Stop the Wildflower – Waratah Theft

Waratahs (Telopea speciossisma) are in full flower at the moment and some of the best wildflower displays you can see are within Brisbane Water National Park around the Warrah Trig area on the NSW Central Coast, just north of Sydney.

Unfortunately, Waratah blooms are being poached from the bush and Cathy Offord from the Royal Botanic gardens, Mt Annan and I  conducted a study on efforts to reduce Waratah poaching by painting some of the flowers with blue paint. The study revealed that although the painting did reduce the rate of theft a little, there was not a real difference between the rate of theft between painted and unpainted flowers.

Full details of the study is now published in Cunninghamia the ecological journal of the Royal Botanic Gardens, Sydney, and Tim Entwisle has also an online article.

The flowering of these trees also marks the end of year exam time for schools and technical colleges and I remember when I was studying Horticulture in Sydney, I used to have lunch at the top of a hill overlooking Sydney and I remember vividly Read more

Somersby Mintbush recovers from fire by producing seedlings.

I was involved with the burning of a patch of bush at Somersby on the Central Coast of New South Wales which contains some of the Endangered plant Somersby Mintbush (Prostanthera junonis).

The plant grows near the town of St Albans on the MacDonald River in New South Wales and is regarded as endangered. Read more

When working in the area around Tamworth area in northern NSW Australia, while conducting a vegetation survey of the riparian zone, I was fortunate enough to be able to visit the Dungowan Dam catchment area and it was here that I made an interesting discovery.
