英文摘要	Planting native riparian trees can help recover wildlife and fish habitat on a local scale, when full recovery of natural processes that sustain riparian ecosystems is infeasible. To help improve planting success, we determined which environmental factors and management practices most influenced survival of planted Populus fremontii (Fremont cottonwood) in a field experiment on the San Rafael River, Utah, U.S.A. We planted 474 approximately 2-m-tall trees and tracked survival for 1.25 years. We used logistic regression to evaluate whether tree height, elevation above the river channel, distance to existing cottonwood or Salix exigua (coyote willow), soil conductivity, soil texture, planting depth, planting method (mechanical auger vs. hand-digging), and provision of natural and commercial supplements affected survival probability. Survival probability decreased with elevation above the river channel bottom and was greater in auger-dug than hand-dug holes. Survival probability was lower in soils with the highest salinity levels and was lower in sandy soils than soils with silt and clay. Survival may be improved by planting well above the channel to avoid flooding impacts but within 2 m above the channel in auger-dug holes to ensure access to soil moisture. Testing soil salinity and texture in areas with suitable elevation could also help improve survival. Approximately 35% of trees survived to the end of the study period, indicating that planting can help recover riparian habitat locally, especially if survival is improved in future planting efforts. However, full recovery of desired riparian habitat throughout the floodplain will require natural flows.
