You might think that beekeeping in prisons is a nice idea, but not a big idea: maybe it’s a small, fanciful project that would crop up here or there. Not the case!

In Washington State prisons alone, we already have seven beekeeping programs up and running, and at least three more are in the works. Beekeeping is also in the prison at Joint Base Lewis-McChord, and many corrections facilities nationwide, including Georgia, Maryland, Illinois, Oregon, Florida, Nebraska, and LA County. Beekeeping programs can also be found in foreign prisons like England, New Zealand, Italy, and France. We’ve been contacted by prisons interested in beekeeping in Massachusetts, Albania, and Canada!

Outside of prison, reentry programs, like Sweet Beginnings in Chicago, offer meaningful work experience. The founding executive director of Sweet Beginnings, Brenda Palms Barber, found that “Fewer than 4% of Sweet Beginnings participants go back into the criminal justice system, compared with the national average of more than 65% and the Illinois average of 55%.” How amazing is that?

Adding to the honeybee focus are countless prison gardens that are accessible to many types of pollinators: beds of flowers and herbs, small-scale vegetable production, and full-scale farms. Corrections facilities typically don’t use any chemical pesticides, so don’t contain the systemic poisons that threaten foraging pollinators; prison plantings are helping to rebuild pollinator habitat by offering a safe food supply. Some prisons add habitat structures for native pollinators, such as mason bee boxes at Coyote Ridge Corrections Center (see photo) and a literal-log delivered to the retention pond at Airway Heights Corrections Center.

These programs tap into the many therapeutic benefits of working with nature, which has been widely documented in scientific research. Working with honeybees is particularly soothing; it’s impossible to get good results with bees without calming down. Both inmates and staff sorely need relief from prison stresses, and nature programs can be a place of refuge and recharge.

Also these programs provide a way for inmates to “give back ” to communities and the environment. In recent decades, pollinators have been dying at a frightening rate, putting our food sources in jeopardy: we depend on pollinators for more than 30% of human food and drink. Generally, nearly all plants with flowers need pollinators; 85% depend on insects for their reproduction! We need healthy hives to conserve and restore bee populations. In 2015, pollinator health was declared a national priority; as a hobby or career, beekeeping is has societal recognition and value. This is no fanciful endeavor—we need bees to thrive so that we can thrive.

In Washington, we are ramping up to a full-day Summit for Beekeeping in Prisons, to be hosted by Washington Corrections Center for Woman on March 3rd. More than 100 people are registered, and they will come from all 12 Washington prisons, the Evergreen State College, various non-profits and community groups, and multiple beekeeping associations, including the statewide association that oversees beekeeping certification. A major bonus of holding the summit inside a prison is that incarcerated beekeepers will be able to participate. All partners will share best practices, future prison beekeeping plans, safety ideas, community outreach plans, and pollinator health knowledge. We can’t wait to hear what great ideas and thoughts come from our many, fantastic partners!

Each program depends on partnerships among incarcerated individuals, corrections staff, and expert beekeepers. They are united in learning about and tending to something beautiful, complex, and a little bit scary…until it becomes second nature.

Last week, SPP’s Science and Sustainability Lecture at Stafford Creek Corrections Center brought Giovanni Galarza and two snakes into the classroom. Giovanni is an Evergreen student and herpetology enthusiast, and he gave an exceptionally compelling presentation. Thank you to Ricky Osborne for his powers of photography—seeing these images is almost as good as being there!

Sierra, a Desert Kingsnake, investigates his enclosure before the lecture. Desert Kingsnakes are nonvenomous snakes native to the Southwestern United States, and are immune to the venom of Rattlesnakes which they prey on.

A student takes a closer look at Sierra the Kingsnake.

Giovanni passes around Brandy, a young Corn Snake, for students to touch.

Corn Snakes like Brandy are very docile, making it easy for everyone to get a special, hands-on experience.

Giovanni assists a student with proper handling of the Corn Snake.

For many in the audience, this was their first encounter with live snakes. Everybody seemed to gain a new appreciation for these beautiful and often misunderstood creatures.

In SPP’s new Emergent Vegetation Conservation Nursery at Stafford Creek Corrections Center, we are growing native wetland plants in coconut fiber mats for wetland restoration projects. The program relies on a team effort from incarcerated technicians, prison maintenance staff, Evergreen’s program coordinators and managers, Joint Base Lewis McChord, the Center for Natural Lands Management, Washington Department of Fish and Wildlife and the United States Fish and Wildlife. All have done an amazing job meeting the challenges of the innovative program’s technical demands.

