Despite the granite getting all the fame, the trees of Yosemite provide a unique perspective that most visitors rush by without noticing. The next time you ascend into the park, keep a close eye on how the forests change before your eyes. They’ll let you know what kind of climate you’re in!

It’s All About the Zones

One of the most interesting things about Yosemite’s makeup of forests is it’s based on elevation. Due to the Sierra Nevada’s abrupt rise from almost sea level to twelve or thirteen thousand feet, this creates a quick change in climate as you ascend. Instead of a harsh sedimentary-like transitions to each zone, it’s a gradual fade from one layer to the next.

As you enter Yosemite from the west, you’re sitting at just above 2,000 feet in sea level. At this height, it’s known as the Foothill forest or Sonoran Zone. The summers are long, hot, dry, and arid. The prevalent tree you’ll find here is the Oak. More specifically, you'll see species like the Valley Oak, California Black Oak, Interior Live Oak, and the Canyon Live Oak.

If you have the windows open to your car as you make the climb, you may begin to smell the incense cedar. It's called this because the tree’s oil contains an incense-like odor. Their beauty is just as captivating as the odor which smells exactly like pencil shavings. As John Muir once so eloquently said, “no waving fern-frond in shady dell is more unreservedly beautiful in form and texture or half so inspiring in color and spicy fragrance."

Mariposa Grove, Giant Sequoias, Hiking, Yosemite National ParkGiant Sequoia in the Mariposa GroveWe know what you’re going to ask next. So, where do the Giant Sequoias live? All the “giants” including the kings themselves are at about 5,000 feet in elevation. Here you’ll find the groves filled with the Giant Sequoias. This is also where California’s largest pine resides – the Sugar Pine. Averaging up to 200 feet in height, they’re just as tall as the average monarchs but skinnier.

Cool fact: The Sugar Pine's cones are among the largest in the world averaging a foot long and up to 22 inches in length.

As you exit the main timber belt, you'll begin to ascend into what is called the Sub-Alpine Forest. This is just above the snow-line, meaning these evergreens get pummeled with snowfall in the winter months. They need to be hardy and take the weight of all that white fluff. At the same time, they get A LOT of water due to this snowfall. Here you’ll find Jeffrey Pines, red fir, white fir, and lodgepole pines. If you do see a deciduous tree at this elevation, it’ll be the quaking Aspen, named after their leaves which flutter in the wind.

The top range of the High Sierra, or as it's scientifically known, is the Alpine. At the lower elevations of this band, you’ll still find some of the species from the sub-alpine like the red fir, western white pine trees, and lodgepole pines. But this is where only the hardiest species can survive due to the long and cold winters. The mountain hemlock and white bark pine are the main brutes that can take it up here to the timberline.

Yosemite Valley – The “Eden” of the Park

One last thing to highlight is Yosemite Valley as it is the true exception to the rules above. It may sit at an elevation around 4,000 feet, but due to its topography, it provides the biggest variety of species. Just below the southern great wall, you’ll find vegetation you’d see at that elevation. While on the north side, it’s so warm that you’ll find plant life growing that you’d traditionally only see in the foothill region.

This is by no means a comprehensive run-down of all the trees you’ll see in Yosemite but rather an introduction into how the forests of Yosemite are comprised. The old saying might be “stop and smell the roses”, but in Yosemite, take your time and fully enjoy the forest. Those tall elders say a lot more than just rustling in the wind.
