    The Victorian Alpine Plot Network Vegetation (Insect flower visitors) Data Package contains phenology data which are sampled on the same dates, three times a year at transects situated at an altitude of 1400 m to 1880 m. These transects were established as a natural experiment - to provide infrastructure to validate the findings from the ATEX manipulated, experimental plots. The aim is to describe the phonological responses of alpine plants to environmental variables and assess the usefulness of this measure to assess vulnerability to changing abiotic (e.g. climate) and biotic (e.g. invasive species) factors. This is part of a dataset that spans from during data collected in 2011 to document long-term effects directly through climate and indirectly through biotic interactions (see methods for more information). This data package is associated with the following publication: Johanson, L. G., Hoffmann, A. A., Walker, K. L. and Nash, M. A. (2018), Bees of the Victorian Alps: Network structure and interactions of introduced species. Austral Ecology. doi:10.1111/aec.12669

    The Victorian Alpine Plot Network Vegetation Data Package contains vegetation data for four sites situated on the Bogong High Plains. Sites, which comprise multiple 1 square metre plots, are visited every second snow-free season. Vegetative growth is recorded in seven selected species, namely Carex breviculmis, Poa hiemata (Graminiods) and Celmisia pugioniformis, Erigeron bellidioides, and Plantago euryphylla (Forbs), and stems of Asterolasia trymalioides and Pimelea alpine by measuring growth amounts and converting measurements into a relative rate. This is part of a larger dataset that spans from during data collected in 2003 to document long-term effects of climate change (see methods for more information). The Victorian Alpine Plot Network research plots are revisited on a biannual basis , though measurements taken during surveys differ from visit to visit.

    This vegetation data package comprises structure and floristic data for selected points across grids described in related data packages. Vegetation attributes were recorded in an area occupying 2.5 m radius around six traps on each trapping grid and have been aggregated to grid level data. Percentage cover of all plant species, flowering index and seeding index (from 0-5, where 0 is no flowering or seeding and 5 is maximal flowering/seeding) were recorded and are presented here as plot averages which represent the mean amount of flowering or seeding per species. The network program uses a core of 12 sites. The trapping survey aims to quantitatively track long-term shifts in biodiversity and ecological processes in relation to key drivers, including unpredictable rainfall and droughts, fire, feral predators and grazing.

    This data package comprises data from a series of hemispherical photographs taken in July 2013, 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 understorey 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. 2013 was the first year a digital camera with a fish-eye lens was used to measure understorey light environments along the seedling transects.

    This data package shows longitudinal variation in seedling recruitment, the proportion of all recruits, and the corresponding number of standing seedlings for eight species of trees. These demonstrate that there is considerable variation in seedling recruitment across both species and time. These data are used to produce the graphs found in figures 5.18 on page 141. This plot consists of one 1.7 hectare plot in tropical rainforest, established in 1963. 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, and this data package describes longitudinal variation in seedling recruitment over almost four decades. 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.
