
  • They build a very interesting nest, made out of mud, and lined with fine bits of grass matter.
  • Peewee’s have up to 5 chicks with an Incubation time of 18 days, and the young fledglings are ready to leave the nest within 3 weeks.

Why are Eucalyptus Trees Magnificent?

Margaret Loveday – Monday, June 08, 2015

My passion is to entwine the ‘Threads of Love’ throughout my book series and this comes also, in the form of Love for the environment and to bring awareness of the beauty and uniqueness of the Australian Bush and its flora and fauna.

In my book ‘Emily’ I have written about Green Coastal Wildlife Park, which is a fictitious Park that showcases all the elements and philosophies that I believe would help to achieve the love and respect that nature deserves. It is an ideal ‘Natural Wonderland’, a compilation of places I have visited and enjoyed.

I would like to contribute to this awareness, by sharing on this magnificent Australian species of trees, called Eucalyptus.

Eucalyptus (Gum) trees

The Eucalyptus Trees are unique and very special trees; they are beautiful and can be found in almost every part of Australia. There are about 700 species and only 15 species of these were introduced to other countries.

The Two Characteristics of the Eucalyptus Trees:       

  1. The unique floral display is like no other tree, and
  2. The fruits (or gum nuts), that each tree produces.

These two characteristics are what makes them easy to recognise, and sets them apart.

The Flowers

Their flowers are not petals, but a ‘showy’ of numerous fluffy stamens, that come in a kaleidoscope of many colours, for example, here are some of the different colours of the flowers found around Australia:-

  • Western Australia – yellow, green, pale yellow or red orange tightly clustered flowers.
  • Queensland – red, orange or pink
  • South Australia – red, white, pale yellow
  • New South Wales – pink, white, dark pink / purplish
  • Northern Territory – scarlet flowers and others are stunning orange with bright yellow tipped stamens (look like a flame), orange.
  • Victoria – white
  • Eastern ranges to coast of mainland Australia – masses of white showy flowers
  • Sandy coastal, swampy south west corner of Australia – red
  • Tasmania – white

Eucalyptus sideroxylon

All the stamens are enclosed in a cap, composed of the fused sepals, hence the woody fruits called gum nuts.

Nearly all Eucalyptus trees are evergreen, different shades of green/blue/white in colour. Some tropical species lose their leaves at the end of the dry season, others Eucalyptus leaves are covered with oil glands, which helps to prevents water loss.

Eucalyptus Tree Identification

Due to the many different varieties ofs Eucalyptus trees, identification has been made easier and this is now done by observing the bark of the trees. This process has allowed them to be placed into five simple bark categories.

A). Bark Identification

  1. Stringybark: – consists of strands which can be pulled off in long pieces. Usually it is thick with a spongy texture. (Stands of thick long pieces – spongy)
  2. Ribbon:- where the bark comes of in thin long pieces but still loosely attached in some places. They can be long ribbons, firmer or twisted. (Long loosely ribbons)
  3. Ironbark: – is hard, rough and deeply furrowed. It is soaked with dried sap exuded by the tree which gives it a dark red or even black colour. (Hard, rough soaked sap)
  4. Tessellated:- bark is broken up into many distinctive flakes. These flakes are like cork and can flake off. (many cork like flakes)
  5. Box:- has shorter fibre’s (Short fibre’s)

Spotted Gum ForestB) Having them divided into only three main groups, helps to know what areas /locations they are found.

Three Main Groups for Location Identification

  1. Forest trees
  2. Woodland trees
  3. Mallee trees

The introduction of Eucalyptus trees into other countries

Following the Captain Cook expedition in 1770, and Sir Joseph Banks a botanist, was the driving force that subsequently started the introduction of the Eucalyptus trees to the world. Today these magnificent trees can be found in countries such as; California, Brazil, Spain, Morocco, Uganda and Israel.

The interest was due to the many valuable uses these trees provide and the importance they have economically, such as:

Being one of the fastest growing sources of wood, saw milling, pulp, charcoal, timber for building homes, bridges, furniture, musical instruments, firewood, essential oils (therapeutically), essential oils (cleaning products), essential oils (used as a natural insecticide), paper, tissue, mulch, fertiliser, dyes and more.

