Methods

• Plot area 1 ac (0.38 ha)
• Macrolichens collected from all woody
  substrates
• Rated in abundance on coarse 4 pt scale
• Sent to lichenologists for identification
• Lichens collected only by trained, certified
  crews
• QA protocols basic MQO, hot checks, blind checks

3
QA Rationale

• Determination of suitable MQO researched in
  multiple experts crews study (1994)
• Determine MQOs for indicator stability based on
  test of repeatability across observers
• Basic idea to arrive at similar locations on key
  multivariate gradients, crews and experts dont
  need same species capture rates
• MQO based on species capture required to achieve
  lt10 deviation on gradient scores
• MQO 65 of expert species capture

QA Basis for Indicator Operation

• Indicator methods reliable yielding tight
  clustering of scores for individual plots along
  gradients
• Repeatable across observers
