Whether or not the local people doing what they can, with whatever resources restoration sector can meet such a challenge remains to and support are available, to achieve positive outcomes. be seen. I have not heard of similar opportunities in Some of these will be highlighted in this edition. other states leading to firm outcomes. For example, friends in Victoria continue to voice disappointment that During the year I’ve travelled to several states visiting large public infrastructure projects such as highway restoration sites, attending conferences and forums and duplications to Melbourne’s west, or the development of catching up with others in our field. On most occasions I Melbourne grassland reserves, both of which offer the find people still enthused and eager to progress the potential for grassland restoration at large scale and for concept of ecological restoration. Equally there are still achieving biodiversity, functional and amenity outcomes, many opinions on what approaches and techniques are have not to-date done so. thought to be most effective (and what are not), but this is fine if on-ground action is still occurring (and of course Finally, I also should also mention the mining sector as there is unlikely to ever be one best approach or method another potential candidate market for grassy for all situations). Another thing that continues to strike restoration. I was asked to present at the NSW Minerals me, is the ever-growing focus and interest on the use of Council Mine Conference in the Hunter this year on the seed production. I am convinced that unless we embrace topic of grassy woodland restoration. Many mines (of seed production approaches right across Australia, then different types) in eastern Australia are called upon to we have no chance of ever restoring our grassy rehabilitate land that once supported grassy ecosystems at the scales that we must. But as I have communities.

I also learnt while attending a recent Friends of Grasslands (FOG) forum that the ACT government is now keenly Grassy Groundcover Gazette 1 Carpet of Kidney-weed (Dichondra repens) Rod White Manager Environmental Services (VIC), In the last edition of the Grassy Gazette I talked about the appearance of Austral Trefoil - Lotus australis var.

This species was not in the original seeding mix and further to this, the site had One of the many rewarding experiences associated with been cropped for close to 50 years prior to the grassland restoration are the often-unexpected little restoration taking place (where site preparation involved gems that re-appear post-scraping and seeding.

This surprise species that emerge on site but which weren’t in species is considered rare in the Melbourne region and the restoration seeding mix. It is a reminder of the only occurs in Plains Grassland EVC’s. capacity for persistence in the soil seed or bud bank that some species exhibit, just biding their time and waiting for the opportunity to again express themselves when the time is right. A great example of this is Kidney-weed - Dichondra repens, which has reappeared without fail at all the restoration sites that I have been involved in. Dichondra means two-lumped and refers to the two-lobed ovary, and repens means creeping or stoloniferous. This reliable little herb occurs in a wide variety of vegetation communities including riparian woodland, plains grasslands, Red Gum woodlands, Coastal banksia woodlands, dry and valley sclerophyll forests and grassy lowland open forests. Blushing and Slender Bindweed - Convolvulus angustissimus ssp. angustissimus/omnigracilis, are another relatively common component of our grasslands.

Honours is an intensive research-based program requiring an extra year of full- time study (or 18 months part-time study) on top of your undergraduate degree. What is Honours? The Bachelor of Science Honours program (SZ8) is an additional fourth year of Undergraduate studies, completed over 9 months full-time (FT), or 18 months part-time (PT). The main objective of the program is to train students as professional research scientists. Honours students engage in an individual research project under the close supervision of an academic staff member with relevant expertise in their chosen field. Students also complete theoretical coursework designed to complement their research and develop key skills in communication, critical analysis and project management, equipping them for independent research roles in the workplace or for entry into postgraduate research programs. For more program information, see Honours course outline and Honours courses and assessment. Why complete an Honours year? For some students completing honours is the first step towards building an academic research career and pursuing post graduate study. However, completing an Honours year also offers many benefits to those looking to boost their marketability in an increasingly competitive job market.

  • Microseris Walteri Murnong Friends Friends
    Plant in Focus, September 2017 Microseris walteri Murnong Friends 1. Introduction Murnong Microseris walteri was an important plant in the life of Aboriginal people in Western of Victoria and other parts of south eastern Australia. Its tubers provided a consistent supply GeelongBotanic Gardens of energy-rich food for more than half the year. It was widespread, prolific and easy to harvest because the tubers grow close to the soil surface. The Murnong is a yellow-flowered daisy in the milky sap tribe (Cichorieae, also called Lactuceae), of the daisy family Asteraceae. Like many daisies its small seed sit below a parachute of bristles. This ensures the wind catches the seed, separating it from the plant and carrying it some distance. The rich volcanic soil of Western Victoria provided an ideal growing medium for these 1. Murnong Microseris lanceolata flower head, NSW plants, and for grazing sheep. (Image captions show the species name recorded with The Murnong tubers allow the plant to survive the specimen. See discussion on naming.) the hot dry summer conditions in the relative cool below the surface. New shoots appear with the rain in late autumn or early winter. This growth depletes the tuber. A new tuber begins to form once the plant’s leaf growth is well established. The shrivelling old tubers and tiny new ones are not very nutritious, so there are a few months when they cannot be eaten. 2. Aboriginal food use In 1803, when Collins tried to establish a settlement on the eastern side of Port Philip Bay, a convict, William Buckley, escaped and lived with aborigines for 32 years.

  • Powerful Pollinators Encouraging Insect Pollinators in Urban Environments & Gardens
    Metropolitan & Greater Melbourne: Western Powerful pollinators Encouraging insect pollinators in urban environments & gardens Pollinators are an essential component of our cities and suburbs. Enhancing pollinator resources to support a diverse range of beneficial insects is important for flourishing gardens, sustainable backyards, healthy green spaces, and thriving ecosystems. The Powerful Pollinators Guide provides an introduction to encouraging insect pollinators in the western suburbs and surrounds of urban Melbourne. The power of pollinators Pollinators – mostly insects, but also birds and mammals – assist the formation of seeds and fruit in many plant species by visiting flowers in search of food (nectar and/or pollen). Whilst foraging they transfer pollen from one flower to another, facilitating fertilization, which results in fruits and seeds.
