| 説明 | BLM Alaska Forester Eric Geisler has a task that doesn’t have to do with trees. He has to figure out how much native seed is needed for revegetation or restoration projects statewide over the next five years. That’s about how long it takes to go from initial seed collection to processing, production, and storage for the necessary quantities.BLM Alaska’s Seeds of Success partners with several others to collect and promote the use of Native Seeds. The tree main partners are the Alaska Plant Materials Center, Alaska natural Heritage Program and the Chicago Botanical Garden Conservation Land Management Intern programs. The interns hired by Chicago Botanical Garden serve a five month term where they learn Alaska species and collect seeds and along with herbarium specimens. The interns work under the direction of the Alaska Natural Heritage program that helps BLM make decisions on where to collect seeds each year and which species to target. While the emphasis is always on species for revegetation or workhorse species, the Natural Heritage program and the interns collect as many other species as are available from the sites they visit throughout the summer. These collections are then sent to the Alaska Plant Materials Center for processing. Alaska’s Seeds of Success program collects seeds from over 50 geographically distinct plant varieties each year.Geisler says the Alaska Plant Materials Center, based in the agricultural suburbs of Palmer, cleans, tests, stores, and refreshes Seeds of Success stocks. The Center staffers increase seed quantities by planting collected seeds in either box gardens or fields to get enough seeds to meet projected needs. For the past few years, they’ve also provided native seed packets for BLM Alaska to hand out at the Alaska Sportsman Show and other events. The packets include messaging encouraging the use of native seeds rather than introducing potentially invasive species to Alaska.These seeds also become available for long-term storage, research, federal contractors, and other federal agencies involved with the BLM’s Seeds of Success program. The program goal is to have sufficient quantity of each variety for planned revegetation projects. Geisler visits the Alaska Plant Materials Center at least twice a year. The Center can be an interesting place to tour. Manager Brianne Blackburn, seed program manager Lyubomir Mahlev, and summer Seeds of Success interns can explain unique equipment such as the seed extractor, cleaners and filters, testers, and discuss breeding techniques. They also can point out the box gardens, cultivated fields, seed storage areas, and show what a “plug” is and how they plant them. Curious about what invasive weeds are showing up in Alaska? They are knowledgeable about that, too, and can show samples. The Seeds of Success program began when Congress created the Native Plant Materials Development Program in 2001. The program helps ensure a stable and economical supply of genetically appropriate native plant materials for use in restoration and rehabilitation efforts on public lands as well as preserving the genetic diversity through long term storage at the National Center for Genetic Resources Preservation in Fort Collins, Colorado. BLM administers the program and promotes cooperation among agencies. Geisler is always thinking ahead about seed needs and how to promote the program. Geisler hopes contracting specialists and program managers will plan ahead and remember to use the Seeds of Success program rather than importing seeds from outside of Alaska. It’s another way to fight invasive plant species and ensure a stable and economic supply of native plant materials. In plant lingo, that’s an “SOS.”Pictured here, Columbine flowers at the Alaska Plant Materials Center gardens. Photo by Kim Mincer, BLM Alaska. |
