Threatened rainforest plants of the Gold Coast2 3

IntroductionThe Gold Coast’s rainforests lie within one of Australia’s nationally recognised biodiversity hotspots – the Border Ranges of southern Queensland and northern New South Wales.

Broadly speaking, the city marks the junction of our eastern seaboard’s tropical and temperate zones, and ranges from coastal headlands to the hinterland’s cool, misty mountain tops. Our rainforests are the green behind the gold, a magnet for local and overseas tourists, bushwalkers, naturalists and people just wanting that ‘rainforest experience’. To protect and conserve our rainforests, it is helpful to know a little of their history and the great diversity of species they contain.

Rainforest plants have their evolutionary origins in the vast, temperate rainforests of Gondwana, the ancient southern supercontinent. We have learnt a great deal about plant origins and evolution, geological processes and climate change by studying existing species and fossil records. For millions of years after Australia separated from the remnants of Gondwana, rainforest continued to flourish but the climate gradually became hotter, drier and more fire prone as Australia drifted north. Eucalypts and acacias evolved in response to the changing environment and became dominant over most of the continent. The rainforests retreated to refugia, like wetter coastal areas and mountain ranges, where they were protected from drought and fire.

In the Pleistocene period (1.6 million – 10,000 years ago), rainforest periodically expanded and contracted in response

to the warmer, wetter conditions of the interglacial periods and the increased aridity of the glacial periods. The most recent glacial period ended about 11,000 years ago and rainforests began to expand once more. During this latest period of rainforest expansion indigenous people inhabited the present day Gold Coast. The ocean, rivers and forests provided them with a sustainable source of food, raw materials and medicines.

When Europeans arrived in the mid-1800s the Gold Coast was heavily forested. Timber getters were the first to reach the area and began selectively logging the more accessible forests for red cedar, beech, hoop pine and other prized timbers. Farmers and graziers arrived soon after and commenced clearing the rainforest ‘scrubs’, burning the timber where it was felled. Whilst rich in species, the lowland rainforests were the first to disappear. Little thought was given to conserving representative areas of the different forest types.

Today we have a better understanding and appreciation of our rainforests. Their evolutionary history, the great diversity of species they contain and the spectacular landscapes in which they are found have been recognised in the World Heritage declaration of the Gondwana Rainforests of Australia (1994). Now, in the Gold Coast and elsewhere, many areas cleared of rainforest in the past are being allowed to naturally regenerate or are being replanted with native rainforest species to replace some of what has been lost.

Threatened rainforest plants of the Gold Coast4 5

Common rainforest types of the Gold CoastDifferent types of rainforest exist within the Gold Coast, often in close proximity to each other and interspersed amongst non-rainforest vegetation types e.g. eucalypt forest.

Subtropical rainforest

• is widespread throughout the hinterland from the coast to the ranges

• is often found in patches and strips in sheltered gullies and on protected, south facing slopes

• exists where rainfall is high (greater than 1300mm annually) and temperatures warm (typically below about 600m elevation)

• has vegetation that appears luxuriant, fitting the common impression of rainforest, with high species diversity and many plant forms including tall trees, strangler figs, palms, vines, epiphytes and ferns.

Riparian (gallery/riverine) rainforest

• is found in narrow strips along watercourses, sometimes with Eucalypt species and Brush Box (Lophostemon confertus)

• typically has foliage that overhangs the water and trees that must withstand occasional flooding

• has been highly impacted by clearing; what remains is often threatened by weed invasion and fire.

Dry rainforest

• typically survives in very small patches, which have escaped clearing and have some natural protection from fire e.g. rocky outcrops

• is found in parts of the city with lower rainfall (less than 1100mm annually)

• is much less luxuriant than sub-tropical rainforest, with a lower canopy (though there may be scattered tall emergent trees like Hoop Pine (Araucaria cunninghamii) and Crow’s Ash (Flindersia australis) and fewer vines and epiphytes

• comprises trees with smaller leaves than those of sub-tropical rainforest; the leaves, stems and branches of dry rainforest trees sometimes have prickles.

Wet sclerophyll (eucalypt)

• is an intermediary type of forest rather than true rainforest

• is characterised by eucalypts in the canopy and rainforest plants in the understorey

• may evolve to have a canopy dominated by rainforest trees, rather than eucalypts, in forests where fire is excluded entirely.

