Weeds

This page lists the more common and conspicuous weeds found in coastal dunes, 16 of which are as described and illustrated in Professor Kingsley Dixon’s book ‘Coastal Plants – A guide to the identification and restoration of plants of the Perth region’, published by CSIRO Publishing and copyright to Cambridge Coastcare Inc in 2010.  Clicking on a common name will open a copy of the relevant section in the book, complete with plant photographs.  We have added a DPIPWE publication on Sea Splurge, and two papers on pigface hydrids, both of which have emerged as problem weeds in recent times.

Photos and descriptions of 39 weed species can be found on Cottesloe Coastcare Association’s website – http://cottesloecoastcare.org/dir/weeds
