TREAT Newsletter Wet Season January - March 2008


Barb Lanskey

We have a big schedule of planting dates this year. There is a planting every week-end except for Australia Day and Easter. It is good to see some large private plantings and landowners generally seem to be recovering from Cyclone Larry (March 2006) and planting trees again.

TREAT was able to secure funding assistance from the Australian Government's NHT Envirofund Round 9 program to extend the plantings on Williams' property along Peterson Creek. This year we will have two plantings of 2,000 trees and there will be the usual TREAT barbecue afterwards for those attending the planting. The holes will be already dug for planting the trees.

This is the 11th year TREAT has been carrying out significant plantings on properties along Peterson Creek to help control erosion and to eventually create a wildlife corridor between Lake Eacham National Park and the Curtain Fig National Park. The corridor is now about two-thirds complete. This year the plantings will link up to a large remnant on the Williams' property.

Maintenance is a big part of successful tree planting in the tropics. For the TREAT plantings along Peterson Creek quarterly maintenance is carried out for a minimum of 3 years to help the plantings compete with aggressive tropical grasses and other weeds. Envirofund grants are for a period of only 18 months which doesn't cover maintenance for 3 years. TREAT is fortunate that the regional Natural Resource Management body, Terrain NRM, has agreed to fund the remaining 18 months of maintenance required for our Peterson Creek Envirofund plantings.

QPWS have two sites for the planting season. One is the new MaMu Canopy Walk area on the Palmerston Highway. This is in the process of construction about 300 metres east of Crawford's Lookout. There is a large car park in what was formerly a pasture paddock and it is hoped to make the area attractive with lots of trees.

The second planting site is Massey Creek on the Old Palmerston Highway towards Ravenshoe. This forms part of an important forest corridor between the tablelands and the coast. TREAT has been assisting QPWS here for several years to revegetate land acquired by National Parks to widen a narrow neck at this section of the corridor.

Penny Scott obtained funding assistance from the Envirofund Round 9 program and will be planting 4,000 trees on her property "Gumtree on Gillies" at Yungaburra. Penny will be doing 2 plantings of 2,000 trees and these will widen an area already planted along Lower Peterson Creek by Yungaburra Landcare and will extend back to an existing small remnant.

Peter Tuck was also successful in obtaining funding assistance from the Envirofund Round 9 program and will be planting 4,000 trees in 2 plantings of 2,000 on his property at Mather Road, Yungaburra, opposite the Curtain Fig National Park. Peter and Trixie have already revegetated along their section of Peterson Creek, and now want to extend that planting.

These plantings along Peterson Creek will provide important extensions of the endangered Mabi Forest which once covered the area. Tree-kangaroos have been seen regularly in the Curtain Fig National Park and along Lower Peterson Creek and hopefully in coming years their habitat will be extended significantly for their numbers to increase.

Mike and Robyn Carter at Hillcrest Road, Jaggan, will also be planting 4,000 trees in 2 plantings of 2,000. This is a property next to large forest remnants and in this area many gullies have been left vegetated. Mike and Robyn are revegetating on two cleared ridgelines between vegetated gullies. They hope to link up with the gulllies in future years and extend revegetation to other parts of the property to create a corridor to the creek at the opposite end of the property.

While TREAT is not an official partner to the private plantings, we support and encourage them and TREAT members are invited to take part in the plantings. TREAT will be offering assistance with barbecues to follow the plantings.

Members' Project Plantings

The TREAT management committee has received several requests from members for trees for project plantings. These are usually for revegetating slopes or creek banks or extending existing habitat on a property. TREAT often receives follow-up letters of thanks sometimes with photographs included and these are appreciated.

If members have a project for which they require trees and they are not seeking funding assistance from government sources, they are encouraged to fill out a TREAT application form for trees for consideration by the committee. Members are advised not to take on too much work, especially if they have jobs, and a limit of 300 trees is usually enough to care for in a year. TREAT generally will inspect project sites before considering approval.


