The services we offer include:

  • Assessments of risk and impact to identify and priorities the effectiveness of measures
  • Monitoring and surveillance using an array of methods
  • Biosecurity management plan development and testing of measures
  • Control and eradication programmes development and delivery
  • Advice based on the best available evidence to support management actions

Invasive and non-native species (INNS) or Alien Invasive Species (IAS) are one of the greatest drivers of biodiversity loss, can affect human health, and impact on natural capital and ecosystem services, resulting in a combined estimated annual cost to the UK of £1.7 billion per annum. In response there are Increasing regulatory requirements being implemented globally to more effectively manage this growing issue.

We have extensive experience, with internationally recognised experts, providing our services to a broad range of clients, including government bodies, port authorities and water companies, tackling a diverse range of INNS related issues. Our expert team takes a multi-disciplinary approach in providing a range of bespoke services to our clients.

Identification of invasive non-native species

Among APEM’s staff are scientists who are nationally and internationally known in the field of invasive species and who have created identification guides and risk assessments.

They have been instrumental in first identifying several marine and freshwater invasive non-native species new to the UK, including demon shrimp (Dikerogammarus haemobaphes), migrant prawn (Palaemon macrodactylus), the polychaete worm (Hypania invalida) and quagga mussel (Dreissena rostriformis).

Our experts have helped to publicise the presence of these species and produce identification materials.

Monitoring and surveillance

Our scientists are internationally recognised in the field of INNS detection and identification. APEM’s specialists have an in-depth understanding of a broad range of survey and monitoring methods, including type-specific and novel methods such as aerial remote sensing for riparian plants and ballast water analysis. We also have experts in house who can provide advice on eDNA sampling, analysis and interpretation.

APEM offers bespoke monitoring programme design and delivery services to meet our clients’ needs. Our staff have been instrumental in first identifying several marine and freshwater INNS new to the UK and Ireland, including demon shrimp (Dikerogammarus haemobaphes), migrant prawn (Palaemon macrodactylus), the polychaete worm (Hypania invalida) and quagga mussel (Dreissena rostriformis).

Assessment of risks

APEM has extensive experience of conducting assessments to aid in prioritisation and decision making. We have assessed risk of introduction and spread of INNS for discreet locations (e.g. SROs and ports), of specific pathways (such as raw water transfers), and at the species level. With our natural capital experts, we are able to assess impact on ecosystem services to aid in prioritisation and decision making. We have a range of tool kits and methodologies specifically designed for assessing INNS related risks and informing the development of options appraisals and biosecurity plans.

Biosecurity

We provide expert advice on efficient and cost-effective biosecurity measures aimed to reduce the risk of introduction and spread from occurring. We examine both existing and novel approaches and have produced biosecurity plans for a range of sites and activities, such as port and marinas, water transfers and recreational activities.

Control and eradication

APEM designs and delivers control and eradication programmes for populations of INNS. We use evidence provided by our assessment and monitoring services to inform the development of programmes to increase chances of success.

Bespoke services

With our combination of technical specialists and non-native and invasive species experts we are able to provide a bespoke service, either as a whole management programme covering monitoring, assessments, biosecurity, control, advice and delivery, or individual elements depending on the clients needs. We can also provide training and presentations at any level on all aspects of non-native and invasive species management.
