The "Great" Cumberland Forest

"Some good farming might be made. Some places were rather stoney but in general I  have not seen so good forest land in the country"
1805 - George Caley - Self taught botanist under Joseph Banks

European timber getters were the first to settle the North Shore in the early 1800's. By the 1830's a saw mill was established (near Cowan Road in 1831). Bluegum, blackbutt, stringybark, turpentine and ironbark were felled from the great forest to build Sydney. The cleared lands were converted to farms and orchards. Later these became the suburbs.

The Bradley Method


Joan and Eileen Bradley developed a series of weed control techniques in the 1960's through a process of trial and error.The Bradley method is a simple approach in that it encourages native vegetation to regenerate rather than seed or direct planting. They demonstrated and proved their method by successfully clearing weeds from a 16 hectare woodland reserve near Ashton Park in Mosman, Sydney. Noteworthy is their technique requires little maintenance, as little as once or twice a year, mainly in vulnerable areas such as creek banks, verges, and clearings.

The hallmark Bradley method principles,
1. Secure the best areas first
2. minimise disturbance to the natural conditions (e.g. soil and surrounds).
3. Don't overclear, let the regenerative ability of the bush set the pace of clearance

(after Bradley 1988).