Barb Lanskey

Within its membership TREAT has a team of volunteers we call the TAP team. These are members who like to work with children in our "Tree Awareness Programs". On Tuesday morning 8th January, three of the TAP team came to the nursery to help interest about a dozen children in trees. We showed them the Display Centre, had them clean seeds from some fruit of a tree and then pot up some seedling trees. As the weather was wet we couldn't let them do any weeding of the young trees outside. Children love these hands-on activities. Dawn, our TAP leader, has prepared other activities for children involving colouring-in, word-finding, joining dots in a picture, etc., all with a tree theme. TREAT also has large floor jigsaw puzzles, a collection of rainforest and animal books and workbooks about trees for school students.

On Tuesday the group was organised by Jodie from National Parks Volunteers as part of their Kids Activities for the school holidays. TREAT welcomes any such group and each year we invite schools to participate in our TAP programs. Invitations are sent out to all local primary schools at the beginning of the year, and we usually have 3 or 4 schools interested to make TAP part of their school environment program.

For the schools we offer a visit to the nursery, a small tree planting at the school and a water quality testing program. The visit to the nursery can be for any class level. We always include a tour of the Display Centre and nursery and the activities of seed cleaning, potting and weeding, but for older students we focus on more advanced activities such as tree identification rather than colouring-in etc. Times are flexible and we fit in with the school's requirements.

If the school wants the students to do a small planting in their grounds, TREAT will inspect the site to determine which trees will be suitable. We liaise with the school about preparing the ground for the planting, when the planting is to be done and advise how the trees should be cared for afterwards. TREAT helps with the planting and supplies the trees.

The water quality testing program (called "Flowing On") is for older students as the testing involves some advanced calculations. This program starts with a visit to Lower Peterson Creek at Yungaburra. Here the students walk along the creek bank to observe the condition of the creek and then collect water samples under supervision. These samples are taken back to the nursery where TREAT has water testing equipment. The results obtained are compared with results from samples taken in previous years.

Some of the TAP team will be away for an extended period from March, so TREAT needs some extra volunteers. Pauline Errey joined the team this year and helped on Tuesday. If there are other volunteers who would like to be part of the team please contact either Dawn (ph 4095 1208) or Barbara (ph 4091 4468).


Kylie Freebody (Eacham Shire Community Revegetation Unit)

This winter a series of frosts on the Atherton Tablelands caused considerable tree losses in revegetated areas. The frost related tree deaths equates to an estimated loss of $ 88,000 worth of revegetation works (about 4 hectares of plantings) across the southern Atherton Tablelands. This figure includes the cost of establishing the plantings and maintaining them up to the frost events.

As noted in Geoff Onus' Frost Report1, it is suggested that this year was a one in twenty, or even a one in fifty year event. He also notes that there were up to seven frosts spread over a three week period and they affected areas from Emerald Creek near Mareeba (altitude ~ 400m) to Ravenshoe (altitude ~1000m). Many tree plantings carried out by community groups, volunteers, individual landholders, state agencies and local government suffered considerable tree losses as a result of these frosts.

QPWS, Green Corridor and the Eacham Shire Community Revegetation Unit have individually assessed tree mortality rates from frost in young plantings. Observations have also been recorded about the various factors that may influence the tree mortality rate.

The young plantings (less than 5 years old) experienced different percentages of tree mortality, ranging from very few tree deaths (less than 10%) to extremely high numbers of deaths (92%). Even some plantings greater than 5 years of age lost trees of considerable size, most notably were species such as Blue Quandong, Elaeocarpus grandis, Bleeding Hearts, Homolanthus novo-guineensis Candlenut, Aleurites rockinghamensis. It is believed that one of the major factors affecting a tree's lack of resistance to frost damage is its wood density (personal communication Tim Curren, School for Field Studies). That is, generally speaking, the quicker growing species with a lower wood density will be more susceptible to frost damage.

Factors that appear to affect the frost resistance of an individual tree include; age, vigour, and its wood density (as mentioned earlier). The revegetation projects that were planted late in the wet season (2-4 months prior to the frost events) generally suffered the highest mortality rates. However, one 16 month old planting that is positioned very low in the landscape suffered an 82% mortality rate. There are also lots of site specific factors that will affect the frost resistance of an individual tree or a planting. For example cover provided by an isolated remnant tree may protect numerous small trees that are planted adjacent to it.

