Helping to tackle Serrated Tussock

/in , , , , /by

As part of the Nasty Nassella Serrated Tussock project, which is working on a new approach to serrated tussock, Watershed Landcare is inviting local landholders to a workshop to help them get the upper hand on this weed of national significance.

Serrated tussock

Watershed Landcare has partnered with Central Tablelands Local Land Services (CT LLS) and Mid-Western Regional Council (MWRC) to deliver the Nasty Nasella Workshop on Monday, 5 March.

The workshop will feature presentations from Clare Edwards, CTLLS Senior Land Services Officer (Pastures), who will discuss proactive whole-farm strategies to manage serrated tussock; Aaron Simmons, NSW Department of Primary Industries, will speak about the practicalities of serrated tussock management strategies from his perspective as a landholder and researcher; Matt Anderton, MWRC, will discuss landholder responsibilities and the new biosecurity legislation.

The Nasty Nasella workshop will be held from 9am-12:30pm, 5 March at The Stables, Market Street, Mudgee. This event is free to attend with lunch provided, but please RSVP to assist with catering by Friday, 2 March.

The Nasty Nassella Serrated Tussock project is also looking for farmers interested in developing a serrated tussock management plan for their farm.

“The project is capturing and building on the knowledge of experienced landholders as well as supporting those who have had limited experience with serrated tussock,” said Watershed Landcare Coordinator, Claudia Wythes.

“Rather than focusing only on chemical control, this project will deliver a broad range of practical management options that cater to landholders with different experience levels in dealing with the problem.”

“Pasture species, alternative control strategies and the scale of the problem all need to be considered,” she continued.

“Whether you are actively managing serrated tussock on your property, you have just spotted a few isolated plants, or you would like some help with identification, we want to hear from you,” said Ms Wythes.

To RSVP to the workshop or for more information about the Nasty Nassella project, contact Watershed Landcare Coordinator Claudia Wythes on 0412 011 064 or email: claudia.wythes@watershedlandcare.com.au.

This project is supported by Watershed Landcare through funding from the Central Tablelands LLS from NSW Catchment Action and the Australian Government’s National Landcare Programme and is a part of the NSW Government’s Local Landcare Coordinators Initiative, supported through the partnership of Local Land Services and Landcare NSW.

Need help managing serrated tussock?

Watershed Landcare are launching a new project to help landholders manage serrated tussock on their properties.

The project, funded by the Central Tablelands LLS through funding from NSW Catchment Action and the Australian Government’s National Landcare Programme, will deliver a broad range of activities catering to landholders with different experience levels in dealing with serrated tussock.

Serrated tussock

“Building on interest in serrated tussock management in recent months, we have received funds from Central Tablelands LLS to help landholders develop management plans that take in a range of factors that are critical to managing serrated tussock.” said Claudia Wythes, Watershed Landcare Co-ordinator.

“Things like grazing management, pasture species, control options and the scale of the problem all need to be considered.” she continued.

The project will utilise mentoring and support to develop a whole of farm approach to serrated tussock management, rather than focussing on individual control methods or strategies.

Participating landholders will have the opportunity to develop a serrated tussock management plan, tailored to their property, as well as some funding to assist in implementing some of the identified actions.

“A number of workshops will be held over the coming months including identification and grazing management. For those landholders who have been managing serrated tussock for some time, we are keen to trial alternative ideas you may have as well as give you support as it can be a tough battle to fight on your own.” said Ms Wythes.

Want to get involved? Whether you are actively managing serrated tussock on your property, just spotted a few isolated plants or would like some help with identification, we want to hear from you.

For further information or to register your interest contact Claudia Wythes, Watershed Landcare Coordinator, on 0412 011 064 or claudiawythes@watershedlandcare.com.au.

Weed control during winter

/in , /by

The ideal time to control most weeds is when they are actively growing. This is usually in the warmer months. There are a few that can be controlled at any time of the year.

Two of those significant to this area are Serrated Tussock (Nassella trichotoma) and Cineraria (Cineraria lyratiformis). Both species are, unfortunately, common, and have adaptations for wind dispersal, but can also be spread by water, contaminated fodder, animals and vehicles.

Cineraria

Cinneraria has bright yellow flowers with eight petals which are borne in flat topped clusters at the ends of the branches. Mature leaves are oblong in shape and deeply divided. Juvenile leaves are small and rounded with soft serrations, somewhat similar to geraniums.

Cineraria is an annual plant that can grow and flower through winter. Being an annual, the root system is not very extensive and most plants can be pulled out.

This plant has the ability to produce seeds even if it is pulled out with young buds present. Therefore plants with any sign of a flower or bud must be bagged and later destroyed. At present there are no chemicals registered for Cineraria lyratiformis.

Cineraria is palatable to sheep and can be effectively controlled by confining a number of animals over an infestation. This plant is highly invasive and a dense perennial pasture is the best way of preventing seedling survival.

 

Serrated tussock

Serrated Tussock is a highly invasive perennial grass, which, if left untreated, can take only seven years to dominate a pasture or native grassland. It has virtually no grazing value due to a high fibre and low protein content.

The leaves of Serrated Tussock are very fin

e and when rolled between the index finger and thumb, roll smoothly – like a needle. In Autumn and Winter the leaves are a yellow-green, the tips of older leaves are often bleached by frost.

Isolated Serrated tussock plants can be dug up before flowering and turned upside down so no roots make contact with the soil. Fluproponate is the main chemical used in the control of Serrated Tussock. It is a residual chemical that will stop seedlings emerging for a period of about 2 years. Fluproponate is somewhat selective in that it will only kill certain types of grass. However, many of the grasses susceptible to Fluproponate are highly beneficial.

As with Cineraria a dense perennial pasture is the best way of preventing seedling survival.

Further information for identification of Cineraria can be found on the web, for example http://www.dpi.nsw.gov.au/biosecurity/weeds or http://plantnet.rbgsyd.nsw.gov.au.

There are also many good resources for Serrated Tussock on the web. However, Serrated Tussock as a grass is a lot more difficult to identify, and more importantly, to distinguish it from other similar species. A hands on approach is recommended. Watershed Landcare will be offering a short session to help landholders identify Serrated Tussock and other similar grasses at the Mudgee Small Farms Field Days in July.
