T hese units includ e: 4.21, 4.3, 5.11, 5.13, and 5.41. Assum ing that significant new road construction was unlikely we clip p e d all areas that were m ore than 0.25 m iles from an existing road . We then rem oved a 100 foot b uffer from each sid e of rip arian areas. T hen we exclud e d all terrain >30% slop e.

T hese regeneration cut activities includ e d clearcuts, p atch clear cuts and overstory rem oval cuts. We then sorted the rem aining foreste d areas b y d om inant tree sp e cies and wild life hab itat structure stage (H S S). Since the vast m ajority of hab itat structure stages and tree size classes are closely correlate d we d id not further refine the sorts with size class categories.
