The National Park Service is proposing to develop a new management plan for controlling invasive nonnative plants throughout Mesa Verde National Park and Yucca House National Monument in southwestern Colorado. Currently the park and monument have known populations of dozens of nonnative plants, many of which are highly aggressive competitors with native species. Their continued spread puts at risk the ecological and historical integrity of park landscapes.

The purpose of the plan is to enhance the current strategy at the park and monument for preventing and managing invasive plant occurrences in order to protect natural communities, ecological processes, cultural resources, visitor enjoyment, and other park values. The plan will focus on two broad goals: 1) Detecting and preventing the establishment of new invasive plant species or occurrences, and 2) Controlling new and existing priority occurrences of invasive plants.

Management alternatives will incorporate an integrated pest management approach and may consist of a variety of methods including mechanical, chemical, biological, manual and cultural control techniques.

An environmental assessment (EA) will be prepared in compliance with the National Environmental Policy Act (NEPA) to provide a decision-making framework that analyzes a reasonable range of alternatives to meet project objectives, evaluate potential issues and impacts to park resources and values, and identify mitigation measures to reduce the degree or extent of these impacts.

The National Park Service encourages public participation throughout the NEPA process. The public has two opportunities to formally comment on the project: once during initial project scoping and again following release of the EA. Currently we are in the scoping phase of this project. We invite you to submit your written comments online at the NPS Planning, Environment, and Public Comment website at If you are not able to submit comments electronically though this website, then you may submit written comments to the National Park Service at the address below. Comments must be received by February 14, 2014 in order to be considered during preparation of the EA.

Before including your address, phone number, email address, or other personal identifying information in your comment, you should be aware that your entire comment, including your personal identifying information, may be made publicly available at any time. While you can ask the National Park Service in your comment to withhold this information from public review, we cannot guarantee that we will be able to do so.
