Provide for Arbor Day Plates and the Home of Arbor Day Plate Cash Fund and change provisions relating to license plates

Nebraska bill LB 568 creates "Arbor Day Plates" for vehicle registration and establishes the "Home of Arbor Day Plate Cash Fund" to receive revenue from these specialty plates. The fund will provide grants for projects related to Arbor Day or tree conservation, though specific grant recipients aren't detailed in the bill text. The legislation also eliminates outdated provisions related to other specialty license plates and harmonizes existing plate regulations. This is a procedural change affecting vehicle owners who choose to purchase the Arbor Day plate, with no direct impact on other license plate types beyond the eliminated provisions.
