<p>In 1997, many very young <em>Senna</em> seedlings were noticed in the Cassia corner and outside the northern boundary fence. To study the effects of grazing on these seedlings outside the reserve, three populations were identified and measured to the north of the fence, and a fourth population just south of the fence in the Reserve, not otherwise enclosed. </p> <p>Two of the outside populations were enclosed in triangular fences, one with sheep netting to protect from grazing by sheep, the other with both sheep and rabbit netting to protect against both sheep and rabbits. A third population was left unprotected. The population inside the Reserve was assumed to be protected from all grazing by the Reserve fence. The aim was to follow the fates of the original cohort. </p> <p>This is version 2.0 of the Koonamore Senna Population data release.</p>

In 1955, some young <em>Myoporum</em> seedlings were located in the reserve and it was decided to measure and record their progress. The plants are individually labelled with metal tags and given a unique alphanumeric identity. <br></br> On each occasion, species ID, height, crown diameter N-S, crown diameter E-W, basal circumference, and comments on tree health are noted. The geolocation of each individual is recorded. Most of the records range from 1975 – 2011 with a maximum of 21 measurements between those years.<br></br> This is version 2.0 of the Koonamore <em>Myoporum</em> individuals data release and supersedes any previous versions.

<p>This record is a collection of photopoints from surveys conducted in the TGB Osborn Vegetation Reserve (or Koonamore Vegetation Reserve (KVR)) since the early 1900s. Photographs have been taken approximately annually from 1926 until 2024 at a series of set positions (photopoints) by staff and students of the University of Adelaide. The duration of the record available digitally extends from 1907 (observations) to 2008 (photographs). These include stand-alone positions, corners of quadrats and points along transects. Photographs may have been taken in more than one direction at each point, and/or in black and white or colour. Each photograph was annotated according to what could be seen on the photograph, individual species identified, numbers given to each plant (not always reliable from event to event). Occasionally information on canopy diameter measured along EW and NS direction, plant height and plant mortality status is presented.</p> This is version 2.0 of the Koonamore photopoint data release and supersedes any previous versions.

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 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.

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.

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^th 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>

<p>There are data from 30 quadrats in the TGB Osborn Vegetation Reserve, varying in size and duration of measurements, several of which are shown in the Reserve map. They range in size from large quadrats (100 x100 m), one 60 x80m, to intermediate (10 x10 m) and small (1x1m and irregular). Most quadrats are inside the reserve but some lie adjacent outside the fenced area.</p> <p>The data from the quadrats is presented in three different files:<br />(a) the abundance (numbers) of individuals of species within the quadrat, <br />(b) a selection of species measured within the quadrat (subplot), and <br />(c) individual plant locations within the quadrats.<br />This is version 2.0 of the Koonamore Vegetation Quadrats Survey data release.</p>
