Growth Stage Structure status of Vegetation on public land
dataset:
FIREECOL_STATUS_GSS
This layer shows the modelled Growth Stage Structure (GSS) status of vegetation on Victorian public land between years 2002 and 2015. Vegetation GSS relates to the stages of vegetation succession. The GSS status of vegetation depends on when it was last burnt.
For a full understanding of the concepts on which this dataset is based, please see DSE Fire and adaptive management report no. 84, "Growth stages and tolerable fire intervals for Victoria's native vegetation data sets", David Cheal, 2010.
The dataset categorises the landscape into six categories: Juvenile; Adolescent; Mature; Old; Public land with no recorded fire history; and Private land. The four growth stages are a simplification from those provided in Cheal (2010) and encompass these groupings:
(1) Juvenile (Renewal, Juvenility, Founding) - from immediate post-fire renewal to establishment, including the period before which the full floristic complement of species is reproductive
(1) Adolescent (Adolescence) - the vegetation is relatively young, and the full complement of species is reproductive, but not at the rate characterising mature vegetation
(3) Mature (Early Maturity, Maturity, Vigorous Maturity, Stasis, Established) - including when dominant species are fully reproductive through to stasis, when vegetation structure and reproductive capacity stabilise
(4) Old (Waning, Senescence) - characterised by declining reproduction of the dominant species and decreasing propagule banks; if left undisturbed, vegetation may become senescent and is then unlikely to be reconstituted following fire.
The layer was created by the Fire and Emergency Management Division in the Department of Environment, Land, Water and Planning, and completed September 30th 2015.

Description
- Title
- Growth Stage Structure status of Vegetation on public land
- Alternate title
- FIREECOL_STATUS_GSS
- Purpose
- FIRE_ECOL_STATUS_GSS is used in annual reporting on changes in GSS status of Victorian public land. The layer also provides the base data for several fire ecology analytical and planning processes.

Lineage
- Statement
- Dataset Source: The FIRE_ECOL_STATUS_GSS layer is created annually based on the FIRE_HISTORY layer, the FIRE_ECOL_EFGEVD layer, and a tolerable fire interval by EFG look up table [EFG_EVD_GSS (NOV 2011).csv]. Initial GSSs were determined for each EVD as part of a research project undertaken in 2010. See DSE Fire and adaptive management report no. 84, "Growth stages and tolerable fire intervals for Victoria's native vegetation data sets", David Cheal, 2010. GSSs were determined based on published data, field observations and the data in the Vital Attributes database. The growth stage classes provided by Cheal (2010) have since been simplified to four growth stages. Dataset Originality: Derived

- Comments
- Refer to FIRE_ECOL_EFGEVD and FIRE_HISTORY. The simplification of the growth stage classes provided by Cheal (2010) into four growth stages resulted in a loss of precision associated with the fire response characteristics of each EFG. The simplification was based on expert judgment. For a full description of the method used, see the Unpublished Client Report "Initial Growth Stage Optimisation Analyses in the Otways Building the Ecosystem Resilience Model for Adaptive Fire Management and Planning," J. MacHunter, M. Baker, A. Blackett, T. Gazzard and G. Friend (2015).

Missing Data
- Comments
- Wildfires information has been collected for the East Gippsland old-growth study area. The dataset for the central highlands is essentially complete, however no new records beyond 1993 have been recorded. The datasets for the North East and Goldfileds areas are currently being compiled. Vegetation on public land in Victoria
