I recently traveled to Mission Creek Correctional Facility for Women (MCCCW), a Washington Department of Corrections (WA DOC) facility that has been closed since September 2025. For over 14 years before closing, MCCCW played a crucial role in native prairie habitat restoration and species recovery through SPP’s Taylor’s Checkerspot Butterfly Program. This program is an ongoing collaboration between SPP, Department of Corrections, and Washington Department of Fish & Wildlife (WDFW) to restore the population of this keystone species, which contributes to the overall health of Washington State prairies. The health of prairie ecosystems and the future of the Taylor Checkerspot Butterfly (TCB) are closely connected, with each relying on the other for survival. Prairies supply the essential ingredients butterflies need, like specific host plants for their larvae, nectar for adults, and the right seasonal patterns to guide their life cycle. In turn, the butterfly plays a role in supporting pollination, contributing to food webs, and reflecting the overall condition of the ecosystem. Because prairie habitats are so limited and vulnerable, declines in the TCB often point to deeper environmental challenges, such as reduced plant diversity or shifts in climate timing. Protecting this butterfly, therefore, goes hand in hand with restoring prairie landscapes, helping to rebuild resilient ecosystems that support a wide range of species while maintaining important environmental functions.
When MCCCW closed its doors in September 2025, the incarcerated women were transferred to Washington Corrections Center for Women (WCCW). The federally endangered butterfly larvae, who were peacefully unaware of their looming migration, remained at MCCCW and rested in diapause. For three months, SPP made special trips to MCCCW to check on the larvae as they overwintered by providing food, checking environmental conditions, and tucking the larvae back in if/when they stirred too much. In December 2025, the larvae took the same 40-mile car ride their incarcerated caretakers had just a few short months before. Reunited at WCCW, technicians worked hard to ensure the larvae remained healthy through diapause until Wake Up in February 2026. From then until March, larvae were provided daily care at WCCW until all larvae were released back into the wild. This moment marked the completion of the first steps in plans that had been hatched by partner organizations when they learned about the impending closure of MCCCW.

Starting late 2024, SPP worked tirelessly with partners from WDFW, the US Department of Fish and Wildlife, MCCCW staff and leadership, WA DOC leadership, incarcerated technicians, and many other entities to determine the best course of action to relocate the TCB program from MCCCW to WCCW while keeping the program active and functioning. Knowing that proper rearing facilities would not be quite ready for the emerging butterflies in early spring, this collaboration had to devise a plan that worked for all parties involved. In 2025, DOC leadership and staff, TCB Technicians, and SPP crafted a plan to continue utilizing existing greenhouse infrastructure at MCCCW. In April 2026, WCCW transported technicians to their temporary job site at MCCCW to care for, measure, and monitor wild-caught adult butterflies. Technicians also needed to care for eggs being laid by the adults (as seen in the photo below) through development until they once again enter diapause and are transported back to WCCW, where they will overwinter until they too will emerge in the early months of 2027, this time in their brand-new lab at WCCW.

While speaking with the technicians, it was clear that they were not only passionate about their jobs but also deeply connected to the experiences of the butterflies in their care.
“We are so similar. We are both in captivity, you know? We’re both trying to recover and grow against the odds. At first, I just thought this job would be nice because the pay was better than our other options. I didn’t expect it to have such an impact on my overall well-being. We don’t really get that too much in here.”
I heard this sentiment echoed by several voices that day in the greenhouses, each expressing a mix of gratitude, reflection, and honesty. For some, the reality that not every butterfly will get to thrive outside of locked-up spaces felt personal. And yet, there was also a quiet sense of purpose, an understanding that every individual, whether released or not, contributes to something larger. In caring for these fragile species, the technicians are not only supporting the recovery of a federally endangered butterfly but also participating in the restoration of an entire ecosystem, leaving a lasting impact that extends far beyond the walls they work within.
This season there are 10 sub-adult turtles and 12 adult turtles in care at Cedar Creek, all of which have tested positive for E. testavorens. The 10 sub-adult turtles came to CCCC in August of 2025 and have been taking baths 3 times a week since. These sub-adults are also being periodically tested for E. testavorens, to assess the effectiveness of the terbinafine bath treatment. In addition to taking terbinafine baths 3 times a week, the 12 adult turtles also received treatments similar to past years with surgical removal of portions of the shell most severely impacted by the shell disease.
