Expert Witness
Authoritative expert testimony and litigation support for encroachment, property value, and professional negligence disputes.
The Standard in Evidence-Led Invasive Plant Management
Founded in 2016 as a spin-out from Swansea University’s Department of Biosciences, Advanced Invasives bridges the gap between academic rigour and real-world application.
Led by Dr Daniel Jones, we provide the technical, legal, and strategic insight required to solve the most complex challenges posed by invasive plants, with a specialist focus on Japanese Knotweed.

We mitigate risk, protect assets, and provide the scientific certainty necessary for global leaders, large landowners, and government bodies to act with confidence.
Advisory & Integrated Project Services
Even the best-managed organisations need specialist advice to mitigate risks during critical stages of an asset’s development or investment lifecycle.
Our Six Core Pillars of Excellence
We operate at the intersection of science and strategy, applying evidence-led thinking across legal, commercial, environmental, and operational contexts.
01
Authoritative expert testimony and litigation support for encroachment, property value, and professional negligence disputes.
02
ai:LAB tests, refines, and validates new methods so clients use solutions backed by data rather than anecdote.
03
Data-led Integrated Pest Management for clients managing invasive species as a long-term asset risk.
04
Forensic site detail and landscape-scale geographic analysis that uncover what standard surveys overlook.
05
Technical and logistical certainty for ecologically sensitive sites, infrastructure, and high-value developments.
06
Professional development and accredited training that translate research into commercial practice.
Strategic Impact and Outcomes

“My goal was never just to kill weeds. It was to build a framework where land management decisions are based on data, not anecdotes.”
Meet the Founder
Dr Jones is a leading authority on the ecology and management of invasive plant species. His doctoral research at Swansea University into the long-term management of Japanese Knotweed is among the most extensively cited work in the field.
As a Full Member of The Academy and a Certified Expert Witness, Dr Jones translates complex biological data into clear, actionable insights for legal teams, global corporations, and government bodies.
