The Oregon spotted frogs (OSF) at Cedar Creek Corrections Center (CCCC) are the subjects of a growth comparison study between two separate OSF populations: Black River and Conboy Lake.  Inmates at CCCC are raising the two populations side-by-side in separate tanks, keeping all rearing conditions identical, in order to compare growth rates.  Measurements have been taken throughout the rearing season and will be taken again just prior to release in October at Joint Base Lewis McChord.  The OSF population at Conboy Lake is the only source population that successfully cohabitates with bullfrogs, a primary predator of OSF.  The hypothesis is that OSFs from Conboy Lake are bigger in size, and as a result of that, are faster in their response to predation.  This study will help determine whether or not captive rearing efforts should focus primarily on the Conboy Lake population.

As part of the comparison study, the OSFs predator response instincts were also tested.  Twenty frogs from each population were isolated for a short period of time in a stimulus free environment.  One by one, they were placed in a large plastic tub filled with just enough water to cover their bodies.  Once they relaxed enough to come to the surface and rest with their eyes out of the water, a plastic ball–tethered to stop before impact–was dropped from above, simulating a predator in the wild.  Each individual test is filmed to record the amount of time it takes each frog to react to the “predator”, and also to record response distance in its effort to escape.  The film is reviewed and data logged at the Oregon Zoo.  The data will allow for a parallel test between the Black River and Conboy Lake populations, and also a comparison between OSF rearing institutions, CCCC and Oregon Zoo.

The experiment took place at CCCC under the supervision and guidance of Senior Research Scientist Dr. Marc Hayes and Kyle Tidwell from the Oregon Zoo.  SPP interns Dennis Aubrey and Sarah Weber, and CCCC OSF inmates assisted with noting sex, coloration and tag number as well as taking the measurements and weight of each individual frog in order to identify any size or mass related variation in response. The inmate’s contribution to the predator response experiment and the side by side growth comparison study is integral to development of the OSF captive rearing program.  The rearing season continues at CCCC with inmates raising fat, healthy frogs getting closer to their release date.

Congratulations to SPP Director Dr. Carri LeRoy, and SPP Research Associate Carl Elliot on their recent publications in the Northwest Science Journal!

Together with Dr. Dylan Fischer of Evergreen State College they co-authored Germination of Three Native Lupinus Species in Response to Temperature.  Experiments to determine the effects of pre-germination treatment and germination temperature conditions on the proportional germination of three species of Lupinus are discussed.  The results could lead to better understanding of germination requirements of native species, an important component of restoration in south Puget Lowland prairies.

Dr. LeRoy was also co-author of a paper on Responses of Prairie Vegetation to Fire, Herbicide, and Invasive Species Legacy.  Native and exotic plant community diversity and composition were measured across areas that differed in burning history and grass-specific herbicide application in an effort to evaluate prairie plant community variation in a matrix of restoration treatments in the south Puget Lowland prairies.

Both papers are available for download via Open Access on the Northwest Science BioOne page:

Celebration and Transition

By SPP Project Manager Kelli Bush

The Sustainable Prisons Project (SPP) recently celebrated another year with our many wonderful partners.  The event, held on a cool summer evening at the Olympia Farmer’s Market, featured a wide range of guest speakers representing various aspects of the Sustainable Prisons Project.  Speakers from Department of Corrections, Joint Base Lewis McChord, The Evergreen State College (TESC), Center for Natural Land Management, Washington Department of Fish and Wildlife, and a prison volunteer each spoke about the significance of SPP from their perspective.

 

The event was also an opportunity to honor out-going Co-Director and Co-Founder of the SPP, Dr. Nalini Nadkarni.  Nalini has accepted a position at University of Utah as the Director of the Center for Science and Math Education.  She will remain involved with SPP as Senior Advisor.  Nalini is also continuing work to share SPP with other states, including at her new location in Utah.

 

We also welcomed new SPP Co-Director Dr. Carri LeRoy.  Carri began working with the SPP team in April and she officially began her new role as SPP Co-Director July 1st.  She is a stream ecologist and a member of the Masters of Environmental Studies faculty at Evergreen.  Carri is an excellent addition to the team and we look forward to continuing the Project with her leadership.

