Great Britain has almost as many as 200 types of invasive non-native species. More than 3,000 are currently residing across urban and rural areas. For developers, it can be a real problem because certain categories of invasive species are capable of damaging infrastructure, overpowering non-invasive native species, and even negatively impacting human and animal health.
Non-native invasive species can appear on development sites, and when they do, the local planning authorities will need assurances that they’ve been dealt with properly or will refuse planning permission. Advanced biosecurity planning and expert witness services can help at different stages in the planning process when it comes to the legal compliance of invasive species management.
Both services work together in planning projects, but each focuses on distinct areas:
Various legal implications are involved with biosecurity planning and expert witness services.
In terms of biosecurity planning services, compliance with relevant UK laws is an important aspect affected by the Environment Act 2021, the Invasive Alien Species (Enforcement and Permitting) Order 2019 and the Wildlife and Countryside Act 1981. It is also restricted by planning conditions and the potential for the legal consequences of biosecurity failures, such as enforcement notices, fines, prosecution, and civil liability and compensation claims.
As for expert witness services, there could be overlap with planning appeals and public inquiries, as well as a need in disputes over the compliance of biosecurity, such as in compensation cases, judicial reviews and negligence claims. Although less common, a criminal prosecution could call for the input of an expert witness if a developer illegally removed or disposed of contaminated soil containing an invasive species, for example, violating waste disposal laws and contributing to an unwanted spread.
A biosecurity plan is a structured document that explains how best to prevent, control and mitigate the introduction and spread of invasive species, pests and diseases in a given location. Once invasive plant species such as injurious weeds, Japanese knotweed, Himalayan balsam or giant hogweed have been found on a development site, biosecurity measures will be made to address them on a long-term basis.
Due to the effect of invasive species, biosecurity plans can help with building or land development projects, but also such things as agriculture, aquaculture and environmental conservation. For example, an on-site farm biosecurity plan for a dairy farm, poultry farm or horse farm would reduce the risk of introducing disease to the area or causing a disease outbreak to the present cows, chickens and horses.
Included within a biosecurity plan are:
An expert witness service allows developers to get specialist further information, guidance and insight on issues relating to or caused by invasive species from advanced ecological consultants. It shares similarities with ecological clerk of works (ECoW) services, but while ECoW is a proactive on-site role, expert witness is an off-site reactive role.
Input from an expert witness would often be needed in extremely difficult situations involving biosecurity risks, invasive species and environmental compliance, such as compensation claims, legal disputes, planning appeals and regulatory cases. If a developer was accused of spreading an invasive species, for instance, the expert witness would visit the site, create a report, and testify in court.
At any point that an ecological consultant is instructed to work with a developer to provide biosecurity planning and expert witness services, a specific process will be followed. It contains a mix of mandatory and optional stages, all undertaken within legal, regulatory and good practice guidelines.
*Optional if:
– A local planning authority rejects a biosecurity plan and the consultant needs to provide evidence in the appeal
– The developer is accused of failing to control present invasive species and the consultant needs to provide evidence in court
– The invasive species has spread to neighbouring land and the consultant needs to assess liability and provide testimony
With our evolved application of ecological surveys, Arbtech is perfectly positioned to undertake advanced biosecurity planning and expert witness services. Our team has a proven track record in biosecurity risk management, ecological compliance and legal representation, giving them everything needed to assist developers, landowners and businesses affected by non-native invasive species.
Between creating a farm biosecurity plan to prevent issues with on-site animal health and expert witness services to monitor the ongoing presence of invasive species, our team can step in to guide your development through future stages. After an extensive assessment, we can produce biosecurity measures to deal with any invasive species correctly, and if necessary, continue tracking changes to the site as an expert witness.
We provide all of our services with a free quote beforehand, giving clients an opportunity to see how much the assessment and report will cost before they commit to Arbtech.
