Summer colours

With the arrival of summer most of the colours that enchanted us during spring have faded, and left us with subtle gold and green. However, a few brave flowers continue, especially the intense mauve of the fringe lilies (Thysanotus sparteus) and the pale Prince of Wales Feathers (Ptilotus polystachyus) and gold of the local grasses (Stipa compressa (or variant)).

City of Nedlands - summary of weed control

Vicki has sent me summary information of weed control activities the City of Nedlands has engaged in during 2009.






This map shows a miscellany of weeds noted - fountain grass, flinders ranges wattle (to remove), lachenalia, and vetch.

There is quite a bit of African Love Grass (Eragrostis curvula) in the Health Department land. This was sprayed this year to stop it spreading into the bushland.

This is the lachenalia sprayed by City of Nedlands contractors this year.
Black flag is a major concern for us - not least because there does not appear to be any herbicide to control it.
Vicki had it sprayed with Dalapon this year

This shows areas of black flag identified.

Searching for those elusive watsonias

It is one of those facts of life all bush regenerators face - the more successful we are in reducing the population of a particular weed, the more difficult it becomes to find those last few plants that we really need to find in order to eradicate an infestation.
Fortunately,Watsonia plants are pretty easy to spot from a distance, especially when they are big enough to flower. We found a few plants on sunday, and in between searching for Watsonia we removed any perennial veldgrass we came across.
