In mid-October, SPP delivered our third batch of Emergent pre-Vegetated Mats (EVM) to wetlands at West Rocky Prairie, Joint Base Lewis McChord (JBLM) and Mima Creek Preserve. At these sites, the Center for Natural Lands Management (CNLM) is conducting an experiment using the mats as part of a reed canarygrass suppression strategy. Replacing the reed canarygrass with wetland plants will help restore habitat for the threatened Oregon spotted frog. This project is supported with funding and resources by the Washington Department of Fish and Wildlife, United States Fish and Wildlife Service, CNLM, and JBLM.

Prior to delivery, we rolled up the mats and let them drain for 24 hours. Even with reduced water, each mat weighs about 60 pounds when it is delivered—healthy roots and shoots are heavy!

Each mat contains a combination of native wetland plants: spreading rush (Juncus supiniformis), tall mannagrass (Glyceria elata), and creeping spike-rush (Eleocharis palustris). The mats were produced in Stafford Creek Corrections Center’s aquaponics greenhouse by a team of corrections staff, incarcerated technicians, and SPP-Evergreen staff.

Staff and volunteers from CNLM and JBLM lay three, 1-meter by 3-meter mats side by side and anchor them with biodegradable stakes.

At each site, the mats are arranged in squares, three meters on each side. Staff and volunteers from JBLM and CNLM prepared the sites using a variety of combinations of herbicide, mowing, and solarization to remove the reed canarygrass; on the day of mat installation, they removed dead grass and root material with weed cutters making it easier for the plants in the mats to make contact with soil and establish themselves quickly. Teams will revisit each square to determine which of the various reed canarygrass treatments best allowed the native wetland species to take hold.

At the site shown here, reed canarygrass was treated only by mowing; in the background, you can see its pre-mowing height of up to six feet tall. Sarah Hamman deploys a water depth gauge–believe it or not, this is a wetland!

Will the coconut coir mats prevent reed canarygrass from growing back? Will the native plants grow quickly enough to establish healthy populations, competing for space with the reed canarygrass? Stay tuned to find out!

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!

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!

French Film Crew Visits SPP!

Filming Oregon spotted frog search

A French documentary crew recently visited Western Washington to film a new episode for their National Geographic series “Guardians of Nature”.  The episode will include segments featuring the Sustainable Prisons Project (SPP) Oregon Spotted Frog Program and riparian forest research conducted by SPP Co-Director Dr. Carri LeRoy.

 

The film crew spent an entire day with the SPP Oregon Spotted Frog Program team.  Filming began at Cedar Creek Correction Center in the morning.  SPP staff and inmates walked the crew through the daily tasks associated with caring for the endangered frogs.  Prison Superintendent Doug Cole shared his thoughts on the benefits of the program from a prison perspective.

SPP Co-Director Carri LeRoy and Project Manager Kelli Bush at West Rocky Prairie

The afternoon was spent at West Rocky Prairie in the greater Olympia area.  West Rocky Prairie is home to a wild population of Oregon spotted frogs.  Dr. Marc Hayes, senior biologist at the Washington Department of Fish and Wildlife, led the group to a wetland location where he netted two juveniles and one adult frog to show the film crew.  He explained how factors such as habitat loss and bull frog predation have led to the decline of the species and discussed current efforts to recover the native population.  The day concluded with summary discussion of the Sustainable Prisons Project and the many benefits of including incarcerated individuals as partners in conservation and sustainability work.

The film crew also spent a day with Dr. Carri LeRoy filming riparian and stream science research on the Hoh River. The Hoh River is a braided gravel stream channel fed from the glaciers of the Olympic Mountains and flowing through densely vegetated temperate rainforest and cottonwood (Populus trichocarpa) gallery forests. Dr. LeRoy’s research on how the genetics of cottonwood trees can influence both other members of the ecological community associated with the trees and the ecosystem-level processes of riparian forests was the focus of the interview. Although it might seem impossible for something as small as a gene to have an effect on a whole ecosystem, there are many examples of the strong organizing power of genes. Genes can influence the insects that live in tree canopies, bird predation and nest building, deer browsing, soil organisms, nutrient cycling, carbon flux, water use and even adjacent stream communities and ecosystem processes. Dr. LeRoy’s “Genes-to-ecosystems” research involves examining the interactions between tree genes, forests and streams through leaf litter fall.

