Full DescriptionAbstract: The Victorian Tall Eucalypt Forest Plot Network Vegetation Survey Data contains transect, plot- and subplot-based vegetation data collected from 175 sites spread across the montane ash forests of the Central Highlands in Victoria, Australia between 2012 and 2016.

This is part of a much larger dataset that began in 1983, when the Victorian Tall Eucalypt Forest Plot Network research plots commenced. Vegetation related data is collected annually from 105 of 175 sites (mainly sites burnt in 2009) and every 2 to 3 years from the remaining 70 sites (unburnt sites).

Vegetation species are recorded along transects. A Height versus Diameter matrix is used to record all woody plants and tree ferns over 2m in height within the three 10 x 10 m plots situated along the transect. A basal sweep is done in the middle of each 10 x 10 m plot. Basal Area Factor 1m squared is used with the number of Acacia species recorded, as well as whether the tree is alive or dead. Seedling plots (1mx1m) are located in the middle of each of the three 10mx10m plots and all living plant species which are less than 5 m in height with their bases rooted within the 1 x 1 m plots are recorded by height increments in the table.

Sampling method: Each long term monitoring site is 3 hectares. Vegetation data is collected annually, but not all plots are surveyed every year. The majority subset (60% - and the same subset each year) are surveyed annually, the remainder are surveyed every 2-3 years. The annual survey sites are those that were burnt in 2009, plus a few extras. The less frequently surveyed sites are the long unburnt/green sites that have less annual change.

Study extent: Each monitoring site is 3 hectares, with monitoring occurring only on the central hectare which is usually square, measuring 100m x 100m or occasionally sites measuring 200m x 50m where they interface gullies. Please refer to "Geographic Coverage", "Taxonomic Coverage and Classification", and "Temporal Coverage" for further details.

Project funding: Between 2012 and 2018 this project was part of the Long Term Ecological Research Network (LTERN). This work was supported by the Australian Government’s Terrestrial Ecosystems Research Network (www.tern.org.au) – an Australian research infrastructure facility established under the National Collaborative Research Infrastructure Strategy and Education Infrastructure Fund–Super Science Initiative through the Department of Industry, Innovation, Science, Research and Tertiary Education.

Other funding agencies supporting this research project for various periods include: Parks Victoria (2004-2019); Victorian Department of Natural Resources and Environment (2004-2005); Victorian Department of Sustainability and Environment (2006-2011); Thomas Foundation (2009); Australian Research Council Discovery Program DP1097170 (2010-2015); National Environmental Research Program, Environmental Decisions Hub (2011-2014); Victorian Department of Environment and Primary Industries (2014-2018); Graeme Wood Foundation (2015-2017); and National Environmental Science Program, Threatened Species Recovery Hub (2015-2020)

Title
Plot set-up
Description
Vegetation survey data was collected on all 175 permanent 1ha sites in the Victorian Tall Eucalypt Forest study every 2nd or 3rd year. In the other years, all burned sites plus a sample of unburned sites were surveyed.
Instrument
Basal wedge, laser rangefinder, DBH tape, plot marker pins.

Title
Vegetation Surveys
Description
Each 1 ha site (100m x 100m) had a central transect bisecting the site from the middle of the front edge to the middle of the rear edge. Along the transect were three plots (10m x 10m), located between 10m-20m, 50m-60m and 90m-100m each plot bisected by the transect. In the centre of each plot was a 1m x 1m seedling subplot.
Species diversity:
A record is taken whenever a species is observed within 5m either side of the central transect (marked ‘T’) and additionally if the species is seen within any of the three 10x10 m plots a ‘1’, ‘2’ or ‘3’ are additionally listed in the box next to the species. (Example “T/1/3 Acacia dealbata” would mean A.dealbata. was seen in plot 1 and plot 3 and on the transect). If a species is seen only within a 10x10 m plot, it is still recorded on the transect as the transect includes the three plots. If a species is identifiable but dead, it is not recorded. Immediately post fire, species were recorded as live, dead, or burnt. If a species is associated only with the roadside vegetation, the species is marked ‘R’. If the species is only observed elsewhere on the site outside the 10 x 100 m transect, it is listed with a diagonal slash across the box or ‘S’ to indicate it is present elsewhere on the site.
Height v Diameter matrix:
The Height v Diameter matrix records all the woody plants and tree ferns (no grasses, bracken, sedges, climbers etc.) over 2 m within the three 10x10 m plots. Every stem has Diameter at Breast Height (DBH) and overall height measured and the species is entered in the matrix. Multiple stemmed plants generally have a count for each individual stem over 1.3m high (the height at which DBH is measured), so a single Correa or Olearia plant (for example) may be counted as multiple stems. Tree ferns with fronds that extend above 2 m are recorded in the diameter class of their trunk, even if this is below 1.3 m high. Tree ferns with trunks shorter than 1.3 m are still recorded as a single occurrence.
Stems are listed as either alive ‘L’, or dead ‘D’. For example “Adx3 (D)” denotes three dead Acacia dealbata.
The Height v Diameter matrix originally was a single table for each site, with all three plots entered into the one table. In 2012, this was split into three individual tables, one for each 10 x 10 m plot to help with identifying change over time.
Basal wedge of Acacia:
A basal sweep is done in the middle of each 10 x 10 m plot, using the “bottle opener” type basal wedge, using the ‘BAF 1’ slot. The number of each species of Acacia is recorded, as well as whether the tree is alive or dead. Trees shorter than 2 m are not counted. Trees on a lean greater than 45 degrees are not counted.
Seedling plots:
All species that are rooted within the 1m x 1m plots (usually located in the centre of the 10m x 10m plots), and are alive, are recorded by height increments in the table. Where the species is a sprawling ground cover (e.g. Stellaria, wire grass, geranium etc.), an estimate of rooting nodes is taken.
Instrument
Basal wedge, laser rangefinder, DBH tape.
