Biologist Mary Linders shows incarcerated technicians which areas of the prairie are currently occupied by reintroduced Taylor’s checkerspot butterflies.
In late spring, incarcerated technicians from Mission Creek Corrections Center for Women (MCCCW) had the opportunity to visit Scatter Creek Wildlife Area, a reintroduction site for federally-endangered Taylor’s checkerspot butterflies. These technicians work year-round to raise Taylor’s checkerspots in a greenhouse, but this is the first time they have been able to see the habitat where captive-reared butterflies and caterpillars have been released. Mary Linders and Josh Cook from Washington Department of Fish and Wildlife (WDFW) conducted a tour of the site, describing its history and ecology as they led us on a hike through the serene prairie.
Sickle-keeled lupine (Lupinis albicaulis) was in full bloom during our prairie tour, dappling the scenery with vibrant purple.
Our visit coincided with the end of the 5-week flight season, so adult butterfly sightings were limited. But technicians wasted no time in examining the Plantago lanceolata host plants and soon discovered Taylor’s checkerspot caterpillars! These hatchlings were just like the ones back in the lab at MCCCW and it was thrilling to find them living out in the wild. At the level of our toes, the habitat appeared to be teeming with young larvae. This particular site represents a major success for Mary Linders and WDFW who carefully reintroduced the species here over many years with the help of rearing programs at MCCCW and the Oregon Zoo.
As a Sustainability in Prisons Project (SPP) coordinator, I am always searching for ways to connect incarcerated technicians with the ecosystems they are helping to restore. Butterfly technicians know a lot about Salish lowland prairies from readings and discussion, but seeing the habitat with their own eyes provided a whole new level of insight. Hopefully this kind of trip can become a regular component of the program. I know it will help this group of technicians as they return to the butterfly lab at MCCCW and integrate their experience on the prairie into their work.
Such an opportunity would not have been possible without the officers and staff at MCCCW who supported this trip, and who play a vital role in hosting the Taylor’s checkerspot butterfly program throughout the year. A special thank you to Mary Linders, Josh Cook, and WDFW for being so generous with their time and facilitating this valuable learning experience for SPP participants.

It’s turtle trapping season for the Washington Department of Fish and Wildlife (WDFW). When we arrived onsite at the South Puget Sound Wildlife Area, Wildlife Biologist Emily Butler was already hard at work and chest-deep in one of the three ponds at the wildlife area that western pond turtles (WPT) call home. Emily and two dedicated volunteers were diligently placing traps in turtle habitat.

Along with trapping, WDFW also identifies turtle nests in the area. They establish a barrier to protect the site from predators. The barrier pictured below protects an active nest that currently houses WPT eggs. While the eggs will hatch in the fall, the turtles will not emerge until next spring, and it is crucial to protect them from predators until then.

As a recent addition to the SPP team, I was excited to see the Western pond turtle habitat firsthand. I am taking over Jessica Brown’s position as Conservation Coordinator with Cedar Creek Corrections Center (CCCC) and Larch Corrections Center (LCC), and working closely with WDFW to help western pond turtles fight off shell disease. Critically endangered in the state of Washington, WPT are a crucial native species that have recently fallen victim to shell disease, which deteriorates their shells and shortens the turtles’ lifespans.
In the next week WDFW will locate and identify any turtles that show signs of shell disease. The turtles that they trap will be evaluated at Progressive Animal Welfare Society (PAWS) where veterinarians will determine which individuals require treatment. Those turtles will then be transferred to Cedar Creek Corrections Center (CCCC) where SPP Biological Science Technicians will care for and monitor them through their recovery, then releasing the turtles next spring.

It was a pleasure to see the South Puget Sound Wildlife Area firsthand and gain insight from Emily. With two new Biological Science Technicians also joining our team, we all look forward to meeting our new patients soon and helping them along to a speedy recovery. Stay tuned for updates on our turtles in the fall!

