  4. Green ash (Fraxinuspensylvanica) • Grows in most soil types and is flood tolerant • Grows to around 70 feet tall • It is an early successional stage tree http://www.rook.org/earl/bwca/nature/trees/fraxinuspenn.html http://plants.usda.gov/java/largeImage?imageID=frpe_008_ahp.tif

  5. Black ash (Fraxinusnigra) • Grows in poorly drained soils. • Grows to 30 to 50 feet tall • Typically contains more leaflets than Green ash http://plants.usda.gov/java/largeImage?imageID=frni_008_ahp.tif http://www.rook.org/earl/bwca/nature/trees/fraxinusnig.html

  6. Emerald Ash Borer (EAB) Agrilusplanipennis • Adult beetles nibble on leaves causing some damage • The real damage come from their larvae who feed on the inside of the bark on the tree. This disrupts the transportation of water and nutrients. • Exit holes are D shaped and appear in June and July http://www.fs.fed.us/fstoday/2008/080822/images/03.0About%20Us/pests/EmeraldAshBorer_lg.gif http://www.entomology.wisc.edu/emeraldashborer/
