The volunteer hours from 2012 have been and the results are very impressive!
Over the course of the year, from the drop-in volunteer days we had an 118 volunteers show up to garden, and these gardeners contributed 5357.75 hours. The total from the group work days came to 1172 hours, the result of 530 people from 42 different work parties.
Together, the final year total is 6529.75! This brings our year to date total to 43065 hours. Certainly, an amazing achievement that we are very proud of. As we begin our 10th year of gardening on the Rock, we will easily surpass the 50000 mark in volunteer hours by the end of the year.
Thank you to all the volunteers for another productive year in the gardens!

It’s a fun time to be a volunteer in the gardens with working on the big projects for this winter. Many of the volunteers got hooked on gardening on the Rock because of the initial uncovering and ‘discovering’ of the forgotten gardens. For people that loves getting dirty and feeling like you are making a difference – this is the time to get involved!
The lawn, which is being prepared to be planted in the Fall of 2013 with native grasses, has become neglected and the ‘green’ of the lawn is all from non-native grasses and oxalis. But even this green vegetation died during the dry summer, leaving a barren looking backdrop to the manicured gardens.
To prepare the area, the first layer of mulch layering has been laid down, and to my dismay, birds have pecked their way through the compost and the cardboard to reach the soil, allowing light to the oxalis that we are trying to suffocate. Those darn birds! I’m hoping to place another layer of cardboard and mulch in the coming week.
In the meantime, the volunteer crew is working away at clearing the forty plus years of overgrowth on the north end of the historic lawn. The overgrowth is being tackled from all sides, and today we finally made it to the base of the large Albizia tree that is in the middle. Another few hours were spent digging up ivy roots and before we knew it, it was 2pm already! As we worked, one of the volunteers wondered out loud if the author of Jack in the Bean Stock was a gardener that had pulled ivy. Some of the ivy shoots were easily 20 feet long!
Clearing ivy is pretty addictive – the work is slow but methodical.
The Federal Prison on Alcatraz was meant for the ‘worst of the worst’. Inmates only got sent to Alcatraz because they were behaving badly at another prison; in a way, they had to earn their way to Alcatraz.
But what if you are a plant? And you are misbehaving? And you are already on Alcatraz?
This seems to be the case with our Agaves.
While the island was operating as a military fortress to protect the Bay, and later as a military prison, Agave americana were brought to the island in the early 1920s in attempts to landscape the island. The plant proved to be ideal for growing in the dry, rocky soil with little water or care. But this plant has a defense mechanism of its own. Perhaps it is not commonly known, but Agaves can cause skin irritations when the sap comes into contact with people’s skin.
While not everyone is afflicted, a few of my volunteers have had reactions to being poked by the thorns or have developed a skin reaction with itching and blistering because of the sap. The sap contains calcium oxalate crystals, acrid oils, saponins, and other compounds, but it seems the calcium oxalate is responsible for the irritation.
A quick search on Wikipedia found that – “The juice from many species of agave can cause acute contact dermatitis. It will produce reddening and blistering lasting one to two weeks. Episodes of itching may recur up to a year thereafter, even though there is no longer a visible rash. Irritation is, in part, caused by calcium oxalate raphides. Dried parts of the plants can be handled with bare hands with little or no effect. If the skin is pierced deeply enough by the needle-like ends of the leaf from a vigorously growing plant, this can also cause blood vessels in the surrounding area to erupt and an area some 6–7 cm across appear to be bruised. This may last up to two to three weeks.”
There are three types of Agaves on the
island – Agave americana, which has established itself on hillsides and needs minimal care, while in the gardens, we have introduced Agave attenuata and Agave parryi. The Agave attenuata is my favorite! Not surprisingly, it has smooth leaves and no thorns. The Agave parryi, has a different story. This low growing blue leaved succulent has black spines along the margins of the leaves and the tip – very nice to look at, but not nice to weed around.
Like a bad sibling, this plant has been cursed at more often than any other plant on the island, and is one step away from the compost pile after pricking the volunteer that stewards the succulent slope. Instead of being sent to ‘D’ Block aka, the compost pile, Agave parryi will be isolated on a slope outside of the rec yard, far away from any well-meaning hands. With a view of the Golden Gate and city, Agave parryi, can think long and hard about what it has done! Or perhaps, it will think ‘alone at last, now I can enjoy the view’.