The goal of an aquaponics system is to mimic nature by recycling nutrients from animal waste into plant tissue through microbial decomposition. The needs of fish, plants, and microbes must be balanced to keep the system functioning properly. The technicians at Stafford Creek Corrections Center are tasked with being sensitive to the needs of the system and work hard to maintain the balance among these symbiotic organisms. The technicians learn about plant and microbial ecology, water quality, and fish biology while also learning how to troubleshoot plumbing, heating systems, and pumps. When the system is working as it should, the technicians may be left with little maintenance to do. But when something goes wrong, such as a spike in ammonia or a failed pump, it is their job to figure out how to find the problem and fix it.
Danyl Herringshaw (left) and Joseph Oddo, current EVM technicians, are learning to maintain a system that often behaves in unexpected ways. This photo was taken just prior to loading mats for delivery…
This spring Danyl Herringshaw, an EVM technician since January, reflected on his experiences in the aquaponics facility:
“I think the most important thing I’ve learned since working at the EVM greenhouse at SCCC is the value of a mistake. The EVM greenhouse is a very delicate and fickle system. A small adjustment to the water flow can affect the entire system’s timing, for example. There have been countless examples of how I’ve learned and grown in my knowledge of this system from mine and others’ mistakes.
“This also puts into perspective how delicate a natural system is. Minor adjustments and maintenance seem to make this job slow, even boring sometimes. However, if an adjustment is too large or too small or a certain piece is overlooked during maintenance, it can have large ramifications. These adjustments and maintenance seem to happen effortlessly in nature.
“This is why natural habitats and ecosystems ought to be preserved when considering urban development. These systems are in place to keep us, and the wildlife that reside there, safe.”
In the EVM, we are doing our part to enhance natural ecosystems by growing native wetland plants in support of wetland habitat restoration for the threatened Oregon spotted frog. The plants are sown in soil and installed in mats once their roots and shoots are large enough. Then they continue growing in the mats until they achieve at least 50% cover. Mr. Herringshaw and Joseph Oddo, who has been working on the EVM project since March, have done an exceptional job sowing, tracking growth, and maintaining the health of the plants. We delivered another set of mats to Joint Base Lewis McChord in June.
…and this photo was taken after loading the mats! Each mat can weigh up to 100 pounds, even after they are allowed to drain and dry out for 24 hours.
Mr. Herringshaw and Mr. Oddo roll up the mats before loading them onto the truck. In the field, they will be rolled out and secured in place; the plants perk right back up.
This mat can’t wait for contact with soil! Imagine reed canarygrass trying to grow through these lush roots.
The EVM project is a learning laboratory for technicians and staff alike. Amanda Mintz, EVM Coordinator and Master of Environmental Studies graduate student at Evergreen, has been researching the effects of adding compost tea to the aquaponics water on plant nutrient content . Theoretically, the microbial community in the compost tea—a brew made by soaking bags of compost in aerated water—aids in plant nutrient uptake in several ways, such as helping decompose organic matter in the water, or stimulating plant hormones that promote growth and increase nutrient uptake. Mr. Herringshaw and former technician Matthew Fuller collected plant tissue samples for Amanda to take back to Evergreen’s laboratories for analysis, tracked plant growth and health data, and ensured that system parameters remained constant during the experiment.

