  2. Overview • Evaluation questions • Selection of evaluation areas • Methods • Indicators • Progress to date • Plans for next year

  3. Evaluation questions • Do access structures have the least possible impact on productive soil loss and hydrologic function of the soil? • Are harvest or road-related landslides occurring? • Are harvest or road-related slides likely to occur as a result of recent forest practices? • Are harvest or road-related gully processes occurring? • Are harvest or road-related snow avalanches occurring?

  4. Evaluation areas • Watersheds 5000 – 10,000 ha in size • Need to decide on process for selecting watersheds • Coastal areas and some Interior areas – driven by landslide issues • Many Interior areas primarily soil disturbance/permanent access issues

  5. Evaluation methods • Primarily remote sensing/GIS data collection and output • Field-level sub-sampling to confirm remote sensing results

  6. Indicators – Access Structures • % of the productive forest area devoted to permanent access • Classify roads by type and condition • Compare to assumptions contained in TSR

  7. Indicators – occurrence of landslides • Number of landslides occurring that are related to forest practices • Effect on soil productivity • Non-soil impacts (timber, fish habitat, community water supply, private property damage, injury/death of individuals)

  8. Indicators – landslide likelihood • The likelihood of harvest or road-related slides occurring within approximately the next 15 years • Need to evaluate the amount of Class IV and Class V terrain harvested/roaded, or • Use Terrain Attribute Data to predict (approximately) the number of landslides expected to occur

  9. Indicators – Gully processes • Inventory number and type of adverse gully processes • Remote sensing – scale issues

  10. Indicators – snow avalanches • Some avalanche tracks identifiable from remote sensing • Needs work

  11. Progress to date • One pilot in place – Hellroaring Creek near Cranbrook • Data being collected/summarized now

  12. Plans for next year • 2 – 3 pilots: Coast, NIR and/or SIR • Need substantial GIS resources • Need very recent aerial photography/orthophotos/satellite imagery
