Cormorant Update 2018

The Double Crested Cormorant are back to the nesting tree. As of Feb 28th (the last time I checked) they have yet to reoccupy the tree they colonized last year above the playground next to the Rotary Nature Center.

You can get some close up time with the cormorants down on the channel, where they are often hunting on one tide or another.

They are wary of people and will often swim away, but sometimes if you are still enough, you’ll find them right beneath you — as in the photo below. Trailing bubbles as it searched the wall growth. It came up with a fish shortly after.

The prey was little silversides – one little school circling in the shallows, no doubt wary of the birds in the water nearby.

March 2nd update on the Rotary Nature Center

A couple of things happened this week.

One was an ad-hoc meeting organized by Katie Noonan and Stephen Cochrane (Wed 3/28/2018). We met at the Bellevue Club and talked about a range of issues, and identified a few things to look into, and talked about arranging visits to other Nature Centers in the area. We also had a little bit of heads up on the new below.

Friday’s update from Karis Griffin at OPRYD had some exiting news (3/2/2018):

Dear Community Partners,

I’m excited to update you on the progress we are making on the Rotary Nature Center.

We have retained the consulting services of Alan Briskin, a resident of Oakland and a facilitator of multi sector collaborative initiatives. To prepare Alan for the work ahead, he will be meeting with a core group, I will also be included in this group. Our task is to develop a process for a shared vision and an initial community gathering.

One of the key challenges and opportunities will be creating a Center that addresses diverse needs and interests from scratch. We must have a shared vision to do this.

Although there is currently no dedicated funding for programming, we believe it is possible to invite individuals, volunteers, and organizations to sponsor programs based on cost recovery and creative funding initiatives.

This communication is sent on a weekly basis to keep you updated on the Rotary Nature Center project. We thank you for your continued patience and support.

We anticipate that we will need to move the community meeting towards the end of the month or the first week in April.

Again, thank you for your patience. We hope that all of you are as excited as we are.

Facilitator being engaged

The past couple weeks, the Oakland Parks, Recreation, and Youth Development Department (OPRYD) has been working to hire and contract with a facilitator to lead the process for the renewed Rotary Nature Center. An individual has been selected.
I don’t have the name of the individual on hand. Today’s update from OPYRD said: “little to report this week… still in the process of finalizing our contract with a facilitator.” They are also (in conjunction with some of our allies) “planning to visit a few nature sites in the area.”
This was a suggestion that came out of a meeting organized this past week at the Lake Chalet. The meeting was an ad hoc one meant to keep people talking and thinking on our hopes and dreams for the center. We were happy to have a couple representatives from the city attend, from OPRYD and Councilmember MacElhaney’s office.
Here’s the full update if you care to read:

A Center Piece of Lake Merritt

A follow up from the Jan 24th meeting, Karis Griffin from Oakland Parks, Recreation, and Youth Development details how they are currently moving forward. They are selecting someone to facilitate the process with a goal “to create a new Rotary Nature Center that is the center piece of Lake Merritt, the nature-oriented learning institution it was destined to be.”

Met and Greeted

January 24th, 2018, some 60+ people came out to the Lake Merritt Sailboat House on very rainy night to talk about the Rotary Nature Center and what it might become at an Oakland Parks, Recreation, and Youth Development (OPRYD) “Meet & Greet”.

OPRYD was represented by Nicholas Williams, Karis Griffin (along with others like Dianne Boyd, and some the remaining  staff of the Center, Leanne and Michelle) . The  audience represented a wide swath of neighbors and organizations working around the lake: eg The Rotary Club, The Lake Merritt Breakfast Club, Measure DD Committee, Lake Merritt Institute, Oakland Museum of California, our group, (Community for Lake Merritt), Alameda Beekeepers, Golden Gate Audubon, Oakland Beautification Council, Insect Sciences Museum of California, California Center for Natural History, and more There were scientists, illustrators, naturalists, interested neighbors, and a kid who got her momto come.

We’d been gathering our allies through our petition, social posts, and emails, to allied groups. C.J. Hirschfield of the Rotary Club, and Jennie Gerard of Weed Warriors and Lake Merritt Advocates in particular deserve much thanks for their efforts). A huge shoutout to our board member Katie Noonan for her efforts to get people interested and involved.

The meeting itself was simple, Nicholas and Karis opened and answered some questions about the closure and the base level plans. Jeri Martinez from Alameda Beekeepers talked about the state of the beehive from the Center  which currently resides in Jeri’s backyard, waiting for the right time to return to their queendom at the Center. Cindy Margulis from Golden Gate Audubon gave an update on the heron colony and plans to attract them back to the lake. She also gave an impassioned coda as to why the Center is so important.