Students observe a frame from the hive Mark brought in. This frame has wax on it and some cells were full of pollen.
Beekeeping has been growing in popularity throughout prisons in Washington State, with 12 facilities now housing hives! Clallam Bay Corrections Center (CBCC) is among them; the prison has 3 healthy hives tended by inmate and staff apprentice beekeepers certified by WA State Beekeepers Association. CBCC is located in Clallam Bay on the Olympic Peninsula adjacent to the Strait of Juan de Fuca.
Beekeeping instructor Mark Urnes shows students a bottom board from the hive he brought in as a demonstration tool.
The liaison holds a drawing of bee drone biology made by incarcerated students.
Earlier in the spring, CBCC hosted a day-long intensive seminar for a new group of incarcerated beekeepers. Beekeeping instructor Mark Urnes, the education lead for the North Olympic Peninsula Beekeepers’ Association, led the seminar and fielded many questions from the inmate beekeepers.They covered topics such as bee biology, pathogens, and colony collapse disorder. Students came prepared, so that they could get as much out of the intensive as possible; all had read scientific articles, bee journals, and reviewed their class notes from WA State Beekeepers Association apprenticeship curriculum. They brought with them drawings of bee biology and model hives that aided Mark’s descriptions and demonstrations.
The CBCC officer who sponsors the beekeeping program told me many stories about how beekeeping has had positive impacts on the lives of inmates and staff. The staff sponsor was proud to share that inmates who go through the program have a lasting positive effects from it. I was so happy to hear that the program is being so well received and having such a positive effect on the lives of those involved in it.
More images from the intensive follow.
Another sketch by incarcerated students shows a cross section of a hive showing the different stages of bee larvae within the hive cells.
This frame shows wax that is fresher, towards the side of the frame, compared to older wax in the middle of the frame.
Students listen as Mark answers questions.
Students had constructed a model hive out of paper (seen on the table) and Mark used it to aid the part of his presentation about the different parts of a hive and the purpose they serve.
Mark holds a picture of queen next to some worker bees. Here he was talking about the importance of queen health to the hive as a whole.

In April, I was fortunate to spend days and days immersed in the topic of astrobiology. What is astrobiology? It is the study of how stars and planets form, how that relates to life here on Earth, and the search for life elsewhere in the Universe. Alongside hundreds of incarcerated students and dozens of corrections staff in both Washington and Ohio, I got to learn about what is known, what is still unknown, and ponder immense questions. I had stars in my eyes, for sure!
Here I will share details from the Washington State programs; I will share Ohio’s in part 2. In Washington, Daniella was joined by Dr Drew Gorman-Lewis, Associate Professor in the Earth and Space Sciences at University of Washington. Our small team visited five prisons in four days, reaching 450 incarcerated students and 52 corrections staff. At each venue, Drew and Daniella told us a three-part story.
Part One: Creation
Daniella introduced us to the life cycle of stars—who knew that stars had life cycles!—and how their birth, maturity, and death creates and distributes most of the elements that makes up the Universe as we know it. She told us: Every atom in our bodies, the water we drink, the food we eat, our buildings, our roads, the things we buy and make, all were built in the heart of a star. It’s a dizzying concept, one that connects everyone and everything.
She outlined how these elements may have come together in the nutrient and energy rich environments of hydrothermal vents—hot water vents at the ocean floor—to create the first microbes, the first life on Earth.
Part Two: Adaptation
Part two came from Drew. He told us about his research with microbes, single-celled organisms, that live in extreme environments on earth. His personal and professional favorites live in near-boiling pools of acid—really! He emphasized that there are microbes living and thriving in nearly every environment on Earth. Those inhabitants also influence their environments; their life processes take up, transform, and leave behind new elements and structures. The microbes can quickly adapt to take advantage of new conditions, and so back and forth, life and the Earth interact and influence each other. His research investigates how much energy microbes use to live in extreme environments, and in this way sheds a bit of light on where and how we might find microbes beyond our Earth.
Part Three: Exploration
Daniella’s part three dove into this search for life, focusing on the most promising worlds within our solar system. I was amazed to learn that there are some excellent contenders! I was particularly taken by moons of Jupiter and Saturn, Europa and Enceladus, that have global oceans: hidden beneath icy crusts, their worlds are covered with liquid water. On Enceladus, there is also evidence of geothermal vents. Given that one of the theories for the origin of life places it in Earth vents, this news of similar environments on a moon of Saturn gave me the chills (the good kind).
At every venue, the students dazzled us with ideas and questions. I think that’s the best part for me—hearing how others are making sense of the concepts, the collective insights and exploration. I learned as much from them as from the scientists…as usual!