In Israel

These trees were recognised for their fast growth, as an evergreen tree, providing shade for smaller trees and because of the large clusters of flowers that blossom almost all year round. This added bonus has made the bees and the bee keepers very happy, producing larger quantities’ of honey for longer periods during the year.

The Eucalyptus Camaldulensis, imported from Australia was used as an aid to dry out swamps; this significantly reduced the amount of mosquitoes, thus reducing risk of malaria.

Fire

Eucalypts are well adapted for periodic fires; in fact most species are dependent on them for the spread and regeneration. They grow back very quickly. However, Alpine Ash and Mountain Ash only grow back from seeds.

Frost

Most Eucalypts are not frost tolerant, but species like the, Snowy gums, Eucalyptus paucilflora, is capable of withstanding cold, snow and frost about, -20 degrees

snow gum

Branch Dropping

Eucalyptus trees have a habit of dropping entire branches as they grow. That’s why when you visit a Eucalypt forest you see the ground littered with dead branches.  They say that some species of gum trees drop branches un-expectantly, known as “summer branch drop”, such as the River Red gums. It has been noticed to occur mostly during droughts, when trees shed whole branches to save water. Some of these branches weigh a lot, due to the high density and high resin content. Therefore, it is best not to camp under a large Eucalypt.

The Ghost gum, Eucalyptus papuana, sometimes called the ‘widow maker’, named thus because of the high number of workers killed by the falling branches, as they sat or camped underneath them. Note, these branches and even very large ones, can be shed at any time so be mindful, in particular during the summer months.

The magnificent Red Gums, trunks and branches change from orange in summer and lighter orange/pinkish grey in the winter. In December these trees are adorned with bunches of white flowers. When I see them in great numbers up high on a mountain or fly over them, it looks like snow, absolutely brilliant.

Kino

The sap which exudes from any break in the bark is called kino. This is the trees normal reaction to mechanical damage, it oozes, like the tree is bleeding and it usually is bright red in colour. Some species ooze large amounts from their wounds, but with the air and sun exposure the sap hardens.

Kino is used in different ways, for example, having a natural defense mechanism it protects the wood from ship worm and borers, and the tannin, has been used for dyeing fabrics.

Other interesting facts about the Eucalyptus trees

  • On warm days, in Eucalyptus forests sometimes you can see a bluish smog-like haze, it is the volatile oils (compounds known as terpinoids), that the leaves emit, hence the name Blue Mountains, in Australia.
  • Several Eucalypts species are among the tallest trees in the world, namely the E. Regnans, the Australian ‘Mountain Ash’ and the tallest named Centurion is over 327 feet tall, (approximately 100m).
  • The Ghost gum’s leaves were used by Aboriginals to catch fish; the leaves contain a substance that stuns the fish.
  • Didgeridoos, known as an important wind instrument, were made by tree trucks that usually were hollowed out by termites.
  • They oxygenate the air.
  • Are useful homes for many beneficial insects and other wildlife such the koala and the many varieties of birds.
  • And for us to respect, admire and enjoy.

The White-Bellied Sea Eagle

In my book ‘Emily’, the concept of ‘Green Coastal Wildlife Park’, was a perfect way of high-lighting environmental issues and subtly bringing awareness that love is an important aspect when it comes to our natural environment. This extends to respecting and embracing our natural flora and fauna that we need to protect.

Our wildlife depends on us to maintaining  the health of the environment,  and the balance of all this is  important to all our futures.  

The White-Bellied Sea Eagle also known as the White Breasted Sea Eagle.(Haliaeetus leucogaster)

                                                  They are protected by law

CCCCwhitebellied sea eagle- upcloseI call them our precious majestic bird

Short description

  • The female is slightly larger than the male, and can measure up to 90 cm long with a wingspan of up to 2.2 m and weigh 4.5 kg.
  • The call is a loud goose-like honking, especially during the breeding season.
  • A young white bellied sea eagle in its first year is predominately brown. This brown colour then starts to diminish by gradually being infiltrated with white until in reaches adulthood by the 4th or 5th year.
  • This species breeds from around the 6th year onward.
  • Their life span is around 30 years.

