Marram Grass and Sea Spurge are common weeds along the Surf Coast, although ANGAIR routinely removes Sea Spurge between Point Roadknight and Urquhart Bluff. There are two forms of Broom that have been declared environmental weeds in the Surf Coast Shire and are also Weeds of National Significance. Rather than give garden space to this invasive environmental weed, why not replace it with Slender Velvet-bush Lasiopetalum baueri, or Hazel Pomaderris Pomaderris aspera. However, if you are reluctant to dig them out, cut them down and/or spray them with herbicide, then it is essential that you maintain them responsibly. The Edna Bowman Flora Reserve has also been invaded by many exotic grass weeds, particularly Quaking Grass Briza maxima, and we are unsure how to control them. The aim of the project is to remove Bluebell Creeper from an area of Aireys Inlet where Pterostylis revoluta Autumn Greenhood and Diuris sulphurea Tiger Orchid grow.
It produces large quantities of seed, but it has low seed viability, that only last for one year in the soil. Kohuhu, Pittosporum tenuifolium, is a densely foliaged, evergreen tree or shrub to 8m high.
Seed production from Sallow Wattle is very prolific, with several hundred seeds per square metre of soil, and the seeds remaining viable for up to a decade. If seeds are beginning to form, cut off the flower heads and “cook” them in the sun inside black plastic bags before disposing of them. Burke’s backyard Internet site states “that if you want a plant that will laugh at the drought consider the humble Gazania”. Small infestations can be dug out when the soils are moist; otherwise rhizomes are likely to fragment. 2. The sticky seeds are favoured by currawongs, silvereyes and blackbirds, which disperse seeds into new areas.
A new major threat has arrived on the Surf Coast in the last three years; originating in South Africa, it is called the African Weed Orchid. It is in plague proportions in Anglesea and Aireys Inlet, and along the Great Ocean Road. Sparaxis (commonly known as Harlequin Flowers) have conspicuous flowers consisting of six petals which can be any colour ranging from cream to purple and through the full colour pallet of reds and oranges. It is spreading rapidly along Victoria’s coast, and into the Great Otway National Park, smothering and destroying indigenous vegetation. This weed has invaded the sand dunes at Main Beach, Anglesea, and is a major problem.
Since the berries are such a popular food for birds and animals, the seed in their droppings are scattered far and wide.
The shape of the phyllode is very important in the identification. Environmental Weeds –A Field Guide for SE Australia Reprinted 2003 by Bloomings Books, 3.
The leaves are fine, crowded and dark green, while the bell shaped flowers are white, sometimes tinged with pink.
Gazania is a tufted perennial growing to 30 cm high. Seed production from Sallow Wattle is very prolific, with several hundred seeds per square metre of soil, and the seeds remain viable for up to a decade. These are dense in some gardens and nature strips, and unfortunately also growing in nearby clifftops and bushland. If the plant is flowering or seeding, cut and bag the flower heads before any other treatment, or alternatively, if you are unable to spray, remove the flower heads as an interim measure. The large seed pods are green at first, but mature to dark brown, after which they split open to reveal large black seeds, which are spread by birds, particularly, but also by water, garden mulch and contaminated soil.
To control infestations, individual plants need to be dug out when the soil is moist, care being taken to avoid any corms or bulbils escaping.
The terrace containing Sea Wheat-grass that has formed at Anglesea Main Beach near the fence line, is similar to a photograph in the report showing Sea Wheat-grass on a terrace at Barwon Heads beach. Bridal Creeper was introduced from South Africa as a garden plant by at least 1857, when it was first recorded in a nursery catalogue, and in 1997 it was still sold for hanging baskets in commercial nurseries. R.G. These include native trees such as Silky Hakea Hakea sericea, Sweet Hakea Hakea drupacra, Pincushion Hakea Hakea laurina, Bushy Yate Eucalyptus lehmanni, Sugar Gums Eucalyptus cladocalyx, Sallow Wattle Acacia elata and Flinders Range Wattle Acacia iteaphylla. Vetensk. It is an erect shrub, or small tree, to 10 m high, and 10 m wide, and bears dense, yellow, cylindrical spikes in late winter and spring.
Early treatment is the best method of eradication, as small plants can be pulled out quite easily when the soil is moist.
Gorse is providing protection to young rainforest seedlings, such as Beech and Podocarp trees from the harsh wintery conditions, but soon dies once it is shaded by the rainforest plants. Dolichos Pea is very tolerant of harsh dry conditions and salt laden winds that occur on the sand dunes.
Orientalis; Gazania, Gazania linearis; Wild Watsonia, Watsonia meriana ‘Bulbillifera’; Myrtle-leaf Milkwort, Polygala myrtifolia var myrtifolia and Freesia Freesia refracta. They state that decisions on coastal weed management are without adequate information, both on their impacts on ecosystems, and on the ability of the ecosystem to respond to weed removal.
Each plant has at least two corms, one below the other, thus requiring deep digging to remove them. A. scandens prefers moister sites, and is more tolerant of shade than Bridal Creeper. I think I spent the next decade trying to get rid of it.
