Invasive Species

If you have invasive plants on land that you own or occupy, you must comply with specific legal responsibilities, including:

  • spraying invasive plants with herbicide
  • cutting and burning invasive plants
  • burying invasive plant material on site
  • disposing of invasive plants and contaminated soil off site


Wildscapes has experience in removing and disposing of many invasive species, such as japanese knotweed, ragwort, giant hogweed, Crassula and himalayan balsam. All our operatives are fully trained in herbicide application including application to water (PA1 & PA6AW qualified).

 

CASE STUDIES

Client: Sheffield City Council

Sites: Bannerdale Centre and Denmark Street

2014: Wildscapes were contracted by Sheffield City Council to manage japanese knotweed through stem injection at it's Bannerdale Centre and Denmark Street sites. Stem injection involves injecting herbicide directly into the stems of the plants. The traditional spraying method would have had a great effect on the dense vegetation in the surrounding area; stem injection can be used where spraying isn't suitable.


Client: Sheffield City Council

Site: Parkwood Springs

2013: Wildscapes were contracted to cut back vegetation, and conduct spraying works in rock fall traps on an area of scrub land between Parkwood Springs and the Oakham Drive industrial estate. The contract involved cutting back light vegetation to ground level using hand tools.

The area was then sprayed with Glyphosate at the manufacturers recommended dilution rate to kill off all vegetation. This area is classified as a SSSI due to its geological interest and is situated on a steep sided slope that contains two bunds to capture rockfall. This meant that access to the site was difficult and the work area itself was hazardous. These issues were addressed in both our method statement and risk assessment and steps were taken to reduce any impact on the site when delivering the work.

 

Client: Wakefield Council

Sites: Upton Ponds & multiple sites across Wakefield

2012-present: Wildscapes has been contracted by Wakefield Council to manage japanese knotweed (Fallopia japonica) at 7 sites across Wakefield. Japanese knotweed is a highly invasive species requiring specialist treatment over many years; this is our second year of treating these sites.

We have also been taking part in the control of Crassula helmsii (New Zealand Pygmyweed) at the Upton Ponds site. Treatment for this will be spraying with glyphosate, then spraying again 3-4 weeks later, once the plant has weakened slightly.
