  11. Macrocystis Distribution (Giant Kelp) “old data”

  12. Nereocystis Distribution (Bull Kelp) “old data”

  13. Urchin Barren BioBand (Strongylocentrotus franciscanus) Areas of intensive urchin grazing, leaving only a white, calcareous algae Ground photo Gwaii Haanas National Park, 1992

  15. Fisheries and Oceans Canada using kelp and urchin barren biobands to represent urchin habitat capability. Model complements fishers’ log-book data and DFO dive site data to establish catch quota. Urchin Barren Distribution Dan Leus, Fisheries and Oceans Canada, Urchin Fishery Manager “Personally, I see the future of the [ShoreZone] database as being a bible for the shellfish group here. ” “old data”

  16. Research Highlights • BC province-wide dataset • 37,000 km of ShoreZone • Queen Charlotte Islands Herring Spawn • 27 years of herring spawn data • 4,660 km of ShoreZone • Sitka Sound Sand Lance Spawn Model

  17. Queen Charlotte Islands Herring – ShoreZone Analysis

  18. Queen Charlotte Islands Herring Spawn Dataset • The Queen Charlotte Islands shoreline is 4,660 km in length • There are 7,895 mapped ShoreZone units • Fisheries & Oceans Canada has mapped spawn locations for 27 years (1970 to 1997)

  19. Moresby Island Englefield Bay Herring spawn polygon data were snapped to Shore Units

  20. Summary indicates a total of 753 km have had spawn in at least one year of the 27 year dataset. • Map shows a few significant locations where spawn was very frequent (16-21 yr of the 27 year data record).

  21. Expanded view of Juan Perez Sound shows frequency of occurrence relative to Shore Units – 11 km of High Frequency Spawn Occurrence are shown.

  22. Comparison of Island-wide Occurrence to High-Spawn Occurrence Occurrence of BioBands (island-wide) Where relative proportion of spawn locations are greater than island-wide occurrence, a spawning preference is indicated: Fucus Ulva Soft Brown algae Zostera Macrocystis

  23. Research Highlights • BC province-wide dataset • 37,000 km of ShoreZone • Queen Charlotte Islands Herring Spawn • 27 years of herring spawn data • 4,660 km of ShoreZone • Sitka Sound Sand Lance Spawn Model

  24. Sitka Sound Sand Lance Beach Spawning Model

  25. ShoreZone Research ApplicationsSUMMARY • Three examples of using regional datasets for resource management: • Urchin fishery catch quotas • Herring spawn model • Sand Lance beach spawning model www.CoastAlaska.net
