Cumulative Effects Assessment in the Cariboo-Chilcotin: Review and additional values
Principles: Ecological Assessment Framework Biophysical Assessment Socio economic Assessment
. Principles: Scale Landscape, not site...but may inform site level decisions
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
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
Principles: Habitat • Habitat, not population
. Principles: Key Habitat Attributes Example moose assessment focus is winter habitat – selected components of habitat
Principles: Wildlife Habitat Concept Relationships Seral condition Habitat Capability Habitat Suitability Habitat Effectiveness Access
Values Coarse Filter • Hydrological Stability • Forest Biodiversity Wildlife Species • Moose • Marten • Deer • Grizzly Bear
Risk Assessment Tables: Components • Ecological Importance • Sensitivity and Hazards • Current Mitigation RISK = likelihood x consequence
Products: Assessment Tables Components
Products: Interpretive Maps Moose winter habitat Road density classes for Grizzly Bear
To Do • Community of Practise • Users Guide - Working Draft • Provincial coordination and expert groups • Working with the tool • Refining the tool over time
Marten Assessment Key Life Requisite: Mature Conifer Forests
Mule Deer Assessment Key Life Requisites: - Winter Range - Forest Stand Structure
Mule Deer Winter Habitat Assessment 1.Forest Structural Attributes 2. Winter Range Isolation 3. Wildfires
Grizzly Bear Assessment Key Life Requisites: Large scale habitat quality, connectivity and effectiveness
Ecological Importance Population Status Habitat Capability
Grizzly Bear Hazards Effective Habitat (%) Secure Core Habitat (%)
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
Landscape Scale Forest Biodiversity • Key Attributes: • Seral Proportions • Patch size
Ecological Importance • From 1996 Biodiversity Conservation Strategy • Ecosystem Representation in Protected Areas • Ecosystem Diversity • Threatened and Endangered Species • Sensitivity to Forest Development
Hazards Seral % compared to modelled average natural conditions using Biodiversity Guidebook Model • Spatial distribution of mature and old: • Interior Forest • Large Patches
