Full DescriptionAbstract: This package contains vegetation survey data, collected between 2011 and 2018, for 60 0.2 hectare sites which were established on dune crests and upper slopes in Tarawi Nature Reserve; Scotia Sanctuary and Danggali National Park.

Sampling method: Fifty-three experimental sites have been established on dune crests and upper slopes during 1996–2011, of which 29 are located within Tarawi NR, with 16 in Scotia and eight in Danggali NR. In Tarawi NR, each is marked with a steel sign on an adjacent access track. These include four pilot sites established during 1996-1998, during which the design of herbivore exclosures were developed.

Study extent: Between 1996 and 2011, 53 experimental sites were established on dune crests and upper slopes, of which 29 are located in Tarawi Nature Reserve, 16 are in Scotia Sanctuary and 8 are in Danggali Conservation Park. After initial censuses in three consecutive years (before and after prescribed fire) or two consecutive years (after wildfire), sites are revisited approximately every five years.

The study focusses on vegetation dynamics on dune crests and upper slopes, primarily because resources are insufficient to sample across the full catenary sequence of dunes and swales. Study of fire in swale landforms is problematic because these are rarely flammable under prescribed fire conditions due to the absence of hummock grasses, which augment lateral fuel connectivity and thus promote fire spread on the dune crests and slopes.

The study is located in the red aeolian sand dunefield landscape of the Scotia district within Tarawi Nature Reserve (33.44ºS 141.16ºE), Scotia Wildlife Sanctuary (33°17′S 141°05'E) and Danggali Nature Reserve (33° 22' S 140° 45' E) in south-western New South Wales and adjacent area of South Australia. The study area sits on the south-eastern edge of the Australian arid zone.

This location is close to the arid limits of distribution of the mallee woodland biome, which stretches across the temperate semi-arid belt of southern Australia (Noble 1984). Mallee woodlands typically occur within regions receiving 200-500 mm rainfall per year. During 1940-2010, mean annual rainfall at Tarawi Homestead was approximately 240 mm (data summary courtesy of John Warren, Tarawi NR)

Project funding: Between 2012 and 2018 this project was part of, and funded through the Long Term Ecological Research Network (LTERN) a facility within the Terrestrial Ecosystem Research Network (TERN) and supported by the Australian Government through the National Collaborative Research Infrastructure Strategy.

Description
Fifty-three experimental 0.2 hectare sites were established on dune crests and upper slopes in Tarawi Nature Reserve; Scotia Sanctuary and Danggali National Park. This is part of a much larger dataset that spans from 1996 to 2015.

Title
Vegetation Survey - Floristics
Description
The density (number of individuals per unit area) of each vascular plant species are recorded in every plot. Counts of each species are partitioned into: live established plants and live seedlings.
Note:
Chenopodium melanocarpum has a more recent taxonomy of Dysphania melanocarpa, and similarly Eucalyptus costata is now considered synonymous with Eucalyptus incrassate, however these data use their original names so as to maintain consistency with other data packages from the same time series.
There are also taxa which were unidentifiable, however they have been left in the data so that species richness is not underestimated.

Title
Vegetation Survey - Structure
Description
Attributes recording vegetation structure are visually estimated in each of five 15 x 15 m fenced plots and the three 13 x 7.5 m unfenced external plotsexclusion and external plot. These currently include: hummock grass height (ten randomly selected individuals per plot); and single estimates per plot for: tree cover and height range; shrub height (median and range); shrub cover; hummock grass cover; ephemeral grass cover; leaf and twig litter cover and bare ground cover. The estimates made in each plot are aided by informally dividing each plot into segments for logistical purposes only, and then aggregated for the plot.
