SPIRIT OF THE FOREST

The Atherton Performing Arts will be presenting "Spirit of the Forest" at Merrilands on 7th and 8th September, in the evenings and on 9th September in a matinee. This show will be an hour and a half feast of live music, song and dance and was written and composed by local tablelander Pat Schafer.

The scene is set in the beautiful tablelands rainforest whose colourful inhabitants are the main characters. The dramatic but humorous show provides great scope for many varied drama forms, mime, gymnastics, circus and physical theatre.

TREAT will be assisting with the supply of trees for atmosphere and will have a static display featuring Mabi forest.


ANNUAL GENERAL MEETING

A New Time and Place

The 25th AGM will be held on 14th September in the Stan Moses Hall at the back of the Anglican Church in Vernon St. Atherton, commencing at 7.30pm. We trust that the weather will be warmer than in August when we've previously held the AGMs in Yungaburra.

This year we are privileged to have David Johnson, local geologist and author of "The Geology of Australia", as our guest speaker. David is going to talk about "Climate Change - Facts and Implications".

'Although climates have fluctuated repeatedly throughout geological time, the present situation should not be dismissed as just another normal episode. There is strong evidence of the human cause of the global warming, with increases in temperature and decreasing rainfall for much of Australia. This has serious implications for water and food supplies, and management of the land and vegetation.'

Annual reports by the President, Treasurer and Nursery Manager will be followed by the election of new office bearers and committee members and a General Meeting. Members are reminded that they must be financial when voting for the new committee.

Subscriptions will be accepted at the AGM.

There is a supper afterwards and plate contributions are appreciated.

All are welcome to attend.


Pioneers

- and the value of Live Fast, Die Young

Nigel Tucker

By definition, pioneers are those striking out before the main body - laying the road for the main advance - foot-soldiers, explorers, individuals with insight, and even plants. Pioneer plants are part of most plant communities, and they all share some or all of the following traits;

  1. plants germinate (and persist) only in conditions of disturbance
  2. rapid growth and early mortality (10-100 years)
  3. prolific flowers and fruits appear from an early age (3-6years)
  4. limited energy is diverted to chemically protecting foliage from browsing animals
  5. in woody species, the timber is light and breaks down quickly
  6. seeds are surrounded by an impermeable coating that allows them to persist in the soil for some years
  7. they change the nature of their immediate surrounds such that their offspring can't exist in the same spot unless disturbance occurs
  8. specialised mutualistic associations with particular birds, animals and insects are rare, and most pioneers have many dispersers and pollinators
  9. most species occur across a wide range of soil types and altitudes

Traits such as these are typical of what are termed 'r strategists', generalist species whose life cycle is rapid (live fast, die young), as opposed to 'k' (for constant) strategists who lead longer, less extravagant life styles. These characteristics provide restoration plantings with features that are important in ensuring that the right 'recovery trajectory' occurs at a site, both at the time of planting and for many decades into the future. Starting at the top of the list, let's examine some of the ways pioneers work for you in a restoration planting.

Once you replant it is unlikely that pioneer species will germinate within your plantings - it is more likely they will germinate away from the site in an area where no pioneer plants are present. This means that regrowth is started somewhere else and new patches of native vegetation regenerate 'free of charge'.

Rapid growth is important for two reasons - weed suppression is the first and most obvious, as shade and root competition act to get rid of the grasses. The second reason why rapid growth is important is because of the structural complexity created by 'taller faster' growth, providing better perching sites for birds and creating more feeding places for birds and animals simply because there is more vertical space. Early mortality is just as important. If you plant only mature phase (long lived) species it will be many years before these plants shed branches, and many more before they begin to die naturally. This means that the ground storey will lack branches and logs which are vital for providing cover to lizards, skinks, small mammals and insects. Equally, when the pioneer plant dies it creates a light gap and the many plants which have begun to regenerate beneath are stimulated to fill the gap. This growth spurt creates even more structural complexity because these clumps often harbour new life forms such as vines, ferns and understorey plants which have been dispersed into the plot by perching birds.

Flowers and fruits are important resources which wildlife doesn't ignore. Providing birds, animals and insects with resources is the best way to give them habitat and get ecosystem services like dispersal and pollination kicking along. Most pioneer plants fruit very early in life compared to mature phase species, and many have fruits which are very attractive to seed dispersers such as Fruit Pigeons and Victoria's Rifle-bird (Ptilorus victoriae). The majority produce regular and abundant seed crops which are seasonally important. For instance, Wompoo Pigeons (Ptilinopus magnificus) rely heavily on the fruits of Celery Wood (Polyscias elegans) during May, June and July, and Cassowaries have an obvious preference for Blue Quandong (Eleaocarpus grandis) wherever it occurs. For Giant White-tailed Rats (Uromys caudimaculatus), the Candle-nut (Aleurites rockinghamensis) is a high value fruit which attracts large numbers of animals.

