The tall, wet Eucalyptus obliqua forests predominate, and are part of the cool, temperate wet forest biome. These forests are among the most productive terrestrial ecosystems in the world and their management generates a disproportionately high social and political interest. The site also includes some areas of moorland, temperate rainforest, riparian and montane conifer forest and scrubs.
The Warra Tall Eucalypt SuperSite is partly within the Tasmanian Wilderness World Heritage Area, which is managed for conservation, and partly within State forest, which is managed for multiple purposes including wood production.

Warra Tall Eucalypt was established as a Long-term Ecological Research (LTER) site in 1998, and is one of Australia’s most scientifically productive. It is a hub for intensive, multi-disciplinary research to understand the fundamental ecological processes in E. obliqua forests and the long-term effects that management has on those processes in contrast with natural disturbance.
Current research is focussing on the bio-physical processes that support the biota and how they fluctuate across scales both spatial and temporal.
Detailed knowledge exists for many elements of the biota at Warra Tall Eucalypt their habitats, their distribution and their response to disturbance.
Importantly, research done at Warra Tall Eucalypt has directly driven improvements in forest management more generally, e.g. the introduction of variable retention silviculture in mature tall, wet eucalypt forests.
Key research objectives
- to understand fundamental ecological processes in E. obliqua wet forests
- to assess and monitor biodiversity and geodiversity
- to determine the long term effects of different forest management regimes on natural diversity and ecological processes and thus assess their sustainability
- where necessary, to develop alternative management regimes
- to provide an integrated multi-disciplinary focus which complements research programs elsewhere in Tasmania
- to link Tasmanian forest research with national and international programs having a long-term ecological focus

SuperSite installations and monitoring
TERN SuperSites core 1 ha
The SuperSites core 1 ha (100 m x 100 m) is located within the fetch of the flux tower and is the focal site of recurrent monitoring.
Hydrology and climate
Weirs occur on the Warra, Swanson and King creeks. Sampling commenced in 1998. There are 17 monthly river sampling sites on Manuka, Warra and South Weld roads. Two climate stations exist: Manuka Road (elevation 125 m) and another accessed from Warra Tall Eucalypt Road (elevation 500 m).
Continuous forest inventory plots (CFI) have been established in the area since the late 1960s to early 1970s. These are measured at establishment, at five years, 10 years and then 10 yearly.
Species lists are available for vascular and non-vascular plants, vertebrates and some invertebrate groups (see www.warra.com/warra/species_index.html ). A stratified system of baseline long-term vegetation monitoring plots has been established at Warra, to complement the CFI plots.

Warra Silvicultural Systems Trial
The Warra silvicultural systems trial in wet Eucalyptus obliqua forest started in 1997 compares clearfell, burn and sow and alternative silvicultural techniques for lowland wet eucalypt forests.
Warra Wildfire Chronosequence Plots
The Wildfire chronosequence plots were established in 2005 to investigate successional processes in the fire-adapted wet eucalypt forest landscape of southern Tasmania. Plots are located in regrowth forest derived from major wildfires in 1893, 1934 and 1966/67 as well as old-growth forest that has not experienced wildfire in over 150 years.

Southern Forests Experimental Forest Landscape (SFEFL) plots
SFEFL plots were established by Forestry Tasmania from Warra extending east to the Huon Estuary in 2009. The aim is to assess the contribution of the "Comprehensive, Adequate and Representative" reserve system in maintaining forest-dependant biota in production forest landscapes.
Baseline Altitudinal Monitoring plots (BAMPs)
The BAMPs was established in 2004 to record baseline inventory and distributional biodiversity that can be used to monitor changes in altitudinal distribution of flora and fauna over time.

Education and Outreach
Since Warra was established as a long-term ecological research site in 1995, the site has been extensively used for undergraduate studies and post graduate research projects. This site is used by local and international universities including the University of Tasmania which uses Warra for components of the undergraduate Field Botany course and in February 2016, students from Carleton College, Minnesota, USA conducted field studies there as part of an international ecology course.
The Warra Tall Eucalypt SuperSite is used for school educational activities through the National Forest Learning Centre that offers field trips to a range of forest sites including the Warra SuperSite, to Primary and Secondary School groups.
