Existing roads, Trails and Landings. 13,112 ha of existing roads, trails and landings are removed from the productive land base. This compares to 11,745 ha from TSR3. The roads included major and minor highways, regional access, forest service roads and minor logging roads and spurs. Road, trail and landing data was complied through TRIM and licensee roads. A buffer width of 10 meters was used on all logging roads. An overlay of the roads with previously logged blocks indicated that most blocks had roads either accessing or passing through them. Due to the completeness of the supplied licensee road data it was determined that the existing buffer widths were sufficient to account for in block disturbances. This differs from TSR 3 where a further 4.9% aspatial netdown was applied to stands less than 31 years old to account for existing landings and in-block disturbances, and 13 m width was applied to major roads. A 0.4 ha area netdown was applied to permanent landings for this data package. Table 14 shows the netdowns for permanent roads and landings in the Xxxxxxx TSA.

Existing roads, Trails and Landings. The Okanagan TSA analysis accounted for existing roads using a reduction to all productive forest polygons (5.4% in stands age class 0 through 2 and 0.6% in older stands). For this analysis, to facilitate meaningful spatial analysis, roads in the TRIM file were buffered as follows to identify the area removed to the non-productive category.
