Chemistry can be as important as texture when it comes to bark as a habitat. Temperate rainforests grow in cooler parts of the world, such as the northwestern United States and southern Australia. * Many species tend to be very slender and tall to reach the upper canopy and absorb much of the sun.

Since the first six to eight inches (15-20 cm) of soil is a compost of decaying leaves, wood, and other organic matter, it is the richest source of nutrients on the ground. To counter this, the oak must spend a greater proportion of its metabolic resources producing tannins to make the bark unpalatable. "We found large-scale evidence that bark thickness is a fire-tolerance trait, and we showed this is the case not just in a particular biome such as a savanna, but across different types of forests, across regions and across continents," said first author Adam Pellegrini, a NOAA Climate and Global Change Postdoctoral Fellow at Stanford University who led the study while a graduate student in Princeton's Department of Ecology and Evolutionary Biology.