 

After a year filled with declining budgets we are extremely grateful to our partners, students, TESC staff, foundations, and grant funding sources that helped keep this project going.  We are excited to see what the next year brings!

Blooming Inside the Walls

By Graduate Research Associate Carl Elliott from Stafford Creek Corrections Center

Surrounded by acres of Douglas-fir forest and behind razor wire security fences, a garden tended by the offenders at Stafford Creek Corrections Center is flourishing. Their efforts to cultivate food and flowers has altered the landscape and nourished the spirit of those involved.  These men asked me to provide a documentation of the garden for their families on the outside.  I thought that this service alone was worth providing, but I also feel others outside the prison fence should have the opportunity to see and hear about the garden.

The spring weather on the coast of Washington this year was unusually cool and cool nights persist through July. Night temperatures have rarely stayed above 50° F. The cool weather caused heat loving plants like tomatoes, peppers, and squash to languish.  However, crops such as broccoli, cabbage, peas, and carrots have exploded with growth. The offenders are gathering buckets full of carrots and peas to share with the prison kitchen.

All of the flower gardens were designed by the offenders. They paid special attention to creating habitat for insect pollinators. The plant families they cultivated in the pollinator garden were from the pink or catchfly family, the sunflower family, the pea family, and the mallow family. These plants provide nectar, pollen, and insect prey for beneficial insects.  This is important because the garden is surrounded by concrete which provides poor pollinator habitat.

The other flower gardens include a cutting garden and a native prairie garden. The flowers from the cutting garden are used to beautify the visitor room in the summer. This allows friends and family to see the fruits of the men’s labors and make for a beautiful reception for visitors. The native prairie plant garden overflows with species from the conservation nursery. By seeing the plants they are cultivating for restoration, the men can begin to learn plant families and plant community associations found on the prairies.

The whole garden sits amidst a sea of concrete. Originally, it was a turf covered turn-around for delivery trucks.  Staff grounds keeper, Jon Rydman, took the initiative to open up the space for the men to garden there two years ago.  After a great amount of initial effort to cut the sod, lay the irrigation, and form the beds, the garden was started.  Soil fertility has been improved by compost generated from prison kitchen waste. This unique in-vessel composting system is a pilot project coordinated by plant manager, Chris Idso.  Creating a flourishing garden in a Correction Center requires cooperation and coordination among staff.  The garden produces more than vegetables and flowers; it is also a place for education and change.

SPP Launches New Conservation Program at Mission Creek Corrections Center for Women

By Graduate Research Associate Dennis Aubrey

The Sustainable Prisons Project (SPP) and the Mission Creek Corrections Center for Women (MCCCW) are preparing to launch a brand new conservation program.  In addition to prairie plants and Oregon spotted frogs, we will be partnering on a new captive rearing program to raise Taylor’s checkerspot butterflies (Euphydryas editha taylori) for release on South Sound prairies.  The Taylor’s checkerspot is listed as a state-endangered species in Washington and is a candidate for listing under the federal Endangered Species Act.  These butterflies once flourished on glacial outwash prairies, low elevation grassy balds and coastal grassland sites from southern British Columbia to central Oregon, but in recent decades habitat loss and degradation have reduced it to a few small, isolated populations.

Staff at MCCCW are currently hard at work constructing a custom greenhouse at the prison which will house the program, The UV light transmission of the glass structure will provide the checkerspots with ideal growing conditions, and its interior partition will create two separate climate controlled rooms.  The building is expected to be complete by the end of the month, and the first release of larva onto South Sound prairies will occur in April 2012.  Currently the Oregon Zoo is the only facility rearing Taylor’s checkerspots.  The new structure at the prison will provide a second rearing program to assist with butterfly recovery efforts.   The project is generously funded by the Army Compatible Use Buffer (ACUB) program, US Fish and Wildlife Service, and The Nature Conservancy.  Other collaborating partners include Washington Department of Fish and Wildlife, Washington Department of Corrections, the Evergreen State College, the Oregon Zoo, and Joint Base Lewis McChord.  Even though the new rearing facility is not yet complete, SPP graduate student intern Dennis Aubrey has been busy preparing for the new program.  Dennis is receiving training from staff at the Oregon Zoo as they raise checkerspots, as well as assisting with field activities. He recently helped release 1036 prediapause checkerspot larva at the Scatter Creek Prairie restoration plots.  Along with staff at MCCCW, he also helped conduct interviews and hire inmates for the rearing technician position.  Dennis will continue to play an active role in training incarcerated women to become butterfly rearing technicians.

