Methodology Total station Shoots a laser beam to prism located next to tree x, y, z coordinates of each tree
4
Methodology Each tree receives a tag
5
Methodology Caliper DBH recorded for all trees with DBH>1cm Ultrasound For measuring distance to hypsometer
6
Methodology Hypsometer Height measurements for all trees (DBH>1cm) Total height (tip of terminal) Lowest branch Lowest live branch Measures distance and angle to object aimed at with a laser beam

Variables Status 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)
9
Variables cont. DBH Tree diameter at breast height (1.3m) for all live and dead trees Height 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
10
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.
