    This data contains diameter, length volume, biomass and carbon measurements of all coarse woody debris pieces within the core 1 ha plot at the Warra Tall Eucalypt site in 2015.

    <p>Tree structural characteristics are collected at the centre of a site, usually in conjunction with the Statewide Landcover and Trees Study (SLATS) star transect field data. The basal wedge is first used to identify a sample of trees then direct measurements are taken of each tree, which constitute the tree structural characteristics.Tree structural measurements have been collected at several locations across Australia (including the formally known AusCover Supersites) to relate field-based measurements to satellite data products, such as Landsat-derived ground cover estimates.</p> <p>Data can be downloaded from https://field.jrsrp.com/ by selecting the combination Field and Tree Structure.</p>

    This dataset presents the demographic monitoring (growth and survival) of 81 tree species based on repeated stem measurement data from 20, 0.5 ha (100 m x 50 m) permanent moist forest plots in northern Queensland, Australia from 1971 to 2019, as well as four additional plots of 0.1 to 1 ha whose monitoring began in the 2000s. The plots have a rainfall range of 1200 to over 6000 mm, represent eleven vegetation types, six parent materials, and range from 15 m to 1500 m above sea level. Except for minor disturbances associated with selective logging on two plots, the plots were established in old growth forest and all plots have thereafter been protected. Plots were regularly censused and at each census the diameter at breast height (DBH) of all stems ≥10 cm DBH were recorded. We only report the data for the 81 species studied in Bauman et al. 2022 (Nature), here. We also provide the climatology of these plots as well as the temperature, vapour pressure deficit, and maximum climatological water deficit of all intervals separating consecutive censuses, as used in the analyses of Bauman et al. 2022.

    This data contains stem diameter, height measurement and above ground living and dead woody biomass calculations for a remnant Eucalyptus Wandoo woodland from 2018 - present. Diameter and height measurements for stems were sampled within the core 1 ha plot within the Boyagin Wandoo Woodlands site.

    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>Field measurements were made on the 5<sup>th</sup> September 2000 along a 90 m long transect for a section of mangroves located between the beach and main road just north of Cape Tribulation (Queensland).</p> <p>The transect was 90 m long and 10 m wide. The start and end points for the transect were measured using a hand-held GPS. Since tree cover reduced the GPS signal at the start and end points, GPS measurements were taken near the start and end points of the transect using the GPS (where the canopy was more open), then a distance and bearing made to the end points. For trees within the transect area having a circumference at breast height (CBH) greater than 15 cm, their location, CBH and an estimate of height were measured. Only the location was recorded for trees having a CBH below 15 cm (equivalent to a diameter at breast height (DBH) < 5cm). Tree height was measured <em>ad libitum</em> with a hand-held laser system. Mangrove species was also recorded when known.</p>

    The dataset includes two main components: (1) Tree survey - data on the species, diameter and height of individual trees, along with a count of seedlings and saplings; and (2) Coarse woody debris - data on the size and decay class of downed coarse woody debris encountered in the plots.

    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.

    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.

    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.