Their Home and Nest

  • The nest is their castle, signifying power, authority. It clearly marks their chosen territory, in other words, they are politely making it clear, ‘keep away from my property, house and family!’
  • They usually choose tall trees, often used as a perch to survey the surrounding area, near water with some forest cover. It is here where they build their nest, usually sited in the fork of large trees (mostly in sheltered eucalyptus trees), overlooking bodies of water.
  • Cliffs are also suitable nesting sites.
  • The nest is a large deep bowl constructed of sticks, branches and lined with materials like grass, green leaves (believed to be for hygiene purposes) or seaweed.
  • Yearly renovations result in nest getting gradually bigger, old nests can become enormous, some measure up to 4.5 m (14 feet) deep and 1.5 m (8 feet) wide. Now that’s pretty big!
  • A breeding pair knows their own roles to partake through the process, the male becomes more active, having fun by spending 3 to 6 weeks building or renovating the nest before his mate starts to lay her eggs.

CCCCsea eagles nest

 

 

CCCCCwhite-bellied sea eagle2nest

Breeding

  • Normally two eggs are laid and they are incubated over 6 weeks before hatching.
  • Initially the male brings food and the female feeds the chicks, both parents feed the chicks as they grow larger.
  • Hatching is 40 to 44 days and nestling 65 to 70 days. It has been recorded that fledglings are fed for about 3 months, after this, they can remain around the parents’ territory for up to 6 months or until the following breeding season.

Diet (Feeding is carnivorous)

  • They usually hunt and consume a wide variety of animal prey, mainly aquatic animals, such as; fish, eels, porcupine fish (deadly to humans), water rats, turtles and sea snakes. Other animals they are know to eat, is the blue tongue lizard, and some birds.
  • Eagles often catch a fish by flying low over the water and grasping it in its talons.  On sunny days it flies directly into the sun or at right angles to it, so it doesn’t cast a shadow over the water and so, sneak up on its prey.
  • They are skilled hunter’s, and if they are desperate for food, they can attack prey up to the size of a swan, and even eat sea gulls.
  • They also feed on carrion such as dead sheep, birds and fish found along the waterline.

Interesting facts  

Much of the white-bellied sea eagle’s behaviour, particularly breeding, is not well known.

  • Nests are a territorial marker and it is used for breeding, feeding, protecting the family, protection from any intruder(s), a sleeping and surveillance platform.
  • Eagles have one mate for life, however if one dies it quickly seeks a new mate.
  • Courtship is for life and it increases during the spring.
  • Eagles are often seen perched high in a tree, or soaring over waterways and adjacent land.
  • Eagle’s like to breed and hunts near water, because their main diet consists of fish.
  • The male’s honking call is higher-pitched, more rapid and is among the loudest and furthest –carrying of all the Australian bird calls.
  • Some nest sites are continuously occupied for many years, (e.g. 50 yrs).
  • They are found in higher numbers where there is little or no human impact or interference.
  • Estuaries are a favourable habitat.
  • DDT was once a widely used pesticide in agriculture and was found to have a negative affect on wildlife, particularly egg thinning and subsequent breakage.

The eagle is revered by indigenous people in many parts of Australia, and is the subject of various folk tales throughout Australia.

The white bellied sea eagle was and is important to different tribes of indigenous people across Australia.

Examples from Wikipedia:

  • The guardian animal of the Wreck Bay aboriginal community, it is also the official emblem of the Booderee National Park, and
  • Botanic Gardens in the Jervis Bay Territory.
  • A local Sydney name was gulbi, and the bird was the totem of Colebee, the late 18th Century indigenous leader of the Cadigal people.
  • The Mak Mak people of the floodplains to the SW of Darwin in Northern Territory, who recognise its connection with ‘good country’.  It is their totem and integrally connected to their land..
  • The Umbrawarra George Nature Park was a Dreaming site of the bird, in this area known as Kuna-ngarrk-ngarrk.
  • It was symbolic to the Tasmanian indigenous people – Nairanaa was the name used there.
  • Known as Manulab to the people of Nissan Island, the bird is considered special and killing is forbidden. Its calls at night and it is said to foretell danger, and seeing a group of calling eagles flying overhead is a sign that someone has died.
  • Local Malay folk talk tales tell of the bird screaming to warn the shellfish of the turning tides, and a local name burung hama siput translates as ‘salave of the shellfish’.
  • Maharashtra coast, their name is kakan and its call is said to indicate the presence of fish in the sea.

