I took the first and second photograph of a large Cootamundra Wattle that I frilled 11 years ago - the axe marks are still visible in the first photo. there were several small CWs growing in the debris of the frilled wattle presumably from its seeds stored in the soil - you must have a long breath to control Cootamundras .... This shows how crucially important follow-up and monitoring of sites is that have been previously tackled.
