Pluvialis squatarola: Black-Bellied Plover- The Race Rocks Taxonomy

 

Pluvialis squatarola at Race Rocks, September 28, 2009.
This is our first photo of this plover, taken by Ryan Murphy

Ryan photographed these plovers in their non-breeding plumage  (missing the black belly!) on the lawn at Race Rocks. The top one o was here on March 11, 2010.

These are long-distance migratory birds. They were here as a stopover on the migration, fall and spring. They breed on the arctic tundra and winter on sandy beaches and wetlands in coastal areas from central North America through southern South America. They use the run, stop and stab at the food behaviour common to many plovers.

Melibe leonina: Hooded nudibranch–The Race Rocks Taxonomy

melibe3This is a hooded nudibranch (Melibe leonina)… a predatory sea slug that ‘swims’ more often than it crawls. The front end (on the right) has rounded sensory organs called rhinophores that look a bit like elephant ears. In the other picture you can see the head has a big mouth and that can expand to capture all sorts of little critters. The branching structures are ramifications of the digestive system (hepatic diverticula).

Race Rocks Update May 2009

Eight Years Later: It is with irony that I write this update, 8 years to the day since Angus Matthews wrote an update in 2002

In 2001 we were still optimistic that a full fledged MPA for Race Rocks would be forthcoming. In the interim, most of the members of the Race Rocks Advisory Board have moved on. As for the representatives of Lester Pearson College, Angus Matthews is now Executive Director of the New Marine Centre in Sidney, and Garry Fletcher has retired from teaching at Pearson College, but remains as Educational director of the racerocks.com website and assists with advice in the administration of the reserve. Chris Blondeau, the Director of Operations of Lester Pearson College is now in charge of administering Race Rocks for the College.

In the interim, Lester Pearson College has continued to raise funds to provide an Eco-guardian at Race Rocks since the de staffing of the Lightstation in 1997. Mike and Carol Slater retired in 2008. and Ryan Murphy, a former student of Lester Pearson College and now a graduate student from Memorial University is now hired as our resident Eco- Guardian. Over $1,000,000 has been raised by Lester Pearson College dedicated to the protection of the reserve since 1997. BC Parks has been helpful in providing for infrastructure upkeep on the island . DFO has not contributed anything to the operation of the reserve.

The rejection by the First Nations of the Gazetted version of the Advisory Board proposal of 2001 led to a cessation of the advisory process . A significant change in the text of the original proposal of the Advisory Group when it was submitted to DFO made the proposal unacceptable to First Nations as well as to many others of the Advisory board.

Sean LeRoy et al, have analyzed the process and have documented it in the Publication : Public Process and the Creation of the Race Rocks Marine Protected Area

From page 8:

” On October 28, 2000, the draft regulations for the XwaYeN (Race Rocks) Marine Protected Area appeared in the Canada Gazette, Part I (O’Sullivan 2000). The proposed regulatory text established the no-take zone within the boundaries of the Ecological Reserve. The accompanying Regulatory Impact Analysis Statement (RIAS) incorporated most of the other consensus recommendations of the RRAB, but also stated: “…although the creation of the MPA does not restrict harvesting by First Nations for food, social or ceremonial purposes, they volunteered to forego this activity in support of the designation of the MPA”

This provision was a surprise to the CSSC, other members of the RRAB, and many at DFO. In November 2000, the Chiefs of several Douglas Treaty First Nations wrote a letter of objection to the Minister of Fisheries and Oceans, citing the Delgamuukw vs. British Columbia (1997) decision, infringement of treaty rights, and lack of consultation (RRAB 2001). It is not clear whether this objection was a direct result of the Gazette publication, or whether it derived from earlier events such as Miramichi Bay or the ‘designation’ ceremony. Regardless, the regulatory process was halted immediately. Caught in the crossfire, the CSSC lost any currency it had as an intermediary between the Douglas Treaty First Nations and DFO, and has not been involved in the deliberations ever since.
In December 2000, DFO met individually with each Chief of the Douglas Treaty First Nations, acknowledging that proper consultation had not taken place (RRAB 2001). By June 2001, the Chiefs had written a letter of support for the MPA, on the condition that there was true co-operation and acknowledgement of Douglas Treaty rights. Negotiations to allow the final designation of the MPA are currently ongoing (April 2003). “

During the interim since 2001, DFO has pursued negotiations with the local First Nations Treaty Group. In April of 2009, DFO representatives have expressed interest in resolving the issues this year.

So now from my viewpoint in 2009, the perspectives on the MPA process have changed somewhat. We are currently committed to maintaining the ecological sustainability of the provincially designated Ecological Reserve. The Ecological Reserve has now been in operation for 29 years. The community has accepted the importance of the area and has recognized the value of conservation. It would be of great assistance to Lester Pearson College if the area was to become financially sustainable with support from governments. I am not so sure however if the designation of MPA status remains of any value.