On April 23rd, Washington Corrections Center (WCC) hosted their first workshop of SPP’s Environmental Engagement Workshop Series. This is our second try expanding the program to Shelton, but we expect it to stick this time! Staff supporting the program at WCC and Evergreen know better how to make it work, and everybody is on board with making it so.

We were lucky to re-launch the series with a veteran presenter: Max Calloway studies kelp in the Salish Sea, and he is a compelling and accessible expert. WCC Superintendent Dan White said, “The presenter was EXCELLENT! I learned some very interesting things today.”
The event was well-attended, with 27 incarcerated students and 14 corrections staff giving their attention to the topic. All present were fully engaged and the topic questions and discussions were lively and insightful.
We are grateful for Jeffry Sanders, Dean Mason, Jenn Bullard, and the Superintendent—they are great folks to work with. We know that their enthusiasm and dedication to programming will make this program an ongoing success.
Correction Specialist Jeff Sanders has only recently taken on the role of overseeing sustainability programs for the institution, and he is off to a promising start. He left the workshop with, “Thanks for all that came, and we look forward to next months’ workshop!”

Each year, the Sustainability in Prisons Project’s (SPP) Taylor’s Checkerspot Butterfly Program rears thousands of endangered caterpillars for reintroduction to the wild. Incarcerated technicians at Mission Creek Corrections Center for Women (MCCCW) shepherd these rare butterflies through each of their four life stages—eggs, larvae, pupae, and adults. The transition from winter to spring is an exciting time for the program because that’s when all the action happens: the larvae wake up and begin to eat, followed shortly by pupation, adult emergence, and captive breeding.
Taylor’s checkerspots are adult butterflies for only about 5 weeks during the spring, so things happen fast; now that we’re nearing the end of “flight” season, it all feels like a white and orange blur! And yet, a lot has happened in the past few months. Two new butterfly technicians joined our team, ~2,800 post-diapause larvae were sent to Joint Base Lewis-McChord for release, 225 adult butterflies eclosed in the lab, and technicians hosted site visits for some of our most valued partners (including one very special guest). To top it all off, the MCCCW butterfly crew celebrated their most productive breeding season to date!
(Left to right) Technician Susan Christopher, WDFW Biologist Mary Linders, and Technicians Nichole Alexander, and Alexis Coleman work together to decide which caterpillars should be released this year and which ones should remain at MCCCW for captive breeding.
Technician Nichole Alexander labels individual deli cups full of caterpillars that have just been woken up from winter diapause. Over 3,000 hungry caterpillars now line these shelves waiting to be released!
WDFW Biologist Mary Linders directs volunteers at a Taylor’s checkerspot release site. We transport caterpillars from the prison to the field and very carefully introduce them to their new environment.
A volunteer transplants Taylor’s checkerspot caterpillars to Plantago lanceolata host plants. It is early spring, so much of the prairie vegetation has yet to flower.
A few caterpillars remain in the MCCCW lab where they will mature to produce some of the program’s next batch of eggs. Here, a few caterpillars get fat and happy as they prepare for pupation. A group of fifteen caterpillars can eat up to eight Plantago leaves per day! Technicians have to feed them constantly to keep up with their appetites.
Once they have reached the appropriate size, caterpillars crawl to the top of their mesh enclosure and hang in a ‘J’ shape before transforming into a chrysalis. Pupation is such a strange and beautiful process to behold, and MCCCW technicians get to watch it happen right before their eyes.
Midway through the season, Carolina Landa (far right) and Dennis Buckingham (second from the left) paid a special visit to the butterfly program. Dennis was the first SPP coordinator and Carolina was one of the original incarcerated technicians, and the part she played in shaping the program is legendary. Carolina returned to MCCCW and share valuable words of encouragement with the current technicians. It was a great opportunity to present Alexis Coleman, Nichole Alexander, and Susan Christopher with their Butterfly Rearing and Research Specialist certificates.
About three weeks after pupation, butterflies begin to emerge from their chrysalises. This is a rewarding moment for the butterfly technicians, but it also means more work! Each butterfly needs to be fed honey from a Q-tip, weighed on a scale, photographed, identified as male or female, and placed in the appropriate enclosure.
Technicians pair male and female checkerspots based on their genetic lineage. Males and females are introduced to each other in these mesh tents. The butterflies were very cooperative this year, wasting no time in consummating the match.
Mated pairs are removed from the breeding tents. Technicians then place the female butterflies on Plantago plant for egg-laying. The male gets to go hang out with his buddies until they are released into the field.
A mated female lays eggs near the base of Plantago lanceolata. In the wild, this is a great place to keep the eggs safe from harm, but in the lab, eggs laid this way pose a challenge for technicians. They will have to use a tiny paintbrush to remove these fragile eggs and transfer them to a 5.5oz cup where they will eventually hatch.