Love  Nature

Love our environment and look after it, let us keep our footprints as light as possible in this planet we call home.  

Another reason why I have written ‘Emily’, and placed the characters, in an Australian beach/bush setting, was to bring notice to the beauty of the nature that surrounds us all, to love nature is to care for it, even in the simple things we all do everyday.  Like reducing chemicals on our garden and changing our washing powder, all these small actions when we get together is a huge action towards a better environment and that in turn protects our own health, everyone around us, our pets and native animals.  Margaret Ann Loveday

The Wonders Of The Estuary

This is an excerpt from Emily the book – ‘The Estuaries Ecosystem Tour…presented by Anthony and Kelly’ (Wildlife Rangers at the ‘Green Coastal Wildlife Park’)

Walking along the boardwalk, Ranger Anthony requests for everyone to stop and admire all the nature around them…

“Surrounding the lake we have swamp mahogany and lots of common reed….. these estuaries are the tidal mouth of the large river,  where the tide meets the stream… They are full of nutrients making the estuaries the most biologically productive natural habitats in the world.”

What is an Estuary?

An estuary is a partially enclosed body of water along the coast where freshwater of the rivers and streams meet the saltwater and mixes; the lands around these are places of transition.

Eustry1

 Avoca Lagoon, was first settle by the Awabakal Aboriginal people, and the name Avoca is Celtic for the ‘Great Estuary or ‘Where the River meets the Sea’.  

The Importance of the Estuary They are fundamental and invaluable, supporting life upon which all organisms depend’.  The two services they provide, are:  

  • Water filtration, and
  • Habitat protection. 

Eustry2

The sheltered waters of the estuaries are the home to countless plants and animals, that like to live in its briny environment, for example:  shellfish, worms, and other invertebrates living in the mud, which attracts many different birds, including migrating birds. There are a variety of fish, sea horses, lizards and snakes and many, many other animals.  

Healthy estuary conditions attract dolphins as they are vital for their food source, health and very survival.  

Habitats associated with estuaries, such salt marshes and mangrove forests, act like enormous filters.  As water flows through the salt marsh, marsh grasses and peat (spongy matrix of live roots, decomposing organic matter and soil), filtering pollutants such as herbicides, pesticides, and heavy metals out of the water, as well as excess sediments and nutrients.  

One reason that estuaries are such productive ecosystems is that the water filtering through them brings in nutrients from the surrounding watershed.  In addition to nutrients, the same water, however, can at times bring with it, all the pollutants that were applied t the lands in the watershed.  For this reason, estuaries are some of the most fertile ecosystems on the Earth, yet they may also be some of the most polluted, and this is concerning.

Estuaries and their surrounding wetlands are also buffer zones.  They stabilize shorelines and protect coastal areas, inland habitats and human communities from floods and storm surges.

When flooding does occur, estuaries’ habitats also protect streams, river channels and coastal shores from erosion caused by wind, water, and ice.  

Unlike economic services, ecosystems services are difficult to put a value on, but we cannot do without them, and thus are essentially priceless.

Love  Nature

Love our environment and look after it, let us keep our footprints as light as possible in this planet we call home.  

Another reason why I have written ‘Emily’, and placed the characters, in an Australian beach/bush setting, was to bring notice to the beauty of the nature that surrounds us all, to love nature is to care for it, even in the simple things we all do everyday.  Like reducing chemicals on our garden and changing our washing powder, all these small actions when we get together is a huge action towards a better environment and that in turn protects our own health, everyone around us, our pets and native animals.  Margaret Loveday
