Ecological

  • I oversaw an enthusiastic day long census with Maya, Tazi, and Ali.
  • Discovered a new Black Oystercatcher nest with 3 eggs!
  • Maya and Tazi discovered a new Canada Goose nest.
  • I begin to suspect that our new elephant seal male is actually Chuckles.
  • If he did nothing but eat for 3 months straight, that would explain his girth.
  • Saw a Steller Sea Lion branded 9628.
  • We found a blood star, and Maya showed us various chitons.
  • Maya and Tazi did a transect.
  1. Harbour Seals: 190
  2. California Sea Lions: 42
  3. Steller/Northern Sea Lions: 39
  4. Elephant Seals: 15 (13 on Great Race, 2 in the Southern waters)
  5. Seagulls: 225 (Glaucous-winged)
  6. Pigeon Guillemots: 82
  7. Canada Geese: 36 (14 on Great Race, 22 flyovers)
  8. Black Oystercatchers: 8 (plus 2 nests with a total 5 eggs)
  9. Harlequin Ducks: 3 (2 male, 1 female)
  10. Cormorants: 3
  11. Barn Swallows: 2

Maintenance

  • We cleaned the solar panels.
  • Finished cleaning the boathouse floor with T.S.P.
  • Repainted some rusty propane tanks.
  • Sanded the westward facing bench by the Students’ house.

Boats

  • Several eco-tours came by in the morning, but as wind picked up they disappeared.

Transect Peg Locations on Great Race Rocks

Expand this map of Great Race Rocks in order to see the numbered pegs in red around the shoreline. Some of these pegs were intended as intertidal locators, and some as subtidal tethering pegs. The ones with question marks still need to be located to be sure.

Some of the  pegs were established pre-1980 and some were established after 2000.

Peg 1: off west side of jetty end- subtidal
Peg 2: off point of bay west of jetty–subtidal
peg 3: further along north side– subtidal
peg 4: off base of cliff– subtidal (proved impractical because of high current)
peg 5: inter and subtidal
peg 5a:later installation- inter and subtidal
peg 5b: later installation-inter and subtidal
peg 6: for tidepool locator and intertidal and subtidal
peg 7: for subtidal minimal use
peg 8: for subtidal not used
peg 9: for subtidal not used
peg 9 : for subtidal not used
peg 10: for subtidal not used
