Our experience spans biodiversity assessment, arboriculture, vegetation management, environmental approvals, threatened species surveys, project ecologist services and independent peer review. ESEA also undertakes biodiversity peer review work for Councils in the Greater Sydney Region.
We maintain professional indemnity and public liability insurance appropriate to our consultancy services and provide clearly defined, itemised scopes so clients understand what is included and where further work may be required.

From enquiry to proposal
Send us the site address, a description of the proposed works, available plans and any relevant correspondence from council or another approval authority.
We will review the available information and prepare an itemised proposal setting out the next steps forward, required scope, site investigations, reporting stages, meetings and professional fees.
For straightforward enquiries, we typically aim to provide a proposal within two business days. If your project has a fixed approval or construction deadline, let us know at the outset. Threatened species survey periods, authority requirements and the availability of a stable project design can have a greater effect on the overall programme than report preparation itself.
