Hecate Strait – Queen Charlotte Sound Glass Sponge Reefs MPA ERAF Metadata

1.1.     Introduction

The Pacific Region ERAF provides a comprehensive approach for assessing all threats to marine ecosystems by evaluating cumulative risk from multiple activities to multiple ecosystem components for ecosystem-based management (EBM), improving upon international and national best practices in risk assessment that focus solely on single activities (e.g., ERAFs for assessing fisheries impacts) or single ecosystem-components (e.g., habitat-based risk assessments). This project applies the Level 2 Risk Assessment framework (O et al. 2015) to the Hecate Strait - Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area (HS-QCS MPA) to determine the relative risk to the HS-QCS MPA ecosystem from anthropogenic activities.

Species SEC Scoping

A list of species derived from published records of species observed at or within the vicinity of HS-QCS MPA. Six Supplementary Considerations were added to the six ERAF Scoping Criteria scores (O et al. 2015) to guide the selection of Species SECs in the glass sponge reef ecosystem.   The species list was last updated 2014.

This file is available from the authors upon request.

Sections 2.1, 3.1

Appendix B, C

List of Activity-Stressors

This complete list of activities for the HS/QCS Glass Sponge Reef Area of Interest was compiled by the DFO Oceans Program through consultation with stakeholders, science and policy in September 2011. It serves as a starting point for the list of Activities and Stressors ultimately used in this risk assessment.

This file is available from the authors upon request.

Section 2.2, 3.2

Appendix E, F

SEC-Stressor Interaction Matrix

List of all possible SEC-Activity/Stressor interactions.  A “1” indicates a possible negative interaction between SEC and stressor, a “0” indicates no negative interaction is expected.  The number of 1’s in this file should equal the number of data rows in the SEC Risk Scoring Table. Note:  only negative interactions are scored in the ERAF.

This file is available from the authors upon request.

Section 2.3.1, 3.3.1

Appendix G

SEC Risk Scoring Table

This table can be used directly in the associated R script to estimate risk to each SEC, cumulative risk across all stressors by SEC and potency of each stressor across all SECs.  The script can also reproduce the figures found in the research document.

Section 2.3.2, 3.3.2

Appendix J

R script

This R script (R Core Team 2017) can be used to produce the semi-quantitative risk assessment results and to reproduce the tables and figures found in the research document.  The script uses the SEC Risk Scoring Table for its input.