Our partners at MCCCW have been enthusiastic participants in all phases of the planning and implementation of this project.  All involved are optimistic that this is the beginning of a successful long-term undertaking to recover endangered butterflies and bring science education to incarcerated women.  This program promises to be an integral part of a growing culture of sustainability and conservation at the facility.

Arboriculture Workshop at Cedar Creek Correction Center

Noe Cardenas- Certified Arborist- City of Seattle teaching about arboriculture

The SPP recently held a full day workshop on arboriculture at Cedar Creek Correction Center.  The workshop was a great success with nearly 40 inmates (maximum allowed) and approximately 12 staff in attendance.   Arboriculture is defined by the International Society of Arboriculture (ISA) as the art and science of planting, caring for, and maintaining individual trees.  Arborists are knowledgeable about tree health and are trained and equipped to provide proper care.  Inmates participating in the workshop already have an interest and some experience working with trees.  They are all members of Washington Department of Natural Resources (WDNR) forestry crews.  Inmates on these crews work full-time planting trees, controlling weeds, fighting forest fires, and assisting with native plant restoration projects.

The workshop covered a wide range of tree-related topics including: forest ecology, an introduction to arboriculture, tree biology, tree career options, pruning, and a tree climbing demonstration.  Seven different volunteer presenters took time away from their busy schedules to share their passion for trees with the inmates.  The goal of the workshop was to introduce inmates to arboriculture and other tree-related careers.  We hope to inspire inmates to consider becoming ISA Certified Arborists.  ISA certification is quickly becoming a minimum requirement in many tree care companies.  Certified Arborists are able to demonstrate a standard of knowledge and dedication to tree care; which can provide an advantage in today’s job market. The ISA has generously donated 50 certification exam study guides and featured the SPP in the April edition of their publication Arborist News.

If resources allow, the SPP will work with our partners at WDNR and Washington Department of Corrections (WDOC), to build a certification training program in the near future.  The training program would bring together volunteer instructors to help qualified inmates prepare for the arborist certification exam.  An education and certification program at Cedar Creek Correction Center could provide multiple benefits including:

  • employment opportunities at a decent wage for inmates post-release;
  • green-collar job training which builds a new work force to care for our urban forests;
  • involvement with the ISA, an organization that encourages on-going educational and professional development;
  • the program may serve as a model for other prisons and other states;
  • with increased employment opportunities and education, inmates may be less likely to re-offend when they are released.

Many thanks to the volunteer presenters, students, and agency partners that helped make the workshop a success.  Please stay tuned as we carefully explore options for expanding this education opportunity.

Smoke Water

by

in Ecological Research Education Science

Posted by Graduate Research Associate Carl Elliott

In a plant nursery that focuses on native plants and restoration, expectations are a bit different than at a traditional commercial nursery. Commercial nursery production has focused on those plants that make a good economic return for the grower. All managers of commercial nurseries know that if you have a rapid and efficient turn-over of plant material through the year, you generate a greater income per square foot. There is an industrial infrastructure and research to support the industry in this process.  For restoration nurseries interested in basic germination protocols or more complex issues of genetic integrity or in-breeding depression, there is not such a well-developed research infrastructure, and a great many questions remain to be answered.

