Or. Admin. R. 629-642-0500 - [Repealed effective 1/1/2024] Leaving Green Trees and Snags along Small Type N Streams subject to Rapidly Moving Landslides

(1) The purpose of this rule is to provide a source of large wood that can be moved by rapidly moving landslides into Type F or Type SSBT streams.

(2) When directed by the State Forester, operators must retain green trees and snags required for harvest type 2 or type 3 units under ORS 527.676 adjacent to small Type N streams subject to rapidly moving landslides likely to deliver wood to Type F or Type SSBT streams.

(a) The green trees and snags must be retained within an area that is 50 feet on each side of the small Type N stream and 500 feet upstream from a riparian management area of a Type F or Type SSBT stream.

(b) Requirements under OAR 629-623-0300 supersede the requirements of this rule.

(3) Operators are required to retain all green trees and snags in the area described in subsection (2)(a) of this rule up to the number determined by the equation H - T where:

(a) H is the total number of green trees and snags required to be retained in the harvest type 2 or type 3 unit; and

(b) T is the number of trees retained in riparian management areas in the harvest unit that may be counted as harvest unit leave trees under OARs 629-642-0100(11) and 629-642-0400(12).

(4) An operator may propose a plan for an alternate practice to meet the purpose of this rule. Alternate practices may include but are not limited to placing wood directly in the Type F or Type SSBT stream.

(5) This rule takes effect on October 1, 2007.
