Celebrating a Successful Inaugural Season for the Butterfly Program at Mission Creek

Celebrating a Successful Inaugural Season for the Butterfly Program at Mission Creek

by Graduate Research Associate Dennis Aubrey

The Sustainability in Prisons Project’s newest program, the rearing of Taylor’s checkerspot butterflies at Mission Creek Corrections Center for Women, has just concluded its first season. A second generation of more than 3500 caterpillars has now safely gone into diapause, and the effort can officially be considered a complete success. Some of the season’s highlights include:

More than 700 Taylor’s checkerspots were released onto South Puget Sound prairies. Six hundred of these were released as post-diapause caterpillars in early March, placed one at a time on available host plants. Another 101 were released as adults, following breeding and oviposition. These were placed carefully on nectar flowers or, if they chose to, simply allowed to flutter off across the prairie.

Breeding activities were also highly successful. Males and females were crossed according to specific lineage pairings designated by staff at the Oregon Zoo to preserve genetic diversity. Seventy-two mating introductions were made, with 32 of these resulting in a successful pairing. From these, 3,515 eggs were laid. 3,395 of these successfully developed into healthy caterpillars and entered diapause, a survivorship of 96.6%.

A novel research project was carried out at the facility, examining host plant choice by female checkerspots. This work is showing that they prefer to lay eggs on two native plants, harsh paintbrush and Washington-endangered golden paintbrush, over the exotic but well-documented host English plantain. This finding has the potential to alter restoration practices for the butterfly and possibly unite the recovery efforts for both it and the golden paintbrush.

Currently, in addition to caring for the 3,624 caterpillars in diapause at the facility, inmate technicians are working on end-of-season reporting, putting in host plant gardens around the greenhouse and tending the plants, and creating a butterfly coloring book for children visitors to the prison. Their work with the butterflies this season has been exemplary in every way, and the overwhelming success of the project’s first year is thanks to their tireless and meticulous work.

SPP Butterfly Internship Experience

SPP Butterfly Internship Experience

by SPP Undergraduate Intern Chelsea Oldenburg

Editor’s Note: SPP has had the pleasure of working with three wonderful Evergreen undergraduate interns during this spring quarter.  Over the next few weeks, blog visitors will have the chance to read about their experiences in the students’ own words.

After 8 weeks of working with the Sustainability in Prisons Project at Mission Creek Corrections Center for Women as an intern for the butterfly program a lot of unexpected things have become commonplace for me. It’s amazing how quickly I acclimate to my surroundings. After only a few days of visiting, the prison guards, razor wire and coveralls seemed normal. As does manipulating the curled proboscis of a butterfly with a paper clip and watching her perfectly paint plantain leaves with bright yellow eggs.

So far my main work this quarter has been facilitating an oviposition preference study that Dennis Aubrey is doing for his masters thesis. This means observing which plants female Taylor’s checkerspot butterflies prefer to lay their eggs on.

The women are carrying out the study five or six days a week and so Dennis, Caitlin (another intern) or I rotate coming out to insure things are running smoothly, bring supplies and run a few of the preference trials ourselves. Usually we also get a chance to help with some of the daily chores of captive rearing. These chores include: feeding adult butterflies a honey-water mixture from a q-tip, transferring eggs into various containers with a paintbrush, freshening water and supplying plantain leaves to hungry caterpillars. Aside from housekeeping and study overseeing there is a lot of time to converse with the women from MCCCW that are working on the project. They seem to truly love the butterflies they are raising and I am always impressed by their fastidiousness, acute observations and consistent positive attitudes. The love seems to go both ways as the butterflies flourish under their care.  A couple of weeks ago I was sent home from The Oregon Zoo with many more larvae, pupae and adult butterflies to bring to MCCCW because of the success with their current stock. Maybe the women at Mission Creek can care for these transforming insects from a place of real understanding as they simultaneously undergo incredible personal transformations themselves.

For the last few weeks of my internship I am excited to erect some raised beds around the butterfly rearing greenhouse. After the frames are built and a lot of soil is shoveled in, we are going to fill the beds with native prairie plants, larval food plants and nectar flowers for feeding the adult butterflies. Two of the women I work with seem genuinely excited to help with the project. Although I will be sorry to end my visits to the prison at the close of this quarter it feels good knowing I will leave behind some nourishing infrastructure.

