In a case of too little too late, the Colorado Department of Agriculture has banned the sale of Russian olive (Elaeagnus angustifolia) by nurseries in that state, according to this article from the Glenwood Springs Post Independent. The invasive tree/shrub is already a major problem in Colorado, as it is in many part of the western U.S., and nurseries sell so little of it that the ban, which starts Jan. 1, 2003, will barely impact their sales. Hopefully this gesture will help build public awareness about the dangers of planting Russian olive and other invasive species. The Dept. of Agriculture is recommending people consider the native silver buffaloberry (Shepherdia argentea) as a replacement species.
