VariablesStatus• Alive: Live tree with DBH > 1.0 cm.• Seedling: Live tree from germinants to sapling with a DBH<1.0 cm.• Snag: Standing dead tree with an intact terminal• Log: Recent year fallen tree that may or may not lying on the ground• Stump: Dead tree with a broken terminal, regardless of height

Species• DF: Douglas fir (Pseudotsuga sp.) • FIR: Amabilis fir (Abies amabilis Dougl. ex J. Forbes )• HM: hemlock (Tsuga sp.)• LP: lodgepole pine (Pinus contorta)• TA: trembling aspen (Populus tremuloides)• WS: white spruce (Picea glauca (Moench) Voss)• WWP: western white pine (Pinus monticola)

Variables cont.DBH• Tree diameter at breast height (1.3m) for all live and dead treesHeight• HT: Total tree height of live and dead trees• BHT1: First live branch height measured from the ground. HT - BHT1 = crown depth• BHT2: First dead branch height measured from the ground. Infestation• AttYR: year of attack: 2001- 2004• Bsp: beetle species (occasionally more than one attacked one tree)• AttSt: attack status:

– S: strip attack– M: mass attack– R: Resisted

• Timing: time of year when the attack occurred– 1: June– 2: July– 3: August– 4: September– 1.5: mid June/July– 3.5: mid August/September

Notes column

Notes• Dead top: Trees with a dead terminal, either the needles

had completely fallen off or died recently.• Declining: Trees with poor health and expected to die in

the coming years• Dying: Trees that were dying.• Dying top: Trees with a terminal that was dying.• Flat top: Trees had a flat crown due to the death of the

terminal some years ago.• Leaning: Trees that were tilted, whose height could not

be accurately measured.