Inmates Participate in Egg Mass Surveying at West Rocky Prairie

Inmates Participate in Egg Mass Surveying at West Rocky Prairie, 2.28.12

By SPP Graduate Research Associate Andrea Martin

When Julie Tyson, a biologist with the Washington Department of Fish and Wildlife, took me and the two inmate frog technicians that are raising endangered Oregon Spotted Frogs (OSF) at Cedar Creek Correctional Center (CCCC), and two officers out to look for OSF egg masses, I was afraid I would walk right past them, or worse, step on one.

Lucky for all us egg survey newbies, Julie found the first one. It became pretty obvious that they would be hard to miss. The egg masses are very dark, and float at the surface of the shallow water in wetland areas like West Rocky Prairie. West Rocky Prairie, also known as Beaver Creek, is just 13 miles south of Olympia, and less than a mile from Millersylvania State Park. The site is one of a handful of areas in Western Washington where the endangered frogs lay eggs every season.

Oregon Spotted Frog season is now upon us, and the site of the nearly-black gelatinous spheres is the first sign of the reproduction of the endangered species. Soon, a few hundred OSF eggs will be brought into CCCC and several other institutions, and the rearing process will begin.

In total, we found 19 egg masses.  Thirteen were found on the West side of Beaver Creek, of these, 10 were new. On the East side, where our group was the first to survey of the year, we found six.  Several of the egg masses had freeze damage because of the erratic late-winter/early spring weather. It’s likely that the frogs have stopped laying for now until the weather warms a bit; Julie estimated that the most recent egg masses we found were 2-3 days old.

In addition to the OSF egg masses, the inmates, officers and I found many Northwest Salamander egg masses, which are gelatinous, but solid as a baseball. Despite the freezing weather, and threat of snow, the inmates really enjoyed the opportunity to get outside the prison walls, and to learn more about the project they are working so hard on.

This will be the 4th season that inmates at CCCC have raised endangered frogs. Both of the inmates who will be responsible for feeding the frogs, keeping them warm and safe and recording all the changes they will go through in their life cycle are veterans of the rearing process. They were new, however, to the first step of finding the eggs.

The inmates’ participation in the egg surveying at West Rocky Prairie shows a new level of trust and desire to collaborate between SPP and its partners. The frogs that are raised at CCCC are the biggest and healthiest of all of SPP’s rearing partners, due in large part to the amount of time and attention the inmate frog technicians are able to give to the animals. The frog rearing program at CCCC has been highly successful, and its importance has been recognized by SPP’s partners, other scientists, and the prison community. This contribution was a major factor in the decision by the Department of Corrections to allow the inmates to participate on Tuesday.

SPP Plant Profile: Golden Paintbrush (Castilleja levisecta)

SPP Plant Profile: Golden Paintbrush (Castilleja levisecta)

By Graduate Research Associate Evan Hayduk

Basic information: Castilleja levisecta is an endangered perennial herb that can grow up to 20 inches tall and is covered with soft, sticky hairs.  Occurring in open grasslands in the Puget Trough, the species used to be common from British Columbia to the Willamette Valley in Oregon.  Now only a few populations remain, mostly in the area of the San Juan Islands and in the Puget Sound prairies.  Similar to other prairie species, populations have declined due to loss of habitat to agriculture, residential, and commercial uses.  The suppression of fire disturbance, a vital component of the prairie ecosystem, has also led to the decline of populations (see previous post on Prairie Fires).  The U.S. and Washington Department of Fish and Wildlife are actively reintroducing this species that nearly went extinct within the last two decades.

Ecological Importance:

Golden Paintbrush is relatively short-lived, with individual plants only surviving for 5-6 years.  Although it tends to grow in clumps from one to fifteen stems, it seems to reproduce only through seed.  As mentioned in previous posts, paintbrush species are hemi-parasitic.  Studies have shown Golden Paintbrush that were established with Roemer’s Fescue (Festuca roemeri), were more successful after outplanting than those established alone or with Oregon Sunshine (Eriophyllum lanatum).  Other studies have shown that Castilleja levisecta grown in a greenhouse with Eriophyllum lanatum were larger than with other host species.  Pollinators of Golden Paintbrush are currently being studied, but previous research described a species of bumblebee (Bombus californicus) as an active pollinator.

