Evaluation of the morphological variation within the genus <em>Polyosma</em> (<em>Escalloniaceae</em>) of Australia, New Caledonia and Papuasia based on herbarium specimens to clarify the taxonomy of the recognized species in this genus. These data also identified several previously unpublished species that are new to science.

Vertical plant profiles for the Australian continent were derived through integration of ICESat GLAS waveforms with ALOS PALSAR and Landsat data products. Co-registered Landsat Foliage Projected Cover (FPC) and ALOS PALSAR L-band HH and HV mosaics were segmented to generate objects with similar radar backscatter and cover characteristics. Within these, height, cover, age class and L-band backscatter characteristics were summarised based on the ICESat and Landsat time-series and ALOS PALSAR datasets.

Mating system and fitness data for families of <em>Eucalyptus socialis</em> grown in common garden experiments. Families collected across a fragmentation gradient. Open-pollinated progeny arrays were collected and reared in the common garden experiments. These open-pollinated progeny arrays were also genotyped at microsatellite loci to generate the mating system data. Data showed association between fragmentation on mating system, which in turn impacted fitness. Please contact owner prior to use.

<p> The dataset aims at studying associations between mating system parameters and fitness in natural populations of trees. Fifty-eight open-pollinated progeny arrays were collected from trees in three populations. Progeny were planted in a reciprocal transplant trial. Fitness was measured by family establishment rates. We genotyped all trees and their progeny at eight microsatellite loci. Planting site had a strong effect on fitness, but seed provenance and seed provenance × planting site did not. Populations had comparable mating system parameters and were generally outcrossed, experienced low biparental inbreeding and high levels of multiple paternity. As predicted, seed families that had more multiple paternities also had higher fitness, and no fitness-inbreeding correlations were detected. Demonstrating that fitness was most affected by multiple paternities rather than inbreeding, we provide evidence supporting the constrained inbreeding hypothesis; i.e. that multiple paternity may impact on fitness over and above that of inbreeding, particularly for preferentially outcrossing trees at life stages beyond seed development. This dataset could potentially be reused for meta-analysis or review of effects of habitat fragmentation on plants (e.g. pollination, mating system, genetic diversity etc).

Main goals of the project were 1. Examine and quantify the impact of fragmentation and tree density on mating patterns, and how this may vary with pollinators of differing mobility 2. Determine the theoretical expectations and perform empirical tests of mating pattern-fitness relationships in trees 3. Explore the plant genetic resource management implications that arise from the observations in aims 1 and 2 </p>

Seedling surveys were conducted at the Robson Creek Rainforest site between 2010 - 2011. The identity and height of all seedlings were recorded along 98 x 20 m transects.

Destructive sampling of 47 <em>Eucalyptus obliqua</em> trees was carried out in the Warra Tall Eucalypt site to determine a range of biomass measures that can be used to inform allometric equations.

Data were used to demonstrate fitness impacts caused by fragmentation context. Showed extensive pollination can protect tree fitness from fragmentation. Grew open-pollinated progeny arrays of the bird-pollinated, mallee tree <i>Eucalyptus incrassata</i> in a randomised block design in a common garden experiment at Monarto, South Australia. Progeny arrays were collected from parental trees in either continuous forest or highly fragmented contexts. Data are therefore experimental, for hypothesis testing Data are not descriptive ecological, not plot based and not time-series. Data are not a representative sample of <i>Eucalyptus incrassata</i> and not representative of mallee eucalypts.

<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 Belconnen Naval Transmitter Station in ACT, Australia. </br><br> Pre-European benchmark-analogue vegetation: the original vegetation for the site Belconnen Naval Transmitter Station was a temperate grassland in an ecological community dominated by native species of perennial tussock grasses. </br><br> Brief chronology of changes in land use and management:<ul style="list-style-type: disc;"> <li>Up to late 1820s the area was managed by indigenous Ngunnawal people</li> <li>1830s: Area first grazed by sheep and cattle with the aid of shepherds</li> <li>1860: Fences were established and continuous stocking commenced</li> <li>1900: Patches of woodland areas on higher ground were partly cleared</li> <li>1900-39: High likelihood of moderate to heavy grazing pressure due to sheep and cattle</li> <li>1940-1993: Area managed as a naval transmission station</li> <li>1940-92: Area managed for sheep grazing under continuous grazing</li> <li>1970: Secure people and kangaroo proof fence established</li> <li>1993: Sheep removed from the site</li> <li>1995: mowers used to manage the grass</li> <li>1997-2008: Kangaroo population increased to unacceptable levels</li> <li>2006: Naval transmission towers demolished, area continued to have a secure people proof fence</li> <li>2008: Kangaroo population culled to reduce grazing pressure</li> <li>2011: Site managed for nature conservation values.</li></ul></br>

Seedling surveys were conducted at the Samford-Peri-Urban site between 2012 - 2018. The identity and height of all seedlings were recorded along six transects.

Seedling surveys were conducted at the Tumbarumba Wet Eucalypt site in 2015. The identity and height of all seedlings were recorded along six 20 m x 1 m transects in the core 1 ha plot.
