Ecological Impact Assessments (EcIA)

Ecological Impact Assessments to Support Resource Consents and Development in Sensitive Environments

What Is an Ecological Impact Assessment (EcIA)?

An Ecological Impact Assessment (EcIA) is a technical report that evaluates the potential effects of a proposed activity or development on ecological values, including indigenous vegetation, habitats, and fauna. EcIAs are commonly required as part of the resource consent process under the Resource Management Act 1991 (RMA), particularly where works are proposed within or adjacent to a Significant Ecological Area (SEA).

Our EcIAs are prepared by suitably qualified and experienced ecologists (SQEP) and are aligned with the Ecological Impact Assessment Guidelines (EIANZ, 2018), ensuring they are robust, defensible, and appropriate for council review.

When Is an EcIA Required?

An EcIA is typically required where a proposal may affect ecological values protected under regional or district planning rules, including the Auckland Unitary Plan (AUP). Common triggers include:

  • Development within a Significant Ecological Area (SEA)
  • Indigenous vegetation removal or modification
  • Earthworks, retaining walls, or building extensions in sensitive environments
  • Infrastructure or access works affecting natural habitats
  • Activities classified as Restricted Discretionary or Discretionary under AUP E15 – Vegetation Management and Biodiversity

We work closely with planners, engineers, and designers to identify ecological constraints early and provide clear guidance on assessment requirements.

Our EcIA Process

Our EcIA process is proportionate, site-specific, and focused on achieving practical outcomes. It typically includes:

  • Desktop review of planning provisions, ecological districts, and mapped overlays
  • Site surveys to identify vegetation types, habitats, and fauna presence
  • Assessment of actual and potential ecological effects
  • Consideration of avoidance, remediation, and mitigation measures
  • Preparation of a clear, consent-ready EcIA report suitable for submission to council

Where required, we also provide input into Assessments of Environmental Effects (AEE) and respond to council requests for further information (RFI).

Significant Ecological Areas and Planning Compliance

We have experience assessing proposals within Significant Ecological Areas and areas subject to vegetation and biodiversity controls. Our assessments explicitly address relevant planning provisions, including Auckland Unitary Plan E15.8.1 and other applicable regional or district rules.

By clearly linking ecological effects to planning criteria, our EcIAs assist decision-makers in understanding the nature and scale of effects and how proposed mitigation achieves positive ecological outcomes.

From Assessment to Implementation

Ecological Impact Assessments are often just the first step. Where consent is granted, we can continue to support projects through:

  • Ecological Management Plans (EMP)
  • Lizard Management Plans (LMP)
  • Construction-phase ecologist supervision
  • Monitoring, reporting, and compliance support
  • Restoration planting and long-term maintenance advice

This end-to-end approach helps ensure ecological outcomes are delivered on the ground, not just on paper.