With the dynamic backdrop of ice-blue water and lush vegetation she demonstrated methods for measuring soil respiration (a combination of root respiration and microbial/insect respiration) at the base of a large cottonwood tree. In addition, she placed leaf litter bags of known tree genetics into a small tributary stream of the Hoh River and collected aquatic insects from the cobbly bottom. It was a gorgeous summer day spent in one of the most pristine river systems in Washington State.

The crew has featured beautiful locations all of the world, but this will be the first episode filmed in the US.  The show is primarily carried on stations throughout Europe.  We were thrilled to have the opportunity to share our work with “Guardians of Nature” and an audience on the other side of the planet.  The two segments will likely be available early spring 2012 and will be posted to our website as soon as they are available.

Frog Predator Response Experiment at CCCC

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.

in Ecological Research Education Evaluation Prison Life Science

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.

Frog Project Initiates New Research

Over the winter inmates in SPP’s Oregon Spotted Frog (OSF) program at Cedar Creek Corrections Center (CCCC) have been caring for frogs from Northwest Trek, the Oregon Zoo, and the Woodland Park Zoo that were too small or unhealthy for release into the wild. The frogs have thrived under the offender’s constant care and are slated for release late this winter. By caring for the undersized frogs, CCCC has helped the zoos save money and staff time as they prepare for the new frog rearing season and tend to the many species of animals in their care.  The experience has also provided more hands-on science training for offenders.

The CCCC frog program is expanding its rearing space from one tank to four and will accept twice as many frog eggs this season. Using four tanks will allow side-by-side comparison of frogs from two locations, Conboy Lake and the Black River. Conboy Lake frogs may grow larger and faster due to their exposure to invasive bullfrogs.

These Oregon Spotted Frogs show healthy growth and will be released this winter.

Washington Department of Fish and Wildlife Senior Biologist Marc Hayes suggested the comparative study at CCCC to to test this hypothesis and its implications for frog conservation. Partnering with SPP allows graduate students and offenders the unique opportunity to participate in this research.

To help reduce costs and the carbon footprint of the program, the SPP OSF team has also expanded and improved cricket breeding at CCCC.  After many trials and errors, and incorporating tips provided by experts, SPP staff and offenders are now creating a cricket husbandry manual.  The manual will be used to train the next group of offenders and students working on the project and may also help other facilities interested in sustainable source of crickets.

Cedar Creek’s Captive Crickets

by

in Ecological Research Education Prison Life Science Sustainable Operations

By Graduate Research Associate Jill Cooper

This past spring, Cedar Creek Corrections Center and the Sustainable Prisons Project began experimenting with a new captive rearing project to raise crickets.  The goal of the project is to create a more sustainable, stable supply of food to meet the demand created by housing a growing population of endangered Oregon Spotted Frogs. Crickets are one of the largest expenses for the frog project. Cricket suppliers are located out of state.  Long-distance shipping complications can impact frog feeding schedules, and definitely increase the project’s carbon footprint. As a result of these issues, the offenders at CCCC decided they would try their hand at cricket husbandry and breeding.

Few organizations in Washington raise their own crickets. Most suppliers, including pet shops, purchase crickets from out of state breeders.  By locally-growing crickets for the Oregon Spotted Frog conservation project, SPP offenders and staff are taking another step toward creating a more sustainable, cost effective, and stable food supply.

Inmates and scientists are discovering best practices for rearing crickets.

The Project is also contributing to scientific knowledge, compiling best practices protocol for raising crickets in temperate climates through trial-and-error experimentation. While visiting with offenders to check on how things have progressed, SPP Research Associate Jill Cooper was impressed to see how much the offenders had learned through observation and experience, in such a short amount of time. One inmate explained to her how the current batch of “breeders” that were delivered to the prison, “aren’t really the age which the cricket farm said they are.”  He pointed to the “ovipositor” or egg-depositing tube noting that they were obviously under developed and not ready to lay eggs yet.  Crickets chirp to indicate when they are ready to breed.  The inmate is considering starting his own cricket farm when he is released to offer a more sustainable source of crickets to customers here in the northwest.