Pioneers always direct resources to maximum growth, not long life, so leaves and twigs have fewer chemical defences and are often fed on by many insects and vertebrate animals. Pademelons (Thylogale stigmata) are gluttons for the foliage of Bleeding Heart (Homolanthus novoguineensis), and this pioneer is also a preferred food plant for the larvae of the enormous Hercules Moth (Coscinocera hercules). Because resources are not directed to growing strong durable wood fibres, they are more prone to blowing over, and the timber rots more quickly once the dead tree has fallen. Rotting wood is vital for the beetles that go on to create nest hollows in trees for possums, for the Striped Possums (Dactylopsila trivirgata) that eat the beetles, for hollow logs to be used by ground-dwellers, and for nutrients to be cycled back into the soil.

The small hard seeds of mature pioneers rain into the soil on an annual basis and many are incorporated into the soil seed bank. With their impermeable coating, these seeds can lay dormant in the soil for years until sufficient disturbance stimulates their germination. The disturbance needed is significant - generally only huge tree falls, fires, floods, cyclones and landslides trigger germination (add clearing and logging to that). In restoration plots, the ability of pioneers to germinate after this type of event is a kind of insurance policy as well as a natural recovery mechanism. Locally, it has been very interesting to watch the rapid germination and growth of pioneer plants in cyclone damaged restoration plots. This will undoubtedly contribute to less weed invasion and faster recovery within these plots. Such resilience is due entirely to the dispersal and incorporation of pioneer species into restoration plots.

However if disturbance is only 'average', the death of a pioneer tends to introduce a new class of plant - the mature phase species, the 'k strategist' who uses other adaptations to ensure its ongoing reproduction. The pioneer almost never replaces itself because it has fundamentally changed the environment in which it first started its life. The site of massive disturbance is no more, a shadier and moister site is now more effectively colonised by mature phase species which will go on to dominate the site, at least until another massive disturbance event occurs and the whole process begins again.

For tree planters, the final trait is perhaps the most valuable. Pioneer plants tend to be quite unspecialised and most tolerate a wide range of conditions. This includes a large amount of variation in soil type, rainfall, altitude and even drainage. Moreover they attract a wide array of potential pollinators and dispersers, and most are easy to germinate and grow yourself. This means pioneers can be planted in almost any locality and once established you can sit back and watch them do the work. Pioneers can comprise between 30% and 100% of the total trees you plant, depending mainly on the distance to the nearest patch of vegetation. Talk to Lake Eacham Nursery staff for more details on the best ways to use this important group.


VALE JAMES (JIM) HORSEMAN

Nigel Tucker

Many TREAT members will recall with great pleasure the company afforded by Jim Horseman at the Lake Eacham Nursery and his great contribution to the cause of tree-planting. I met Jim in 1985 when he visited the old nursery chasing trees to plant on the banks of Leslie Creek, on his Ball Road property. This was the start of a 20 years plus association with Jim, and during that time his commitment remained unchanged. For most of my 20 years at the Lake Eacham Nursery, Jim Horseman and Stan Crichton were always the first Friday morning arrivals at 7am promptly, without exception. Both were integral to getting Fridays on the road - Stan would start making potting mix and Jim and I would start organising the trays of seedlings for the day's potting effort, and once sorted Jim would assume responsibility for the rest. Jim would take new members under his wing and gently scold a potting technique which was not up to scratch, and alert us to anything which he knew needed our attention. On planting days Jim's energy and knowledge were put to good use, and many QPWS Nursery staff relied on Jim to ensure that small details were not ignored, and every chance was given to each plant in the hope of its long life and contribution to the future. Jim's long life made a huge contribution to the future, and his service to the community as a whole was an inspiration. Many of Jim's closest friends from TREAT were at his funeral - Barb Lanskey, Barb Walsh, Karleen Welton, John Hall, Pete Snodgrass and Nick Stevens to name a few. Along with all of them, TREAT extends its thanks to Jim's family for the time he devoted to TREAT, and for his great service to the environment.

FNQ NRM Ltd now has a new name. As from 30th June, the official name is: FNQ NRM Ltd trading as terrain Natural Resource Management

For all day-to-day communication they will be: terrain Natural Resource Management

All phone numbers and mailing addresses remain the same but they will have a new website: www.terrain.org.au

One of the main reasons for changing the name was to prevent people confusing them with a government department (like the Dept. of Natural Resources and Water).


