||Controlling exotic plant infestations is one of the most serious challenges facing the Southeast Utah Group (SEUG) managers, who are charged with the protection of natural and cultural resources. Exotic plants are infesting Arches and Canyonlands National Parks and Hovenweep and Natural Bridges National Monuments at an alarming rate. Of over 96 exotic trees, herbaceous plants and grasses occurring in the parks, 19 species have been identified as a threat to SEUG natural resources. The exotic plant management plan will assist the parks in managing this threat to ecosystem health and function and will provide a framework for cooperation with land managers, neighbors, and partners with common concerns.
The preferred alternative was selected and includes the judicial use of mechanical, cultural, chemical, and biological control techniques, based on a thorough analysis of the problems and a balanced approach to solutions.This plan outlines the techniques and processes for exotic plant removal in the SEUG for the next five to ten years.