Threatened rainforest plants of the Gold Coast6 7

Uncommon rainforest types of the Gold Coast

Warm temperate rainforest

• is found in areas of intermediate elevation, cooler temperature and typically less fertile soils than sub-tropical rainforest e.g. Springbrook and Lamington plateaus

• has less diversity of plant forms and species than subtropical rainforest

• is often dominated by the tree species Coachwood (Ceratopetalum apetalum) and Sassafras (Doryphora sassafras)

• often has various lichens covering the tree trunks.

Cool temperate rainforest

• is restricted to the highest parts (above 900m elevation) of the Springbrook and Lamington plateaus, and is only found within National Parks

• is found in areas with very high annual rainfall (1500–3500mm)

• is typically dominated by Antarctic Beech (Nothofagus moorei)

• has an abundant representation of ferns, mosses, orchids and lichens.

Littoral rainforest

• is found close to the sea on nutrient rich sandy or basalt volcanic soils

• remain on sandy soils in only a few tiny fragments in Surfers Paradise

• remain on basalt volcanic soils in Burleigh Head National Park

• has a wind-sheared upper tree canopy with species tolerant of some salt spray, such as Tuckeroo (Cupaniopsis anacardioides) and Cheese Tree (Glochidion ferdinandi).

Paddock trees

Surrounded by paddocks, isolated and clearly subject to a range of threats including grazing, weeds and fire, these trees may not seem significant. However, such trees can be very significant as either a threatened species themselves, or by providing the right conditions (e.g. shade and protection) for other threatened rainforest species to establish. Paddock trees also act as important habitat in fragmented areas and as stepping stones to larger patches of rainforest.

Threatened rainforest plants of the Gold Coast8 9

Threats to rainforestMany rainforest plants struggle to survive in small, isolated patches, where they are particularly vulnerable to various forms of disturbance and inbreeding. The threats listed here will be applicable, in various combinations, to most of the species described in this booklet.

Weeds

In the same way our city supports a great diversity of native species with its wide variety of soil types and altitudinal conditions, it also supports a huge array of introduced species. Weeds can be an insidious threat not readily apparent to a casual observer who may not recognise them as weeds or understand their capacity to damage an ecosystem. Some weeds are so destructive they have been termed ‘transformer weeds’, because they transform an area’s landscape, and weeds are considered one of the biggest threats to our city’s biodiversity.

The great news is that we can all play a role in the control and reduction of weeds. First and foremost, avoid interfering with the canopy, understorey or groundcover of intact, native forests. If you open up the canopy by cutting down trees, or clear out your understorey, you will let in more light and disturb the soil, creating the very conditions in which weeds thrive.

Secondly, obtain a copy of the City’s free Environmental Weeds of the Gold Coast booklet so you can get to know the common weeds, look out for them and share your knowledge with friends and neighbours. Research plants before you introduce them to your property and guard against inadvertent introduction or spread of weeds on vehicles, clothing, livestock and machinery.

Thirdly, when you identify weeds on your property, get in there and get rid of them. There’s often a great native seed stock in the soil below, eager to establish and transform your property from a weedy mess to bushland paradise. The City understands such a task can be overwhelming and that you may not have the knowledge, skills or confidence to undertake such an effort. That’s why we created the Conservation Partnerships Program, which provides advice and support to landholders wanting to restore their property’s native habitat.

YOUR PROPERTYDoes your property have a patch of rainforest ‘down the gully’ or ‘up the back’?

Rainforest patches, no matter how small or disturbed, can be a treasure trove of threatened species. However, the ongoing survival of these species is at risk if property owners are not aware of their significance and/or do not take action to protect them. With the help of this booklet, we encourage you to investigate the special plants on your property, learn how to recognise and deal with threats to rainforest and, where necessary, start restoring your property’s rainforest back to its former healthy state.

Climate Change

Changes in temperature and rainfall can have significant effects on our city’s rainforest species. For example, without consistent rain our rainforests will become drier, potentially resulting in higher fire frequency and/or intensity, which rainforest plants can’t tolerate. Drier conditions can also leave gully rainforest species prone to death and our gullies consequently susceptible to erosion. Mountain-top species are particularly vulnerable as conditions warm because they’re unable to migrate to cooler altitudes and are often dependent on cloud moisture created under the right conditions on mountains. Warmer conditions may also provide the right habitat for a greater variety of weeds. It’s crucial we reduce threats, such as weeds, now to build more resilience in our rainforest systems so they may better cope with the changing climate.

