Close up of a Yuma Ridgway's Rail in the wetlands at the Las Vegas Wash

Annual marsh bird surveys begin

Annual marsh bird surveys at the Wash began last month and have kept up with last year’s record of five endangered Yuma Ridgway’s rails.

By the end of the first two rounds of surveys, biologists detected two individuals at Clark County’s in-lieu fee mitigation wetlands, one near Upper Narrows Weir and a possible pair near Homestead Weir.

Although areas of emergent marsh have existed along the channel for many years, field crews only reported the species a few times prior to 2021, despite annual surveys.

Counts over the last two years represent a dramatic increase, indicating that the Las Vegas Wash Coordination Committee (LVWCC) and its partners have increased the suitability of the habitat and the species is taking advantage.
