Scott River Riparian Woodland Revegetation Projects. (French Reach)

摘要

Planting efforts of 197 continues riparian revegetation efforts along the ScottRiverfunded by the Klamath Restoration Program (FY 1995 and Jobs in the Woods). The 'New Years Flood' of January 1, 1997 moved the Scott River near the confluence with French Creek approximately 400 feet to the east, altering the area to be planted considerably. The flood measured 34,300 cfs at the peak discharge, ranking it the forth largest recorded with a 14.4 year occurrence interval. The 1997 plantings were conducted on the gravel and sand bars deposited near the mouth of French Creek after the flood. The advantages of planting the sites included: no competing vegetation and rodents, some areas with fines (nutrient) deposition, newly formed backwater areas and proximity to the water table (approx. 3 feet). Survival on the large bar opposite of the French Creek confluence, the 'Center'. average 77% 'good' survival ('good' = plant alive, vigorous, healthy). Survival on French Creek Bar was 51% 'good'. High mortality on the French Creek Bar may be attribued to heat transfer and reflection from the sandy substrate.
