Freshwater Ecologists

The core business of Environmental Impact Assessments is providing advice to councils, consultants, farmers and property developers on water quality and the ecological status of freshwater environments (rivers, streams, lakes and wetlands). Assessment of ecological effects reporting is a requirement for any development near water under the Resource Management Act. We undertake freshwater ecology surveys for clients which forms part of the resource consent application.

Water Quality Assessments

Technicians sort through stream and estuary samples to pick out invertebrate life. The invertebrates are a fundamental component of aquatic ecosystems and are also bio indicators of water quality. The information obtained from each sample is condensed into a biological index of water quality for assessment of ecological effects reporting.

Community Education Advocates

Over the years EIA LTD have been called upon to help with education outside the classroom. We LOVE this work as it provides an opportunity to engage with the community about the importance of preserving stream and wetland ecosystems.

Resource Consent Advice - Water Quailty

If you need resource consent advice for anything surrounding water quality, freshwater ecology, aquatic ecosystems, riparian vegetation, stream gaugings, stream depletion or freshwater biodiversity then please call us. Our operative Health and Safety Plan combined with public liability and professional indemnity insurance gives clients confidence that the risk of potential liabilities are minimised. We have conducted training seminars on environmental data analysis at regional councils.

As a State Owned Enterprise, Landcorp has over 120 farms across New Zealand to administer.  Landcorp (now Pāmu) engaged EIA to assess aquatic resources in and around our Ahuriri Farm, Napier.  The work was undertaken promptly and efficiently, with the resource inventory and statistical analyses undertaken with rigour.  The resulting report provided excellent information for the Resource Management Act decision making.  EIA remain our preferred supplier in this field and their work is trusted by our Iwi and regulatory partners.

We engaged EIA to provide technical support for our freshwater SOE programme, specifically review of and guidance for reporting ecology data to meet NPS-FM requirements. Key deliverables included review of macroinvertebrate metric calculations and analysis of spatial and temporal trends in MCI and SEV data. We found EIA easy to work with, delivering on time and meeting budgetary requirements.
