This data contains relative species cover of vascular plants in plots of either mature tall, wet eucalypt forest or of 25-50 year-old silvicultural regeneration following clearfell harvesting in the Warra Tall Eucalypt site between 2010 - 2011

We selected nine study sites, each incorporating three vegetation states: (a) fallow cropland, representing the restoration starting point, (b) planted old field (actively restored site), and (c) reference York gum (E. loxophleba) woodland. Plant species richness and cover All annual and perennial plant species were recorded in spring 2017 within each plot and identified to genus and species level where possible. Nomenclatures follow the Western Australian Herbarium (2017). A point intercept method previously demonstrated to provide objective and repeatable measures of cover (Godínez-Alvarez, Herrick, Mattocks, Toledo & Van Zee 2009; Prober, Standish & Wiehl 2011) was used to quantify cover of individual plant species, total vegetation cover and substrate types (i.e., bare ground, litter cover, plant cover). Ground cover, individual species, and canopy cover intercepting at every 2 m along four parallel, evenly spaced 50 m transects across each plot were recorded using a vertically placed dowel (8 mm wide, 2 m tall), resulting in 100 intercepting points per plot. For planted old fields, transects were placed parallel to planting rows, with two centred on rows and two centred between rows. This approximately represented the relative abundance of planted rows and non-planted inter-rows. If a species was recorded in the plot but did not intercept the dowel on any transect it was assigned 0.5 points. This method provided a measure of relative abundance (percentage cover) of plant species across the plot. To calculate species richness and cover across different life history and growth forms, species were classified into the following groups: total, native trees, native shrubs, native non – planted shrubs, native grasses, native perennial forbs, native annual forbs, exotic grasses and exotic annual forbs using the Western Australian Herbarium (2017) classification. Woody debris and leaf litter surveys Leaf-litter dry mass was estimated by collecting leaf-litter from five randomly placed 25 cm x 25 cm quadrats along two 50 m transects across each plot. Litter was stored in paper bags for transportation and then oven dried for 36 hours at 60 °C. The dried litter was weighed to 3 decimal points. Cover of fine and coarse woody debris and litter depth was estimated at every meter along two 20 m transects for each plot. Woody debris was classified by diameter. Length, max and min diameter was measured for all logs with a diameter greater than 10 cm.

The lesser hairyfooted dunnart (<i>Sminthopsis youngsoni, Dasyuridae</i>) is a generalist marsupial insectivore in arid Australia, but consumes wolf spiders (<i>Lycosa spp., Lycosidae</i>) disproportionately often relative to their availability. This project tested the hypothesis that this disproportionate predation is a product of frequent encounter rates between the interactants due to high overlap in their diets and use of space and time. This data set focuses on overlap in the use of different microhabitats of wolf spiders (<i>Lycosa spp.</i>) and the lesser hairyfooted dunnart (<i>Sminthopsis youngsoni</i>) in the Simpson Desert, southwestern Queensland Australia. Microhabitat use was determined by estimating the percentage cover of seven microhabitat variables and distance to nearest cover along trails left by individuals of each species group and a randomly orientated (control) trail for each actual trail as a measure of the availability of each microhabitat within the local environment. Trail length was also recorded and data was collected across 16 trapping grids at Main Camp during July and October (winter and Spring) in 2017. Differences in microhabitat use between trail types (actual vs control) and species (lycosids vs dunnarts) were assessed using nonmetric multidimensional scaling (NMDS) and permutational analyses of variance (PERMANOVA). These analyses were performed using this data.

<br>The aim of this project is to compile land use and management practices and their observed and measured impacts and effects on vegetation condition. The results provide land managers and researchers with a tool for reporting and monitoring spatial and temporal transformations of Australia’s native vegetated landscapes due to changes in land use and management practices. Following are the details about South Brooman State Forest, NSW. </br><br> Pre-European reference-analogue vegetation: The site was originally eucalypt tall open forest, multi-aged open, dry sclerophyll forest. The main overstorey species were spotted gum (<em>Corymbia maculata</em>), <em>Eucalyptus muelleriana</em>, <em>E. paniculata</em>, <em>E. pilularis</em>. The main understorey species were <em>Acacia spp.</em>, <em>Acmena spp.</em> </br><br> Brief chronology of changes in land use and management:<ul style="list-style-type: disc;"> <li>1830: Unmodified</li> <li>1880: Area picked over for high quality sawlogs</li> <li>1945: Area picked over for high quality sawlogs</li> <li>1949: Sawlog harvesting - 85% of area</li> <li>1959: Sawlog harvesting - 85% of area</li> <li>1968: Commercial Thinning - 25% of area</li> <li>1969: Area left to rehabilitate</li> <li>1994: Wildfire - 100% of the area</li> <li>1996: Pole harvesting - 5% of area</li> <li>1998: Sawlog harvesting - 20% of the area</li> <li>1999 and 2003: Hazard reduction</li> <li>1997: Site was burnt (prescribed fire) followed by drought</li> <li>2004-2011: Area left to rehabilitate</li></ul></br>
