Gentry transects were established to monitor the vegetation abundance, cover and structure of the mid-stratum and subordinate stratum of the core 1 ha plot in the Warra Tall Eucalypt site in 2014.

Thanks to Ms Lisa Guia, who undertook the Gentry Transect survey as a third year student project as part of an undergraduate degree in the School of Biological Sciences, University of Tasmania.
Lineage
Gentry surveys were conducted using the methodology outline in theTERN vegetation monitoring protocols.
Mid-Stratum Gentry survey
All mid-stratum woody plants (≥ 1.5 m tall and <10 cm DBH) within 1m either side of the centre-line of the 50 m transect were identified to species; their height, diameter at breast height (DBH) and crown width measured; and their position in the 50 x 2 m transect recorded.
Sub-Stratum Gentry survey
Subordinate stratum survey was done in a 20 m x 1 m section of each 50 x 2 m transect. All woody plants in the subordinate stratum (<1.5 m but >0.1 m tall) were labelled; and their taxon, height and position on the 50 x 2m transect recorded. 1 x 1 m quadrats spaced every 5 m along each 50 m transect (the plots were positioned on the left hand side of the centreline – facing the end-point of the transect). In each 1 x 1 m quadrat: (i) were; percent total cover of grasses, ferns and shrubs were visually assessed; percent cover of the dominant species of grass, fern and shrub was visually assessed.
