This version is drivelill by alill EAB ilillvasioli1I wave model that assumes it takes 8 years for EAB to kill all the ash trees in your city after it has beeli1I detected in your c

  • u
  • li1lty. In this new version you can:
  • Stage your response to alill EAB ilillvasion based 01i11 the percentage of ash trees that are 1

dying.

  • Evaluate manaigemelillt plans mat reduce the frequelillcy of ash treat1

ment after me ini1 tial wave of EAB has passed through your forest

  • Compare the annual and cumulative costs over a 25 year period for ANJY management strategy that

includes a mixture of tree removal, replacement, and insecticide treatment.

  • Compare size of the forest rema.

ining over a 25 year period for ANY management straiegy that includes a mixture of tree removal, replacement, and insecticide treatment.

  • Geli1lerate prilillted reports of projected costs of up to 3 managemelillt strategies at a time.

To rnn the calculator you will need:

  • An inventory of the 1i11Umber and size of ash trees
  • An es

ti mate of costs for removing and treating trees based on the size of each tree.

  • An estimate of costs for replacing each ash tree that is removed.
