The Nanangroe Natural Experiment is a longitudinal (long time frame) experiment which allows the direct study of changes in fauna inhabiting woodland remnants as the surrounding grazed landscape is transformed into a radiata pine plantation. This Experiment followed on from the Tumut Fragmentation Experiment (TFE). It aims to address some of the limitations of the TFE by monitoring changes that take place over time when landscapes are transformed, such as grazed land planted with pines. The same group of animals and plants are targeted for monitoring in both the Tumut and Nanangroe projects which enables comparison between the two projects.
The Nanangroe Natural Experiment also examines the impacts of plantation expansion on biota inhabiting woodland that will be surrounded by stands of radiata pine. Monitoring began in 1998 and baseline results show that structural and landscape attributes of woodland remnants include their stability as habitat for a number of taxa including birds, mammals, reptiles, and invertebrates.