Tree planters now face the dilemma of replanting these frosted areas at an estimated cost of approximately $52,000 to reinstate the affected 4 hectares. This figure does not include an additional $52,000 that will be required to maintain these plantings and get them back to the level of establishment they were prior to the 2007 frosts.

In summary, it appears that the frosts over the 2007 winter period resulted in a loss of $88,000 worth of revegetation works and the estimated cost required to replant and maintain these areas back to their pre-frost level of establishment is an additional $104,000. I am sure most keen tree planters out there will be hoping for a much milder winter next year!

Frost Tolerance at Peterson Creek

Barb Lanskey and Peter Snodgrass

In the last newsletter Peter Snodgrass mentioned in Nursery News that various tree species were recovering from frost damage at Peterson Creek.

For the planting done in February 2007 at the Williams' site, Peter has compiled a list of the species found to be most tolerant, moderately tolerant and least tolerant.

The most tolerant species showed very little or no sign of frost damage. These were:

The moderately tolerant species showed some signs of frost damage and some lost all their leaves but were re-shooting within a week or two.

The least tolerant species were totally defoliated and most had at least 90% of their stems totally frozen which resulted in re-shooting from the very base of the tree. For some this was still too much of a shock and they died shortly afterwards regardless of conditions.

When TREAT planted the adjacent area in October (with funding assistance from Terrain NRM), we could see how many of the trees were coming back. There was some follow-up watering of the site in the dry period following the frosts and this may have helped some species survive. In December when TREAT fertilised the trees as part of quarterly maintenence, we saw good growth on all those that hadn't died. The Bleeding Hearts were very obvious, looking quite lush with several stems growing from their base.

Where appropriate, TREAT will be doing infill planting to replace some of the losses and this may be as part of this year's plantings.

Frost and Mulching

Bronwyn Robertson / Peter Stanton

In Geoff Onus' article in the last TREAT newsletter, he outlined several factors which can assist in the establishment of young seedlings. One of these was the use of mulch to help suppress weeds and maintain soil moisture. Peter Stanton has kindly provided further information relating to the effect of mulch in frost-prone areas, as detailed below.

"Early in my career in forestry I worked in forestry plantations in the Brisbane Valley, where frost was a major hazard for young trees. I did a lot of research on how to predict where the most severe frosts would occur. One of the things I noticed early was that trees on bare red soil survived best; those growing in grass or where there was heavy mulch fared the worst. Soil colour was an important factor, with black soils being the coldest, but irrespective of that, on any soil mulched trees were the least likely to survive. I was able to show that the surface of the mulch during the worst frost events could be 2-3 degrees colder than the surface of bare soil.

The reason for this can be found in the science of physics. On a clear still night most heat loss from the surface of the soil is by radiation to the sky. Heat lost in this way is replaced from deeper in the soil profile by conduction to the surface. Mulch interrupts this process; heat is still lost by radiation from the surface of the mulch, but as mulch is a very poor conductor it is not replaced. Effectively the mulch provides an insulating blanket which prevents heat transfer from the soil to the mulch surface.

Another point that should be recognised is that the amount of heat lost by radiation from any point on the soil surface is governed by the amount of sky visible from that point. Thus trees near a forest edge are much safer than trees well out in the open. One of the forestry practices that utilised this knowledge was to plant fast growing frost resistant trees, usually Eucalyptus grandis, alongside hoop pine seedlings which were slower growing and frost intolerant. This put a protective cover between the hoop pine and the sky. When the hoop pine had grown sufficiently on site, the Eucalypts were removed. A high level of protection of rainforest plantings in frost areas could be achieved by planting E. grandis first at, say, 3-4 metre spacings."


Nick Stevens

Well another wet season is with us, and as I sit here waiting for the next thunderstorm to break the sweltering heat, I look out the window and it appears to be snowing. No, the heat hasn't had that much effect - yet. I'm really watching the drifts of plumed seeds of Parsonsia straminea or Common Silkpod vine dispersing on the monsoon breeze from high in the forest canopy as their ripe fruits split in the heat.

