Tree identification and seed propagation w/shop

This popular workshop is being held again at the nursery. Botanist Dinah Hansman will be presenting the tree identification session, showing how to identify trees from leaf features, and Peter Snodgrass will present the seed propagation session, showing the different seed types and how to germinate and grow them. The workshop is held in two sessions separated by a morning tea provided by TREAT. The workshop is free and open to anyone, but places are limited, so please register with Barbara Lanskey (ph 4091 4468) if you wish to attend. The workshop is scheduled to finish at 12.30pm.

Revegetation workshop

This workshop is held at Freemans Forest Nature Refuge, where hole digging and planting can be demonstrated. An information session is held first, to talk about what is involved in site preparation and maintenance as well as the planting of trees. Mark McCaffrey and Peter Snodgrass give advice from their extensive experience and impart the latest information on herbicides and fertilisers. Notes are provided and a morning tea is held after the information session. The workshop is free and usually finishes about midday. Please register with Barbara Lanskey (ph 4091 4468) if you wish to attend. Freemans Forest NR is on Cutler Road off Lake Barrine Road.

Christmas/New Year

The Christmas break-up party will be held on Friday 13 December. TREAT buys some platter goodies for the occasion and some members bring their special cooking. The QPWS staff from next door come over and we indulge in celebratory fashion while the food disappears. The nursery will still be open for a working bee on Friday 20 December but will be closed for the Christmas/New Year period. Working bees start again on Friday 3 January.

Carbon Farming article - Correction

Cath Moran

After it went to press, we were queried by a careful reader about the cost scenarios printed in the carbon farming article in the previous TREAT newsletter. It was good advice that the figures shown in the table should not be used to make investment decisions, since they had been miscalculated in several of the scenarios. Basically, we hadn't increased the planting costs as the size of a project increased, which meant that we increased income but not costs in larger project areas. While there probably is an economy of scale achieved in planting larger areas, it wouldn't be this large.

The correct figures were printed in the background report. We apologise for any confusion or unrealistic hopes our error might have caused. The corrected calculations are printed in this edition, along with the matching interpretation. For more context, refer to the longer article in the Dry Season 2019 edition.

Factors affecting the cost and income of carbon farming using biodiversity plantings

In the Freemans Forest pilot project we looked at various scenarios that had different combinations of the main factors that affect economic returns from carbon farming using biodiversity plantings. The two main factors that affect costs are 1: planting costs (i.e. the extent to which external funding covers site preparation, planting and maintenance) and 2: the cost of the compulsory audit. In the calculations below we've used an approximate planting cost of $33,000 per hectare, comprising site preparation ($2,200), seedlings and planting ($17,800) and maintenance until canopy closure ($13,000), though we know this can vary depending on site conditions, weather and other factors. We've presented figures here based on two audit cost scenarios - High ($50,000) and Low ($30,000) over the project lifetime. For community-based, biodiversity planting carbon farming projects it might be possible to negotiate lower audit costs.

The two main factors that affect the income for carbon farming projects are 1: the size of project and 2: the price received for carbon credits. Increasing project size directly increases income because the number of carbon credits earned increases proportionally with size. Also, the cost per unit area of audits declines as project size increases. However, unless planting costs are fully covered by funding, increasing the project size also increases the cost of establishing the planting (by $33,000 for every additional hectare).

The table below shows a selection of different plausible scenarios resulting from different project characteristics. Scenarios 2-13 mostly show the minimum project size (rounded up) that would be needed to deliver a positive economic return on a project as the other characteristics vary. There are obviously many other possible values for characteristics, as well as additional costs that could be included to understand the economic outcomes of projects with different characteristics. We've chosen to present these ones to highlight the influence of changing certain characteristics. During the pilot project we developed a calculator that can be used to determine economic outcomes by entering any value for cost of planting, audit cost, project size, carbon price, as well as things such as administration costs.

