  31. 31. Alaska is Different• High wetland cover• Peatlands• Functioning in “reference standard condition”
  32. 32. Alaska is Different• High wetland cover• Peatlands• Functioning in “reference standard condition”• Maintenance rather than restoration of lost function
  33. 33. Alaska is Different• High wetland cover• Peatlands• Functioning in “reference standard condition”• Maintenance rather than restoration of lost function• Assessment not on disturbance gradient
  34. 34. Alaska is Different• High wetland cover• Peatlands• Functioning in “reference standard condition”• Maintenance rather than restoration of lost function• Assessment not on disturbance gradient • Assessment for mitigation = biggest challenge
  35. 35. Alaska is Different• Maintenance rather than restoration• Assessment not on disturbance gradient •Assessment for mitigation = biggest challengeMaybe not so different:• Local control requires commitment• Unexpected outcomes most effective
