Climate Change & Gardening

  1. 1. Brooke Edmunds, PhD Oregon State University Extension
  2. 2. Cause of climate change? Increase in Greenhouse Gases Water vapor Carbon dioxide Methane Nitrous oxide CFC’s Figure: http://climate.nasa.gov/causes/
  3. 3. http://www.climate-lab-book.ac.uk/files/2016/05/spiral_optimized.gif
  4. 4. Effect in the PNW? • Predicted warming of 2.7ºF by 2030 & 5.4ºF by 2050 • Changes in precipitation? • Increased extreme weather events? (From: Scientific Consensus Statement on theLikely Impacts of Climate Change on the Pacific Northwest, 2004)
  5. 5. How could this affect our gardens? • Plant phenology changes • Exposed to new/different pest pressure Good Read: R. Bisgrove and P. Hadley. 2002. Gardening in the Global Greenhouse: The impacts of climate change on gardens in the UK. Technical report online.
  6. 6. What is plant phenology? Study of cyclic & seasonal natural phenomena • Bud break timing • Flowering • Fruiting • Leaf expansion • Fall leaf color • Dry matter Photo: http://depts.washington.edu/uwbg/wordpress/wp-content/uploads/bigleafflower.jpg

  8. 8. “Future projections suggest that warmer temperatures, longer growing seasons, and increased drought severity will stress Douglas-fir that are adapted to current climate conditions.” -Considering Assisted Migration for Trees in a Changing Climate on http://blogs.oregonstate.edu/orforestscc

  10. 10. 1st: Separate the effect of global trade & travel
  11. 11. 2nd: Effects on pest phenology? Figure: https://upload.wikimedia.org/wikipedia/commons/f/f3/Plant_Disease_Triangle.png Figure: http://www.420genetics.com/faq/pest/afig.2.JPG
  12. 12. Figure: http://www.420genetics.com/faq/pest/afig.2.JPG Increased generations within a growing season?
  13. 13. Stressed trees are more vulnerable Many insect species are attracted to stressed trees http://oregonforests.org/sites/default/files/blog_photos/Zombie_tree_feature.jpg
  14. 14. Precipitation can increase disease spread Phytophthora ramorum spread facilitated by heavy rain events (Rizzo & Garbelotto, 2003) Photo: http://www.nature.com/nature/journal/v466/n7308/images/466824a-f1.2.jpg
