Utilizing Buffaloberry (Shepherdia canadensis) for Ecological Restoration in the Pacific Northwest

The Pacific Northwest, an ecological treasure trove, has witnessed significant environmental degradation over the years due to urbanization, deforestation, and other anthropogenic influences. Restoring its natural habitats, particularly its vital riverbanks and salmon habitats, requires innovative approaches. One such strategy involves the native Shepherdia canadensis, also known as Buffaloberry. This versatile shrub offers an array of benefits for ecological restoration, from reinforcing riverbanks to supporting salmon habitats.

Harvesting Buffaloberry Seeds

Before discussing the benefits of Buffaloberry in restoration projects, it’s essential to understand how to harvest its seeds efficiently.

Timing is Key

Optimal Harvest Period: Seeds are best harvested in late summer to early fall when berries are vibrant red or orange.

Avoid Overripe Berries: Berries that have become overly soft or begun ferment may have compromised seed viability.

Gathering and Cleaning

Manual Picking: Gently pick the berries from the shrubs, not damaging the branches.

Separation Process: Using a fine mesh sieve, separate the seeds from the pulp by gently pressing and rubbing the berries against the sieve’s sides.

Rinsing: Once separated, rinse the seeds thoroughly in cold water to remove any remaining pulp residues.

Drying and Storage

Air Drying: Spread the seeds in a single layer on a paper towel or cloth, letting them air dry in a shaded, cool location for several days.

Cool Storage: Store the dried seeds in a sealed container in a cool, dry place. For extended viability, consider refrigerating the seeds at temperatures between 33°F and 41°F.

Bankside Restoration

The erosion of riverbanks poses significant threats to the stability of aquatic ecosystems in the Pacific Northwest. Here’s how Buffaloberry can aid in bankside restoration:

Soil Stabilization: Buffaloberry’s robust root system binds the soil together, preventing erosion and ensuring the bank’s structural integrity.

Nitrogen-Fixing Abilities: The shrub’s association with nitrogen-fixing bacteria enhances soil quality, promoting the growth of surrounding native plants.

Shade Provision: Its dense foliage provides shade, maintaining cooler water temperatures necessary for native aquatic species’ survival.

Salmon Habitat Restoration

Salmon, a keystone species in the Pacific Northwest, has seen dwindling numbers due to habitat destruction. The Buffaloberry can play a pivotal role in rejuvenating their habitats:

Food Source for Wildlife: The berries attract birds and other fauna, creating a thriving food web for a balanced aquatic ecosystem.

Bankside Shelter: The shrub’s thickets provide refuge for smaller creatures, creating an environment rich in prey for young salmon.

Water Quality Maintenance: By stabilizing banks and reducing sediment run-off, Buffaloberry helps maintain more transparent waters, which is essential for salmon health.

Specific Use Cases

The Skagit River Restoration Project

In a recent project along the Skagit River, Buffaloberry was integrated to:

Stabilize Newly Formed Sandbars: Newly formed sandbars were prone to erosion, but with Buffaloberry planting, they’ve been successfully consolidated.

Support Local Fauna: Birds like the Cedar Waxwing, which feed on the berries, have seen an uptick in numbers, enhancing the river’s biodiversity.

The Salmon Creek Revival

In the Salmon Creek watershed, restoration experts have:

Established Buffer Zones: Buffaloberry shrubs were planted to create buffer zones, filtering pollutants and reducing sediment run-off into the creek.

Enhanced Streamside Habitats: By incorporating Buffaloberry, streamside areas witnessed increased insect populations, providing ample food for salmon fry.


Shepherdia canadensis (Buffaloberry) is more than just a native shrub; it symbolizes ecological hope for the Pacific Northwest. Environmentalists and restoration experts can harness its capabilities to heal the landscapes and waterscapes that define this pristine region by understanding its cultivation, benefits, and potential use cases. As we move forward, integrating native species like Buffaloberry will be vital.
