Blackberries are classified as a noxious weed and it is this time of year that is ideal for treating the plant with poison.
Please be aware that, as part of the annual maintenance program, blackberry spraying has started. This means we cannot eat the fruit.
The blackberry plant can be quite attractive and the fruit quite tasty; however, the plant is not so good, environmentally speaking.
Impact on ecosystems and waterways
The blackberry is considered a serious environmental threat and is highly invasive. It can provide harbour and a food source for pest species, as well as serve to outcompete and eliminate other vegetation by excluding light from the soil surface.
In its early stages of infestation, blackberry will grow over, or occupy, gaps in native vegetation and, in later stages, can severely restrict regeneration in native forests (Department of Primary Industries, 2012.)