Karen and Tom from USFWS oversee Taylor’s checkerspot recovery on a regional level; they took time out of their busy schedules to visit the MCCCW captive rearing program and see firsthand the work that incarcerated technicians are doing to support endangered species conservation.
Technician Alexis Coleman shares her observations about Taylor’s checkerspot egg-laying behavior with Tom McDowell and Karen Reagan from USFWS.
This year was the most productive breeding season to date for MCCCW: our captive-bred butterflies laid over 7,000 eggs! This is great news for the program and for species recovery in the field, and the technicians at MCCCW should be proud. Their contributions are vital to restoring Taylor’s checkerspot populations in Washington State.

I recently visited Olympic Corrections Center (OCC) on the Olympic Peninsula near Forks, Washington. OCC is a “camp” for incarcerated individuals with 4 years or less remaining in their sentence. Inmates at OCC learn trades and gain valuable experiences for when they release. Among many options available to them is working for the Department of Natural Resources (DNR) as response teams for flooding, forest fires, and other work within national parks. OCC has an impressive garden setup where they grow plants and seedlings; they use these areas as labs for learning horticultural science and plant biology (a Peninsula College program). They also have excellent composting and wood shop programs.
It was a privilege to see their programming. Here are a few snapshots of their great work.
The greenhouse at OCC has seedlings, produce, flowers, and tropical plants. They grew dozens of flower baskets for Mother’s Day, for both inmates and staff to give to their mothers and wives.
Greenhouse technicians, like Wade pictured here, care for the plants while learning how to sow and grow a prosperous garden.
Look how big this succulent is! Greenhouse technicians have been caring for this guy for about 10 years.
Mark Case is another greenhouse technician. He hopes to have his own garden when he releases where he can put to use all of the knowledge he’s gained from working and learning in the gardens at OCC.
This pineapple isn’t ripe yet, but it sure is cute! When the pineapples are ready to eat, the technicians harvest and eat them.
Food, garden, and organic waste is composted on site at OCC. They have a large warehouse specifically designed for composting organic waste. The facility trains technicians who can then use this knowledge and skill base when they get out of prison.
OCC produced about 23 tons of compost last year alone! The product is used to amend the soil throughout the prison grounds.
The wood shop at OCC uses donated or reclaimed wood to make wood toy trucks, tractors, and cars. Each intricately detailed toy goes to charity for children.
Here are some more completed projects awaiting to be painted with sealant. Such nice work!

We started in the EVM greenhouse, where we discussed past mat production and future production potential. Last year, we produced and installed more than 100 mats at south Puget Sound restoration sites! The technicians described how the system works, and we all stopped to marvel at the fish—about 130 koi provide most of the nutrients absorbed by the wetland mats.
Not just beautiful, koi are hardy fish adaptable to unexpected changes in water chemistry; this makes them perfect for an aquaponics system. Photo by Ricky Osborne.
Technician Brian Bedilion, who has worked for the EVM program since its inception in 2016, explained how working for SPP has impacted his self-confidence and goals for his future. His creativity and ability to troubleshoot on-the-fly have been integral to the success of the EVM program. Brian went home on April 13; we wish him the best, and hope to see him in the field!

