The principal objective of this project was to develop ecosystem-specific risk thresholds for measures of indicator 2-1 (primarily soil organic matter) using a combination of field work and modelling with the ecosystem-based FORECAST model. Specific objectives are outlined below: 1) Conduct field sampling stratified by site series to evaluate initial conditions (of soil productivity measures) for productivity analysis units 2) Analyze field samples to determine organic matter content (based on % C) in the following layers: LHF, mineral soil (0-30cm), and mineral soil (30-60cm). 3) Conduct an incremental disturbance (i.e. ecosystem stress test) modelling exercise to derive thresholds for the specific measures of indicator 2-1 below which there may be a substantial loss in ecosystem productivity. 4) Conduct a modelling exercise to evaluate the potential impacts of current management practices on long-term ecosystem productivity in the context of derived thresholds. 5) Prepare a series of recommendations to provide a clear and feasible methodology for the application of Indicator 2-1 of the SFM Framework based on the results of the work.
