10 Nov 2017 – The Americans are Coming!

Ian Higgins is the guest speaker for the November CFNC meeting.  Ian is a renowned local botanist, and was recently recognised as the 2017 Victorian Landcarer of the Year for his work with the Friends of Campbells Creek Landcare group.

Ian’s talk, ‘The Americans are coming’, is to be about the invasive stipoid needle grasses that are spreading across many parts of Australia, including the local area.   His talk will cover:

Chilean Needle-grass (photo from the NSW DPI website).

What are they?—the seven species currently known (or prohibited in the case of Mexican Feather-grass) from Victoria
Where are they? i.e., where known to exist in Victoria and in our district.
Why are they a problem? Their behaviour and the threat posed to natural values
How can I identify them? Identification characteristics, especially how to distinguish them from native grasses
How are they spreading?  Dispersion strategies and human involvement.
How to manage them?  Duration of seed viability in soil, herbicides, etc.

Ian has also offered to help members and visitors to identify different grass species on the night.  If you have a specimen that you suspect is a weed, bring it along (preferably in a sealed plastic bag to prevent the spread of seeds).

The meeting is to be held from 7.30pm on the second Friday in November (10th Nov). Members and visitors all welcome.  It will be at the Uniting Church on Lyttleton St, Castlemaine – next door to the Art Gallery.  Due to exams being held in hall, this talk will be held in the chapel at the rear of the main church building.

There is to be an excursion on the following day (Sat 11th Nov) to view some stipoid grasses in the field with a specialist.  More details to follow soon.