Spanish Heath is a member of the heath family, and is closely allied to the Australian heath family, Epacridaceae, which includes our common heath Epacris impressa.
However, most infestations I have seen in the district have been under a metre high. Two major reference books on serious environmental weeds, which I routinely use, do not even list Sea Wheat-grass (Blood, 2003; Muyt, 2001). It has rough, grey fibrous bark, distinctive branching and dense foliage.
The authors state there is a concern that volunteers are relied upon too heavily for assistance in management, and a fear that volunteers may become burnt out. Although it is not widespread at sites along the Surf Coast, it is important to control any plants you find on the coastal reserves as it will soon cover large areas. It flowers in late autumn and winter, with greenish yellow petals. Suitable replacements for the garden could include Acacia mearnsii or Acacia pycnantha, both of which should be available from local indigenous nurseries.Refer to: Environmental Weeds: Invaders of our Surf Coast-page 20, 2007 edition. Taxonomic status: Accepted. var addybe05db4c4ae2738722b042935ca1f32d = 'plant.protection' + '@'; One plant grows up to 60 tiny flowers in a dense spike that resembles a brownish asparagus spear. It is in plague proportions in parts of urban Anglesea and Aireys Inlet. var prefix = 'ma' + 'il' + 'to';
(See Flora of Victoria Vol 3, page 642, in our Library). Refer to Environmental weeds: invaders of our Surf Coast 2nd ed. ANGAIR members Roger Ganly, Margaret MacDonald and Janet Stephens, have recently started a collaborative project with the Surf Coast Shire, and Conservation and Management students from Gordon Institute of TAFE, Geelong, to tackle an outbreak of Bluebell Creeper in Aireys Inlet. My 95-year-old father can remember forests of African Boxthorn growing in West Footscray in the 1920s and 1930s. Within the Surf Coast Shire, there are some differences in the top 20 weeds listed in different sections of the Shire. 21: 211 (1800) APNI . Es una orquídea con flores pequeñas, pertenecientes a la subtribu Disinae. If this is not possible then spraying the foliage with a herbicide can be effective. It flowers in a dense panicle 25–100 cm long, white to yellowish in appearance, from January to March.
Anyone in Victoria, who finds plants that they suspect have been infected with Myrtle Rust, should immediately notify the Department of Primary Industry, calling 1800 084881 or by email to This email address is being protected from spambots.
, Disa bracteata fue descrita por Peter Olof Swartz y publicado en Kongl.
Of the 83 recognised Leptospermum species growing in Australia, four species only are indigenous to the local area.
It originated in South Africa, and was originally planted as a hedge in farmland and private gardens in Victoria in the 1800s.
Gazania produces abundant wind -blown seed and spreads rapidly, withstands salt laden winds and grows well in sandy soils.
Sweet Pittosporum has now developed into a serious invasive weed tree.
Because of its prolific seeding, it will be a very difficult plant to eradicate from our dunes, and it will readily replace the indigenous vegetation. The fungus produces lesions on soft, actively growing leaves, shoot tips, young stems, flowering buds and fruit. Silvereyes, Red Wattlebirds, Singing Honeyeaters and Spiny-cheeked Honeyeaters are known to eat its fruit. The flowers are distinctive because in almost all cases the centre of the petals is of a different colour, often bright yellow and/or dark brown-black.
Asparagus is in the Liliaceae family, and has white-pink, six petalled flowers from August to October, with globular, orange to red berries when ripe. Hakea species tend to rapidly invade the environment, especially in coastal situations. Bush invaders of south-east Australia: a guide to the identification and control of environmental weeds in south-east Australia. Sallow Wattle can fix nitrogen, and so increase soil fertility, which may affect the growth of indigenous plants that prefer low fertility soils. Reference: MacDonald, Margaret (ed), 2007 reprint, Environmental Weeds, Invaders of our Surf Coast, page 32, Surf Coast Shire/ANGAIR Inc. Wild Gladiolus Gladiolus undulate; Large-flower Gladiolus, Gladiolus tristis. In some areas on the eastern side of Port Phillip Bay, Bridal Creeper completely smothers all the coastal vegetation. It can be a large evergreen shrub 1.5m to 3m tall. Sallow Wattle is arguably the worst environmental weed along the Surf Coast. , Se encuentra en la región más austral de Sudáfrica, en áreas de perturbación leve y en Australia, como una mala hierba invasiva reciente en alturas desde el nivel del mar hasta los 2000 metros.
Flowers are yellow-green in small clusters in winter to early spring. The Australian native plant Bluebell Creeper has become a major environmental weed problem along the Surf Coast.
The phyllodes (leaf) are 5–20 cm long and 0.5–1.5 cm wide. Coast Tea-tree is a large shrub or small tree to 5 m tall. Spraying the foliage with a selective or non-selective herbicide during the cooler months, when growth is active, is another effective control measure. Dispose of the plants by sealing them in a black plastic bag and leave them to cook in the sun. sophorae.
