This data package consists of standardised vegetation condition measurements from the Nanangroe Plantation, NSW. Surveys are done every five years in three vegetation structure plots (20 m × 20 m) nested within the 2-ha sites. This survey measures ground cover, percentage of vegetation cover, species richness and structural measurements for each plot. The principle objective of the Nanangroe study is to directly quantify changes in woodland vertebrate assemblages and their relationships with habitat variables when the surrounding landscape matrix is converted from a semi-cleared grazing landscape to a landscape dominated by an exotic softwood plantation. The study area is located in the Southwest Slopes of NSW west of Lake Burrinjuck and includes four exotic Pine Plantations (Nanangroe, Cotway, East Bungongo and Bungongo), as well as private properties adjacent those plantations. Repeated sampling of the vegetation structure and cover and selected vertebrate groups on all sites from 1998 has created a long term dataset. A synopsis of related data packages which have been collected as part of the Nanangroe Plantation Forest Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/nanangroe-plantation.

These data show the change in basal area and stem number following infection by Cinnamon Water Mould (Phytophthora cinnamomi) at the Garrawalt permanent plot NW of Townsville between 1975–2009. It demonstrates the recovery in dieback areas in Australia's tropical rainforests. The data tables attached are used to generate the graph in Figure 5.11 on p133 of the book Lindenmayer et al. 2014 Biodiversity and Environmental Change: Monitoring Challenges and Direction. The CSIRO permanent rainforest plots are located within 60 km of the north Queensland coast between Mackay (21.5ºS, 149ºE) and the Iron Range on Cape York Peninsula (12.5ºS, 143ºE). The plots have a rainfall range of 1200 to 3500 mm, represent eleven vegetation types, six parent materials, and range from 15 m to 1200 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.