Even though Alcatraz is a rock, greywackle sandstone to be exact, erosion is taking its toll.
Originally, the island had two summits that were blasted down by the military when the island was used as a fortress and later a military prison. Steep cliffs were created and the roadways that we walk today were carved into the hillsides. The Commander of the Army, and later, the Warden of the Federal Prison, picked the best vantage point to build his home on Alcatraz, of course, he picked the top of the island overlooking the Parade Ground.
The cliff that the Warden’s House is perched upon has been slowly crumbling over the past few decades. This month, work was started to stabilize the cliff with placing shotcrete, to preserve the cliff and the historic home. Shotcrete is a mortar that is more dense, homogenous, stronger and waterproof compared to concrete. Shotcrete is sprayed onto the cliff, usually over a mesh, through a hose at high speed, so it can even be applied to vertical surfaces – making it a great choice to stabilize cliffs.
Workers first dangled over the cliff to remove vegetation and loose rock. A huge pile of Agave americana soon accumulated. These plants are truly amazing to cling to rock.
This week, the crew color coded the locations for placement of dowels that would be used to secure the mesh and bond the shotcrete (white) to the cliff face, weep holes to provide drainage (blue) and the locations of deeper rock bolts (orange).
The work to stabilize the cliff will continue to the end of January. Visitors can watch the work progress and it is pretty interesting to see preservation of this historic landmark in progress.
I’ll let you in on a little secret – now is the best time to visit Alcatraz. The Thanksgiving crowds have gone home and the holiday season hasn’t started yet. The ferries are not packed, which means you can buy a ticket the day of. And even better, the island is lush and green, the daffodils are blooming and the hummingbirds are zipping around.
The island feels almost tranquil, especially the gardens. Normally quiet, even during the summer, the Prisoner Gardens on the west side of the island typically only sees visitors when the weather is particularly beautiful. In the winter, it is possible to work for hours in the gardens without saying hello to anyone. So, I had a bit of a surprise while working yesterday on the west side – the gardens actually felt busy. I wondered what was going on and then I realized – people were on the wrong side of the gate – in the CLOSED area!
Following the stream of people, I entered the Laundry Building and spoke to the National Park Service Intern, Nora. It seems like the Park decided to open the building doors and let visitors experience this normally ‘off limits’ shortcut.
This additional visitor access is pretty special – not only do visitors get to see more of the island, but now they can walk around the island through the Laundry Building instead of backtracking. The visitors are also walking in the steps of the inmates – walking through the gardens and seeing the city in the distance while on their way to work in the Laundry Building.
The cliché of being so close yet so far, probably never had a better example.
Even though you will not need to book ahead to visit during the winter months, don’t leave it until the last minute. This area will close for February 1 as Brandt’s Cormorants return to nest in a nearby area.
This week the Garden Conservancy celebrated ten years of our West Coast Council programs. We also gathered to honor Antonia Adezio, our President, who is stepping down in December.
We reflected on our goal of having a bigger impact on West Coast gardeners. Looking around the room Wednesday evening at the close-knit community of gardeners, the Garden Conservancy has certainly excelled at this. In a way, it reminded me of what Freddie Riechel, the first secretary to the Warden challenged himself with when he took on caring for the gardens on Alcatraz back in 1933. Riechel reached out to expert horticulturists to keep the tradition of gardening on the Rock going. The Garden Conservancy has done the same, seeking advice from the West Coast Council and professionals to create educational programs to connect experts to local gardeners and to further develop preservation project gardens.
Antonia joined the newly founded Garden Conservancy in 1989 at the request of Frank Cabot. With the organization firmly established on the East Coast, the board of directors determined that in 202, the organization was ready to have a regional office based in San Francisco. Shortly after, the Garden Conservancy was enticed by the National Park Service and the Golden Gate National Parks Conservancy to form a partnership to restore the Gardens of Alcatraz. The neglected historic gardens quickly became a passion for Antonia. As part of the evening’s ceremonies, I had the honor to present a brief history of our work on the island and to highlight our accomplishments with bringing the gardens back to life.