Coconut fiber mats, or “coir” mats, are commonly used in restoration for erosion control and suppression of weeds such as reed canarygrass. We are pre-planting them with wetland sedges and rushes, giving those beneficial plants a head start under nursery conditions. These plant types are known as “emergent” for their ability to grow through—emerge from—the water’s surface. Our hope is that the plants will be able to out-compete weeds and provide superior habitat for wildlife, such as the endangered Oregon spotted frog.

To grow the plants, we are using an aquaponics system. Two large fish tanks contain more than 100 koi, which produce waste that the plants use as nutrients. The water from the fish tanks circulates through the plant beds and then back to the fish tanks to pick up additional nutrients. The plants grow directly into the coir mats and do not need soil. By using an aquaponics system, we save water and reduce the need to weed or fertilize the plants.

We installed the first mats at Joint Base Lewis McChord in early November, and plan to have new mats ready in just a couple of months.

After a few months of waiting, Cedar Creek and Larch Corrections Centers have each received a new batch of turtles for their Western Pond Turtle Rehabilitation Programs!

One particularly adorable turtle who recently arrived at Cedar Creek.

During this waiting period, the turtles received acute care for shell disease, which included antibiotics, antifungal medication and shell surgery. The turtles that have arrived have completed treatments and just need watchful eyes and extra time to heal and wait out the winter months. The technicians provide all of this and more. They were excited to have new turtles to care for and prep for their eventual release back into the wild!

I delivered the turtles with the help of WDFW biologist, Emily Butler, to Cedar Creek on Monday November 1st and just this Monday Larch received their turtles. We were honored to have Dr. Matt Brooks, a nutritionist from the Oregon Zoo, to help us transport the turtles to Larch. This was Dr. Brooks’ first visit to the turtle program. He is helping us to improve turtle health by increasing the nutritional value of their diets. We are so thankful for his help, as we are always looking for ways to improve the quality of care provided to these endangered turtles. Thank you Dr. Brooks!

Co-Authored by Western Pond Turtle Technicians Taylour Eldridge and William Anglemyer

On Monday October 3rd, turtle 4176 was released from the Turtle Rehabilitation program at Cedar Creek Corrections Center . She had been there for quite some time—about 4 months, with a month long intermission at PAWS wildlife rehabilitation center in Lynnwood, WA—then back for another 4 months. She had suffered from seizure-like episodes and for awhile it looked like she wouldn’t be deemed releasable back into the wild. We had been worried, as people who have spent time in solitary confinement ourselves, that months in captivity would have a detrimental effect on her. So it was a great relief to finally load her into a container and board a van destined to deliver her to the Lakewood Western Pond Turtle Refuge.

When we arrived, we were met by Washington State Fish and Wildlife Biologist, Emily Butler. In addition to facilitating the turtle release, Ms. Butler showed us how the radio telemetry transmitters are attached to the turtles. We were then given a training on how to use the radio receivers and Ms. Butler took us to the area where the turtles lay their nests. She had hidden two mock (plastic) turtles with transmitters attached to the shells. We took turns using the radio receiver and the attached antenna to find the plastic turtles. We both found it quite difficult; it’s not even close to easy to use the radio telemetry equipment. But we were eventually successful in locating them–truthfully, we received some visual hints. We have a new-found respect for anyone who has to attempt to find turtle nests in this manner.

Apart from the experience making us much more aware of the very difficult work of finding nests, it was a great learning experience which gave us a new found appreciation for the hands-on work that goes on in the field—a part of the program we’d never been privy to before. We learned of the plethora of other activities that the biologists do every day to help with the recovery of this amazing species.

We both feel good about being part of the SPP Western Pond Turtle Rehabilitation Program and we cannot think of a more worthwhile job—especially as people in an incarceration setting. We’re looking forward to helping the next batch of turtles get through their healing process and seeing them released back into the wild. We hope the day will come soon when there are no more turtles that need help healing. Hopefully, the future will bring multitudes of healthy turtles living in their natural habitat.