Fun Facts:

Paintbrush species are known to actively absorb selenium, which is a mineral that is toxic in high concentrations.  This is an unexplored use of paintbrush for reclamation of areas contaminated with selenium.  The dense growth nature of Castilleja levisecta may make it the most useful for this purpose.

Inmate Frog Technicians Experiment with Cricket Rearing

Inmate Frog Technicians Experiment with Cricket Rearing

by: Inmate Frog Technicians at Cedar Creek Corrections Center

Editor’s note: Below is a message from our frog technicians at CCCC, who are currently experimenting with raising crickets to feed to the endangered Oregon spotted frogs being reared at their facility.

On 10/16/11, we received 65 over-winter frogs from a handful of sites. When received, frogs were about as big as dimes. Now they have grown to the size of half-dollars. They are doing very well, very good coloring, spotting on top and red on bottom.

When frogs were received, four frogs looked very bad and have since died. I don’t know what exactly was wrong with them, all I know is they would not eat and were very thin because of it. Except for that, everything has been going very smoothly.

We have now started a new cricket project. We have always bought our crickets from Fluker Farms to breed, but we have been unable to breed multiple generations with them.  Recently we got Jamaican Black Crickets from Woodland Park Zoo and we feel that we could breed a generation of these crickets.  What we hope to do is cross-breed European crickets with these Jamaican Black Crickets and try to get the long life span from the Jamaican but the easier edibility of the European House Crickets we buy from Flukers.

We are going to get 2500 European crickets (5 weekers) and 2500 Jamaican crickets (5 weekers) and raise them side by side, do everything the same between the tanks, food, water, temperature, etc. We are hoping to see which cricket is a more efficient candidate for our cricket project. And also see which crickets we can raise generations from.

In a totally separate experiment, we want to get 500 of each style crickets and raise them together in one tank, hoping to cross-breed these two crickets, getting traits from both.   We’ll see if that may be the best candidate for our cricket program.

Cricket Traits:

European House Cricket: The more popular of the cricket species, these crickets can grow up to 2cm in length. They are more extensively fed to reptiles. Easily digested.

Jamaican Black Cricket: These crickets grow fast and get bigger, probably reaching 3-4cm in length. In my experiences these crickets live longer and are easier to breed, but might be harder for the frogs to eat when they get too big.

DOC Enables Former Frog Technician to Join in the Annual OSF Release Event

DOC Enables Former Frog Technician to Join in the Annual OSF Release Event

by Graduate Research Associate Sarah Weber

The Sustainable Prisons Project is so excited that we were able to include one of our former frog technician inmates at the annual frog release this year!  Harry Greer has worked with the Oregon spotted frog project at Cedar Creek Corrections Center since the project’s inception in 2009.  This season Harry raised the frogs at CCCC until July when he was moved to work release.  Department of Corrections staff at CCCC went above and beyond to accommodate and clear Harry for attendance at the release event.  Many thanks to Superintendent Doug Cole, Captain Charlie Washburn and Classification Counselor Marko Anderson; it was a real joy to see Harry releasing the frogs he so carefully raised.

Annual Oregon spotted frog release!

Annual Oregon spotted frog release!

By Graduate Research Associate Sarah Weber

On a crisp fall day at the end of October, participating Oregon spotted frog (OSF) rearing partners gathered for the annual frog release at Joint Base Lewis McChord (JBLM).  The OSF, received by each institution in egg form, are reared from March to October when they are released as healthy juvenile and adult frogs onto three wetland sites located at JBLM.  This is a fun day that all the partners look forward to each year.

The Sustainable Prison Project frogs were transported from Cedar Creek Corrections Center (CCCC) in ten shoebox-sized Tupperware containers lined with wet paper towels. Upon arrival, the containers were taken to the waters edge where lids were removed.  Some frogs were anxious to get out and immediately jumped onto the shore and into the water, while some needed a bit more time and coaxing.   Once in the water, the frogs quickly camouflaged themselves by digging into the sandy bottom or swimming into marshy vegetation.   The water in the wetland is cool, but open and exposed to sunlight, with nice shallow areas along the banks.  OSF are highly aquatic and leave the water only for short periods of time to forage for food.  They move between ponds via connecting waterways, making them especially vulnerable to habitat fragmentation.  The wetlands at JBLM offer a large undisturbed habitat with many channels for migration and shallow warm water for breeding in the spring.