On the DFO webpage http://www.pac.dfo-mpo.gc.ca/oceans/mpa/fntreaty_e.htm the following is a statement on
Respecting First Nations and Treaty Process :

“Canada and B.C. consider First Nations support and participation in the MPA Strategy as important and necessary.  Both governments will ensure and respect the continued use of MPAs by First Nations for food, social and ceremonial purposes and other traditional practices subject to conservation requirements.  Therefore, MPAs will not automatically preclude access or activities critical to the livelihood or culture of First Nations.  The establishment of any MPA will not preclude options for settlement of treaties, and will address opportunities for First Nations to benefit from MPAs.”

Given the above statement it is hard to imagine why 9 years has passed without this being resolved and why no support in the interim has been forthcoming from DFO for the Ecological Reserve. It would appear that it is successful as it is now so one might wonder why adding another layer of bureaucracy is necessary.

The above statement represents the personal opinion of Garry Fletcher.

Tringa melanoleuca: Greater Yellowlegs , The Race Rocks Taxonomy


Tringa melanoleuca at Race Rocks Photo R. Murphy
Although this species was first photographed at Race Rocks in 2009, it is a relatively common shorebird that occurs in large numbers when migrating through this area from March to May. Their breeding habitat is bogs and marshes in the boreal forest region of Canada and Alaska, nesting on the ground, in well-hidden locations near water. ( Wikipedia)

David Allinson of the Rocky Point Bird Observatory comments :”This is a moulting into breeding Greater Yellowlegs . Note the legs look pretty yellow to me (but at this time of year and in certain light they can look orangeish). Lots of both Tringa’s are moving through our area right now…(For Greater Yellowlegs, listen for their loud ‘tiew, tiew, tiew’ calls, esp. when in flight…but Lesser’s should be fairly uncommon out there… (they prefer mudflats over rocks; whereas Greater’s can be seen on either).

Ninene the Elephant Seal pup Returns to Vancouver Island April 15, 2009

Ninene on Taylor Beach

Ninene starts back up the shore on Taylor Beach to the dry sand.

Ninene on Taylor Beach

She is now 2 and a half months old.

What a pleasant surprize to see little Ninene this afternoon down in front of my home on Taylor Beach on Southern Vancouver Island. She has come through a load of problems and remarkably has made it this far. She was born on Race Rocks on January 30, 2009. Was weaned four weeks later when her mother left, was then badly beaten up by a young aggressive male, who was then driven off by Slash an older male, possibly her father, then she stayed on Race Rocks alone until March 30 without feeding, She then left Race Rocks on March 30, and arrived in Port Angeles on April 7, was moved from downtown to Ediz Hook Coastguard station. and then disappeared the next day. She showed up at 2 and a half months age on Taylor Beach in Metchosin , Southern Vancouver Island. In the past few weeks has traveled well over 50 kilometres.

She has been on the sandy part of Taylor beach , has just gone to the water to get cooled off …

Video of Ninene

Video of her on the beach April 15, 2009

When she was banded and observed in Washington, several researchers there believed that Ninene did not gain as much weight with her mother as she should have, so she is considered to be underweight for her age. So at this point she still is in a vulnerable situation and we hope she is able to forage well and put on more weight very soon. Ninene stayed only for the day and night. Hse was gone the next day, and we have never seen her since (as of 2014)

Distribution; rocky areas though at exposed and protected coastal waters. 

strongylo

This Giant Red Urchin contrasts with the Metridium beds at Race Rocks

Habitat: Rocky substrates, especially ledges and crevices located near bull kelp beds and other brown algae in area of moderate to swift currents. Larvae drift and feed in plankton, juveniles settle near kelp bed, often associate with aggregation of adults, remain under adult spines until they reach 40mm.

Behavior: The red sea urchin is found in deeper water than the purple sea urchin. It is seen from the low intertidal area to as deep as 90 meters. The urchins move their feet by a hydraulic system which creates suction in the end of the food by pulling water out the madroporite. These tube feet may also be used to sense of smell the chemicals in their surroundings like others urchins, the red sea urchin can regrow its spines if they are broken. On full size urchins, these spines sometimes shelter small juveniles.

seaurchgraze

Grazing marks on the stypes of Nereocystis sp.

Reproduction: The spawning of red sea urchin peaks between, June and September in southern BC. The fertilized eggs develop into planktonic larvae before settling on the bottom where they change into tiny juvenile sea urchins. This replenishment of the population, appears to occur annually in local waters. New recruits must hide from potential predators and many seek shelter under the spines of adult . Adulthood is at approx. 3cm diameter and legal size of 10cm is reached in five to ten years. Life span sometimes exceeds 30 years.

People eat the gonads (sexual organs, called “UNI”) of this urchin. It is especially a delicacy in Japan and others parts of Asia. Sunflower stars, some fish, birds, and sea otters also prey on them.

This pdf is on the DFO Integrated Fisheries management Plan for the Red urchin:

DFO-red_urchin_2011-12 “The purpose of this Integrated Fisheries Management Plan (IFMP) is to identify the main objectives and requirements for the Red Sea Urchin fishery in the Pacific Region, as well as the management measures that will be used to achieve these objectives. This document also serves to communicate the basic information on the fishery and its management to Fisheries and Oceans Canada (DFO) staff, legislated co-management boards and other stakeholders. This IFMP provides a common understanding of the basic “rules” for the sustainable management of the fisheries resource.”
