The main juniper species of California:

• The common juniper (Juniperus communis) is a low, mat-forming shrub (seldom more than 1 m tall). It is widespread in mountains and has only needle-like leaves. (See Bryce Canyon National Park for a Utah specimen.)
• The California juniper (Juniperus californica) is a shrub or tree. It is up to 8 m tall, with a round seed cone (which can be bluish brown).
• The Western juniper (Juniperus occidentalis) is a tree prevalent in the Sierra Nevada. It is usually 10-30 m tall, with an oblong seed cone (which can be purple-red to blue).

The cone of the gray pine is massive, heavy, and bearing at the tips upcurved claws. The needles are 15-32 cm long and are held mostly in bundles of 3 in a persistent sheath. The gray pine is moderately fire-adapted; its short life span and prolific cone production are typical for pines, which are usually killed by fire but shed seeds that quickly reestablish the forest. The name digger pine is common in older books and internationally, but is now regarded as disrespectful of the Native Americans who formerly gathered the seeds of this pine. The seeds, which have vestigial wings, are distributed primarily by Steller's jays (Cyanocitta stelleri)) and Western scrub-jays (Aphelocoma californica), which gather them and bury them in caches, much as squirrels bury nuts.

Scree is a collection of broken rock fragments at the base of crags, mountain cliffs, volcanoes, or valley shoulders that has accumulated through periodic rockfall from adjacent cliff faces. Landforms associated with these materials are often called talus deposits.
