Ecosystem impacts of tamarisk (Tamarix spp.) management in the Arkansas River watershed, Colorado: effects of disturbance and herbicide residues on passive plant community restoration
… were used to quantify soil degradation rates for imazapyr and triclopyr from six sites in Colorado. A dose response study was then conducted at two of these sites to determine the relative sensitivity of important restoration plant species to the two herbicides. Exponential decay models estimated …