Parsonsia straminea belongs to the large family Apocynaceae (includes Milky pine, Cerbera, Hoya vines and many other local species) and is one of 35 Australian species in the genus Parsonsia. These vines are food plants for a number of local butterfly species.

Another well known aspect of the monsoon is lightning. While the light shows can be spectacular and the associated rain is most welcome at this time of the year, a direct hit from lightning wrought havoc at the nursery in early December. It struck a section of galvanised pipe in the QPWS water supply line, damaging the pipe itself, UV water filters, nursery irrigation controllers, hot water systems and telephone systems at both the nursery facility and the Lake Eacham office and workshop. It took staff nearly 2 days to locate and fix the damaged pipeline and the phone systems and irrigation controllers had to be completely replaced.

In late November Senior Ranger Michael Overland, Lake Eacham Management Unit staff and nursery staff commenced planting to assist in the rehabilitation of the newly developed Lake Eacham car park. This planting was followed up a week later by a larger planting with TREAT volunteers assisting, planting and mulching close to 500 trees. These early plantings are establishing well with next to no losses and will be followed up with some smaller plantings during the wet season. Many thanks to all who assisted.

QPWS has a number of plantings coming up this season on the National Park estate. Among them are Massey Ck section of Tully Gorge National Park, the car park development and boardwalk walking track at the MaMu Canopy Walk - Palmerston section Wooroonooran National Park, Eubenangee Swamp National Park, Mossman Gorge National Park and possibly continuing with roadside plantings in the Lake Barrine section of the Crater Lakes National Park. TREAT's assistance will be sought and greatly appreciated for the plantings at Massey Ck, MaMu Canopy Walk carpark and the possible Lake Barrine project.

Staff at the nursery until the end of January will remain as Nick Stevens, Darren Caulfield and Kevin Mackay. Peter Snodgrass is taking some well deserved leave and Nick Teiwsen is on secondment completing Cyclone Larry cleanup work on walking trails in the Misty Mountains network. Darren and Kev are are filling Peter and Nick's positions respectively.

Bat Rescue at Lakeside

Barb Lanskey

This has been the worst tick paralysis season on record for the Tolga Bat Hospital. Jenny Maclean and her volunteers have rescued over 500 baby Spectacled Flying Foxes from a revegetation site at Lakeside, Yungaburra. The colony usually resides in the Tolga Scrub and this is why Jenny has the word Tolga in "Tolga Bat Hospital" even though she's located on the Herberton side of Atherton. Last baby season there were a few bats at Lakeside, but this baby season the majority of the colony decided to move there. When I went there in December with Helen Adams to look for bats in distress I was amazed at the forest structure the site had attained. Last year the bats had generally moved on by April and this year Jenny is planning some clean-up work there after they move on again. Jenny stresses the importance of controlling Wild Tobacco bush (Solanum mauritianum) as research indicates that bats are more prone to tick paralysis when they come closer to the ground to feed on the fruits of Wild Tobacco. TREAT may hold a field day at the Lakeside site in May/ June.

Jenny again asked for some assistance from TREAT members to provide some pre-cooked meals to save exhausted volunteers at the hospital having to cook at the end of the day. Several members responded and their efforts made a big difference to morale at the hospital at the busiest time. When I visited before Christmas the hospital was caring for 320 orphans, 50 bubs with mums and 20 adults. They had already fostered 130 orphans into care at Cairns, Townsville and Brisbane. These bats will be returned to the hospital for release back into the colony. The babies are now 3-4 months old but are dependent on their mothers until they are 6 months old. Jenny will start releasing them in mid-January. Jenny would like to thank the TREAT members for their help with meals at a crucial time and says the bat hospital can now cope on its own.

While at the hospital I talked to "Lib from Lismore" who had come up to help out. Lib has rescued lots of bats at Lismore and mentioned the polypipe that landowners in her area use to cover the top strand of barbed wire on fences in "hot spots". The polypipe is split quite easily in a specially made gadget. Here, Brian Norton at Millaa Millaa is trialling the use of old electric fencing tape put about 4 inches above the top strand of barbed wire. To encourage others to use it, a drop off point is needed where farmers can leave their old tape (white) and those landowners wishing to use it can pick it up. If anyone can help with this, please contact either Jenny (ph 4091 2683) or me (4091 4468). Jenny has just sent out electronically her first Wildlife-friendly Fencing newsletter.

