Brief DescriptionThis rainforest tree data package comprises stand structure data for rainforest trees at the O'Reilly's Connell Rainforest Plot, Lamington National Park (84 km south of Brisbane), Queensland for 2015.
Full DescriptionAbstract: his rainforest tree data package comprises stand structure data for rainforest trees at the O'Reilly's Connell Rainforest Plot, Lamington National Park (84 km south of Brisbane), Queensland for 2015. The O'Reilly's Plot consists of two 1.0 hectare plots spaced 600 m apart in sub-tropical rainforest, established in 1963. They have always been treated as a single unit for the purpose of analysis. Rainforest tree attributes recorded comprise the size (height or girth) of tagged and mapped, free-standing stems of shrub and tree species. Sampling has been undertaken at intervals of 1-6 years since 1963. It essentially provides a snapshot of stand structure on the site. This data package forms part of the collection of vegetation data undertaken at plots situated in both Lamington National Park and Davies Creek initiated by Professor Joseph H. Connell (University of California, Santa Barbara) in 1963.

A synopsis of related data packages which have been collected as part of the Connell Rainforest Plot Network's full program is provided at https://doi.org/10.25911/5c13444388e1b.

Sampling method: The O'Reilly's Plot consists of two 1.0 hectare plots spaced 600 m apart, which have always been treated as a single unit for the purpose of analysis. This data package forms part of the collection of vegetation data undertaken at plots in Lamington National Park which were initiated by Professor Joseph H. Connell (University of California, Santa Barbara) in 1963. The same sampling methods are employed in a related data package focussing on tropical rainforest plots at Davies Creek, Dinden National Park (1.7 ha, 25 km south-west of Cairns). Sampling has been undertaken at intervals of 1-6 years.

Project abstract: This group conducts research in the rainforest investigating tree demographics.

Project funding: The National Science Foundation was the sole funder of this research between 1963 and 2003.

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.

General Methods
Description
Prof Joseph H. Connell (University of California, Santa Barbara) established a long-term forest dynamics plot in 1963, in subtropical rainforest near O’Reilly’s Guest House in Lamington National Park, 84 km south of Brisbane. The plot layout consists of two 1 ha plots spaced approximately 600 m apart; these have always been treated as a single unit for analyses. This plot has never been logged, but some selective logging has occurred just outside the plot boundary.
Although a summary of methods employed in the study has been provided below, a full account of the field methods, with figures of the mapped study plots, is given in:
- Connell, J.H., J.G Tracey & L.J Webb, 1984. Ecological Monographs 54: 141-164.
- Connell, J.H. & Green P.T. 2000. Ecology 81: 568-584
In summary, samples of trees in three broad size classes have been monitored on the plots over several decades. 'Large trees’ (≥ 10.0 cm dbh) were first tagged, mapped and measured in 1963 across both plots. At the same time, ‘medium trees’ (2.5 cm dbh but < 10.0 cm dbh) were mapped and tagged along several belt transects 6.1 m wide running through the plot, centred on survey lines 20.1 m apart. The medium-tree belt transects comprise 30% of each plot. In 1965, ‘small trees’ (tiny seedlings to saplings < 2.5 cm dbh), were mapped and tagged along narrower transects either 1.8 or 3.6 m wide, centred on the same survey lines used to sample medium trees. Large trees rooted outside the plot boundaries, but whose canopies extended over the plots have also been monitored.
Large and medium trees are tagged with numbered aluminium tree tags inscribed with a unique number, nailed into the trunk with galvanized nails. Small trees are also tagged with numbered aluminium tags, attached to the plant using loops of insulated copper wire. The plots are laid out and trees are mapped using imperial and engineering units (feet and tenths of feet). Large and medium trees are measured for girth at breast height using inches and tenths of inches, and small trees are measured for height in feet and tenths of feet. These are converted to SI Units for analyses and publication. The belt transects comprise 30% of each plot (See Fig. 1). The seedlings of vines are occasionally tagged by inexperienced workers, but these are excluded from analyses.
Further details relating to the methods employed by the Connell Rainforest Plot Network during this study can be found on the LTERN Plot Network site.
Instrument
Measuring tapes especially imported from the United States – feet and tenths of feet, and inches and tenths of inches. Star pickets mark the ends of transects, and short steel posts mark transects at 25 feet intervals. Plants are tagged with numbered aluminium tags, attached to the plant using loops of insulated copper wire on smaller stems, or nailed onto larger stems. There are no environmental monitoring devices on the plot

Title
Natural disturbance monitoring
Description
Gaps created by the death of large canopy trees have been systematically surveyed many times over the decades until 2002, with the boundaries of the gaps being noted on hand drawn maps. These maps have never been digitized, and the originals are held at the University of California. Copies of some later maps are held by Peter Green at La Trobe University.

Title
Floristic identification, vouchers and lists
Description
Voucher specimens have been collected on an ad hoc basis over the years for many individuals on both plots. These specimens are curated at La Trobe University. Species lists are updated as taxonomic changes are published. Taxonomic revisions pose some problems for analyses; it is impossible to apply the revised taxonomy to un-vouchered dead stems.

Title
Surveys for canopy cover and understorey light environments
Description
Stand structure, canopy cover and variation in understorey light environments have not been measured systematically on the plots. Under LTERN, new surveys for canopy cover and understorey light environments using hemispherical photography are being be incorporated into regular plot monitoring.
