The Rocky Mountain exotic plant project is designed to determine (1) what exotics are capable of invading disturbed sites in major vegetational (environmental) zones of the Northern Rocky Mountains and (2) whether they are capable of invading near-climax closed vegetation in these zones. As an accessory activity we are determining (3) what natives are invading the same disturbed zones since we hope to find, among them, species likely to be successful on these sites and therefore species that might competitively exclude exotic invaders. A second accessory project of interest to managers, but with less immediate scientific value, was designed to (4) record the present distribution of major weeds along roadsides of Grand Teton National Park as they were recorded in Glacier during 1983-84.