Creative Illustrations for Monarch Butterfly Conservation

Drawing and art making are powerful tools to increase the ability to focus, relax, and develop creative problem solving in areas far beyond visual art. As an artist, illustrator and teacher, my experience working with students has illuminated the understanding that drawing teaches people to see. When we look closely in the way that illustration demands, we observe and comprehend the subtle details that make our subject significant and unique.

Teaching the art of the butterfly

We learn so much by looking closely, understanding, and representing. These were ideas I hoped to convey when planning a natural science illustration class as part of an internship with SPP for students at Airway Heights Correctional Center.

The illustration workshop was developed around the essential relationship between milkweed and Monarch butterflies and —most importantly—how creating artwork about this relationship can inspire understanding of core issues facing the imperiled Monarch butterfly and actions we can take to preserve and restore this species.

Studying the butterfly specimens

This internship project, pursued with support from SPP staff, the Endangered Species Coalition, Airway Heights, and other partners, centers on the proposal to develop a milkweed propagation site at the prison. The idea is to grow a species of milkweed, Asclepias speciosa, which is native to Washington State. Milkweed seed from plants grown in the prison would be collected by technicians for habitat restoration at designated sites near Spokane. The project goal would be to increase habitat for the Western population of the Monarch butterfly. Milkweed is the obligate host plant for Monarchs; eggs are laid on the plant and emergent caterpillars consume the leaves of the plants, developing toxicity which makes them undesirable to predators such as birds. Habitat where milkweed has historically grown has been destroyed due to pesticide use, changes in land use patterns, and other factors. Without milkweed, the only host plant for key lifecycle stages, the survival of Monarch butterflies is imperiled.

Inspiring message from an incarcerated artist: lifecycle of the Monarch

Sharing knowledge about this symbiotic relationship between butterfly and plant by creating illustrations with students and corrections staff at Airway Heights was inspiring. The workshop participants asked insightful questions, expressing concerns about how the loss of important pollinators such as Monarchs will impact other species, including humans. They saw the intricate detail of Monarch wing scales and milkweed leaves in specimens borrowed from the University of Washington. These observations were captured in detailed, creative colored pencil and graphite illustrations.

We talked about how drawing is a practice that takes patience and that mistakes made provide opportunities to reinforce skills. At the end, we viewed all of the work in a classroom gallery walk and shared what we noticed; a key observation was how everyone approached the project in their own way, some realistically, others adding words, some representing their ideas about how to protect these species. One of the most profound observations was how drawing and educational workshops like this allow students to feel reconnected to the community and themselves. It’s my hope that this connection will extend outward toward the development of a milkweed planting project and restoration of habitat for Monarchs, a species that so eloquently represents cycles of growth, transformation, and renewal.

Jeanne Dodds is a Teaching Artist, illustrator, and photographer who explores themes of connection and discord in the relationship between humans and the natural world. She is an incoming student with the fall 2016 MES cohort, and interned with SPP to research milkweed and Monarchs during summer quarter.

Jim Miles is a conservation nursery technician at SCCC. We bought a new picture microscope for the program, and gave Jim the task of documenting more than 40 different species of prairie plant seeds. Miles had shown an interest in earlier detail-oriented tasks such as data collection and plant tracking. His ability to efficiently and systematically organize, document, and store critical data and information sold me that he was the right person for this particular task.

I delivered the seeds to Miles in a small box full of little manila folders. Being the meticulous worker he is, he immediately began to alphabetized the folders and outline a documentation sheet to correspond with the photos which were saved on an SD card. Tediously, he aligned each seed on a ruler to measure its length and width. Some species, like Micranthes integrifolia, are smaller than cracked pepper, so it takes patience to place them where you want them. Miles took the initiative to photograph seeds with various backgrounds—this proved useful for identifying characteristics of each seed, providing differing levels of contrast and illumination. The effects were impressive and looked like they belonged in an art gallery.

Gaillardia aristata, blanketflower, is a colorful daisy-like flower of the prairie, but the seeds look like wolf heads.

On October 6th, SPP partners from Department of Corrections and The Evergreen State College gathered with representatives from Joint Base Lewis-McChord, Washington Department of Fish and Wildlife, Northwest Trek, and Woodland Park Zoo to release frogs into a Pierce County wetland. This marks the sixth season of the partnership raising federally-threatened Oregon spotted frogs at Cedar Creek Corrections Center (Cedar Creek). It was a joyous occasion as all the partners gathered to release frogs from the three rearing programs.This year Cedar Creek raised 167 frogs and they have raised a total of 879 frogs since the program started in 2009.