Cassowary Awards

In November, Cassowary Awards were given to several people with a TREAT connection.

Frederick Michna received a Young Cassowary Award. He also received the 2007 Future Leaders Environment Award in October. This year he was made a foundation member of the Queensland Youth Environmental Council 2007-2010 and is producing a position paper for the QYEC on biodiversity. He welcomes members' ideas by email at: Fred is a member of TREAT and attended our Tree Identification and Seed Propagation Workshop in 2006.

David Leech and Wally Coutts received an award for Community Conservation. David and Wally are tireless workers on Lower Peterson Creek where they have revegetated along the banks and made a community-friendly walking track from the Gillies Highway bridge at Yungaburra to Frawley's Pool and thence to the old railway bridge. At Frawley's Pool they've constructed an interpretive shelter. David is one of TREAT's original members and saw the need for working on Lower Peterson Creek, seeking advice from Geoff Tracey (one of TREAT's founders) on tree species. The walking track is dedicated to Geoff. David and his loyal band of workers now call themselves Yungaburra Landcare.

Sandy Clague received the award for Conservation. Sandy and her late husband Doug have revegetated large tracts of their property at Millaa Millaa and I well recall the trips I made there to learn about revegetation and tree species. Doug was a regular Friday morning volunteer and now that Sandy has retired she comes to TREAT when she can. Sandy is still working at revegetation on the property.

Peta and Jon Nott have been TREAT members for many years and received the Neighbour award.

Wendy Cooper received the award for Science. Those of us who invested in Wendy's book "Fruits of the Australian Tropical Rainforest" appreciate her efforts. TREAT's copy is put out for reference every Friday.

TREAT's Christmas party

We had a lovely spread for a prolonged morning tea on 21st December as our break-up party for Christmas. This year we decided against the traditional sausages barbecue, opting instead for pizzas and other fare to augment goodies that members supplied for the occasion. I brought Joan and James over from Ozcare, Helen brought Tony, John Hall and Shirley came, and other members such as Ben Constable made a special trip to say hello again. We all had a really lovely time and there was much to indulge the palate. TREAT had a holiday for Friday 28th December. but we were back to work on 4th January. Members then were busy preparing the many seeds collected during the break by the nursery staff. The nursery is bulging with trees ready for planting and as space is limited, no potting was allowed! Many members consolidated trees in the hardening bays creating a bit more space.

Ozcare visit to the nursery

Joan recommended to the Diversional Therapist at Ozcare a visit to the nursery and in November Joan and James came one morning with 3 other residents plus bus driver and therapist. Joan thought more residents might have come if she hadn't mentioned the stairs but as the bus delivered them from the top area down to the Display Centre the stairs didn't have to be negotiated. Everyone enjoyed the visit and the residents were keen to donate to TREAT's Environmental Benefit Fund for copies of Joan's book about the early years of TREAT.

Channel 10's documentary on tree-kangaroos

In July, Channel 10 spent a week on the tablelands filming for a documentary on tree-kangaroos. It was shown on TV the afternoon of the election, 24th November. I was interviewed for it at Peterson Creek as part of community involvement in regenerating habitat for tree-kangaroos and the film crew also came to TREAT on Friday. The documentary is titled "Rare Bear: The Tablelands Tree Kangaroo". I found the documentary very worthwhile viewing and TREAT received good publicity. Copies of the documentary can be obtained from Channel 10.


Milan Prochazka was a dedicated TREAT volunteer on Fridays and at plantings in recent years. He joined TREAT in the early years when he lived in Ravenshoe, but then moved south to live. When he returned he rejoined TREAT and we much appreciated his mechanical expertise as well as his regular help. Again he moved south and we received a Christmas card and letter from him. He encouraged us to keep planting and wished he could again enjoy the camaraderie and enthusiasm he found at TREAT.