Antonia’s leadership throughout her time with the Conservancy has shaped the success , especially with Alcatraz, and her vision will be continued as we carry on. I like to think that every garden holds onto some characteristic of their caretakers, even as the caretakers move on. I see this especially in the old gardens on Alcatraz – the surviving apple trees that still bear fruit, the inmate built terraces, and perhaps the greatest mark left – the decision by the Garden Conservancy get involved to restore the gardens for the future enjoyment for all.
I’m constantly learning new things about gardening and Alcatraz, even after working in the gardens for close to six years now. On a recent trip to pick up my order for more volunteer shirts, I finally met David, president of Plum, a company in Emeryville that prints our t-shirts and hoodies. David invited me to take a look behind-the-scenes to see the screen printing process.
David has owned the business for 35 years, first starting to print shirts for museums. A connection then led to the Golden Gate National Parks Conservancy, the non-profit organization that manages the bookstores throughout the Golden Gate National Recreation Area. In fact, sweatshirts for Muir Woods had just come off the line. Plum also prints shirts for various humane organizations.
The screen printing is fairly simple
and hasn’t changed that much since the Chinese invented the process hundreds of years ago. Garments are placed on an automatic rotary printer, with each arm having a screen. The first step in the process is to separate each color in the design to exactly abut each adjacent color so that the colors do not actually touch each other; each color segment is printed separately. This step is now done on the computer, but in the early days of the company each color was hand cut. Each color is then shot on its own screen. Setting up the screens so that this can be achieved is a critical part of the screen printing process. The attached screen forms open areas of mesh that transfer ink which can be pressed through the mesh as a sharp-edged image onto the garment. A fill blade or squeegee is moved across the screen stencil, forcing ink into the mesh openings. The garment is then taken off and is placed on a drying conveyor belt. Depending on the types of inks used, the drier is set at 325 Fahrenheit and dries the shirts in one to four minutes.
David estimates that that they can print over two thousand shirts on one machine in one day!
Elliot Michener, our inmate gardener, would surely have been impressed with the setup. Elliot was a skilled printer himself at a newspaper; or perhaps he was not that skilled afterall, as he tried his hand at counterfeiting money but obviously was caught.
Loosely translated, Alcatraz means ‘strange looking seabird’ in Spanish. Even today, the island is a bird haven. This time of year, the cacophony of the Western gulls has left and the background noises of the island become heard. The cheerful chirping of songbirds is apparent, especially along the west road that takes visitors through the inmate gardens. Anna’s hummingbirds are zipping around while black Phoebes can be seen perched on branch shrubs.
Speaking with the National Park Service wildlife biologist, Victoria Seher, she updated me on the latest songbird activity: “For many years the Natural Resource office did a monthly Alcatraz Bird Census of the island during the winter months, however, it hadn’t been done for several years. This year we decided to resurrect the count, modifying the protocols a bit. The island bird walks are conducted 2 – 3 times per month from October through January. Waterbird docents from the previous season are helping with the counts, but we are accepting new volunteers as well. The counts start at 9am on the dock and follow the Agave Trail up the stairs to the Parade Ground, around the rubble piles, behind Building 64 and up the path to the cell house, down the west road, through the Laundry Building and down the north road back to the dock. The counts have been about 2.5 – 3 hours long and we travel about 1 mile. All birds are counted (even the ones we see in the water or flying overhead).”
Victoria and her keen observers counted 26 different species of birds last week, a surprise count even for themselves.
Reading through the suspect list, I mean, bird list, I couldn’t help but wonder; which one of these guys is eating my marigolds and chrysanthemums? The marigold nibbling started innocently enough – first just the orange flowers, but next it was the orange flowers, then all the leaves disappeared. The chrysanthemums also proved to be a tasty treat – all the flower buds were gone in a few days.
The gardens are providing much more than just enjoyment and beauty for visitors, the gardens also provide food and shelter to the birds. The benefit of the gardens to the birds is, in a strange parallel, very similar to what the Federal Bureau of Prisons provided for the inmates. Regulation Number 5 stated “You are entitled to food, clothing, shelter, and medical attention. Anything else that you get is a privilege.” The gardens stop short of providing clothing for the birds but with Victoria with her team of volunteers and interns keeping watch over the birds, they do receive medical attention if needed.
