WEED: Lachenalia alioides (soldiers)

Ashleigh Coombs - Thursday, August 24, 2017

Hi NRM community 

Thank you for the email. This looks like the introduced plant Lachenalia aloides, commonly called soldiers.

This is a plant species with few collections (only 11) from South Australia, most from ALMR, one from KI, and one near Mount Gambier see:

http://flora.deh.sa.gov.au/google_maps_data.html?census=1&name=Lachenalia_aloides&name=Lachenalia_tricolor&name=Phormium_aloides#topmap

Check out this website as it has some good images of the plant, and is a great web site for bulbs in general, worth ‘adding to favourites’.

It does look like it could be a problem (that’s my feeling), and is regarded by some as a sleeper weed. For further information on this as an ‘Alert weed’ and this includes limited control methods, etc. See: https://www.environment.gov.au/biodiversity/invasive/weeds/publications/guidelines/alert/pubs/l-reflexa.pdf

& for chemical control, see: https://florabase.dpaw.wa.gov.au/browse/profile/13562

& general basic info (no control info): https://www.agric.wa.gov.au/weeds/bulbs-become-bushland-weeds?page=0%2C2

I would dearly love a collection, from all locations / populations you find. If anyone else finds this, a collection would be great! Please find the attached collection sheet to include with your collection. Please dig up the bulb and you can cut this open to help with drying. Please include all the leaves and flower if you can. I’ll need a specimen to add the records to the dataset, an email and photos don’t make it on, so sorry.

I’ll try and spread the word about this. Perhaps you could spread the word in the wider NRM / bush care community? It’s you guys out and about, killing nasties that can jump on it and stop this potential new weed from spreading.

And NO you are not a pain, I really appreciate your email and I’m always here to help with the identification of weeds.

Please contact me any time! However, I will be away on annual leave for most of September and early Oct, so you may not hear from me during that period.

However, Chelsea (CC ed in here) will be available to answer questions or push emails through to others that can help when she is about, ( I hope, Thanks in advance Chelsea).

Kind regards

WEED: Buffel Grass - Cenchrus Ciliaris

Ashleigh Coombs - Friday, September 02, 2016

Please find the attached flyer and registration form for the upcoming buffel grass project forum to be held on the 25th and 26th of October 2016 in Adelaide. If you could please post this on your friends of parks website with the other buffel grass content that would be greatly appreciated. Please also feel free to distribute to any other networks that may be interested in attending.

The target audience for the forum is local councils, regional NRM authorities, conservation/volunteer organisations, pastoralists and indigenous ranger groups as well as the mining/transportation industries. I’m planning to have a variety of speakers primarily from SA although also have representatives from WA, NT, Vic and QLD. Topics will include a detailed summary of my project (i.e. Herbicide trials, roadside surveys, criteria based prioritisation tool, strategic response activities etc.) in addition to a number of control case studies and speakers on the impacts on ecology, fire regimes and the use of various herbicides for the control of buffel grass.

The forum is free of charge and will be held at the Plant Research Centre, University of Adelaide Campus , Hartley Grove, Urrbrae South Australia. Refreshments will be provided on the day and there will be a dinner on the first night to provide an opportunity for further networking (at the expense of attendees).

Kind Regards - Troy Bowman

I am writing to provide some information regarding a weed of concern that has the potential to devastate the biodiversity of South Australia.

Buffel Grass (Cenchrus Ciliaris) has been widely recognised as one of the greatest pest threats to South Australia. It is often referred to as a transformer species meaning it has the ability to alter entire ecosystems through the alteration of fire regimes and through competition with native flora and fauna.

In recognition of its social and environmental impacts, buffel grass has been declared as a weed under the Natural Resources Management Act 2004. The act restricts the sale and movement of buffel grass or contaminated material as well as outlining responsibilities of landholders and members of the public.

Please find the attached Federal Government Threat Abatement Advice and fact sheets on the identification, control and vehicle hygiene associated with buffel grass FYI.

Please also find the link below to our buffel grass webpage which contains further information about the distribution of buffel grass in SA, our strategic plan and actions that have been taken to manage this weed throughout South Australia.


I would appreciate if you could forward this information through you networks and encourage the reporting (to your local Natural Resources Region) and control (through volunteer activities) of buffel grass infestations to prevent the devastation of our parks and the biodiversity of SA.

Please feel free to contact me if you require any further information.

Kind Regards
