'Poisonous plant' fears at popular Yorkshire dog walking spot

Kirklees Council have assured that an “invasive” plant is not poisonous to horses after it was spotted near a Huddersfield bridleway.

Posted to public group Friends of Grimescar, residents were “sad to see” that Japanese Knotweed was growing along a bridle path through Reap Hirst Road.

The plant is among the most aggressive, destructive, and legally regulated invasive species in the world, and is known to cause mile discomfort in horses if consumed in large quantities.

More worryingly, the plants are often treated with strong herbicides, which can be toxic to wildlife and livestock if consumed. Yet, Kirklees Council have urged that they “remain committed to controlling identified outbreaks of this species” with an “industry-approved” herbicide.

David Shepherd, Executive Director for Place said: “We understand concerns raised about the presence of Japanese knotweed, particularly regarding safety for horses and the surrounding environment.

“The council remains committed to controlling identified outbreaks of this species that is now commonly found across the country. Since we received reports of Japanese knotweed growing on Reap Hirst Road in 2023 it has been professionally treated twice a year with industry approved herbicide.

"This is a recommended action for treating this invasive species. Our specialist teams are currently doing weed spraying across the district and this area will be receiving another dose shortly.

“The treatment has successfully controlled the spread of the weed which can now only be found in two small patches on the bridleway. We will continue with this course of treatment and monitoring until it is no longer present.

“The plant is not poisonous to humans or horses and would only cause discomfort if consumed in large quantities, which is highly unlikely in this setting where horses are supervised.

Kirklees Council further assured that the plant is not poisonous to humans or horses and would only cause discomfort if consumed in large quantities, which is highly unlikely in this setting, where horses are supervised on the bridle path.
