✦ Synopsis
Application. Seeding combinations of legumes, bunchgrasses, or sodforming grasses on blade scarified alluvial sites had variable effects on the reestablishment of 4 selected native competitors. No single seeding treatment effectively controlled all competitors, but prescriptions to control individual species or combinations of species can be developed. To reduce reestablishment of thimbleberry either bunch-or sodforming grasses should be seeded on scarified sites. Blade scarification alone, without seeding, effectively controls red elderberry and salmonberry. Red alder abundance and growth can be reduced by seeding legumes. Early survival and growth of Sitka spruce varied somewhat depending on seeding treatment. Sodforming grasses were more serious competitors than native plants and should not be used to control vegetation where Sitka spruce is planted. Abundance of red alder appears to be the most critical variable determining the long term success of Sitka spruce.
