Connell University of California This data package comprises data from a series of hemispherical photographs taken in July 2013 and May 2015 at the Connell Rainforest Plot near O’Reilly’s Guest House, 85 km south of Brisbane, Queensland. The 2.0 ha site consists of separate 1.0 ha plots separated by 600 m, but they have always been treated as a single entity. The site consists of mapped and tagged trees in all size classes from tiny seedlings to large canopy trees. Rates of recruitment, growth and mortality have been measured at intervals of 1-6 years with records extending back to 1963. The primary determinant of growth rate in the understory is light. 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 Green at La Trobe University. A digital camera with a fish-eye lens was used for the first time in 2013 to measure understory light environments along the seedling transects. A synopsis of related data packages which have been collected as part of the Connell Rainforest Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/connell-rainforest.

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

The understory light environment was characterized in July 2013 and May 2015 using a digital camera fitted with a fish-eye lens. The Sony NEX7-2380605 DSLR Compact-269 camera, lens and analytical software were purchased as a package from Regent Instruments Canada Inc (www.regentinstruments.com). The analytical software (WinScanopy 2013a) for Canopy Analysis) is designed to be fully integrated with the camera, and the camera settings were set to the specifications in the WinScanopy user manual. The camera was mounted in a self-levelling gimbal 1.6 m above the ground. Photos were taken at intervals of 12.5 feet along all transects on which seedlings and small saplings are mapped; Lines 1, 3, 4, 6 and 8. The gimbal comes with a an automatic north-finder; in each image, north is indicated by the a small red dot on the edge of each image. Because the plot is small, single values of latitude and longitude were used for all images. The WinScanopy image analysis output is more than 100 data columns wide – only the most useful are included with this data package. See Sampling Description 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).
