Key Concepts in Riparian Restoration

Cliff   Website

Whether you’re learning about restoring streams and rivers for the first time, or you’re a life-long beaver believer, this list of resources will provide additional information on both how and why ONDA focuses on restoring beaver habitat in our riparian restoration programs.

Western Rattlesnake

Western Rattlesnake

Also known as the Great Basin Rattlesnake, these pit vipers have buff-tan coloring and small, oval blotches to blend into their arid surroundings. Small heat-sensing indentations on each side of the snake’s snout detects warm-blooded prey for better striking accuracy in the dark. Source: The Oregon Encyclopedia

Latin name: Crotalus oreganus lutosus

Beavers - So what?

When the High Desert Museum installed a new exhibit dedicated to beaver in 2021, ONDA's Riparian Restoration Coordinator Jefferson Jacobs helped out with the design.

In this talk, he delivers fact after beaver fact, always diving deeper to discover the "so what?" behind these facts. You will learn a ton about beavers and their important role in the desert ecosystem. This presentation starts with interviews of four artists commissioned to create public artworks in conjunction with the museum exhibit; JJ's talk starts at 15:00 minutes in.