At the conservation nursery at Stafford Creek Corrections Center, we have generated a number of basic scientific questions regarding the germination ecology of the prairie species we cultivate. One of the most engaging is the seeds response to prairie fires. Fires have been an integral tool to maintain prairies in the Pacific Northwest for at least 8,000 years. The fires in this ecosystem are not natural; they were used by First Peoples to maintain the extant and health of the prairies that are surrounded by evergreen woodlands. The seeds of over 250 species of plants have been shown to significantly increase in response to the smoke generated by fires. This is particularly true for species from fymbos matorral, chaparral and grassland ecosystems. So, our project developed a question to determine whether the smoke from fires could increase the germination rates of some of the more difficult to germinate plants.  Rather than apply smoke (and therefore fire) to the seeds themselves we applied smoke infused water as a treatment to seeds.

I took on the scientific design and execution of the seed germination experiments as part of my graduate thesis at The Evergreen State College. However, the experiment is a fully collaborative endeavor. The Nature Conservancy collected and curated the seed from their Shotwell’s Landing nursery. The offenders at Stafford Creek cleaned the seed, counted out replicates and participated in the germination experiments involving six of the species. The experiment involved measuring the germination rate of the six species. The seeds were divided into three treatment groups: two different levels of smoke water and a plain water control. The offenders applied the treatments to 10 replicates of each and the monitoring for germination went for 35 days.

Inmates at Stafford Creek Corrections Center count seed.

To prepare for the experiments, the offenders participated in workshops designed to facilitate discussions about the scientific methods used to come to robust conclusions. It was not the first time that offenders were exposed to a scientific reasoning process. Many have previous educational experience or have attended enough lectures organized by the Sustainable Prisons Project to be confident about offering their opinions to a discussion on scientific methods. At this point the experiments are nearly complete on most of the species and we can compile and analyze the results. My goal is to be able to go over some of the statistical methods used and get the offenders input on how the results we get can be used in the nursery to increase our propagation success. Look forward to the results in future posts.

A New Season

by

By Graduate Research Associate Carl Elliot

The nursery sowing season at Stafford Creek Correction Center (SCCC) opened amidst mud and construction.  Excessive rainfall throughout the spring led to great volumes of mud around the nursery, just as we completed the moving of the greenhouses from one area of the prison to another. I know that sounds redundant – excessive rainfall in Aberdeen, Washington – but it was truly more rain that usual.  April 2011 was one of the top five coldest April’s on record and one of the top ten years for precipitation. The State Climatologist’s report has some interesting facts about our anomalous weather. The rainfall combined with construction made for a muddy mess, but the building was well organized by the construction supervisors and crew at SCCC. Though they had to apply more foundation rock into the muddy morass than was budgeted, the green house and two hoop houses were up and running by the middle of April.

The greenhouse is beginning to get full as offenders sow seeds

Sowing began with some new species this year and some of the target species from previous years. Lomatium triternatum, the nine leaved biscuit-root, was a new species to the nursery and the early sowing in April should make for well rooted plants by October. Castilleja hispida (harsh Indian paintbrush) and Viola adunca (blue violet) are two species vital to the pollination ecology of the Salish Sea (Western Washington) prairies. We will probably be sowing these two species every year at the nursery for as long as it is in existence; the need for them for pollinator restoration is inexhaustible. With these two species, our goal this year is to perform trials, testing the germination rate in response to varying lengths of stratification. Stratification is the process of subjecting seeds to cold and/or moisture to replicate environmental conditions required to break seed dormancy.  Through trials, we hope to determine the appropriate amount of stratification time these seeds require to generate a high germination and seedling success rate.  To date, our experiences germinating these species in the nursery has not corresponded with what is indicated in the published literature. 

Research Associate Carl Elliot teaches about the ecology of the plants offenders are learning to sow.

We’ve also had several new members join the crew.  These new offenders have benefited from the training and experience of those that have returned from last season. The training video that was produced last year is very helpful in providing and introduction to nursery techniques.  We’ve partnered each new member with a mentor to learn about nursery production.  By learning each aspect of the nursery from soil making to record keeping, the offenders develop a greater range of skills to use when they re-enter society.