This year, we released 163 healthy, large adult OSF raised at CCCC.  The frog technician inmates, as always, did a wonderful job rearing our captive population.  It is not always possible to raise each frog to releasable size, and each year SPP takes all undersized frogs from our rearing partner facilities, and supports them through the winter at CCCC.  This year we received more than 60 frogs to over-winter.  The inmates will raise them until springtime when they will also be released on the wetlands at JBLM.

WDFW Research Scientist Dr. Marc Hayes recently brought visiting scientist Dr J. Michael Conlon to visit the Oregon spotted frog operation at Cedar Creek Corrections Center (CCCC). Dr. Conlon is a Professor of Biochemistry at Weill Cornell Medical College in Qatar, and is an internationally known biochemist whose research interests are focused on the purification and characterization of naturally occurring, biologically active peptides. He has worked on skin peptides for more than 40 years and with frog skin peptides for more than 10 years.

A large, healthy Oregon spotted frog

Dr. Conlon is interested in studying the skin peptides of the Oregon spotted frog (OSF) because they are very high in anti-bacteria and anti-fungal properties. The OSF also show a resistance to the amphibian chytrid fungus, known to be decimating amphibian populations worldwide.  The answer to why OSF are resistant to chytrid might be found in their skin peptides.

To better understand this, purified skin secretions need to tested for their activity against several strains of chytrid, requiring three steps: 1) obtain the skin secretions; 2) purify the individual peptides from those secretions; and 3) test each individual peptide from the skin secretions on several strains of the amphibian chytrid fungus.

SPP helped facilitate step 1, and steps 2 and 3 will be done in the UAE and at Vanderbilt University in Nashville, TN.   SPP and the frog interns at CCCC were pleased to be involved with this research as it will contribute significantly to the scientific knowledge of why OSFs are resistant to chytrid.

Butterfly Rearing Commences at Mission Creek

Butterfly Rearing Commences at Mission Creek

By Graduate Research Associate Dennis Aubrey

The first painted lady butterfly to eclose in the SPP lab at Evergreen.

At long last, the wait is over. After almost a year of preparation, the butterflies have finally arrived! Inmate technicians at Mission Creek Corrections Center for Women (MCCCW) have been caring for painted lady larva for almost three weeks now, and over the weekend they got to watch their first butterflies emerge from their chrysalid.

The painted ladies are being reared as a training surrogate for the endangered Taylor’s checkerspot, which inmates will begin to work with next February. These training butterflies were chosen for their relative hardiness and fast life cycle, which will allow the inmates to go through several complete revolutions before graduating to the much more delicate Taylor’s checkerspot. So far the inmates involved have surpassed expectations in every way.

As the final phases of greenhouse construction were being completed, the student intern on the project, Dennis Aubrey, began rearing painted ladies at the Sustainable Prisons Project (SPP) lab on The Evergreen State College (TESC) campus. This was done to work out the fine details of adapting the Taylor’s checkerspot rearing protocol for use with the painted ladies, and to prepare for training the inmates at the facility. Following this, 200 painted lady eggs were ordered and delivered to MCCCW, where eager inmate technicians began learning how to care for these delicate insects.  Working with butterflies in the SPP lab approximately two weeks ahead of the ones at MCCCW was incomparably helpful in training the inmates effectively.

Inmate butterfly technicians at MCCCW caring for painted lady caterpillars and recording observations

From the time they began, the inmates have been taking very detailed carefully drawn notes, and have been tending to their charges with the patient meticulous care that makes all the difference in rearing projects such as this. At SPP’s frog project at Cedar Creek Corrections Center, the large amount of time inmates dedicate to caring for the endangered Oregon spotted frogs has led to the largest specimens raised at any institution. Last week, when Dennis visited Mission Creek to check on the inmates’ progress, he couldn’t help but notice that the painted lady chrysalids were significantly larger than he was able to produce in the SPP lab. Whether that’s a factor of the light and beneficial conditions in the greenhouse, or is directly attributable to the increased daily care, it’s hard to say. Either way, it’s a great sign of things to come for the future success of the project.

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.
