Turning a new leaf with emergent vegetated mats!

In mid-October, SPP delivered our third batch of Emergent pre-Vegetated Mats (EVM) to wetlands at West Rocky Prairie, Joint Base Lewis McChord (JBLM) and Mima Creek Preserve. At these sites, the Center for Natural Lands Management (CNLM) is conducting an experiment using the mats as part of a reed canarygrass suppression strategy. Replacing the reed canarygrass with wetland plants will help restore habitat for the threatened Oregon spotted frog. This project is supported with funding and resources by the Washington Department of Fish and Wildlife, United States Fish and Wildlife Service, CNLM, and JBLM.

Prior to delivery, we rolled up the mats and let them drain for 24 hours. Even with reduced water, each mat weighs about 60 pounds when it is delivered—healthy roots and shoots are heavy!

Each mat contains a combination of native wetland plants: spreading rush (Juncus supiniformis), tall mannagrass (Glyceria elata), and creeping spike-rush (Eleocharis palustris). The mats were produced in Stafford Creek Corrections Center’s aquaponics greenhouse by a team of corrections staff, incarcerated technicians, and SPP-Evergreen staff.

Staff and volunteers from CNLM and JBLM lay three, 1-meter by 3-meter mats side by side and anchor them with biodegradable stakes.

At each site, the mats are arranged in squares, three meters on each side. Staff and volunteers from JBLM and CNLM prepared the sites using a variety of combinations of herbicide, mowing, and solarization to remove the reed canarygrass; on the day of mat installation, they removed dead grass and root material with weed cutters making it easier for the plants in the mats to make contact with soil and establish themselves quickly. Teams will revisit each square to determine which of the various reed canarygrass treatments best allowed the native wetland species to take hold.

At the site shown here, reed canarygrass was treated only by mowing; in the background, you can see its pre-mowing height of up to six feet tall. Sarah Hamman deploys a water depth gauge–believe it or not, this is a wetland!

Will the coconut coir mats prevent reed canarygrass from growing back? Will the native plants grow quickly enough to establish healthy populations, competing for space with the reed canarygrass? Stay tuned to find out!

Principle & Practice: Learning and doing science at Shotwell’s

In February, I visited Shotwell’s Landing and got to see the prairie restoration crew in action. The crew is contributing to program coordinator Conrad Ely‘s thesis research for the Master of Environmental Studies program. The research builds on the work of an earlier Master’s thesis investigating how treating seeds with plant-derived smoke water, which contains many of the same chemicals present in prairie fires, can affect their germination rates and vigor—many prairie species are very difficult to propagate, and they hope to trigger germination with treatments simulating prairie fire.

After the first nursery tasks of the day, program coordinator Conrad Ely shared a presentation on the scientific method. He tied principles of research design to their shared experiment, and then to Mima Mounds enigma. He used theories on the Mima Mounds’ formation to illustrate opportunities as well as limitations of the scientific process. From their experience with prairie restoration, the crew knows the Mounds well, and they jumped in with their own thoughts and theories.

My gratitude for everything the crew does for the region’s prairies. They are employed in prairie restoration full time, and their efforts and enthusiasm make a big difference for South Sound prairies, one of the most rare and threatened landscapes in the nation.

So Close to a Million Plants We Can Almost Taste It

SPP’s Conservation Nursery continue to thrive at three facilities in Washington State: Stafford Creek Corrections Center, Washington Corrections Center for Women, and Shotwell’s Landing Nursery. Since 2010, we have delivered almost 1,000,000 plants for restoration and habitat enhancement projects on Puget lowland prairies— just 33,000 more plants and we’ll be there! In 2013 we provided 375,000 plugs for prairie projects (see the table below); this is a 14% increase over what we produced the year before. We achieved the increase by adding nursery capacity at Washington Corrections Center for Women, plus increased support from the dedicated prairie restoration crew from Cedar Creek Corrections Center.

This was the first season for nursery production at Washington Corrections Center for Women (WCCW). The crew of five inmate technicians carefully cultivated and shipped 80,000 native prairie plants. They were particularly success at growing blanket flower, Gaillardia aristata, a species that in past years showed low germination and growth rates. The warmer conditions in the propagation hoop houses at WCCW proved to be just the environment that allowed this species to thrive. The Conservation Nursery program benefits enormously from having a new site with an enthusiastic crew of technicians and staff.

SPP’s Conservation Nursery continues to be a highly collaborative effort. Regional coordination is provided by the Center for Natural Lands Management (CNLM); they bring together managers responsible for prairie habitat to develop detailed restoration and habitat enhancement plans for the Taylor’s checkerspot butterfly. The plants cultivated by SPP’s Conservation Nursery directly benefit the regional stakeholders such as the Washington Department of Fish and Wildlife, the Department of Natural Resources, Joint Base Lewis-McChord, Wolfhaven International, and CNLM. This year we also increased the number of plants going to land managers of prairies in the northern portion of the Puget lowlands, Whidbey and the San Juan Islands; we hope to further those relationships in the future.

Though we came up just short of the magic number of 1,000,000 in the 2013, we feel confident that in 2014 we will blow right past that goal, and on to our next milestone!