Offsetting your Carbon Footprint

-1- Colin Hunt

Don't buy dubious offsets on the internet!

Grow your own offsets on the Tableland!

To tackle climate change we need to reduce the amount of greenhouse gases we emit to the atmosphere.

Everything we consume generates CO2-e in its manufacture and transport. If we practise the three Rs: Reduce, Reuse and Recycle, we will reduce our carbon footprint.

The main greenhouse culprit is carbon dioxide (CO2), but there are other more powerful greenhouse gases, e.g. methane, that need to be accounted for. We account for these other gases by converting them to their carbon dioxide equivalent, CO2-e.

We find it difficult to reduce car and air travel - large generators of greenhouse gases. Cars are needed for work and recreation, and we now travel more by air because of cheap fares. Such emissions that we cannot reduce can be offset by planting trees.

Carbon dioxide is converted to carbon by tree photosynthesis, and stored in the leaves, branches, trunk and roots. Carbon also accumulates in the soil and in litter.

The first chart show the amount of atmospheric CO2-e captured over time by planting 330 mixed species rainforest trees on 1/10th of a hectare of grassland (or an area 33mx33m) at 1.75m spacing.

Chart 1: Reduction in tonnes of atmospheric CO2-e, by year to 2050, by planting 330 (0.1 hectares ) mixed species rainforest trees, in 2008, on the Atherton Tableland

Reduction in tonnes of atmospheric CO2-e

Note: The Carbon Toolbox of the Australian Greenhouse Office is the source of the forecast of total CO2-e captured in a Tableland rainforest reforestation as carbon.

By year 2050 it is forecast that some 55 tonnes of CO2-e will have been sequestered in the 330 trees planted and by the trees that have been introduced naturally.

This estimate is for basaltic soils near Yungaburra but will apply to most Tablelands areas that carried rainforest.

Steps to offsetting your travel emissions

Step 1

Go to www.terrapass.com to calculate your car and air travel emissions for a year, in metric tonnes

Step 2

Decide your offset target year. This example adopts a target year of 2050, but if your target is year 2025 you will need double the number of trees (see Chart 1).

Step 3

If 2050 is your target, use the second chart below to calculate the number of mixed species rainforest trees to plant in 2008.

Chart 2: Tonnes CO2-e emissions offset in year 2050 by number of trees in a mixed species rainforest planting, Atherton Tableland

Tonnes Carbon Dioxide equivalent emissions offset in year 2050

It should be emphasised that you will need to not only prepare the site, acquire, plant and mulch the trees but also undertake vital weed and grass control for three years. However, you may be able to join with others to plant and maintain a greater area. A reminder that you need to budget for fencing your planting to keep out stock.

Eacham Shire Nursery should be contacted as soon as possible to provide mixed rainforest trees in early 2008, assuming that planting will take place in the next wet season. The nursery will advise on the appropriate type of trees for the location, for example type 5b or 1b.

TREAT can advise you on tree planting and maintenance, and may be able to put you in contact with a landowner willing to accommodate a group planting.

An annual commitment by a group to voluntarily offset its emissions by undertaking rainforest reforestation could - at the same time as offsetting its greenhouse emissions - make an important contribution to Tableland habitat. Strategic planting could form a wildlife corridor or repair a river bank.

Water Quality Update

Noel Grundon

In the April - June 2006 issue of the Newsletter, Colin Hunt, Simon Burchill and I wrote an article titled What About Water Quality? In it, we described some of the beneficial effects that we assume occur when TREAT and similar groups revegetate riparian environments such as Peterson Creek. But is there any evidence that replanting riparian areas improves the quality of the water in tropical riparian environments?

To try to answer this question, TREAT obtained grants to purchase equipment to measure some parameters of water quality. With assistance from David Green of QDPI & F, TREAT conducted a workshop in May 2006 on the benefits of improved water quality. This workshop outlined the many parameters that define water quality. With David Green's encouragement, a small group comprising Bryony Barnett, Barbara Lanskey, and myself, and in consultation with Colin Hunt, have met regularly with David to complete a step-by-step process to design a water quality monitoring program to measure some aspects of water quality along Peterson Creek. Overall, a series of questions had to be addressed.

Why are we monitoring?

The simple answer is to find out if TREAT's activities in revegetating areas such as Peterson Creek have any effect on the water quality of the stream. When applying for grant moneys, TREAT always claims to be improving water quality of riparian environments, but we have no direct evidence that this occurs. It is time that TREAT obtained direct evidence of the effects of its activities on water quality - before the granting agencies start asking awkward questions.

Who will use the data?

