REFERENCES

Information from multiple sources has been consolidated and generalized, e.g., one might find trees outside of the specified elevation and geographic limits. Generally elevation decreases as latitude increases. Likewise commonly found height descriptions are given, but trees can grow much larger in favorable situations, and some trees have a shrubby form at high elevations or seacoast. Diameter (DBH), refers to diameter at about 4.5 feet, diameter at breast height.

I've been fortunate to have excellent professors and instructors at the University of California, Santa Barbara, and Merritt College, Oakland. I have relied extensively on the books and websites listed below.
