Overview
Oregon's trees split sharply at the Cascades: lush conifer rainforest to the west, drier ponderosa pine and juniper country to the east. A few needle and bark clues tell the big conifers apart.
This guide covers common and iconic Oregon trees — how to tell them apart by foliage, bark, and habit. Pair it with a photo of the needles or bark and the app to confirm any tree you find.
Key Species to Know
Douglas-fir
Pseudotsuga menziesii
The Oregon state tree — a giant conifer with soft, flat needles and cones bearing distinctive three-pronged bracts between the scales. The backbone of the timber industry.
Western Redcedar
Thuja plicata
A large conifer with flat, scale-like foliage in fern-like sprays, drooping branch tips, and stringy reddish bark. Fragrant and rot-resistant.
Bigleaf Maple
Acer macrophyllum
A broadleaf tree with enormous five-lobed leaves — the largest of any maple — and mossy limbs in the wet coastal forest. Turns gold in fall.
Ponderosa Pine
Pinus ponderosa
A tall pine with long needles in bundles of three and orange, jigsaw-plated bark that smells of vanilla. Dominant in the dry country east of the Cascades.
Western Hemlock
Tsuga heterophylla
A graceful conifer with short, uneven flat needles and a drooping leader at the treetop. Regenerates thickly in the shade of the coastal forest.
Oregon White Oak
Quercus garryana
The main native oak of the Pacific Northwest — a rugged tree with rounded-lobed leaves and gnarled limbs, anchoring the Willamette Valley's oak savannas.
Seasonal Guide
- Fall: bigleaf maple and Oregon white oak add gold to the mostly evergreen landscape.
- Year-round: the big conifers — Douglas-fir, redcedar, hemlock — keep the west side green.
- Look for orange, vanilla-scented plated bark to pick out ponderosa pine on the east side.
Safety Reminder
This is an identification guide only — it does not cover edibility or foraging. Observe trees without damaging bark or breaking limbs, and stay on established trails.
