Point numbers: 249 (Warra Tall Eucalypt Wet A), 250 (Warra Tall Eucalypt Wet B), 251 (Warra Tall Eucalypt Dry B), 252 (Warra Tall Eucalypt Dry A)

Ecoregion: Temperate broadleaf and mixed forests

Participant and site owner: TERN, Tasmanian Government, Forestry Tasmania, the University of Tasmania and CSIRO

Site location: Tasmanian World Heritage Area, southern Tasmania

Latitude: -43.091

Longitude: 146.652

Site description: Warra Tall Eucalypt site was established as a Long-term Ecological Research site in 1998. Warra is dominated by Eucalyptus obliqua forest and is the focus of multi-disciplinary research into the ecological processes of these unique ecosystems. Warra has some of the tallest and largest flowering forests on Earth, and is home to a range of Southern Hemisphere rainforest plants, Tasmanian Devils, Platypus, Echidna, Cockatoos, and Wallabies. The site has experienced significant fires in recent years. The establishment of acoustic sensors in these systems will provide a record for post-fire recovery.

Site location: Bago State Forest, New South Wales

Site description: Tumbarumba, in the Bago State Forest is one of the few southern hemisphere sites that has provided records for longer than a decade of the weather, climate, net uptake of CO2 and loss of water via evapotranspiration. Bago is a managed, open wet sclerophyll eucalyptus forest, and the partnership between OzFlux and the Australian SuperSite Network is expected to improve understanding of how logging practices affect the amount of carbon and water entering, stored in and leaving the forest, and how these factors in turn influence the ecosystem as a whole. Apart from continuously measuring the exchanges of carbon dioxide and water vapour between the forest and the atmosphere, Tumbarumba has been the site of various intensive measurement campaigns to improve our understanding on how airflow, terrain and forest structure affect the way the ecosystem takes up and releases carbon and uses water. As part of this effort CSIRO has carried out independent measurements of carbon pools, stocks and turnover rates. These measurements, along with atmospheric fluxes, have been used to improve the surface–vegetation–atmospheric–transfer (SVAT) models. SVAT models describe how energy, carbon and water are exchanged between land and atmosphere, and Tumbarumba has played a major role in improving SVAT modelling in Australia over the last decade. Tumbarumba has also been a key site for measuring the important effects that vegetation has on the lower atmosphere, including the exchange of heat, and the production of particles and chemical species that are highly reactive and contribute to the formation of aerosols. A large international campaign provided measurements of the characteristics and dynamics of atmospheric ions, aerosol particles, and their precursors. Detailed observations on leaf area index taken from both hemispherical photography and forest structure measurements using Echidna have been used to evaluate plant growth and canopy cover. Echidna is a ground-based laser that scans a full hemisphere from a point on the forest floor and is used for ecological assessment and to estimate wood volume and forest growth. This is complemented by data on above-ground biomass taken through airborne LIDAR surveys carried out by AusCover. The LIDAR data, in combination with hyperspectral data, offer the means to look at forest disturbance after harvest.