After touring the EVM greenhouse, we went inside the fence to see the prairie conservation nursery, gardens, and other sustainability programs hosted by Stafford Creek. Every living area has dedicated garden space for its residents. A larger space outside the education building is intended for men serving life sentences, and is known as the Lifer Garden. The Lifer Garden and one other at Stafford Creek grow produce for local food banks. Last year, incarcerated individuals at the prison grew and donated almost 12,000 pounds of produce!

The tour ended with visits to the shop areas, where partners saw bicycle and wheelchair repair. Like all the other programs we saw at Stafford Creek, these programs bring together partners to create something of value for the benefit of our environment and our communities.
Kinnikinnick (Arctostaphylos uva-ursi) is tough to grow from seeds. Kinnikinnick seeds have compound dormancy: before germination can occur, the seed coats must be made permeable to water (breaking physical dormancy), and must undergo a number of internal biological processes (breaking physiological dormancy). Though there are known methods to overcome the double dormancy, the results are highly variable and inconsistent. Most commercial nurseries grow the plant from softwood cuttings, but these lack the genetic diversity of seed-grown stock.
Bombus vosnesenskii collects nectar from kinnikinnick flowers.
SPP’s conservation nursery has taken on the challenge of seed-grown kinnikinnick, because of the benefits it brings to pollinators at restoration sites on Joint Base Lewis-McChord. Delightfully bright yellow-faced bumblebees (Bombus vosnesenskii) and fuzzy black-tailed bumblebees (Bombus melanopygus) perform acrobatics to collect nectar from its flowers. Both of these hardy insects fly out at any early promise of spring. These are just two of the many pollinators that gain sustenance from this important plant.
Kinnikinnick provides both an early bloom time and an extended bloom period spanning a couple of months. This blooming phenology (cycle) allows pollinating insects to build up their populations early in the season. These fortified populations carry over into the spring and summer, providing increased pollination services to many prairie plants. Susan Waters from Center for Natural Lands Management is surveying Salish lowland prairies’ pollinators, and has developed detailed graphics of pollinator networks demonstrating the importance of bumblebees as pollinators for numerous plant species used in restoration.
Conservation nursery technicians coax the December fire needed for one of the pre-treatment trials.
This year, SPP program team designed a study of kinnikinnick germination at Stafford Creek Corrections Center (SCCC). The nursery technicians drew from what they had learned about the scientific method from a program workshop. SPP staff and the technicians aim to find out the most consistent pre-treatment to overcome the physical dormancy, plus the best length of time in cold-moist conditions to reduce physiological dormancy. Together we developed a methodology to test means to overcome the dormancy of kinnikinnick seeds and promote germination. In December, SPP-Evergreen and SCCC staff gathered with the technicians to perform the range of pre-treatments.
Nursery Specialist Ed Baldwin (right) pokes fun at the chances that they’ll need the fire extinguisher.
We performed three pre-treatments and a control. First was to dip the seeds in 80°C water for 2 minutes; second we immersed seeds for 24 hours in an acid bath of distilled white vinegar (the most acidic thing we could use in a corrections setting). The third treatment was a very controlled burn: after safety precautions were in place, seed was laid out on a bed of sand and covered with 2 cm of sand; 12 inches of dried grass clippings were piled and lit aflame. Since December in Aberdeen, WA is not particularly dry, fire-prone time of year, significant effort was put into keeping the flame burning.
The seed from each treatment was sown separately in the nursery’s standard cone-tainers, and will spend the winter in cold-wet stratification. Only warming weather of mid-spring can bring forth answers to our germination trials, but already the technicians, staff, and the bumble bees are betting on the outcome.
Kinnikinnick seeds look like they survived the controlled burn just fine.
