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.

Bird Conservation Project Taking Flight at Stafford Creek Corrections Center

Purple Martins and Western bluebirds are two of the most charismatic birds of the Pacific Northwest. As the newest hands-on project of the Sustainable Prisons Project, inmates at Stafford Creek are constructing bird houses that will serve as habitats for the threatened Purple Martin and Western Bluebirds. The inmates have been enthusiastic about constructing the boxes and learning about the birds they are helping to preserve. To date, 16 Purple Martin boxes have been made and taken to Northwest Trek, where they will be installed and monitored for long-term conservation use. 150 Western Bluebird boxes have already been made and will soon be installed and monitored at various locations. Local lumber retailers (Tumwater Home Depot, Mary’s River Lumber Co., and Windfall Lumber) have donated all of the wood being used to make the boxes, making this project possible.

On April 28th, undergraduate research assistant Sarelle Caicedo and graduate research assistant Carl Elliott will be giving a joint educational lecture at Stafford Creek on Western bluebird and Purple Martin Conservation and Northwest prairie plant ecology. We are hoping that this lecture will increase interest in ornithology and the environment, and that this will kick start a series of future lectures given by undergraduates specializing in ecology and environmental studies at Evergreen.

Saving frogs takes teamwork

Washington State inmates Harry and Al are not the only people raising endangered Oregon spotted frogs for the Washington Department of Fish and Wildlife (WDFW). In addition to offenders and staff at the Cedar Creek Corrections Center, there are multiple rearing institutions involved in this five-year WDFW project, including the Greater Vancouver Zoo, Mountain View Conservation and Breeding Centre, Northwest Trek, Oregon Zoo and Woodland Park Zoo.

Comprising what we call the “OSF community,” our frog-farming comrades have missions dedicated to wildlife conservation and talented staff who consult our team on many occasions. We simply couldn’t succeed without their insightful guidance, typically shared on line with Cedar Creek staff member Marko Anderson, who then relays feedback to Harry and Al inside the prison.

As of August 18, Cedar Creek has 68 fat, healthy frogs destined for wetlands in Fort Lewis next month. Since early April, when WDFW scientist Marc Hayes delivered 80 eggs in tiny yogurt tubs, only 12 frogs have died. A careful balance of food, heat, clean water and loving care has resulted in an excellent 85% rate of survivorship – more than ten times the average outcome in the wild.

For an endangered species teetering on the edge of extinction, that’s good news. Soon, Cedar Creek’s frogs will join those from other rearing institutions in their new home at Fort Lewis. Like everyone involved in this effort, Harry and Al are proud to help amphibian diversity sustain its foothold in the Pacific Northwest.
