Dense infestations of tamarisk as shown here along a small ephemeral stream in southeastern Utah, can also block flood flows, sharply altering patterns of erosion and deposition. Bailey et al. (2001) found that tamarisk leaf litter degrades more rapidly than that of native riparian trees and that this was associated with a two-fold decrease in aquatic macroinvertebrate richness and a four-fold decrease in abundance. Research conducted by University of Minnesota graduate student Ted Kennedy at Ash Meadows National Wildlife Refuge in Nevada has also shown that tamarisk infestations reduce diversity and biomass of native fishes (personal communication).
