East Kimberley vegetation structure

The Vegetation Structure classes dataset was derived from Vegetation Height Model (VHM) and Fractional Cover Model (FCM) LiDAR products. The National Vegetation Information System framework was used to classify vegetation height and canopy/cover density into (sub-)stratum, growth forms, and structural formation classes. The classifications contain descriptions and spatial extents of the vegetation types for the East Kimberley LiDAR survey area. The displayed classifications include 19 dominant structural formation classes, and 43 dominant sub-structural formation classes for lower-, mid-, and upper stratum.

High resolution LiDAR imagery, including Digital Elevation Model (DEM), Canopy Height Model (CHM), Vegetation Height Model (VHM), Vegetation Cover Model (VCM) and Fractional Cover Model (FCM) surfaces were acquired for the East Kimberley area in June 2017. All the data were released in 2019 (Geoscience Australia, 2019).

For the purposes of vegetation structure mapping, the two input datasets were resampled, classified and combined to produce a vegetation structure map for the East Kimberley area. The methods are described by Lawrie et al. (2012), with the following differences:

• resampling used Focal Statistic Min in ArcGIS as it more accurately represented vegetation extent

• VHM was used instead of CHM as CHM did not include low vegetation (i.e ground cover).

• VHM and FCM were classified into height and foliage cover classes using the Australian Vegetation Attribute Manual (NVIS Technical Working Group, 2017).

Authors acknowledge the tremendous work of the Geoscience Australia Elevation team who carried out post processing, classification, production, quality assurance and delivery of all released LiDAR data products (see Geoscience Australia, 2019). In particular, the authors thank Graham Hammond, Kevin Kennedy, Jonathan Weales, Grahaem Chiles, Robert Kay, Shane Crossman, and Simon Costelloe.

Statement: Both VHM and FCM were resampled to 5 m using Focal Statistic Min in ArcGIS, from their original spatial resolution of 2 m and 10 m respectively. The VHM was classified into 8 height classes and associated growth forms, (sub-) stratum codes and descriptions, and structural formation classes using the National Vegetation Information System (NVIS) Australian Vegetation Attribution Manual (NVIS Technical Working Group, 2017). FCM derived from LiDAR provides a percentage foliage cover for each 10 m cell. Foliage cover was defined for each stratum as 'the proportion of the ground, which would be shaded if sunshine came from directly overhead' and includes branches and leaves. The Fractional Cover Model (FCM) was converted to 7 foliage cover classes with corresponding cover code information (e.g. open, sparse, etc; see NVIS Technical Working Group, 2017). The 8 VHM and 7 FCM classes were then combined into 19 structural classes within Upper, Mid and Lower stratum, and 43 sub-stratum structural classes, further subdivided into higher (1), mid (2), and lower (3) sub-stratums (see NVIS Technical Working Group, 2017).