While the data will be used firstly by TREAT, it will be available to other Tableland tree-planting groups and organisations that have similar interests to TREAT in demonstrating the effect of revegetating riparian areas on the quality of stream water.

How will the data be used?

The data from the monitoring program will be used in the first instance to support TREAT's applications for funds, and in the second instance to assist in improving the methods used in revegetating riparian environments. For example, losses of soil can occur in heavy rainfall events. We know that when stormwater hits a buffer strip of vegetation, it slows down and drops its silt load and gives up some of its nitrogen and phosphorus to the buffer vegetation. But is a strip of trees an effective buffer strip or should we be using creeper-like ground-cover species on the edge of the trees to trap any soil moving downhill? Are our buffer strips of trees wide enough to be effective buffer strips? Further, do deep-rooted trees stop losses of soil from the top 10 cm of soil under the trees? Measurements of the turbidity of stream water, and of soil losses or accumulation, with erosion pins placed in the buffer zone, will provide answers to these questions and allow TREAT to improve its revegetation methods.

What will we monitor?

What do we mean by "water quality"? Pure water is defined as a tasteless, odourless liquid at normal temperatures and pressures. Chemically, it contains only hydrogen and oxygen in the ratio of two hydrogen atoms to one oxygen atom. But even rainwater contains some contaminants from dust and chemicals in the air and compounds of nitrogen produced by lightning in storms. When rain falls and water soaks into soils or runs overland, both organic (e.g. pesticides; humic acids from decomposing plant materials) and inorganic (e.g. from fertilisers) compounds dissolve in the groundwater or stream water and further contaminate the water. Solid materials such as particles of soil or plant material can be carried into stream-water during heavy runoff. All of these soluble and solid contaminants can cause environmental damage to plant and animal life - if they occur in sufficiently high concentrations.

The workshop in May 2006 identified a large number of physical, chemical and biological parameters that can be used to measure the quality of water in tropical riparian environments. From TREAT's viewpoint, it is practical to select only those that affect biological use of the stream water. Initially, we have chosen to complete monthly measurements for: pH, temperature, electrical conductivity, total dissolved salts, turbidity and dissolved oxygen. In time, we might be able to include dissolved nitrate and dissolved phosphate, and, with assistance from other interested organisations, complete some sampling for stream biota such as macropods, fish, insects and insect larvae. With sufficient funding, we may undertake an annual complete chemical analysis of the water.

What methods will be used?

To employ an analytical laboratory to measure the above parameters on a monthly basis would be very costly. Therefore, TREAT purchased accurate, portable equipment that will measure pH, temperature, electrical conductivity, total dissolved salts, turbidity, dissolved oxygen and dissolved nitrate. To ensure accuracy and quality of data, standards have been purchased against which the measuring kits will be calibrated before each monthly measurement of water samples.

What data quality do we need?

Although TREAT's testing kits are portable and are designed for field use, they produce laboratory quality data. With regular recalibration against high quality standards, and with care and attention to detail during sampling and measurement, good quality data can be assured. Hence the data obtained from TREAT's program will be much better than that from previous water monitoring programs conducted by community groups, and equates to that obtained by many research programs. This is an advantage because our data can then be compared directly with data from other water monitoring programs undertaken in Far North Qld by groups such as QDPI & F and JCU.

Where will we monitor?

By selecting sampling sites above and below revegetated areas or agricultural and urban development, we may obtain answers to the effects of revegetation or development on water quality. For example, it is often stated that excluding cattle from streams by fencing and the provision of alternative watering points, are effective methods of reducing stream pollution - but does this occur along Peterson Creek? By measuring water quality from areas where cattle are not excluded and from where they are excluded, we might get some answers to this question. Likewise, by comparing water quality in areas not revegetated against that in areas where revegetation has occurred, we might demonstrate the effects of revegetation on water quality.

TREAT also needs to consider health and safety factors for those people involved in collecting the water samples. With assistance from David Green, TREAT investigated a number of locations along Peterson Creek looking especially at ease and safety of access.

Another factor that had to be considered was the availability of baseline data on water quality in Peterson Creek before any revegetation had taken place. Fortunately some moderately reliable data was available from a Waterwatch program conducted in the mid-1990s where samples had been collected from four sites along Peterson Creek.

TREAT identified four locations along Peterson Creek where testing the quality of the water can be safely undertaken, and which would provide information that, over time, would provide some answers to the question "Does revegetation of tropical riparian environments improve water quality?". Two of these sites are the same as those used in the Waterwatch program; on Peeramon Road, and at the Gillies Highway Bridge. The other two sites of the Waterwatch program were considered as being too unsafe for easy access, and were replaced with Frawley's Pool (as an example of an environment that might have input from urban development), and Lake Eacham (an example of a pristine environment with no inflow from agricultural or urban development).