Regional Ecosystems

Bronwyn Robertson

The term regional ecosystems, or REs, is used commonly when discussing conservation and vegetation management. Regional ecosystems were defined by Sattler and Williams in 1999 as vegetation communities that are consistently associated with a particular combination of geology, landform and soil in a bioregion. A bioregion is an area delineated by broad landscape patterns that reflect the major geological structure, climate patterns and broad groups of plants and animals. There are 1351 REs in Queensland and 13 bioregions.

Regional Ecosystem Numbers

Three numbers are used to describe each regional ecosystem e.g. 7.8.3. The first number refers to the bioregion the regional ecosystem is found in. There are 13 bioregions in Queensland numbered from 1-13. The Wet Tropics bioregion is number 7.

The second number refers to the land zone that the regional ecosystem occurs on. The land zone is a simplified geology/substrate-landform classification for Queensland. There are 12 different land zones. For example, land zone 8 is plains and hills on Cainozoic flood basalts.

The third number refers to the specific ecosystem. e.g. RE 7.8.3, or Mabi Forest, is described as complex semi-evergreen notophyll vine forest associated with upland areas on basalt in the Wet Tropics.

The Queensland Herbarium is now the lead agency for vegetation surveying and mapping in Queensland and has established an internationally recognised methodology. They produce regional ecosystem maps for the majority of Queensland at a scale of 1:100 000. Their two major mapping products are maps of pre-clearing and current remnant regional ecosystems and vegetation. Remnant mapping is updated about every two years and is based on Landsat satellite imagery, recent aerial photography and field based ground truthing.

Pre-clearing Vegetation

Pre-clearing vegetation communities are based on 1960 aerial photos, along with any available land system, geology, soils, other land resource mapping and early surveyor's records. 1960 aerial photos are used because they are the earliest uniform state-wide coverage. There is also extensive field sampling, ground truthing and data collection to produce the maps.

Remnant Vegetation

Vegetation is defined as remnant if the tallest vegetation layer is at least 70% of the height and has 50% of the cover of the normal height and cover for that layer. It must also be comprised of species characteristic of the vegetation's undisturbed predominant canopy. It may include vegetation which has been cleared or disturbed in the past but which now meets the above criteria. It also includes many areas which are more or less undisturbed and areas protected in reserves.

Non-remnant vegetation is all vegetation not mapped as remnant. This may include young regrowth, heavily thinned or logged and significantly disturbed vegetation that fails to meet the structural and/or floristic characteristics of remnant vegetation. It also includes urban and cropping land. Areas of non-remnant vegetation may still retain significant biodiversity values.


The RE classification system is used in several different pieces of legislation, including the Vegetation Management Act 1999, the Environmental Protection Act 1994 and the Environment Protection and Biodiversity Conservation Act 1999.

Classification of Regional Ecosystems


Regional ecosystems are listed as endangered under the Vegetation Management Act 1999 if there is less than 10% of its pre-clearing extent remaining across the bioregion, or 10-30% of its pre-clearing extent remains but the remnant vegetation is less than 10 000 hectares. On regional ecosystem maps, this category is coloured light or dark pink.

Of Concern

A regional ecosystem is listed as of concern under the Vegetation Management Act 1999 if there is 10-30% of its pre-clearing extent across the bioregion, or if more than 30% of its pre-clearing extent remains but the remnant extent is less than 10,000 hectares. Of concern regional ecosystems are shown as light or dark orange on maps.

Not of Concern - No Concern at Present

Under the Vegetation Management Act 1999, regional ecosystems listed in this category have over 30% of their pre-clearing extent remaining and the remnant area is greater than 10,000 hectares. Green represents this category on regional ecosystem maps.

White areas on regional ecosystem maps signify areas where no remnant vegetation has been recorded. It may include cleared areas, regrowth and other non-remnant vegetation and urban areas.

Fruit Collection Diary

The collection provenances listed in the newsletter's Fruit Collection Diary are regional ecosystems. There are 3 main regional ecosystems from which fruit are collected for the nursery: "Mabi" (7.8.3), "Hypsi" (7.8.2) and the Coast (7.3.10). These are described as:
