Presentation Transcript

  1. Using natural resources to improve ecosystem resilience Siôn Brackenbury, Commons Vision and Aoife Ryan, Swansea University with inputs from Professor A Street-Perrott, Phillip Harries and Robert Davidson

  2. 1. Invasive Non-Native Species (INNS) Habitat failing condition Rhododendron Control Biodiversity benefit? Other costs: Carbon flux Erosion/runoff Equipment/fuel resources Disposal – burning/chipping Impact on the soil/rhodie/disposal

  3. 2. Arisings • 170 tonnes of phytomass per ha • Disposal by: • Burning • Decay in situ • Chipping/removal

  4. 3. Pyrolysis • Energy production • Managed emissions • Creation of biochars • Sequestration within soils

  5. 4: Amendment • Analysis of soils • Determination of key characteristics • Amendment of surface characteristics

  6. 5. Mitigation • Combination of materials: • Composted bracken • Biochars and amended biochars • Testing

  7. 6. Habitat • Functional habitat? • Mixing within the soil profile • Immobilisation of metals • Sequestered carbon

  8. 7. Monitoring requirements • On-going monitoring: • Vegetation development • Soils – physical and chemical properties • Life cycle analysis • Quantified carbon sequestered Time Ecological economics

  9. Next steps: Experiments to mitigate impacts of INNS clearance on soils and biodiversity Control Cleared Burned Dense

  10. 2015 Pot trials are up and running………
