Proof of ownership is required to harvest or transport timber, forest products, or other native vegetation in Utah. This includes Christmas trees and seeds. Transport would typically be via a vehicle driven on a road in Utah. The proof can be as simple as a purchase receipt, or a written letter of permission from the landowner. For more information see Utah code sections:
78B-8-602 Proof of ownership
Contrary to popular belief, our state flower (the Sego Lily, Calochortus nuttallii) enjoys no specific legal protections. But like any other native plant material, landowner permission is required for removal and a written permit if transported on a Utah highway. Moral/ethical considerations also apply. Native plants usually do not survive being transplanted and many require specific soils and/or have other special requirements. Grow native plants from seed or purchase locally grown native plants appropriate for your area.
Other than the proof of ownership requirement (above), Utah has few laws that afford any protection whatsoever to native plants. However various federal laws do come into play (see below).
Plants or parts thereof may not be removed or destroyed in U.S. national parks
Federal agencies require permits and even these permits do not allow the removal of special status plant species/varieties nor their seeds on federal lands:
U.S. Forest Service-Collection Permits
Utah BLM - seed collection
U.S. Fish & Wildlife
