Large Wood Structures

Large wood structures have been going in, and you may have seen them if you've been on the north end of the trail. What are they, and why are they important?

The kind being built now is a structure built entirely from natural materials; other types of structures are supported with chain and other materials like dolos (more on those at a later date).

Here's why they're important:

• Protection from Erosion: Placed on the banks of the newly built river channels, the structures help keep the channel from eroding while giving time for plants to establish.
• Creates Diverse Habitat: Large wood helps to form deep pools and gives space in between the wood that offer salmon resting places during migration and safe nurseries for young salmon to feed and grow, protected from strong currents, and predators.
• Provides Food: Decomposing wood releases nutrients, fueling the aquatic food web that feeds young salmon.

The project will install around 130 large wood structures and drive more than 1300 wood piles.
