Analysing samples for environmental monitoring

Cawthron provides extensive marine and freshwater taxonomy services and is a recognised leader in macroinvertebrate identification for environmental monitoring.

Macroinvertebrates are used as bio-indicators to understand how human activities impact aquatic environments. Studying these species and their communities also helps predict the longer term effects of changes to their environment.

Our taxonomy scientists and technicians are highly experienced with identification and ecology of New Zealand and overseas fauna for monitoring, biosecurity and offshore activities including the oil and gas, and aquaculture sectors.

Our capability in this area includes:

  • Taxonomy services for environmental assessment, consents and permits 
  • Marine and estuarine fauna 
  • Freshwater fauna
  • Molecular tools and analysis 
  • Research 
  • Industry training

Our Taxonomy Laboratory offers:

  • Specialist expertise in invertebrate taxonomy, particularly New Zealand marine benthic invertebrate macrofauna, phytoplankton and zooplankton
  • Extensive experience responding to environmental assessment, consents and permit requirements
  • Quality assurance work and peer reviews
  • Extensive laboratory capability including photo microscopy and large scale sample data entry
  • An extensive marine and freshwater species reference collection
  • A focus on professionalism, accuracy and fast turn-around of results
  • Separate safe and secure facilities for storing samples

Along with our client-driven projects, our Taxonomy Team is also collaborating on independent research and industry development projects to extend taxonomic capability in New Zealand, and support a greater understanding of macroinvertebrate communities in New Zealand and around the world.

Who we work with:

  • Government agencies
  • Regional and local body councils
  • Primary industries including oil and gas, and aquaculture
  • Research organisations 
  • Environmental consultancies