Clearing

Native vegetation (including rainforest) is protected by Federal, State and local legislation. However, with increasing population growth in the region, Southeast Queensland is experiencing large amounts of vegetation clearing, particularly in areas designated for urban development. This highlights the important role private landholders play in restoring native habitat and protecting our threatened species. The City’s Conservation Partnerships Program provides advice and support to landholders who want to reduce their property’s threats and restore native habitat.

Fire

Unlike eucalypt forest, where species have developed strategies to survive (and even depend on) fire for regeneration, rainforests can be damaged or destroyed by fire. Therefore, rainforests should not be deliberately burnt and, where possible, be protected from fire spreading from adjoining areas.

Grazing

Grazing animals like cattle, horses and goats can trample or eat rainforest seedlings and compact soil, preventing natural regeneration. Fencing rainforest patches off from these animals can provide a solution. You can get advice on wildlife friendly fencing, revegetation and weed management from the City’s Conservation Partnerships team.

Collecting

Unethical and illegal collection of plant specimens in the wild poses a serious threat to some species. Native plants should be purchased from an accredited and reputable nursery.

Rainforest restorationMost small patches of rainforest on the Gold Coast have experienced some level of disturbance and require some restoration work. Restoration often involves weed control and potentially some planting to restore the natural habitat. When considering a restoration project, it’s important to note that long-term commitment and careful planning is required to ensure your restoration efforts achieve the outcomes you’re seeking. Before you start, determine which area you’ll focus on, what weeds you’ll be targeting, what methods you’ll use and when you’ll do your follow up treatments. All these considerations are important to your restoration project’s long term success.

The City’s restoration teams, community groups and private landholders are fighting weeds on public and private land, and have accumulated a wealth of experience and knowledge. Advice and support on how to restore your property’s forest is readily available from the City’s Conservation Partnerships team.

City of Gold Coast assistance

The City of Gold Coast (City) recognises the valuable role private landholders play in restoring and protecting the city’s natural assets, including its threatened species. If you’re interested in restoring your property’s rainforest (or other type of native habitat), contact the City’s Conservation Partnerships team and find out whether you’re eligible for an officer to visit your property. During the visit the officer will provide you with property maps, identify your property’s

native plants and weeds, give you tips on how to control your environmental weeds and even work with you to prepare a simple restoration plan.

If your property has more than one hectare of vegetation or area you’d like to restore to native habitat, you may be eligible to register with Land for Wildlife and continue receiving ongoing advice, support and incentives. Your property may even qualify for a Voluntary Conservation Agreement, which provides financial incentives and support to achieve your restoration outcomes and protect your property’s conservation values.

The City also offers the Nature Conservation Assistance Program (NCAP) to private landholders with potentially high conservation land. NCAP delivers grant funding for on-ground ecological restoration projects that protect and enhance the Gold Coast’s natural assets.

By restoring your property’s rainforest, you’ll join the many other private landholders, community groups and restoration teams working hard across the city on private and public land to conserve our threatened species. The continuing survival of many of the threatened species described in this booklet depends on all our efforts and commitment.

Conservation status of native plants in QueenslandThe Nature Conservation Act 1992 (NCA) and Nature Conservation (Wildlife) Regulation 2006 categorise protected species – extinct in the wild, endangered, vulnerable, near threatened and least concern – based on trends in population size, health and distribution.

Endangered species are at risk of extinction due to small population size, habitat loss, threatening processes or a combination of all these. Vulnerable and near threatened species are not yet at risk of extinction but their populations may be threatened or in decline, putting their long term survival in doubt if no action is taken to protect them.

Under the NCA, endangered and vulnerable species are deemed to be ‘threatened species’. Many of the species in this booklet are also listed as threatened under federal legislation – the Environment Protection and Biodiversity Conservation Act 1999 (EPBC). There are a range of management and recovery actions being developed and enacted to ensure the ongoing survival of threatened species.

The Queensland Herbarium studies, describes and names plants, and records the floristics, structure, and distribution, and conservation status of Queensland’s plant communities.

