Ecological services and ecology consulting that fit within broader environmental and project approvals advice.
Where ecological constraints intersect with planning, development or broader environmental management, iEnvi helps clients bring ecological services into the decision process without losing sight of programme, site use or stakeholder requirements.
What clients usually need from ecological services and ecology consulting advice.
The layout keeps the service story balanced: typical triggers, practical outputs and the working style clients can expect from iEnvi.
When clients usually call
- Development sites with ecological sensitivities or approval constraints.
- Projects needing coordinated advice across contamination, environmental management and ecology.
- Stakeholder matters where site constraints must be explained clearly and practically.
Outputs that support decisions
- Ecological advice and targeted project support.
- Coordination with broader environmental approvals and management requirements.
- Clear communication on how ecological issues affect timing, design and delivery decisions.
Working style
- Ecology treated as part of the project picture, not a disconnected add-on.
- Advice framed around approvals, land use and implementation.
- Senior review with access to specialist input where the project demands it.

Common Questions
When do I need an ecological assessment for a development?
An ecological assessment is typically required when a development site contains or adjoins native vegetation, waterways, wetlands, or habitat for listed species. Council or state planning requirements will usually trigger this during a development application. In Queensland, koala habitat mapping, regulated vegetation, and waterway setback provisions commonly require ecological input. In NSW, the Biodiversity Offsets Scheme applies to larger or more sensitive sites. Early screening can confirm whether formal assessment is needed.
What does an ecological assessment involve?
A typical assessment includes a desktop review of government mapping and databases, a site inspection to ground-truth vegetation and habitat values, species-specific surveys where required, and a report that addresses the relevant legislation and planning conditions. For larger projects, this may extend to biodiversity development assessment reports (BDARs), offset calculations, and referral documentation for matters of national environmental significance under the EPBC Act.
How long does an ecological assessment take?
A standard assessment for a development site can typically be completed within 2–4 weeks, depending on site complexity and survey requirements. Some species-specific surveys are season-dependent and may need to be timed to particular months. Where offsets or referrals are involved, the overall process can extend to several months. We advise on timing constraints early so they do not hold up the broader programme.