Training Officer Ron Gagliardo of Amphibian Ark recently made a visit to CCCC to advise inmates and staff on the cricket rearing operation.  Previously from the Atlanta area, Ron has extensive experience with frog and cricket rearing.  He was a tremendous resource.  The inmates were able to ask him many questions and his input will undoubtedly improve upon the initial success of the cricket operation.

There have been many bumps along the way, but things have been looking up for the cricket operation.  Offenders are able to raise crickets to help supplement the frog’s diet, and have learned much in the process. While the cricket project can not yet support all the food needs, we estimate that the current operation will eventually support at least half of the crickets needed to feed about 200 frogs.

Releasing frogs at Joint Base Lewis-McChord

It has been another successful season rearing Oregon Spotted Frogs at Cedar Creek Correction Center.  A total of 1,346 were released into a wetland site on Joint-Base Lewis-McChord.  The four rearing institutions (Oregon Zoo, Woodland Park Zoo, Northwest Trek, and Cedar Creek Corrections Center) came together to release this year’s batch of frogs into the wild; a collaborative effort to stabilize the native populations.

The Sustainable Prisons Project has been working with Washington Department of Fish and Wildlife and Cedar Creek Correction Center (CCCC) to raise endangered Oregon Spotted Frogs since 2009. CCCC boasts having the largest frogs of any participating rearing institution, with100% of this year’s frogs large enough for release into the wild.

CCCC’s rearing success can be attributed to the amount of time and attention the offenders are able to give the frogs.  The offenders form genuine bonds with the frogs; some are given names, like “Lefty” or “NASCAR.”  The few deceased frogs have been placed in an offender-created “frog cemetery,” with hand-made gravestones.  One of the inmates patiently waits with his hand in the frog pond, and frogs will often come sit in his hand to be pet.

Cedar Creek Frog Maintenance

The day of the release, the frogs were loaded into containers and driven north to Joint-Base Lewis-McChord and their new home. CCCC is a minimum security pre-release facility, sometimes referred to as “camp,” where offenders are sent with minimal time remaining on their sentence. For participating offenders, the release of the frogs in part symbolizes their own impending release back into society.

Superintendent Doug Cole and Classification Counselor Marko Anderson of CCCC along with SPP Student Research Associates Liesl Plomski and Jill Cooper had the opportunity to release some of the frogs.  “It was a sight to see all 1,346 frogs hop into the water and instantly disappear with their well camouflaged bodies,” said Cooper.

Red coloration indicates healthy growth

Each frog has a micro-chip and will be tracked by volunteers who regularly visit the wetlands to conduct research, using special wands that detect the frogs’ signals.

At the conclusion of the release, 29 of the frog “runts” from other institutions were taken back to CCCC because they were not large enough to be released.  These frogs will be nurtured during the winter and released in the spring.  One offender says that this new batch of frogs is, “more skittish than the last;” hardly any of the frogs come sit in his hand.  Nevertheless, they are rapidly growing.  In just the past few weeks, the frogs have gained weight and are already beginning to show some red coloration. With another successful year of frog-rearing logged, the future looks bright for the Cedar Creek frog team.

Outreach at the South Sound Science Symposium

By Graduate Research Associate Jill Cooper

On October 27, 2010, former and current Sustainable Prisons Project Research Associates Liesl Plomski and Jill Cooper attended the South Sound Science Symposium on Squaxin Island where they represented SPP’s Oregon Spotted Frog Captive Rearing Project at Cedar Creek Corrections Center in Littlerock, WA.

The symposium provided an opportunity to network within the South Sound’s scientific community and spread the word about the great success SPP conservation projects have experienced in the past year.  Plomski and Cooper presented a scientific poster at the symposium describing the Project, garnering  interest in the Project from symposium goers.

The symposium proved to be a great outreach and learning opportunity for Sustainable Prisons Project staff and event attendees. “It was wonderful to see the wide array of cutting-edge environmental work being done in the Puget Sound area,” Cooper said.
