Connell Rainforest Plot Network: Subtropical Rainforest Tree Demographic Data, O’Reilly’s Plot, Lamington National Park, Queensland, Australia, 1963–2013

Abstract: This rainforest tree demographic data package comprises recruitment, growth and mortality census data for rainforest trees at the O'Reilly's Plot, Lamington National Park (84km south of Brisbane), Queensland for 1963–2013. The O’Reilly’s Plot consists of two 1.0 hectare plots spaced 600 m apart in sub-tropical rainforest, which 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. 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.

Methods

General Methods
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, the reader should refer to a comprehensive description of the methods and the plot configuration provided in the Conceptual Design (p 84) and accompanying documentation.
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.
Measuring tapes especially imported from the United States – ft 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

Natural disturbance monitoring
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.
3
Floristic identification, vouchers and lists
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.

Surveys for canopy cover and understorey light environments
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 incorporated into regular plot monitoring.

nominal enumeration codes
1large trees whose size was measured as diameter, not girth, due to the presence of large buttresses. In 1992 most of these were remeasured as girth above the buttress, from 6 to 12ft above the ground. The 1992 data are OK for basal area, but since measurements before 1992 are inaccurate, they should be omitted when calculating basal area or analysing growth.
2trees found in field in 1992 and 1993 which could not be located in the Master File, so original field notes need to be consulted before these can be used for analysis
3those seedling recruits from incomplete surveys which were dead the next complete recruitment survey. Omit from analysis of recruitment. The years are as follows: O’Reilly’s: 1963 dead 65, O’Reilly’s & Davies Creek: 1976 dead 78, O’Reilly’s & Davies Creek: 1992 dead 93
6trees > 25.0" Girth 1, that occur at O’Reilly’s on Line 5, x=300 to 1800. They were mapped in 1963 and have been census and remeasured fairly regularly. They should be included only in those analyses in which only trees >25.0 girth are used, where they will be useful to increase sample sizes of larger trees.
