Race Rocks Ecological Reserve Warden’s Report June 14 2024

Garry Fletcher, ER Warden for Race Rocks visited the reserve on June 14, 2024

Greg Dickinson from Pearson College provided transport in Second Nature for the following group: 

  • Lisette and Mads – Mads is a  former student and both are volunteering at Pearson College
  • Garry Fletcher – Park Warden
  • James Tuohy – future Ecoguardian
  • Ann Nightingale and Andrew Jacobs – Rocky Point Bird Observatory

Upon docking I was struck by the number of Pigeon Guillemots on the rocks . Although I haven’t checked back in our records, there certainly seems to have been an increase in numbers 

We were greeted by the new ecoguardian  Christine  Chourmouzis .  In addition to having a general survey of the reserve, I was able to direct Christine and James through the process of entering them as editors on racerocks.ca and creating a log and posting it on the Race Rocks website. 

Supplies for the Ecoguardian are off-loaded

 

 

 

 

 

 

Pigeon Guillemots also nest on the island

 

When I was teaching at Pearson College, we often monitored a set of tidepools out on the island’s West side. I checked out those pools again and took photos which show the state of algae growth. Some observations in the tidepool files provide a baseline for comparative studies in the future.  These files are on the tidepools

Today’s observations are in the set of photos below

I checked pool #4 which has a white quartz intrusion through it to see if the white periwinkle snails were still there. 

 

A review of some of the installations on the Island

 

Due to recent notices on social media about the problems that pet owners are having when their dogs get exposed to foxtail , I was concerned about whether there was a similar problem with marine mammals. This guy certainly seems to be enjoying the location however. 

I tried to find the small patch of the rare plant  seaside  plant Romanzoffia on the rocks on the East side of the house.  Unfortunately the area was covered with knotweed now. We will have to check again in the winter. 

The Turkish marsh gladiolus is now in bloom. This is a good example of a garden escape, planted by lighthouse keepers probably as much as 80 years ago, they still come up every summer .

 

 

Polygonum aviculare : prostrate knotweed- The Race Rocks taxonomy

This summer there is a proliferation of knotweed in areas on Race Rocks in which it has not occurred before :  also see: https://racerocks.ca/polygonum-aviculare-prostrate-knotweed-the-race-rocks-taxonomy/

Race Rocks Ecological Reserve #97 Warden’s Report ,April 19 2022

We departed Pedder Bay on Second Nature with Greg who was taking Joan Rosenburgh out for an Ecoguardian exchange.  Before leaving we noted a new perch location on the new docks at Pearson College .

 

On arrival, a nice greeting from the group of Northern and Californian sealions near the docks

I took photos of all the adult elephant elephant seals still at the reserve :

 

 

There have been many improvements that the Ecoguardians and the college staff have done since the last time i was here.One important improvement has been the installation of a new toilet system which seems to be a big improvement over past models.

I was interested in relocating the spot where a new geo-positioning system was installed last year, since I had been unable to locate it one time when i was out there. So these pictures are for future reference for relocation. When scientists come out to recheck , the results from satellite triangulation at this spot can indicate the amount of tectonic plate movement .

 

 

 

Stunning Weather, Spring at Full Force!

Weather:

  • Visibility 15+ NM
  • Sky clear
  • Wind 5-10 knots SW
  • Sea State: calm

Marine Traffic/Visitors:

  • 2 jet skis yesterday evening, 1 kayak this morning, 1 eco-tourism vessel yesterday
  • Greg today with supplies (thanks Greg!)
  • 1 boat inside the reserve fishing this morning- Greg stopped to remind them that they were within the boundary on his way
  • Many pleasure crafts just outside of the reserve boundary

Ecological: 

  • Consistent eagle presence as the seagulls continue to return, and food is plentiful in the water
  • The geese seem to be getting pushed out of their territory by the seagulls. The seagulls have continued to steal goose eggs when they get an opportunity, thus there are only 2 remaining nests with eggs. The geese have started to spend more time on the water, and often leave during the day.
  • The pineapple weed has been growing at an impressive rate! Most of the grassier areas on the island are covered by the fluffy foliage.

 

Coralline Algae Discoveries, Impossible Invasive Plants

Weather:

  • Visibility 15+ NM
  • Sky clear
  • Wind 5-10 knots SE
  • Sea state: calm

Visitors/Marine Traffic: 

  • One medium sized catamaran passed through race passage this morning drifting on the current
  • This afternoon we were joined by Guy and Christine, who brought us some generator hardware and spent a bit of time enjoying the beautiful weather.
  • Quite a bit of commercial traffic outside the reserve today including barges of logs and shipping containers.

Ecological: 

  • There are quite a few beginnings of seagull nests now. They have become more aggressive, and now fight each other over space. We have seen some pairs mating.
  • We have been finding coral-like white fragments in the intertidal since last year, but until now have not been able to identify what they could be. Today we found some that were not white, but red! This insight has led us to believe that this is coralline algae. Amazingly, this article states that these unassuming structures can continue to grow forever (!) if left undisturbed and have growth rings that be counted, just like trees!
  • As Gary Fletcher mentions in this post, prostrate knot weed is one of the invasive species here on Race Rocks. We noticed that it is particularly efficient at growing in places where no other plants are able, therefore it’s beginning to spread in rocky areas. It has notably spread to the rocky areas on the SW side of the island where no other flora nor fauna has managed to establish itself.

 

Whales! (and census)

Spotted: Turkish Marsh Gladiolus!

Weather:

  • Visibility: 5 miles
  • Wind: 12 knots
  • Sky: Overcast in the morning, clearer skies in the second half of the day
  • Water: Calm

Boats/Visitors:

Greg came again on Tuesday to bring us more water, we get a few hundred litres per load so our main water tank is over half full again. There has been a steady trickle of tour/whale watching boats, approximately 10-15 per day.

Ecological:

The two moulting elephant seals are still here, and they appear to be in less pain and are doing well.

The seagulls continue to get more and more aggressive, we’ve noticed that their eggs go missing. Yesterday, near the main path to the jetty there was a nest containing one egg and a territorial pair of gulls. Today, they are off the nest and the egg is missing.

Near desalination building we found a great example of what appears to be Gladiolus Imbricatus in bloom. According to a previous log post by Garry Fletcher: “Originally from south-eastern Europe/Turkey, it was introduced in the garden of an early lightkeeper and has been growing unattended here for over 50 years.”

While doing our daily seawater salinity and temperature sample, we were able to get a great picture of two sea lions on the jetty that were basking in the evening sun.

Polygonum aviculare: prostrate knotweed – The Race Rocks Taxonomy

knotweed

Polygonum aviculare

I noticed a particularly thriving population of the invasive prostrate knotweed this spring . It is typically successful in heavily compacted areas and adjacent to the sidewalks. Also it is probably not  favoured by Canada geese, as with most of the successful invasive species on the island.
