Forest health issues shall be addressed by a tiered system.

(1) The first tier is intended to maintain forest health and protect forests from disturbance agents through the voluntary efforts of landowners. Tier 1 is the desired status. Consistent with landowner objectives and the protection of public resources, forests should be managed in ways that create, restore, or maintain healthy forest ecosystems so that disturbance agents occur or exist at nonepidemic levels. To the extent of available funding, information and technical assistance will be made available to forestland owners so they can plan for and implement necessary forest health maintenance and restoration activities.

(2) The second tier is intended to manage the development of threats to forest health, or address existing threats to forest health, due to disturbance agents. Actions by landowners to address such threats to forest health are voluntary except as required under chapter 76.04 RCW to reduce the danger of the spread of fire. Actions suggested to reduce threats to forest health are specified in forest health hazard warnings issued by the commissioner of public lands under RCW 76.06.180. Within available funding, site-specific information, technical assistance, and project coordination services shall be offered as determined appropriate by the department.

(3) The third tier is intended to address significant threats to forest health due to disturbance agents that have spread to multiple forest ownerships or increased forest fuel that is likely to further the spread of fire. Actions required to reduce significant threats to forest health are specified in forest health hazard orders issued by the commissioner of public lands under RCW 76.06.180(5). Within available funding, site-specific information, technical assistance, and project coordination services shall be offered as determined appropriate by the department. Landowners who are provided notice of a forest health hazard order under RCW 76.06.180(5) and fail to take the action required under such order may be subject to increased liability for the spread of fire as described in RCW 76.04.495 and 76.04.660. However, a private landowner need not take actions required under the third tier, and may not be held liable for the failure to take such actions, where the disturbance agents on the private landowner's land spread from state or federal lands or where the presence of disturbance agents on state or federal lands would limit the effectiveness of actions required on the private landowner's land under the third tier.
