Members of GFLG are regularly control and remove weeds in the Goodmans Ford area and along the Wombeyan Caves road .
Some of the weeds targeted are :
- aquatic Water Primrose in Wollondilly River
- Pioneer plants of Fireweed along the W. C. road
- Negoora Burr in the Council Reserve at Goodmans Ford
- St. John's Wart in the Reserve and other weeds .

Most of this is done by HAND PULLING the savest method of weed removal . It is important to attack investations early , bevore the weeds spread too far and cannot be controlled by hand pulling any longer .

A trial where horses are used to graze Serrated Tussock is also started , works well , but it is important to provide sufficient good hay for the horse , too . As there is no feeding value in Tussock . We found , that in places where Tussock can be mowed / slashed or grazed regular it will disappear and other , more desirable plants will take over . This prooved to be the case for several broud leaf weed species wher we mowed the river banks down to the water edge . The resulting good grass cover improved the stability during floods dramatically .

The most important thing with weeds is and always will be :

Good knowledge to identify dangerous weeds , constant surveillance and early action when new investations occur .