From there we talked a little about the process… next step for the larger community, a meeting Saturday March 17th, 2018 for people to propose projects for the Rotary Nature Center. In between that time, the city will be hiring a facilitator and creating a committee to come up with a strategic framework.

Nicholas said he want-s to honor the original vision of the Center, to protect the tradition with a 2018 spin. When pressed he assured the crowd that it will always be a Nature Center

OPRYD seems interested in taking guidance from the community in planning the future of the Center. We hope we will see continued communication from staff on how things are progressing


  • There’s a lot of work to do.
  • Lots of challenges remain.
  • We have a community and staff who are ready and willing to be engaged.
  • Stay tuned for more about the March 17th meeting and how to keep involved!
  • Sign up to stay in touch!

The Channel

The Lake Merritt channel is not pristine land. it has over the years been subject to all sorts of development, and (as the picture at top shows) downright defilement.

Today, as of 2017, we are closer to its natural state then we have been for over 150 years. The end of the channel, near where the stadium is to be built is perhaps closest still to this picture of development and defilement. 880 runs overhead. A defunct poorly fenced bridge underneath that littered with trash. Train tracks further on run mere feet from the tide. A large pipeline crosses it, next to the tracks and the new Embarcadero bridge construction is beyond that.  Further towards the lake, a tide gate and pumping station sits underneath where East 8th meets 7th. BART runs somewhere beneath.

You might notice the garbage collecting on tide gate grills. Or the homeless regulars. If you’re up earlier you’ll find people doing Taichi or Qigong excercises. Parks and Peralta maintenance people buzz by. Cop cars sometimes congregate under 880. Fisherman stand patiently on the banks casting for Striped Bass. Gardners work the in the Laney community garden.

You might notice the birds. Gulls dropping shells on the pedestrian bridge by Peralta, a squad of cormorants working the channel, egrets stalking the sides. If you go there often, you might notice that their numbers change fluctuate, species come and go. A kingfisher chitters by; an osprey snags a branch for its nest; a raven bullies a hawk, crows bully the raven, a Mountain Bluebird peers out of a nesting box, a ground squirrel pops up from below, Buffleheads bob and weave, Coots squeak, Canada Geese lead their goslings, Goldeneyes dive.

If your lucky, you might peer into the water and see a bat ray grace its way through the water, or see a halibut darts by, or fins a school of anchovies wave back and forth at the tide gate, a snowy egret perching on the tide gate waiting to snag the unlucky.

In the winder birds dot the channel from its opening to the lake. It is the tide that carries them, and everything underneath them back and forth from Bay to Lake, Lake to Bay. I overhear people all the time around the lake wondering about the channel, surprised that our lake is not a lake, making fun of the lake birds for being plastic eating birds, or enjoying explaining that our lake is not a lake.

People peer over the bridges, stop to look. Or don’t, they keep talking to their friends, they keep running, walking, talking. The city has spent nearly $200 million dollars, in part, to make it a place that people want to come and spend time by it.

Opposed to the Stadium

We at Community for Lake Merritt think that it is great that the A’s have decided to stay in Oakland, but we have serious concerns along with others over the potential placement of the new stadium on the Peralta property along the Lake Merritt channel. (If you want a good round up of all the concerns about the lake in this neighborhood, look to the East Bay Express series of articles: “Laney or Bust”)

We understand why the owners want to move near the lake. Since 2012 and the passage of Measure DD, the city of Oakland has spent (and is still spending) 198 million dollars and countless person hours on the lake and its environs. And it shows! The opening of the channel is part of these improvements, and is vital to the health of the lake.

The tides that flow up and down that stretch bring the Bay to Oakland, cleanse the lake, and bring birds, bat rays, anchovies, striped bass, and lots of fish and invertebrates. This is an unique feature of Oakland — not many cities have a slough and a wildlife refuge at their heart.

Just the other day, across from where the stadium would sit, I walked the bank and saw a large striped bass in the water, at my feet more or less. I stopped to watch and it swam off languidly, disappearing into the water. How would the stadium construction deal with the channel, what would it stir up, would it be hardscaped? What birds would the stadium attract and what would it deter.

And then the thousands of people will likely bring erosion, and litter. I would love to see more people exploring the channel. Some in the stadium crown would likely enjoy it, but for most it would be a path. Nowadays it is just me, people doing exercise or gardening by Laney, some homeless, and some fishermen. Sundays are a little busier with the swap meet in the Laney parking lot. There’s much more that could be done to make it accessible, keep it beautiful, and connect it to other paths and trails to Jack London and Brooklyn Basin. A stadium might do these things for its own ends.