This table gives a guide to economic outcomes under selected plausible scenarios resulting from different project characteristics. The possible values for each of the factors are:- 1: Funding for planting (Full (all costs covered), Partial (maintenance not covered) or None); 2: Audit costs (Low or High); 3: Carbon Price (Low, High or Very (V) High); and 4: Project size. In all cases, it's assumed that the project sequesters 790 tCO2-e per hectare over 25 years. It's assumed that the full cost of biodiversity planting is $33,000 per hectare, though we know this can vary depending on site conditions, weather and other factors. Administration and other costs are not accounted for. ACCUs are Australian Carbon Credit Units. This information is a guide only and should not be used as a basis for business or investment decisions.

A few hectares of biodiversity planting could deliver economic returns as carbon farms

Because the number of carbon credits earned from a project increases with its size (i.e., a two-hectare project earns twice as many ACCUs as a one-hectare project), the costs of auditing may fairly rapidly be offset in larger projects, but only if there is funding to cover planting and a high price is paid for carbon credits.

Scenario 1 in the table shows that, for a small project only one hectare in area, it wouldn't be possible to break even over 25 years, even if all planting costs were covered by grants, audit costs were low and a high price was paid for carbon. By contrast, a two-hectare project would at least break even under the same conditions (scenario 2) and could potentially yield substantial returns if high prices were paid for carbon credits (scenario 3; more on higher prices for carbon credits later).

If audit costs were high, a project approaching 4 ha would be needed to turn a profit if the carbon price was low (scenario 4), while a 3 ha area would deliver a substantial return if the carbon price was high, even with a high audit cost (scenario 5).

Under a scenario of low costs and high income, 2 hectares of biodiversity planting could deliver $17,400 over 25 years. Increasing the size of a project with these characteristics would continue to increase the profit margin assuming constant planting (zero) and audit ($30,000) costs.

A carbon farming project area could include multiple different planting areas on one property, or even across different properties. Combining different planting projects into one carbon farming project is called 'aggregation' in the program and could be a way to use typically small biodiversity plantings to get the economies of scale needed to deliver economic returns on carbon farming projects.

In scenarios where there is no funding for planting (#scenarios 6-9 in the table), ), increasing the project size does not offset costs because of the increasing cost of establishing the planting (scenarios 6 and 7).

If there was no funding for tree planting, it would only be possible to break even financially as a 1 hectare biodiverse carbon farm if the price paid for carbon credits was much, much higher than it is currently (i.e., $80/ACCU or $106/ACCU, for low and high audit costs, respectively; scenarios 8 and 9).

If there was no funding for tree planting, it wouldn't be possible to break even financially as a biodiverse carbon farm andunless the price received for carbon credits was 4-5 times higher than it currently is.

The thing with biodiversity plantings on the Tablelands is that a substantial proportion of the costs is usually covered by funding from grants, and community volunteers contribute generous amounts of time and labour; in the nursery, doing site preparation, and planting. While funding for tree planting appears to be declining, tree planting has been established in Australia's consciousness as providing society with environmental, economic, social and cultural benefits, and it seems likely that tree planting projects will continue to be funded, at least in part.

If there is a shortfall in funding, it's often for ongoing maintenance - anyone who's planted in the tropics knows the outcome of ignoring weed control for a wet season. Economic returns on partially-funded projects where ongoing maintenance is a cost to the project are shown in scenarios 10-13.

Three hectares is enough to generate income if the carbon price is high and audit costs are low (scenario 11); 5 ha is needed if the audit cost is high (scenario 13). However, with a low carbon price, large areas of 11 or 18 hectares would be needed to break even, with low and high audit costs (scenarios 10 and 12, respectively).

Connectivity for Wildlife - Over and Under Roads

Angela McCaffrey

In the previous newsletter I wrote a short piece about the use of the tunnels under the East Evelyn Road with a photo of two Coppery Brushtail Possums coming face to face on the rope strung through one tunnel. Writing that short article made me think about the great work that is being done to address the challenges wildlife face when roads cross the wildlife corridors we plant on the Atherton Tablelands and beyond. There are many scientific papers covering this subject with examples from around the world but here I want to concentrate on our small area and look at it in my usual non-scientific way for those of us who appreciate just the beauty and emotional response to the tenacity of animals to overcome huge hurdles, and the human intervention to help them.