The program is likely to end while scientists focus on learning more about effective recovery strategies. The likely suspension of the program provides an opportunity to reflect on successes and the many contributors who have dedicated their time to this effort.

The Oregon Spotted Frog program is the first known prison animal conservation program in the United States. We were able to do this work because several key science partners were convinced that a collaborative program operated in prisons could contribute to species recovery. Special thanks to biologists Jim Lynch and Marc Hays for recognizing the potential of this program.

Since the program started, 13 inmate technicians have received herpetological training and education. SPP inmate technicians have matched the success of programs hosted at zoo facilities. The current technicians, Mr. Boysen and Mr. Anglemyer, have done excellent work!

Four corrections staff have served as the SPP Liaison for the program. Each of these staff have accepted this work in addition to their regular duties. Thanks to Ms. Sibley, the current program liaison—her time and dedication has been so important to program operation. Also, special thanks to Superintendent Doug Cole for years of enthusiastic support for the program.

Six graduate students from Evergreen’s Masters of Environmental Studies program have served as program coordinator. Each student makes important contributions and improvements to the program. Sadie Gilliom is the current program coordinator. Sadie’s program contributions have included science seminars, animal behavior studies, and updated outreach materials.

The Oregon Spotted Frog program at Cedar Creek paved the way for conservation programs in prisons. Through the success of this first program, collaborators proved conservation work can be done well in prisons, and that it can be rewarding for everyone involved.

As a result, new conservation programs have been started in Washington prisons and prisons in other states. SPP partners at Cedar Creek will continue caring for Western pond turtles, another species in need. Now that the frogs are gone we will be keeping an eye out for new science and sustainability programs to introduce to the prison. May these new programs be as successful as the frogs!

Flight of the Taylor’s Checkerspot Butterflies

By Christina Stalnaker, SPP Graduate Research Assistant and Roots of Success Coordinator

It was a smaller crowd than usual: two males fluttered around a single female. The lighting was ideal and temperature at just the right degree for a successful pairing. As these butterflies moved in their miniature habitat, two inmate technicians quietly watched to verify if they had a fruitful engagement. We had just entered the greenhouse of the Taylor’s checkerspot butterfly (TCB) captive rearing program at Mission Creek Corrections Center for Women on an early spring morning.

These butterflies were the first of their cohort to eclose, marking the beginning of TCB flight season. Eclosure is one of the final stages of a Taylor’s checkerspot butterfly’s life cycle—it occurs when the butterfly emerges from its cocoon. When the remaining butterflies join them in flight, the technicians will place two females and up to seven males in an insect habitat. Lindsey Hamilton, SPP’s TCB program coordinator, later explained to me that placing so many in the habitat at once ignites the male’s competitive behavior. In the wild, TCB males can be found next to a female pupa, waiting for her to eclose.

The technicians had been waiting for us to arrive at the prison’s greenhouse to “process” two more butterflies that had just completed eclosion. The word “process” is far too ordinary to describe this next step in caring for these beautiful, endangered butterflies. Upon emergence, the butterflies patiently wait in their tiny container for at least 24 hours before feeding on honey water and taking flight. I had never handled butterflies before and was pretty nervous. Elizabeth Louie, TCB inmate technician, proudly demonstrated how to handle and process the delicate insects. After she showed me exactly what to do from start to finish, I went on to process the second TCB on my own.

First, we recorded the ID number and color code. Next, we removed the mesh caging and the TCB from its insect cup, gently pinch its wings, and closely examined the butterfly to determine if it is a male or female. Mine was female; I could tell by looking at the tip of the abdomen. Females have a pointed tip at the end of their abdomen, whereas males’ are more rounded. After placing her on the balance, we recorded her weight. Swirling the end of a q-tip in the honey water and teasing her proboscis with a paperclip, I set her down and watched as she tasted her first drops of honey as a butterfly.

Once captive rearing is complete and the females finish laying their eggs, the butterflies are released to various South Sound Prairies, like the Glacial Heritage Preserve (photographed below). Here they will live the remainder of their lives, and we hope that they continue to mate and lay eggs in their native habitat to bolster populations directly.
