• Sensitive species monitoring
  • Started: 1990-08-01
    
  • Method Description: Native plant species known to be senstive to ozone and reliable bioindicators of ozone injury, are monitored annually to determine the presence/absence of injury on up to 10 individuals per species.

• Species monitored
  • Started: 1991-08-01
    
  • Method Description: Species monitored include milkweed, blackberry, black cherry and white ash.

• Voucher specimens
  • Started: 1993-08-01
    
  • Method Description: Voucher specimens sent to regional expert for verification.

• Species evaluation
  • Started: 1994-08-01
    
  • Method Description: Starting in 1994, 10 - 30 individuals of each species evaluated for the % of leaf area injured (amount) and severity of injury using a 5 scale rating system; and dogbane added as a bioindicator.

• Unnamed Method
  • Started: 1995-08-01
    
  • Method Description: Pin cherry added as a bioindicator species in 1995.

• Unnamed Method
  • Started: 1996-08-01
    
  • Method Description: Definition of amount of injury changed from % of leaf area to % of leaves with injury in 1996.

• Ozone concentrations
  • Method Description: One-hour average ozone concentrations recorded were obtained from the Vermont Air Pollution Control Agency.

• Classification and rating of injured foliage
  • Method Description: Classification/Rating methods of injured foliage: (1) A five class system- combines the percentage of injured leaves and the intensity of damage on the 10 most severely injured leaves. (2) An eight class system- rates 30 leaves on each of three terminal shoots from near the top of a tree, or the oldest 30 leaves on a smaller plant.

• Individual condition
  • Started: 1994-08-01
    Ended: 1995-08-31
    
  • Method Description: The location and type of injury recorded for each individual.
