The ACT situation
The ACT Agriculture Bulletin in 1950 described the distribution of St. John's wort in the Australian Capital Territory (ACT) as found in only scattered patches. This Bulletin went on to comment that St. John's wort is potentially one of our worst weeds. Today, St. John's wort is widespread throughout the ACT, particularly in forest plantations, nature reserves, roadsides, rural lands, and Canberra's urban landscape. The rate of increase has been considerable over the last five years.
