  • Within the approximately 26 hectare gardens many plant and tree species are cultivated, including 450 species native to Japan growing in the open air and 11 types of Japanese forest.

  • GIS layer - map of forest types. Forest typology based on abiotic habitat parameters such as soil fertility and moisture, widely used by the forestry sector. Also available are thematic GIS layers showing historic forest and forestry data, as well as more current data on forest management (incl. timber harvesting) and such parameters as dominant species: height, age, trunk circumference (standard breast level measurement), proportion of coverage, etc.

  • Uhlířská (Jizerské Mts.) is a typical mountain catchment underlain by acidic bedrock and strongly acidified during the second half of the 20th century. Two thirds of the catchment were deforested in 1980s and subsequently reforested by Norway spruce (Picela abies) monoculture. Research here has been mostly focused on fluxes of ecologically important elements and water. The monitored characteristics include bulk and throughfall precipitation amount and chemistry, runoff amount and chemistry as well as soil chemistry, forest biomass and element pools but also plant community composition. Biogeochemical (MAGIC) and hydrological models (BROOK90) have been applied to predict future chemistry and hydrology under different scenarios of atmospheric deposition, forest growth and climate change. Hydrological processes of surface and subsurface runoff formation are studied in the catchment as a whole and in detail at the experimental hillslope Tomšovka using standard hydrologic and isotopic methods, incl. water transit time evaluation and groundwater age dating. Hydrology research focuses on water and heat flux in soil profile as well as on processes in the soil-plant-atmosphere system. Geophysical methods are used to reveal subsurface structures.

  • The Three Parks Savanna Fire-Effects Plot Network extends across three national parks (Kakadu, Litchfield and Nitmiluk) in the Top End of the Northern Territory. The fire monitoring program comprises two complementary components: satellite based mapping of fire events and on-ground assessment of change in biota at a set of permanent plots. Temporal visits are as follows: • 6 months (fire occurrence), • 4 months (fire mapping), • 5 years (vegetation), • opportunistic (fauna). Between 2012 and 2018 the Three Parks Savanna Fire-Effects Plot Network was a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN).

  • The Boyagin Wandoo Woodland SuperSite was established in September 2017 by the University of Western Australia. Located in the Boyagin Nature Reserve, approximately 12 km west of Pingelly, Western Australia the SuperSite monitoring activities complement the Avon River Catchment Critical Zone Observatory at the UWA Future Farm in Pingelly that focusses on managed landscapes (rotational dryland wheat cropping and grazing pastures for sheep). The climate is Semi-arid (Dry) Warm Mediterranean. The Boyagin SuperSite is collocated with the Land Ecosystem Atmosphere Program (LEAP) - Boyagin. Boyagin SuperSite is located in the Avon Wheatbelt (AW2-Re-juvenated Drainage subregion) and has a high density of rare and geographically restricted flora and supports populations of several marsupials subject to fox predation (Numbat, Quenda, Woylie, Tammar, Red-tailed Phascogale, Brushtail Possum) that have disappeared from most of the Australian or Western Australian mainland. The Noongar people are the traditional owners at Boyagin.

  • The Connell Rainforest Plot Network long-term forest dynamics plot of Davies Creek is located in the Dinden National Park circa 25 km southwest of Cairns, Northern Queensland. Temporal visits occur between 1 to 6 years. Between 2012 and 2018 the Connell Rainforest Plot Network was a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN).

  • Forest inventory data of LTER Zöbelboden. Beginning in 1992 permanent inventory plots covering the site (64-70) and three intensiv monitoring plots (IP1, IP2, IP3) characterising the main forest types have been recorded approximately every 5 years. The data comprises tree species identity and status, tree height, canopy height, breast diameter among other parameters describing forest structure.

  • The Nanangroe Plantation Plot Network 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 to those plantations. Its research infrastructure is comprised of an array of stratified 2-ha long-term plots. Temporal visits occur annually / biennially (rotating sampling program). Between 2012 and 2018 the Nanangroe Plantation Plot Network was a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN)).

  • The Great Western Woodlands SuperSite is a member of the Australian SuperSite Network (SuperSites, http://www.supersites.net.au/), a facility within the Australian Terrestrial Ecosystem Network (TERN, http://www.tern.org.au/). The GWW Supersite comprises a mosaic of temperate woodland, heathland and Mallee vegetation within the Great Western Woodlands (GWW) in south-western Western Australia. The core plots are located on the proposed Credo Conservation Reserve, a former pastoral lease that was established in 1906–07 where it first carried sheep and later cattle. In 2007 the lease was sold to the government and managed by the Western Australian Department of Parks and Wildlife who are collaborators on a range of projects. Native title claims of traditional ownership at this site have been registered by the Marlinyu Ghoorlie and Maduwongga Peoples. Key research objectives include: What are the impacts of climate change and management on the fundamental flows of energy, carbon, water and nutrient stocks in semi-arid woodland ecosystems. • Are old-growth semi-arid woodlands carbon sources or carbon sinks? • Are fire regimes changing in the GWW? • How do GWW biodiversity and fire fuels change with time since fire and what are the implications for fire management? • How do GWW woodlands and shrublands persist at low rainfall? What are the ecological determinants of the Menzies line (the striking boundary between the GWW and mulga) and how does it inform management for climate adaptation? • How will GWW biodiversity be affected by climate change? Will the response of fauna depend predominantly depend on vegetation responses? • How will regional versus population-scale genetic variability in key traits such as water use efficiency contribute to climate adaptation? • What are the thresholds of woodland persistence with respect to fire and rainfall? • What exotic species are invading the GWW, and which are the greatest threat under climate change?
