Invasive plant species installation; written notification to property owners, civil penalty.

Replaced plain text headers with formatted layout including page numbers, bill identifiers, and session dates.

The document format changed from an 'Enrolled' act to a 'Substitute' amendment, indicating the bill is being reconsidered by a different committee (Agriculture, Chesapeake and Natural Resources) with a new sponsor (Delegate Pence).

Removed the 'Enrolled' status and chapter designation, which signifies the bill was previously finalized and signed into law but is now being amended or reconsidered.

Added header information identifying the bill as a substitute amendment proposed by the House Committee on Agriculture, Chesapeake and Natural Resources.

The penalty for non-compliance changed from a civil fine (up to $250) to a Class 1 misdemeanor for first-time violations.

The penalty structure now includes escalating fines: $500 for a second violation and $1,000 for each subsequent violation.

The specific Code of Virginia section amended was changed from 3.2-802 to 3.2-809.

The requirement to amend section 10.1-104.6:2 regarding the creation and updating of the invasive plant species list was removed from the final enacted text.
