Chris Harvey NOAA Fisheries NWFSC, Seattle OVERVIEW: THE 2014 STATE OF THE CALIFORNIA CURRENT REPORT FROM THE CCIEA TEAM
2
Fulfills PFMC request for an annual California Current Ecosystem status update from the CCIEA team (2013 FEP, Section 1.4) Purpose of report: summarize and synthesize environmental, biological, socioeconomic indicators relevant to status of CCE Not intended to be “perfect science” but rather to be useful for the Council to consider Format, established in Nov. 2012: ~20 pages plus supplements March 2014 report covers indicators up through 2013, though some time series were most recently updated in prior years BASIC DETAILS

Page 1 has a “highlights” box that summarized some of the key indicator results REPORT CONTENTS

INDICATOR SECTIONS Climate and Ocean Drivers Basin-scale Regional Focal ecological components Copepods CPS Salmon Groundfish Sea lions Human activities Fisheries Non-fisheries Human wellbeing Fleet diversification Personal use REPORT CONTENTS
5
Some of our general conclusions: Several indicators suggest average to above average productivity in 2013 Abundance trends in salmon populations are mixed Groundfish populations mostly above biomass thresholds and below fishing mortality thresholds Non-fisheries human pressures generally low and/or declining; possibly related to economic downturn Fishery landings stable or increasing (exceptions: groundfish and salmon at or near historic lows) Some major concerns: Sea lion pup mortality Declining fishery diversification Poor spatiotemporal data for some indicators (OA, DO, forage, birds, whales) Data gaps (habitat, human wellbeing) REPORT CONTENTS
6
Most indicators shown as time series of annual means plotted around long-term mean (- - -) with ± 1 s.d. (——) Green shaded area represents most recent 5 yr of data Upper right symbol: 5-yr trend ( ↗, ↘ or ↔) Lower right symbol: 5-yr avg relative to long-term avg (–, + or ●) PRESENTING INDICATORS
7
Example here from section on non-fisheries human activities Selected indicators that we thought would best relate to PFMC interests Status and trends symbols at far right Note that lengths of time series are quite variable Details on data collection and analyses are in supplementary materials and/or long-form CCIEA reports
8
An alternate way that we summarize large numbers of related indicators is a quadrant plot 5-yr trend on x-axis, 5-yr avg relative to long-term avg on y-axis; dashed lines = 1 s.d. Symbol colors grouped geographically Quadrants color coded as a qualitative depiction of indicator condition PRESENTING INDICATORS
9
Another alternative is to present current indicator status relative to thresholds Example: assessed groundfish relative to thresholds of biomass and fishery removals overfishing threshold B MSY B limit (flatfish) B limit (elasmobranchs, rockfish, roundfish) PRESENTING INDICATORS
10
First item is the latest CalCOFI “State of the California Current” paper! CalCOFI authors include many who are also part of CCIEA team; ensures some consistency in approach, data, and scope SUPPLEMENTARY MATERIALS
11
Supplementary materials also include in-depth plots Examples: salmon abundances by population Spatial breakouts of landings (e.g., figure at right), price/lb, fleet diversification Personal use catch retention by species, sector, region Also included are details on methods, data sources, and links for additional info SUPPLEMENTARY MATERIALS
12
Are there better ways of presenting indicators? Should we include conceptual models to help “map” the indicators? SOME QUESTIONS FOR THE SSC
13
CONCEPTUAL MODELS
14
Would there be value added if we included conceptual models and “mapped” indicators onto the models? For example, we could present these as precursors to more formal risk assessment or scenario analyses CONCEPTUAL MODELS
15
Are there better ways of presenting indicators? Should we include conceptual models to help “map” the indicators? My sense is that the oral presentation that we give before the full Council is a more lasting way to “connect” with them than the 20-page report, which is a tiny part of the briefing book. Is that a correct assumption? How do we distinguish IEA status/trends report from the other “state of the California Current” reports out there? Are there other IEA products that would add value to this report? We have more integrative products, but they depart somewhat from the “status and trends” notion SOME QUESTIONS FOR THE SSC
