High Desert Approved and Prohibited Plant List

Revised November 15, 2022

Fire Intensity & Propagation:

Many evergreen trees have resins, oils, and waxes that include flammable chemicals. These can easily be ignited and burned with high heat intensity. Their burning embers often propagate fires which can be carried by the winds to start spot fires. Dead branches in these trees enable flames to move up into the canopy. Shrubs touching the tree branches or trunk act as ladder fuels. Well-watered trees may reduce the concentrations of flammable chemicals and may burn with reduced fire intensity. Burning embers carried by the winds often start spot fires.

The trees below are Grandfathered (Trees previously allowed or naturally growing). Trees to tall for neighborhood but might be allowed in open spaces/arroyos. These include trees recommended by the city.
