Partnering to protect the Upper Las Vegas Wash.



The Eglington Preserve is an area of sensitive habitat located on National Parks Service lands within the city limits of North Las Vegas, Nevada. The Preserve area encompasses a portion of the Upper Las Vegas Wash which is a primary drainage for the entire Las Vegas Valley and is a major tributary to Lake Mead and the Colorado River.

Why TNC Selected This Site

The Eglington Preserve has a large population of State Listed Critically Endangered Las Vegas bearpoppy (Arctomecon californica) and the candidate for state listing, Las Vegas buckwheat (Eriogonum corymbosum var. nilesii). The area is entirely within the Las Vegas Formation, which is well known for its Pleistocene fossil resources.

What TNC Has Done

Of the 300-acre Eglington Preserve, TNC is restoring, enhancing and protecting 143 acres of active wash habitat and associated uplands. Protection, restoration, and enhancement activities will provide a number of benefits, including:

  • Improved ecological function of active wash drainages
  • Improved sensitive plant and wildlife habitat
