Cumulative Effects Assessment in the Cariboo-Chilcotin : Review and additional values

1. Cumulative Effects Assessment in the Cariboo-Chilcotin: Review and additional values

2. Principles: Ecological Assessment Framework Biophysical Assessment Socio economic Assessment

3. . Principles: Scale Landscape, not site...but may inform site level decisions

4. Principles: Scale • Scale – multi landscape • Wildlife values: units 15,000 to 30,000 ha (approximately 350 units in region) • Hydrology: watersheds, basins, sub-basins • Mule deer: winter range

5. Assessment focus on current land condition Future developments can be added but forest estate does not grow Principles: Current and Future Conditions Now Future Proposal

6. Principles: Habitat • Habitat, not population

7. . Principles: Key Habitat Attributes Example moose assessment focus is winter habitat – selected components of habitat

8. Principles: Wildlife Habitat Concept Relationships Seral condition Habitat Capability Habitat Suitability Habitat Effectiveness Access

9. Values Coarse Filter • Hydrological Stability • Forest Biodiversity Wildlife Species • Moose • Marten • Deer • Grizzly Bear

10. Risk Assessment Tables: Components • Ecological Importance • Sensitivity and Hazards • Current Mitigation RISK = likelihood x consequence

11. Products: Assessment Tables Components

12. Products: Interpretive Maps Moose winter habitat Road density classes for Grizzly Bear

33. Ecological Importance Population Status Habitat Capability

34. Population Status

35. Grizzly Bear Hazards Effective Habitat (%) Secure Core Habitat (%)

36. % Effective Habitat

38. Secure Core Areas • = Road-less areas with greater than 10 square km of capable habitat • Size based on area used in a 24 hour period by female bear with cubs • Proportion of Secure Core is an index to mortality risk for grizzly bears

39. Comparison of road-less areas extirpated status

40. Grizzly Bear Indicators

41. Landscape Scale Forest Biodiversity • Key Attributes: • Seral Proportions • Patch size

42. Ecological Importance • From 1996 Biodiversity Conservation Strategy • Ecosystem Representation in Protected Areas • Ecosystem Diversity • Threatened and Endangered Species • Sensitivity to Forest Development

43. Hazards Seral % compared to modelled average natural conditions using Biodiversity Guidebook Model • Spatial distribution of mature and old: • Interior Forest • Large Patches
