Council urging continued adherence to Fireweed control measures
November 21, 2011
Shoalhaven City Council is encouraging rural landowners to continue Fireweed control measures throughout the area following an increase in local weed numbers.
Fireweed is a highly invasive and opportunistic weed which can quickly colonise overgrazed areas and disturbed pastures.
Native to east Africa, the weed can reduce the grazing capacity of a property, decrease pasture potential, reduce livestock growth rates and incur high control costs.
With the Shoalhaven having experienced large temperature swings throughout spring following a cool wet winter the area has become inundated with fireweed following multiple germinations in parts of the City.
Council Noxious Weed Manager, Ian Borrowdale said while Fireweed infestations were currently coming to the end of the growing season it was important all landowners continued control measures given the exceptional growing season.
“While Fireweed generally grows between March and late October the recent growing conditions have resulted in a large increase in the weed locally,” said Mr Borrowdale.
“Fireweed usually adopts an annual growth habit which means the plant will germinate, grow, set seed and die as summer approaches.
“However, this weed is so adaptable that it can have multiple germinations throughout the one growing season while adopting a perennial growth habit extending through summer if presented with suitable conditions.”
“It is vital that all landowners continue control measures, particularly in cases where the new plants have germinated or before the older plants can set seed.”
Mr Borrowdale said to correctly control Firweed infestations, the landowner must break the seeding cycle and prevent plants from setting future seed.
Management options will differ depending on the property and size of the outbreak.
