Regeneration techniques

Bushcare volunteers receive introductory and ongoing training in bushcare techniques from qualified and experienced BMCC bushcare officers. Volunteers may opt to not use herbicide at South Lawson Park bushcare sessions. All tools, gloves and kneeling pads are supplied by the bushcare officer.

We engage in a wide range of activities, as illustrated below, and bushcare is not just about weeding!

Some prominent pioneers of bush regeneration in Australia were Ambrose Crawford in 1935 and onwards on the NSW north coast, Albert and Margaret Morris in Broken Hill in the 1930s and 1940s and Joan and Eileen Bradley in Sydney in the 1960s and 1970s.

The Bradley Method was developed by the Bradley sisters and subsequently refined by other bush regeneration practitioners. It provides the basis for BMCC bushcare practice in the Blue Mountains. The core principles of the Bradley Method are:

  1. Work from the good bush towards the weeds.
  2. Try to minimise disturbance of the soil and native plants and seedlings on the site, as weeds thrive in disturbed areas.
  3. The rate of weed clearance is determined by the rate of native plant regeneration.

The Australian Association of Bush Regenerators is the recognised industry body. Go to http://aabr.org.au for some interesting reading and information.
