SCEAM Project

• SCEAM Project commenced in 2004
• Jointly funded by NRM North, Cradle Coast NRM
  South, NHT and In-Kind DPIW
• Aims
• Establish 300 Soil Reference Sites Across
  Tasmania on a Variety of Different Soil Land Use
  Combinations (Private Public Land)
• Develop Cost-Effective and Simple Sampling/
  Monitoring Procedure
• Establish Baseline Soil Condition Values
• Establish Soil Condition Target Values
  (Environmental Economic)
• Monitor Sites to Establish Trends in Soil
  Condition under different Land Uses and
  Management Practices
• Identify Beneficial Land Management Practices

SCEAM

• Soil Land Use Combinations Include
• Ferrosols-Intensive Cropping (min 8/10yrs)
• Sodosols-Cropping (min 4/10yrs)
• Plantation Forestry-Dermosols/ Ferrosols
• Native Forestry-Dermosols/ Ferrosols/ Duplex
• Irrigated Pasture-Ferrosols
• Perennial Horticulture-Dermosols
• Vertosols Cropping
• Podosols- Dryland Pasture
• Plus a variety of soils on Grazing (north-facing
  slopes), certified organic grazing/ cropping,
  rural tree decline sites etc

SCEAM

• Method
• ID Site, Collect Land Use Management History
• Sub-metre GPS fix
• Sample 50m transect, 2m intervals, Bulk surface
  (0-75mm) and Bulk sub-surface (within 75-300mm)
• Bulk Density and Aggregate Stability Samples at 3
  points along transect (both depths)
• Characterisation Pit , Description ASC
  Classification
• Full Chem Analysis (CSBP WA)
• Aggregate Stability (Wet Sieving) Bulk Density
• Archive Samples (DPIW Canberra CSIRO Land
  Water)
• Sites put on ASRIS

SCEAM

• Initial Results
• 294 Sites Established
• Need to Re-Assess Target Values
• Re-Analyse several interesting results
• Investigate Outliers

SCEAM Future

• SCEAM Final Reporting
• Cradle Coast Contaminants and Biological
  Sampling
• Rigorous SCEAM Data Analysis
• Continued SCEAM Monitoring
• Establish opportunistic new sites