One recent example is the rope bridge strung over Kenny Road connecting both halves of the Rock Road Corridor where the Lemuroid Leap Nature Refuge gets its name from, the idea of assisting Lemuroid Ringtail Possums to cross the road. Tree Kangaroo and Mammal group (TKMG) along with South Endeavour Trust were the drivers of getting this rope bridge. It was provided by TKMG and installed by Ergon, free of charge I should add, so we have been waiting eagerly to see how long it would take for possums to start using it. There is a photo of a Green Ringtail Possum at the start of the rope on the 2012 planted side, facing towards the 2014 plantings on the other side of the road. Recent research has shown that in the space of one week, possums of three species used the ropes guiding them up to this crossing point a staggering 58 times. We don't know how many went on to use the bridge but one would have to think more than one did. As wonderful as this is, what we really want is for the planted trees to extend out across the gap and touch each other, providing a wide expanse of canopy closure across the road so that the animals can cross at any point. Tablelands Regional Council is committed to managing roadside vegetation in a sensitive way at such environmentally important spots.

The photo in the previous newsletter came from camera traps set up by South Endeavour Trust in the tunnels under the East Evelyn Road. Now that they own the properties either side of the road, they wanted to see what, if anything, was using the tunnels. It didn't take long to see that dozens of animals make daily crossings using both the floor of the tunnels and the rope passing from trees near the entrances through the tunnels. More photos from the cameras include one of a Long-tailed Pygmy Possum.

Seeing how quickly and regularly animals use these man made structures, encourages TREAT to get a similar rope bridge installed over Lake Barrine Road where it passes Freemans Forest NR, to enhance the connectivity currently provided by the culverts under the road at Peterson Creek. We look forward to publishing photos of animals using such a bridge in the future.

2019 AGM Report

Barb Lanskey

TREAT's 37th AGM was held at the Yungaburra Community Hall on the evening of Friday 6th September and only 25 people attended (with 8 apologies). The Nursery Manager's report was presented by Simon Burchill for Nick Stevens who couldn't attend. Production and Distribution figures for the nursery are listed in Nick's 'Nursery News'. Mandy Bormolini presented her Treasurer's report, showing Income and Expenditure, including grant funds. TREAT has healthy balances in its General Account and the Environmental Benefit Fund. Angela McCaffrey gave an overview of TREAT's activities for the year in her President's report, thanking all who contributed to another productive year.

After presentation of the reports, the election of office bearers for the next year was conducted by John Hardman. Eleven of the twelve positions were filled, and as no further nominations were received, the nominees were duly elected. The Management Committee for the coming year is as follows:

Ingrid Clark did not seek re-election for health reasons and Andrew Brooks has now joined the committee, but otherwise all positions remain the same.

Angela chaired a General Meeting which always follows the AGM, and there were no matters raised. She then welcomed our guest speaker John Clarkson who gave an interesting and lively presentation on the botanical naming of plants. See his 'Scientific Names' notes in this newsletter.

Following many questions, supper was held and the evening concluded about 9.30pm.

President's Report AGM 2019

Angela McCaffrey

Up until this last week, it's been a really good year for TREAT. In February we signed a new Memorandum of Understanding with QPWS, ensuring the future of the nursery for at least another 5 years, and a new infrastructure program took place providing the nursery with improved water supply and purification, new gravel paths, fencing, additional hardening bays, a new concrete floor and a new coat of paint, making the place look good and perform really well. TREAT contributed with a hot water tank for the kitchen to make washing the cups every Friday less of a chore.

Production in the nursery has continued apace to produce tens of thousands of strong healthy trees, thanks to the QPWS staff including Ranger in Charge Nick Stevens, Peter Snodgrass, Simon Brown, Stuart Russell and recent addition, Mick Sexton. Volunteer numbers on Friday mornings are regularly over 40 making it a real joy to be amongst such a vibrant crowd.

