1 NOAA FISHERIES SERVICE Habitat Assessment Prioritization

2 What is a Habitat Assessment? A habitat assessment is both the process and products associated with consolidating, analyzing, and reporting the best available information on habitat characteristics relative to the population dynamics of fishery species and other living marine resources. The ultimate goal of a habitat assessment is to determine the function of habitats in relation to fishery production and ecosystems, thereby supporting management decisions that are a mandated responsibility of NOAA. Habitat Assessment Improvement Plan (NMFS, 2010)

3 Hudson Canyon Benthic Habitats What is habitat? Two Definitions: Physical Habitats as defined in this map (Landscape Ecology definition) Stock Habitats as used by NMFS (Autecological definition) After Pierdomenico et al Tilefish Habitat

4 NOAA FISHERIES SERVICE Scheme originators: Office of Science and Technology, F/ST Habitat Assessment Prioritization Working Group (HAPWG): Report 2011 As Modified by: the Southwest Regional Habitat Assessment Prioritization Working Group: Report 2012

5 THE ISSUE: THE FUTURE OF HABITAT AND STOCK ASSESSMENT SCIENCE The Habitat Assessment Improvement Program (HAIP) recommends: NMFS should develop criteria to prioritize stocks and geographic locations that would benefit from habitat assessments. NMFS should identify and prioritize data inadequacies for stocks and their respective habitats, as relevant to information gaps identified in the HAIP.

6 THE HABITAT ASSESSMENT PRIORITIZATION PROCESS 1. Scoring is split into two separate lists to support the main objectives outlined in the HAIP: Priorities for habitat science supporting stock assessments (Stock Assessment Theme), and priorities for EFH science (EFH Science Theme).

7 THE HABITAT ASSESSMENT PRIORITIZATION PROCESS 2. Scope is focused on Federally-managed fish stocks geographic context is provided by stock area distributions and species habitat utilization patterns.

8 THE HABITAT ASSESSMENT PRIORITIZATION PROCESS 3. Process uses two types of criteria to consider each stock: Filter Criteria, which stocks must meet in order to be further considered in process; and Scorable Criteria, which assigns numeric scores independently to each stock based on its qualifications against a set rubric.

9 THE HABITAT ASSESSMENT PRIORITIZATION PROCESS 4. Weighting factors may be applied to some or all criteria categories. However, weighting must be assigned prior to scoring and the HAPWG recommends weighting be used judiciously.

10 THE HABITAT ASSESSMENT PRIORITIZATION PROCESS 5. Once final scores for each theme are calculated, eligible stocks are sorted into high/medium/low priority categories as assigned by the regional groups.

11 THE HABITAT ASSESSMENT PRIORITIZATION PROCESS 6. Each regional group should present its results in a report that provides a summarized list of stocks for each theme area, an appendix containing a table of raw scores, and additional text as needed to explain or justify scores, identify knowledge gaps and suggest research, and provide other useful information.

12 Filter Criteria (Rating Value is 0 or 1 no or yes): 1. Stock Assessment & EFH Science Themes: FMP Stock Listed in the FSSI or is a Regional FMC Priority? 2. Stock Assessment Theme: Is Habitat Assessment Likely to Benefit Stock Assessment? 3. EFH Science Theme: Is Habitat Assessment Likely to Inform EFH Science?

13 Scorable Criteria (Rating Value range 0-5 and are additive): Theme-Specific Scorable Criterion: Benefits of a Habitat Assessment to Stock Assessment Theme-Specific Scorable Criterion: Habitat Assessment Likely to Advance EFH Information Common Scorable Criterion: Fishery Status Common Scorable Criterion: Regional FMC Priority

14 Scorable Criteria (Rating Value range 0-5 and are additive): Common Scorable Criterion: Habitat Disturbance, Vulnerability, and Rarity Common Scorable Criterion: Habitat Dependence Common Scorable Criterion: Ecological Importance Common Scorable Criterion: Economic, Social, and Management Value

19 Scorable Criteria (Rating Value range 0-5) : Theme-Specific Scorable Criterion: Benefits of a Habitat Assessment to Stock Assessment Assessment is likely to result in: an SAIP Level 5 stock assessment, an HAIP Tier 3 habitat assessment, or improve performance within an existing SAIP Level 5 or HAIP Tier 3 assessment 5 pts. improved survey efficiency or efficacy, reduce sampling variability, or improve the analysis of fishery catch per unit of effort (CPUE) data used in a stock assessment 3 pts. provide new opportunities to develop stock assessment modeling or survey techniques that incorporate the relationships between habitat and population processes or data variability 1 pt.

20 Scorable Criteria (Rating Value range 0-5): Theme-Specific Scorable Criterion: Habitat Assessment Likely to Advance EFH Information Habitat assessment would likely provide an initial definition of EFH. - 5 pts. Habitat assessment would likely provide an increase in information sufficient to increase between EFH levels of knowledge. 4 pts. Habitat assessment would likely provide an increase in information within the existing EFH level of knowledge. 1 pt.
