Environmental weeds

20 years ago

Here are a few photos of common garden plants that are also tantamount to ENVIRONMENTAL CANCER. I am gradually collecting a file of such photos for use in public education and thought I would share them in this forum.

The photo is an example of a Gazania daisy infestation, in Goonawarra Golf Course in Sunbury. This was planted in the car park garden beds and has spread across and down the road sides, with plants up to a kilometre away from the golf course.

You will note the almost complete lack of biodiversity within the infestation. Now a good patch of the indigenous plant Dianella revoluta normally excludes other indigenous plants for perhaps 2-3 square metres. However environmental weeds can exclusively occupy hundreds or thousands of square metres, to the exclusion of even other environmental weeds!