Wet season plantings this year comprised of 11 events, mostly on Saturdays but one at Massey Creek on a Thursday and one at Michael Hoare's on a Friday. TREAT's own project site shifted focus to the Lakes Corridor, between Lake Barrine and Lake Eacham, where we planted 4,400 trees at 2 plantings on 1.3 ha on McLean Ridge. This was funded by a generous donation from Don Crawford. Similar plantings will take place on the adjacent site over the next two seasons, strengthening the link between the two lakes for a range of rainforest species including cassowaries. Over the whole season we planted 21,000 trees of which 10,000 came from the QPWS/TREAT nursery. A total attendance of 558 people volunteered at these events either to plant trees or prepare the BBQ. An additional 1,940 trees were given to Barron Catchment Care to support their funded projects, 3,030 went to QPWS projects and 7,275 went to members' projects. Volunteers also assisted with putting on frost guards and irrigation at the McLean Ridge site.

We held three, well attended, workshops this year. The tree identification and propagation workshop run by Peter Snodgrass and Dinah Hansman, the planting and maintenance workshop run by Mark McCaffrey and Peter Snodgrass and the fungi workshop for the field guide launch, run by the Queensland Mycological Society. Catering for these events was provided by Barbara Lanskey, Trish Forsyth and myself. We held one fabulous field day at Paul and Roberta Michna's property at Topaz where the catering was again provided by Barbara Lanskey along with our hosts.

The quarterly newsletter continues to be a fascinating read thanks to our editor, Barbara Lanskey as well as our electronic newsletter coordinators, Mandy Bormolini and Irene Gorman. Simon Burchill keeps our website up to date including adding the newsletters. Thanks Simon.

The Display Centre gets few visitors but continued to be staffed Mondays and Wednesdays throughout the year by Bob Morrison, Ingrid Clark, Linda Joncour and others.

We have held market stalls at Yungaburra Markets thanks to Shirley Prout, Trish and Andrew Forsyth and other volunteers.

John Hardman has coordinated our members' tree applications and the loan of the augers. Dinah Hansman has taken care of any media coverage including in local newspapers.

Dave Skelton continues to look after our data base with its ever increasing mountain of information, and also assisted Cath Moran on our Carbon Project to determine and document how easy/difficult it is to get a financial return from storing carbon in biodiverse plantings. Cath's report is the subject of an article in the latest newsletter.

Huge thanks go to the whole committee for their dedication and input but especially to secretary, Doug Burchill and treasurer, Mandy Bormolini. I feel so privileged to be a part of such a dynamic and hard working community group.

Lastly, I just want to reflect on the events of last weekend when low-lifes decided to take around $30,000 worth of TREAT's equipment from Ian's shed at Freemans Forest NR. It's easy to get despondent when such things happen but the generosity of good people soon restores faith in humanity. We have already received promises of replacements for the market gazebo, folding tables and the all important BBQ. Thank you to those contributing and also to Doug for dealing with the police and improving security at a time when, for various reasons, I could not.

Sorry if I've missed anyone; your contributions are always gratefully received. I look forward to the next 12 months.

Scientific Names

John Clarkson

The system we use today for scientific names dates from 1753. It was developed by a Swedish botanist Carl Linnaeus (1707-1778).

Many people are reluctant to use scientific names but they are sometimes unaware that they do, e.g. Chrysanthemum.

Some facts about scientific names

There are no rules for how plant names are formed. They can be drawn from all manner of sources.

Regardless of their origin, names are treated as Latin. Hence they have gender, number and case. This explains why the endings of specific names differ between genera.

Basic canon of botanical nomenclature:

Application of names is governed by an internationally accepted set of rules, The International Code of Botanical Nomenclature. These rules are considered at each International Botanical Congress held every 6 years. The latest was held in Shenzhen in China in 2017 and the Code published the following year.

Botanical names consist of two parts (a binomial). The first is the genus written with an initial capital letter. The second part is the species name or specific epithet written entirely in lower case. This is easy to conceptualise if you think of the genus as a noun and the specific epithet as an adjective. Hence you have brown horses and black horses, brown cows and black cows. Cows is a collective term and the colour identifies which horse or cow.

Named for someone

This could be the person who discovered the plant, some noteworthy person, a patron, friend, lover, wife, husband or partner.

