Invasive weed management

Invasive weeds can cause problems with planning applications and construction sites by undermining structures and eroding foundations. Some can be dangerous to touch and poisonous to livestock. ATV creates professional plans and delivers tailor-made services to clients across the country requiring weed management. Book a survey with us today and we can make your environment a better place.

We offer advice and solutions to manage invasive species by

  • identifying and mapping all infested areas on site
  • cordoning off areas to avoid contamination and further pollination or spread
  • creating a bespoke treatment plan, for example, spraying programme, stem injection or disposal to quarantine
  • providing and monitoring of treatment plans, for example, trial hole digs for Japanese knotweed rhizome
  • delivering a weed-free outcome.

ATV Japanese knotweed

Japanese Knotweed

Japanese knotweed (JKW) is a very distinctive invasive plant with bright green leaves and stems resembling bamboo. In late summer, it has small white flowers that attract wide-ranging native insects, including butterflies and bees. JKW can reach upwards of 4 metres and grow 10 cm daily. It spreads through rhizomes underground, and its root system can grow two metres and spread even further. If JKW is untreated, it may be a problem and cause damage to paving and buildings by growing through cracks and forming large crowns. Smaller stands can be treated using a herbicide (glyphosate), but larger stands may need excavating.

ATV Ragwort

Ragwort (stinking willie)

Ragwort contains many different types of alkaloids, making it poisonous to certain animals, primarily horses and cattle. Ragwort is found almost everywhere in the UK. Its distinctive yellow flower is similar to a daisy, but it can grow 90 cm in height. It is a good nectar source for native pollinators and is eaten by caterpillars, which also absorb the alkaloid, thus making them poisonous to predators. Hand-pulling ragwort is possible once seeds are not present; however, spraying with a herbicide is more effective.

ATV Giant hogweed

Giant Hogweed

Giant hogweed is a photo-toxic invasive plant. Chemicals in the sap can cause photodermatitis or photosensitivity, whereby the skin becomes very sensitive to sunlight. It can blister human skin, leaving pigmentation and scars. It is a noxious weed in many jurisdictions and can grow upwards of 3.5 metres; its flowers can reach a diameter of up to 60 cm. It looks similar to cow parsley, a common and harmless native weed, but it grows on a much larger scale. Spraying it with herbicide is an effective treatment; however, because of its toxicity, great care should be taken when treating it, primarily covering the skin to avoid direct contact with the plant.

ATV Himalayan balsam

Himalayan Balsam

The Himalayan balsam is a relation of the busy lizzie, but it can grow up to 1.8 metres in height. It is a ground-covering plant, spreading through its exploding seed pods. These pods are activated by the slightest touch and each plant can spread up to 750 seeds. It is very attractive to native pollinators, causing the plant to spread when the pollinator lands on the flower. Himalayan balsam promotes riverbank erosion owing to its death over winter, leaving riverbanks unprotected from rising water. The Himalayan balsam can be pulled by hand before the flowering season. Alternatively, one can treat it with a herbicide, such as glyphosate, but this treatment needs to be done before the plant flowers.
