2 Where are we now? Why spruce beetle? Why is it still going? How do we know? What can we do? What are we doing? Strategic planning Knowledge Experience Innovation Partnership

3 Why spruce beetle? life cycle: Dendroctonus rufipennis

4 Why spruce beetle? life cycle: Dendroctonus rufipennis

5 Why spruce beetle? life cycle: Dendroctonus rufipennis

6 Why spruce beetle? life cycle: Dendroctonus rufipennis

7 Why spruce beetle? life cycle: Dendroctonus rufipennis

8 Why spruce beetle? life cycle: Dendroctonus rufipennis

9 Why spruce beetle? 2 winters are tough! 40-60% of immature adults emerge and overwinter in the duff Warm blanket of snow and no woodpeckers

10 Why spruce beetle? Host trees are tough! Healthy trees are well defended Spruce beetles are normally relegated to weakened or dying trees

11 ttp://genomealberta.ca/blogs/main_ aspx Why spruce beetle? Allies: blue stain fungi

12 Why spruce beetle? Allies: mass attack

13 Why spruce beetle? Allies: warmer temperatures

14 Why spruce beetle? Lets increase the temperature

15 Why spruce beetle? life cycle: one year

16 Why spruce beetle? life cycle: one year

27 How is it still going? Lots of mature, even-aged standing spruce

28 How is it still going? Depends on: Site quality (good) Stand age (>100 years) Stand density and growth rate (DBH >30cm) Percentage of susceptible spruce (>20%) Elevation and aspect (warm, south-facing)

43 What are we doing? >16 C (1 st - 2 nd instars) Research! Funnel trap study Shelf life study Spruce beetle overwintering 2-year life cycle? 1-year life cycle

44 What are we doing? Research other potential projects Provenance trials to screens for resistant host trees? Ward Strong, Research Scientist, FLNRO Spruce beetle change detection via remote sensing? Alex Bevington, Research Earth Scientist, FLNRO Lethal trap trees replacements? Others?

45 Strategic planning Protect the midterm Maintain Ecosystem function

46 It is my expectation that FLNRO will continue to build strong connections with industry and the public to mitigate impacts from this outbreak and work as a team together for best results. It is important to maintain integrity, consistency and science in our collective approach on sanitation harvests. Diane Nicholls, Chief Forester
