Key Concepts in Riparian Restoration

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.

 

Background and introductory resources:

Historical background on the extirpation of beaver from the Pacific Northwest:

A potpourri of concepts, beaver habitat does not persist without beaver, water storage volumes numbers:

Guidebook created as a result of the work at Bridge Creek:

Pollock et al. 2018

Beaver habitat as fire-breaks and refugia:

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

Bitteroot

Bitteroot

Bitteroot blooms on north-facing cliffs in western North America.

The Paiute name for bitteroot is kangedya. Traditional Native American uses of the plant included eating the roots, mixed with berries and meat, and using the roots to treat sore throats.