And to be clear, this not a NIMBY rejection (I personally would take the 2002 Uptown version in my backyard with no issue!), but a desire to protect the potential long term vision of what the lake and its channel could offer to all of Oakland residents.


Spineless Wonders of Lake Merritt

…or, more technically, invertebrates…

Lake Merritt is justly famous for the many species of birds that overwinter on the lake . The occasional appearance of a sea lion or river otter makes headlines but did you know that the lake is also home to a great variety of micro-charismatic critters?

The most obvious (and perhaps least charismatic?) are the mussels that line the edges of the lake. They stick out in a low tide. Gulls love to feed on them — you may often see a gull with one in its bill. Gulls will also deliberately drop a closed mussel onto the pavement to open the shell and get at the meaty interior. Take a look inside an open mussel shell and there you will find yet other organisms.

Mussel inside

Less obvious but more important for the food chain is the plankton in the lake. Plankton consists of tiny critters that one needs a microscope to see and can include diatoms, protozoans, small crustaceans, and the eggs and larval stages of larger animals. The Nature Center (when we reopen again!) has microscopes that school groups and other visitors can use to get an idea of the diversity of life in the lake.


The most “famous” invertebrate at the lake is a new kind of beach hopper discovered many years ago by a 14 year old boy, Jim Carlson, who went to great lengths to find out what it was.  (You can find his story at Bay Nature Magazine). Like most of the rest of the lake’s flora and fauna this “bug” probably was introduced on the hull of a ship. No one could identify this critter and it turned out to be a new species dubbed Transorchestia enigmatica. These beach hoppers may still be present on the small stretch of remaining beach near the bandstand. See if you can find one. You’ll find a more typical species of beach hopper along the channel.


My all time favorite invertebrate — seen at the lake back in 2015 — was a family of sea hares hanging out under the pedestrian bridge. Sea hares are related to octopuses and can eject a stream of ink to hide from potential predators.

Take a walk around the lake at low tide and see what you can find in the water.

Lake Merritt Advocates

A couple weeks ago (November 13th, 2017), our group joined a whole slew of other groups who exist around the lake at the Lawn Bowling clubhouse to learn about each other and how we can support each other. This included people from some of the institutions around the lake: The Gardens, Fairyland, the Camron-Sanford House; there were environmental advocates from Lake Merritt Institute, Audubon, Laney College. There was the Lake Merritt Breakfast Club, Lake Merritt Band, and the Lake Merritt runners, city employees, and interested citizens.

We were all a little amazed that there were so many the creation of a an individual originally interested in showing off his awesome photography, but grew to be a resource for all the goings on at the lake. This will be our — the Lake Merritt Advocates — hub, the place you can find to find a fun event, or a volunteer activity. We’ll be sharing our opportunities there as well.

We hope that the advocates as a whole will provide a place where we can share larger concerns, and work together with the City and their departments to make the Lake that much more of a great place to be.

Where have the Eared Grebe’s gone?

One of my favorite winter residents of the lake is the Eared Grebe. It’s a small diving water bird (most closely related to Flamingos) that is flightless much of the year. The males turn into demonic looking birds just before they head out for mating season in the Spring. If your lucky, you can also sometimes glimpse their forays underwater. Their favorite food seems to be the the Bay Pipefish which seem to provide the grebes a run for their money.

The pipefish seem to be getting a reprieve this year with no Eared Grebe’s in their “traditional” hunting grounds (aka the spots I’ve seen them in over the past few years). I had seen one Eared Grebe on the lake near the bird islands earlier this year, but I have not seen it since. Things have been left to the Pied-billed Grebes, an equally cute species but which seems to mostly confine itself to the the refuge area on the northern side of the lake. Eared Grebes in my observations have favorite spots dotted around the lake. Last year, I’d remarked a trio showing up by the pedestrian bridge at the Southern end of the lake in early October where they could be reliably found for months after.

There seems to have been some e-Bird sitings over the last couple of days, so perhaps they are still to arrive. I did note, however, the week they arrived last year would have coincided with the fires in Sonoma and Napa. With the air quality so bad, I wonder if the birds thought better of flight, and decided to stick it out where they are. According to my Bay Area Birds (David Lukas, 2012), Eared Grebe’s make great use of the South Bay Salt Ponds, and nest down in the Hayward.

Data in my various sources of citizen science data (iNaturalist and eBird) seems too thin to make any kind of call on that hypothesis. And at the end of the day, I hope they still show up.