SPP Research Associates Present Their Theses

By Graduate Research Associate Alicia LeDuc

Two of SPP’s former Graduate Research Associates have completed theses for the Master of Environmental Studies program at The Evergreen State College.  Liesl Plomski and Sarah Clarke selected topics related to the Sustainable Prisons Project. Both women have been integral parts of SPP since its early inception, working closely with inmates and DOC staff in two of Washington’s prisons.

Liesl Plomski presented her thesis regarding best practices in the rearing of endangered Oregon Spotted Frogs, drawing on her experience working with inmates at the Cedar Creek Corrections Center in Little Rock, Washington.  Plomski said she enjoyed working with inmates on the conservation efforts and that, “experiencing the importance of tuning people into a passion for positive development has definitely affected my subsequent career choice since finishing at Evergreen.” Plomski now lives in Portland, Oregon where she works mentoring at-risk youth.

Sarah Clarke completed her thesis on the impact of horticulture therapy and how working with living things affects the knowledge, behavior, and attitudes of inmates participating in the Sustainable Prisons Project.  Her work included data from four institutions working with  SPP.  Reflecting on her experience with inmates at the Washington Corrections Center for Women in Gig Harbor, Washington, Clarke said, “working with SPP has profoundly changed my life.  It has been rewarding on a personal level to work with inmates and see how interacting with nature benefits them.” One of SPP’s first Graduate Research Associates, Clarke said it was exciting to be part of a ground-breaking project from the very start. “It was a meaningful job that will be hard to replace,” she said.  Clarke now works at the Evergreen State College as a youth educator in the childcare center.

Both former SPP staff attested to the personal growth and professional rewards of working with the SPP.  Referring to her work lecture coordination and project evaluation efforts, Clarke said SPP enhanced her ability to work independently, manage time efficiently, work with a wide range of people, and change roles quickly. “I gained confidence to make judgments and take actions in new territory,” she said. Plomski agreed with Clarke’s observations, adding that working with SPP also improved her communication and analytical skills while working in a variety of different settings.

Most of all, the former Research Associates attested to the immense personal reward and satisfaction they felt when working with SPP.  Plomski said, “You come home at the end of the day and honestly feel like you’ve made society a little better, you actually did something.” For Clarke, it was, “really rewarding to witness the human healing that comes from working with nature.”  Both Plomski and Clarke have made contributions that continue to leave a lasting impact on the inmates, DOC staff, and community members they worked with over the course of their tenure with the Sustainable Prisons Project.

Oregon Spotted Frog Egg Masses Discovered Near Release Site!

By Undergraduate Research Associate Dennis Aubrey

Oregon Spotted Frog egg masses at Joint Base Lewis-McChord indicate SPP's conservation efforts are working.

The most exciting news imaginable came in last week!  Biologist Jim Lynch and his team discovered the first Oregon spotted frog egg masses on Joint Base Lewis-McChord since captive rearing programs were established.

This indicates the overall success of reintroduction efforts so far.  Some of the frogs released have survived to reach sexual maturity, and furthermore have done so in large enough numbers to find one another and successfully reproduce.

The news was greeted with great relief and elation on the part of all four rearing institutions.  Until now we have been diligently working with our partners at the other captive rearing facilities, not knowing what impact the work was having on the local Oregon Spotted Frog population. Egg mass surveys will continue in the next few weeks to assess the extent of breeding success.

SPP research associate Dennis Aubrey releases frogs he raised with inmates at Cedar Creek Corrections Center.

In related news, the frogs which were held over the winter at the OSF facility at Cedar Creek Corrections Center were successfully released on Ft. Lewis. We now know that they joined a waiting population of siblings! Interestingly, it was striking to note the behavioral differences in the frogs at the actual moment of release. When the lids were pulled back on the travel tubs containing the frogs, some immediately scrambled into the water and dove down to instantly bury themselves in the mud, while others were clearly reluctant to depart and had to be hand-coaxed into the cold water. The last few sat on the outstretched hands of SPP research associates Dennis Aubrey and Sarah Weber for several minutes and ultimately had to be dunked and let go before they would swim away.
