Willamette NF’s Northwest Forest Plan Land Use Allocations (lrmpPub) MA14a & b (mgmt_alc field) and AMA & Matrix (Withhd field) -> “harvest-able” the rest of the USFS area -> “other” Timber area Other areas

Partial harvest of stands 51-91 YO Assume 75% of area available for harvesting will actually be harvested Don’t harvest again for 25 years (min) Model States Size classes: small (10-15 “) & medium (15-20”) Annual transition probability =.75 /# years in a state
