Experimental riparian vegetation treatment activities would be implemented by NPS under the proposed action and would modify the cover and distribution of riparian plant communities along the Colorado River. All activities would be consistent with NPS Management Policies (NPS 2006) and would occur only within the Colorado River Ecosystem in areas that are influenced by dam operations. NPS would work with tribal partners and GCMRC to experimentally implement and evaluate a number of vegetation control and native replanting activities on the riparian vegetation within the Colorado River Ecosystem in GCNP and GCNRA. These activities would include ongoing monitoring and removal of selected nonnative plant species, systematic removal of nonnative vegetation at targeted sites, and native replanting at targeted sites, which may include complete removal of tamarisk (both live and dead) and re-vegetation with native plants. Treatments would include the control of nonnative plant species and revegetation with native plant species.

As part of LTEMP, experimental riparian vegetation treatment was included as mitigation for dam operations within CRE. Vegetation treatment actions on NPS managed lands will be implemented by NPS consistent with NPS Management Policies (NPS 2006) and will occur only within the CRE in areas that are influenced by dam operations. The NPS will work with tribal partners and GCMRC to experimentally implement and evaluate a number of vegetation control and native replanting activities on the riparian vegetation within the Colorado River Ecosystem in GCNP and GCNRA. These activities would include ongoing monitoring and removal of selected nonnative plants, species in the corridor, systematic removal of nonnative vegetation at targeted sites, and native replanting at targeted sites and subreaches, which may include complete removal of tamarisk (both live and dead) and revegetation with native vegetation. Treatments would fall into two broad categories, including the control of nonnative plant species and revegetation with native plant species. Principal elements of this experimental riparian vegetation proposal include:

• Control nonnative plant species affected by dam operations, including tamarisk and other highly invasive species;
• Develop native plant materials for replanting through partnerships and the use of regional greenhouses;
• Replant native plant species to priority sites along the river corridor, including native species of interest to tribes;
• Remove vegetation encroaching on campsites; and
• Manage vegetation to assist with cultural site protection.

General Plant Species

• Approximately 129 vegetation communities, Over 850 species have been reported from GCNRA, and over 1,750 vascular plant species from GCNP (NPS CFMP-EA_pg 19)

1. Riparian communities are dominated by species such as coyote and seep willows, arrowweed, western honey mesquite, catclaw acacia, and exotic tamarisk with many other species present.
2. Desert Scrub communities are dominated by species such as creosote, white bursage, brittle bush, ocotillo, four-wing saltbush, big sagebrush, ephedra, dropseed, brome grasses, and many other species.
3. Approximately 11% of flora in GCNP and GC reach is exotic.
