Pacific Silver Fir is a tall evergreen tree native to the Pacific Northwest. It has two-toned needles, dark green on top with silvery undersides, giving the tree a distinctive appearance. The straight trunk and dense, symmetrical crown make it a striking forest species.

Pacific Silver Fir thrives in cool, moist, high-elevation forests. It is the most shade-tolerant of the true firs and among the most shade-tolerant of all native conifers, allowing it to grow beneath the canopy of older trees. It provides cover for wildlife and food from its seeds, while also contributing to the structure and stability of mountain forest ecosystems.

The species is harvested for timber and pulp and has been used ornamentally in some plantings. Well-suited for ecological restoration, naturalization, and habitat projects where native conifers are needed. Pacific Silver Fir lives up to its Latin name, amabilis, meaning “lovely,” in recognition of its striking appearance.

Sitka Spruce is a native conifer and the largest spruce species in the world. It grows quickly and reaches impressive heights, often reaching more than 50 metres (164 feet) in suitable conditions. It has strong, durable wood that has long been recognised for its commercial value.

It contributes to soil stability and plays an important role in coastal ecosystems. It offers cover and nesting sites for birds and small animals, and its seeds provide food for wildlife such as songbirds and small mammals.

Sitka Spruce plays a role in reforestation and ecological restoration projects in Coastal BC. It also holds historical significance: the Wright Brothers famously used Sitka Spruce to construct the frames of their first flying machines.
