• Label: amount_maximum

• Description: The maximum amount of injury for a given biological species at a hexagon equals the maximum value of all the injury amounts for that species. If there are no injured plants within the species, the maximum amount of injury for the species equals zero.

• 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.
