Knotweed Report & Mapping
Knotweedcontrol.ie has launched a unique, groundbreaking Japanese Knotweed identification report for local Authorities, Ecologists and NGOs.
Japanese Knotweed is a highly invasive, destructive plant species that may in the futher dramatically impact on property asset values and suitability as lending security. (Depending on Irish banks following UK guidelines)
Knotweedcontrol.ie will carry out field-work to record and identify Japanese Knotweed on and adjacent to commercial property sites.
The report will allow surveyors, developers and commercial conveyancers to highlight lending risks to clients and potential management costs ahead of purchase decisions.
Our Japanese Knotweed report is the only cost-effective way to understand the risks of Knotweed ahead of valuation.
Key features of the Japanese Knotweed report:
Ordnance survey Streetview location map
Site boundary polygon with 250m radius buffer
Polygon areas for Knotweed stands greater than 5m2
Indicative buffers showing potential coverage of root system
Provision of Japanese Knotweed treatment options, tailored to available time scales and budgets
Free follow up plant verification service

Clerk of Works (watching brief)
We offer a Knotweed Clerk of Works service. The Environment Agency Knotweed Code of Practice 2013 highly recommends that developers have a Clerk of Works responsible for the management of Japanese Knotweed.
In addition we also carry out Invasive Species Surveys & Reports. These surveys can account for Japanese knotweed, and other common invasive plants such as: Bohemian/Hybrid knotweed, Giant knotweed, Giant hogweed, Giant rhubarb (two species), Himalayan knotweed, Himalayan Balsam, Hottentot Fig and Rhododendron.
Knotweedcontrol.ie can also provide GIS and Google maps of rivers, woodlands and forests to show the presence and density of Japanese Knotweed and other Invasive species.
