Flora and Vegetation Surveys

A flora and vegetation survey provides a detailed assessment of the plant communities and individual plant species on your development site. Queensland Ecologists conducts systematic vegetation surveys across South East Queensland, delivering the accurate mapping and classification data that councils and state agencies require for development applications, vegetation clearing permits, and Property Map of Assessable Vegetation (PMAV) applications.

What Is a Flora and Vegetation Survey?

A flora and vegetation survey is a systematic ecological assessment that identifies, maps, and classifies the vegetation on a site. In Queensland, vegetation is classified into regional ecosystems (REs) - standardised vegetation types mapped and described by the Queensland Herbarium. Each regional ecosystem has a conservation status (endangered, of concern, or least concern) that directly affects what you can and cannot do on your land.

A fit-for-purpose flora and vegetation survey typically includes the following components:

• Regional ecosystem (RE) identification and mapping - field verification of state-mapped regional ecosystems, including any unmapped remnant or regrowth vegetation, with polygons mapped to cadastral accuracy
• Vegetation condition assessment - assessment of vegetation condition using the Queensland Government’s BioCondition assessment framework, which scores attributes such as tree canopy cover, native species richness, weed cover, coarse woody debris, and native ground cover
• Threatened plant species surveys - targeted surveys for plants listed as Endangered, Vulnerable, or Near Threatened (EVNT) under the Nature Conservation Act 1992 and the EPBC Act 1999
• Weed mapping - identification and mapping of declared weed species and other invasive plants, noting density and distribution across the site
• Vegetation community structure - description of canopy, sub-canopy, shrub, ground layer, and emergent species to characterise the vegetation type and ecological function

The survey follows the methodology prescribed by the Queensland Herbarium for regional ecosystem identification, using standardised plot-based assessments (secondary and tertiary survey sites) to collect the data needed for accurate classification.

When Do You Need a Flora and Vegetation Survey?

Flora and vegetation surveys are required in a range of planning and regulatory scenarios across Queensland:

• Development in mapped vegetation areas - if your site contains or is adjacent to remnant or regulated regrowth vegetation, most council planning schemes require a vegetation assessment as part of your development application. This applies under environmental significance overlays and vegetation management overlays.
• Vegetation clearing applications - applications under the Vegetation Management Act 1999 for clearing of remnant or high-value regrowth vegetation require a detailed vegetation survey to classify the regional ecosystems affected and demonstrate that clearing can be justified.
• PMAV (Property Map of Assessable Vegetation) applications - if you believe state vegetation mapping is inaccurate for your property, a flora survey provides the evidence needed to apply for a PMAV amendment with the Department of Resources.
• SDAP State Code 8 (native vegetation clearing) - where development triggers state assessment under this code, a vegetation survey is essential to identify conservation-significant regional ecosystems and assess impacts.
• Environmental offset calculations - accurate vegetation mapping and condition assessment (BioCondition) is fundamental to calculating offset requirements under the Queensland Environmental Offsets Framework.
• Protected plant surveys - where the Flora Survey Trigger Map indicates the potential presence of protected plants, a vegetation survey forms the basis for the more targeted protected plant flora survey.

Our Flora and Vegetation Survey Process

Queensland Ecologists follows a rigorous, repeatable methodology that meets the standards expected by Queensland councils and state agencies:

1. Desktop review - we analyse state vegetation mapping (RE mapping version 12+), the Vegetation Management Support Tool, PMAV status, aerial imagery, topographic data, and WildNet records to identify likely vegetation types and species of concern.
2. Survey design - based on the desktop review and site size, we determine the number and placement of vegetation survey plots, ensuring adequate coverage of all vegetation communities present on the site.
3. Field survey - our botanists conduct plot-based vegetation assessments using Queensland Herbarium methodology, recording species composition (all strata), canopy height and cover, soil type, landscape position, and other diagnostic attributes for regional ecosystem identification.
4. BioCondition assessment - at representative sites, we conduct full BioCondition assessments, scoring vegetation condition against benchmarks for the relevant regional ecosystem. This standardised scoring is often required for offset calculations and impact assessment.
5. Mapping and analysis - vegetation polygons are mapped in GIS, regional ecosystems are classified, and conservation status is assigned based on current biodiversity status listings. We provide clear maps showing RE boundaries, vegetation condition classes, and threatened species records.
6. Reporting - a detailed report is prepared including species lists, RE descriptions, vegetation maps, BioCondition scores, and assessment against relevant planning scheme codes and state legislation.

Which Councils Require This?

All SEQ councils require flora and vegetation surveys for development applications that affect mapped vegetation. The specific overlay names and code requirements differ, but the core requirement applies across:

• Brisbane City Council - Significant Vegetation and Natural Areas, Environmental Significance overlay
• Gold Coast City Council - Conservation Significance overlay, Vegetation Management overlay
• Sunshine Coast Council - Environmental Significance overlay, Biodiversity Areas overlay
• Moreton Bay Regional Council - Environmental Significance overlay
• Logan City Council - Environmental Significance overlay
• Redland City Council - Environmental Significance overlay, Habitat Protection overlay
• Ipswich City Council - Environmental Significance overlay
• Noosa Shire Council - Environment and Biodiversity overlay
• Scenic Rim Regional Council - Environmental Significance overlay