How to use this bookletThis book has been developed to help landholders identify threatened species that may occur in rainforest on their property or local conservation area. Plants have been ordered alphabetically by scientific name and grouped by growth form i.e. shrubs and trees, vines and groundcovers. Diagrams describing the leaf type, arrangement and margin, and flower arrangement have been included for each species with a more detailed description provided below each of them. However, it’s worth noting that leaves can vary widely within a species due to the growth stage of the leaf, amount of sun/shade the particular leaf is exposed to and the altitude the plant is growing at. This is relevant to some species more than others. Therefore, the diagrams may not represent all possible leaf variations for the species. In instances where this is the case, the diagram will depict the most common adult form of the leaf, with further details of its other forms in the description below. An index of all species can be found at the back of this booklet.

Species descriptionsThe species described in this booklet have been included because they are threatened and are known or thought to occur in the Gold Coast area. Not all threatened species have been included and many additional rainforest species, though not listed as threatened, are considered to be of City-wide significance (CWS) because they are uncommon in the city. You will find a comprehensive listing of these and all other plant species recorded on the Gold Coast at goldcoastflorafauna.com.au. Descriptions and illustrations of the species listed on the website can be found in the reference material recommended at the back of this booklet.

Macadamia Nut, Queensland NutMacadamia integrifolia

FamilyProteaceae

HabitatDrier rainforest in city’s north. Often found as scattered individuals on rocky hillsides with volcanic soils e.g. Ormeau, Willow Vale and Upper Coomera. Overlaps with Macadamia tetraphylla in the southern part of its range where the two species may hybridise. While this species has been extensively cultivated, it is vulnerable in the wild.

DescriptionHabit: Small to medium tree.

Leaves: Leaves to 18cm long, are mostly in whorls of three (or sometimes opposite) and stiff, with toothed margins on juvenile leaves and entire margins on adult leaves. Petiole is 6–18mm.

Flowers: Cream flowers in spikes to 15cm, from winter to spring.

Fruit: Brown nut to 3.5cm during summer. The fruit of both M. integrifolia and M. tetraphylla is the well-known macadamia nut grown in commercial plantations. Many trees of both species have also been planted in farm yards since the time of European settlement making it difficult, at times, to tell if an individual tree in regrowth forest is wild or planted.

Macadamia Nut, Queensland NutMacadamia tetraphylla

Durobby, CoolamonSyzygium moorei

FamilyMyrtaceae

HabitatLowland subtropical rainforest. Prefers alluvial soils along creeks e.g. Currumbin and Tallebudgera Valleys, and Bonogin. Durobby is an example of a species which was possibly fairly common in the Gold Coast and northern NSW but has become threatened due to extensive clearing of its preferred habitat – lowland, riparian rainforest.

DescriptionHabit: Medium to large tree with scaly, reddish brown bark.

Leaves: Opposite large leaves to 25cm long are thick, leathery and glossy green above, and paler below.

Flowers: Flowers up to 4cm are spectacular pink or red in dense clusters on older branches.

Fruit: Large, edible white fruit up to 6cm form in clusters on the branches.

Richmond Birdwing VinePararistolochia praevenosa

FamilyAristolochiaceae

HabitatLowland subtropical rainforest throughout the Gold Coast, preferring alluvial soils (above about 600m, in places like Springbrook, it is replaced by the closely related Mountain Birdwing Vine – Pararistolochia laheyana).

DescriptionHabit: Woody, climbing vine with twining stems.

Leaves: Leaves are alternate up to 25cm with twisted petioles.

Flowers: Flowers up to 2cm long are tubular, cream or pinkish, and have a hairy, yellow throat.

Fruit: Yellow, ribbed, oblong fruit to 4cm.

Both Pararistolochia species are larval food plants of the Richmond Birdwing Butterfly – Ornithoptera richmondia. The introduced environmental weed Dutchman’s Pipe (Aristolochia elegans) is a serious threat to the butterfly as it is toxic to the larvae. Dutchman’s Pipe should not be planted. Grow the native birdwing vines instead. The Richmond Birdwing Recovery Network supports efforts to conserve the butterfly and its host plant by maintaining a database of vine locations and encouraging landholders to plant vines in suitable locations.
