DESCRIPTION
The Fine project is located at the confluence of Beaver Creek and the Methow River. Much of the existing riparian vegetation has been removed with just scattered cottonwoods and small groves of riparian shrubs remaining. During high flow periods Beaver Creek overflows its banks and runs into a series of poorly defined channels and shallow ponds on the lower portion of the site. Sandropseed (Sporobulus cryptandrus) is the dominant grass cover on the upland portion while smooth brome (Bromus inermis) is the dominant grass species on the lower slope. Non-native species are common throughout the site. Soil types are dominated by a sandy loam and a sandy cobble structure. The goals of the project are to create better channel definition and flow return to the mainstem Methow and to restore a functioning riparian buffer. The buffer will be constructed as a series of planting zones which will create habitat function but still allow view corridors to the river. Plantings will be protected with small deer enclosures and receive drip irrigation. The river bank on the property consists a fine sandy soils mixed with cobble. The bank has been experiencing significant erosion over the past few years. Establishing vegetation along the bank and slowing erosion is a goal of this project.
The project began in 2011, with the establishment of three planting enclosures, the construction of a new channel to allow better connectivity with a side channel, and the installation of willow on the sandy beach area to revegetate the bank zone. The disturbed area was then seeded, and drip irrigation and woodchip mulch were installed with all plantings, and previous riparian plantings on-site were incorporated into the new irrigation system. A revetment was constructed to remediate an eroding bank, with willow bundles planted additionally to provide long term vegetative stability. The hope is that these willows will release above browse height in 2014. Survival levels are at 82%, and vegetation is exhibiting vigorous growth. Limited weed issues have been dealt with by hand-pulling and mowing to prevent seed production.
