Elevation is key to defining a tree’s neighborhood

Many factors contribute to the relative suitability of a growing range for each species of tree. While soil composition, moisture, slope direction, inter-species competition, microclimate, and history of fire each play a role, elevation is the most important factor in defining a tree’s “neighborhood.” As elevation increases, temperatures decrease and moisture levels rise. Trees that require more water and can withstand colder temperatures tend to be found higher on the slopes. Other species that can withstand higher temperatures and drier soils grow at lower elevations.
