Where this comes from

Every figure is fetched live from the Victorian Government’s open spatial data service (opendata.maps.vic.gov.au), which carries DEECA’s datasets. Tolerable fire intervals and growth stages come from Cheal (2010), the source of DEECA’s tolerable fire interval and growth stage tables; for the vegetation types in the guide’s Part 1 tables they are the same figures. Each EVC is matched to one of DEECA’s Ecological Fire Groups by its EVC number, following Cheal (2010).

• Bioregions: Victorian Bioregions (VBIOREG100)
• Geology: Seamless Geology 1:250,000 (GEOL250)
• Vegetation: 2005 and pre-1750 Ecological Vegetation Classes with Bioregional Conservation Status (NV2005_EVCBCS, NV1750_EVCBCS)
• Fire groups and intervals: Cheal, D. (2010) Growth stages and tolerable fire intervals for Victoria’s native vegetation data sets. Fire and Adaptive Management Report 84, DSE (Table 2.5 and Section 4)
• Fire: Fire History Records of Fires across Victoria and Fire History showing the number of times areas have been burnt
• Plants: Victorian Biodiversity Atlas flora quadrat records (VBA_FLORA25), pre-summarised by bioregion and vegetation type; fire traits from AusTraits 7.0.0, mainly DEECA’s Vital Attributes database (White 2020) and Cheal (2017); photos loaded live from iNaturalist, credited on each image.
• Property boundaries: Vicmap Property. Catchment Management Authority and Landcare group boundaries (Landcare groups as mapped in 2015).

All of these are drawn at a landscape scale and can be wrong for a single property. If what you see on the ground disagrees, trust your eyes and talk to your Landcare group.
