'Invasive' Himalayan balsam spreading in Haverfordwest
Himalayan balsam, known for its explosive seed capsules, has been seen spreading along the riverbanks in the town centre, between the John Phillipp Bridge and the area near the Bristol Trader pub.
John Roberts, a former parks trainee who was taught about the dangers of such plants in the 1950s, has warned the town could be in for 'seven years of weeding' due to the plant's rapid proliferation.
Despite its attractive appearance, the Himalayan balsam is legally recognised as an invasive plant due to its rapid spreading nature.
Mr Roberts said some attempts have been made to control the plant, possibly by volunteers, but said the plant is proving challenging due to difficult access.
He called for professional intervention to prevent the plant from spreading further downstream.
In an open letter, Mr Roberts said: "Himalayan balsam, Impatiens glandulifera, is an invasive watercourse weed.
"In the town centre, it is being allowed to proliferate along the river, between the two bridges.
"This is despite the fact that the Pembrokeshire County Council (PCC) 'Short River Walk' website states that, 'The project includes management of the invasive Himalayan balsam.'
"Some attempt has been made to control the weed by bashing.
"Possibly by volunteers?
"However, access is difficult and control of this weed needs professional attention before the weed spreads down river to the open area opposite the Bristol Trader.
"I would remind PCC of their stated intentions regarding invasive weeds, such as Himalayan balsam."
The Royal Horticultural Society (RHS) website provides guidance on how to manage Himalayan balsam, stating it is important to preserve and promote indigenous flora and fauna.
Mr Roberts acknowledged the current efforts by the Pembrokeshire County Council in wilding, but urged for a balance to ensure that wilding does not become neglecting.
