Revegetation Implementation and Monitoring along Las Vegas Wash

impact on wetlands by the installation of erosion control structures throughout the LVW, the SNWA conducts wetland revegetation to mitigate for that loss as required by U.S. Army Corps of Engineers 404 permits. Ground disturbance within the temporary footprint of the construction activities surrounding the wetland areas requires revegetation to comply with Nevada Division of Environmental Protection (NDEP) stormwater permits. Other funding obtained to assist in the construction of erosion control structures requires the creation of additional revegetation areas not already being created for permit mitigation. Revegetation sites require frequent visitation, oversight and occasional remediation often for a minimum of two years after initial planting. Such activities include but are not limited to irrigation, adjustment of irrigation components, herbivore control, the sporadic removal of vegetative debris and/or other debris deposited by storms and natural events, and invasive species removal when required to benefit the site. After the initial two years, oversight is typically less intensive and occurs on an “as-needed” basis. To properly document and report the success of mitigation to permitting agencies, annual monitoring must take place for revegetated sites. Annual monitoring of the success of the various irrigation practices, planting techniques and plant choices provides the LVWCC with pertinent information to make future decisions that will improve the success of the revegetation program.
