Division 630 - HARVESTING
Section 629-630-0900 - Western Oregon Harvests; Slopes Model

(1) For the purpose of OAR 629-630-0905 through 629-630-0925, designated debris flow traversal areas and designated sediment source areas are determined by the slopes model and displayed on department maps and the department's reporting and notification system. The slopes model also identifies which designated sediment source areas contain trigger sources, which help prioritize designated sediment source areas for selection as slope retention areas. Department maps and the department's reporting and notification system display designated sediment source areas and distinguishes those with trigger sources. The slopes model designations can be viewed at the time of submitting a notification of operation to the State Forester.

(2) Definitions in section (1) of this rule are defined in OAR 629-600-0100.

(3) All trees retained, as required for OAR 629-630-0905 through 629-630-0925, that otherwise meet the requirements for leave trees may count toward requirements for wildlife leave trees within harvest type 2 or harvest type 3 units, pursuant to ORS 527.676. Operators are encouraged to leave trees that meet the requirements for wildlife, leave trees within harvest type 2 or harvest type 3 units, pursuant to ORS 527.676, immediately adjacent to seeps and springs, as described in OAR 629-655-0000.
