Abstract

The rate of invasion of Tamarix pentandra Pall. into the vegetation bordering Utah Lake, Great Salt Lake, Colorado River, and Green River in Utah was determined from historical information and scientific studies. There are no records of tamarix at the above listed lakes and streams prior to 1925. The period from 1925 to 1960 was one of rapid spread and increase in importance of tamarix. The greatest degree of invasion occurred from 1935 to 1955. At the present time, naturalization is occurring along the mountain streams and reservoirs of the Wasatch Mountains.
