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 4^th 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.
