Bill Williams River NWR is located at the northernmost edge of the saguaro’s range and is a unique feature of the landscape that provides habitat and food for everything from elf owls to white winged doves to javelina. Staff from Saguaro National Park in Tucson will be visiting to conduct a saguaro survey (census) on Friday, then will offer a public outreach session on Saturday.
We will learn some saguaro natural history, you can try your luck at estimating cactus height using a clinometer, take a guided nature walk, and get to know Arizona’s invasive species! This event is free and open to the public.
Bring hat, sunscreen, binoculars, walking shoes and water.
