Fun Forest Facts

Three species of trees are commonly referred to as redwoods: California's coast redwood (Sequoia sempervirens) and giant sequoia (Sequoiadendron giganteum), and China's dawn redwood (Metasequoia glyptostroboides).

Spirals in Giant Sequoia Cones

If you look at a giant sequoia cone with the bottom end facing you, you will notice that the scales form spirals. This is the Fibonacci sequence found everywhere in nature: in the spiral of snail shells and in the shape of storms and breaking waves, for example.

Changing Fires Impact on Redwoods

Scientists recently took a look back at the history of fire in pine forests of the Southwestern US and discovered that the devastating megafires of recent decades are unprecedented. By searching for fire scars etched into the wood of ancient trees, they discovered that historic fires burned more frequently and were less intense. Today, fires burn hotter, spread more easily, and scorch the canopy which kills trees. These super fires devastate the landscape more than historic fires because the forest structure is now different after two centuries of logging, grazing, and other human activities including fire suppression. Young forests today are often overcrowded with trees and this allows flames to leap skyward into the treetops and spread quickly over the landscape.
