  1. Mountain Pine Beetle Data Presented by Anina Hundsdörfer

  2. Plot locations E ? G F A B

  3. 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 Measures distance and angle to object aimed at with a laser beam • Height measurements • for all trees (DBH>1cm) • Total height (tip of terminal) • Lowest branch • Lowest live branch

  7. Data format

  8. 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.
