Small mammal survey begins

A survey has begun for the rodent and shrew population along the Las Vegas Wash.

Conducted quarterly, the survey utilizes Sherman box traps and pitfall traps to target the different species of small mammals.

Past surveys of this kind took place in 2002 and 2010, identifying 12 species of small mammals.

The survey continues throughout all four seasons of 2023.
