What Tree Is That? West Coast Quick Reference
Leaves blow around forty feet up and change with the season. Bark stays put and it's right at eye level, which makes it the fastest tell for the three trees people mix up constantly: redwood, madrone, and eucalyptus.
Thick, deeply ridged, spongy. Push a fist into it and it gives.
Smooth reddish bark peeling off in papery curls, cool underneath.
Hangs in long loose ribbons, sheds constantly, litters the ground below.
My roommates and I do the free version of a weekend trip pretty often: pack sandwiches, split gas three ways, drive up the coast, hike wherever doesn't need a permit. Cheapest "vacation" that still feels like one. I got tired of every tree in my photos being captioned "big tree" though, so I actually learned what I was looking at. Screenshot the card before your next drive.
How Tall Should It Be
Height alone won't nail it, but it rules out a lot fast. If something's a scrubby 20 feet tall, it's not a redwood no matter how red the bark looks. Ranges below are typical mature size, not hard limits.
Coast Redwood200–300+ ft
Douglas Fir150–250 ft
Eucalyptus100–200 ft
Western Red Cedar100–175 ft
Pine (Monterey/Ponderosa)80–150 ft
Bigleaf Maple50–100 ft
Coast Live Oak30–70 ft
Pacific Madrone20–60 ft
Coastal Fog, Foothills, or Mountain
Location does half the work before you even look at a leaf. These bands aren't hard lines, but they're close enough to narrow things down fast.
Redwoods, Pacific madrone, and coast live oak cluster right along the coastline, where the fog keeps things cool and wet all year.
Bigleaf maple, coast live oak, and planted eucalyptus groves show up in the warmer inland valleys and lower hills.
Douglas fir, pine, and western red cedar take over as you climb, where it's drier and colder for more of the year.
Where People Get It Wrong
Same mistakes, over and over, from tourists and locals both.
Pines, firs, cedars, and redwoods are different families. Bundled needles mean pine, single needles mean fir, scales mean cedar.
Pacific madrone flakes red and orange too. Check the leaves, broad and smooth, before calling it a redwood.
A young redwood or a stunted mountain pine won't fit the typical range yet. Height narrows it down, it doesn't confirm it.
Cones, acorns, and dropped bark are often the fastest confirmation. No need to identify the whole canopy from below.
It's an Australian import planted across California since the 1850s. Extremely common, not original to the coast.
Smell It, Touch It, Check the Ground
Sight isn't the only sense that works here. Half of these are faster with your hands than your eyes.