Who will be involved?

TREAT is now ready to embark on a comprehensive monthly testing of the water quality at these four locations along Peterson Creek. To do this, two members will be required for one morning each month, to calibrate the testing equipment, to collect water samples, to complete the measurements and to record the readings.

How will the data be managed?

The data will be initially collated onto record sheets and in Excel files.

How will we ensure data credibility?

Baseline data has been collected on the water quality of Peterson Creek in the 1990s Waterwatch program. This information will be compared against the new data. However it will be some time before trends will become apparent - two years at least before any conclusions can be made. During this time, TREAT will be in regular contact and discussion with people in Eacham Shire Council which regularly tests the water supply from Peterson Creek, State Government agencies such as QDPI & F, non-government organisations such as terrain NRM and local Landcare groups who are undertaking similar water quality monitoring programs.

When sufficient data has been accumulated over at least 2 years, it can be compared against existing guidelines developed in the National Action Plan for Salinity and Water Quality (Water Quality Program) to determine if the water quality in Peterson Creek is acceptable, and to examine the effect of revegetation on water quality.


RAINFOREST FORUM

Barb Lanskey

"Recovering Rainforest" was the theme of the 2007 Qld Rainforest Forum held in Brisbane from 25th to 27th June. There were two days of talks followed by a field day. I gave a 15 minute presentation about our Peterson Creek project and TREAT prepared a large poster about the project for display.

It was a great opportunity for TREAT to showcase some of its work in our 25th birthday year and gave me a chance to learn about other community groups and some research projects. As talks were held in concurrent sessions (apart from keynote presentations), I was able to attend only half of them and had to miss some interesting scientific talks. There were four Discussion Forums but I had to forego "Weeds" in favour of "Rainforest Conservation on Private Land".

Involving the community and private landholders in rainforest conservation was a recurring point throughout the Forum. Extensive clearing (of all types of rainforest) has generally left only small fragments everywhere, and much of what is left is on private land. By encouraging landholders to understand the importance of their "patch" and by investing public money in the retention and expansion of these fragments, corridors can be created to allow animals and other wildlife to move through the landscape.

"Climate change and Rainforest Conservation" was the subject of the first Discussion Forum, and encouraging resilience of forests rather than preserving them, seemed the way forward. In the last Discussion Forum, "Rainforest Wrap Up", it was clear much more research was needed to understand all the creatures accounting for the biodiversity of forests, in order to be able to document the effects of climate change on the biodiversity. Observations of species shows climate change is happening now. Topics such as fire, carbon, funding and regulations were all part of the discussions.

The field trip I chose the following day was to the Sunshine Coast areas of Maleny and Kin Kin. It was most interesting to see how other landcare groups operated and their level of community support, and to talk with people doing revegetation work similar to TREAT's work.


NURSERY NEWS

Peter Snodgrass

Some say it was the coldest, frostiest day for five years and some say twenty, but either way Winter is here in full swing. The nice side to frosty mornings is that of the beautiful days that follow, and I'm sure everybody is enjoying them to the full. There is one other good side to the frost and that is that a lot of unwanted weeds were wiped out. Unfortunately we suffered a lot of frost damage that was fairly indiscriminate throughout our revegetation sites, particularly the younger sites such as Peterson Creek 2007 and 2006 as well as Massey Creek 2007 on park estate. This is understandable when we see that, because the frosts were so severe, even trees that are over five and ten years old received substantial damage. It is difficult at this stage to say what has died and what will survive. Only time and the arrival of Spring can answer this question. Spring will see us all busy anyway, with the remainder of trees to be planted on the 2007 site at Peterson Creek, when we can also carry out any infill planting required.

We will be compiling a list of the trees that have been most tolerant to the frosty conditions, and will include the results in the next edition of Nursery News.

Thanks to all those who have been diligently weeding, sizing and consolidating out in the nursery hardening bays. These efforts have been very noticeable as well as greatly appreciated. There is always so much to do in the bays to ensure that we keep producing a high standard of trees. If there are people who would like to learn more about the how and why these maintenance procedures are so necessary, we will present a walk and talk around the facility to explain more about plant care in the nursery on Friday 10th August after TREAT smoko. Contact TREAT or the nursery staff if you are interested as 20 to 25 people is an appropriate limit on numbers.

Thanks again to all those who have been assisting with this task to date, and keep up the good work. We would love to see some new faces in the nursery on Friday mornings if there are people who find themselves with a little time to spare.
