Annual marsh bird surveys begin

In April, permitted biologists begin annual marsh bird monitoring at the Wash, surveying emergent wetland habitat for a variety of marsh bird species, with special attention to the federally endangered Yuma Ridgway’s rail.

Although potentially suitable nesting habitat has existed along the Wash channel for many years, field crews rarely detected the species before 2021, despite conducting annual surveys since 2000.

Annual detections of 5 to 7 rails over the last three years represent a significant boost, indicating that the LVWCC and its partners have increased the suitability and availability of appropriate habitat and the rails are taking advantage.

Wildlife research

Get your hands dirty for a great cause at the next Green-Up!

Held once a year in the spring, our Green-Up planting events along the Las Vegas Wash are great for conservationists and activists of all ages and create much-needed habitat for wildlife, reduce erosion and improve water quality. While this year's event has already taken place with 210 volunteers planting more than 3,500 native trees and shrubs, registration for the next Green-Up will open in January 2025.
