Revegetation Implementation and Monitoring along Las Vegas Wash
The Las Vegas Wash (LVW) carries more than 170 million gallons of water a day.
Decades ago, the flows of the LVW created more than 2,000 acres of wetlands.
By the 1990’s, only about 200 acres of wetlands remained.
The dramatic loss of vegetation reduced both the LVW’s ability to support wildlife and serve as a natural filer for water that flows to Lake Mead, the source of our community’s water supply.
As the lead agency of the Las Vegas Wash Coordination Committee (LVWCC), the SNWA has been implementing revegetation projects in the Clark County Wetlands Park for more than 14 years.
Due to the 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.

Keeping Half the Profits Beats Non-profits for Social Impact
Melbourne social enterprise Who Gives A Crap sold nearly 3 million rolls of toilet paper in 2014/15 and gave half the proceeds to WaterAid Australia, but co-founder Simon Griffiths says the donation would have been less had the startup adopted a non-profit model when it launched two years ago.