These names are recognised by ending in '-ii' if the person is a man or '-iae' if the person is a woman. The first 'i' is dropped if the name ends in 'er'. There are other fiddly rules for names ending in vowels and names which are considered to have Latin roots, which see the first 'i' dropped. I won't go into these as they would only complicate matters.

For example, Miliusa traceyi, a tree from several rainforest types on Cape York Peninsula, is named for Geoff Tracey. Argophyllum verae is named for Vera Scarth Johnson.

The epithet can commemorate more than one person. When this is the case the name will end in '-iorum' or '-iarum'. Again the 'i' is sometimes omitted. Cupaniopsis cooperorum is named for both Bill and Wendy Cooper.

People can be commemorated in generic names; e.g. Banksia is named for Sir Joseph Banks. The recently erected genus Gossia for some plants which were once known as Austromyrtus, is named for Wayne Goss, a former Queensland premier. The genus can combine both the first and second name as in Lenbrassia which was named for Len Brass, a Toowoomba born botanist noted for his work in many tropical parts of the world.

Named for some descriptive feature of the plant.

These usually have Latin or Greek roots. Xanthostemon chrysanthus, the attractive yellow-flowered tree which is growing in the median strip on the Captain Cook Highway opposite Cairns Airport, gets its name from the Greek 'xantho-' meaning yellow and '-stemon' stamen, the male parts of the flower, and 'chrysanthus' another Greek word meaning golden-flowered. Eucalyptus grandis, flooded gum or rose gum, gets its name from the Latin adjective 'grandis' which means large, great, big, tall or lofty, all perfect descriptions of this gum tree.

Named for some geographic feature

This could indicate the country of origin, e.g. 'australiensis' coming from Australia, (don't confuse with 'australis' which means southern) or 'novoguineensis' from New Guinea. Notice these all end in '-ensis' the Latin suffix indicating a country or place of origin.

The name could indicate something about the place the plant commonly inhabits, e.g. 'monticola' the Latin ending '-cola' meaning '-dweller', hence a mountain dweller. Another way this could be done would be to use the ending '-arius' indicating a connection, hence 'arenarius' pertaining to sand.

Modify an existing name

This is commonly used for generic names where a prefix such as 'neo-', meaning new, or 'pseudo-', false, is added to an existing name, hence Neolitsea from Litsea and Pseudopogonatherum from Pogonatherum. Alternatively a suffix can be used e.g. '-astrum' to Malva to form Malvastrum indicating an incomplete likeness.

Compounding names

Forming names from two or more genera is very common in orchid nomenclature where inter-generic crosses are common e.g. Epidendrum crossed with Cattleya becomes Epicattleya.


It is possible to form a purely arbitrary name by rearranging the letters of an existing name. Hence Romnalda, a grass-like plant from Mount Lewis, was coined by rearranging the letters of Lomandra, a plant which looks quite similar.

The problem with common names.

There are often many common names for the same plant and this can sometimes lead to confusion. For example, Salvation Jane and Patterson's Curse are both used for the plant Echium plantagineum. One name is used by bee keepers who see it a very useful plant, the other by sheep farmers because it poisons their stock.

The common names - cooper's wood, humbug, leather jacket, red almond, red ash, red tweedie, mountain ash, sarsaparilla, soapbush, soapwood and foam bark, are all used for the common rainforest pioneer Alphitonia excelsa. At least half of these names are also used for the other 4 species of Alphitonia found in FNQ, and Smilax, a totally unrelated plant is also called sarsaparilla.

Within limits it is possible to use the same common name for several plants, but when they are used beyond local areas, communication becomes hampered by ambiguity.

2019-20 Capital Works Project

red shed

The nursery has been successful in attracting funding for a new Capital Works project this financial year to replace the old brown shed with a larger drive-through facility, which will enable storage of nursery plant and equipment as well as nursery vehicles.

The new shed will be situated behind the current brown shed, on what used to be the original QPWS house site until the dwelling was removed in 2008. The old shed will be demolished as part of the project.

We are in the process of putting the final design and specifications together and aim to commence construction in March 2020.
