This year, the Emergent Vegetated Mat (EVM) program grew fifty mats for the Samish Indian Nation. Each mats was 15-feet-long and embedded with native wetland species Carex exsiccata, Glyceria elata, and Juncus supiniformis. Program technicians were instrumental in improving germination protocols, resulting in early spring plant growth. These young plants were ready for transplanting into the coconut mats by early summer. Again thanks to improved cultivation techniques, the plants grew vigorously; by September, the lush growth covered 80% of the mats’ surface. 

We rolled up the mats in October, put them in a 24-foot truck without good shocks, and drove them to the Samish Indian Nation–a bit of a loud and  bouncy ride. Access to the planting site was by water, so we unloaded the mats into a warehouse and drove back south.

The restoration site is along the Samish River in an area recently confirmed as inhabited by the state-endangered Oregon spotted frog. Employees and volunteers from the Samish Indian Nation boated the mats to the site. They unrolled each mat and staked it in place. With the help of our prison-grown mats, they hope to improve the site’s native plant communities and create a better home for Oregon spotted frogs.