Be sure to visit the island in the next month to witness these special jail birds.
Gardens are all about change – hopefully for the better, but they are never still. With any change, it can almost be expected to face challenges; and this is especially true when you are gardening on Alcatraz.
This week, the gardens saw the installation of a new pipe railing, albeit a pipe rail that was historically there, but had long ago disappeared. The Officers’ Row gardens, opened to the visitors on mid-day Wednesdays suddenly had the new addition seemingly overnight. The approval and installation of the pipe rail was the easy part; getting the pipe rail to the island proved to be the real challenge.
The pipe rail is evident in several photos from the Federal Penitentiary days, and with the obvious hazard, it was approved by the National Park Service review board fairly quickly.
The metal pipe rail was assembled off-site by Heavy Metal Iron and was planned to be brought to the island on an early morning boat. However, at the last moment, the 14’section was denied passage and another plan had to be drawn up. A second attempt was made. This time, the railing was scheduled to be on the early morning barge; but was hampered by the landing at Pier 33 being repaved. The third attempt took advantage of the monthly barge that sails out of Pier 50 and the railing was delivered safe and sound. Success!
Once the railing was on the island, it still had to be hauled up the switchbacks to the gardens. The guys had planned ahead and had brought a dolly to support the railing as they walked up the hill, and the exercise proved to be a good workout.
Installing the railing was pretty simple – coring the concrete to sink the posts, double checking that the railing was sitting level, filing the metal to have a snug fit and then a quick set mortar was used to hold the railing posts in place.
The railing looks like it has always been there and I’m sure the seagulls will be happy to christen it when they return in February.
Instead of being asked gardening
questions, a common question visitors and locals alike have been asking is ‘What is that white covered tower on the island?’ The tower in question is the water tower that has been wrapped in protective plastic while repair work has been done.
The water tower was first built in 1940–41 primarily to hold fresh water that would be used for laundry services. The Federal penitentiary provided laundry service for the Army and inmates were put to work doing laundry. The sea air and wind have been punishing the tower ever since.
For the past year, workers have been busy removing rust, safely removing lead paint, repairing the iron work, and painting the structure with a coat of primer (Macropoxy 646) and two coats of finish paint (Sher-Cryl), the same paint that is used for painting the Golden Gate Bridge, except the water tower is not done in ‘International Orange’.
The work began with the construction of the scaffolding last October 24, 2011 and it was amazing to just watch the ant-like workers build up the scaffolding. The scaffolding was then wrapped in a heavy duty white plastic tarp for a few reasons – reduce disturbance of nearby nesting seabirds, safety of the workers and lead abatement. In a funny way, locals that have gazed at the outline of the island for years suddenly forgot what was there before it was wrapped.
This past week, I was invited for a trip up to the top of the water tower, somewhere I had never been before on the island! Walking into the tent at the bottom, I had to smile seeing a clump of Chasmanthe emerging; ever resilient, this island survivor never gives up.
On a windless day, walking up the levels of scaffolding was easy and the plastic wrapping hid just how far off the ground I was. Apparently, on a windy day, the whole structure hums.
Kyle Winn, project superintendent for MTM Builders Inc. explained the more fascinating parts of the repair work.
How many workers on the crew? 11 to erect the scaffolding, 5 to do the steel repairs and 3 to paint the structure.
How much original metal is left on the structure? Approximately 85% of the steel is original.
Where did the new steel come from? Kentucky.
How many gallons of paint were used? 350 gallons.
How long did it take to paint? 2 months.
How much did the repairs cost? $1.541 million.
The catwalk around the top of the tower is still original and Kyle was impressed with the quality of steel used when the tower was first constructed. The walking platform is about ½ inch in thickness and solid, not showing any signs of rust. Kyle pointed out the name of the company where the original steel was made – Tennessee. New construction consisted of a new roof along with the supporting top one foot of the water tank itself.
The repaired tower will not hold any water,
but its reconstruction was important as the water tower contributes to the National Historic Landmark that Alcatraz is. The Native American graffiti is also an important part of the island’s history and has been repainted.
The scaffolding is already coming down and the new water tower will be unveiled!
