SuperSite field survey protocol development

Mirko Karan, SuperSites Coordinator

What is a TERN SuperSite?

1) An intensive field station in a typical and important biome

2) Physical instrumentation3) Scientists and technical support staff4) Transect(s) or Contrasts (10-400km)

Question driven, consistent network-wide monitoring

CURRENT STATUS: ecosystem condition, functional patterns and spatial arrangement

- stocks and fluxes of energy, carbon and water

MONITORING: response to environmental change, natural disturbance and human induced disturbance

- ecophysiological responses - changes in community composition

PREDICTIONS: Can environmental thresholds or 'tipping points' be identified and solutions suggested to avoid state change?

Challenges to address going forward:

- Standardising data formats - template driven- Improving QA QC procedures (data collection, ingestion)- Improving sensors (phenocams, acoustics)- Staffing levels and training in diverse field techniques- Assessing representativeness of plots, repetition- Valuing data set publication / citation to incentivize co-contribution

Collaborations, inter-operability

Within TERN - Calibration/validation (AusCover)- Modelling: eMAST, AusPlots, Transects, LTERN +

International - Calibration / validation (soil moisture, biomass, LAI)- Data use/reuse, modelling

Biomass - Woody plant DBH, Height, Species, Coarse Woody Debris, Clip plots,

Leaf Area Index - DCP, DHP, Point Intercept Method / clip plots PhotopointsPhenocameras (Auscover/Ozflux) - based on ACEAS workshop 2014

Soil and Water protocolsCore 1 ha plot

Initial site and soil characterisation- Soil pit at flux tower, profile, bulk density, physico-chem analysis- 9 distributed cores for physico-chem analysis

Digital Elevation Model (Auscover)Soil instrumentation (Ozflux)- Soil volumetric water content, soil temp, soil heat flux

Soil metagenomics - 16S Bact/archea; ITS Fungi; 18S Euk/algal (Baseline)

Stream monitoring – flow, pH, N, P, major ions, EC etc

Bore(s) - depth logging, pH, N, P, major ions, EC etc
